Q28: Why do we use DHCP?
Ans.:Dynamic Host Configuration Protocol assigns dynamic IP addresses to network devices
Physical Layer: It provides the hardware means of sending and receiving data on a carrier, including defining cables, cards and physical aspects. Fast Ethernet, RS232, and ATM are protocols with physical layer components.
DataLink Layer: Data packets are encoded and decoded into bits.The data link layer is divided into two sublayers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sublayer controls how a computer on the network gains access to the data and permission to transmit it. The LLC layer controls frame synchronization, flow control and error checking.
Network Layer: provides switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node.
Transport Layer: Provides transparent transfer of data between end systems, or hosts
Session Layer: This layer establishes, manages and terminates connections between applications.
Presentation Layer: It is used to present data to the application layer (layer 7) in an accurate, well-defined and standardized format.
Application Layer: the application layer as the user interface responsible for displaying received information to the user.
