Answer:
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications[1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual systems, that enable users to access, store, transmit, and manipulate information.
The answer is a Mesh topology. This method connects every device to each other device in the network. A wired full-mesh topology is not as common as it is impractical and highly expensive. A partial mesh topology offers redundancy if one of the connections goes down and usually uses a connecting medium such as a router to eliminate cables and expensive PCI NIC's.
Answer:

Explanation:
The computation of the velocity by using the following formula is
As we know that

where,
Displacement is 10 meters
Total time taken is 30 seconds
Now placing these values to the above formula
So, the velocity of Dash is


We simply applied the above formula so that we can get the velocity and the same is to be considered
