25. What mammal, other than humans, uses a computer?
26. This teacher's web page is an example of:
_27.Digital versatile disc
DVD Video
For viewing movies and other visual entertainment. The total capacity is 17 Gbytes if two layers on both sides of the disk are utilized.
DVD-ROM
Its basic technology is the same as DVD Video, but it also includes computer-friendly file formats. It is used to store data. This product should supplant conventional CD-ROMs in the near future.
DVD-R
Its capacity is 4.7 Gbytes. Originally designed for professional authoring, a version for general consumer use is now under development. As with CD-R, users can write only once to this disk.
DVD-RAM
This makes DVD a virtual hard disk, with a random read-write access. Originally a 2.6-Gbyte drive, its capacity has increased to 4.7-Gbyte-per-side. It can be re-written more than 100,000 times.
DVD-RW
Similar to DVD-RAM except that its technology features a sequential read-write access more like a phonograph than a hard disk. Its read-write capacity is 4.7 Gbytes per side. It can be re-written up to about 1,000 times.
DVD Audio
The latest audio format more than doubles the fidelity of a standard CD. It is expected to become the most popular audio disk.
2.special characters like stars, hands, arrows, and geometric shapes you can use to decorate a document. A collection of dingbats is found in a popular font called Wingdings.
3.The handshake helps the modems determine how they will exchange information.
4.An introductory screen on the World Wide Web, used to welcome visitors.
5.
6.ENIAC was a product of World War II. The military needed to develop firing tables for its artillery, so that gunners in the field could quickly look up which settings to use with a particular weapon on a particular target under particular conditions.
7.. Ada suggested to Babbage writing a plan for how the engine might calculate Bernoulli numbers.

10 A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
11.A bit (short for binary digit) is the smallest unit of data in a computer. In most computer systems, there are eight bits in a byte. (four bits) is called a nibble
12.We called it online .
13. The world wide was created in 1990
14.it was posted in 1234 by sharlet shrinks
15.In 1970 the eight inch floppy disk drive was introduced by IBM.
16. Each second contains 75 sectors, each of which can hold 2048 bytes
17.Douglas Carl Engelbart had invented a number of interactive, user-friendly information access systems that we take for granted today: the computer mouse, windows, shared-screen teleconferencing, hypermedia, groupware, and more
18.Compact Disc-Read Only Memory.
19.Any external device that plugs into your computer, such as a printer, modem, scanner, or tape drive.
20.A GUI (usually pronounced GOO-ee) is a graphical (rather than purely textual) user interface to a computer.
21.Dvorak is an option on virtually every computer, but with the advent of new technologies, the traditional desktop/laptop computer might lose its place as the predominant typing environment. Also, some administrators are refusing to allow users to switch to Dvorak when the option exists. This is especially a problem in schools.
22.A computer virus is a program designed to spread itself by first infecting
executable files or the system areas of hard and floppy disks and then
making copies of itself. Viruses usually operate without the knowledge or
desire of the computer user.
