The technological era is undoubtedly characterized by the standardization of technological devices, these being used by the entire population, being accessible and easy to use by virtually any person.
Thus, we use technology for everything, counting for it, with an infinity of devices. Among all of them we have several types of computers, which are what we will see here today, although, without a doubt, there is still much more.
If we do not stop to think for sure that the answer to the computers that exist is concise, but, nothing is further from reality. Let’s see what this device is and what are the types that exist today, because some, in fact, is no longer used for having launched more modern products that fulfill the same functions.
Learning about these devices you can always choose the one that best suits your needs so that you will not have to settle for what others advise you but you can weigh yourself what you want to have.
Types of computers
Most people who ask them what a computer is and what types they know will answer that the computer they have at home with which they connect to the mail, watch YouTube and the like; This would be the personal computer or PC. At most, we talk about the laptop, fully extended also in society.
However, according to its definition, we have to say that a computer is any device that includes a microprocessor. Therefore, there are too many types of computers than we can imagine, and this is precisely what we want you to know today.
The most powerful computers in the world, those that can process the greatest amounts of information and solve the most complicated operations are supercomputers. In Fact, supercomputers are a set of very powerful computers connected to each other to increase their capacity exponentially.
The world’s most powerful supercomputer is at the National University of Defense Technology in China. It is called Tianhe-2 and has an average yield of 33.48 petaFLOPS. As an informative fact, each petaflop means that the computer is capable of performing more than one billion operations per second.
Desktop personal computer:
It is the tower-shaped equipment, vertical or horizontal, that we have all seen on occasion, the one we have on the desk, the one we see in offices.
It is a large device that includes a set of parts (processor, graphics card, hard disk, RAM, ROM) attached to a motherboard and to which various peripherals, input, output, and hybrids are added, to be able to give and receive information in relation to the computer. We also have the version that comprises a tower and screen in the same device, that is, the computer already includes a panel in which we visualize the content.
Portable personal computer:
It is the mobile version of the previous one and was the 4th revolution of personal computing. It is a smaller device that condenses the power and functionality, for which smaller parts are used and better use is made of the available space.
It works without wires, by the battery, which allows us to move it from one place to another to use it where it comes best. Its name in English comes, in fact, from this characteristic, since they are called laptops, which would be those that go “on the lap”.
The first laptop as such was made by Epson in 1981 and at the time was considered the “fourth revolution of personal computing” by BusinessWeek magazine. After the relief of Windows 95, laptops became popular, and are currently the best selling personal computers.
The term laptop comes from the English lap -regazo- and top -encima-, while they are also called notebooks because of their similarity to notebooks. They have a screen, keyboard, touchpad, processor, hard drives, memories, and battery.
The netbook is a personal computer even smaller than the previous one, 10.1 inches. The concept is the same; A flat and portable device. However, it is also more basic, with only the essentials to do simple computer work. This means that they do not carry dedicated cards or CD players, for example. Obviously, this makes its price also lower.
The tablet is a flat device formed mainly by a touch screen that, in addition to allowing us to see the information, makes it possible for us to give the orders and the computer to receive them without connecting peripherals.
Inside it has very small internal pieces whose base is that of desktop computers but in an even more basic version of what we have already been seeing in the previous types. Thus, it is an element designed for internet browsing and the execution of simple video games; a kind of larger smartphone with similar components and operation.
It appears in a popular way in 2010, being the Apple iPad, although the first tablet to be marketed in the world we saw it much earlier, in 2001, from the hand of Nokia.
PDA or personal digital assistant:
We also call it a PDA or electronic agenda or pocket computer. They are similar to a smartphone in terms of size, shape, and mode of use, with a touch screen and a few buttons (Power, Home, etc). It is a very compact computer, between 4 and 7 inches that work with touch screen and flash memory, many more features. Currently, due to the enormous advance of the smartphone, these are practically not used.
