7 Data Interfaces
7.1 Introduction
In addition to their Central Processing Unit (CPU), computer systems usually
include various peripheral devices.
A CPU is, for example:

PC

Control
Peripheral devices include:

Printers

Scanners

External storage devices, such as hard disks, floppy-disk drives or USB
memory sticks.

Other computer systems
A data interface makes it possible for the CPU and its peripheral devices to
communicate.
The interfaces, which consist of physical links between the computer system
and the peripherals, need a transmission line and appropriate software in order
to transfer data between the individual units.
Standard interfaces include:

Ethernet

USB 2.0

RS-232-C/V.24 or

RS-422/V.11
