involves connecting geographically remote computers into a single network and combining the computational power of all computers on the network. It takes advantage of the the fact that most computers use their central processing units on average only 25 percent of the time, leaving 75 percent of their capacity available for other tasks.

Explanation:

Grid computing  involves connecting geographically remote computers into a single network and combining the computational power of all computers on the network. It takes advantage of the the fact that most computers use their central processing units on average only 25 percent of the time, leaving 75 percent of their capacity available for other tasks.

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.

it would be a. excessive network collisions or d. slow connectivity between devices those would be my answer.
