NAME: SHABA OLUWATOSIN DEPARTMENT: MEDICINE AND SURGERY COLLEGE: MEDICINE AND HEALTH SCIENCES COURSE: GST 115- INTRODUCTION TO I.C.T ASSIGNMENT 1- CONNECTIVITY HARWARE DATE: NOVEMBER 11th, 2016. Connectivity hardware is the hardware that allows computer to be physically connected to different types of networks. In other words, it refers to those physical components of the computer system that allow it to connect to a network. Some examples of connectivity hardware include: Connectors, Network Interface Card (NIC), Repeaters, Hubs, Routers, Bridges, Brouters, Modems, Gateways, Channel Service Units etc. Connectors refer to those things found at the end of cables. They are used to terminate cables so that they can be connected to the NIC or any other network component. Network Interface Cards are expansions boards either built into the computer system or connected to it via expansion slots. They are used to connect the computer system to a network, and provide the physical, electrical and electronic connections to the network media. Repeaters are network devices that are use to replicate signals as they weaken while travelling across the network. Hubs are the central points of connections in networks. They enable network connections to accommodate more systems. Every device in the network connects directly to the hub through a single cable. Any transmission received on one port will be rebroadcast to all the other ports in the hub. So, if one station sends it, all the others receive it, but only the intended recipient listens to it. Routers are intelligent devices used to connect multiple and unrelated networks into a single internetwork. Once connected, the router, as an intelligent device, selects the best way to get network data to its destination based on the performance data that it gathers from the network itself. Bridges are used to connect two or more different Local Area Networks (LANs) together so as to keep traffic at a minimum on both sides of the bridge. Traffic is allowed to pass through the bridge only if the transmission is intended for a station on the opposite side. A Brouter is a combination of a bridge and a router. As such, it can carry out the functions of both devices; keeping traffic at a minimum, while effectively modulating data reception and transfer. Modems, otherwise known as Modulator/ Demodulators, are common network devices that are used to transmit data over phone lines, by converting the sent computer data signals to analog then back again. Gateways in network hardware are any hardware and software combination that connects dissimilar network together. Gateways are the most complex of network devices because they perform translations if multiple versions of computer network to enable all the networks to communicate with each other. Channel Service Units are devices that act as buffers between Local Area Networks (LANs) and the more public Wide Area Networks (WANs) to ensure that signals placed on the public lines are properly formed for the network.

On the other hand, UNIX is a more professional-user geared operating system as it cannot be used unless you have a basic knowledge of programming language. It is an independent operating system designed mostly for mainframes, servers and workstations. It was used as the basis of the MAC-OS and it cannot be freely distributed.
