Answer:
Transport Layer
Explanation:
The transport layer which is responsible for end-to-end communication over a network. Transport Layer breaks the data, allocated by Application layer in smaller units called segments. It is used to number every byte in the segment. It is also responsible for error correction and provides reliability to the user. It allows the host to send and receive error corrected data, messages or packets over a network and ensures that data should be received in the same sequence in which it was sent. It also enables multiplexing and flow control.
(9m - 6)7
(9m × 7) - (6 × 7)
63m - 42
Some options are add to dictionary, ignore once, ignore all, autocorrect, change, and change all.
Answer: See explanation
Explanation:
Digital literacy is when an individual can compose, find, and evaluate, a clear and composed information on digital platforms.
It involves possessing the skills that one need to live, and learn, through the use of digital platforms such as social media, mobile
Example of digits literacy is the use of search engines, understanding how web browser can be used or sending of emails. etc
Answer:
Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
- Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops.
- These loops are called physical loops.
- When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
- This affects the performance of the network as the result of broadcast packets flooding.
- STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
- Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
- Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
- This information helps STP to eliminate the redundant paths.
- So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.
