What is the application of computer network?

Applications of Computer Networks. A network is a collection or set of computing devices connected to one another to establish communication and also share available resources. A network will comprise of software and hardware devices. They help us to transfer data from one point to another within the network.

What are the advantages of computer network?

Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money. Sharing a single internet connection – it is cost-efficient and can help protect your systems if you properly secure the network.

Where are computer networks used?

A LAN can be connected to a WAN using a router. A home area network (HAN) is a residential LAN used for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, such as printers and mobile computing devices.

What are the different types of computer networks?

Common types of area networks are:

  • LAN – Local Area Network.
  • WAN – Wide Area Network.
  • WLAN – Wireless Local Area Network.
  • MAN – Metropolitan Area Network.
  • SAN – Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network.
  • What is a network and types of network?

    A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. Two very common types of networks include: Local Area Network (LAN) Wide Area Network (WAN)

    What do you mean by computer network?

    A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server. The Internet itself can be considered a computer network.

    What is the backbone of a computer?

    A backbone is a part of computer network that interconnects various pieces of network, providing a path for the exchange of information between different LANs or subnetworks. A backbone can tie together diverse networks in the same building, in different buildings in a campus environment, or over wide areas.

    What are the advantages of a network?

    Advantages and disadvantages of networks

  • Sharing devices such as printers saves money.
  • Site (software) licences are likely to be cheaper than buying several standalone licences.
  • Files can easily be shared between users.
  • Network users can communicate by email and instant messenger.
  • How many types of networks are there?

    Video: Types of Networks: LAN, WAN, WLAN, MAN, SAN, PAN, EPN & VPN. There are so many different types of computer networks in existence, it can be hard to understand the differences between them, particularly the ones with very similar-sounding names.

    What is a WAN in computer terms?

    A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.

    What is a server on a computer?

    In a technical sense, a server is an instance of a computer program that accepts and responds to requests made by another program, known as a client. Less formally, any device that runs server software could be considered a server as well. Servers are used to manage network resources.

    What are the basic components of a network?

    Identify the purpose, features, and functions of the following network components:

  • Hubs.
  • Switches.
  • Bridges.
  • Routers.
  • Gateways.
  • CSU/DSU.
  • Network interface cards (NICs), ISDN adapters, and system area network cards.
  • Wireless access points (WAPs)
  • What is network architecture in computer networks?

    Network architecture is the design of a communication network. It is a framework for the specification of a network’s physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats use.

    What is the network security?

    Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Networks can be private, such as within a company, and others which might be open to public access.

    What are the different types of network topology?

    Learn about the different types of network architecture.

  • Network Topology. Computers in a network have to be connected in some logical manner.
  • Bus. Bus topology uses one main cable to which all nodes are directly connected.
  • Star.
  • Ring.
  • Mesh.
  • What is Network Application Services?

    In computer networking, a network service is an application running at the network application layer and above, that provides data storage, manipulation, presentation, communication or other capability which is often implemented using a client-server or peer-to-peer architecture based on application layer network

    What is the meaning of multiplexing?

    Multiplexing (or muxing) is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal; the receiver recovers the separate signals, a process called demultiplexing (or demuxing).

    What is mean by LAN?

    A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment.

    What do you mean by network topology?

    A network topology is the pattern in which nodes (i.e., computers, printers, routers or other devices) are connected to a local area network (LAN) or other network via links (e.g., twisted pair copper wire cable or optical fiber cable). There are four principal topologies used in LANs: bus, ring, star and mesh.
