We can define a computer as a device that accepts input, process data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can be classified as mainframes, minicomputers, workstations, or microcomputers. All el (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.
Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC, introduced in the early 1950s, were bad on vacuum tubes. Second-generation computers, appearing in the early 1960s, were tho in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale in
tegration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.

CD-ROM stands for compact disk read-only memory. Unlike floppy and hard disks, which u magnetic charges to reprent 1s and 0s, optical disks u reflected light. On a CD-ROM disk, 1s and 0s are reprented by flat areas and bumpy areas (called “pits”) on its bottom surface. The CD-ROM disk is read by a lar that projects a tiny beam of light on the areas. The amount of reflected light determines whether the area reprents a 1 or a 0.
Like a commercial CD found in music stores, a CD-ROM is a “read-only” disk. Read-only means it cannot be written on or erad by the ur. Thus, you as a ur have access only to the data imprinted by the publisher.
A single CD-ROM disk can store 650 megabytes of data. That is equivalent to 451 floppy disks. With that much information on a single disk, the time to retrieve or access the information is very important. An important characteristic of CD-ROM drives is their access rate.
