Vista Training 101: The Basics

Wednesday, October 14, 2009

One of the many possible reasons why you are reading this article is that you decided to upgrade your Windows Operating System from Windows XP to Vista. Another reason could be that you purchased a new computer desktop PC or a laptop and it comes with pre-installed Windows Vista. For whatever reason or purpose you may have to learn how Windows Vista works, this tutorial is intended to make your learning experience worthy of your time.

The Start Menu

The Start menu is the main gateway to your computer’s programs, folders, and settings. It’s called a menu because it provides a list of choices, just as a restaurant menu does. And as “Start” implies, it’s often the place that you’ll go to start or open things.

Use the Start menu to do these common activities:

  • Start Programs
  • Open commonly used folders
  • Search for files, folders and programs
  • Adjust computer settings
  • Get help
  • Turn off the computer
  • Log off from Windows or switch to a different user account

Getting started with the Start menu

To open the Start menu, click the Start button in the lower left-hand corner of your screen or press the Window logo key on your keyboard.

The Start menu is divided into three basic parts:

  1. The large left pane shows a short list of programs on your computer. Your computer manufacturer can customize this list. Therefore, its exact appearance will vary. Clicking All Programs displays a complete list of programs (more on this later).
  2. In the lower left-hand corner is the search box, which allows you to look for programs and files on your computer by typing in search terms.
  3. The right pane provides access to commonly used folders, files, settings and features. It's also where you go to log off from Windows or turn off your computer.

Opening programs from the Start menu

One of the most common uses of the Start menu is opening programs installed on your computer. To open a program shown in the left pane of the Start menu, click it. The program opens and the Start menu closes.

If you don't see the program you want to open, click All Programs at the bottom of the left pane. Instantly, the left pane displays a long list of programs in alphabetical order, followed by a list of folders:

Clicking one of the program icons launches the program, and the Start menu closes. So what's inside the folders? More programs.

Click Accessories (see screenshot below), for example, and a list of programs that are stored in that folder appears. Click any program to open it. To get back to the programs you saw when you first opened the Start menu, click Back near the bottom of the menu.

If you're ever unsure what a program does, move the pointer over its icon or name. A box appears that often contains a description of the program.

For example, pointing to Calculator displays this message: "Performs basic arithmetic tasks with an on-screen calculator." This trick works for items in the right pane of the Start menu, too.

You might notice that over time, the lists of programs in your Start menu change. This happens for two reasons. First, when you install new programs, they get added to the All Programs list. Second, the Start menu detects which programs you use the most, and it places them in the left pane for quick access.

The Search box

The Search box is one of the most convenient ways to find things on your computer. The exact location of the items doesn't matter—the Search box will scour your programs and all of the folders in your personal folder (which includes Documents, Pictures, Music, Desktop, and other common locations). It will also search your e?mail messages, saved instant messages, appointments, and contacts.

To use the Search box, open the Start menu and start typing. You don't need to click inside the box first. As you type, the search results appear above the Search box in the left pane of the Start menu.

Click any search result to open it. Or, click the Clear button to clear the search results and return to the main programs list. You can also click Search Everywhere to search your entire computer, or click Search the Internet to open your web browser and search the Internet for your term.

Besides programs, files and folders, and communications, the Search box also looks through your Internet favorites and the history of websites you've visited. If any of these web pages include the search term, they appear under a heading called "Favorites and History."

What's in the right pane?

