What are USB mini-Drive, and how are they used?

Back 1

They are also called pen, flash or jump drive. USB (Universal Serial Bus)ports in the back, front or side of the computer are hold from 28MB to 4GB of information storage.

Front 2

Explain CD-ROM,CD-R and CD-RW.

Back 2

CD-ROM: compact disc-read-only memory are removeable and hold approximately 650MB of information. CD-R: compact disc-Recordable, allows the user to record data once for storage purposes, and can not be be edited. CD-RW:compact disc-rewritable, also allows the recording of data, but also allows the user to edit the information after disc creation.

What are the purpose for Mouse Adaptations?

Back 3

The most common reason for the Mouse adaptation, is for children with physical disabilities. The various devices such as joysticks and trackball are simple for their usage. These devices can be plugged into the USB Port and may or may not require additional software for mouse emulation, or control of the cursor on the screen. With the trackball, the ball can be rotated with a pointing device. A single finger, the thumb, hand or even a foot can manipulate this device.

Front 4

Explain the difference between the Bits and Bytes etc?

Back 4

These are Memory Conversions: 1) Bit = a single binary number: a zero or one.
Byte= 9 bits: the binary code for one character of date, (01000001=A:01100001 =a.
Kilobyte (K/KB= l,024 bytes=1 K or appoximately 1,024 keyboard characters of information.
Megabyte (M/MB)=1,24 Kilobytes =1MB or approximate a million keyboard characters of information.
Gigabyte (G/GB)= 1,24 megabytes = 1 GB or approximately a billion keyboard characters of information.
Terabyte (T/TB_ = 1024 gigabytes - 1 TB or approximately a trillion keyboard characters of information

What is the purpose for the usage of an Electronic whiteboard?

Back 5

The Electronic Whiteboard serves the same purpose as the old traditional blackboard that is no longer used in the classroom, and also have extra features: serves as an dry-erase and active or interactive, whiteboard.

Front 6

In the Computer system, the peripheral devices, can you explain their functions?

Back 6

The peripheral devices are the support devices of the machine. 1) receive information or data as the user inputs it,2) process the information for the directions that the user defines and 3) output the information in a usable format. The processing of the information takes place in the Central Processing Unit (CPU), often referred to as the processor.

Front 7

Explain the Classroom response system or "clickers?"

Back 7

This is the latest trends in handheld devices; these devices usually wireless, allow students to respond to questions and relays input the gathered information into the teacher's laptop, and produce a histogram of answers.

Front 8

What are some storaged devices that can be used with computers?

Back 8

It is important to check the compatibility of the computer and the storage devices being used as well as the pros and cons of each devices type. Internal Storage: hard disk drive or hard drive,holds large amounts of information and is significant in the purchasing decision of a new computer system. External hard disk drives: can be connected to the computer through cables, these allow large quantities of data to be moved from the physical location to another. Includes: CDs, DVDs, and USB drives, zip drives and floppy disks.

Front 9

What is the purpose for the Software?

Back 9

Application software allows the computer to carry out specific functions, such as word processing, creation of databases and spreadsheets.

Front 10

Are there adaptation devices for the Monitor?

Back 10

Yes,and here are a few; the screen magnifier which allow the images to be magnified for easy view. Another is the Anti-glare filters, which are clear screens that fit over the monitors to reduce glare from overhead light and large windows. There are Monitor mounts which allow the placement of the monitors in the most easily seen position for viewal. and finally, the refreshable Braille display, this hardware is for the person that read Braille than listen to audio, or finds a voice display annoying this device lift pinpoint under a membrane to present a line of text from the screen in a Braille format. These points are cleared when the next line is displayed.
