CPU - Central Processing Unit in charge to run the commands in the operating system. Some functions such as dilaukan by the CPU: the system initialization, routing, and control the network
interface. Router CPU is a microprocessor.
RAM - RAM is used for routing table information, fast switching cache, which is the road configuration, and set the packet queue. In most routers providing RAM memory space to perform the function of the router. RAM logically divided into main processor memory and memory share the input / output (I / O). Memory share I / O is the share of the router interfaces for storage while the package. The contents of RAM will be lost if the router is switched off or restarted. RAM typically type dynamic random-access memory (DRAM) and can be upgraded by adding a memory module yan called dual in-line memory module (DIMM).
Flash - flash memory used to store the image of the IOS. Normally needed IOS router default of flash. Image can be upgraded by downloading a new image into flash. IOS could be too compressed or not. In most routers to copy the IOS into RAM ditansfer during the booting process. On the other Cisco IOS router may be able to run directly from flash. Installed in a single flash. SIMMs slot or a PCMCIA card that can be added or removed during the upgrade flash.
NVRAM - NVRAM used to store the startup configuration. At the same device can be used as EEPROM NVRAM function. On other devices used to as a flash for boot melaukan. The contents of the NVRAM is not lost meskipung router is switched off or restarted.
Bus - Most routers consists of system bus and CPU. system bus used for communication between the CPU and the interface or an additional slot. This bus transfer to and from the packet interface.
CPU bus is used to access storage media components of the router. This bus command and data transfer to or from memory address used.
ROM - ROM used to store permanent code diagnostic startup, which is known as the ROM monitor. The main task is to dignosa ROM hardware during booting and loading the router IOS from flash to RAM. Some routers, ROM can also be used as an alternative boot source. And can be upgraded by removing socketnya chip.
Interface - Interface of the router used to connect the connection to the outside. There are 3 types of interfaces: LAN, Wan and the console or auxiliary (AUX). LAN interface is usually one or several types of ethernet or token ring different. Each controller chip intreface has a function to connect the system to the media. LAN interface is usually a fixed or modular configuration.
WAN interfaces such as serial, ISDN and integrated CSU. Same with the LAN interface, it also has a controller chip. Wan interface can be either fixed or modular configuration.
Console or AUX port is a serial prot used for the configuration process. It is used as a terminal of the communication port on the computer through a modem.
Power Supply - power supply is used as a resource to operate the components in the router. Some routers may have more than one power supply.

LAN interface connects the router to the LAN media. WAN allows connection connected through the service provider to distant places or to the Internet. Types of connections may be serial or other WAN interface. With the type of the other WAN interface, an, external devices such as CSU is required to connect the router to the local connection service providers. With the type of other WAN, the router may also be connected directly to the service provider.
The function of port management is different from other connections. A common management interface is the console and auxiliary port using the serial ports with EIA-323 is used for asynchronous communication with the port on the computer.
The first time the router is used, no network is configured, so the router can not communicate with other networks. To set up the router to get connected to the network, the initialization and configuration required. It is necessary to roll-over cable is connected between the port management to a computer through terminal software emulating sperti HyperTerminal. After configuration, the router is ready for communication with the network.
Below, the steps to connect the PC to the router:
1. Configuring the PC terminal emulation with the parameters:
- COM port that is used
- Baud: 9600
- Data bits: 8
- No parity
- Stop bits 1
- No flow control
2. Connect the RJ-45 connector cable roll-over to the router console terminal
3. Connect the other end to terminal DB-9
4. Connect the terminal DB-9 female adapter to the PC

Connection to the LAN router interface
Generally connected to the router via the LAN interface Ethernet or Fast Ethernet. Router as a host that communicates with the LAN through a hub or switch. In this case a straight-through cable is used. For 10BASE-TX or 100BASE-TX requires Category 5 UTP cable or better.

WAN using a variety of technologies to create data connections in a wide geographic area. Communication via WAN typically uses lease lines from the provider, such as leased lines, circuit-switched and packet-switched.
WAN service type of customer premises equipment (CPE), the router as a DTE that is connected to the service provider through a DCE device typically uses a modem or CSU / DSU. This equipment is used to convert data from the DTE to a service provider supported WAN. And chances are the router interface used is a serial connection.
