$22.$ Grid computing is a type of computing in which:

a$.$ special software is installed on several computers enabling them to work together on a common problem.

b$.$ computers are designed with many microprocessors that work together, simultaneously, to solve problems.

c$.$ quantum properties, such as superposition and entanglement, are used to represent data and perform operations on these data.

d$.$ microprocessors with two or more $($typically lower power$)$ calculating processor cores are fabricated on the same piece of silicon to solve multiple problems.

e$.$ computer software seeks to reproduce or mimic human thought, decision making, or brain functions.
