If we want to know exactly what routers are we need to come back at the age at which the internet began, It that time we had many local offices and in those offices connected computers. Each computer had its own Network interface card (NIC) and each NIC had its own MAC address.

That system worked fine until someone came up with the idea of connecting two offices. The problem was the fact that in those two offices we had two computers with the same Mac address. You can not communicate if you do not know which of those two computers is going to take the frame you sent him, We needed a system above the one we had.

Instead of physical Mac address, IT tech freaks came up with an IP address, a logical name for your PC that was given to you within the system. A device that gave you your IP address was called DHCP server and his location was usually in the router.

As I just wrote, SOHO (small office home routers) usually contain DHCP servers that grant you your IP address and other network information, but that is not all that it does.

There are many functions related to routers. I will not cover them all here in this article.

Today’s most common types of CISCO SOHO routers contain not just that device but a series of connected devices within the box. modems, wireless access points, switches, firewalls are all part of it.
