Computer Science

Laser printers are designed for high-volume text printing due to their fast speed, high-quality output, and cost efficiency compared to inkjet or daisy wheel printers. Digital plotters are used for large-scale graphics, not high-volume text.

Inkjet printers are known for producing high-quality graphic prints with good color accuracy and detail, making them suitable for graphic printing. Digital plotters are typically used for large-scale line drawings and CAD designs, not for high-quality graphic printing.

A binary number consists only of the digits 0 and 1. Among the options, only '1001' contains exclusively 0s and 1s, making it a valid binary number. The others contain digits 2, 5, or 6, which are not valid in binary representation.

ANSI stands for American National Standards Institute, which is the correct full form among the options provided. It is a private non-profit organization that oversees standards for products, services, processes, and systems in the United States.

A half-byte consists of 4 bits and is commonly known as a nibble in computer science. This term is standard and widely accepted.

A bit is the smallest unit of data storage in computing, representing a binary value of 0 or 1. Nibble, byte, and megabyte are larger units composed of multiple bits.

One Megabyte (MB) is commonly defined in two ways: the decimal definition where 1 MB = 1,000,000 bytes (10^6 bytes), and the binary definition where 1 MB = 1,048,576 bytes (2^20 bytes). The binary definition is often used in computer memory contexts and corresponds to 1024 Kilobytes (KB), where 1 KB = 1024 bytes. Therefore, one Megabyte is equal to 1024 Kilobytes, not 1024 Bytes. Option B (1024 Kilo Bytes) is the correct answer in the binary context, which is the common usage in computer science for memory sizes. Option A (1024 Bytes) is incorrect because 1024 Bytes equals 1 Kilobyte, not 1 Megabyte. The other options are incorrect or incomplete.

EBCDIC (Extended Binary Coded Decimal Interchange Code) uses 8 bits per character, allowing for 256 possible character codes. This is why the correct answer is 8 bits.

A 'bit' stands for 'binary digit,' which is the most basic unit of data in computing, representing a 0 or 1. Therefore, the correct term for 'bit' is 'Binary Digit.'

In the binary system, the values are 0 and 1. Typically, 0 represents a low voltage or off state, while 1 represents a high voltage or on state. Therefore, 0 corresponds to 'Low'.
