Computer structure was first written in 1945 by John Von Neuman. Input > Processor > Output > Storage > Feedback(human) Input devices – keyboard, mouse, microphone, sensors, document or visual scanners. Processing – CPU, control unit, processor, arithmetic or logic unit, and memory component. Storage – primary/long term memory(hard drive) and temporary memory(RAM), Other storages such as USB, flash drive, optical discs, or floppy disk. Output – Internal storage devices or processes, monitor screens, speakers, and printers Feed back(Bus system) – is the medium through which communication occurs. Connection and data transfer between computer are called bus and the internal bus connects motherboard to CPU. The motherboard, or similarly the backplane, of a system is the device that contains the system bus and connects the various input and output devices that compose any given computer system. Network interface cards allow computers to connect to networks. A server manages network resources and services, while routers are used to link networked computers so they can share resources and information.

Input devices: Punch card, magnetic readers, voice recognition, keyboard input, touch sensitive screen, biometric scanners, motion detection, document scanner, cameras, facial recognition, RFID tracking, barcodes and wireless sensor networks. Output devices: Document printer(Laser jet, dot-matrix, termal transfer), speakers, monitors and TVs, computer aided equipment, document printer. Hybrid input/output devices: Modem(network device), touch screen monitors and tablets, virtual reality goggles, augmented reality, or computer assisted virtual environments. Processor: Central processing unit(CPU) known as the brain of the computer, is one of many component that makes a computer run. Modem CPU Are electrical devices that flows one direction. CPU are installed on the motherboard socket, within the CPU there are pins that allows connection to a single bit(serial processing) to enter in or exit from the processor. Each bit is either on or off and, taken together, allows a computer to process instructions. Single bit are made of 8 bits that is either letter or number Connection between CPU, memory, storage, expansion slots, and motherboard is called the system bus that carries data between each device. Due to today’s innovation processors can support multiple task from multiple applications in a parallel data stream.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
