Which of the following is not a data link layer technology? HTTP is not a data link layer technology. HTTP (Hypertext transfer protocol) that works on application layer of OSI model that is sent over TCP.
Which are data link layer technology?
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.Examples of data link protocols are Ethernet, Point-to-Point Protocol (PPP), HDLC and ADCCP.

What is Bluetooth technology?
Bluetooth is a wireless communication technology that can be used for close-range data transmission from one digital device to another. Bluetooth is essentially a one-to-one wireless connection that uses 2.4 GHz-band radio waves.When connecting Bluetooth devices for the first time, registration is required.
What is a Level 3 network?
Layer 3 is the network layer and its protocol is the Internet Protocol or IP.Traditionally, the network device most associated with Layer 3 has been the router, which allows you to connect devices in different IP networks.
Which of the following is not the layer of TCP IP protocol?
These 7 Layers of OSI are the application layer, the presentation layer, the session layer, the transport layer, the network layer, the data-link layer, and the physical layer. The presentation layer is absent in the TCP/IP model while it is present in the OSI model.
What are the five duties of data link layer?
