SUMMARY


In networking it means joining or linking devices such as computers.a local area network(LAN) is a collection of computers and other devices connected through some medium that transmits mostly data.advantage in networking management security is one of the advantage it often includes protections against viruses,hacking, and other threats that can come from both outside  and inside a company. and some advantage that come with networking are the amount of information given. that will not be enough to every problem and system that we use to retrieve the data maybe extremely slow.


TOPOLOGIES remain an important part of network design theory we can probably build a home or small business computer network without understanding the difference between a bus design and star design but becoming familiar with the standard topologies give me better understanding of important networking concepts like hubs,broadcast,and router.
