Computer fundamental MCQ Questions and answers- Technical Aptitude

Execution in computer and software engineering is the process by which a computer or virtual machine reads and acts on the instructions of a computer program. Execution involves repeatedly following a 'fetch – decode – execute' cycle for each instruction.

Integrated Circuits, also called ICs or informally, "microchips" or just "chips", are miniature electronic circuits built onto a single (very small) piece of silicon embedded in a package that allows it to be connected to a circuit.

Option A: addition processor:
This isn't a standard term. While adding more cores to a CPU helps, it's usually done through a motherboard upgrade, not an "addition processor."

Option B: expansion cards:
This is the correct answer.
Expansion cards are like add-ons you plug into your computer's motherboard.
They can add new functionalities or improve existing ones.
For example, you can add a graphics card (GPU) to enhance video processing,
a sound card to improve audio, or a network card for faster internet.
These improvements directly enhance the microcomputer's processing capabilities.

Option C: secondary memory:
Secondary memory (like a hard drive or SSD) is for storing data.
It doesn't directly make the computer process information faster.
It only allows you to store more data.

Option D: buffer memory:
Buffer memory is a small, fast memory used to temporarily store data during processing.
While it helps with data flow, it doesn't significantly enhance the overall processing capability of the microcomputer.
It's more of a fine-tuning mechanism.

Option E: None of the above:
Since option B is correct, this option is incorrect.

Therefore, the best answer is B: expansion cards because they provide a direct way to enhance a microcomputer's processing capabilities by adding dedicated hardware for specific tasks.

In the Chandigarh silicon chips manufactured in India. A silicon chip is an integrated circuit made primarily of silicon. Silicon is one of the most common substances used to develop computer chips.

A computer programmer, sometimes called a software developer, a programmer or more recently a coder (especially in more informal contexts), is a person who creates computer software. Logical thinking is an important trait in a programmer. It is also referred to as analytical reasoning, abstract thinking or critical thinking. People that can think logically are able to analyse problems and devise solutions.

Buckminster Fuller "The three most important inventions of this century are the nuclear bomb, the high yield hybrid speed, and the computer".

A menu-driven operating system is one which allows you to pick up from the menu of choices it displays on the screen. If you describe something or someone as an icon, you mean that they are important as a symbol of something. She has been described as 'an icon of style'.

Difference Engine, an early calculating machine, verging on being the first computer, designed and partially built during the 1820s and '30s by Charles Babbage. Charles Babbage began to construct a small difference engine in c. 1819 and had completed it by 1822 (Difference Engine 0).

The IBM Automatic Sequence Controlled Calculator, called Mark I by Harvard University’s staff, was a general purpose electromechanical computer that was used in the war effort during the last part of World War II. One of the first programs to run on the Mark I was initiated on 29 March 1944 by John von Neumann.
