What is Desktop Computer and When Did it Arrive?

What is Desktop Computer Definition

What is this desktop computer? Perhaps we all know because we see it in our homes, in offices, in shops. Computer monitors are considered computers, which is not correct because it is only a screen showing us all the activities going on within it.

The collection of all devices is called a computer. It is a computer that is designed to be in a fixed location. It is either an all in one machine where all the things are on the same desktop, or there is an assembled form of all the devices.

Unlike laptops and other portable devices, it does not have internal batteries, due to which it is always connected to a power source.

In earlier times, when we talked about computers, only desktop computers were available on personal computers. Since laptops and tablets were not available at that time, all home PCs were desktop computers.

Therefore, the term “desktop computer” is still used to separate personal Pcs and large computers such as mainframes and supercomputers.

For the past several years, desktop computers have been a prevalent type of personal computer, but with more laptops, desktop Pcs have been overtaken in sales. And with the increase in mobile computing, this trend is gradually increasing, and in the coming time, it will go even further.

But whatever new technology you bring, these desktop computers have always been a popular choice in many business workstations and based on family computers.

So today, I thought, why should you be given information about what a desktop computer is and how it works to get the answers to the questions arising in your mind. Then, without delay, let’s start and know what a desktop computer is.

What is a desktop computer?

Desktop Computer Definition: This is a personal computer that fits perfectly on top of or under your desk. It has many components such as a monitor, keyboard, mouse, CPU etc.

While the laptop is made more portable, the desktop computer is designed to be stable in one place. It does not have batteries like other portable computers. Instead, they have to be constantly connected with a power source.

If you want to know more about Desktop Computer, you will have to read this article thoroughly.

What was the first desktop, and when did it come?

The first desktop computer was the Hewlett Packard 9100A, introduced in 1968. After that, desktop computers of millions of varieties were released and used all over the world.

These were the earliest computers of the mid-1960s; they used to be very big, which used to cover almost entire rooms. At the same time, those who used to be smaller computers were called minicomputers, and they used to be the size of a desk.

Where is the file created on the desktop?

One file (which is an abstract concept) in a natural computer system also needs a real physical analogue if it exists anywhere.

If we talk about physical terms, most computer files are stored in some storage device. For example, most operating systems store files on the hard disk itself.

What memory does the desktop use?

People often ask these questions, which memory is used on desktop or laptop. Then there is a simple answer – Desktops uses DIMM ( Dual Inline Memory Module ) boards, while laptops use SODIMM ( Small Outline Dual Inline Memory Module ) boards.

The size of SODIMMs is precisely half as compared to the width of DIMMs. They are used to control temperature and power draw, where they can also consider battery life very well.

DIMMS is installed in horizontal DIMM banks; SODIMMs has diagonally slanted banks to create more space.

What is the memory of a desktop computer?

Like I have said earlier, Dual Inline Memory Module boards are used in Desktop Computer based on memory.

Let us know about their different types further. Before that, do not forget to read what is RAM.

Desktop PC Memory (DIMM)

Well, there are many types of RAM types available for desktop computer systems. The most commonly used types used more in recent times are DIMMs (Dual In-Line Memory Module), and these are small circuit boards that hold memory chips. Let us now know about the other types of DIMMs:

SDRAM – Synchronous Dynamic Random Access Memory
SDRAM has a complete form, Synchronous DRAM; it is a type of DRAM that synchronises itself according to the CPU’s bus. SDRAM is the standard memory of modern PCs in recent times.

If we pay more attention to the SDRAM, then the “PC” used in it represents the system’s front-side bus speed. (For example, PC100 SDRAM is designed for equipped with a 100 MHz front-side bus.)

DDR SDRAM – Double Data Rate Synchronous Dynamic Random Access Memory
DDR SDRAM is the complete form of Double Data Rate-Synchronous DRAM, a type of SDRAM that supports data transfers in both edges of the clock cycle (rising and falling edges), effectively double the memory chip’s data throughput.

DDR-SDRAM also consumes less power, which makes it a better option for notebook computers. DDR-SDRAM is also known as SDRAM II. The subsequent versions of DDR-SDRAM are DD2 and DD3.

