Peripheral devices expand the capabilities of a computer but are not part of the core architecture. There are three types: input devices which send data to the computer, output devices which provide output to the user, and storage devices which store processed data. Examples of input devices include keyboards and mice, while monitors and printers are common output devices. Peripherals connect to computers through various connection methods and cabling technologies such as USB, serial, and fiber optic cables.

1. Peripheral Devices

2. Objectives
 To understand what a peripheral device is
 To understand and identify different types of peripheral
devices
 To understand the difference between input & output
devices
 To explain the function of each device and the different
types available
 To understand the different methods of cabling

3. Peripheral Devices
Is a device that is connected to a host
computer, but not part of it.
It expands the host's capabilities but does
not form part of the core computer
architecture.
It is often, but not always, partially or
completely dependent on the host.

4. Types of peripherals
There are three different types of
peripherals:
Input, used to interact with, or send data
to the computer
Output, which provides output to the user
from the computer
Storage, which stores data processed by
the computer
