On this occasion we will discuss about the definition CISCO Router.
Cisco is the main equipment that is widely used in Wide Area Networks or Wide Area Network (WAN). With Cisco routers, the information can be forwarded to the addresses that are far apart and located on a different computer networks. Which aims to be able to forward data packets from one LAN to another LAN.
Cisco routers use routing tables and protocol that serves to regulate the data traffic. Data packets arrive at the router is checked and forwarded to the addressee. In order for the received data packet to reach the destination quickly, the router must process the data with very precise. To that end, Cisco routers using the Central Processing Unit (CPU) as used in the computer to process data traffic quickly.
Like computers, Cisco routers also have some kind of memory is ROM, RAM, NVRAM and FLASH, which is useful to help work the CPU. In addition it is also equipped with a number of interfaces to connect with the outside world and out of the data.
The operating system used by Cisco routers are the Internetwork Operating System (IOS).
The memory used by Cisco routers each having its own utility as follows:
• ROM is useful for storing bootstrap system that serves to regulate the process of booting and running the Power On Self Test (POST) and the IOS image.
• RAM is useful for storing and running configuration and IOS operating systems are active.
• NVRAM configuration is useful for storing the initial (start-up configuration).
• FLASH useful for storing IOS image. By using FLASH, a new version of IOS can be obtained from the TFTP server without having to replace components in the router.
Thus a review of Understanding CISCO Router.
