Typically, when connecting different types of devices, use a straight-through cable. And when connecting the same type of device, use a crossover cable.

1. Straight-through UTP Cables

A straight-through cable has connectors on each end that are terminated the same in accordance with either the T568A or T568B standards.

Identifying the cable standard used allows you to determine if you have the right cable for the job. More importantly, it is a common practice to use the same color codes throughout the LAN for consistency in documentation.

Use straight-through cables for the following connections:

- Switch to a router Ethernet port

- Computer to switch

- Computer to hub

Basic Networking Tutorial

What is a computer Network?

A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected using services available from phone companies, people can send e-mail, share links to the global Internet, or conduct video conferences in real time with other remote users. When a network becomes open sourced it can be managed properly. As companies rely on applications like electronic mail and database management for core business operations, computer networking becomes increasingly more important.
