What PDU format is bits?
A packet is the PDU at the network layer.
A segment is the PDU at the transport layer.
A file is a data structure that may be used at the application layer..
Which two protocols operate at the top layer of the TCP IP protocol suite choose two?
Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.)DNS.Ethernet.IP.POP.TCP.UDP. Explanation: The application layer is the top layer of the TCP/IP protocol stack. Application layer protocols include HTTP, DNS, HTML, TFTP, POP, IMAP, FTP, and SMTP.
What is a characteristic of multicast messages?
They are sent to a select group of hosts. They are sent to all hosts on a network. Explanation:Multicast is a one-to-many type of communication. … Multicast messages are addressed to a specific multicast group.
What is the purpose of MAC sublayer?
The MAC sublayer emulates a full-duplex logical communication channel in a multipoint network. This channel may provide unicast, multicast, or broadcast communication service. The MAC sublayer uses MAC protocols to prevent collisions.
Which two functions are performed at the LLC sublayer?
Which two functions are performed at the LLC sublayer of the OSI data link layer? (Choose two.)Enables IPv4 and IPv6 to utilize the same network interface and media.Adds Layer 2 control information to network protocol data.Integrates various physical technologies.Implements a trailer to detect transmission errors.More items…•
What are network layers?
The “network layer” is the part of the Internet communications process where these connections occur, by sending packets of data back and forth between different networks. In the 7-layer OSI model (see below), the network layer is layer 3.
What is LLC protocol Wireshark?
Logical Link Control (LLC, IEEE 802.2) protocols as its transport protocol: Ethernet: LLC can be used for packets on Ethernet networks, although many protocols don’t use it when running atop Ethernet. IEEE_802. 11: LLC is used for data packets on IEEE_802. … FDDI: LLC is used for data packets on FDDI networks.
What are the functions of MAC layer?
The medium access control (MAC) is a sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It is responsible for flow control and multiplexing for transmission medium. It controls the transmission of data packets via remotely shared channels.
What type of communication will send a message to all devices on a local area network?
What type of communication will send a message to all devices on a local area network? Explanation: Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication.
What are the two features of ARP?
What are two features of ARP? (Choose two.)When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.An ARP request is sent to all devices on the Ethernet LAN and contains the IP address of the destination host and its multicast MAC address.More items…•
What type of network traffic requires QoS?
Explanation:Video conferencing utilizes real-time audio and video communications. Both of these are time-sensitive and bandwidth-intensive forms of communication that require quality of service to be active on the network. QoS will ensure an uninterrupted user experience.
What is the role of LLC sublayer?
Logical Link Control (LLC) sublayer provides the logic for the data link. Thus, it controls the synchronization, flow control, and error checking functions of the data link layer. Media Access Control (MAC) sublayer provides control for accessing the transmission medium.
What is the difference between LLC and MAC?
The MAC layer is used for defining the working or functionality of which is unique for a particular network technology like Ethernet. The LLC (logical link control) layer is functionality which can be used in all LANs irrespective of the underlying physical technology which is used to implement the LAN.
What are three characteristics of multicast transmission choose three?
What are three characteristics of multicast transmission? (Choose three.)The source address of a multicast transmission is in the range of 224.0. … A single packet can be sent to a group of hosts.Multicast transmission can be used by routers to exchange routing information.The range of 224.0.More items…
How do I check my Mac?
Windows 10, 8, 7, Vista:Click Windows Start or press the Windows key.In the search box, type cmd.Press the Enter key. A command window displays.Type ipconfig /all.Press Enter. A physical address displays for each adapter. The physical address is your device’s MAC address.
What are the two characteristics of IP?
What are two characteristics of IP? (Choose two.)does not require a dedicated end-to-end connection.operates independently of the network media.retransmits packets if errors occur.re-assembles out of order packets into the correct order at the receiver end.guarantees delivery of packets. Explanation:The Internet Protocol (IP) is a connectionless, best effort protocol.
What are the two protocols?
Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol.
What is a characteristic of the LLC?
Characteristics of limited liability company include separate legal existence, limited liability, flexibility in taxation, and simplicity in operation.
