Smallest unit of information computer can work with is __________.

Correct Answer
bit

Explanation
A bit is the smallest unit of information that a computer can work with. It is a binary digit, representing either a 0 or a 1. Computers process and store data in the form of bits, which are then used to encode and represent more complex information. Bits are the foundation of all digital information and are essential for computer operations and calculations.

A computer used in an ATM has a ___________.
- A.
  
  Graphics tablet
- B.
  
  Mouse
- C.
  
  Touch screen
- D.
  
  Pointing device
Correct Answer
C. Touch screen

Explanation
A computer used in an ATM has a touch screen because it allows users to interact with the machine by touching the screen instead of using a mouse or other pointing device. This enables users to input their PIN numbers, select different options, and navigate through the ATM's interface easily and conveniently. The touch screen technology is commonly used in ATMs as it provides a user-friendly and intuitive way for customers to carry out their banking transactions.

Which one is a non-impact printer
- A.
  
  Laser
- B.
  
  Daisy wheel
- C.
  
  Dot matrix
- D.
  
  Non of the above
Correct Answer
A. Laser

Explanation
A laser printer is a non-impact printer because it does not physically strike the paper to create an image. Instead, it uses a laser beam to transfer toner onto the paper, producing high-quality prints. This method is quieter, faster, and more precise compared to impact printers like daisy wheel or dot matrix printers, which use physical contact to create characters on the paper. Therefore, the correct answer is laser.

Which of these is not a secondary storage?
- A.
  
  Blu-ray disc
- B.
  
  RAM
- C.
  
  Pen drive
- D.
  
  CD
Correct Answer
B. RAM

Explanation
RAM (Random Access Memory) is not considered a secondary storage because it is a form of primary storage. Secondary storage refers to non-volatile storage devices that are used to store data for long-term use, even when the power is turned off. RAM, on the other hand, is volatile memory that is used by the computer to temporarily store data and instructions that are actively being used by the CPU. It is much faster than secondary storage devices but does not retain data when the power is turned off.

Which of these is not a type of ROM?
- A.
  
  PEROM
- B.
  
  PROM
- C.
  
  EPROM
- D.
  
  EEPROM
Correct Answer
A. PEROM

Explanation
PEROM is not a type of ROM. The other options, PROM, EPROM, and EEPROM, are all types of ROM (Read-Only Memory) that have different characteristics and capabilities. PROM stands for Programmable Read-Only Memory, EPROM stands for Erasable Programmable Read-Only Memory, and EEPROM stands for Electrically Erasable Programmable Read-Only Memory. These types of ROM are used in various electronic devices to store permanent data that cannot be easily modified or erased. PEROM is not a commonly known type of ROM and is not used in the same way as the other options.

Rate this question:
7.

Which of these stores the most data/information?
- A.
  
  CD
- B.
  
  DVD
- C.
  
  Hard disk
- D.
  
  Blue-ray disk
Correct Answer
C. Hard disk

Explanation
A hard disk is capable of storing the most data/information compared to the other options listed. While a CD, DVD, and Blu-ray disk have limited storage capacities, typically ranging from a few hundred megabytes to a few gigabytes, a hard disk can store several terabytes of data. Therefore, a hard disk is the most suitable option for storing large amounts of data or information.
