What is the MAC address in networking?

A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

What type of addresses are used in network and data link layer?

The physical address is the unique hardware address that identifies an interface of a machine on a physical network such as a LAN. Physical addresses are used in the data link layer. A network address is a machine’s logical address on a network.

What is layer3 address?

The layer 3 address is a logical address. It will pertain to a single protocol (such as IP, IPX, or Appletalk). The layer 2 address is a physical address. It pertains to the actual hardware interface (NIC) in the computer.

What are the different types of addresses?


Type of IP AddressDescription
Public IPA public IP address is an address where one primary address is associated with your whole network.
Private IPA private IP address is a unique IP number assigned to every device that connects to your home internet network.

What are the three types of addresses in TCP IP?

TCP/IP supports three classes of Internet addresses: Class A, Class B, and Class C. The different classes of Internet addresses are designated by how the 32 bits of the address are allocated.

What are the Layer 3 protocols?

The protocols used in Layer 3 include:

  • Internet Protocols IPv4/v6.
  • Internet Control Message Protocol (ICMP)
  • Distance Vector Multicast Routing Protocol (DVMRP)
  • Internet Group Management Protocol (IGMP)
  • Address Resolution Protocol (ARP)
  • Internet Protocol Security (IPsec)
  • Routing Information Protocol (RIP)

What does the data link layer do in TCP IP?

The data-link layer identifies the network protocol type of the packet, in this instance TCP/IP. The data-link layer also provides error control and framing. Examples of data-link layer protocols are Ethernet IEEE 802.2 framing and Point-to-Point Protocol (PPP) framing.

What is the function of the data link layer?

Layer 2 of The OSI Model: Data Link Layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the physical layer.

Which is not a function of data link layer?

2. Which of the following tasks is not done by data link layer? Explanation: Channel coding is the function of physical layer. Data link layer mainly deals with framing, error control and flow control.

What is LLC and MAC?

The data link layer (Layer 2) of the OSI model actually consists of two sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The MAC sublayer controls device interaction. The LLC sublayer deals with addressing and multiplexing.

What is a function of the data link layer Cisco?

The data link layer does the following: Transmits the data on the physical medium. Routes the data locally on the physical network medium. The data link layer uses physical addresses assigned to each physical network device in the local network to route data from one physical device to another.

What is LLC networking?

The logical link control (LLC) is the upper sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It acts act an interface between the network layer and the medium access control (MAC) sublayer of the data link layer.

What is the main function of a data link content monitor?

What is the main purpose of a data link content monitor? to determine the type of switching used in a data link.

What is the purpose and function of the data link layer in preparing communication for transmission on specific media?

The Data Link layer is responsible for communications between end-device network interface cards. It allows upper layer protocols to access the physical layer media and encapsulates Layer 3 packets (IPv4 and IPv6) into Layer 2 Frames. It also performs error detection and rejects corrupts frames.

What do network hosts use data link layer addresses for?

The data link layer addresses are added to the IP header. … The destination IP address is used for end-to-end delivery of data to a remote network. The destination MAC address is used for delivery on a local network. The destination port number identifies the application that should process the data at the destination.

What is MAC address explain?

MAC address is the physical address, which uniquely identifies each device on a given network. … It stands for Media Access Control, and also known as Physical address, hardware address, or BIA (Burned In Address). It is globally unique; it means two devices cannot have the same MAC address.

What is the purpose of MAC address?

MAC address is a unique number which is used to track a device in a network. MAC address provides a secure way to find senders or receivers in the network and helps prevent unwanted network access. Mac address is also used in Wi-Fi networks at the airport for a specific device in order to identify it.

What is MAC address explain with example?

A MAC address is a hardware identification number that uniquely identifies each device on a network. … For this reason, MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e.

Which address is used in transport layer?

At the end systems the Transport layer protocols use the IP address for transport layer multiplexing or demultiplexing. When a segment arrives at the host the transport layer depending on the type of protocol used(TCP or UDP) extracts the data and guides it to the correct socket(Demultiplexing).

What addressing scheme is used at the transport layer?

TCP/IP includes an Internet addressing scheme that allows users and applications to identify a specific network or host with which to communicate. An Internet address works like a postal address, allowing data to be routed to the chosen destination.

What is meant by network address?

A network address is an identifier for a node or host on a telecommunications network. … Network addresses can be flat addresses which contain no information about the node’s location in the network (such as a MAC address), or may contain structure or hierarchical information for the routing (such as an IP address).

Which destination address is used in an ARP?

The purpose of an ARP request is to find the MAC address of the destination host on an Ethernet LAN. The ARP process sends a Layer 2 broadcast to all devices on the Ethernet LAN. The frame contains the IP address of the destination and the broadcast MAC address, FFFF.FFFF.

What is the IP address of the switch virtual?

If there are no DHCP servers available, the switch will use its factory default IP address which is

What IP address uses 128 bits?

IPv6 IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total.