The right pane of the Start menu contains links to parts of Windows that you're likely to use frequently. Here they are, from top to bottom:

  • Personal folder. Opens your personal folder, which is named for whoever is currently logged on to Windows. For example, if the current user is Molly Clark, the folder will be named Molly Clark. This folder, in turn, contains user-specific files, including the Documents, Music, Pictures, and Videos folders.
  • Documents. Opens the Documents folder, where you can store and open text files, spreadsheets, presentations, and other kinds of documents.
  • Pictures. Opens the Pictures folder, where you can store and view digital pictures and graphics files.
  • Music. Opens the Music folder, where you can store and play music and other audio files.
  • Games. Opens the Games folder, where you can access all of the games on your computer.
  • Recent Items. Opens a list of files you've opened recently. Click one of the files in the list to open it.
  • Computer. Opens a window where you can access disk drives, cameras, printers, scanners, and other hardware connected to your computer.
  • Network. Opens a window where you can access the computers and devices on your network.
  • Connect To. Opens a window where you can connect to a new network.
  • Control Panel. Opens Control Panel, where you can customize the appearance and functionality of your computer, add or remove programs, set up network connections, and manage user accounts.
  • Default Programs. Opens a window where you can choose which program you want Windows to use for activities like web browsing, editing pictures, sending e?mail, and playing music and videos.
  • Help and Support. Opens Windows Help and Support, where you can browse and search Help topics about using Windows and your computer.

Power button (left); Lock button (right)

At the bottom of the right pane are two buttons: the Power button and the Lock button. Click the Power button to turn off your computer, or click the Lock button to lock your computer without turning it off. Once locked, your computer cannot be used until you unlock it with your password.

Clicking the arrow next to the lock button displays a menu with additional options for switching users, logging off, restarting, or shutting down.

Desktop Fundamentals

The desktop is the main screen area that you see after you turn on your computer and log on to Windows. Like the top of an actual desk, it serves as a surface for your work. When you open your programs or folders, they appear on the desktop. You can also put things on the desktop, such as files and folders, and arrange them however you want.

The taskbar is the long horizontal bar at the bottom of your screen. Unlike the desktop, which can get obscured by the windows on top of it, the taskbar is visible almost all the time. It has four main sections:

  1. The Start button , which opens the Start menu.
  2. The Quick Launch toolbar, which lets you start programs with one click.
  3. The middle section, which shows you which programs and documents you have open and allows you to quickly switch between them.
  4. The notification area, which includes a clock and icons (small pictures) that communicate the status of certain programs and computer settings.

How to Extend Laptop Battery Life?
Laptop computer batteries often run out of power sooner than would be desired. Here are some tips for making them last longer between charges...

Screensaver: Change your laptop's screensaver to a blank (Black) screen, and set it to turn on within a few minutes of inactivity. Screensavers with graphics and sound effects will drain the power more quickly, whereas a blank screen will conserve power.

Hard Drive & Disk Drive: Avoid using the hard drive and disk drive excessively. Because these are mechanical mechanisms, they consume more power. In some cases, upgrading the amount of memory will reduce hard drive usage. If your inspiron 6400 laptop is set to run anti-virus scans periodically, only allow this to happen when you have it connected to AC power, because this substantially increases hard drive usage while it is running. If you are using an older laptop with no hard drive, consider using a VDISK or RAMDISK (read more here) to reduce disk drive usage.

Sound/Music: If you want to listen to music while operating the computer, consider using a separate radio, cassette recorder, or CD player. If the CD player's batteries run out, you will be able to keep using the computer, which is probably your higher priority.

USB Devices: If your dell inspiron 6400 laptop computer has a USB port, keep in mind that some USB devices draw power from the computer's battery while they are plugged in to it. Avoid leaving such devices plugged in longer than they need to be.

Software: Different software which accomplishes the same functions may cause your dell inspiron 6400 battery computer to use different amounts of power. If the software utilizes memory more effectively (rather than reading/writing to the disk or hard drive frequently), it may use less power. Software which places less demand on the processor can also reduce power consumption in some cases, along with programs which use a dark-colored background. Avoid running software directly from a 3.5" disk or CD-ROM, because it will cause these mechanisms to run frequently and drain the power more quickly.

Quality Sources of Laptop Parts Online

Unfortunately, many of us come to a stage where our laptop and notebook isn´t functioning correctly, whether this be through wear and tear or an accident, the reassuring factor is that you can now source quality laptop parts online at competitive prices and be sure of a quick fix to get your laptop back up and running to full capabilities again. Laptops are becoming a part of our daily lives, much like cell phones did a few years back and knowing that you can get hold of laptop parts quickly and easily through the internet gives you some reassurance when things go wrong.

