Computer Science

a device that requests services, files or resources from a server on a network

a computer that stores, manages and shares files, data and resources in a network

a type of network where each device (peer) can act as both a client and a server, sharing files and resources directly without a central server

Network basics

Types of network

Network hardware and MAC addresses

Network topologies

Wired networks

Wireless networks

Network addressing

Network performance

In this unit pupils will be develop their understanding of computer networks by looking at network models and the tasks performed by network hardware. They will discover the differences between wired and wireless transmission media and the factors that can affect the performance of a network.

Network fundamentals

a network where devices are designated as clients or servers

a network of personal devices that allows data to be exchanged within their immediate vicinity

a single network covering a single site, usually covering a small geographical area

two or more distinct networks connected together, usually covering a large geographical area

a device that manages the flow of data between computer networks

a device in a wired network that sends data only to the device that needs it

an address given to a network interface controller, used to uniquely identify devices on a local area network

the arrangement (usually physical) of a network where devices are connected through a central point

a network where all devices are connected to a single shared communication line that transmits data to every device on the network

a network where each device is connected to one or more others, allowing multiple data paths

a network where devices are connected using physical cables to transfer data

a common network cable made from twisted copper wires that transmits data using electrical signals

a high-speed network cable that sends data as pulses of light

a network that connects devices wirelessly using radio waves within a limited area

network protocols that allow devices to communicate over a local network using radio waves

a standard for wireless technology that is used for exchanging data over short distances

a unique number assigned to each device on a network, used to identify it and allow it to send or receive data

a server that works to resolve domain names to corresponding IP addresses

the maximum amount of data that can be transferred over a communication channel

the process where routers select the best path for data to travel across a network, using rules called routing protocols
