It converts the digital data into an analog signal over the telephone lines.īased on the differences in speed and transmission rate, a modem can be classified in the following categories:Ĭable is a transmission media used for transmitting a signal.In Client mode, the access point connects your wired devices to a wireless network. A modem is not integrated with the motherboard rather than it is installed on the PCI slot found on the motherboard.A modem is a hardware device that allows the computer to connect to the internet over the existing telephone line.Router splits the single network into two networks of 12 workstations each, reduces the traffic load by half. This increases the traffic load on the network. Suppose there are 24 workstations in a network generates a same amount of traffic. Performance: Router enhances the overall performance of the network.Reliability: If the server has stopped functioning, the network goes down, but no other networks are affected that are served by the router.Security: The information which is transmitted to the network will traverse the entire cable, but the only specified device which has been addressed can read the data.It determines the best path from the available paths for the transmission of the packet.A router forwards the packet based on the information available in the routing table.A router works in a Layer 3 (Network layer) of the OSI Reference model.It is used to receive, analyze and forward the incoming packets to another network. A router is a hardware device which is used to connect a LAN with an internet connection.Therefore, we can say that switch provides a direct connection between the source and destination. It determines the device to whom the message is to be transmitted. A Switch does not broadcast the message to the entire network like the Hub. Switch delivers the message to the correct destination based on the physical address present in the incoming message. The Switch contains the updated table that decides where the data is transmitted or not. A Switch contains more advanced features than Hub. SwitchĪ switch is a hardware device that connects multiple devices on a computer network. Nowadays, the use of hub is obsolete, and it is replaced by more advanced computer network components such as Switches, Routers. The process used by the Hub consumes more bandwidth and limits the amount of communication. All the devices will check whether the request belongs to them or not. Hub will broadcast this request to the entire network. When computer requests for some information from a network, it first sends the request to the Hub through cable. HubĪ Hub is a hardware device that divides the network connection among multiple devices. For example, laptop computer contains the wireless NIC. Wireless NIC: The wireless NIC contains the antenna to obtain the connection over the wireless network. Cables and connectors are used with wired NIC to transfer data. Wired NIC: The Wired NIC is present inside the motherboard. The MAC address is stored in the PROM (Programmable read-only memory). The MAC address or physical address is encoded on the network card chip which is assigned by the IEEE to identify a network card uniquely.It can support a transfer rate of 10,100 to 1000 Mb/s.NIC is a hardware component used to connect a computer with another computer onto a network. For example, the wireless network does not require a cable.įollowing are the major components required to install a network: NIC Depending on the type of network that we need to install, some network components can also be removed. Some important network components are NIC, switch, cable, hub, router, and modem.
