Intranet

Many companies use intranets as well as the internet. The simple definition is “An intranet is a computer network based on internet technology, that is designed to meet the internal needs for sharing information within a single organisation/company”.

The main reasons for doing this include:

- safer since there is less chance of external hacking or viruses

- it is possible to prevent employees from accessing unwanted web sites

- companies can ensure that the information available is specific to their needs only

- it is easier to send out “sensitive” messages to remain within the company only

Some comparisons between internet and intranet include:

- the INTERNET is INTERnational NETwork

- an INTRANET is INTernal Restricted Access NETwork

- the intranet only gives local information relevant to the company/organisation

- it is possible to block access to certain sites using the intranet

- it is not always necessary to have external modems when using intranets

- information for use on intranets is stored on local servers

- the internet can be accessed from anywhere

- the internet is available to anyone, whereas the intranet requires password entry

- the intranet is behind a firewall
