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, then you will have to read this article completely.

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 the space of almost entire rooms. At the same time, those who used to be smaller computers were called minicomputers, and they used to be of the size of a desk.

Where is the file created on the desktop?

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

If we talk about physical terms then most computer files are stored in some kind of 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 in 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 exactly half as compared to the width of DIMMs. They are used so that they can control temperature and power draw, where they can also consider battery life very well.

Where DIMMS is installed in horizontal DIMM banks, SODIMMS has diagonally slanted banks so that it can create more space.

What is the memory of desktop computer?

Like I have said earlier that Dual Inline Memory Module boards are used in Desktop Computer on the basis of memory.

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

Desktop PC Memory (DIMM)

By the way, many types of RAM types are available for desktop computer systems. The most commonly used types that are used more in recent times are DIMMs (Dual In-Line Memory Module) and these 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 full form Synchronous DRAM, it is a type of DRAM that synchronizes itself according to CPU’s bus. SDRAM is the standard memory of modern PCs in recent times.

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

DDR SDRAM – Double Data Rate Synchronous Dynamic Random Access Memory

DDR SDRAM is the full form of Double Data Rate-Synchronous DRAM, a type of SDRAM that supports data transfers, in both sides of the clock cycle (in rising and falling edges), so that it can effectively double the memory chip’s data throughput. Can do.

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 of 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.

DDR3SDRAM – Double Data Rate Three (3) Synchronous Dynamic Random Access Memory. It is the third generation type of DDR-SDRAM which is an upgraded version of DDR2-SDRAM, along with it offers reduced power consumption, a doubled pre-fetch buffer, and also offers more bandwidth of increased clock rate. cause.

Note:- A RIMM is a type of memory that is 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 full form Small Outline DIMM, it is a smaller version of DIMM Modules that are used in Desktop. SODIMM is mostly 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 in its form factor; Which is 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 also like DIMM / RIMM, are also Rambus, Inc. Uses technology and also has different pin count.

Which desktop is right now Dell or Lenovo (HP)

If you want to buy a desktop computer, then 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 in offer.

– It has good quality desktops, silent PCs.

– Most computer cases and motherboards are personalized, so they are not very compatible with normal ATX and mini ATX cases and computer boards.

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

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

– They have more good 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. Most Office is orinted.

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

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

In easy 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 better battery life which lasts longer. Their desktop is better is compared to 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 better configuration at a lower price, which saves a lot of money from the user. They are mostly used in schools and offices.

Charging and overheating are not the problem

Where there is a problem of overheating due to over charging and overuse in laptops, there is no problem in desktop. You can use them by ON for hours.

Can assemble easily and its parts are easily available

In Desktop, you can easily assemble any parts yourself, so you can customize it according to your needs.

But the parts of the laptop are mostly built in, so they are not easily available and their parts are also not expensive in comparison to the laptop.

What are Disadvantages of Desktop Computers

Let’s know about the disadvantages of Desktop Computers.


Desktops are absolutely 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 more noisy than laptops because they have larger components. Together they also consume more space as they are installed in a larger space. 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 style of laptops.

Many Cables are used in Desktop which reduces its design.
