ARP CACHE Meaning and
Definition
-
ARP cache, short for Address Resolution Protocol cache, refers to a type of memory storage used in computer networks to efficiently map network addresses to physical addresses. In the context of TCP/IP (Transmission Control Protocol/Internet Protocol) networking, the ARP cache is a table or database that stores the associations between IP addresses and MAC (Media Access Control) addresses.
The ARP cache acts as a crucial component of the ARP protocol, which enables communication between devices on a local area network (LAN). When a device wants to send data to another device on the same network, it needs to know the MAC address of the target device. The ARP cache allows devices to maintain a record of recent ARP requests and responses, preventing the need for repetitive ARP broadcasts.
The ARP cache typically stores entries consisting of IP addresses, corresponding MAC addresses, and a timestamp indicating the time when the association was last updated. Whenever a device sends an ARP request, it checks the ARP cache to determine if it already possesses the required information. If a match is found, the device can directly retrieve the MAC address from the cache instead of broadcasting an ARP request.
The ARP cache plays a crucial role in enhancing network efficiency by reducing network traffic and minimizing latency in address resolution. However, it should be noted that the entries in the ARP cache have a limited lifespan and can become outdated over time. Therefore, regular updates and refreshing of the ARP cache are essential to ensure accurate mapping of IP addresses to MAC addresses.

Etymology of ARP CACHE
The term "ARP cache" is derived from the combination of two concepts: Address Resolution Protocol (ARP) and cache.
1. Address Resolution Protocol (ARP): ARP is a network protocol used to map an IP (Internet Protocol) address to a physical (MAC) address on a local network. When a device wants to communicate with another device on the same network, it needs to know the MAC address of the destination device. ARP enables this mapping by sending a broadcast message to all devices on the network, requesting the MAC address associated with a specific IP address. The device with the matching IP address responds, and the requesting device updates its ARP cache with the corresponding MAC address.
2. Cache: A cache is a temporary storage area that stores frequently accessed or recently used data.
