A computer is, first of all, a computer. Therefore, the integration of these devices into many devices currently no longer surprises anyone. However, what everyone used to call the word "computer", in fact, has the full name "personal computer". And recently even a "personal laptop computer" is gaining popularity. This means "portable", which determines the mobility of the device.
Mobility as the goal of portability
PC can be portable and desktop. A desktop PC is a computer in a complete assembly, which is an interconnected equipment that gives power and versatility, but which is tied to one place because of its bulkiness. Of course, now they are trying to produce as little details as possible, thin displays and mobile wireless mice, but all this is still inferior in convenience to portable PCs. A laptop computer is a much smaller size and a more capacious battery (after all, desktop computers, in turn, always work from the network and do not need long battery life). However, this affects the performance of such devices, which is becoming smaller. However, the computing capabilities of some portable devices are also very large.
Three main categories of laptops
The three main categories in which a laptop is presented are :
- laptop;
- laptop;
- subnotebook.
It is in this classification that they are presented on the market. However, ordinary people tend to confuse this terminology, based on the fact that they are not well versed in this area. Professionals are sometimes confused, since the boundaries of determining certain devices in a particular group are very unclear. Frames are usually set by the size and weight of the device, and each of the categories has its own standards.
Laptop
The very first laptop computer is a laptop. It is a portable computing system in its most pristine, so to speak, form.
A laptop is a very small device. If we consider the term in detail, that "power line" translates as "knees", which means the device should be placed on this part of the human body.
The concepts of "laptop" and "laptop" closely overlap with each other - for example, the Google translator stubbornly perceives them as synonyms, although this is not entirely true.
The main features of laptops
The characteristics of a laptop include the following:
- the screen size should be at least fourteen, but no more than seventeen inches;
- integrated video cards provide high-quality graphics;
- large, comfortable and extended keyboard;
- there is always an optical drive (in other words, a drive);
- the battery capacity allows you to work independently from it for three or more hours;
- easily replaceable components (in case of breakage).
All this leads to the fact that a good laptop becomes a full replacement for the desktop PC. He is a laptop computer, it is not in doubt, but he can compete in performance with non-portable devices.
Laptop
Notebook - from the English words "laptop" ("note") and "beech" ("book"). It is a portable device with a high level of mobility. It is thinner and more minimalistic than a laptop, but because of its mobility it often costs the same or even more expensive.
Among the characteristics of the laptop:
- long battery life;
- simple graphics;
- multifunctionality;
- diagonal of the screen within twelve to fourteen inches.
This is a classic separation of laptops and laptops, which is currently undergoing changes. More often, the terms “laptop” and “netbook” can be found. To describe this classification, a distinguishing feature of a laptop is its combined components, and screen sizes range from fourteen to seventeen inches (like laptops).
Netbooks
A netbook is a “beech” (“book”) for using the Internet (“no”). Usually a small laptop with
a monitor diagonal not exceeding thirteen inches is a netbook. Its performance is less, but battery life reaches more hours. Resource-intensive programs will not work fully on a netbook, difficulties will arise when working with large-scale tables and images. Drives are not built into such devices, and memory (both operational and hard disk) is much less important than laptops.
But netbooks are equipped with high-quality network adapters, and their mobility is very high: they weigh no more than 1 kg and fit in an ordinary women's handbag, because they can be very small - with a screen diagonal of 7 inches.
A synonym for a netbook is precisely the last category - a subnotebook, which is characterized by ultraportability. It is easy to see how smooth but contradictory transitions from one category to another reflect the fuzziness of these terms.
Are these all portable computers?
The species described above do not reflect the entire situation in the modern market. The topic of tablet computers and smartphones, as well as PDAs that have lost their prevalence, is not affected. Further we will focus on them.
Tablets
A portable tablet computer is simply called a tablet. In appearance, a distinctive feature is the lack of a keyboard as
an input device and the replacement of the main functional interface with a full-sized touch screen.
Tablets lose even more performance than netbooks, but their battery life increases. It is easy to notice this proportional dependence.
Tablets usually have sufficient multimedia capabilities and Internet access - the computing potential of the device is aimed at this.
The concept of a tablet laptop is also known, to which a keyboard is still attached to help the touchscreen.
PDA
A handheld laptop was much more popular when smartphones had not yet flooded the market. It was a very small computing device the size of a cell. PDAs are tightly attached to their OS and in the early years of release were intended for use as organizers by business people. At this time, smartphones have the same or even greater functionality, so the PDA has lost its prevalence.
Smartphones
Types of laptops have long included smartphones. After all, they are both PDAs and ordinary mobile phones. Powerful smartphones have multifunctionality comparable to a weak netbook + give the opportunity for cellular communication. For the most part, these devices come with a touch screen, although there are also button models.
Note: when talking about the portability of computing devices, you need to mention portable programs for the computer, that is, those that do not require installation. They are extremely popular for use just on netbooks, which have a lot of memory and computing power.
