Computer Science

a global system of interconnected computer networks

a service provided via the internet that allows users to access and navigate linked content, such as webpages

Internet fundamentals

How data travels across the internet

Protocols

Network models

The TCP/IP model

Hosting services

Web technologies

Threats to networks

Network security

In this unit pupils will explore how data travels across the internet. They will explore how protocols define communication between devices and the purpose of common network protocols. They will investigate the risks to networks and the methods that can be used to protect a network.

The internet and web technologies

servers that work together to match domain names to the stored location of the webpage

a small part of a whole file that is transmitted over a network

a method of transmitting data across the internet using small packets of data

a set of rules used to allow devices to communicate with each other

a set of rules that protects data when devices communicate with each other

a set of rules that controls how data is sent over the internet such as how it is addressed

a seven-layer model that describes how different computer systems can communicate over a network

when data is packaged with additional information as it moves down through the layers of the network model

when data is received and unpacked by a device as it moves up through the layers of the network model

a level in a model that describes how data is transmitted across a network

a conceptual four layer model and set of protocols for internet communications

storing a website or an online service on a server, so it can be accessed over the internet

software hosted online and usually accessed via a web browser or app without needing to install it on your own device

when code runs on the user's device (the client)

when code runs on a web server and then the content is sent to the user’s browser

a program used by search engines to browse and collect information from websites

the process of improving how a website appears in search engine results

techniques used to trick users into giving away personal information by manipulating their behaviour or emotions

malicious software - a program designed to cause damage to computer systems, corrupt or change files, steal data or cause disruption to services

a system that filters network traffic to protect against unauthorised flows of data in or out of the network
