TYPES OF NETWORK

COMPUTER NETWORK

COMPUTER NETWORK

A computer network is a group of interconnected computers .

It consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications.

Lnked through cables, telephone lines, radio waves, satellites, or infrared light beams.

NEED OF NETWORKING

File sharing

Resource sharing

Remote access

Communication and collaboration

Data protection

NEED OF NETWORKING

TYPES OF NETWORKS

LAN WAN

Depending upon the geographical area covered by a network, it is classified as:

TYPES OF NETWORKS

LARGE AREA NETWORK

A LAN is a network that is used for communicating among computer devices, usually within an office building or home.

Is limited in size, typically spanning a few hundred meters

Requires little wiring, typically a single cable

)

LARGE AREA NETWORK

ADVANTAGES OF LAN

Users can communicate with each other very

easily.

Users can access their files from any

workstations.

When a new version comes out, it only has to be

loaded onto the server

Workstations can share peripheral devices like

printers.

ADVANTAGES OF LAN

DISADVANTAGES OF LAN

DISADVANTAGES OF LAN

Area covered is limited

Networks are difficult to set up and need to be maintained

by skilled technicians.

Costs for equipment and technology is very

expensive WAN.

Low bandwidth therefore it is easy to lose connection

METROPOLITAN AREA NETWORK

It is a network that is utilized across multiple buildings

Commonly used in school campuses or large companies

with multiple building geography to a single metropolitan

area

Examples of MAN: cable TV network

METROPOLITAN AREA NETWORK

ADVANTAGES OF MAN

• This type of connection can connect numerous locations

together in one municipality.

• MAN can cover a wider area than a LAN

• By running a large network connectedness, information can

be disseminated more widely, rapidly and significantly.

ADVANTAGES OF MAN

DISADVANTAGES OF MAN

DISADVANTAGES OF MAN

WIDE AREA NETWORK

A Wide Area Network is a network spanning a large geographical area of around several hundred miles to across the globe

The largest WAN in existence is the INTERNET.

WANs often connect multiple smaller networks, such as local area networks (LANs) or metro area networks (MANs).

It can be connected through cable, fiber or satellite.

WIDE AREA NETWORK

ADVANTAGES OF WAN

ADVANTAGES OF WAN

Expensive things

(such as printers or phone lines

to the internet) can

be shared

Data can be better

controlled when it's

centralized and

consolidated

Share information/ files over a larger area

It allows some

business persons to work from

home while still being

able to access work interfaces.

DISADVANTAGES OF WAN

allows business persons to work from home

Need a good firewall to restrict outsiders

requires network supervisors to maintain a network

Security is a real issue

DISADVANTAGES OF WAN
