Precision hardware components have high degree of interchangeability, which means replacing broken or defective components without dismantling equipment is quick and simple. Also they improve performance by speeding up and powering up machines.
The knowledge of computer hardware will equip you to make good upgrades and problem solves, whether you’re a business or consumer user. You will learn the fundamentals of inner computer hardware like CPUs, motherboards and RAM modules in this article.
Motherboard
Motherboards (also known as mainboards, system boards, and mobos) are the control centre for your computer hardware, linking up and passing information through data buses like an executive passing duties to junior employees. Signals to BIOS, SATA and USB from northbridge and southbridge chipset elements wake up CPU, RAM and expansion slots – the structure of your computer.
It is quite easy to expand your computer’s performance with expansion ports such as PCI and AGP connections, and even M.2 SSD slots for super-fast SSDs in motherboards. Moreover, these boards have circuitry for orchestrating the computer work and heat sinks to control the heat from CPUs.
CPU
The CPU (Central Processing Unit) of a computer is the brain that can run software, and send electrical pulses to cause other components of the machine to execute instructions from programs that have been programmed into it.
The control unit has circuitry to transmit data between CPU, memory and other hardware. Its ALU is responsible for all arithmetic and logic computations on instruction operands and registers are high speed storage locations inside CPU where information to be temporarily stored in processor is processed.
Clocks clock out all the intricate circuitry in a CPU with each other, so messing with them to make them go faster could rust parts and void manufacturer warranties. Others try to tinker with them and crank them faster than usual; this quickly wears out parts and invalidates warranty claims.
RAM
RAM (random access memory): It supports real-time application function by being a temporary store. By preventing other parts from going to slower storage systems such as hard drives or solid state drives when users open a new tab in their web browser, RAM makes sure that applications run and people can browse the web smoothly.
The RAM (random access memory) comprises of a series of tiny transistors and capacitors that carry the electrical charge of a data bit; hence the computer’s RAM is much faster at processing data (up to 100 times faster) than the hard disk.
These two kinds of random-access memory (RAM) exist in the computers today: static random-access memory (SRAM) and dynamic random-access memory (DRAM). SRAM does not want to be constantly powered, so it is more expensive. DRAM isn’t always powered on but it must be re-used often, so it won’t run perfectly at all.
Hard Drive
Hard drives are the most complicated part of any computer, but also the most stable part of any computer. It can be found on PCs, servers and phones – hard drives are dropped and kicked about without ever giving out. But they work perfect most of the time.
Digital data is held on platters, which are disks of various sizes, whose surface is made up of thousands of small bits that take up an electric charge. These ones and zeroes are reached by an HDD’s read/write heads by magnetically attaching to some of the platter’s axes and measuring their magnetic direction.
The head moves by way of an actuator unit. It works by moving an arm through a voice coil motor and that arm then travels over spinning platters.
Video Card
A Video Card or Graphics Processing Unit or GPU is one of the most important pieces of Computer hardware. Because of its parallelism, applications can be found in gaming and video editing software to artificial intelligence systems.

GPU life is like any hardware, it is tied to the usage rate and intensity. Once one is no longer needed or lagging, replacement or upgrade is available; usually for PC-skin performance improvement or docking outboard GPUs into boxes for ease of use.
