What is a router teach ICT?
A Router is a device that transfers data from one network to another in an intelligent way. It has the task of forwarding data packets to their destination by the most efficient route. Above: A domestic combined router / ADSL modem. In order to do this, the router has a micro computer inside it.
What is Ethernet teach ICT?
Ethernet is a computer networking protocol. In this protocol, all networked computers are connected together by a wire or channel. (The channel is often a type of radio link called “Wi-Fi”).
What is the role of the router GCSE?
A router can form a LAN by connecting devices within a building. It also makes it possible to connect different networks together. Homes and businesses use a router to connect to the internet. A router can often incorporate a modem within the hardware.
What is a WAP used for?
Wireless Application Protocol (WAP) is a specification for a set of communication protocols to standardize the way wireless devices, such as mobile phones and radio transceivers, can be used for internet access, including email, the web, newsgroups and instant messaging.
What is a hub Igcse?
Hub. A hub is a device that connects a number of computers together to make a LAN. The typical use of a hub is at the centre of a star network (or as part of a hybrid network) – the hub has cables plugged into it from each computer.
What is a LAN GCSE?
LANs. A local area network (LAN) is a network that is geographically confined to one building or site. Examples include networks employed by small businesses, small organisations, schools, colleges, universities and in homes.
What’s the primary purpose of a router?
A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.
Is a router an access point?
Key differences between wireless access points and wireless routers. Routers can serve either wired or wireless connectivity for several end-user devices, while an AP mainly serves wireless devices, such as phones, laptops and tablets. Essentially, an AP brings wireless capability to a wired network.
How does a router work Igcse ICT?
Routers send ‘packets’ of data between computers on different networks. Each data packet contains the IP address of the computer/network that the data is being sent to. The router will use the IP address to work out the best route in which to send the data to it’s destination.

What is a router BBC Bitesize?
Routers are one of the most commonly used connection devices. They are used to send data signals across the internet . Routers work by collecting knowledge of available routes to transmit data. They then determine the most suitable route for sending data. Routers are also commonly used in homes.
What is WAN in ICT?
A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.
What are the features of a router?
Features of Routers
- A router is a layer 3 or network layer device.
- It connects different networks together and sends data packets from one network to another.
- A router can be used both in LANs (Local Area Networks) and WANs (Wide Area Networks).
- It transfers data in the form of IP packets.
What is the importance of routing?
Routing is the hub around which all of IP connectivity revolves. At the simplest level, routing establishes basic internetwork communications, implements an addressing structure that uniquely identifies each device, and organizes individual devices into a hierarchical network structure.
What is a router in networking BBC Bitesize?
Routers. Routers are one of the most commonly used connection devices. They are used to send data signals across the internet. Routers work by storing the addresses of computers on the network. They then determine the most suitable route for sending data.
What is LAN and WAN in ICT?
LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings. WAN is a computer network that covers a broad area. For example, any network whose communications links cross-regional and metropolitan boundaries over a long distance.

The internet is a WAN. A network of bank cash dispensers is a WAN. A school network is usually a LAN. LANs are often connected to WANs, for example a school network could be connected to the internet.
What is purpose of router?
A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
