DHCP stands for Dynamic Host Configuration Protocol. It is a network protocol that automatically assigns IP addresses to devices.

• DHCP is used to simplify network administration by automatically assigning IP addresses to devices

• It allows devices to join a network without manual configuration

• DHCP servers can also assign other network configuration information such as subnet mask, default gateway, and DNS server addresses

DNS stands for Domain Name System. It is a system that translates domain names into IP addresses.

• DNS is like a phonebook for the internet

• It helps to locate websites by translating domain names into IP addresses

• DNS servers store information about domain names and their corresponding IP addresses

• DNS can also be used for email routing and other internet services

A tree is a perennial plant with a single stem or trunk, supporting branches and leaves.

• Trees are important for the environment as they absorb carbon dioxide and produce oxygen.

• They provide shade, shelter, and food for animals and humans.

• Trees can be classified as deciduous or evergreen based on their leaves.

• Examples of trees include oak, maple, pine, and palm trees.

A server is a computer program or device that provides functionality to other programs or devices, called clients.

• A server is designed to manage network resources.

• It provides services to clients over a network.

• Examples include web servers, email servers, and file servers.

• Servers can be physical or virtual machines.

• They often have more processing power, memory, and storage than client devices.

Kerberos is a network authentication protocol used to provide secure communication over the internet.

• Kerberos uses a ticket-granting server to authenticate users and grant access to network resources.

• It uses symmetric key cryptography to ensure secure communication between the client and server.

• Kerberos is commonly used in enterprise environments to provide single sign-on functionality.

• It was developed by MIT and is no...read more

Subnetting is the process of dividing a network into smaller subnetworks.

• Subnetting helps in efficient utilization of IP addresses.

• It allows for better network management and security.

• Subnetting is done by borrowing bits from the host portion of an IP address.

• CIDR notation is used to represent subnet masks.

• Example: 192.168.1.0/24 represents a network with 256 IP addresses.

Active Directory is a Microsoft service that manages network resources and user permissions.

• Centralized database for managing network resources

• Allows for user authentication and authorization

• Provides a hierarchical structure for organizing resources

• Enables group policy management

• Integrates with other Microsoft services like Exchange and SharePoint

OSPF (Open Shortest Path First) is a routing protocol used in IP networks.

• OSPF is a link-state protocol

• It calculates the shortest path to a destination using Dijkstra's algorithm

• It supports VLSM (Variable Length Subnet Masking)

• It uses a hierarchical network design with areas

• OSPF routers exchange link-state advertisements (LSAs) to build a topology database

• It uses cost as a metric to determine the best path

• OSPF is commo
