Computer system are very complicated, but they’re also made up of smaller pieces. These components can be broken down into three categories: the system unit, input/output devices, and power supplies. The system unit is the core of your computer. This usually consists of a motherboard and a set of processors (CPUs). The CPU is an electronic device that processes all the information that comes into it. There can be multiple CPUs on a single motherboard depending on how powerful your computer needs to be. For example, an average home computer would have one or two CPUs while a server would have eight or more!
The CPU (Central Processing Unit) is the brain of your computer. It’s where all the processing takes place and it does this by following instructions from programs stored in memory. The more cores you have on your CPU, the more instructions can be processed at once. This makes for faster performance when working with large files or running multiple applications at once. The most important part of any computer system components is its processor, and that’s why we’re starting off with one!
The power supply unit (PSU) is a device that converts AC power into DC power and distributes it to the various computer system components of the computer. It is a box-like metal enclosure, usually black, with a fan at the top and cables coming out of the back.
The PSU contains several transformers which step down high voltage AC current from your electrical outlet down to lower voltages required by your computer’s internal components, such as 5 volts DC for USB ports or 12 volts DC for fans in laptops and other devices that use them, and then converts it into alternating current (AC).
RAM is the memory that your computer uses to run programs and store data. The more RAM you have, the more information can be processed at once. RAM is volatile, which means it loses its data when the computer is turned off. It doesn’t need to be plugged in or charged like a battery; it just needs power from your outlet to work properly. The amount of RAM within any given system is measured in gigabytes (GB) or terabytes (TB), depending on how much information needs to be stored on it at any given time.
The hard drive is a non-volatile storage device. A hard drive stores data on magnetic disks (also called platters) that rotate at high speeds. The rotating platters are driven by a motor and controlled by read/write heads mounted on arms that move in and out over the surface of each platter. When you save information on your computer’s hard disk, it’s actually being recorded magnetically on one or more of these spinning magnetic disks inside your computer case.
When you want to access this information again, your PC reads it back from its memory chips into its own RAM memory as if it were loading off an imaginary tape cassette; then after processing what’s needed for whatever task was requested, such as displaying text or playing music, it writes back down onto another part of those same magnetic surfaces so nothing gets lost when power is removed from those components during shutdowns/reboots etcetera!
An optical drive is a device that reads data from and writes data to CDs, DVDs, or Blu-ray discs. It can also read CDs or DVDs to install software and save files on them. CD/DVD ROM Drives are used in most computers today because they are cheap and easy to use. They are no longer as fast as they used to be due to competition from newer technologies such as USB flash drives, but they still provide an excellent way of storing large amounts of data with minimal space requirements (compared with hard drives).
A CPU is the central processing unit of a computer, which is responsible for carrying out all instructions. The CPU takes data from memory and processes it, before writing the results back to memory or sending them over to another component such as an output device.
A power supply unit (PSU) converts mains electricity into direct current (DC) power that can be used by components in your computer system. A PSU usually has multiple connectors with different voltages ranging from 3 volts up to 12 volts DC or even more depending on its purpose and design, some PSUs include auxiliary connectors that allow you to connect additional peripherals or accessories such as fans or lights directly into them without needing separate cables! Memory refers to any kind of storage device used by computers including RAM (Random Access Memory), ROM (Read Only Memory), hard drives etc.
