- 2. Notes on Class 1 How does Computer parts work? CPU: The brain of a computer system is the central processing unit of a computer system. The CPU is in charge of processing all operations and sending commands to the computer. A faster processing system is aided by a more powerful CPU. Ram: RAM (Random Access Memory) is a computer component that stores data utilized by the operating system and software applications so that the CPU can process it rapidly. If the computer is turned off, everything saved in RAM is lost. There is usually a maximum amount of RAM required for the computer to perform effectively, depending on the apps you use. Storage Space:There are two options for Storage Space. It can be either Hard Disk Drive (HDD) or Solid State Drive (SSD). The use of HDD has become old that includes storing data on a disk, which is a slower process. SSD is the new storage type that stores data on a memory chip, and it is a faster process. Motherboard: There is no acronym for this component, but a computer would not bepossiblewithout it. All other components havea home on the Motherboard, which allows them to communicate with one another and provides them with the power they need to work. There are some components that do not require a physical connection to the Motherboard to function, such as Bluetooth or Wi-Fi, but if there is no connection or signal, the computer will be unaware of its presence.
- 3. Graphics Card: The graphics card is a piece of computer hardware that is responsible for rendering images on the monitor or display screen. Network Card:Your computer's network card enables it to interact over a network and connect to the Internet. It can connect via either an Ethernet cable or a wireless link (often called Wi-Fi). Many motherboards have network connections built in, and a network card can be installed to an expansion slot as well. Bluetooth Card: Bluetooth is a wireless communication technology that works across short distances. It's commonly used to communicate with wireless keyboards, mouse, and printers in PCs. It's usually present in a wireless network card or built into the motherboard. A USB adaptor, often known as a dongle, can be purchased for computers that do not have Bluetooth.
