Answer:RISC(reduced instruction set computer) is the computer used for low level operation by simple command splited into numerous instructions in single clock only and CISC(Complex instruction set computer) is the computer that performs the operation in single instruction.

RISC architecture has hardwired control unit,data cache unit,data path ,instruction cache and main memory as components .CISC architecture persist of control unit,micro program control memory, cache, instruction and data path and main memory.

The differences between RISC and CISC are as follows:-

The instruction in RISC are less and and low complexes while CISC has several number of complex instruction.
The calculation done by RISC are precise and quick whereas CISC has slightly slow calculation processing.
The execution of RISC is faster as compared to CISC.
RISC uses hardware component for implementation of instruction because it does not persist its own memory and CISC implements instructions using its own memory unit .

Answer:

Command remembering issues.

Explanation:

The biggest challenge my company will face when working on Linux is remembering issues of the commands.

Damm [24]

Answer:

<u>a. The scientists must be careful of how many variables they include in their simulation so they do not cause further harm to the frogs.</u>

Explanation:

It is not statistically accurate to assume that the number of variables included in the simulation would cause further harm to the frogs because we need to <em>remember </em>that a simulation is simply a computerized imitation of a real situation, which is usually not totally alike with a real process.

So in no way from a statistical standpoint, does the scientists' decision on the number of variables causes direct harm to the frogs.
