What is an Intranet and what are its benefits?


An intranet is a privately maintained computer network that can be accessed only by authorized persons, especially members or employees of the organization that owns it.

The main purpose of an intranet is to share company information and computing resources among employees. An intranet can also be used to facilitate working in groups and for teleconferences over long distances. It is similar to the internet as users search for information, however it is rarely used to store information outside the scope of the users occupation and industry.


  1. Simple routine question and answers can be kept on the intranet to cut down on interoffice chatter.
  2. Form Finding. Do your employees spend time chasing paper ? trying to hunt down paper forms, reports, documents? How much time would be saved if each form is saved on the internet and is with a few key strokes of everyone's fingertips!
  3. Company Growth and targets. Having such information as the company's targets and goals for each employee can educate employees on how their jobs affect the company's targets and ultimately bottom line.
  4. Training. By having on-line training materials. Employees can learn during their work hours right at their own desks.

Ethernet crossover cable network


A simple, two-computer network between two computers can be created using an Ethernet crossover cable. As in any other TCP/IP network, each computer needs to be assigned a unique IP address. In this network configuration, a default gateway is not used and can be unspecified.

Example crossover network configuration using arbitrary unique IP addresses
Machine 1 Machine 2
IP address
Subnet Mask

Information on how to deploy such network on Windows systems can be found here
