Windows 7 is the latest public release version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, netbooks, tablet PCs, and media center PCs. Windows 7 was released to manufacturing on July 22, 2009, and reached general retail availability on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time.
Unlike its predecessor, which introduced a large number of new features, Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being fully compatible with applications and hardware with which Windows Vista is already compatible.
Presentations given by Microsoft in 2008 focused on multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements. Some applications that have been included with prior releases of Microsoft Windows, including Windows Calendar, Windows Mail, Windows Movie Maker, and Windows Photo Gallery, are not included in Windows 7; most are instead offered separately as part of the free Windows Live Essentials suite.
Internet Spades, Internet Backgammon and Internet Checkers, which were removed from Windows Vista, were restored in Windows 7. Windows 7 includes Internet Explorer 8 and Windows Media Player 12.
In July 2009, in only eight hours, pre-orders of Windows 7 at Amazon.co.uk surpassed the demand Windows Vista had in its first 17 weeks. It became the highest-grossing pre-order in Amazon's history, surpassing sales of the previous record holder, the seventh Harry Potter book. After 36 hours, 64-bit versions of Windows 7 Professional and Ultimate editions sold out in Japan. Two weeks after its release, it was announced that its market share had surpassed that of Snow Leopard, released two months previously as the most recent update to Apple's Mac OS X operating system. According to Net Applications, Windows 7 reached a 4% market share in less than three weeks. In comparison, it took Windows Vista seven months to reach the same mark. As of January 29, 2010, Microsoft announced that they had sold more than 60 million Windows 7 licenses. Reviews of Windows 7 were mostly positive, praising its usability when compared to its predecessor, Windows Vista. CNET gave Windows 7 Home Premium a rating of 4.5 out of 5 stars, stating that it "is more than what Vista should have been, [and] it's where Microsoft needed to go". PC Magazine rated it a 4 out of 5 saying that Windows 7 is a "big improvement" over Windows Vista, with fewer compatibility problems, a retooled taskbar, simpler home networking and faster start-up.
Some Vista Ultimate users have expressed concerns over Windows 7 pricing and upgrade options. Windows Vista Ultimate users wanting to upgrade from Windows Vista to Windows 7 must either pay $219.99 to upgrade to Windows 7 Ultimate or perform a clean install, which requires them to reinstall all of their programs.
Microsoft is offering a family pack of Windows 7 Home Premium (in select markets) that allows installation on up to three PCs. The "Family Pack" costs US$259.99 in the United States; it was available at a cost of US$149.99 for some weeks when it was first introduced.

A USB flash drive consists of a NAND-type flash memory data storage device integrated with a USB (universal serial bus) interface. USB flash drives are typically removable and rewritable, much smaller than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and most USB flash drives weigh less than an ounce (28g). Storage capacities typically range from 64 MB to 128 GB with steady improvements in size and price per gigabyte. Some allow 1 million write or erase cycles and have 10-year data retention, connected by USB 1.1 or USB 2.0.
USB flash drives offer potential advantages over other portable storage devices, particularly floppy disks or the COMPACT DISC (CD). They have a more compact shape, operate faster, hold much more data, have a more durable design, and operate more reliably due to their lack of moving parts.
Additionally, it has become increasingly common for computers to be sold without floppy disk drives. USB ports, on the other hand, appear on almost every current[update] mainstream PC and laptop. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Windows, Mac OS X, Linux, and other Unix-like systems.
Nothing actually moves in a flash drive: the term drive persists because computers read and write flash-drive data using the same system commands as for a mechanical disk drive, with the storage appearing to the computer operating system and user interface as just another drive.
A flash drive consists of a small printed circuit board protected inside a plastic, metal, or rubberised case, robust enough for carrying with no additional protection—in a pocket or on a key chain, for example. The USB connector is protected by a removable cap or by retracting into the body of the drive, although it is not liable to be damaged if exposed. Most flash drives use a standard type-A USB connection allowing plugging into a port on a personal computer.You can transfer photos from your camera directly to your USB Flash Drive as well.
There are numerous solutions for importing digital pictures from your camera to your hard drive. I typically just connect my digital camera to my PC and copy the files over using Windows Scanner and Camera Wizard.
If you prefer to use an external application, Google's Picasa is an excellent solution. So is Photobucket, and Flickr. In addition to being a convenient way to manage your images, Picasa also includes common photo editing functions and assists in uploading images to the Web or creating slideshows on your local system.
One of my favorite features of Picasa is a timeline that shows when images were taken in relation to all your other images (which only works if your digital camera is set to the correct date). Picasa is free for Windows 2000, Windows XP, and Linux.
