What is a laptop and what are its functions?

What is a laptop for a modern person? This is such a thing, without which you can not do without. It helps to accomplish a lot of tasks very quickly, replacing a whole lot of other devices. But few know all that is required about such an important thing. So, let's consider what a laptop is (the definition will be given just below), what are its functions, capabilities and internal device. So, let's begin!

What is a laptop: definition

The etymology of this word is easy to establish. What is a laptop, it's easy to understand. Everything is clear if you know English. In Russian, this word means "notebook". Usually a person in his organizer records a lot of what he needs, draws and uses for his business needs. The most important thing is that he is always with him, and at any time you can look into it and learn something that has already been forgotten. So, the laptop has similar parameters. It is designed for the business needs of the owner. And most importantly - its portability and independence. Do not constantly sit near a power source. A portable and independent personal computer - this is exactly what is the answer to the question of what a laptop is.

Laptop Features

A laptop, like all devices, must perform certain tasks. In essence, it is the same personal computer, more compact and non-volatile (at least for several hours). Even all components and internal devices are the same as those of a PC.

You can process and create documents on it. The blessing in it helps the standard installed Microsoft package. Also, the laptop allows fast access to the World Wide Web. You can connect the cable directly to it or use special wi-fi routers. Very convenient: you sit in a cafe with a cup of hot coffee and work. That's what a laptop is - it's always a quick way to process data and enter the Internet anywhere.

Differences between laptops and PCs

What is a laptop and how does it differ from a conventional computer? The first is a small copy of the second one, which has a few other features. Well, we proceed immediately to the differences.

At once it is possible to allocate a feature on which these two devices differ - a dimension. The fact that the laptop is much smaller than a desktop computer can be seen right away. This is one of the main advantages of one in front of the other. Due to its small size, it is possible to work behind the laptop even on the road, transport it to another city or carry it with you at all times, so that it is at hand. It's clear, the PC even in the other room is problematic, along with its wires, monitor, various devices and the system unit itself. Therefore, there is no equal in the mobility category.

Another nice plus - no need to connect additional attachments. In the laptop it's all built-in: the screen, the keyboard, and even the mouse (touchpad). Without all this, a typical desktop computer will not just be useless, but even a burden. This category also includes autonomous work in remote locations without access to the power grid and fast Internet connection via wireless networks. Therefore, one more plus goes to the piggy bank of miniature computers.

Laptop cons

But, in spite of all these advantages, there are also disadvantages of these devices. A significant disadvantage of all notebooks is a small capacity. In this case, they are simply incomparable with conventional desktop computers. Even if the gaming laptop (which means that it has the highest possible parameters), then it draws on power only on the average PC. But this is also a controversial issue, for those who just want to work with documents, a powerful laptop just is not needed.

To replace a certain element in the device will not be so easy. Compared with computers, where everything is simple and clear, in laptops (especially in low-cost models) it sometimes happens impossible to replace some broken element. Therefore, to use these devices should be extremely accurate.

What is hibernation in a laptop?

Each device has its own interesting features. The average user will ask: what is hibernation in a laptop? Yes, the word is interesting. The function itself is not very popular. About it very few people know. Added to this is that not all laptops have it. That is, the function exists, but in order for it to appear in the "Start" menu, you need to write a certain code through the command term. By the way, in the same way you can remove this function from the menu.

Some confuse hibernation and sleep patterns. Yes, actually they are similar to each other and serve for the same. Only here are the differences: the sleep mode assumes the device operates at a reduced power consumption. In this condition, the battery can work up to twelve hours. In the mode of hibernation, the device can save the charge for a longer period. How does he work? It's very simple: the system creates an image of RAM and stores it on the C drive (so you need to have enough space on it). Then, the electricity consumption simply stops. You can even pull out the plug from the outlet. When you suddenly need a laptop, you can take it out of this state.

The plus is that, unlike the usual load, which lasts about one minute, you can work after ten seconds, and the effect will be as if the laptop were not turned off (everything will be preserved). Consumption of energy during the stay in the regime of hibernation is no. The function itself is not very necessary for ordinary PC users. It can be useful only for programmers or very busy people, but there are very few of them. After all, do not be too lazy to spend just one minute to download and one more to open other files.

Touchpad, or touchpad

What is a touchpad in a laptop? This is one of the surprises in such computers. Thanks to him, the laptop does not require an additional mouse connection. You can use the touch panel, as in the phone. Some people even prefer to use a touchpad, not a mouse. In places where there is not so much space (in the car, minibus, small cafe), it's easiest to use them. Now it's clear what a touchpad is in a laptop.

Chipset

What is a bridge in a laptop? Usually ordinary users do not even think about the existence of any bridges in their device. However, such a term can be heard by those people who dealt with a breakdown in the service center. They can say that the north or south bridge was burnt: it will have to change the motherboard. Such words puzzle the average user, because he does not know what the north bridge in the laptop is and why he needs it.

And really, why is it needed? First you need to find out what a chipset is in a laptop. Such a strange word is called together the north and south bridges. Together they are responsible for the operation of the components of the motherboard. The north bridge has many tasks. That's why it's so important. Its replacement is not possible, because it is embedded in the motherboard. This node is responsible for the compatibility and operation of the so-called PAM memory (operational), processor and video adapter. He also performs other tasks. Due to the fact that a lot of tasks were hung on such a chip (and not the easiest ones), it overheats very much. For him, even sometimes install a miniature cooler, but most often a simple passive radiator. Its temperature is thirty degrees higher than that of the south bridge or other node of the motherboard. Excessive overheating or overloading will simply kill him, so the north bridge and breaks so often at the laptop.

South Bridge

The south bridge is the smaller brother of the north. It also fails quite often. All because for the given knot additional cooling is not supposed, unlike northern. As a rule, the south bridge "takes the blow" and does not let the entire laptop die. A frequent reason for the failure of this particular node is the overheating or short-circuit of the USB connector: it just burns out.
