Partition

To divide memory or mass storage into isolated sections. In DOS systems, you can partition a disk, and each partition will behave like a separate disk drive. Partitioning is particularly useful if you run more than one operating system. For example, you might reserve one partition for Windows and another for UNIX.

In addition, partitioning on DOS and Windows machines can improve disk efficiency. This is because the FAT system used by these operating systems automatically assigns cluster size based on the disk size: the larger the disk, the larger the cluster.

Unfortunately, large clusters can result in a wasted disk space, called slack space. There is an entire sector of the software industry devoted to building utilities that let you partition your hard disk.

WYSIWYG (What You See Is What You Get)

Pronounce it WIZ-zee-wig. Short for what you see is what you get. A WYSIWYG application is one that enables you to see on the display screen exactly what will appear when the document is printed. This differs, for example, from word processors that are incapable of displaying different fonts and graphics on the display screen even though the formatting codes have been inserted into the file. WYSIWYG is especially popular for desktop publishing.

Note that the WYSIWYGness of an application is relative. Originally, WYSIWYG referred to any word processor that could accurately show line breaks on the display screen. Later WYSIWYGs had to be able to show different font sizes, even if the screen display was limited to one typeface. Now, a word processor must be able to display graphics and many different typefaces to be considered WYSIWYG. Still, some WYSIWYG applications are more WYSIWYG than others. For example, many desktop publishing systems print text using outline fonts (PostScript fonts, for example).

Many of these systems, however, use corresponding bit-mapped fonts to display documents on a monitor. What you see on the display screen, therefore, is not exactly what you see when you print out the document. In addition, standard laser printers have a resolution of at least 300 dpi, whereas even the best graphics monitors have resolutions of only 100 dpi. Graphics and text, therefore, always look sharper when printed than they do on the display screen. And colors often appear differently on a monitor than they do when printed out.

Internet address

Internet address
It is an Internet address. While you are in your browser (which you are probably in now) you will see a section at the top of the page that is titled “location”. If you type in the address of someone’s web page and hit enter, your browser will take you to that page. However the address you type in the location bar must be an exact match.

Load
It means download and upload. If someone asks how long did the page take to load? He/She is referring to the time it takes a page to appear on your screen. If a web page is loading slowly it means that it’s taking a long time to fully appear on your screen. You can often scroll through a page and look at the parts that have loaded while the rest of the page continues to load. Also, you can usually click a link on the page you are loading and link to another page without waiting for the current page to fully load.

Once you access to the Internet you are online. Often people will say they are online meaning they have access to the Internet and have an e-mail address, but may not necessarily be connected to the Internet at that moment.

What you need while surfing the web. Some web pages seem to take forever to fully appear on your screen - [Patience].

Selecting Items by Access Key or by Name

Most dialog box controls, menu titles, and menu items have underlined access keys. You can press ALT along with the access key to activate the control or menu anywhere within the active window. If an item doesn't have an underlined character, its access key is the first character in its name.

Access keys can sometimes be used without the ALT key for choosing controls or menu items. Use access keys without ALT to select items from an open menu. You can choose a dialog box control by typing its access key alone, except when the focus is on an edit box, a list box, or another control that expects typed characters. Therefore, using the ALT is a more reliable method.

Choosing controls in this way normally activates them, except when more than one item has the same access key. In that case, it will navigate to the next item assigned that key, but will not activate it. You must then press ENTER to activate it.

Within a list box, list view, tree view, or on the desktop, you can select an item by typing the first one or more characters in its name. You can begin typing a new name by pausing, and in some cases by pressing BACKSPACE. Pressing the same character more than once at the beginning of a name will select the next item beginning with that character.
