About the computer
The document discusses the history of various computing components and devices. It describes the abacus as one of the earliest tools used for computation dating back to 2700-2300 BC. It then provides details on key computer components including the central processing unit, monitor, keyboard, mouse, motherboard, computer speakers, printer, and laptop. It also discusses early handheld computing devices.
Digital technology
Digital technology uses electronics, devices, and equipment that operate using binary logic and discrete signals. Examples include computers, digital cameras, MP3 players, mobile phones, and other devices that store and process digital information. A computer takes in information as input, processes it, and produces new output. Digital cameras store photos digitally on memory cards instead of film. MP3 players allow users to listen to music files in a portable format. Mobile phones allow wireless communication over long distances by connecting to nearby cell towers and handing off calls between cells as the user moves around. Many modern mobile phones are smartphones that provide additional functions beyond calls like email, apps, internet access, and cameras.
Usb connector
A USB connector is used to connect peripheral devices like printers, keyboards and mice to computers. It was developed to simplify the connections between devices, which previously used many different proprietary connectors. The USB connector provides benefits like plug-and-play capability, supporting many device types through a single interface, auto-configuration, increased data transfer speeds, and lower production costs.

It discusses the central processing unit (CPU), random access memory (RAM), read only memory (ROM), hard drive, CD-ROM drive, floppy drive, power supply, various connectors, sound card, video card, network card, modem, and serial port. It describes the basic functions of each component and how they connect and interact with each other to allow the computer to perform calculations and tasks.
Innovative Business Models Presentation
This document proposes a wireless sensor network system to detect vacant seats in large auditoriums. The system would attach a sensor unit containing a pressure sensor, microcontroller, and WiFi module to each chair. These sensor units would send data to a central server about occupancy. The server would then display available seats on a screen and mobile app, helping attendees find empty seats without disturbing others. The system aims to be cost-effective at 50% cheaper than competitors while offering real-time tracking of vacant seats anywhere in the auditorium through an identifiable sensor network. It could be marketed to venues like airlines, stadiums, and auditoriums globally.

EDP hardware
Computer hardware includes input devices, output devices, and storage devices. Input devices such as mice, keyboards, and webcams allow users to input data. Output devices like monitors, printers, and speakers allow the computer to output information to the user. Storage devices such as USB drives and diskettes are used to store data on the computer.
Educational technology
There are many external devices that can connect to a computer, including a mouse, keyboard, monitor, microphone, and speakers. These devices connect via ports on the computer system unit, which houses the primary components like the motherboard and CPU. USB and FireWire ports are commonly used because they allow for hot-plugging, meaning devices can be connected and used immediately without restarting the computer.
Lesson4 Buttons, Sockets, Slots
The document discusses the various buttons, slots, and ports found on computers and their functions. It describes common features like the power button, CD/DVD drives, USB ports, audio ports, expansion slots, and peripheral ports. Specific ports are meant for connecting keyboards, mice, printers, scanners, speakers, microphones, webcams, and more. Being familiar with the names and uses of these ports will help the user connect different devices to their computer.
Introduction to Computer - Idowu A.J. Odeyemi.pdf
The document provides an introduction to computers including definitions and examples. It discusses that a computer accepts data as input, processes it, and provides output. It then describes the basic components of a computer including hardware (central processing unit, memory, peripherals), software (operating systems, applications), and human users. The document outlines input devices like keyboards and mice, output devices like monitors and printers, and storage devices like hard drives. It provides examples of common computer components and their functions.

Input and output
- 1. Input and Output Chapter 4 technology
- 2. What is Input? Input devices are any of the various devices used to enter, or INPUT, information into a computer for storage or processing. These devices are usually plugged into the front or back of the tower through the use of UBS ports.
- 3. Various Input Devices There are many different types of input devices. There are several very important devices that are used with a computer: Keyboard Pointing devices – mouse, trackball, touchpad, touch screen and pen inputs.
- 4. USB Ports A USB port, or Universal Serial Bus port, is a standard cable connection interface on personal computers and commercial electronics. They allow stand-alone electronic devices to be connected to a computer or to each other. Before USB ports, computers used serial ports and parallel ports to connect devices to a computer. Zip drives usually used the parallel ports as did printers which would limit the use of both.
- 5. USB Ports The goal of the USB port is to end all of the confusion for input ports. The USB port gives us a standardized, easy-to-use way to connect 127 different devices! Some devices that use USB ports are: printers, scanners, joysticks, mice, keyboards, digital cameras, webcams, modems, speakers, and storage devices. Besides connecting devices, USB ports can also supply electrical power to devices.
- 6. What is Output? Output devices are computer components that are capable of conveying, or OUTPUTTING, information from the computer to the user. Output is basically anything that comes out of a computer. This can include data, texts, pictures, videos, or sound.
