Computer networks refer to inter-connected systems of computers and other devices that facilitate communication and the sharing of resources. They enable the transfer of data and information between multiple devices, allowing users to access resources, such as files, printers, and internet connectivity. Computer networks can be local area networks (LANs), connecting devices within a limited area, or wide area networks (WANs), connecting devices across larger geographical distances. They rely on protocols and networking technologies to establish connections and ensure efficient and secure data transmission. Computer networks play a vital role in various domains, including businesses, education, research, and personal communication, enabling collaboration, information sharing, and access to remote resources. Check your knowledge of Computer Networks about operating systems by solving the given Computer Networks MCQs.

Concept:
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer.
The data link layer is responsible for the node-to-node delivery of the message. The main function of this layer is to make sure data transfer is error-free from one node to another, over the physical layer.
Hence the correct answer is Data Link Layer.
Additional Information Transport Layer:
It is Layer 4 of the OSI Model. Transport Layer provides transparent transfer of data between end-users, providing reliable data transfer services to the upper layers. The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control.
Physical Layer:
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer; The layer most closely associated with the physical connection between devices. This layer may be implemented by a PHY chip.
Network Layer:
In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers.
