• The CPU is the brain of the computer.
• It performs arithmetic, logic operations, and control functions.
• Hardware and software are the two main components of any computer system
• Hardware is the physical part of a computer that is tangible and can be touched
• Software is used to control the computer and process data
• Hardware is divided into two categories: external hardware and internal hardware
• Internal hardware includes components like the motherboard, central processing unit (CPU), random access memory (RAM), read-only memory (ROM), graphic card, sound card, network interface card, and internal storage devices
• External hardware includes devices like hard drives, keyboards, mice, cameras, monitors, printers, plotters, scanners, and speakers
• Input devices and output devices are two subcategories of hardware
• Software consists of a set of rules or instructions to perform tasks and is divided into application software and system software
• Application software includes word processing, spreadsheet, database apps, video editing, audio editing, graphic editing software, and computer-aided design (CAD) programs
• System software includes compilers, linkers, device drivers, operating systems, and utilities
• The operating system is essential for the computer to function and allows users to interact with the system
• The operating system controls input/output devices, supervises application programs, maintains computer security.
• Types of computers include desktop computers and mobile computers, with examples like laptops, smartphones, tablets, and phablets
• Emerging technologies like artificial intelligence, augmented reality, and virtual reality are still in development stages and aim to enhance user experiences and capabilities
