Types of computer networks according to their size?
Computer networks can be classified according to their size as follows:
- The local network (LAN), which is a group of computers that communicate with each other within a small geographical area, and the computers in this network belong to the same organization, and the local network is the simplest form of computer networks, and the speed of data transmission in it To 1 Mbps, and can reach 10 Gbps.
- The regional network (MAN), which is the network that connects several local networks within medium geographical areas that may reach several miles, and the regional network is usually linked through high-speed communication media; Such as optical fiber cables.
- The wide network (WAN), which is those networks that cover very large geographical areas, and the World Wide Web is one of the most famous examples of wide networks, and the speed of wide networks varies according to the different means of communication used.
Types of computer networks according to the method of connection?
Computer networks are divided according to the way they are connected into many different types, and among these types are the following:
- The star network: (Star Topology), which is the network in which computers are distributed around a central device, and data is communicated from one device to another through the network through the central device, and this network is not affected by the failure of any computer in it, but if the central device fails, then The entire network crashes.
- Linear network: (Bus Topology), which is the network in which all devices are connected through a single line of wires, and the linear network is considered one of the cheapest types of networks and the easiest in terms of adding any device across the network, and this network is completely disrupted if any cut occurs in Central cable.
- The ring network: (Ring Topology), which is in which computers are connected in the form of a closed-loop when a message is sent in this network, it passes through all the devices between the sender and the receiver.
