A segment of a track in a mass storage system
- A.
Pixel
- B.
Address
- C.
Sector
- D.
Flip-flop
Correct Answer
C. SectorExplanation
A sector refers to a specific portion or segment of a track in a mass storage system. It is a standardized unit of data storage that typically contains a fixed number of bytes. Sectors are used to organize and store data on storage devices such as hard drives and solid-state drives. Each sector is assigned a unique address, allowing the system to locate and retrieve data efficiently.Rate this question:

A numeric value used to identify a memory cell
- A.
Hexadecimal notation
- B.
Boolean operation
- C.
Bit
- D.
Address
Correct Answer
D. AddressExplanation
An address is a numeric value used to identify a memory cell. It serves as a unique identifier for each memory location. In computer systems, memory is organized into cells, and each cell has an address associated with it. This address allows the computer to locate and access specific memory locations for reading or writing data. Therefore, the correct answer in this case is "address."Rate this question:

A means of encoding text in which each symbol is represented by 16 bits
- A.
ISO
- B.
ASCII
- C.
Unicode
- D.
LZW
Correct Answer
C. UnicodeExplanation
Unicode is the correct answer because it is a means of encoding text in which each symbol is represented by 16 bits. Unicode is a universal character encoding standard that can represent characters from all major languages and scripts around the world. It allows for the representation of a wide range of characters, including those from different writing systems, symbols, emojis, and special characters. The use of 16 bits ensures that a large number of characters can be encoded, making it suitable for multilingual and international applications.Rate this question:

Which of the following storage systems is best suited for storing and retrieving long strings of data that are processed in their sequential order?
- A.
Magnetic disk
- B.
Main memory
- C.
Optical CDs and DVDs
Correct Answer
A. Magnetic diskExplanation
Magnetic disks, such as hard drives, are well-suited for storing and retrieving long strings of data that are processed in their sequential order. This is because they allow for both sequential and direct access, making them versatile for various data operations. Please note that while main memory and optical CDs/DVDs can also store and retrieve data, they may not be as efficient as magnetic disks for handling long strings of data in sequential order.Rate this question:

Which of the following bit patterns (represented in hexadecimal notation) represents a negative number in two’s complement notation?
- A.
55
- B.
7F
- C.
A6
- D.
08
Correct Answer
C. A6Explanation
In two's complement notation, the most significant bit (MSB) represents the sign of the number. If the MSB is 1, it indicates a negative number. In hexadecimal notation, A6 has a binary representation of 10100110. Since the MSB is 1, A6 represents a negative number in two's complement notation.Rate this question:

A digital circuit capable of holding a single digit
- A.
Pixel
- B.
Bit
- C.
Key field
- D.
Flip-flop
Correct Answer
D. Flip-flopExplanation
A flip-flop is a digital circuit that can store and hold a single bit of information. It is commonly used in digital systems for memory storage and synchronization purposes. In this context, a flip-flop can be used to represent and hold a single digit, pixel, or key field, making it the correct answer.Rate this question:

A major standardization organization within the United States
- A.
LZW
- B.
ISO
- C.
ANSI
- D.
ASCII
Correct Answer
C. ANSIExplanation
ANSI stands for the American National Standards Institute, which is a major standardization organization within the United States. It develops and publishes voluntary consensus standards for a wide range of industries, including technology, manufacturing, and safety. ANSI works to ensure that products, processes, and services are safe, reliable, and of high quality. Therefore, ANSI is the correct answer as it aligns with the given description.Rate this question:

Which of the following bit patterns represents the value 5 in two’s complement notation?
- A.
11111011
- B.
00000101
- C.
11110011
- D.
00011010
Correct Answer
B. 00000101Explanation
The bit pattern 00000101 represents the value 5 in two's complement notation. In two's complement, the leftmost bit is the sign bit, indicating whether the number is positive or negative. A 0 in the sign bit represents a positive number, while a 1 represents a negative number. The remaining bits represent the magnitude of the number. In this case, the sign bit is 0, indicating a positive number, and the remaining bits 00000101 represent the magnitude of 5.Rate this question:

A means of compressing images by blurring the boundaries between different colors while maintaining all brightness information
- A.
JPEG
- B.
LZW
- C.
MIDI
- D.
GIF
Correct Answer
A. JPEGExplanation
JPEG is a method of compressing images by blurring the boundaries between different colors while preserving the brightness information. It achieves this by using a lossy compression algorithm that discards some of the less important image details. This allows for significant reduction in file size without significant loss in image quality, making JPEG a widely used format for storing and transmitting photographic images on the internet.Rate this question:
