The nodes (like computers, switches, and modems) are the sources of generating and transmitting data. Then the link (a transmission media) is used to bond among the nodes. By following the protocols, the nodes will transfer and receive data via connections. computer network architecture defines the design associated among these physical and logical...
It allows you to share resources such as printers, scanners, etc.You can share expensive software and database among network users.It facilitates communications from one computer to another computer.It allows the exchange of data and information among users through a network.Local Area Network (LAN)Metropolitan Area Network (MAN)Wide Area Network (WAN)As the name suggests, the local area network is a computer network that operates in a small area, i.e., it connects computers in a small geographical area like within an office, company, school, or any other organization. So, it exists within a specific area, e.g. home network, office network, school network, etc. A local area network may be a wire...
MAN is a high-speed network that spreads over a large geographical area such as a metro city or town. It is set up by connecting the local area networks using routers and local telephone exchange lines. It can be operated by a private company, or it may be a service provided by a company such as a local telephone company. MAN is ideal for the peopl...
WAN extends over a large geographical area. It is not confined within an office, school, city, or town and is mainly set up by telephone lines, fiber optic, or satellite links. It is mostly used by big organizations like banks and multinational companies to communicate with their branches and customers across the world. Although it is structurally ...
Performance
The performance is measured using transmit time and response time. The network quality will be improved if the performance of the network is high. Transmit time: The time taken to send a message from one device to another device is called as transmit time. Response time: The time passed from inquiry to response is called as response time. The total performance of the network depends on many factors, which include several users, Topology used in the network, and software and hardware used.
Reliability
The reliability in a network state whether the data delivery to the authorized and intended users was done correctly. The reliability of a network is one of the important factors for the delivery of data in the layers of the OSI model (Open System Interconnection).
Security
Network security involves the protection of data from unintended users' protection of data from damage and disruption. Security in a network avoids data breaches and data loss.
Topology:It refers to the physical arrangement and representation of all the nodes and components of the network. In general terms, Topology defines the structure of the entire network. The network topology is divided into five types. They are bus topology, star topology, ring topology, mesh topology, and tree topology.
Learn the basics of computer network, its definition, history, types, uses and advantages. Explore the topics of computer network such as LAN, WAN, VPN, IP address, subnetting, network security and more with examples and diagrams.
Learn the definition, types, work, terms, and concepts of computer networking. Explore the common network topologies such as LAN, WAN, VPN, and SAN with examples and diagrams. Find out how to connect devices using routers, switches, and other networking hardware.
- LAN(Local Area Network) Local Area Network is a group of computers connected to each other in a small area such as building, office. LAN is used for connecting two or more personal computers through a communication medium such as twisted pair, coaxial cable, etc.
- PAN(Personal Area Network) Personal Area Network is a network arranged within an individual person, typically within a range of 10 meters. Personal Area Network is used for connecting the computer devices of personal use is known as Personal Area Network.
- MAN(Metropolitan Area Network) A metropolitan area network is a network that covers a larger geographic area by interconnecting a different LAN to form a larger network.
- WAN(Wide Area Network) A Wide Area Network is a network that extends over a large geographical area such as states or countries. A Wide Area Network is quite bigger network than the LAN.
Jan 25, 2024 · Learn basic to advanced concepts of computer networks, such as data link layer, network layer, transport layer, application layer, network security and cryptography, compression techniques, etc. This tutorial covers various topics, protocols, devices, experiments and quizzes related to computer networks.
Learn about the OSI model, a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in another computer. The OSI model has seven layers, each with different functions and protocols, such as data link, network, transport, session, presentation and application layers.
Ring topology is a network setup often used in local area networks (LANs) and wide area networks (WANs). In this setup, computers are connected circularly using either RJ-45 network cables or coaxial cables, depending on the network cards in use. What's unique about a ring topology is that it doesn't require a central hub to work.
