MAC

(1) Medium Access Control. In LANs, the sublayer of the data link control layer that supports

medium-dependent functions and uses the services of the physical layer to provide services to the logical

link control (LLC) sublayer. The MAC sublayer includes the method of determining when a device has

other attributes of all or part of the message are as they appear to be. (

IBM Glossary of Computing Terms

)

MAC address

The Media Access Control address is a unique 48-bit hardware address assigned to every network interface

card. Usually written in the form 01:23:45:67:89:ab.

Management Information Base

When SNMP devices send SNMP messages to the management console (the device managing SNMP

messages), it stores information in the MIB.

Mbps

Megabits per second.

MBONE

See “Multicast Backbone” on page 13.

MD5

MD5 creates digital signatures using a one-way hash function, meaning that it takes a message and converts

it into a fixed string of digits, also called a message digest.

When using a one-way hash function, one can compare a calculated message digest against the message

digest that is decrypted with a public key to verify that the message hasn't been tampered with. This

comparison is called a "hashcheck."

MDI/MDIX

In cable wiring, the concept of transmit and receive are from the perspective of the PC, which is wired as a

Media Dependant Interface (MDI). In MDI wiring, a PC transmits on pins 1 and 2. At the hub, switch,

router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring is

referred to as Media Dependant Interface - Crossover (MDI-X). See “Auto-negotiation” on page 3.
