Lec 2 / working of computer / JKSSB SSC...

A computer works by taking raw data (Input), storing and processing it based on instructions (CPU), and delivering results (Output). Think of it as a four-step cycle: Input (typing/clicking), Processing (CPU analyzing data), Storage (saving data), and Output (displaying on screen). This entire process is driven by software and executed using electricity. Simple Step-by-Step Process: Input (Receive Data): You provide data via keyboard, mouse, or microphone, which the computer converts into digital signals. Storage (Save Data): The computer holds this data in memory (RAM) or on a hard drive to work on it. Processing (CPU): The Central Processing Unit (CPU) acts as the brain, fetching, decoding, and executing commands (calculations, logic) to transform data into information. Output (Show Results): The processed information is presented on a screen, printed, or sent as audio.
