Review Materi Datalink Layer

Full Duplex adalah jenis komunikasi data point to point di mana kedua peralatan dapat mengirim dan menerima pada media yang sama secara bersamaan. Hal ini berarti bahwa komunikasi dapat terjadi dalam dua arah secara simultan, di mana kedua peralatan dapat mengirim dan menerima data secara bersamaan tanpa harus menunggu giliran. Dalam mode Full Duplex, tidak ada pembatasan waktu untuk pengiriman data dan tidak ada konflik antara pengiriman dan penerimaan data.

The correct answer is "Lapisan data link bertanggung jawab dalam pertukaran frame antar node menggunakan media fisik jaringan." This statement accurately describes the responsibility of the data link layer, which is to facilitate the exchange of frames between nodes using the physical network media.

The correct answer is Media Access Control (MAC). The MAC sublayer of the data link layer provides addressing mechanisms and restricts data according to the type of media and the type of data link protocol being used. It is responsible for controlling access to the physical network medium and ensures that only one device transmits at a time to avoid collisions. The MAC sublayer also handles the formatting and transmission of data packets.

The control information, including the address information of a frame, is located in the header section.

A network interface card (NIC) is a device that allows an end device to connect to a network. It handles the framing and media access control, allowing the device to communicate with other devices on the network. The NIC acts as an interface between the device and the network, enabling data transmission and reception.

The given options represent different types of network topologies. Point-to-point and Multi-Access are common logical and physical topologies used in networking. Ring topology is also a common network topology where each device is connected to two other devices forming a circular chain. However, SLIP (Serial Line Internet Protocol) is not a type of network topology but rather a protocol used for communication over serial lines. Therefore, SLIP is the correct answer as it does not represent a network topology.

The correct answer is Frame. The PDU (Protocol Data Unit) at the datalink layer is known as a frame. A frame is a complete unit of data that includes both the data being transmitted and the necessary control information such as source and destination addresses, error detection, and flow control. Frames are used to encapsulate packets and are responsible for reliable transmission of data over the network.

The correct answer is Datalink. The process of framing data packets before transmitting them over the network media occurs at the Datalink layer. This layer is responsible for the reliable transmission of data between two directly connected nodes. It ensures that the data is properly formatted into frames with appropriate headers and trailers for error detection and correction. The Datalink layer also handles the physical addressing of devices on the network.

The correct answer states that the process of framing divides the data stream into several groups by inserting control information in the header and trailer as values in different fields. This means that the data is divided into smaller segments or frames, with each frame containing control information in the header and trailer. This helps in organizing and managing the data transmission process effectively.

The given options are all components of the data link layer except for "Packet." The data link layer is responsible for the reliable transfer of data between two nodes on a network. It includes the header, data, and trailer components. The packet, on the other hand, is a unit of data that is transmitted over a network. It is typically composed of the header, data, and trailer, but it is not a component of the data link layer itself. Therefore, "Packet" is the correct answer.

The given question asks for the field that is not present in the header frame. The options provided are Frame start, Addressing, Error Detection, and Quality Control. The correct answer is Error Detection. This means that the error detection field is not included in the header frame. The header frame typically contains information such as the frame start, addressing, and quality control. Error detection is a separate process that is performed on the data transmitted, but it is not included as a field in the header frame.

The correct answer is Media Access Control. The explanation is that layer 2 of the protocol stack is responsible for encapsulating packets into frames, and the technique used for framing the packets depends on the data transmission medium. The Media Access Control (MAC) is a sublayer of layer 2 that controls access to the transmission medium and ensures that multiple devices can share the medium efficiently.

The correct answer is "Institute of Electrical and Electronics Engineers". IEEE is an organization that publishes standards for the datalink layer in engineering.

Multi-Access is the correct answer because it refers to a topology that allows multiple nodes to communicate and share the same media. In this topology, data originating from one node can be placed on the media at any time, and other nodes will be able to see the frame. However, only the intended destination node will respond to the frame.

The trailer is the part of the data link frame that contains control information added at the end of the Protocol Data Unit (PDU). It is used for error detection and correction purposes. The trailer typically includes a frame check sequence (FCS) or a cyclic redundancy check (CRC) that allows the receiving device to verify the integrity of the data. By checking the FCS or CRC, the receiver can determine if any errors occurred during transmission and request retransmission if necessary.

The correct answer is "Logical Link Control (LLC)". The Data Link layer consists of two sublayers, the upper sublayer and the lower sublayer. The upper sublayer is responsible for managing the logical link control, which includes error checking, flow control, and framing of data packets. The LLC sublayer ensures reliable and error-free transmission of data between the network layer and the physical layer.

CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance. It is a method used to detect whether the wireless medium is currently transmitting a signal or not, in order to prevent chaos in the use of the medium. This method helps to avoid collisions between data packets by implementing a virtual carrier sensing mechanism. It requires stations to first listen to the medium and wait for a clear channel before transmitting their data. This helps to ensure that only one station transmits at a time, reducing the chances of collisions and improving the overall efficiency of the wireless network.