To purchase your laptop parts yourself doesn´t mean you have to be a laptop technician, but to have a basic understanding of the laptop is of great assistance. You may find that it is easier for you t purchase the laptop part at a great price online and if you decide not to fit the part yourself, or have a friend to do it for you then you will be saving fees with the laptop repair shop who will only charge for the repair, and not the laptop part at an extortionate rate.

As well as repair, which is the first thing we think of when you mention laptop parts, another option for the use of these parts is to upgrade, whether this be additional memory, a new processor or other part, having quality sources to obtain these laptop parts from can save you time and money in the long run and have your laptop upgraded to your desired specifications without the wait of it going n for upgrade at your local PC store where it sits on a shelf for days until a technician finally has time to deal with it.

We know there are endless stores online offering laptop parts nowadays, so seeking a quality supplier is a fundamental part of the process. When you are selecting where to buy your parts consider a few things other than price, such as delivery times, and costs, guarantees, shipping methods and reliability and feedback from previous customers. Providing you have knowledge of all these factors then you should have a quick and easy transaction when you purchase your laptop parts online.

Many people will opt for EBay, or other online auction sites for their parts – this is a good idea, but try to select a seller who is selling brand new parts, with guarantees and has a quality feedback rating which is clearly visible and up to date, this way you can be sure that you have confidence in the supplier of your laptop parts.

To get an idea of the perfect laptop parts supplier visit www.LaptopAid.com, where you will see a great layout, with great options, at great prices – just what we need when we need laptop parts.

Laptop memory

There are lots of people who always in a conscientious effort to upgrade memory in laptop to increase its effectiveness. In desktop systems, you are normally given three or four slots for memory modules but this scenario is not seen with laptops as they only come with two slots.

Normally, laptops don’t use SIMM and DIMM memory which is used in case of non portable machines. When you will delve more into the details, you will find that following are the basic types of memory used in laptops;

• 72 pin SODimm

• 144 Pin SODimm

• SDRAM

• DDR SDRAM

Certainly the more memory in a laptop PC the better but there are other concerns regarding memory in laptops. Laptops are generally more restricted when it comes to terms of memory that can be installed into a system. More often access to that memory can also be a headache if you plan a future upgrade.

Most of the laptops are now using the DDR2 memory technology, but a number of new laptops use the DDR3 standard.

We generally find two ways through which the memory speeds can be designated. The first one is by the memory type and by finding its clock rating, like DDR2 400. Another r method is by documenting the type along with the bandwidth. In this instance the same DDR2 memory would be listed as PC2-3200 memory. Below is a listing in order of lowest to fastest memory types in both formats:

  • DDR2 400 / PC2-3200

  • DDR2 533 / PC2-4200

  • DDR2 667 / PC2-5300 or PC2-5400

  • DDR2 800 / PC2-6400

  • DDR3 800 / PC3-6400

  • DDR3 1066 / PC3-8500

  • DDR3 1333 / PC3-10600

  • DDR3 1600 / PC3-12800

In addition to the type of memory installed in the laptop, the speed of the memory can also make a difference in the performance. When it comes in terms of comparision, it is of outmost importance to check both of these pieces of information to evaluate how they may impact performance.

Where Can I Get the Best College Laptop?

When shopping for the best college laptop, one always asks "Where do I go to purchase one? There are many places to go, in person or even on-line. I will talk about both of these choices here in this article.

As for going to the usual brick and mortar type establishments, there are many to choose from. One of the things that you need to ask is, "What brand do I want"? You can look in the phone book for the nearest Gateway store in you area. They have quite a few, but there's not one in every city. If you're one of the people that does have one in their hometown, then you should check them out. They have every model that they make in these store and with their well trained staff you will be taken care of.

