(Data Communication) is a task that involves managing hardware, software, firmware in networking.

A (Personal Area Network) is a computer network classification that can be discriminated into various types such as Client-Server, peer-to-peer or hybrid, depending upon its architecture.

A (Metropolitan Area Network) generally expands throughout a city such as cable TV network. Its span is bigger than Local Area Network and can be in a form of Ethernet or FDDI.

A classification of computer network which is, it is classified into client-server, hybrid, etc is (Computer Network)

A network LAN technology that provides speed up to 1000 mbits/seconds is the (Fast Ethernet) which is IEEE802.3ab standard over UTP using Cat-5 to Cat-6 cables.

A network type that is widely deployed on Web services using HTML linked pages and can be accessible by Web browser is the (Internet)

An (Ethernet) divides a single broadcast domain into multiple broadcast domain.

A network topology that each host are connected to two other machine creating circular network structure is (star topology).

A (mesh topology) is a host connected to one or more hosts which is a host has point-to-point connection with every other host and comes with a full and partially type.

A (daisy chain) topology is a design that contain more than one topology. This inherits merits and demerits of all incorporating topologies.

A device which is known as network interface card that is a component of a computer to connect Ethernet LAN is (RJ 45).

A (star) topology are connected to a central device using a point-to-point connection. That central device can be a switch which acts as single point of failure.

A (router) have routing table and can be classified in two types: Static and Dynamic.

A (switch) is a networking device that is capable of converting analog into digital signal and vice versa.

A networking device that is used to connect several dissimilar networks is a (Router). Usually a computer with multiple NIC.

A network cable type that has single-core or multi-core type is (FDDI). It has sheath, conductor, and insulation and mostly use of cable TV.

Most Ethernet LANs are made of this cable type. It has specification of color-coded pairs of insulated copper wires. It is a (FDDI)

A (Fiber optic cable) is not affected with Electro Magnetic Interference and Radio Frequency Interference.

A (SMF) optical cable supports much higher bandwidth and longer distance than the MMF cable.

A (splicer) is a tool use in creating network cable, specifically Ethernet cable which is use to lock pins in RJ 45 to the copper wires of twisted-pair cables.

An instrument to test the Ethernet cable if it is working or to see if the cable is done correctly is the (cable crimper).

A networking device with multiple ports ranging from 8 ports to 24 ports and uses packet switching technique to receive, store and forward data packets.

The part in a coaxial cable which protects the core or separate the braided-shield from the core.

A twisted pair cable which is more expensive and have additional plastic and metal shield to protect the cable from interference.

The (coaxial) cable has core, cladding, buffer and jacket and complete immune to EMI and RFI.

An ethernet cable type which is used to connect a router and a personal computer.

The (rollover) cable type is not responsible for transmitting data rather they only establish an interface with the devices.

A network cable type that used to connect not SIMILAR networking device over the network.

The network of networks is called (Local Area Network) which is the connection of computer worldwide.

(Computer network) may define both physical and logical aspect of the network. It is the arrangement with which computer systems are connected to each other.
