what is network in computer

their hierarchy. Put simply, a Local Area Network (LAN) is a group of computers and other devices that are connected together over a network and are all in the same location—typically within a single building like an office or home. A computer network can be categorized by their size. How does a computer network work Specialized devices such as switches, routers, and access points form the foundation of computer networks. Computer Network Topologies with computer network tutorial, introduction, features, types of computer network, components, cables and connectors, Router, Intranet, Modem, Uses Of Computer Network, Hub, Software and The computer with the neural network is taught to do a task by having it analyze training examples, which have been previously labeled in advance. Ethernet Cords Ethernet crossover cable eliminates the need for network switches or routers. Computer network helps you to share expensive software's and database among network participants The biggest drawback of installing computer network is that its initial investment for hardware and software can be costly for initial set-up The computer provides connectivity to a distant network or an automated system outside the host network node boundaries. On a single LAN, computers and servers may be connected by cables or wirelessly. In the past, some computer makers integrated internal dial-up modems into the computer. Networking should be done only when it is really required. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. Many computer users are familiar with the Ethernet cable, because that's what they plug into their computer or high-speed modem to connect to the Internet. So for. This hierarchy may be physical in the case of a wired network, or it may be virtual in the case of a wireless network. A socket is one endpoint of a two way communication link between two programs running on the network. Maintenance of computer network – The basic and foremost important role of the network engineer is the proper operation of data flow in the network. With network segmentation technology, a computer network is classified into subnetworks. They are responsible for a … A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A multitude of devices may connect to the network, including computers , laptops , smartphones , smart appliances, tablets , and video game consoles . A computer network is a set of computers, or nodes, that are connected by cables or connect wirelessly via radio waves. The computers on a network, also known as nodes, can share resources In addition, to add a computer to the network, we also have to adjust or change its configuration settings. The main advantages of this topology are better flexibility and scalability. Network Computer: A network computer is an inexpensive personal computer designed for a centrally-managed network -- that is, data are stored and updated on a network server -- and lacks a disk drive, CD-ROM drive or expansion slots. A computer network is a set of interconnected computers that are connected wirelessly or via cabling for the purpose of sharing media or data. A computer network is a set of computers that are connected together so that they can share information. Every computer on a network should be appropriately configured for its use.
