Defination Of Computer Network
In a memo, Dr. Robert M. Metcalfe named the networking method “Ethernet” after the huge coaxial cables that connected computers in buildings, reminding him of the “ether” concept. His task was to connect computers in a building with each other and with the world’s first Xerox laser printer. Ethernet enabled computers to send data packets over coaxial cables to communicate between them and the printer.
Transmission media, referred to in literature as physical media for connecting devices to a computer network, include electrical cables, fiber optics, and free storage space. In OSI models, software takes over the transmission medium defined as layer 1 or layer 2 (physical layer or data interface layer).
A network is a collection of computers, servers, mainframes, network devices, peripherals and other devices connected to each other to facilitate the exchange of data. A network consists of two or more computers connected to each other to exchange resources such as printers and CDs, files exchanged and electronic communication enabled. Computer networks can be connected by cables, telephone lines, radio waves, satellites, infrared beams, etc.
There are many different types of networks that are used by different people and organisations for different purposes. A network like the Internet, for example, connects millions of people around the world.
WAN (Wide Area Network, LAN, Local Area Network) – A local area network is a group of computers connected in a small area such as a building or office. It is used to connect two or more PCs via a communication medium such as twisted pair or coaxial cable. Local Area Network (LAN) is a network that connects computers in a restricted area.
Local networks can be expensive, but they can be built with low-cost hardware such as hubs, network adapters, Ethernet cables, etc. In a home network, a single router can provide both wired and wireless connections.
One of the disadvantages is that many cables are needed to form such a network. This type of network is more complex than a home network because it is considered to be a LAN and is restricted to a specific location.
There are two main network types: local area networks (LANs) and wide area networks (WANs). A local area network (LAN) connects computers and peripherals to a limited physical area such as a business office, laboratory or college campus by using connecting wire, Ethernet cable, fiber optic or Wi-Fi to transfer data. Computers connected to such a network are classified as servers or workstations.
A computer network is a group of computers that are connected to another computer to exchange information. The earliest examples of computer networks date back to the 1960s, but in the half century since they have come a long way. Computer networks can be used in many different ways, including many different types of networks.
A computer network is a collection of computer devices that are interconnected to share information and resources between a variety of users. Online search, email, audio and video sharing, online commerce, live streaming and social networks all exist in computer networks. A computer network, or simply a group of computers that share a set of common communication protocols for digital connectivity and resource sharing, is located on a provided network node.
Digital connections form a wide spectrum of telecommunications network technologies based on wired, optical, wireless and high frequency methods and can be arranged in a variety of network topologies. Network nodes can include PCs, servers, network hardware, and other specialized and universal hosts.
Each device on the network is associated with a unique device name, also known as host name. Type the hostname into the prompt in Administrator mode and press Enter to display it on your machine. This is the logical address (IP address) of the network or the address of the system on the network.
A computer network includes multiple devices and media that help communicate between two different devices; these devices are called network devices and include things like routers, switches, hubs, and bridges. Internetwork Internetwork is defined when two or more computers in a network (LAN, WAN, or computer network segment) are connected to devices configured with a local addressing scheme. The networking of several devices, also known as hosts, takes place via several ways of sending and receiving data and media.
Not a single LAN, but at least an extranet with at least one connection to an external network. Identifies the devices in the network and the connections to the network by assigning IP addresses.
Access point switches connect devices to the network via a cable. Switches connect computers, printers, servers and other devices in a network, whether at home or in an organization. Switch routers differ in several ways, but one of the most important differences is that they identify the end devices.
PCs are devices for developing personal areas of the network such as laptops, mobile phones, media players and playstations. Servers are not used for human operations, but provide services to other computers and their human users on the network. These services include printing, faxing, software hosting, file storage, sharing, texting, data storage and retrieval, full access control and security of network resources and many others.
A network, also known as a computer network, is the practice of carrying out and sharing data between nodes of a common media and information system. Distributed Computing uses the computing resources of a network to complete tasks. A network includes not only the design, construction and use of networks, but also management, maintenance and operation of network infrastructure, software and policies.
Introduction to Networking Learn how computer networks work, the architecture with which the network was designed, and how to keep it secure. Computer network solutions help companies improve traffic, keep users happy, secure the network and provide services.
A computer network consists of two or more computers connected by cable, WiFi or wireless to transfer, exchange and share data and resources. You can build a computer network with hardware (routers, switches, access points, cables) or software (operational systems, business applications, etc.
