DHCP is a network protocol that dynamically assigns IP addresses to devices on a network. DORA process involves Discover, Offer, Request, and Acknowledge stages.
DHCP Discover: Client broadcasts a request for IP address
DHCP Offer: Server responds with an available IP address
DHCP Request: Client requests the offered IP address
DHCP Acknowledge: Server confirms the IP address assignment
SSL handshake is a process where a client and server establish a secure connection by exchanging encryption keys and verifying identities.
Client sends a hello message to server with supported encryption algorithms
Server responds with its own hello message, including its certificate
Client verifies server's certificate and generates a pre-master secret
Both client and server use the pre-master secret to generate a un...
A personal computer communicates with a web application through a series of steps involving network protocols.

ARP (Address Resolution Protocol) is a protocol used for mapping an IP address to a MAC address.
ARP is used to resolve IP addresses to MAC addresses on a local network.
There are two main types of ARP: ARP Request and ARP Reply.
ARP Request is sent by a device to find the MAC address of another device with a known IP address.
ARP Reply is sent in response to an ARP Request, providing the MAC address of the requested IP ad...
I appeared for an interview in Mar 2024.
Types of ARP include ARP request, ARP reply, ARP probe, and ARP announcement.
ARP request is used to find the MAC address of a device on the network.
ARP reply is the response to an ARP request, providing the MAC address of the target device.
ARP probe is used to check if an IP address is already in use on the network.
ARP announcement is used to inform other devices on the network about a change in MAC address.
