Questions and Answers

1.

Which of these is the most appropriate computer component to store data In electronic form for future use?
- A.
  
  Hard drive
- B.
  
  RAM
- C.
  
  Laser printer
- D.
  
  Mouse
Correct Answer
A. Hard drive

Explanation
A hard drive is the most appropriate computer component to store data in electronic form for future use because it is designed specifically for long-term data storage. It has a large storage capacity and can retain data even when the computer is turned off. In contrast, RAM is volatile memory that is used for temporary data storage while the computer is running. Laser printers and mice are peripheral devices that do not store data.

One advantage of using a CD for data storage Is:
- A.
  
  It is a primary storage.
- B.
  
  It is human-readable.
- C.
  
  It can be reused.
- D.
  
  It Is read-only.
Correct Answer
B. It is human-readable.

Explanation
The correct answer is "It is human-readable." This means that the data stored on a CD can be easily understood and accessed by humans. Unlike other forms of data storage, such as magnetic tapes or hard drives, CDs do not require any special equipment or software to read the data. This makes CDs a convenient and versatile option for storing and sharing information.

Main memory is also referred to as:
- A.
  
  ALU
- B.
  
  CU
- C.
  
  CPU
- D.
  
  RAM
Correct Answer
D. RAM

Explanation
Main memory is also referred to as RAM (Random Access Memory). It is the term commonly used to describe the computer's main volatile memory, where data and programs are temporarily stored while the computer is in operation.

Which of the following Is a device Interface used in a computer system?
- A.
  
  SSD
- B.
  
  Hard disk drive
- C.
  
  USS
- D.
  
  CD-ROM
Correct Answer
A. SSD

Explanation
SSD stands for Solid State Drive, which is a device interface used in a computer system. It is a type of storage device that uses flash memory to store data. Unlike traditional hard disk drives (HDD), SSDs have no moving parts, making them faster, more reliable, and more energy-efficient. They connect to the computer system through various interfaces such as SATA, PCIe, or NVMe. SSDs have become increasingly popular due to their faster read and write speeds, which significantly improve overall system performance.

Which of the following statements is true about ROM?
- A.
  
  New data can be written to ROM.
- B.
  
  H is non-volatile.
- C.
  
  The contents are lost when the computer Is turned off.
- D.
  
  It is volatile.
Correct Answer
B. H is non-volatile.

Explanation
ROM stands for Read-Only Memory, which means that the data stored in ROM cannot be modified or written to once it is programmed during manufacturing. It is non-volatile, which means that the data remains intact even when the computer is turned off. This is in contrast to volatile memory, such as RAM, where data is lost when the power is turned off. Therefore, the statement "H is non-volatile" is true for ROM.

If a file allows direct access. what does that mean?
- A.
  
  The computer has read-only access to the file.
- B.
  
  The computer can Immediately read any record in the file.
- C.
  
  The file is printed out so you can read it directly.
- D.
  
  You do not need a password to access the file.
Correct Answer
A. The computer has read-only access to the file.

Explanation
If a file allows direct access, it means that the computer has read-only access to the file. This means that the computer can retrieve information from the file, but cannot make any changes or modifications to it. Direct access allows the computer to immediately read any record in the file, without the need for sequential searching or scanning through the entire file. It does not mean that the file is printed out or that no password is required to access it.

Which of these features is essential for a process control application?
- A.
  
  Human-readable documents
- B.
  
  Wi-Fi connectivity
- C.
  
  Sensor input
- D.
  
  Graphical interface
Correct Answer
C. Sensor input

Explanation
A process control application requires sensor input in order to monitor and control various parameters of a process. This input allows the application to gather real-time data and make necessary adjustments to ensure optimal performance. Human-readable documents may be helpful for documentation purposes, but they are not essential for the application itself. Wi-Fi connectivity and a graphical interface may enhance the functionality and user experience, but they are not essential features for the basic operation of a process control application.

Typing two letters in the wrong order ls an example of:
- A.
  
  Transposition errors
- B.
  
  Data verification
- C.
  
  Data type error
- D.
  
  System error
Correct Answer
A. Transposition errors

Explanation
Transposition errors refer to the act of typing two letters in the wrong order. This can occur when a person accidentally switches the positions of two adjacent letters while typing. It is a common mistake that can happen due to human error or typographical errors. Transposition errors can lead to incorrect spelling or inaccurate data entry, and they are often caught during data verification processes.

Which of the following is an appropriate application for a super computer?
- A.
  
  Word processing
- B.
  
  Weather forecasting
- C.
  
  3D gaming d Payroll Processing
- D.
  
  Payroll processing
Correct Answer
B. Weather forecasting

Explanation
Weather forecasting requires complex mathematical calculations and simulations that involve large amounts of data. Supercomputers are specifically designed to handle these types of tasks, as they have the capability to process and analyze massive amounts of data at incredibly high speeds. This makes them ideal for applications such as weather forecasting, where accurate and timely predictions are crucial. Word processing, 3D gaming, and payroll processing can be performed on regular computers or even smartphones, as they do not require the same level of computational power as weather forecasting.

A graphical user interface usually consists of:
- A.
  
  Pascal commands
- B.
  
  Video clips
- C.
  
  DOS commands
- D.
  
  Icons
Correct Answer
D. Icons

Explanation
A graphical user interface usually consists of icons. Icons are small graphical representations that are used to represent files, folders, applications, and various functions within a graphical user interface. They provide a visual representation of different elements and allow users to interact with them by clicking or tapping on them. Icons are an essential component of graphical user interfaces as they make it easier for users to navigate and interact with the system.
