OSI and TCP/IP models are networking models that define how data is transmitted over a network.

• OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, Application

• TCP/IP model has 4 layers: Network Interface, Internet, Transport, Application

• OSI model is theoretical while TCP/IP model is practical and widely used

• OSI model helps in understanding how data flows in a network, while TCP/IP mod...read more

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

• DHCP assigns IP addresses to devices on a network

• It helps in managing and organizing IP addresses efficiently

• DHCP reduces the need for manual configuration of network devices

• DHCP lease time determines how long an IP address is assigned to a device

• Example: When a new device connec...read more

VLAN, STP, VTP, and EtherChannel are networking concepts used to manage and optimize network traffic.

• VLAN (Virtual Local Area Network) divides a physical network into multiple virtual networks to improve performance and security.

• STP (Spanning Tree Protocol) prevents loops in Ethernet networks by blocking redundant paths.

• VTP (VLAN Trunking Protocol) manages VLAN configurations across a network to ensure consistency.

• Ethe...read more

IP addressing is a method used to assign unique numerical labels to devices on a network, while subnetting involves dividing a network into smaller subnetworks.

• IP addressing is used to uniquely identify devices on a network using a series of numbers separated by periods (e.g. 192.168.1.1).

• Subnetting involves dividing a larger network into smaller subnetworks to improve performance and security.

• Subnet masks are used to ...read more

DNS stands for Domain Name System, which translates domain names to IP addresses.

• DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to IP addresses (like 172.217.3.206).

• It helps users access websites and other online services by resolving domain names to their corresponding IP addresses.

• DNS also helps in email delivery, ensuring that emails are sent to the correct mail ...read more

Routing is the process of selecting the best path for network traffic to reach its destination.

• Routing involves determining the optimal path for data packets to travel from the source to the destination.

• Routers use routing tables to make decisions on how to forward packets.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Examples of routing devices include routers and layer 3...read more

A switch is a networking device that connects devices within a local area network (LAN) and forwards data packets between them.

• Switch operates at the data link layer of the OSI model

• It uses MAC addresses to forward data to the correct destination

• Switches improve network performance by reducing collisions and segmenting traffic

• Examples: Cisco Catalyst switches, Juniper EX Series switches
