What’s Inside My Computer – Different Components Of A Computer

A computer is made up of different components like the motherboard, processor, display, RAM, etc. Each component has to do its own set of careers in coordination with other parts to make the PC function properly. Let’s see what’re the internal components of a PC.

It’s a standard question that pops up in the head of nearly every PC person who’s in the method of getting with their machine. The same thing also happened to me. And very few consumers are able to build the courage to unscrew their device and see what’s inside their PC. I was one such individual.

It was one day after I borrowed a friend’s screwdriver set to open my laptop, a Dell Inspiron N5010. Just like me, a lot of the folks who actually build the nerves to open up their laptop don’t feel much about the consequences of the experiment they are planning to perform.

I also ended up leaving one of the important components unscrewed during the closing procedure. Thankfully, I am writing this article on the same Inspiron N5010 which was once a subject of my tech experiment. I did strip down my laptop several times.

In this article, I ‘ve tried to put the very best of my knowledge in regards to the elements of a PC and this is my solution to the issue,


The basic building block of a computer, whether it’s a laptop or a desktop, is a green-colored printed-circuit-board called Motherboard. All the other elements are linked to it and use interfaces and various circuits to talk with each other. For a desktop computer, you have to open one screw so that you can gain access from what is inside the computer. However, to get a laptop, it’s tiresome and frightening career.

Motherboard Properties numerous parts like memory slots, sockets, chip-set, clock generator, expansion slots, storage connectors, etc. I ‘ve currently coated the parts of a motherboard in one of my previous writings. You are able to read it by clicking the web link below.


You might have heard it an uncountable quantity of that time period a processor or a CPU (Central Processing Device) is the brain of a computer. Often, in the case of desktops, people confuse the CPU with the cabinet.

A microprocessor homes the two parts of processing unit, a processor, and the control unit, for a passing fancy tiny IC. Modern microprocessors come as multi-core or single-core. A multi-core micro Processor like the Intel Core I-7, have over one processing models (cores) current on a single chip.

The basic task a processor has to perform might be divided into three categories:

•It gathers the required program information to be processed. For this, the data is shifted to the CPU to the RAM of the computer than from the hard push.

•The data is then processed by the CPU on the foundation of regulations and some guidelines, recognized as Coaching Established, it currently understands
•The processed information is prepared. It then follows the measures the programmer has incorporated in the program. As an example, the processed info saved to the hard push or could be displayed on the display.


Cache memory contains the data which can be often required by means of a CPU just like the plan directions. Then going for the larger types, it’s easier for the CPU entry the cache memory first. Cache memory is way quicker than RAMs thus it’s costlier. So, the size of the cache memory is stored limited.

The cache memory is present on the CPU chip itself.

Memory comes in ranges like L 3 cache, L2 cache, and L 1 cache. The CPU first looks for the necessary info in L-1, then L2, then L-3, and L4 if it exists. Finally, if not one of the cache recollections is able to supply the info that is required, the RAM will be accessed by it. Cache memory is extremely important to a computer. A processor with increased cache will not perform worse than a computer using less cache and a quicker processor. But this doesn’t mean that A – 20-year-old processor puffed with excess cache could outperform something special day processor.


Random Access Memory is among the essential elements of a PC. In the event that you consider out the RAM chip from the computer, it won’t begin. It’s quicker compared to drives that are hard and is used to retailer the CPU program information which is currently utilized by the CPU. But RAM is affected with quick -term memory reduction. What exactly does it imply? When it receives energy, it holds info only. All of the data is going to be lost after you change your computer off. That’s the reason it can’t be utilized as a permanent storage solution for a PC.

The reason why is to make the memory chip compact for the laptops. However, they have powers and the same features. Dynamic RAM integral circuits, known as Twin-Inline Memory Module (DIMM), are mounted on green-colored PCB and after that called as DIMM chips. Memory variants like DDR, DDR2, DDR3, DDR4, etc. differ in a number of pin counts they’ve.

Before DIMMs, SIMMs used to exist. The key distinction involving the two is a number of pin counts. SIMMs have half the quantity of pins than DIMMs. If you simply take a casual look on them the number of pins will appear the same. An eager observation would lead to a conclusion the pins on either side of a SIMM are attached to every other which is not true with DIMM.

