Answer:
machine language uses binary code and assembly language uses mnemonic codes to write a program.
Explanation:
In a nutshell, machine language uses binary code, which is almost impossible for humans to decipher, whereas assembly language uses mnemonic codes to write a program. Mnemonic codes make it simpler for humans to understand or remember something, and so make the language a bit easier for humans to use than machine code.

Answer:
2125 ns.
Explanation:
First of all Execution Time = Number of Instructions * CPI * Clock Cycle
Number of Instructions = 1000
CPI = 0.5
Clock Cycle = 1/clock rate = 1/4GHz = 0.25 * 10-9 s
So Execution Time = 1000 * 0.5 * 0.25 * 10-9
Execution Time = 125 * 10-9 s
Execution Time = 125 ns
Now 20% of the instructions take 10 ns extra time for remote communication.
1 instruction takes 10ns
so 20% of 1000 = 200 instructions will take 200*10 = 2000ns
So Total Execution Time = 125+2000 = 2125 ns.
