Computers Python Basics
Computers and Components A computer is a device that processes data and follows instructions called programs. It includes hardware like the CPU, memory, storage, and input/output devices. Programs and Programming Languages Program: A program is a set of commands that tells the computer what to do. Programming Language: A programming language helps developers give instructions to the computer in a standard way. Machine Language Computers are made of transistors, which can either stop or allow electricity to pass through. 0 (Low) means no electricity passes, and 1 (High) means electricity passes. Machine language is made up of 0s and 1s, which is the only language a computer can understand. Everything you see on a screen comes from these 0s and 1s. For example, “HELLO” in binary looks like: H → 01001000 E → 01000101 L → 01001100 L → 01001100 O → 01001111
