INTRODUCTIONA computer is an electronic machine that operates by sequentially reading a set of instructions, organized by program, which cause it to execute logical operations on binary numbers. The computer consists of hardware and software. And this study will revolve around hardware components and their interconnection.Computer Diagram1.1 Analyze Hardware Components and Their InterconnectionsThe different hardware components are:1. Power supply unit PSUSpower supply diagramIn a simple sentence, it is a power supply of a computer. The power supply powers all components of the computer. The power supply provides electrical power to all components of the computer. The power supply converts the AC voltage of 12V or 230V into different voltages used by the motherboard and peripherals. All computer components require a power supply, the DVD, the motherboard, the fans, the CPU, the graphics card. They are connected with an AT, ATX connector to the motherboard. The AT and ATXAT layout is a power supply format used for older computers and PENTIUM type computers; ATX is a power supply format used for new computers and PENTIUM type computers. II; is connected to the motherboard..2. CPU/Processor: Central Processing UnitThe CPU is the component of the computer that executes computer programs, it is the brain of the computer. The processor is located inside the computer case on the motherboard. The CPU fits into the CPU socket on the motherboard. Processor speed is measured in MHz (megahertz) and GHz (gigahertz)Motherboard processor diagram3. Motherboard is the main circuit board located inside the computer. All PC components are connected to the motherboard...... middle of paper...... network.14. KeyboardIs the device that allows you to enter information into a computer. Computer keyboards are similar to electric typewriter keyboards but contain punctuation marks and alphanumeric characters. Keyboard Diagram The keyboard is connected to the CPU with two types of connections: 1. PS2, this type of connection is very common for keyboards2. USB, the keyboard is connected to the computer via USB cablePS2 connection diagram and USB15 keyboard. MouseThe mouse is a pointing device for computers. It is made up of an information box to keep close at hand, on which there are one or more buttons and dials in most cases. There are three types of mouse connectors: Wired, wireless and wireless and battery.Diagram of a mouseThe mouse is connected to the central processing unit with the PS2 and USB connection; like keyboard.mouse ps2 connection diagram.
