what is computer network in english?

A communication computer, two or more computers connected to each other for electronic communication information. In addition to computer hardware and communication technology, the communication system is critical in establishing an integrated interface that allows different types of devices to transmit information almost seamlessly. Two well -known architectures are ISO Open Systems Interconnection (OSI) and IBM’s System Network Architecture (SNA).

The two types of network connections are local area networks (LANs) and broadband networks (WANs). LANs connect computers and external devices to a limited physical environment, such as a business office, laboratory, or college, using networks (wires, Ethernet cables, fiber optics, Wi-Fi) to quickly transfer data. A typical LAN consists of two or more computers, a printer, and a high-capacity disk storage device called file system, which gives all computers on the web access to a common set of files. LAN operating system software that defines inputs and provides instructions to device networks allows users to communicate with each other; distribution of printers and warehouses; and at the same time enter scheduled process actions, data, or programs (set instructions). LAN users can also use other LANs or connect to WANs. LANs with a similar image shape are connected by “bridges” as a conceptual interface. LANs and different architectures are associated with “gateways” that convert information during the transition between systems.

 

What do you really know about the internet?

You are currently using it. However, you need to take this test to find out what you really know about the internet.

Wan is connected to computers and small networks in large networks in public spaces, covering different continents. Computers can be connected by wire, cable, or satellite, but their users usually access communications through a modem (a device that allows computers to communicate over telephone lines). The largest WAN is the Internet, a collection of networks and gateways that connect billions of computer users on every continent.
