What is Network
Collection of computers and devices connected via
communications devices and transmission is called network.
media

Types of Network
 LAN
 MAN
 WAN
 PAN
 VPN
 HAN
 Peer-to-peer
 Client to server

LAN:
A local area network (LAN) is a computer network that
interconnects computers within a limited area such as a residence,
school, laboratory, university campus or office building and has its
network equipment and interconnects locally managed.

Examples:
 Ethernet and Wi-Fi
 Networking in home, office.
 Networking between two computers.
 Wi-Fi (When we consider wireless LAN)

1. Resource Sharing
2. Software Applications Sharing
3. Easy and Cheap Communication
4. Data Security
5. Internet Sharing
1. Privacy Violations
2.Data Security Threat
3. Covers Limited Area
4. LAN Maintenance Job
5. High Setup Cost

MAN:
A Metropolitan area network (MAN) is a network that
interconnects users with computer resources in a geographic area
or region larger than that covered by even a large local area
network (LAN) but smaller than the area covered by a wide area
network (WAN).

Examples:
Metropolitan area networks of various sizes can be found
in the metropolitan areas of London, England; Lodz, Poland; and
Geneva, Switzerland. Large universities also sometimes use the
term to describe their networks.

1.It provides good back bone or
large network and provide grater
access than wans.
2. The man usually encompasses several
blokes of city or an entire city.
1. More cables required for man connection
from one place to another .
2. It is difficult to make the system
secure form hackers and industrial
espionages

WAN:
A wide area network (WAN) is a
geographically distributed private
telecommunications network that interconnects multiple
local area networks (LANs). In an enterprise, a WAN may
consist of connections to a company's headquarters, branch
offices, colocation facilities, cloud services and other
facilities.

Types Of WAN connections:
 WAN technologies, based on the 4G LTE standard, are gaining
traction
 Public Wi Fi or satellite networks.
 WAN infrastructure may be privately owned or leased as a
service from a third-party service provider, such as
a telecommunication carrier, internet service provider, private
IP network operator or cable company.

Example
Internet is the example of WAN.

1. Covers a large geographical area
so long businesses can connect on
the one network .
2. Everyone on the network can use
the same data .This avoid the
problem where same user may have
older information.
3.Massage sent and receive
(audio,vedio,images, text) best e.g.
Skype, Whatsapp.
1. Need a good firewall to restricted for
outsiders from entering disturbing the
network .
2. Security is real issue most of people
hacker and made viruses to their PCs
and stole the important files.

Example:
The good example of personal area network is
Bluetooth.

1. Every information which are stored in
the devices which are shared via network
with authorized peoples only. So there is
secure file transfer between device
2. This is the basic concept for wearable
computing.It gives royal look and which
makes work simple.
3.It is use in portable devices such as
PDAs.
1. in this lot mostly devices are used for
communication. wireless uses microwave
signals as medium for make
communication path.
2 Long time working with this radius
signals will leads some brain related
problems, and heart related problems
3. This network uses devices which are
may expensive such as
smartphones,laptops,Digi camera, PDA...
etc.

VPN:
A virtual private network (VPN) is a technology that
creates an encrypted connection over a less secure network.
The benefit of using a secure VPN is it ensures the
appropriate level of security to the connected systems when
the underlying network infrastructure alone cannot provide
it. The justification for using VPN access instead of a
private network usually boils down to cost and feasibility:
It is either not feasible to have a private network

Examples:
The instructions are send from head office to the
regional offices through internet

Examples:
( Image, HTML, PDF file, MS PowerPoint
Presentation, Adobe Flash or MS Visio
XML

Peer to Peer :
Simple network that connects fewer than 10
computers each computer, or peer, has equal capabilities.

Examples:
If User A's PC is connected to a printer that
User B wants to access, User A must set his machine to
allow (share) access to the printer. Similarly, if User B
wants to have access to a folder or file, or even a complete
hard drive, on User A's PC, User A must enable file sharing
on his PC. Access to folders and printers on an office P2P
network can be further controlled by assigning passwords
to those resources.

1. Cheaper cabling cost.
2 .Normally used in small networks
with less than10 computers.
3.No server need.
1. All computer have equal ability.
2. Hard to manage.
3.Install to every computer.

Client to server:
One or more computers act as server
and other computers, or clients, access server is called
client to server network.

Example:
In lab there are one server computer and many
client computers.
In companies.
In education departments.

1.Server has control ability while
client’s don’t.
2. It is used in small and large area
networks.
3. Easy to manage.
4.Install software only in the server
computer while client’s share the
software.
1.Higher cabling cost
2.One powerful computer acting as
server.