They are those that can be used in different ways depending on the arrangement of their parts. The one that has succeeded the most is the convertible laptop, which is nothing more than a tablet to which a keyboard can be attached so that, in cases in which it is easier for us, we can use it as a laptop and, withdrawing it, we stay Only with the tablet, lighter and more manageable and equally useful in many circumstances. We have the same option for some smartphones although, by size, this option is not much in demand.
An intelligent television is a TV set that has been incorporated with intelligent functions, counting, as it happens with computers, smartphones, and others, with an operating system, a processor, its RAM and even internal storage to be able to download in the telegame and applications as well as to record content they are televising
Wearable or body computer:
They are all those smart devices that have a microprocessor and can be worn, hence the “wearable”.
We talk about smartwatches, Google Glass and this type of device that allow us to receive information and act on it as part of our clothing and complementation.
They are equipment that, as the name implies, include elements that favor rapid work, with a very good processing power, different capacities and huge screens that allow perfect control of several activities at the same time.
Although before they were something much more bombastic, today we see them mainly in workspaces of developers or engineers.
It is a device that consists of an optimized computer that offers its resources and functionalities to other computers using the network (internal or external) to communicate.
Its main feature is the huge internal memory, in addition to a large processing capacity to work with several computers at once.
It is the most basic version of a computer, the minimum component for it to work, designed, in addition, in a very small size but with important computing power.
It includes a chipset with the central processor, with general pins, a very simple graphics processor, a small RAM, various connections such as audio and video output, Ethernet rosette, USB ports, card reader …
In short, it is a computer that fits us in the hand and to which we can attach if we wish, housings, so that it looks more aesthetic but, despite this, it is fully functional without any type of addiction.
Mainframe or central computer:
The mainframe is a device of enormous dimensions with high processing capacity, capable of working with a number of applications counted by millions. In addition to processing data, they are very useful for storing them. They are especially interesting when it comes to controlling different terminals of a virtual nature.
They are considered the most powerful of the moment, processors of unimaginable amounts of information. Although it is known as a supercomputer, it is still a very powerful set of smaller computers, although, due to its configuration and functionality, they work as one, offering a performance that cannot be found on any other computer. We speak of an authentic barbarity, with the capacity to perform billions and billions of operations in every second, something for which we had to define a new concept of measure, the FLOPS.
This device is between the mainframe and the personal computer and is also known as the middle server.
They work simultaneously with several tasks, with really fast processing and allowing the connection of a huge number of users, each with its corresponding equipment.
Minicomputers are a type of device that is in a niche between mainframes and microcomputers . Minicomputers are a third type of computer capable of handling much more input and output data than microcomputers, also called personal computers, although some minicomputers are intended for a single user, they are capable of controlling hundreds of terminals.
The minicomputers represented a more economical solution for companies that need a computer with a greater processing capacity if they lacked capital or did not want to invest in a mainframe. The main manufacturers of these equipments were DELL, IBM and HP.
The name “Minicomputer” tends to be baffling today, but it is a term coined in the 60s, where the word “Mini” did not mean the same as today. A classic example of minicomputers is the AS / 400 series, designed and created by IBM. Over time the minicomputers have been disappearing due mainly to the computing power that other types of computers could offer.
What will the future of computers hold for us and what will be the next step?
In this sector, innovation is not stopped. The future is given by technology and, for this reason, it is necessary to always go a few steps ahead, so that, despite not yet enjoying this type of solutions, it is already known, of course, how to work in A few years, what kind of processing devices will exist, etc.
The two great points that will be touched will be:
Quantum computing We have already seen something of the subject, in fact, in our country, and an exponential improvement of the elements related to artificial intelligence and the achievement of results of digital calculations is promised.
Miniature computers. We have already seen that the plates have a lot of capacity in a very small space but this will go further, seeking to create what is itself a pocket computer.
Computing is changing all the time. In the future of computers, promising scenarios such as quantum computing are opened , machines with incredible processing capabilities that are just beginning to be created, while pocket or miniature computers will seek to make their way among common users.
Technologies such as the Internet of Things, which plans to turn all objects into smart ones, are also based on miniature computers. As time goes by, the types of existing computers will continue to diversify, while others will probably disappear. This is how the future of technology works.
