INTRODUCTIONA computer is an electronic machine that works by sequentially reading a series of instructions, organized by program, which make it perform logical operations on binary numbers.The computer is made up of hardware and software.And this study will deal with hardware components and their interconnection.Computer Diagram1.1 Analyze hardware components and their interconnectionsThe different hardware components are:1. PSU Power Supply UnitPower Supply DiagramIn a simple sentence it is the supply of a computer. The power supply supplies power to all components of the computer. The power supply supplies electricity to all components of the computer. The power supply converts AC voltage of 12V or 230V into various voltages used by the motherboard and peripherals. All computer components require electricity, DVD, motherboard, fans, CPU, graphics card. They connect with an AT, ATX connector to the motherboard. Diagram of AT and ATXAT 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 programs, it is the brain of the computer. The CPU is located inside the computer case on the motherboard. The CPU fits into the motherboard's CPU socket. CPU speed is measured in MHz (megahertz) and GHz (gigahertz)CPU diagram in the motherboard3. MotherboardIt is the main printed circuit board found inside the computer. All components of the PC are connected to the motherboard... the center of the card... network.14. KeyboardIt is 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 central unit 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 a USB cable PS2 and USB keyboard connection diagram15. MouseThe mouse is a computer pointing device. It is made up of a box to keep at hand, on which there are one or more buttons and in most cases a dial. There are three types of mouse connectors: wired, wireless, and wireless and battery. Diagram of a mouse The mouse is connected to the central unit with the PS2 and USB connection; like the keyboard.Mouse PS2 connection diagram.
