Network Cable - Network Cable is one of the important part for computer networking. The most common network cables are Category 3, Category 5 and Category 5e. Category 3 cable works on 10BaseT network(10Mbps), Category 5 cable works on 100BaseT network (100Mps) and Category 5e Cable works on Giga Network (1000Mbps). They all use the same type of connector called "RJ45", which is the standard from IEEE(Institution of Electronical and Electronic Engineering). The cable has to designed to refuse interference and protect the internal wire. Since network cable is one of the very important medium in computer networking, the material inside the cable will affect the speed and reliable of the network, the plastic cover of the cable will affect the interference between cable to cable, the connection will affect the speed and reliable, and the duration will strongly affect the time require to repair your network, therefore, picking the right cable is one of the very important part in computer networking.
Network Adapter / Controller - Network Adapter is a piece of device or hardware which stay inside your computer, though a cable or wireless to connect to the router, switch or hub. A network adapter can be internal hardware card (PCI/ISA) or external (connect by USB/SERIAL port). Network Controller nowadays refer to a stronger, more stable hardware networking device use to connect by network server. A network controller works more faster, stable and reliable on it's IO(Input and Output compare to regular network adapter and it can support multiple type of networking standard and networking cable.
Network Router - Network Router is the device used to connect your computer network together. It buildin a processor to organized, protect and process data inside your network. Nowadays, many networking manufacture buildin DSL/Cable capability into network router and called them "DSL/CABLE Router", the most imporatant job for this kind of routers is perform internet connection sharing. But traditionally, router is used to connect and re-organized all the passthough data so that your internal network can understand the external network and vice versa. In addition, a traditional router understand all the computer behind it and can provide useful information when data arrived to the router. Furthermore, a router can also configurate firewall, policy and a lot more.
Software - The programs which user used to perform their task (not computer hardware) and directly communicated to the user.
Network Switch and Hub - Network Hub is the device used to connect your computer network together. It work just like a wire connector and it share a common "Medium" to communicate between each other. In the other words, in a Hub, only 2 computer can communication simultaneously. Network Switch work exectly like a Network Hub except all computers in the network can communicate simultaneously (in the networking point of field. The exception is, if one computer is already communicating to the other computer, and at the same time the third computer want to join in, then the third computer need to wait).
Power Supply / UPS - Power Supply is the component in the computer system which responsible to supply power to you system. It usually connect directly to your AC wall plug. UPS (Un-interrupted Power Supply) is the other device which usually external from your computer system. It protect the power breakdown in any reason. Usually it will store from 2Min - 2hours or power for your computer system (depends on the voltage used by your computer), so that you have enough time to shutdown your computer and minimize the damage to your computer system. Some of the software can even communicate to your UPS system and you can set the shutdown time when it detect your UPS is run out our power. It happens to be very useful and common for server environment.