DDR2 SDRAM – Double Data Rate Two (2) Synchronous Dynamic Random Access Memory
This next step up is the DDR SDRAM. DDR2 SDRAM has many new features and functions that enable higher clock and data rate operations.

DDR2 transfers 64 bits of data twice every clock cycle. DDR2 SDRAM memory is not compatible with current DDR SDRAM memory slots.

DDR3-SDRAM – Double Data Rate Three (3) Synchronous Dynamic Random Access Memory. This is the third generation type of DDR-SDRAM, an upgraded version of DDR2-SDRAM; along it offers reduced power consumption, a doubled pre-fetch buffer, and more.  Bandwidth offers due to increased clock rate.

Note  A RIMM is a type of memory developed by Rambus, Inc. RIMMs are similar to DIMMs, but they have a different pin count.

What is SODIMM? Why is it used in Notebook / Laptop Memory?

SODIMM has a complete form Small Outline DIMM; it is a smaller version of DIMM Modules used in Desktop. SODIMM is mainly used in notebook or laptop computer. Because its size is small and it can be easily fit anywhere.

The main difference between Notebook RAM and Desktop RAM is its form factor: its physical size and its pin configuration. A full-size DIMM consists of 100, 168, 184, or 240 pins and is typically 4.5 to five inches in length.

In contrast, the SO DIMM consists of 72, 100, 144, or 200 pins and is also smaller in size, from about 2.5 to 3 inches. Such SO RIMMs, which are very similar to SO DIMM, but like DIMM / RIMM, are also Rambus, Inc. Uses technology and have different pin counts.

Which desktop is right now Dell or Lenovo (HP)

If you want to buy a desktop computer, you often come across two companies, DELL and Lenovo (HP). Let’s know about both of these Desktops.

About Dell Computers, which you must consider:

– Its desktop cases are very robust.

–  good, reliable, efficient power supplies

– Most of these high-end gaming desktop machines are on offer.

– It has good quality desktops, silent PCs.

– Most computer cases and motherboards are personalised, so they are not compatible with standard ATX and mini ATX points and computer boards.

– Some PCs also use a personalised connector for power supply.

– In some PCs, they use different coolers instead of standard ones, making it impossible to reuse in other computers.

– They have more suitable and reliable laptops.

– Reliable, more good quality display monitors, and also durable.

– It was completely 100% focused on Intel in the past.

About HP Computers, which you must consider:

–  good, reliable desktop cases

– Better power supplies

–  good desktops, and silent PCs

– There are not many offers in them. postoffice is oriented.

– They use ATX mounting standard for their motherboards and computer cases.

– They use standard connectors for their motherboards and use interchangeable coolers for the CPU.

– They have good quality monitors, which have slightly better image quality than Dell, together it is more durable.

– There is better support from AMD.

Inaccessible language, then I should say:

Dell:   They are cheap, slightly slow in their paper specification, and they are more robust. Their laptop is much better than desktop.

HP:  They are more pricey (expensive), faster, have a better battery life which lasts longer. Their desktop is much better than a laptop.

What are the Advantages of Desktop Computers?

Let’s know about the advantages of Desktop Computers.


They are much cheaper than laptops. You can get a better configuration at a lower price, saving a lot of money from the user. They are used in most schools and offices.

Charging and overheating is not the problem.

There is a problem of overheating due to overcharging and overuse in laptops; there is no problem on desktop. You can use them ON for hours.

It can assemble quickly, and its parts are readily available

On Desktop, you can soon make any parts yourself to customise them according to your needs.

But the laptop parts are primarily built-in, so they are not readily available, and their features are also not expensive compared to the computer.

What are Disadvantages of Desktop Computers

Let’s know about the disadvantages of Desktop Computers.


Desktops are static. They are fixed in one place to use. At the same time, you can transfer the laptop from one place to another.

Noisy and Space are required.

They are noisier than laptops because they have more significant components. Together they also consume more space as they are installed in a larger area. For this, they need a separate desktop.

It has less style and also has a lot of cables.

There is no difference in his style in about 10 to 15 years. At the same time, many changes have been seen in the manner of laptops.

Many Cables are used in the Desktop, which reduces its design.


I hope that I have given you complete information about a desktop computer, and I hope you guys have understood the desktop computer definition.
