Increased

Storage

Capacity

A

standalone

computer

might

fall

short

of

storage

memory,

but

when

many

computers

are

on

a

network,

memory

of

different

computers

can

be

used

in

such

case

One

can

also

design

a

Disadvantages

Following are some major
disadvantages
of computer networks

1
.

Security

Issues

One

of

the

major

downside

of

computer

networks

is

the

security

issues

involved
:

Cont



If

a

computer

is

a

standalone,

physical

access

becomes

necessary

for

any

kind

of

data

theft
.


If

a

computer

is

on

a

network,

a

computer

hacker

can

get

unauthorized

access

by

using

different

tools
.


Cont



In

case

of

big

organizations,

various

network

security

software

are

used

to

prevent

the

theft

of

any

confidential

and

classified

data
.

.

Rapid

Spread

of

Computer

Viruses

If

any

computer

system

in

a

network

gets

affected

by

computer

virus,

there

is

a

possible

threat

of

other

systems

getting

affected

too
.


Cont



Viruses

get

spread

on

a

network

easily

because

of

the

interconnectivity

of

workstations
.

Such

spread

can

be

dangerous

if

the

computers

have

important

database

which

can

get

corrupted

by

the

virus
.

.

Expensive

Set

Up

The

initial

set

up

cost

of

a

computer

network

can

be

high

depending

on

the

number

of

computers

to

be

connected
.

Additional

devices

like

routers,

switches,

hubs,

etc
.

can

be

very

pricey

4.
Dependency

on

the

Main

File

Server

In

case

the

main

File

Server

of

a

computer

network

breaks

down,

the

system

becomes

useless
.

In

case

of

big

networks,

the

File

Server

should

be

a

powerful

computer,

which

often

makes

it

expensive
