Karnataka Board Class 11 Computer Science — Flashcards for Quick Revision

A: A computer system is a computer along with additional hardware and software that work together as a single unit. Main components include: (1) Central Processing Unit (CPU) - the brain that processes d

A: The CPU has two main components: (1) Arithmetic Logic Unit (ALU) - performs all arithmetic operations (addition, subtraction) and logical operations (AND, OR, NOT) as per program instructions, and (2)

A: In ascending order: KB (Kilobyte) < MB (Megabyte) < GB (Gigabyte) < TB (Terabyte) < PB (Petabyte). Each unit is 1024 times the previous unit. For example: 1 KB = 1024 Bytes, 1 MB = 1024 KB, 1 GB = 102

A: Encoding is the mechanism of converting data into an equivalent cipher using specific code. It is important because computers only understand binary language (0s and 1s), so all human-readable charact

A: ASCII stands for American Standard Code for Information Interchange. Key characteristics: (1) Uses 7 bits to represent characters, (2) Can encode 2^7 = 128 different characters, (3) Includes English a

A: D = 68, A = 65, T = 84, A = 65. So 'DATA' in ASCII decimal values is: 68, 65, 84, 65. In binary: D=1000100, A=1000001, T=1010100, A=1000001.

A: Artificial Intelligence (AI) is the simulation of natural human intelligence in machines, making them behave intelligently. Its main goal is to enable machines to perform cognitive functions like lear

A: A knowledge base is a store of information consisting of facts, assumptions, and rules which an AI system can use for decision making. It helps machines make informed decisions based on stored informa

A: Machine Learning is a subsystem of AI where computers learn from data using statistical techniques without being explicitly programmed. It uses algorithms called models that are trained with training
