Computer

1. Hardware

   • Hardware includes not only the computer proper but also the cables, connectors, power supply units, and peripheral devices such as the keyboard, mouse, audio speakers, and printers.
     • CPU
       • Optical disc Drive
         • Optical drives retrieve and/or store data on optical discs like CDs, DVDs, and BDs (Blu-ray discs), any of which hold much more information than previously available portable media options
       • PC Case
       • Power supply unit
         • It converts the alternating current (AC) into a continuous form of power that the computer components need in order to run normally
       • Hard drive
         • Non-volatile memory hardware device that permanently stores and retrieves data on a computer.
       • Mother board
         • Microprocessor
           • It contains all, or most of, the central processing unit (CPU) functions and is the "engine" that goes into motion when you turn your computer on.
         • Ram memory
           • It's the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device's processor. Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data.
         • BIOS
           • BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on.
         • Chipset
           • It's a group of integrated circuits (microchips) that can be used together to serve a single function and are therefore manufactured and sold as a unit.
         • Connectors
           • Internal
           • External
             • USB
               • A Universal Serial Bus (USB) is a common interface that enables communication between devices and a host controller such as a personal computer (PC).
     • PERIPHERALS
       • Input
       • Output
       • Storage

2. Software

   • Operative systems
     • It's a software program that enables the computer hardware to communicate and operate with the computer software.
   • Apps
   • Drivers
     • A driver acts like a translator between the device and programs that use the device. Each device has its own set of specialized commands that only its driver knows.
   • Firmware
     • Software (programs or data) that has been written onto read-only memory (ROM). Firmware is a combination of software and hardware.
