Network & networking refers to the practice of connecting computers and other devices to share resources and information.

• Network refers to a collection of computers and devices connected together to share resources and information.

• Networking involves the design, implementation, and management of these networks.

• Types of networks include LAN (Local Area Network), WAN (Wide Area Network), and WLAN (Wireless Local Area Net...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 eliminates the need for manual IP address configuration

• It allows devices to easily connect to a network and obtain necessary network settings

• DHCP servers lease IP addresses to devices for a specific period of time

• Commonly used in home and business networks to manage IP addre

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how data is transferred from one computer to another over a network.

• Each layer has specific functions and interacts with adjacent layers.

• Examples of layers include Physical layer, Data Link lay...read more

• The OSI model stands for Open Systems Interconnection model

• Each layer has specific functions and interacts with adjacent layers

• Layers include Physical, Data Link, Network, Transport, Session, Presentation, and Application

• Data is passed down through the layers on the sending device and up through the layers on the receiving device

There are mainly three types of networks: LAN, WAN, and MAN.

• Local Area Network (LAN) - used to connect devices within a limited area like a home, office, or school.

• Wide Area Network (WAN) - connects devices over a large geographical area, often using public infrastructure like the internet.

• Metropolitan Area Network (MAN) - covers a larger area than a LAN but smaller than a WAN, typically within a city.

Topology refers to the arrangement of nodes in a network and how they are connected.

• Topology defines the physical or logical layout of a network.

• Common topologies include bus, star, ring, mesh, and hybrid.

• Each topology has its own advantages and disadvantages in terms of cost, scalability, and fault tolerance.

APIPA stands for Automatic Private IP Addressing and is used when a device cannot obtain an IP address from a DHCP server.

• APIPA assigns a unique IP address to a device when it cannot connect to a DHCP server.

• It allows devices to communicate on a local network even without a DHCP server.

• APIPA addresses are in the range of 169.254.0.1 to 169.254.255.254.

• It is commonly used in small home or office networks where a DHCP se
