computer network, the cabling and the arrangement between the network devices and computers is known as, network topology. As the definition implies the name is loosely tied to the actual appearance the network. There are several topologies; three of the more known ones are Star, Bus, and Ring. The Star topology is a network that is connected through a central device and all the network devices; printers, computers, SAN’s and all other network devise. This topology is the most common network arrangement

1 Describe computer network types and standards. 1.1 The description distinguishes types of networks. Homogeneous Networks Homogeneous means similar, it is easy to administer and protect the homogeneous network configuration in networking. In a homogeneous network configuration, the similar operating environment is used to run the all systems. Same protocols are used to run the same operating environment and with the similar security attributes. A homogeneous network used a NIS+ master

Computer network components consist of 2 parts - the items that are to be connected and the equipment that connects them The equipment to be networked are those components that you want to be able to communicate with each other or hardware that you want to share A network is defined as a group of interconnected computers but it really is more than that. The connected computers communicate with each other and share resources on the network. Common resources include printers, disk storage, databases

Hierarchical star topology is where all computers are connected to a single, centrally located point. The central point is usually a hub of servers and switches located in the main equipment room. If there is a problem with the central hub then the network will not be able to work. It can bring the whole system down. By having everything centralize, it makes troubleshooting and reconfiguration simpler. It is usually a home networks that uses a hub or switch. Star Bus topology is the simplest

2.1.1 Network History The history of computer networking is complex. It has involved many people from all over the world over the past 35 years. Presented here is a simplified view of how the Internet evolved. The processes of invention and commercialization are far more complicated, but it is helpful to look at the fundamental development. In the 1940s computers were large electromechanical devices that were prone to failure. In 1947 the invention of a semiconductor transistor opened

Physical Network Unit 3 Assignment 1 Hierarchical Star – An optimal network-on-chip (NoC) topology, hierarchical star topology, that uses the star graphs as building blocks is presented for high-performance system-on-chip (SoC) Design. Its topological properties are compared with the topologies in the same category in terms of various performance metrics including diameter, cost, fault tolerance, fault diameter etc. It has been shown that the hierarchical star topology is an optimal NoC topology. Simultaneously

ICT PROJECT ON TOPOLOGIES. STAR TOPOLOGY. In the star network topology, there is a central computer or server to which all the workstations are directly connected. Every workstation is indirectly connected to every other through the central computer. Star networks are one of the most common computer network topologies. ADVANTAGES :- * Better performance: star topology prevents the passing of data packets through an excessive number of nodes. At most, 3 devices and 2 links are involved
