KWETNRO NETWORK LOGOOYTP TOPOLOGY TEKSCAP PACKETS UYOLTA LAYOUT NETWORK TOPOLOGY NETWORK TOPOLOGY A network topology refers to the layout of the computers and devices in a communication network. NETWORK TOPOLOGY The three basic network topologies are star, bus and ring. Most networks, including the internet, use the combinations of these basic topologies. STAR TOPOLOGY All the computers and devices on a star network connects to a central device. This central device may be a hub or a switch. • Any devices or computers connected to a network is called a node. • All the data that has been transmitted from one node will pass through the central device before reaching the other node. • Nodes can be added or removed from the network with little or no disruption to the entire network. • Star network are fairly easy to install and maintain. What will happen if a node or the central device fails on a star network? If one node fails, only that node is affected. The other nodes continue to operate normally. However, if the central device fails, the entire network is inoperable until the device is repaired. BUS TOPOLOGY The bus has a single central cable (physical cable) to which all computers and other devices connected. • It transmits data, instructions and information in both directions. • Bus network are cheap and easy to install. • Computers and devices can be attached or detached at any point on the bus. • Failure of one device usually does not affect the rest of the bus network. • What • It transmits data, instructions and information in both directions. • Bus network are cheap and easy to install. What is the greatest risk to a • Computers and devices can be bus network? attached or detached at any point on If the bus itself become the bus. inoperable, the network remains inoperable until the bus is back • Failure of one device usually does not in working order. affect the rest of the bus network. • What RING TOPOLOGY On a ring network, a cable forms a closed loop (ring) with all computers and devices. • Data is being transmitted from one device to other around the entire ring in one direction. • If one computer on a ring network fails, the entire network could stop functioning. DIRECTION: Read each statement below carefully. Write T if the statement is true. Supply the correct word for the underlined word if the statement is false. Use the group of words below for your answer. 1. Network is a collection of computers and devices connected together so that they can exchange information or share resources. 2. A data package is a unit of data made into a single package that travels along a given network path. Data package are used in Internet Protocol (IP) transmissions for data that navigates the Web, and in other kinds of networks. _________3. The three basic network topologies are star, mesh and ring. _________4. All of the computers and devices on a bus network connects to a central device. This central device may be a hub or a switch. 5. If one node fails in a star network, only that node is affected. The other nodes continue to operate normally. MULTIPLE CHOICE 1.
