This document discusses different types of computer networks. It defines a computer network as when two electrical devices connect for data communication. There are four main types discussed: storage area networks (SANs) which provide block-level data storage access; personal area networks (PANs) which connect devices around an individual; home area networks (HANs) which allow file and resource sharing between multiple home computers; and campus area networks (CANs) which interconnect local area networks within a university or campus.

2. Computer Networking
When two electrical devices are connected with each other for data
communication, they form a network.
Types of Networking:
1) SAN (Storage Area Network)
2) PAN (Personal Area Network)
3) HAN (Home Area Network)
4) CAN (Campus Area Network)

3. SAN (Storage Area Network)
A Storage area network is a dedicated network that provides access to
consolidated, block level data storage. SANs are primarily used to make
storage devices, such as disk arrays, tape libraries, and optical jukeboxes.
PAN (Personal Area Network)
This is a computer network organized around an individual person.
Personal area networks typically involve a mobile computer, a cell phone
or a handheld computing device such as a PDA. You can use these
networks to transfer files including e-mail and calendar appointments,
digital phones and music.
HAN (Home Area Network)
A home network is two or more computers interconnected to form
a local area network (LAN) within the home. In the United States,
for example, it is estimated that 15 million homes have more than
one computer. A home network allows computer owners to
interconnect multiple computers so that each can share files,
programs, printers, other peripheral devices, and Internet access
with other computers.

4. CAN (Campus Area Network)
 A Campus area network is made up of an interconnection of
LANs within a limited geographical area.
 For example, a university campus network is likely to link a
variety of campus buildings to connect academic colleges or
departments, the library, and student residence halls.
