The components that make up a computer are called hardware. These include motherboard, CPU, RAM, and hard drive.
Aside from the hardware that performs basic computations, certain pieces of computer hardware also play an important role in overall system health. These include power supplies and cooling units.
Motherboard
The Motherboard is a vital part of pc hardware that enables communication and coordination between different components. It houses the CPU and provides connections for other peripheral devices such as printers, keyboards, and mice.
It also has slots for expansion cards that add additional features and functions to the system. The motherboard also has connectors for storage devices like magnetic hard drives and optical drives.
The motherboard contains a number of essential components such as processor sockets, RAM slots, CMOS battery, and BIOS. It also has a USB port, which allows computers to connect to other devices and transfer data.
CPU
A computer’s CPU (Central Processing Unit) is its brain and handles all the instructions it receives from programs and other hardware in the system.
A CPU is made up of a large number of integrated circuits on a single rectangular chip. These chips are manufactured using millions of tiny components called transistors and are built from semiconductor material, or silicon.
The processor chip is placed in a special socket on the motherboard. These sockets are designed to support specific form factors of Intel or AMD CPUs, based on the pin layout on the CPU.
The CPU also includes a memory bus that temporarily stores active programs and data in RAM. This means that the CPU doesn’t have to go out to the hard drive when it needs the information, thereby speeding up the computer boot process.
RAM
RAM or Random Access Memory is a type of Computer Data Storage that stores temporary data that Programs use in their operation. It has fast write and read speed, therefore makes the Programs work faster.
The amount of RAM in your PC will depend on the number of programs you run, and the types of applications you use. 4 GB or 8 GB are generally enough for most average users, but more memory is needed for heavy usage, such as programming and gaming.
RAM is usually stored in microchips, and it plugs into slots on your motherboard. Most PCs allow you to add up to a certain number of memory modules.
Hard Drive
Hard drives are the primary long-term storage device for computers. They store information magnetically, and keep it even when a computer is turned off.
A hard drive contains small round disks called platters coated with a special coating that allows them to store data magnetically. As the disks spin (typically at 5,400 or 7,200 revolutions per minute), an actuator arm moves across them to read and write data.
The size of a hard disk can range from several hundred megabytes to terabytes. Older solutions have smaller capacities, while newer ones offer much greater storage space.
Optical Drive
The Optical Drive is a part of computer hardware that allows you to read and write data on CDs, DVDs and Blu-ray discs. It’s an important component of a PC because it can save you space and time by using the laser technology to store data rather than magnetic storage media.
Optical drives are based on the laser technology that’s much faster than traditional magnetic drives. Optical discs are inserted into an optical drive at a constant speed (calculated in revolutions per minute, or RPM) and a laser beam is used to read the disc’s data.
Tower
A computer tower is a case that houses many components of a desktop PC. These cases can be shaped in a variety of ways, and they may include multiple drive bays and other features.
The tower form factor is a popular choice for personal computers. It tucks neatly under desks and offers ample room for upgrades.
Towers are also an option for businesses that want to add more power to their servers. Often, these machines feature advanced processors, memory, and graphics cards that are more powerful than those found in traditional desktop PCs.
