(B) 1, 2, 3 and 4
(C) 4, 2, 3 and 1
(D) 4, 3, 2 and 1​

Answer 1

Answer:

The answer is a option A

Answer 2

The correct order of the development is - option B) 1,2,3 and 4

Explanation:

The correct order of the development is-

1.Numerical control

2. Computer numeric  control

3. Direct numerical control

4. Distributed numerical control

The most punctual NC machines performed  restricted capacities and developments controlled by punched tape or punch cards . As the innovation advanced, the machines were prepared  with progressively capable chip ( computers) with the expansion of these computers , NC machines gotten to be CNC machines .  After the coordinate numeric control DNC too called conveyed numerical were advanced with progressive off innovation of working remotely.

1. Numerical control- Numerical control ( moreover computer numerical control , and commonly called  CNC) is the robotized control of machines devices.

2. Computer numeric control- Computer Numerical control  (CNC)  may be a procedure for robetizing control of machine devices though the utilize of computer program embedded in a microcomputer joined to the device.

3.Direct Numerical control - Direct numerical control, moreover known as disseminated numerical control, may be a common fabricating term for organizing  CNC machine instrimunets.

4. Distributed Numerical control- The cordinate numerical or distributive numerical control(DNC) are control advanced coordinate or computerized control innovation of dispresed.
