Computer Acronyms and Abbreviations

Over time, the technology accumulated within the cabinet of a computer has advanced and modified its function in such a way that it is difficult enough to keep up with it, and even less so with the different acronyms and abbreviations with which all these types are called different hardware.

A clear example of this are the different types of processor and the number of cores that they integrate, the different types of RAM memories, the various data storage systems and others, and it is very clear that if we are not able to recognize the components of a computer , at least in a basic way, we will miss most of the advantages that these devices have to give us.

With how many GHz is one GB? They have nothing to do with each other? If we are not able to solve this, we will have a difficult time choosing our new computer, notebook or printer, since for this we need to master a very strange art: reading computer acronyms or abbreviations.

Created from technical data, technologies and releases of each season. Sometimes we get dizzy with acronyms such as GHz, HDMI, MB, PS2 and others, which help us determine the quality or functionality of each device.

All the technical terms of computing that we must know

In this sense, the world of computers moves around a wide range of acronyms , and if we do not know what they mean, many times we will be lost. If you want to know the meaning of the main acronyms of computing , we invite you to continue reading the rest of the article.

But first, we invite you to learn more about computing in this post: What is computing?

Differences between CPU, GPU and APU

Basically, each of these abbreviations,  APU, CPU and GPU corresponds to a specific type of data processing unit , that is, a processor, however, each of them offers advantages and disadvantages, and is used in different types of implementations. .

APU (Accelerated Processing Unit)

The first of them, the  APU (Accelerated Processing Unit)  is a type of processor that inside houses both the processing unit, the CPU, and the video processing unit, GPU.

This type of implementation offers a considerable advantage in processing speed, which is due to the fact that also in the same capsule it contains a memory controller and a high-speed processing bus,  all of which gives it a high processing capacity of data in a reduced size, becoming more efficient and allowing smaller computers.

acronyms-of-computers- (3)

However, this union and miniaturization comes at a price:  an APU will never meet the demands of a user with heavy graphics, video, or computational demands.  The APUs have been designed for the average user, one who does not require too many demands on their hardware, but who also enjoys some set of discrete requirements.

Without a doubt, one of the most important characteristics of an APU is its consumption, which makes it ideal for mobile devices or implementations for HTPC, for example.
Some examples of APUs are AMD Fusion or Intel with Sandy Bridge or Ivy Bridge, despite not being marketed under this nomenclature.

GPU (Graphics Processing Unit)

The Graphic Processing Units, better known as GPUs,  are the processors mounted on the video cards, and basically they are in charge of showing us the images on the screen, solving millions of calculation operations per second.

The GPUs can be found in our computer in two different ways,  the GPUs in the video cards or soldered directly on the motherboard of the PC, an  implementation that is called  “OnBoard”  or  “Integrated Video” video.

acronyms-of-computers- (4)

GPUs have been specifically designed to perform millions of mathematical operations per second efficiently and quickly,  two fundamental points in video processing , since it is real time.

GPUs also  have the multicore capacity,  necessary and natural reasoning to be able to solve the incredible amount of data that has to be manipulated, and  the number of cores varies according to the manufacturer and the type of GPU in question.  The biggest GPU manufacturers today are AMD and Nvidia.

CPU (Central Processing Unit)

The CPU, also known as the  “Central Processing Unit”,  is in charge of processing absolutely all the operations of the computer, from power on to loading the operating system, and all the functions or operations that it or its user programs perform. Simply put, a computer without a CPU is useless.

acronyms-of-computers- (5)

In general,  CPUs or processors are purchased taking into account the use that will be given to the computer on which it will be mounted.  This means that if we want a computer only to surf the Internet or make Word documents, it  is a crazy idea to acquire a high-end processor with 8 cores and a speed of almost 5 Ghz,  mainly due to the cost and electrical consumption of the same. in addition to the electronics associated with the implementation, such as a power source adequate to the energy requirements of the CPU.

With respect to CPUs and APUs, the fundamental difference is in the use that will be given to the equipment that contains them. If we will use it for basic tasks or a little more, it would be appropriate, in certain scenarios that only the user knows how to determine, an APU, due to its lower energy consumption and size.

acronyms-of-computers- (6)

Now, if the usage requirements are higher, the best then in a computer with a traditional CPU,  and if we want even more performance, a combination of CPU and dedicated GPU,  that is, the well-known video cards, leaving aside the capacity of “Onboard” video  .

Understand computer abbreviations

As we mentioned above, finding a PC or notebook that adapts to all our needs is not exactly an easy task, even more so if we do not know the various terminologies and abbreviations that are used in the field.

That is why from this point on we will find all the technical terms, abbreviations and essential acronyms related to computers to know exactly what we are buying, which will ensure a good purchase for many years, since most of the time manufacturers and sellers tend to mislead us with these acronyms so that they seem more than they really are.
