TYPES OF CABLE

What Are The Types Of Cables?

A. Twisted Pair

 

 a cable consisting of two wires twisted around each other, used especially for telephone or computer applications.

 1. STP (Shielded Twisted Pair)

  

 a special kind of copper telephone wiring used in some business installations. An outer covering or shielded is added to the ordinary twisted pair telephone wires; the shield functions as a ground.

 2. UTP (Unshielded Twisted Pair)

 are widely used in the computer and telecommunications industry as Ethernet cables and telephone wires. In an UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources.

B. Coaxial

 

 Coaxial cable, or coax, is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. 

C. Fiber Optic

 Fiber optic cable is a high-speed data transmission medium. It contains tiny glass or plastic filaments that carry light beams. Digital data is transmitted through the cable via rapid pulses of light.

 And now, let's talk about the difference between Straight-Through Cable and Crossover Cable.

A Straight-Through Cable  

  

 Is a type of twisted pair cable that is used in local area networks to connect a computer to a network hub such as a router,

While a Crossover Cable 

 

 Is a type of Ethernet cable used to connect computing devices together directly. Unlike straight through cable, crossover cables use two different wiring standards: one end uses the T568A wiring standard, and the other end uses the T568B wiring standard. 

TYPES OF COMPUTER NETWORK

The types of network is a collection of two or more computers, as wells as other related devices, connected together so that information can be exchanged between or among them.

The types of network are PAN, LAN, MAN, and WAN this blog will show you how they work individually 

PAN (Personal Area Network)

PAN (Personal Area Network) is a computer network used to interconnect devices centered on an individual workplace. PAN can be used for connecting personal devices, which typically involve a mobile computer, a cell phone, and/or a handheld computing device such as a PDA. The network is used transfer files including email, calendar, digital photos, and music.




LAN (Local Area Network)

LAN (Local Area Network) is a type of where two to as such as much as hundreds of computers are connected with each other using a network sharing device known as a hub or switch to enable sharing of files, printers, and other resources.




MAN (Metropolitan Area Network)

MAN (Metropolitan Area Network) A MAN is a larger network than a LAN. It involves connecting several networks together that reside within a city, town, or metropolis. On a MAN, users may be several miles apart, but resources appear on the network just as if they were located within the same building. 





WAN (Wide Area Network)

WAN (Wide Area Network) Is a telecommunications network or computer network that extends over a large geographical distance/place. Wide area networks are often established with leased telecommunication circuits.

TYPES OF NETWORK TOPOLOGY

WHAT ARE THE TYPES OF NETWORK TOPOLOGY?

TOPOLOGY
-A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.

RING TOPOLOGY
-In the ring network topology, the workstations are connected in a closed loop configuration. Adjacent pairs of workstations are directly connected. Other pairs of workstations are indirectly connected, the data passing through one or more intermediate nodes.







STAR TOPOLOGY
In the star network topology, there is a central computer or server to which all the workstations are directly connected. Every workstation is indirectly connected to every other through the central computer.

MESH TOPOLOGY
The mesh network topology employs either of two schemes, called full mesh and partial mesh. In the full mesh topology, each workstation is connected directly to each of the others. In the partial mesh topology, some workstations are connected to all the others, and some are connected only to those other nodes with which they exchange the most data.






LINEAR BUS TOPOLOGY
Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. 



TREE TOPOLOGY
A tree topology joins multiple star topologies together onto a bus. In its simplest form, only hub devices connect directly to the tree bus, and each hub functions as the root of a tree of devices. 





HYBRID TOPOLOGY

  A hybrid topology is a type of network topology that uses two or more differing network topologies. These topologies include a mix of bus topology, mesh topology, ring topology, star topology, and tree topology.
