Presentation

Internet

A massive network of networks made up of computers and electronic devices that use TCP/IP communication protocols.

World Wide Web (WWW)

A collection of multimedia web pages stored on websites that use the internet to access information from servers.

HyperText Mark-up Language (HTML)

A language used to design web pages and write http(s) protocols.

Uniform Resource Locator (URL)

Specifies the location of a web page, such as www.hoddereducation.co.uk.

Web browser

Software that connects to DNS to locate IP addresses and interprets web pages.

Internet Service Provider (ISP)

A company that allows a user to connect to the internet, usually charging a monthly fee.

Public Switched Telephone Network (PSTN)

Network used by traditional telephones for making calls and sending faxes.

Voice over Internet Protocol (VoIP)

Technology that converts voice and webcam images into digital packets to be transmitted over the internet.

Internet Protocol (IP)

Protocol that provides addressing to devices connected to the internet, using IPv4 or IPv6.

IPv4

An IP address format that uses 32 bits, allowing for approximately 4.3 billion unique addresses.

Classless Inter-Domain Routing (CIDR)

A method that increases the flexibility of IPv4 addressing by using a suffix to specify net and host ID bits.

IPv6

A newer IP address format that uses 128 bits, designed for more addresses than IPv4.

Sub-netting

The practice of dividing a network into smaller subnetworks to improve performance and security.

Private IP Address

An IP address reserved for internal network use behind a router.

Public IP Address

An IP address allocated by an ISP to identify the location of a device on the internet.

Domain Name Service (DNS)

A system that translates domain names to IP addresses, making it easier to access websites.

JavaScript

An object-oriented programming language used to enhance HTML pages, primarily on the web.

PHP

A hypertext processor; an HTML-embedded scripting language used for web development.

Packet Switching

A method of data transmission in which data is broken into packets and sent over various routes before being reassembled.

Zero Compression

A method used in IPv6 to shorten addresses by replacing groups of zeros with a double colon.

Cellular Networks

Networks that allow mobile devices to connect to the internet, using radio waves.

Geostationary Earth Orbit (GEO)

A satellite orbit that provides long-distance coverage, remaining fixed relative to a point on the Earth.

Medium Earth Orbit (MEO)

Satellites that are used for GPS systems, orbiting the Earth at a height that allows for regional coverage.

Low Earth Orbit (LEO)

Satellites used by mobile phone networks, providing shorter-distance coverage with faster data transmission.

What does the abbreviation ISP stand for?

ISP stands for Internet Service Provider.

What does TCP/IP stand for?

TCP/IP stands for Transmission Control Protocol/Internet Protocol.

What is the purpose of a URL?

A URL specifies the location of a web page.

What is a web browser?

A web browser is software that connects to the DNS and interprets web pages.

What technology is used for voice transmission over the internet?

Voice over Internet Protocol (VoIP) is used for voice transmission over the internet.

What do IPv4 addresses use for format?

IPv4 addresses use a 32-bit format.

What is sub-netting in networking?

Sub-netting is dividing a network into smaller subnetworks for improved performance and security.

What is the function of DNS?

DNS translates domain names to IP addresses.

What is the primary programming language used to enhance HTML pages?

JavaScript is the primary programming language used to enhance HTML pages.

What does CIDR stand for and what is its purpose?

CIDR stands for Classless Inter-Domain Routing, and it increases the flexibility of IPv4 addressing.
