The ALU of a central processing unit does the essential maths work for the computer. What does the control unit do?
Correct Answer
C. Monitors the flow of information
Explanation
The control unit of a central processing unit (CPU) is responsible for coordinating and controlling the flow of information between various components of the computer system. It manages the execution of instructions, ensuring that they are carried out in the correct sequence and at the appropriate time. The control unit also monitors the flow of data and instructions between the memory, input/output devices, and the arithmetic logic unit (ALU). This ensures that the computer operates smoothly and efficiently, allowing for the proper execution of tasks and the communication of results.

A storage device which is used to store data & information external to the main storage is known as
Correct Answer
B. Backing storage
Explanation
Backing storage refers to a storage device that is used to store data and information external to the main storage. It is commonly used for long-term storage and includes devices such as hard drives, solid-state drives, and optical discs. Backing storage allows for the retention of data even when the power is turned off, making it a reliable and convenient option for storing large amounts of information.

What does that acronym VGA stand for?
Correct Answer
C. Video GrapHics Array
Explanation
VGA stands for Video Graphics Array. It is a display standard that was introduced by IBM in 1987. VGA provides a resolution of 640x480 pixels with 16 colors or 320x200 pixels with 256 colors. It became the de facto standard for computer displays for many years and is still commonly used today, especially in legacy systems.
4.
Which part of the diskette should never be touched?
Correct Answer
C. Oval slot
Explanation
The oval slot of a diskette should never be touched because it is where the read/write head of the disk drive makes contact with the disk. Touching the oval slot can leave fingerprints or debris on the disk, which can interfere with the reading and writing of data. This can lead to data loss or corruption. It is important to handle diskettes carefully and only touch the edges or the center hole when inserting or removing them from the disk drive.
5.
The storage locations in the internal storage of a CPU are called
Correct Answer
B. Addresses
Explanation
The storage locations in the internal storage of a CPU are referred to as addresses. Addresses are used to locate and access specific data stored in the internal memory of the CPU. They serve as unique identifiers for each storage location, allowing the CPU to read or write data to the desired location. By using addresses, the CPU can efficiently retrieve and manipulate data in its internal storage, enabling the execution of various instructions and tasks.

One of the main features that distinguish microprocessors from microcomputers is
Correct Answer
C. Microprocessor does not contain I/O devices
Explanation
Microprocessors and microcomputers are both types of computer systems, but one of the main features that distinguishes them is the presence of I/O (input/output) devices. While microcomputers typically have built-in I/O devices like keyboards, monitors, and printers, microprocessors do not. Microprocessors are the central processing units (CPUs) of computer systems and are responsible for executing instructions and performing calculations. They rely on external devices for input and output functions. Therefore, the correct answer is that microprocessors do not contain I/O devices.
7.
Which of the following is not true of future computers?
Correct Answer
E. All of the above are true
Explanation
The given answer states that all of the options mentioned in the question are true for future computers. This means that future computers will indeed have increased use of CAD/CAM techniques, faster turnaround time, developments in artificial intelligence systems, and development of products more suitable for human use.
8.
The EAM device that does not use a control panel is the:
Correct Answer
D. Sorter
Explanation
The correct answer is sorter. A sorter is an EAM (Electro-Acoustic-Mechanical) device used to sort punched cards based on predetermined criteria. Unlike other EAM devices such as collators, reproducers, and interpreters, a sorter does not require a control panel for operation. It simply sorts the punched cards into different output bins based on the designated sorting criteria.
9.
A floppy disk contains:
Correct Answer
C. Both circular tracks and sector
Explanation
A floppy disk contains both circular tracks and sectors. Circular tracks are concentric rings on the surface of the disk, while sectors are divisions within each track. The combination of circular tracks and sectors allows for the storage and retrieval of data on the floppy disk.
10.
A typical modern computer uses:
Correct Answer
A. LSI chips
Explanation
A typical modern computer uses LSI chips, which stands for Large Scale Integration chips. LSI chips are integrated circuits that contain a large number of transistors and other electronic components on a single chip. These chips are commonly used in modern computers due to their compact size, low power consumption, and high performance capabilities. LSI chips allow computers to process and store large amounts of data efficiently, making them an essential component in modern computer systems.