The SIMM supports A – 32-bit data bus while DIMM supports 64-bit info bus. This enables the flow of moRe info in the case of DIMM. The contemporary 64 bit CPUs would require an installation of two SIMMs chips.A single DIMM would be sufficient for that. The SIMMs became obsolete with time.


The Basic Input/Out-Put Program (BIOS) is accountable for beginning your computer. It checks that all of the components are linked are functioning fine. It loads the operating system. It also behaves as the operating system along with a middleman between and the hardware components of the computer.

BIOS is actually a firmware (computer software) which can be stored possibly on a nonvolatile memory chip current on the motherboard. The chip is EEPROM which the data can be rewritten or a flash memory chip when the power is slice the by us, unlike the normal RAM, but it stays intact. This facilitates the effortless upgrade of the BIOS firmware.

BIOS is specific to various computers. Like, a BIOS created to get a Dell PC won’t be supported by means of an H-P computer. Should you install a non-supported BIOS on a machine, it might lead to components failure. It really is so specific that even should you install the BIOS of a different type of the same maker, you could end up burning your motherboard.

UEFI (Unified Extensible Firmware Interface) could be called the continuing future of-of the BIOS. It provides better security and is more high level. As UEFI is not implemented over the planet, however, most manufacturers nonetheless supply support for UEFI and BIOS using their machines.

Storage Memory:

It’s a huge and permanent space for storing which can be used to keep each of the data required by means of a computer such as the operating system files, songs, videos, and third-party software documents, etc. When needed, the data is transferred from the difficult push to the random-access memory for being utilized by the CPU.

This memory can be quite a magnetic rotating hard disk drive (HDDs) or a Solid State Drive (SSD). Hard Drive is typical than the SSDs that are newer as they are cheap but SSDs are quicker. These HDDs and HDDs attached to through the S-ATA interface to the computer -based storage connectors current on the motherboard.

Electronic Visible Display:

It’s an output system connected to a computer which shows the preferred graphics output produced by the graphics processing unit of the PC. Generally known as a monitor, a PC display can be an LCD (Liquid-Crystal Show) centered or LED (Light-Emitting Diode) centered.

For desktop computers, the exhibit unit remains independent compared to the remaining computer components. Desktop computers are of good use for long usage schedules. Having a split up monitor makes the replacement method more easy if something goes wrong using the display.

For laptops and netbooks, the display unit is separate but connected to the chassis housing the computer elements of making it, for the cause. This adds to the mobility and ease offered to the consumer. These displays use a different type of video cable to attach to the motherboard. AIOs provide best of both worlds by supplying the PC elements along with the show in the same body.

You might maybe not know that the ‘Refresh’ alternative in Microsoft Windows actually concerns with the display not the CPU or memory of the computer. Read the following article to know more:

Optical Disk Drive

These are used to read media like DVDs and Blu-Ray discs. It comprises of a lens which a helps light to be thrown by a laser beam on the written info in a sequence that is present. The mirrored mild is captured by photodiodes.

Desktops generally include a tray-load sort optical disk drives while the notebooks have a slot-load sort optical disk drives. These disk drives are capable of studying and composing info to a media.

Graphics Processing Unit

It processes the related data which is to be shown on the monitor. GPUs could be integrated directly into the motherboard. They also come with individual graphics processors which may be connected to your computer utilizing the PCI slot present on its motherboard.

The integrated graphics processors use the RAM installed on the PC while the discrete graphics cards come with their own RAM (recognized GDDR or video memory), a separate power, and cooling system. This makes them quicker and more reliable in relation to the graphics processor. Modern graphics cards like the Nvidia Titan X come with 1-2 GB of memory that is video plus some mighty types like AMD Radeon Pro SSD contain solid-state drives to have a movie memory up to 1000 GB.


The coordination between the operations of these components that are different makes a computer perform tasks for us. Every one of these components has shrunk in size over the years and will continue to shrink more in the future that was coming. The world’s first general purpose computer was a US Army pet project produced under the name Project PX at the University of Pennsylvania. Released on February 15, 1946, it later became renowned as the ENIAC (Electronic Numerical Integrator And Computer). 150 kW electricity was consumed by the 3-0 metric-ton PC. ENIAC went from service.

Modern day computers are more powerful, energy efficient, and compact than their ancestors. But the computers like ENIAC have been the inspiration for all these machines. We’ll carry on to see more development the computer world.
