Loopback IP is a special IP address used to send data back to the same device for testing and troubleshooting purposes.

• Loopback IP address is 127.0.0.1 in IPv4 and ::1 in IPv6

• It is often used for testing network connectivity on a device without needing an external network

• Loopback IP is commonly used in troubleshooting network issues

Subletting is the act of a tenant renting out all or part of a rented property to another party.

• Subletting involves the original tenant renting out the property to a subtenant.

• The subtenant pays rent to the original tenant, who in turn pays rent to the landlord.

• Subletting may require permission from the landlord, depending on the terms of the lease agreement.

• The original tenant remains responsible for the lease agreement and any damages caused by the subtenant.

Protocol is a set of rules that governs the communication between devices in a network.

• Protocol defines the format, timing, sequencing, and error checking of data transmission.

• Examples of protocols include TCP/IP, HTTP, FTP, and SMTP.

• Protocols ensure that devices can communicate effectively and understand each other's data.

Topology refers to the arrangement of various elements in a network, including nodes and connecting lines.

• Topology defines how devices are connected in a network

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

• Each topology has its own advantages and disadvantages

• Examples: Bus topology - all devices connected to a single cable; Star topology - all devices connected to a central hub

A MAC address is a unique identifier assigned to network interfaces for communications on a network.

• MAC stands for Media Access Control.

• It is a 48-bit address typically written as six groups of two hexadecimal digits separated by colons or hyphens.

• MAC addresses are used to uniquely identify devices on a network.

• They are assigned by the manufacturer and are usually hardcoded into the network interface hardware.

• Example: 00:1A:2B:3C:4D:5E

Subnetmask is a 32-bit number used to divide an IP address into network and host portions.

• Subnetmask is used in conjunction with IP addresses to determine the network and host portions of an address.

• It is represented in decimal format (e.g. 255.255.255.0) or CIDR notation (e.g. /24).

• Subnetmask helps in routing packets to the correct destination within a network.

• It is essential for creating subnets within a larger network to manage traffic efficiently.

Firmware is a type of software that is embedded into hardware devices to control their basic functions.

• Firmware is a specific type of software that is designed to control the hardware it is embedded in.

• It is stored in non-volatile memory, such as ROM or flash memory.

• Firmware is responsible for booting up the hardware device and providing basic functionality.

• Examples of firmware include BIOS in computers, firmware in routers, and firmware in IoT devices.

Types of network cables include Ethernet cables, fiber optic cables, and coaxial cables.
