Input devices allow users to enter data and instructions into a computer. Common input devices include keyboards, mice, scanners, joysticks, microphones, and digital cameras. These devices convert user input into a format that computers can process. Keyboards are the primary input device for entering text. Mice are commonly used to control screen cursors and select items. Scanners are used to digitize images and documents.
Computer hardware includes physical components like the case, monitor, keyboard, and mouse. It also includes internal components like the motherboard, CPU, RAM, hard drive, and power supply. Hardware is anything that can be physically touched. Basic concepts of hardware include input and output devices, as well as components like RAM, the keyboard, mouse, motherboard, hard drive, monitor, and USB flash drives. The CPU carries out computer programs by performing arithmetic, logical, and I/O operations.

This document provides an overview of the main hardware components of a computer, including the monitor, keyboard, mouse, motherboard, main memory, processor, hard disk, floppy disk drive, CD/DVD-ROM drive, video card, sound card, cable connectors, and other peripherals like printers. The motherboard is the main circuit board that connects most other computer parts, while the processor and main memory work together to store and process information for the computer. Input devices like the keyboard and mouse allow users to interact with programs and files stored on storage devices.
The BIOS is the basic input/output system that is built into a computer. It determines what the computer can do without an operating system and is the first software run when a computer is powered on. When turned on, the BIOS initializes hardware components, performs self-tests, and determines which devices can be used to boot the operating system. Modern BIOS also include user interfaces to configure hardware settings and select boot devices.
The document discusses the main components of a computer's central processing unit (CPU). It describes the CPU as containing a control unit that controls the flow of data and instructions, an arithmetic logic unit that performs calculations and logical operations, and various registers for temporary storage of data and instructions. It then provides further details on the control unit, arithmetic logic unit, and different types of registers that make up the CPU.
This document outlines the key components of a computer hardware system. It describes the motherboard as the main circuit board that contains connectors for the CPU, memory, ports, and controllers to interface with peripherals like the monitor, keyboard, and hard drive. Other components discussed include the CPU, RAM, monitor, floppy drive, CD-ROM drive, hard disk drive, and DVD drives. The CPU, RAM, hard drives, and optical drives are described in terms of their functions, speeds, capacities, and costs.

A DVD is a disc that stores digital information such as movies, music, TV shows, and games using lasers and tiny bumps arranged in a spiral track. It was developed by Toshiba, Philips, Sony, and Matsushita Electric and can store much more data than a CD in a different format. DVD players use electricity to power a laser that reads the data on the disc layer by layer. DVDs come in different storage capacities and new formats like Blu-ray can store even more data than early DVDs. The DVD brought digital media storage and playback into mainstream use.
The document discusses several key components of a computer system. It describes the central processing unit (CPU) as the brain of the computer and explains that CPU speed is measured in GHz, with higher speeds allowing more data to be processed. It also discusses different types of memory like ROM, EEPROM, flash memory, and RAM (including SDRAM and DDR). The document outlines internal storage devices like hard disk drives, describing technologies like SATA, PATA, and SSD. It also covers adapter cards, motherboards, and other essential computer parts.

The monitor is the most common output device used to display text and graphics made up of thousands of tiny colored dots called pixels. There are several types of monitors including monochrome monitors that display in black and white, color monitors that can display multiple colors, and LCD monitors which are more expensive but flatter and use less energy than older CRT monitors. The quality of images depends on the screen resolution measured in pixels, with higher resolutions displaying more detail.
