At the end of our tutorial, you are expected to;
• Understands the basic concepts in computer
network technology
• Identify the different types of network

INTRODUCTION
A computer network is a group of
computer that shares information
or data that linked together in the
same communication medium.

Local area network
A Local area network (LAN), or, in
other words, small network
constrained to a small geographic
area. An example of a LAN would
be a computer network within a
building.

Personal area network
A Personal Area Network (PAN) is a
computer network used for
communication among computer
devices, including smartphone and
tablet, in proximity to an
individual's body.

Wide area network
A wide area network (WAN) is a
computer network that covers a
broad area (i.e., any network whose
communications links cross
metropolitan, regional, or national
boundaries).
The largest WAN in existence is the
Internet.

Metropolitan area network
A metropolitan area network
(MAN) is a hybrid between a LAN
and a WAN. Like a WAN, it
connects two or more LANs in the
same geographic area.

Storage area network
A storage area network (SAN) is a
dedicated storage network that
provides access to consolidated,
block level storage. SANs are used
primarily to make storage devices
(such as disk arrays) accessible to
servers so that the devices appear
as locally attached to the operating
system.

The Internet
It is a network of networks that
consists of millions of
interconnected devices, that are
linked by a broad array of
electronic, wireless and optical
networking technologies.

Virtual Private Network
A VPN is a private network that is constructed within a public network infrastructure
such as the global Internet. a telecommuter can access the network of the company
headquarters through the Internet by building a secure tunnel between the
telecommuter’s PC and a VPN router in the headquarters. It is a mechanism for
providing secure, reliable transport over Internet. VPNs are frequently used by
remote workers or companies with remote offices to share private data and network
resources.

Server-Based Network
The term Client/server refers to the concept of
sharing the work involved in processing data
between the client computer and the server
computer.
The client/server network is the most efficient
way to provide:
Databases and management of applications
such as Spreadsheets, Accounting,
Communications and Document
management.
Network management.
Centralized file storage

Peer to peer network
There are no dedicated servers or hierarchy
among the computers.
All of the computers are equal and therefore
known as peers.
In peer-to-peer (P2P) networks, each computer
acts as both a server and a client. Examples of
P2P software include Skype and BitTorrent.

The largest WAN in existence is the
Internet.
A. TRUE B. FALSE

In peer-to-peer (P2P) networks, each
computer acts as both a server and a
client.
A. TRUE B. FALSE

Local area network (LAN), or, in other
words, small network constrained to a
small geographic area.
A. TRUE B. FALSE
