6a. Draw and label the basic block diagram of a computer system. b. Briefly explain the functions of: (i) Input Unit (ii) Central Processing Unit (CPU)

Here are the answers to your questions: a) The basic block diagram of a computer system illustrates the fundamental components and their interconnections. Basic Block Diagram of a Computer System Input Unit Central Processing Unit (CPU) Memory Unit Output Unit The Central Processing Unit (CPU) itself consists of: • Control Unit (CU): Manages and coordinates all operations of the computer. • Arithmetic Logic Unit (ALU): Performs arithmetic operations (addition, subtraction, etc.) and logical operations (comparisons). b) Here are the functions of the specified units: i) Input Unit The input unit is responsible for accepting data and instructions from the user or external sources. It converts this human-readable information into a machine-readable format that the computer can process. ii) Central Processing Unit (CPU) The CPU is the "brain" of the computer, responsible for executing instructions, performing calculations, and managing all other components. It processes data, controls the flow of information, and carries out arithmetic and logical operations. iii) Memory Unit The memory unit stores data and instructions that the CPU needs to access quickly. It holds programs currently being executed and the data they are operating on, allowing for fast retrieval and storage of information. iv) Output Unit The output unit displays or presents the processed results from the computer to the user in a human-readable format. It converts machine-readable data into text, images, audio, or other forms that humans can understand. Send me the next one 📸