Another one of your choices can be going to the nearest Dell outlet, but then again there's not one in every city. I myself have been in one in New York City and I found it very hard to walk out of there with just one item and when I decided on the one that I wanted it was difficult not to walk out of there with every single accessory that they offered me.

Most likely you will be happier shopping on line for the laptop of your choice since you can do it from the comfort of your own home. This is how I do most of my purchases for such items. Shopping this way will help avoid the salesmen type sales pitches that will come your way when go to the actual store.

Buying online you can save you money by looking up promotion and coupon codes and with the many choices of online stores, they will compete more for your business.

About Toshiba laptop battery test

Bear in mind, MobileMark is an industry benchmark test created by Bapco, a consortium that's headed and funded by Intel. Some of the biggest PC names also sit on this panel, including HP and Dell, and they provide tons of input as to which applications should be included in the benchmark test.

Even though AMD is part of this consortium, its input is probably underappreciated, since the majority of processors that run on these laptops are made by Intel. There's been a lot of debate, mostly influenced by AMD, about how Bapco's MobileMark 2007 unjustly represents toshiba satellite j60 battery , toshiba satellite j61 battery, toshiba satellite j62 battery life on laptops.

AMD's argument is that the industry should adopt a similar battery reporting style as cell phones and digital cameras, where there's an active and a standby score. The company has a valid gripe, but even so, MobileMark is still the best test out there.

AMD is proposing an active test, in which a gaming benchmark test like 3DMark06 or an HD video would be looped until the battery runs out. Thing is, almost no one does that. AMD is basically saying that MobileMark 2007 tests the equivalent of the standby time in cell phones. That's a little unfair. Granted, the laptop is using roughly 10 percent of the system resources and there are idle times during the test that brings CPU utilization down to nil. But while the test is made up of various business applications and emulates a day in the life of a business professional, the usage scenarios eat up as much battery life as surfing on the Internet all day.

Thing is, that is exactly what most people do with their laptops. They check their Facebook accounts, compose e-mail, write blog posts, and chat on IM. Although some users may be listening to music or watching videos—tasks that eat up 50 percent to 80 percent of the average CPU, and subsequently battery life, most people don't use all of the CPU's power for extended periods of time. Few people play games for three or fours hours straight on a laptop, and if they do they connect to an AC adapter. After all, CPU speeds would typically throttle down and impact gaming performance.

Looping an HD video is more realistic because users can get immersed in a movie or a video. But again, this doesn't represent the typical day in the life of a user. Sure, Bapco should to address this lack of an active component by introducing applications like iTunes, Windows Media Player, and looping Web pages filled with JavaScript and embedded videos. But that doesn't mean the current test is invalid. Put simply, MobileMark 2007 is the best test out there. It uses commonly used applications, such as Adobe products, Apple's Quicktime, and Macromedia's Flash.

AMD suggests giving two sets of battery scores, a low and a high rating, but this is no better than saying this laptop gives you two to five hours of battery life. We need a definitive score that addresses active and standby times because there are just way too many battery workload scenarios out there. Right now, there is no other recognized standard test available to reviewers.

We at b2c-battery.com.au use laptop battery as our battery test, but with some adjustments to make it more realistic. We don't crank down our display brightness settings to 20 percent, despite what Bapco recommends. We also leave wireless radios on, because unless you're on an airplane, a typical user would want to leave WiFi on. We do lower it halfway, though, acknowledging that our readers understand that display brightness will impact j50 battery life.

Perhaps most importantly, MobileMark allows us to test consistently. It offers a fair comparison of battery life across the swath of laptops on the market, at least for the scenario BapCo has created. Of course it could use improvement, but right now MobileMark is the fairest toshiba satellite j50 battery test on the market.

