Quiz On Data Representation! Trivia

The given sequence follows a pattern where each number is multiplied by 2 to get the next number. Starting with 32, each subsequent number is obtained by multiplying the previous number by 2. Therefore, the next two numbers in the sequence would be 64 and 128.

The correct answer is 1024. In computing, a kilobyte is a unit of digital information that consists of 1024 bytes. This is because computers use a binary system, where each byte is composed of 8 bits. Therefore, to calculate the number of bytes in a kilobyte, we multiply 1024 by the number of bytes in a single unit, which is 1. Hence, 1 kilobyte is equal to 1024 bytes.

A byte is a unit of digital information that consists of 8 bits. Each bit can have a value of either 0 or 1, representing the binary system used in computers. Therefore, there are 8 bits in 1 byte.

In ASCII, each character is represented by a 8-bit binary code. Therefore, 8 bits are required to represent 1 character in ASCII.

The digits 0-1 are used to store numbers, letters, etc. This is because in binary code, which is the fundamental language used by computers, only two digits, 0 and 1, are used to represent all data. This binary code is then translated into characters, numbers, and other symbols that can be stored and processed by computers. Therefore, the correct answer is 0-1.

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. It uses a 7-bit code to represent a total of 128 different characters, including uppercase and lowercase letters, numbers, punctuation marks, and control characters. Therefore, the correct answer is 128.

A bit is the smallest unit of information in computing and digital communications. It represents a binary digit, which can be either a 1 or a 0. This binary digit is the fundamental building block of all digital data and is used to represent and store information in computers and other digital devices.

ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers. It uses a 7-bit binary code to represent characters, allowing a total of 128 different characters including letters, numbers, and special characters. ASCII is a widely used encoding system and is compatible with most computer systems. It provides a simple and efficient way to represent text in computers by assigning unique binary codes to each character.

The correct answer is "Because it's simple and stops signal degradation". Computers use binary because it is a simple system that uses only two digits, 0 and 1, which can easily be represented by on and off states in electronic circuits. This simplicity allows for easier design, implementation, and troubleshooting of computer systems. Additionally, binary signals are less prone to signal degradation, meaning that the information can be transmitted more reliably without errors.

Bitmap is the correct answer because graphics are represented by the computer using a bitmap, which is a grid of pixels. Each pixel in the bitmap corresponds to a specific color or shade, and together they form the image. Bitmaps are commonly used for representing images in computer graphics and are widely supported by various software and hardware systems.

Real numbers are stored by the computer using a floating-point representation using mantissa and exponent. This representation allows for a wide range of real numbers to be stored and manipulated by the computer. The mantissa represents the significant digits of the number, while the exponent determines the scale or magnitude of the number. This method of representation allows for both very large and very small real numbers to be accurately stored and processed by the computer.
