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.
