Which layer of the OSI model is responsible for error detection and correction
Correct answer: C. Data Link Layer
- A. Application Layer
- B. Presentation Layer
- C. Data Link Layer
- D. Physical Layer
Explanation
The Open Systems Interconnection (OSI) model is a conceptual framework for understanding network communication. It divides network communication into seven layers, each with specific functions.● Data Link Layer: This layer is responsible for error detection and correction in data transmission. It ensures that data packets are delivered accurately between network nodes. Common data link layer protocols include Ethernet and Wi-Fi.● Application Layer: The application layer is the top layer of the OSI model. It provides network services to applications running on user devices. Examples of application layer protocols include HTTP (web browsing), FTP (file transfer), and SMTP (email).● Presentation Layer: The presentation layer formats data for presentation to the application layer. It can handle data encryption, decryption, and compression.Physical Layer: The physical layer transmits and receives raw data bits across the network medium (cables, wires, etc.). It defines the electrical or optical specifications for network connections

About Networking and Internet
Networking covers LAN, MAN, WAN and wireless networks, network topologies, transmission media, devices such as switches, routers and modems, and the OSI and TCP/IP models. Internet concepts include IP addresses, DNS, URLs, web browsers, email, protocols such as HTTP, HTTPS, FTP and SMTP, and basic network security.
