The MAC (Media Access Control) address of the network card is used in both Ethernet and Token-Ring networks and is essential for communication. What does MAC provide?
A.A logical address that identifies the workstation
B.A physical address that is randomly assigned each time the computer is started
C.A physical address that is assigned by the manufacturer
D.The logical domain address for the workstation
Answers
Answer:
C. A physical address that is assigned by the manufacturer
Explanation:
Answer:
(C). A Physical Address That Is Assigned By The Manufacturer
physical address, sometimes referred to as its MAC address, is given by its manufacturers and is 48 bits long. Each manufacturers only has about 16 million or so unique addresses to utilize before the manufacturer has to start repeating address information because this name is split up into two 24-bit portions.
Explanation:
An Ethernet or network connection across a network is uniquely identified by its media access control address (MAC address). In specifically, the majority of IEEE 802 networking, especially Ethernet, use it to differentiate between various network interface.
MAC addresses appear in the Media Access Control Standard sub-layer of the OSI model. Address space, physical address, and destroyed address are other names for a MAC address. Every network interface card (NIC) created has a producer or distributor who assigns MAC addresses. Most networking types use them, but unlike IP addresses, MAC addresses are static and cannot be modified. Using the IEEE requirements, a MAC address is generated.
Integrated within the NIC firmware, each MAC address is represented by a 12-digit hexadecimal notation that is made up of a six-digit manufacturer's organization unique identification accompanied by a randomized or serialized six-digit unique identity.
