Which layer arranges the transmission of a data frames bits when they are dispatched across the network?
The Data Link layer is responsible for arranging the transmission of data frames' bits when they are dispatched across the network. It ensures reliable transfer of data frames between directly connected nodes by managing error detection and correction, as well as framing and addressing. This layer operates above the Physical layer, which handles the actual transmission of raw bit streams over the physical medium.
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
The data link layer handles transmission errors by requesting damaged frames to be?
Damaged frames are discarded. Retransmission - if needed - is handled by higher-layer protocols, like TCP.
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames 2.dividing the application data into segments?
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames? Data link layer Which of the OSI layers handle the following: 2.dividing the application data into segments? Transport layer the PDU (Packet Data unit) for layers is as the following - Application, Presentation, and Session layers ==> uses Data - Transport layer ==> uses Segment - Network layer ==> uses Packets - Data link layer ==> uses Frames - Physical layer ==> uses Bits. ....
What is the process of dividing a data stream into smaller pieces before transmission?
The process of dividing a data stream into smaller pieces before transmission is known as segmentation. This involves breaking the data into manageable packets or segments, each typically containing a portion of the data along with headers that include metadata such as sequence numbers and checksums for error detection. This segmentation allows for more efficient transmission over networks, as smaller packets can be routed independently and can help in managing network congestion. Once received, the segments are reassembled into the original data stream at the destination.
What is bit stuffing removal?
Bit stuffing removal is a process used in data communication to eliminate extra bits that were added to ensure synchronization and prevent misinterpretation of data frames. During transmission, a '0' is inserted after a sequence of five consecutive '1's to avoid confusion with frame delimiters. At the receiving end, the bit-stuffing removal process identifies these inserted bits and removes them, restoring the original data stream for accurate interpretation. This technique helps maintain data integrity while ensuring efficient transmission.
What are characteristics of the Ethernet data transmission standard?
Data transmissions is via frames, each having a single MAC address. The CSMA/CD access method is used to detect collisions.

Discuss the meaning what terms control frame management frame and data frame?
Management frames are those involved in association and reassociation, such as the probe and beacon frames. Control frames are those related to medium access and data delivery, such as the ACK and RTS/CTS frames. Data frames are those that carry the data sent between stations.
What happens to runt frames?
Runt frames are Ethernet packets that are smaller than the minimum allowed size of 64 bytes. When a network device encounters a runt frame, it typically discards it because it is considered a transmission error, which can occur due to collisions or faulty network equipment. Runt frames do not get processed further in the network, helping to maintain the integrity and efficiency of data transmission.
What are the three types of HDLC frames?
The three types of HDLC (High-Level Data Link Control) frames are: Information Frames (I-Frames): Used for carrying user data and control information, facilitating data transfer between devices. Supervisory Frames (S-Frames): Employed for control and management purposes, such as acknowledging received frames and controlling flow. Unnumbered Frames (U-Frames): Utilized for link management and control functions, allowing for operations like establishing or terminating connections.
What is the definition for Asynchronous communication?
In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream
