Introduction to computers by abdul rahaman
This document provides an introduction to computers, covering key topics such as computer components, types of computers, and classification of computers. It defines a computer as an electronic device that processes data according to instructions and can accept input, manipulate data, provide output, and save information. The three main components of a basic computer are the central processing unit, memory, and input/output devices. Computers are classified as analogue, digital, or hybrid based on how they represent and process data. Larger sections cover input/output devices like the mouse, keyboard, monitor, and system unit in more detail.
Peripherals
Peripheral devices are external hardware attached to a computer. There are three types: input devices which produce input signals; output devices which present processed data externally through printing or displaying; and storage devices which store information and documents so they can be retrieved when needed. Examples of storage devices include hard disks, diskettes, CD ROMs, and thumb drives.

Types of input and output devices
Input devices gather information from various sources and translate it into a format understood by computers. Common input devices include keyboards, mice, scanners, and digital cameras. Scanners allow importing of text, graphics, and images, while specialized software helps translate this information.
Output devices display processed information for users. Common soft copy output devices are monitors, which use pixels to display information and connect to computers via graphics cards. Hard copy devices like printers produce physical paper output, with impact printers using inked ribbons and non-impact printers like laser printers forming characters without physical contact. Other output devices include speakers, projectors, and plotters.

components of computer
The document discusses the main hardware components of a computer system and peripheral devices. The core internal components are the motherboard, CPU, memory and storage drives. Input devices like keyboards and mice are used to input data while output devices such as monitors, printers and speakers are used to output data. Peripheral devices are connected externally to the computer and include components like scanners, webcams and external storage drives.
All BAsic Of Ict
Computer hardware includes the physical components of a computer like the CPU, monitor, keyboard, storage drives, graphics and sound cards. The basic hardware components are the central processing unit which directs the system, memory to store programs and data, input devices like keyboards and mice, output devices like monitors and speakers, and secondary storage devices. The lecture describes the functions of the CPU, memory, input, output, and secondary storage devices that make up basic computer hardware.
Input & output unit
Input and output devices allow a computer to communicate with the outside world. Input devices, like keyboards, mice, and cameras bring information into the computer, while output devices, like monitors, printers, speakers, and plotters send information out of the computer. Some input devices require physical operation, like keyboards and mice, while others are automatic sensors, such as barcode readers. Common output devices include monitors to display information visually and printers to produce hard copies.
Hardware
This document summarizes different types of computer peripherals including input, output, and storage devices. Input devices take various forms of input like audio, text, video, and graphics from microphones, keyboards, scanners, webcams, and digital cameras. Output devices display or print the results of processing through monitors, printers, projectors, and speakers. Storage devices hold data electromagnetically for later retrieval, with primary storage like RAM being fast but temporary and secondary storage like hard disks being slower but permanent.
Interacting with your computer
This chapter discusses common computer input devices like the keyboard and mouse. It describes the standard QWERTY keyboard layout and the purpose of different types of keys.

Replication allows data from a MySQL master database to be synchronized with one or more slave databases. The master records all data changes in its binary log. Slave databases connect to the master and receive the binary log transactions, which they then apply locally to stay synchronized with the master database. Replication can be used for load balancing reads across multiple slave servers or for high availability by failing over to a slave if the master fails.

Week-2_CSS9.pptx
This document discusses the key components of computers including hardware, software, and how data flows through a system. It describes common input devices like keyboards, mice, and scanners. Processing is handled by the central processing unit and motherboard. Output devices display or present data through monitors, printers, and speakers. Storage devices temporarily or permanently save data to components like hard drives, flash drives, and optical disks. The document provides examples and functions of the main parts that enable computers to process information.
Present by deepakshi kabra
A computer is made up of different parts called devices that work together to perform tasks. There are three main types of devices: input devices that provide data to the computer like keyboards and mice, output devices that convert information into human-readable formats like monitors and printers, and storage devices that save and retrieve data like hard drives. The central processing unit (CPU) handles intermediate processing and the system unit or tower contains the motherboard, CPU, RAM and other core components.
Input and Output Devices Class V
Input and output devices allow users to communicate with computers. Input devices such as mice, keyboards, and joysticks feed data into computers by translating user actions like clicks, key presses, and joystick movements into electronic signals. Output devices like monitors, printers, and speakers convert electronic data from computers into human-readable forms by displaying visual information on screens, printing text and graphics on paper, and playing sounds from speakers. The document provides examples of common input devices like mice, keyboards, and joysticks and output devices like monitors, printers, and speakers.
Hardware
The document discusses the key components of computer hardware. It defines hardware as the physical components of a computer system, which are further divided into input devices, output devices, and the system unit. Input devices allow entering data into the computer, output devices display or share the data, and the system unit contains the central processing unit, memory, storage, and ports to connect everything. Examples are provided for common input devices like keyboards and mice, output devices like monitors and speakers, and internal components such as the motherboard, CPU, RAM, and hard drive.

Input_and_output_devices.pptx
A computer is an electronic device that can accept data as input, process the data according to instructions, produce output, and store information for future use. It has a central processing unit that executes instructions at high speeds with accuracy. Common computer components include input devices like keyboards and mice, output devices like monitors and printers, memory, storage devices, and software. Networks allow computers to be connected and share resources.
Input nd Output Devices.pptx
Input devices such as keyboards, mice, and scanners allow users to enter data into a computer. Output devices like monitors, printers, and speakers allow the computer to display or communicate processed information to users. Peripheral devices are optional hardware components that are not essential for basic computer functioning. Common input devices use keyboard entry or direct entry to transfer data, while output occurs via visual displays, audio, or physical printouts.
Present by deepakshi kabra
A computer is made up of input devices, output devices, storage devices, and a processing device. Input devices such as keyboards and mice provide data to the computer. Output devices like monitors and printers convert information into human-readable form. Storage devices save and retrieve data either internally or externally. The central processing unit (CPU) handles intermediate processing, and the system unit or tower contains the motherboard, CPU, RAM and other core components.
