Computer fundamental MCQ Questions and answers- Technical Aptitude

Graphical pictures that represent an object like file, folder etc are known as Icons.

Icons are small graphical representations of programs, files, folders, and other objects on your computer.

Task bar is a bar displayed on the screen that contains buttons for running programs and other controls.

Windows are the rectangular areas of the screen where programs and content are displayed.

Desktop is the main screen area that you see after you turn on your computer and log on to Windows.

Therefore, the correct answer is Option C: Icons.

Option B is not an advantage of magnetic disk storage because:

Magnetic disk storage tends to be more expensive than magnetic tape storage, especially when comparing cost per unit of data storage.

Magnetic tapes are generally used for cost-effective long-term storage and archival purposes, whereas magnetic disks offer faster access times and are used for active storage.

Therefore, stating that disk storage is less expensive is incorrect, making Option B the right choice as it is not an advantage of magnetic disk storage.

In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit.

The most commonly used floppy disks are 3.5 inches and have the capacity of 800 KB to 2.8 MB (with a standard of 1.44 MB). The high-density floppy disk drive was first introduced in 1995.

An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, normally silicon.

This version was released on 25 September 1996. OS/2 is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci.

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.

ENIAC(Electronic Numerical Integrator and Computer) was amongst the earliest electronic general-purpose computers made. It was Turing-complete, digital and able to solve "a large class of numerical problems" through reprogramming.

Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, in the Silicon Valley.

The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first commercially available microprocessor by Intel. The 4004 was the first in a long line of Intel CPUs.

The chip design started in April 1970, when Federico Faggin joined Intel, and it was completed under his leadership in January 1971.
