Basic Network Topology and Communication Media Computer Science Essay
The basics of computer networking include understanding network types, geos or topologies, conventions, gadgets such as hubs, routers and switches, and basic data transfer and security. Networking involves linking computing devices to share resources and access data across nearby and global organizations. 2. PHYSICAL and LOGICAL TOPOLOGY. There are “types” of network topology: Physical topology refers to the actual physical layout of the devices on the network. Logical topology refers to how data is, email, walky-talky etc. b. Full-duplex mode: Simultaneous two-way communication, side by side at the same time, with data flowing in both directions simultaneously. E.g. Telephone, chat etc. 2.a Computer Network: Computer network is defined as a physical and logical connection of two or more computers and devices. 1. Mesh Topology: Mesh topology is a type of network topology where every computer is connected to every computer. other computer on the network. It is the most fault-tolerant network topology because it has multiple connections. In a mesh topology, each computer is connected to the other computer via a point-to-point connection. If there are n, a single cable is used connecting all included nodes. Ring. Each device has exactly two adjacent devices for communication purposes. Star. All computers are connected via a hub. Gauze. The mesh topology has a unique network design where every computer in the network is connected to each other. Network Devices: Network devices, also called network hardware, are physical devices that allow hardware on a computer network to communicate and interact with each other. Because network topology • The topology of a network specifies the geometric arrangement of the network. • The entire physical structure of the cable or data transmission media workstations, nodes, routers, and gateways is called the physical topology. • The way or path that data flows through the network is called the logical one. Following are some hybrid network topologies: 1. Star-Wired Ring Network Topology. In a hybrid star wiring topology, a series of star topologies are connected by a ring topology as the. The advantages and disadvantages of the star network topology are mentioned below: Advantages of the star topology. The failure of one computer has no consequences for other computers in a network. Easy to solve. Easily add or remove the computer in a network. Hub can be easily replaced. Disadvantages of star topology. Performance of, Learn the difference between a star topology and mesh topology0: Topology explained2: advantages disadvantages2: network.