After you take pictures with your digital camera, you'll want to copy the pictures from your camera to your computer so you can print them, share them with others, and back them up for safe keeping. Once your pictures are on your computer, you can erase them from your camera, freeing up memory so you can take more pictures. You can also view your pictures on a larger screen and decide which ones are worth keeping.
Some digital cameras come with software that helps you copy pictures from your camera to your computer. You can use this software, but you don't have to.
Windows XP can copy pictures to your computer without requiring additional software.
Windows XP opens a Windows Explorer window showing the pictures you downloaded from your camera. Your camera's memory card is now clean and ready to store new pictures. If you connected your camera to your computer using a USB cable, disconnect your camera. If you used a memory card reader, return the memory card to the camera.
Digital cameras and computers have revolutionized photography. Whether photography is your profession or a hobby, the ability to transfer your pictures from your camera to a flash drive without needing a computer is a bonus. Purchase a few accessible and inexpensive devices, or a full-featured tool, in order to quickly move your images to your flash drive and immediately continue taking pictures.
Transferring Photos from memory card to USB Flash Drive
(We don't have a memory card reader in the lab)
You can transfer photos from your camera directly to your USB Flash Drive as well. Demonstrate. Requires 2 USB ports.
Copying files and folders to a CD
- Insert a blank CD into the CD recorder. Use one of the following:
- Recordable compact disc (CD-R)
- Rewritable compact disc (CD-RW)
With rewritable CDs, you can copy data to and erase data from the CD multiple times.
- Click Start, and then click My Computer.
- Click the files or folders that you want to copy to the CD.
- To select more than one file, hold down the CTRL key while you click the files you want. Then, under File and Folder Tasks, click Copy this file, Copy this folder, or Copy the selected items.
- If the files are located in My Pictures, under Picture Tasks, click Copy to CD or Copy all items to CD, and then go to Step 5.
- Do not try to copy more files to the CD than it will hold. Check the CD packaging to see the capacity of each CD. For files too large to fit on a CD, you can copy files to a recordable DVD (DVD-R or DVD+R) or rewritable DVD (DVD-RW or DVD+RW). However, Windows XP does not support copying to a DVD, so you have to use DVD authoring software.
- Make sure that you have enough disk space on your hard disk to store the temporary files that are created during the CD-writing process. For a standard CD, Windows reserves up to 700 megabytes (MB) of the available free space. For a high-capacity CD, Windows reserves up to 1 gigabyte (GB) of the available free space.
- After you copy files or folders to the CD, you can view the CD to confirm that the files have been copied.

What's a BROWSER?
Definition: A browser is a software program that lets you explore the World Wide Web to find text, graphics, sound, movies, games, chats and more.
Bookmarks and Favorites
With over 100 million websites and more coming online daily, you will undoubtedly find ones you want to revisit. Bookmarks and Favorites save
To save a web page, go to Bookmarks or Favorites on the menu bar and click on Add to... When you open your list, the title of the page you added will appear at the bottom of the list. To access the page, double-click on the title.
Here's another way to bookmark a web page: click on this page once with your right mouse button and select Add Bookmark or Add to Favorites from the pop-up menu.
Put Your Links in Order
After a while you'll discover that you've got dozens of bookmarks. It's now time to organize them into folders.
URL stands for Uniform Resource Locator. It is the Web Address of a web page, or some other kind of document, that is available on the Internet. It is the instruction to your browser regarding the exact location on the Internet of the page you want to visit.
For example: http://www.cnn.com OR http:// beyondthebasics5.blogspot.com
The way that information is transferred by way of the browser. That is known as the protocol. In this case the browser is to use Hyper Text Transfer Protocol. (http://) The language of web pages is known as HTML, Hypertext Markup Language.
The domain name is the location of the computer on the World Wide Web which hosts the page. Once a domain is registered the information provided by that domain must have a host computer where the files are stored.
That computer is called a server. Some places are huge collections of servers known as “server farms.” Servers which host huge collections of data must organize that data in directories or file folders. Anything following the domain name which is also followed by a slash is the name of a directory. Very large collections of data may require sub-directories, or folders within folders.
Each file in the directory must have a unique name. Some get very complicated. Spaces should not be in file names.
A URL can be typed into the address box on your browser. Type carefully, if one character is wrong you will not get to the page. After typing in the URL press the Enter key to go to the page.
Usually you will use a URL by following a link on another web page. After reading these instructions go to http://cnn.com/. When you get there put your cursor over the CNN URL, but do not click. Your mouse pointer will change to a hand indicating that the words are a link to another page. Look in the status bar, the gray bar at the bottom of your browser window. You will see the URL of the place those words link to.
Navigating the Internet (IE)
