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

company incorporates a Bus Topology for a three locations. Bus networks use a common backbone to connect all devices. This is done with a single cable (backbone) that functions as a common communication link that all devices either tap into or attach to individually. Below is an example of a Bus Topology. Ethernet bus topology is considered the easiest to install and maintain because of its simplicity. Kudler uses a 100Base ThickNet cable for its backbone. The Bus Topology is very effective when connecting

the devices connected to the LAN •ALL devices connected within a LAN can hear ALL the packets irrespective of whether the packet is meant for that device or not. It is possible for some unscrupulous node listening to data packets not meant for that. •Suppose, your organization has different departments. Using a traditional LAN, when any changes take place within the organization, physical cables and devices need to be moved to reorganize the LAN infrastructure. •A LAN cannot extend beyond its physical
