Hardware data storage device developed by Iomega that functions
like a Standard 1.44" floppy drive. What makes the Iomega zip drive
unique is its capability to hold up to 100 MB of data or 250 MB of data on new
drives. Iomega Zip Drives became very popular in late 1990s, however, became
less popular as users needed larger storage capabilities. This drive was later
replaced by larger and cheaper CD-R and CD-RW drives and discs.
In the picture to the right, is an example of an Iomega Zip diskette. This
diskette is bigger than the standard floppy diskette and is made out of a much
harder plastic.
Computer Buses A computer system consists of different devices.CPU must be able to communicate with all devices. The devices are connected together by a communications channel called bus. A bus consists of a set of communication lines or wires. It is used to move a large amount of bits in the form of electrical pulses from one unit to another. The bus is used to connect the following units: Central Processing Unit Control Unit Arithmetic and Logic Unit Main Memory ( RAM, ROM) Input / Output Devices Bus is a common path to transfer data and commands between CPU, memory and input / output devices.It is also used to send or receive data from secondary storage.The capacity of a bus depends on the number of data lines in it.A bus with 16 lines can carry 16 bits or 2 bytes at a time. A bus with 32 lines can carry 32 bits or 4 bytes at a time . Types Of Buses Different types of buses are as follows: 1. Data Bus 2.Addres...
