Which of these is not a phase of IT development?
-
Mechanical phase
-
Control phase
-
Electronic phase
-
Pre-mechanical phase
Correct Answer
A. Control phaseExplanation
The control phase is not a phase of IT development because it does not involve the actual development or creation of IT systems or software. The control phase typically refers to the phase in which the developed IT systems are monitored, managed, and controlled to ensure their proper functioning and performance. It involves activities such as monitoring system performance, troubleshooting issues, implementing security measures, and making necessary adjustments or improvements to the systems. However, the actual development of IT systems occurs in phases such as the mechanical phase, electronic phase, and pre-mechanical phase.Rate this question:

What was the first random access digital data storage device?
-
Williams tube
-
Cathode ray tube
-
Dayline memory
-
Control tube
Correct Answer
A. Williams tubeExplanation
The Williams tube was the first random access digital data storage device. It was invented in 1946 by Freddie Williams and Tom Kilburn at the University of Manchester. The Williams tube used a cathode ray tube to store and retrieve digital information. It worked by using a beam of electrons to write and read data on a screen coated with a thin layer of phosphor. This allowed for fast random access to stored data, making it a significant advancement in computer memory technology.Rate this question:

When was the first relational database management system made available?
-
1989
-
1987
-
1097
