MAC Address


What do the first three octets mean in mac address?

The UAA, or Universally Administered Address, is the most commonly used type of MAC address. This address is assigned to the network adapter when it is manufactured. The first three octets define the manufacturer, while the second three octets vary and identify the individual adapter. All network adapter manufacturers have their own code, called the Organizationally Unique Identifier (OUI).

What is network adapter?

Definition: A network adapter interfaces a computer to a network. The term "adapter" was popularized originally by Ethernet add-in cards for PCs.Modern network adapter hardware exists in several forms. Besides traditional PCI Ethernet cards, some network adapters are PCMCIA devices (also know as "credit card" or "PC Card" adapters) orUSB devices. Some wireless network adapter gear for laptop computers are integrated circuit chips pre-installed inside the computer.Windows and other operating systems support both wired and wireless network adapters through a piece of software called a "device driver." Network drivers allow application software to communicate with the adapter hardware. Network device drivers are often installed automatically when adapter hardware is first powered on.A few network adapters are purely software packages that simulate the functions of a network card. These so-called virtual adapters are especially common invirtual private networking (VPN).Also Known As: NIC, LAN card


What is the unit of information called when a network adapter adds the source and destination MAC address to the segment of data before it is transmitted on the network?

What is the build in identifying address coded into the NIC?

The built-in identifying address coded into a Network Interface Card (NIC) is called a MAC address. It is a unique identifier assigned to the hardware by the manufacturer and is used to identify devices on a network. MAC addresses are typically 48 bits long and are displayed in hexadecimal format.


What are the components of a network card?

A network card, or network adapter as it is sometimes called, allows a computer to connect to a network of other computers. These devices will usually have both a physical layer and a data link layer. Ethernet devices will most often have an 8P8C socket where the network cable can be connected.


What is a mac address called?

Media Access Control address. This is the hardware/vendor set address of a Network Interface Card. The format is xx:xx:xx:xx:xx:xx With the first 3 hexadecimal digits specifying the manufacturer. Network routers and switches use this address to control traffic to a Network Interface card, it is often tied to a user assigned IP Address (b.b.b.b, 4 octets, usually decimal, 0-255 each).


What is an ID number assigned to the wireless network which allows two devices to validate with each other?

It's called "MAC address".

Physical and MAC addressing are found in the OSI layer 2?


Can you have a dynamic Mac address?

In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.


What is an alternate term for an adapter card?

adapter A device that allows one system to connect to and work with another. An adapter is often a simple circuit that converts one set of signals to another; however, the term often refers to devices which are more accurately called "controllers." For example, display adapters (video cards), network adapters (NICs) and SCSI host adapters perform extensive processing, but they are still called "adapters."
