Why binary language is often termed as machine language? Why is machine language required?

Q19. Why binary language is often termed as machine language? Why is machine language required?

Ans. A computer (the machine) operates on electricity. Thus, it can understand only electricity signals that are just two – ON and OFF or high voltage and low voltage. Thus it needs a language that uses just two unique symbols to represent these two states of electricity. Therefore, a computer works on the machine language. The binary language is often termed as machine language as it fulfills the condition of using two unique symbols to represent two states of electricity.

How is a compiler different from interpreter?

Q14. How is a compiler different from interpreter?

Ans. A compiler converts the source code (program in high level language) into object coe (Machine language code) in one go and reports all the errors along with their line numbers.

An interpreter converts source code into object cod line by line and executes it there and then. It does not shift to the next line if the line is erroneous.

Correlation Among Digital, Analog, Special-Purpose, And General-Purpose Computers.

Q13. What is the correlation among digital, analog, special-purpose, and general-purpose computers?

Ans. Most digital computers are general-purpose whereas most analog computers are special purpose.

Distinguish Between A General-Purpose And A Special-Purpose Computer.

Q11. Briefly distinguish between a general-purpose and a special-purpose computer.

Ans. A general-purpose computer is designed to solve a variety of problems whereas a special-purpose computer is designed to solve a specific problem. The automobile cruise control computer is a special-purpose computer and typical laptop computer is a general-purpose computer.