How to Ensure Total Security on Acer Laptops

Acer laptops are one of the most widely used laptops in the world. However, like every other computer system, you need to have total protection so that your laptop’s data is not hacked by anyone. Here are few steps that will ensure total security on your Acer laptops:

1. You should disable automatic connectivity to any wireless network to ensure that your laptop does not connect to any dangerous network. You can also set administrator id and password to connect to the wireless network. You should also enable WPA2 to ensure utmost security.
2. Activate the default firewall that came with your Windows XP or Vista. Firewall will block entry of untrustworthy application and prompt you if you want to allow or block the application. There are plenty of computer security application manufacturing companies like McAfee, Symantec and AVG that offer firewall with their computer security suite.
3. It is highly recommendable to install antivirus and antispyware on Acer laptops to ensure there is total security from viruses, spyware and other malicious programs. Make sure you regularly update these programs manually or automatically.
4. Do not click on too good to be true advertisements, do not download attachments from emails sent by unknown user and do not download software from unknown websites. Do not login with your username and password of your online banking or email accounts on any other unknown websites. You can become a victim of identity theft as in these ways; hackers may gain access to your bank accounts and email accounts easily if you do not take proper security measures.
5. Make sure you use a powerful web browser such as Mozilla Firefox and enable pop-up blocker to ensure you have safe browsing experience.
6. Encryption is very good way to protect your files from being accessed by anyone. You can do so by right clicking on any file or folder that you would like to encrypt and then click on Properties> Advanced button>Encrypt contents to secure data.
7. You can also create login name and password on your Windows XP or Vista PC. When you do this, you can access the desktop of your computer only after you enter the correct administrator password.
8. Make use of screen guard on you Acer laptops to ensure that nobody around you can see what you are viewing on your laptop.
9. Do not leave your laptop unattended inside the car or at any place. Always make sure that you carry your Acer notebook wherever you go.
10. Laptop locks are one of the best ways to fasten your laptop tightly to a strong table so that nobody can rob your laptop when you are away. Do not use cheap laptop locks because cheap ones can be easily broken by means of pliers.
11. Install laptop tracing application on your system so that you get accurate details about the location of the laptop incase your laptop is stolen.
12. Acer laptops come with fingerprint recognition security which means no one can access your notebook except you. It will only accept you after you place your finger on the finger print recognition sensor. Most Acer laptops come with an in-built webcam; you can install an additional face recognition application for more security.

REE Date Picker Script using Javascript

Date is an important part of any application to know when an activity has taken place, or to know the date of birth of a person. Usually in online applications date can be chosen using a calendar that displays and when the date is picked, it is displayed in the specified format.

Date Picker Script is used to pick the date from a drop down list box. One box will have the date values from 1 to 31, other will have from 1 to 12, and the year can be changed in the script itself, by changing the values in “startyear”, “endyear”. It also has a button to submit the above form fields.

Date Picker can be used in online application, or registration form to get the date of birth of the visitor. Date Picker can easily be embedded into any page by copying the JavaScript code from www.hscripts.com into the tag of the file.

Apart from web based application, JavaScript interpreters are embedded in a number of tools. Since JavaScript uses an interpreter, loosely-typed, and may be hosted in varying incompatible environments, a programmer has to take care to make the code execute as expected in multiple environments as possible.

Compared to other date picker that requires some kind of software installations, Date Picker script can be used with any online applications with ease. Most useful factor in this script is that the user can change the year range, so that the user entry can be restricted to a great extend. If the user needs the applications to be filled by people born in a specific year range can be made possible with the Date Picker Script.

.NET Framework

.NET Framework what is the role and how come?

Microsoft wants to come up with something standard so that everyone that everything can communicate to each other. Microsoft has invented a new system called .NET Framework is not an effective Operating System but the program will create an environment that can work in .NET If anyone has already used JAVA you may be familiar with the JAVA Virtual Machine .NET Framework it is considered as a Virtual Machine.

In the future, Microsoft hopes to bring.NET Framework is installed on all devices .NET Framework is divided into 3 large components Programming Languages, Base Classes Library, and Common Language Runtime.

