Compact Disc - Read Only Memory. A CD-ROM is any compact disc which contains computer data. These discs can store huge amounts of data (up to 640 megabytes). If there is a large amount of data on a CD-ROM, then it is usually impractical to copy the data on to the hard disk; in this case, you must insert the disc whenever you want to use the data. The ROM simply means that you can not save information onto these discs. CD-ROM may also refer to the drive used to read these discs.

37⟩ What is Insertion point?
A vertical flashing line that shows the user where text will be inserted.
38⟩ What is Binary?
Binary is an alternative number system which works very well for computers. Humans have ten fingers; that's probably why we use ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) in our number system (decimal), but it is easier for a computer to use only two digits (0 and 1). Ones and zeros can be represented with high or low voltage, closed or open switches, aligned or misaligned magnetic particles, etc. A byte is a group of eight bits, and it is the standard unit by which data is stored. There are 256 different combinations of zeros and ones you can make with one byte, from 00000000 to 11111111. This is enough to cover all the ASCII characters. If more than 256 values are needed, then more than one byte can be used. With two bytes, there are 65536 possible combinations of ones and zeros. These bytes can represent any kind of data. For example, a picture may be made up of thousands of pairs of bytes, with each pair of bytes representing a single dot in one of 65536 colors. Put together all these dots (known as pixels) and you have a full-color picture (most picture data is also compressed). On systems using Microsoft Windows, the meaning of data stored on a disk is determined by the file's extension. For example: if it is TXT, then it is ASCII text; if it is EXE, then it is a program (an executable).
39⟩ What is Icon?
An icon is a picture used to represent an object. Some example objects are: data files, program files, folders, email messages, and drives. Each type of object has a different icon. That means that different types of files each have an icon representing its file type. MS Word files will have the MS Word icon; MS Excel files will have the MS Excel icon; Etc.
40⟩ What is Inactive window?
A window that is open but is not active.
