- 1what is the purpose of an NIC?The NIC's convert the data signals from the notes into data signals that can be transferred across the network.
- 2what is the purpose of an Router.Routers work by sending data between network [e.g over the internet]
- 3what is the purpose of an Hub.A device that connects nodes together not intelligent - data is sent to all nodes across the whole of the network.
- 4what is the purpose of an Switch.A device that connects nodes together
An intelligent device that can can send data to nodes that the data is intended for. - 5what is the purpose of an Wireless Access Point.Wireless Access Point the AP usually connects to a router [via a wired network] as a standalone device but it can also be an integral component of the router itself. an AP is differently from a hotspot which is the physical location where WI-FI access to a LAN is available.
- 6what is the purpose of a WAP?WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including e-mail, the World Wide Web, newsgroups, and instant messaging.
- 7describe a wan?A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).

- 8describe a lan?A local area network (LAN) is a network that connects computers and other devices in a relatively small area, typically a single building or a group of buildings. Most LANs connect workstations and personal computers and enable users to access data and devices (e.g., printers and modems) anywhere on the network.
- 9what is a computer network?A computer network or data network is a digital telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
- 10What are the advantages of a computer network?Advantages of computer networking. There are several distinct advantages to networking, including: ... Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.
- 11What are the disadvantages of a computer network?Disadvantages. Purchasing the network cabling and file servers can be expensive. Managing a large network is complicated, requires training and a network manager usually needs to be employed. ... Viruses can spread to other computers throughout a computer network.
- 12What devices are needed to produce a LAN?Network Adapter. A computer needs a network adapter to connect to a network. ...
Network Medium. Wired networks need cable. ...
Cable Connectors. ...
Power Supply. ...
Hub/Switch/Router. ...
Network Software. - 13What is the difference between a Hub and a Switch?Difference between a Ethernet hub, a switch, and a router. ... Ethernet hubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or even other networks. Each has two or more connectors called ports into which you plug in the cables to make the connection.
- 14What is the Internet?a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
- 15What is the World Wide Web?an information system on the Internet which allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another.
- 16What is the purpose of a Modem?WHAT IS THE PURPOSE OF A MODEM? Modem stands for MOdulator/DEModulator. A modem converts digital signals generated by the computer into analog signals which can be transmitted over a telephone or cable line and transforms incoming analog signals into their digital equivalents
- 17What is the purpose of an ISP?An Internet service provider (ISP) is an organization that provides services accessing and using the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.
