A CD is a type of
- A.
Optical Disk
- B.
Magnetic Disk
- C.
Magnetic Tape
- D.
All of the above
Correct Answer
A. Optical DiskExplanation
A CD is a type of optical disk because it uses laser technology to read and write data. Unlike magnetic disks and tapes, which use magnetic fields to store and retrieve information, optical disks use a series of pits and lands on the surface of the disk to represent data. These pits and lands are read by a laser beam, which detects the changes in reflection and translates them into digital information. Therefore, an optical disk is the correct answer in this case.Rate this question:

_________________ is accessing data in the orderr it was stored
Correct Answer
SERIAL ACCESS
SEQUENTIAL ACCESSExplanation
Serial access and sequential access both refer to the process of accessing data in the order it was stored. In serial access, data is accessed one item at a time, in a linear fashion. This means that to access a specific item, all the previous items must be accessed first. Sequential access, on the other hand, refers to accessing data in a sequential manner, where data is accessed in a predefined order. Both terms essentially describe the same concept of accessing data in a specific order, making them both correct answers to the question.Rate this question:

__________________ is used to access orored data on a disk
Correct Answer
READ WRITE HEADExplanation
The read-write head is used to access or retrieve data that is stored on a disk. It is a component of a disk drive that physically reads and writes data to and from the disk's surface. The read-write head moves across the disk's platter, reading the magnetic patterns that represent the stored data and converting them into readable information. Similarly, it writes data by converting the information into magnetic patterns on the disk's surface. Therefore, the read-write head plays a crucial role in the process of accessing and manipulating data on a disk.Rate this question:

The method used to stored data on a CD is called __________________
Correct Answer
BURNINGExplanation
The method used to store data on a CD is called "burning". This process involves using a laser to create pits on the surface of the CD, which represent the data being stored. These pits are then read by a CD player or drive to retrieve the information. Burning is a widely used method for storing data on CDs, as it allows for large amounts of data to be stored in a compact and portable format.Rate this question:
- 27.
The surface area on a CD is call ________________
Correct Answer
PITS AND LANDS
LANDS AND PITSExplanation
The surface area on a CD is called "Pits and Lands" or "Lands and Pits" because CDs use a digital storage method called "optical storage." This method involves encoding information in the form of microscopic pits and flat areas, known as lands, on the surface of the CD. The pits and lands represent the 0s and 1s of digital data, allowing the CD to store and retrieve information accurately.Rate this question:
- 28.
The surface area on a tape is called
Correct Answer
TRACKS AND FRAME
FRAME AND TRACKSExplanation
The correct answer is "Tracks and Frame". This refers to the surface area on a tape, which is divided into tracks (longitudinal strips) and frames (transverse sections). These tracks and frames store the data on the tape and allow for efficient reading and writing of information.Rate this question:

A scanner is a type of ___________ device
Correct Answer
INPUTExplanation
A scanner is a type of input device because it is used to convert physical documents or images into digital format, allowing them to be stored, edited, or transmitted electronically. Scanners capture the information from the physical document or image and send it to a computer or other device for further processing. As an input device, a scanner allows users to input data or information into a computer system.Rate this question:

Memory Chip is a type of ____________________
Correct Answer
SECONDARY STORAGEExplanation
A memory chip is a type of secondary storage because it is a non-volatile storage device that retains data even when the power is turned off. Secondary storage is used to store data that is not immediately needed by the computer's processor, and it provides a larger storage capacity compared to primary storage (such as RAM). Memory chips, like solid-state drives (SSDs) and flash drives, are examples of secondary storage devices that are commonly used to store data for long-term or permanent storage purposes.Rate this question:
