Network cables

after a few days ago post about theNIC which is a component that converts data into electrical signals, so now I will discuss about the data that are Conductor cable network. network cable is divided into several types. that are: 1. Coaxial cable: probably a bit difficult to find a network that still uses this cable. because the coaxial cable used by a computer network with bus topology type. positions lined up the other end, if there is damage, it will disrupt the overall network. bus topology has several weaknesses that make the performance less effective. them if a server in the store at the end of the network and clientThere are 2 types ofcoaxial cable. that are: a. Thicknet b. thinnet 2. UTP (unshielded twisted pair): This cable has 8 wires in it that has a small role re spectively. role on the cable is determined by the RJ-45 connectors that connect to theNIC. This cable is suitable for star topology type that connects a computer to a switch or hub that terhubungn with another computer. This cable is used on any computer network at this time. because the star topology is very easy in the diagnosis of damage and easy to fix. and jka there is damage on one cable that connects the computer, it will not affect the overall computer network and This cable can deliver data up to 100 m. 3. STP (shielded twisted pair) STP (Shielded twisted pair) is a type of telephone cable that is used in some installations business. There is an additional wrapper for each pair cable ("twisted pair"). STP cable is also used for data networks, use on the IBM Token-Ring. Packaging can provide better protection against EMI interference. These cables are usually used in token ring topology. will however have some disadvantages. that: a. Expensive price b. At high frequencies, the balance down so it can not compensate for the emergence of "crosstalk" and signal "noise". 4. FO (Fiber Optic): Fiber Optic Cable is the latest cable technology. Made of optical glass. In the middle there is a cable glas filaments, called "core", and surrounded by a layer of "cladding", "buffer coating", the amplifier material, and protector luar.Informasi transmitted using light waves by converting electrical signals into light waves. The most used transmitter LED or laser. and has several benefits there are: a. Large bandwidth capacity (gigabits per second). b. Further transmission distance (2 to more than 60 kilometers). c. Immune to electromagnetic interference. Fiber Optic Cables are widely used in WAN networks for voice and data communications. The main obstacle in the use of fiber optic cable LAN is an electronic device that is still expensive. While the price of fiber optic cable itself is comparable with UTP LAN cable.
