mac vs ip addresses

IP Address

A unique number that identifies a network or device, commonly referred to as a host, connected to a network.

MAC Address

A unique, permanent number that is assigned to a specific device on a local network.

Address Resolution Protocol (ARP)

A protocol that maps MAC addresses to IP addresses.

Physical Addressing

Refers to MAC addresses, which are permanent and tied to the hardware of the device.

Logical Addressing

Refers to IP addresses, which are not permanent and can change based on the network the device is connected to.

Organizationally Unique Identifier (OUI)

The first few values of MAC addresses that represent the manufacturer.

OSI Model Layers

The layers of the OSI model where MAC and IP addresses function.

Networking

The practice of connecting computers and other devices to share resources and information.

Unique Number

A number that distinctly identifies a device or network in a system.

Device

An electronic machine that processes data and connects to a network.

Host

A device connected to a network that can send or receive data.

Network Interface Card

A hardware component that allows a device to connect to a network.

Permanent Number

A number that does not change regardless of the network connection.

Changing IP Address

The phenomenon where an IP address changes when a device connects to a new network.

Data Routing

The process of directing data packets from one network to another.

Phone Number Analogy

The comparison of IP addresses to phone numbers for connecting to specific locations.

Doctor's Appointment Analogy

The comparison of MAC addresses to doctor's names for identifying specific devices.

Multiple Networks

The existence of various networks within larger networks, similar to clinics within hospitals.

Cellular Devices

Devices that frequently change IP addresses due to their mobility.

Data Connection

The link established between devices for the purpose of data exchange.

Network Change

The action of a device connecting to a different network, resulting in a potential change of IP address.

Conflict Resolution

The process of addressing scheduling conflicts, similar to changing a doctor's appointment.

ARP Table

A table that notes which IP addresses match which MAC addresses, allowing for efficient routing of network communications.

Ping

A network utility used to test the reachability of a host on a network and measure the round-trip time for messages sent.

Network Communication

The process of transferring data between devices over a network.

Device Identification

The process of determining the specific device on a network using its IP and MAC addresses.

Broadcast

A method of sending data to all devices on a network simultaneously.

Logical IP Address

The address assigned to a device that is used for routing data across networks.

Physical Address

The MAC address that uniquely identifies a device on a local network.

Network Traffic

The amount of data moving across a network at any given time.

Device Response

The action taken by a device in reply to a request or communication from another device.

Network Issues

Problems that arise in a network that can disrupt communication and data transfer.

Contact List

An organized list of contacts that allows users to easily access and manage communication information.

Data Transfer

The process of sending and receiving data between devices on a network.

Correct Recipient

The intended device or user that should receive a specific piece of data in a network communication.

Device Availability

The state of a device being ready and able to receive communications or data.

Network Assignment

The process of allocating IP addresses to devices on a network.

Longevity of Addresses

The duration for which an IP address or MAC address remains assigned to a device.

Incorrect ARP Entry

An error in the ARP table that can lead to misrouting of data and communication failures.
