Star topology is an arrangement of the network in which every node is connected to the central hub, switch or a central computer. The central computer is known as a server, and the peripheral devices attached to the server are known as clients. Coaxial cable or RJ-45 cables are used to connect the computers.
This technique of transferring the information from one computer network to another network is known as switching. Switching in a computer network is achieved by using switches. A switch is a small hardware device which is used to join multiple computers together with one local area network (LAN). Network switches operate at layer 2 (Data link ...
The way in which data is transmitted from one device to another device is known as transmission mode. The transmission mode is also known as the communication mode. Each communication channel has a direction associated with it, and transmission media provide the direction. Therefore, the transmission mode is also known as a directional mode.
The transport layer is a 4 th layer from the top. The main role of the transport layer is to provide the communication services directly to the application processes running on different hosts. The transport layer provides a logical communication between application processes running on different hosts. Although the application processes on ...
If the host wants to know the physical address of another host on its network, then it sends an ARP query packet that includes the IP address and broadcast it over the network. Every host on the network receives and processes the ARP packet, but only the intended recipient recognizes the IP address and sends back the physical address.
Computer Network MCQ. 1) Which of these is a standard interface for serial data transmission? ASCII. RS232C. 2. Centronics. Show Answer. Workspace. 2) Which type of topology is best suited for large businesses which must carefully control and coordinate the operation of distributed branch outlets?
Routing is performed by a special device known as a router. A Router works at the network layer in the OSI model and internet layer in TCP/IP model. A router is a networking device that forwards the packet based on the information available in the packet header and forwarding table. The routing algorithms are used for routing the packets.
