Top best answers to the question «Layer 2 data link switches are software based»
- A layer 2 switch is a type of network switch or device that works on the data link layer ( OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN).

Layer 2 switches, operating at the Data Link layer, can be programmed to respond automatically to a wide range of circuit conditions. By monitoring control and data events, these switches automatically reroute circuits or switch to backup equipment, as the need requires.
Through Layer-2 switches, we can send data frame from the source to the destination that is situated in the same VLAN easily without being physically connected or being at the same location. Thus the servers of a software company can be put centrally at one location and the clients dispersed at the other locations can access the data easily without latency and thereby save the server cost and time.
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 adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment. 
Layer 2 is Data Link Layer (DLL) as per OSI Model. As we know function of each layer is to provide services to above layer, so DLL provide various services to Layer 3: Network Layer. Various services which DLL provides are: Framing network layer data packets. Flow Control.
Switches can also have ACLs based on MAC and IP addresses. The difference between layer 2 and layer 3 switches is that layer 3 switch can support ACLs based on both MAC and IP addresses whereas...
Layer-2 Switches: Layer-2 switches are the devices which forward the data to the next layer on the basis of the physical address (MAC address) of the machine. Firstly it gathers the MAC address of the device on the port on which the frame is to be received and later learns the destination of the MAC address from the address table and forwards the frame to the destination of the next layer.
What is the difference between a bridge and layer-2 switch? (Choose all that apply.) a. Switches are software based. b. Bridges are hardware based. c. Switches are hardware based d. Bridges are software based
