What is a laptop for a modern person? This is such a thing that is simply indispensable. It is he who helps to fulfill a lot of tasks very quickly, replacing a whole host of other devices. But few know about such an important thing all that is required. So, consider what a laptop is (a definition will be given below), what are its functions, capabilities and internal structure. So, let's begin!
What is a laptop: definition
The etymology of the word is easy to establish. What is a laptop is easy to understand. Everything is clear if you know English. Translated into Russian, this word means "notepad." Usually, a person in his organizer writes down a lot of what is needed, draws and uses for his business needs. The most important thing is that he is always with him, and at any moment you can look into him and find out something that has already been forgotten. So, the laptop has similar parameters. It is intended for the business needs of the owner. And most importantly - its portability and independence. No need to constantly sit near a power source. A portable and independent personal computer - this is the answer to the question of what a laptop is.
Laptop features
A laptop, like all devices, must perform certain tasks. In essence, this is the same personal computer, more compact and non-volatile (at least for several hours). Even all components and the internal device are the same as those of a PC.
On it you can deal with the processing and creation of documents. Fortunately, the standard Microsoft package helps. Also, the laptop makes it possible to quickly enter the World Wide Web. You can connect a cable to it directly 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 access the Internet anywhere.
Differences between laptops and PCs
What is a laptop and how does it differ from a regular computer? The first is a small copy of the second, which has slightly different features. Well, let's get right to the differences.
Immediately you can highlight the feature by which these two devices are different - overall. The fact that a laptop is much smaller than a desktop computer is immediately apparent. This is one of the main advantages of one over the other. Thanks to its small size, you can work on a laptop even on the road, transport it to another city or carry it with you constantly so that it is at hand. Of course, it’s problematic to transfer a PC to another room together with its wires, monitor, various devices and the system unit itself. Therefore, laptops have no equal in the mobility category.
Another nice plus - no need to connect additional attachments. Everything is built-in in the laptop: both the screen, and the keyboard, and even the mouse (touchpad). Without all this, a regular desktop computer will not just be useless, but even a burden. This category also includes autonomous work in remote places without access to an electric network and quick connection to the Internet via wireless networks. Therefore, another plus sign goes to the piggy bank of miniature computers.
Cons of laptops
But, despite all these advantages, these devices also have disadvantages. A significant disadvantage of all laptops is their low power. In this case, they are simply not comparable with conventional desktop computers. Even if the laptop is gaming (which means that it has the highest possible settings), then it pulls in power only to an average PC. But this is also a moot point, for those who just need to work with documents, a powerful laptop is simply not needed.
Replacing a specific element in the device will not be so easy. In comparison with computers, where everything is simple and clear, in laptops (especially in cheap models) it is sometimes impossible to replace some broken element. Therefore, you need to use such devices extremely carefully.
What is hibernation in a laptop?
Each device has its own interesting features. A regular user will ask: what is hibernation in a laptop? Yes, the word is interesting. The function itself is not very popular. Few people know about her. Added to this is the fact 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 register a certain code through the command period. By the way, in exactly 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. But here are the differences: sleep mode involves the device operating at reduced power consumption. In this condition, the battery can last up to twelve hours. In hibernation mode, the device can save a charge for a longer period. How does he work? Everything is very simple: the system creates an image of RAM and saves it on drive C (therefore, you need to have enough space on it). Then the power consumption simply stops. You can even pull the plug out of the outlet. When a laptop is suddenly needed, you can get it out of this state.
The plus is that, in contrast to the usual download, which lasts about one minute, you can work after ten seconds, and the effect will be as if the laptop was not turned off (everything will be saved). There is no energy consumption while in hibernation mode. The function itself is not really needed for ordinary PC users. It may be useful only for programmers or very busy people, but there are very few of them. It’s not 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. It’s even more convenient for some to use the touchpad rather than the mouse. In places where there is not so much space (in a car, minibus, small cafe), it is easiest to use it. Now it’s clear what a touchpad is in a laptop.
Chipset
What is a bridge in a laptop? Typically, 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 contacted a service center with a breakdown. They may say that the north or south bridge has burned down: you will have to change the motherboard. Such words perplex the average user, because he does not know what the north bridge is in a laptop and why it is needed.
Indeed, why is it needed? First you need to find out what a chipset is in a laptop. Such a strange word is called the north and south bridges together. Together they are responsible for the operation of the components of the motherboard. The north bridge has many tasks. That is why it is so important. Its replacement is not possible because it is built into the motherboard. This node is responsible for the compatibility and operation of the so-called RAM memory (RAM), processor and video adapter. He also performs other tasks. Due to the fact that they hung a lot of tasks on such a chip (and not the easiest ones), it overheats very much. For him, even a miniature cooler is sometimes installed, but most often a simple passive radiator. Its temperature is thirty degrees more than that of the south bridge or other node of the motherboard. Excessive overheating or overload will simply kill him, so the north bridge breaks so often at the laptop.
South bridge
The south bridge is the smaller brother of the north. It also crashes quite often. That's because for this node is not supposed additional cooling, unlike the north. As a rule, the south bridge "takes a hit" and does not allow the entire laptop to die. A common cause of failure of this particular node is overheating or short circuiting of the USB connector: it simply burns out.
