A business network will usually require a connection with more bandwidth than a home network. The term internet (with a lower case “i”) is used to describe multiple networks interconnected. When referring to the global system of interconnected computer networks or the World Wide Web, the term Internet (with a capital “I”) is used. LANs provide high-speed bandwidth to internal end devices and intermediary devices. LANs interconnect end devices in a limited area such as a home, school, office building, or campus. Wireless LAN – Similar to a LAN but wirelessly interconnects users and end points in a small geographical area.
Sharing of information is possible in host, switch and router in the network. To improve the QoS and performance, link aggregation is performed. Layer 2 typically occurs across switch port which can be either physical port or virtual ones managed by VLAN, Hot Standby Router Protocol and link. A VLAN is a logical connection that allows hosts to be grouped together in the same broadcast domain, so that packets are delivered only to ports that are combined to the same VLAN.
If you add the “Cisco” to your search phrase, you will find many topologies using similar icons to what you have seen in this chapter. Logical topology diagrams – Identify devices, ports, and addressing scheme (Figure 1-14). Topology diagrams are mandatory for anyone working with a network.
Now is the time when technology has changed the world scenario. Be it start ups or government offices, everything is digitalized. If you maintain a home computer network , create a document that describes the benefits diamond miner progressive automation that the network provides along with the difficulties that you have experienced. Include in your document a network topology, a detailed description of the type of network you have and the equipment you use.
