3.Examine how Network Interface Card works.?
Ans:
NIC works on the physical layer and the data-link layer. Actually, NIC collects the data from the computer and sends it to the transmission Channel. It acts as a middleman between your computer and the data network. It is responsible to exchange the computer's data with a network.
4.What is High Level data link control?
Ans:
High-Level Data Link Control is a bit-oriented code-transparent synchronous data link layer protocol developed by the International Organization for Standardization. The standard for HDLC is ISO/IEC 13239:2002. HDLC provides both connection-oriented and connectionless service
5.List the difference between IPv4 and IPv6.?
Ans:
IPv4 IPv6
IPv4 has a 32-bit address length . IPv6 has a 128-bit address length
It Supports Manual and DHCP address configuration .
IPv6- It supports Auto and renumbering address configuration
In IPv4 end to end, connection integrity is Unachievable In.
IPV6- IPv6 end to end, connection integrity is Achievable
6.Define the function of a Router. ?
Ans:
A router receives and sends data on computer networks. Routers are sometimes confused with network hubs, modems, or network switches. However, routers can combine the functions of these components, and connect with these devices, to improve Internet access or help create business networks.
7.What is a Port?
Ans:
In computer networking, a port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service
8.Define Stream control Transmission Protocol. ?
Ans:
The Stream Control Transmission Protocol is a computer networking communications protocol in the transport layer of the Internet protocol suite
9.Identify the Port number of HyperText Transfer Protocol and Telnet. ?
Ans:
Between the protocols User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), there are 65,535 ports available for communication between devices.
Ans:
The File Transfer Protocol is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server
