Grade Level Requirements
|COMPUTER||A machine that processes information and performs computations.|
|The "box" or case that holds the parts that make up a computer: CPU, hard disk drive, floppy drive, memory chips, power supply, interface cards, etc. Click here to learn more.||
|CPU||Central Processing Unit, or "brains" of the computer|
|Monitor||An output display device (looks similar to a TV) in a computer system. You see information on the monitor's screen.||
|Screen||The viewing area on a monitor or the information or image displayed.|
|Disk Drive||A device that reads data from (input) or records data onto a disk for storage (output).|
|Hard Drive||The main device that a computer uses to store information. Most computers come with a hard drive, called drive C, located inside the computer case.|
means Read-Only-Memory - you can only "read" information, not
A CD can store a large amount of data including documents, photographs, software, and music (about 20 songs)
A CD-Recordable drive can put data onto a disk in just one session, and then is "closed" - one "burn" only - you can't add to it after you create it.
A CD-ReWritable drive can be written onto more than once - similar to a floppy or hard disk.
|DVD-ROM||Digital Video Disk - Read-Only Memory||Used to store full-length movies, large programs, etc.|
CD's, CD-R's, CD-RW's,
and DVD's all look the same.
Both CD's and DVD's are optical storage media. Optical technology uses a laser or light beam to process information.
|USB Flash Drive||These can hold documents, picures, and music. Some flash drives are also MP3 players.|
|Mouse||A hand-held input device you roll on your desk to point to and select items on your screen. When you move the mouse, the mouse pointer on the screen moves in the same direction.|
little symbol on your screen that you move with your mouse. You use the
mouse pointer to point to and select items on your screen. The mouse
pointer changes shape, depending on its location on your screen and the
action you are performing.
||Left Mouse Button - usually use this button|
|Right Mouse Button - occasionally use this button for "special" actions|
|Scroll Wheel - the mouse wheel may work differently from program to program. and it may not work in some programs. In most word processing programs, you can rotate the wheel to move up or down the page, equivalent to using the PAGE UP or PAGE DOWN keys on your keyboard or to clicking the scroll bar. Due to various problems it is best if you do not use the scroll wheel in the computer lab.|
|Click||Press and quickly release the button on a mouse|
|Double Click||Press and quickly release the mouse button twice.|
|Drag||Move objects or data around on the screen through the use of a mouse. Keep the left mouse button pressed while you move the mouse.|
|Speakers||Output device that produces sound and music when connected to the computer. Speakers come in different shapes and may even be in the monitor's case.||
|Headphones||Output device for listening that is held over the ears by a band worn on the head|
|Microphone||Input device in which sound energy is changed into electrical energy for the sending or recording sound (your voice).|
|Scanner||Input device that reads copy as an image and digitally records the image|
|Digital Camera||Records and stores images as a digital file, operates similarly to a "normal" camera, but no "film" is needed|
|Projector||Output device for displaying onto a large surface (projection screen) what appears on the computer monitor.|
|A device that produces a paper copy of the information on your screen. The printer on the left is an INK JET PRINTER, and the other is a LASER PRINTER.|
|Modem||A device that allows computers to communicate with each other over telephone lines (Internet). At school we do not use modems, we have a direct connection to the Internet called a T-1 line.|
device - choose letters, symbols, and actions by pressing keys
|Key||Any of the buttons on a keyboard that the user presses to
input data (information) or to type commands
pressed while you are working in a software application to stop the
current activity, back out of a menu (or screen), or return to a
|Enter||Used to move the cursor to the
a new line. It may also be called the return key. In some
applications, pressing Enter tells the computer to stop waiting for
more input and begin processing. Notice the arrow
symbol on the Enter key; it is sometimes used in instructions and means to press
the enter key.
the cursor one space to the left, erasing any character that is in its
the cursor one space to the right, leaving a small blank white area (space) on the screen.
||If the spacebar is "split", the left "spacebar" acts like the backspace key - it erases the character to the left of the cursor.|
|shift||Does nothing by itself, but when pressed and held down with another key it makes either a capital letter or the upper character on a key. Pressing Shift with a letter key when the CAPS LOCK key is "on" makes a lower case letter.|
|caps lock||Makes all letters uppercase without having to use the shift key - it is best to only use this when you are going to make many letters uppercase - don't use for just a few capital letters|
|tab||Marked with two arrows, one pointing left, the other, right. If pressed by itself, it moves the cursor to the next tab on the right. When pressed with the Shift key, it moves the cursor to the previous tab stop on the left.|
|alt||Does nothing by itself. When pressed with another key, it performs a special function. For example, pressing Alt-F4 may quit a currently running program.|
|ctrl||Does nothing by itself. When pressed with another key, it performs a special function. For example, pressing Ctrl-S may "save" a document.|
|Num Lock||Typically "on" at start up. When "on", it changes the keys on the numeric keyboard from cursor control arrows to numbers arranged in a typical ten-key calculator keypad.|
|Delete||On our "Windows" computers (P) it erases the character to the right of the cursor. Some people say it performs a "forward erase". It operates differently on a MAC.|
|End||The key you press to move the cursor to the end of the current line. Many programs also use keyboard shortcuts such as Ctrl+End to move the cursor to the end of a document.|
Changes between insert mode and overstrike mode in word processing programs. In insert mode, all characters typed are placed at the cursor position (or to the right of the insertion point). As you type, anything to the right of the cursor moves to the right to make room for the new typing. If insert mode is turned off, typing then overwrites (erases) the old characters instead of putting the new ones before the old ones. This is often called overwrite mode. Most PC keyboards have an Ins or Insert key that lets you switch back and forth between insert and overwrite modes. Many word processing programs display OVR in a status bar at the bottom when overwrite mode is on.
||The key you press to move the cursor to the beginning of the current line. Many programs also use keyboard shortcuts such as Ctrl+Home to move the cursor to the beginning of a document.|
|PgDn||The function of this key is usually software specific. Typically, it scrolls a document backward one screen or one page.|
|PgUp||The function of this key is usually software specific. Typically it scrolls a document forward one screen or one page.|
|Arrows||4 keys that move the cursor in the direction the arrow points|
Special keys that perform a number of important tasks. Their exact functions are software dependent. F1 usually is reserved for Help, while F10 frequently exits or quits the program.
|Print Screen||It directs the computer to copy whatever is displayed on the screen to the clipboard for pasting later. It doesn't really "print" in Windows.|
|Scroll Lock||Its function is often software specific. In spreadsheets, it usually locks the cursor on its current screen line and scrolls text (rather than the cursor) up or down whenever an up or down cursor control arrow is pressed.|
|Pause||Not usually used with Windows. Pressing this key under DOS temporarily stops a screen display or freezes rapidly scrolling information.|
|Windows Key||The WINDOWS key acts as another special function key. If you press the Window key by itself, the Start Menu will open. Windows+E will launch Windows Explorer.|