Programming Languages

Language used to create programs that work under the conditions of .NET. Microsoft introduced language that would develop on .NET there are 3 numbers of the language all together.
• C # is a new language by Microsoft developed from C++ and JAVA language.
• VB.NET (Visual Basic.NET or Visual Basic version 7.0) is a language derived from Visual Basic version 6.0.
• Jscript.NET language development from a Jscript which is Microsoft's version JavaScript. These languages are an option that we have to use in the development of ASP.NET Web page with the following building-block.

Base Classes Library

Library is a group of commands provided for the programming language. The majority of the commands are commonly used. Therefore the inventor of memory to facilitate the programming within the Library system.NET will be in the form of that eclipse Called Class Library.
.NET has a mass amount of basic library and no matter what programming language you use to develop under .NET your entire Library series will be the same. Unlike before you can’t use the library from one language with the other language that means that each programming language has to have its own library. You can convert the source code from one language to another language one more easily.

Common Language Runtime (CLR)

Is the most important element in .NET Framework because CLR has a function that allows programs written in different languages to be converted into a language with the same standard format we call that language Microsoft Intermediate Language (MSL as known as IL) there for when you use the program to run on a different system CLR will translates IL to become appropriate to the system (converted into the system language of the machine).

NET Framework what is it good for?

Many will wonder why we write our program under .NET Framework and why it is better then programming the normal way.

1. The Library system has the same standard: Because the Library has the same standard. Allows us not to worry that the language of our writing is the correct Library or not, and you don’t have to worry that the Library that you use will not work in one's language.
2. Not the operating system: Because each operating system using MRI are not identical. However if the programming is running under .NET all you need is to have .NET Framework in your program it will allow the program to work on every supported operating systems.
3. All the language are the same: we do not have to study of new language every time you want to program some thing new and you can use the programming language that your most familiar with to develop you program.
4. A controlled environment: Because the system is standard. Distributed control systems are easy to use whether its memory allocation the machine can do the job faster and lowering the possibility of you computer crashing.
5. Security is more: .NET Framework has a security option called permission. That allows the user to set whether to use that part of the program or not Depending on the user and you also have a function to encrypt your data.

IT Outsourcing

Outsourcing has become a common practice these days. The practice facilitates transition of quality service from different corners of the world to companies that actually require them. Outsourcing is subcontracting a process, such as manufacturing or product design, to a third-party company. By way of outsourcing, companies are getting smarter solutions everyday and producing better service offers for their targeted customers.

If you are willing to make maximum benefits of effective outsourcing, options are many.

IT outsourcing services are becoming indispensable for companies dealing in any area of specialization. These services include a wide variety of services like networking facilities, hardware solution, software development solution, internet marketing solutions, maintenance solutions and many such others.

ITO or Information Technology Outsourcing services are basically an outsourcing of computer or Internet related work for example software programming etc.

Outsource is often results the interest of better use, lowering cost, save time and energy costs and thats why it is very important for any companies.

Offshoring and Outsourcing are used interchangeably in public discourse despite important technical differences.

Actually outsourcing involves contracting with a supplier, which may or may not involve some degree of offshoring and Offshoring is actually the transfer of an organizational function to another country.
There are different types of IT Outsourcing Services like a KPO and BPO outsourcing service. It also covers covers Data Entry Jobs,Software Development service, Website Designing & development, Data Processing related Outsourcing etc.

VietNam is good destinations of overseas IT outsourcing services.

VietNam and some other developing country has always been a major player in IT (information technology)

IT outsourcing is a cost-saving proposition towards reinforcing a business functioning with an advanced and cost-effective solution. Also, outsourcing solutions are meant for improving efficiency of companies’ way of functioning. It means that you can get cheap and hardworking manpower in lesser cost and get better results. There are many destinations like India, China, Philippines, and Russia that are becoming desired hubs for providing quality outsourcing IT services to the global companies. However, other countries are also joining the outsourcing club and to create a greater service market.

The main reasons for IT outsourcing are cost reduction, resource deficiency etc. Information Technology (IT) Outsourcing may also called IT Enabled Services (ITES) Outsourcing.
