Definition: be understood that is a search device find the best link to send and received the signaling in the network system
Role: Usually LAN system is a model single network connection, the peripherals, computers, printers and other terminals connected together within a geographic range is limited. Meanwhile systems for WAN connectivity in the global geographical scope. So enterprises often use a WAN to connect its subsidiaries, branches and representative offices … anywhere in the world to serve the purpose of exchanging data back safely and fast! To be able to operate and deploy a WAN network, the device is indispensable here so router, the router has an important role in enterprise networks, it’s like the main backbone for all connections concentration of both models connect LAN and WAN.
Such a device would be constructed ROUTER how, how much, the router will operate and how the current market is best ROUTER:
ROUTER is composed of components such as the CPU – MAIN – RAM – FLASH – NVRAM – ROM connector …. Here I’m just making the most common structure should only refer CPU – MAIN – RAM – FLASH – connectors …
The CPU is a processor in charge of the implementation of the operating system commands such as system boot, routing, control the network interface. In large ROUTER types may have multiple CPUs
MAIN: the electronic circuits, connectors and signal transmission to the RAM chips – FLASH ..and contains connectors
RAM is a data memory of the router, which is used to store the routing tables, providing memory for fast switching, running configuration files and provides queues for the data packets are ready.
FLASH memory is also one of the router data transmission speed but ultrafast, FLASH is used to store the entire operating system software of the router, the default each time retrieving or every time you reboot the router will find systems FLASH operating in order to run
PORT CONNECTORS: ROUTER with the following ports: LAN – WAN – USB – SERIAL CONSOLE / AUX, …
ROUTER best on the market and is often referred to CISCO, CISCO was dubbed the Prince of routing features, however, due to high cost customer segment of small and medium almost skipped the favor for for it though Cisco has launched another appeal in this segment is the CISCO SMB devices but it seems this move was not really attract consumers.
