We can safely say that computer connectorsappeared simultaneously with the computer itself. Even the very first electronic computers, the size of a small factory, had their own connectors. Various peripherals that were relevant at that time were connected to them: card readers, magnetic or even mercury drives, in a word, devices for all sorts of computing needs. The years go by, the computer equipment is constantly being upgraded - the connectors change accordingly, but one thing remains unchanged. They are still an integral part of any computer.
Порты и разъемы компьютера – это набор контактов, which provide the connection of the computer with all kinds of external and internal devices. These include: printers and scanners, drives, cameras, camcorders, drives, monitors, keyboards and more. Perhaps, it will take a long time to list all possible peripherals.
Is there a difference between ports and connectors?Only an experienced professional will be able to draw a clear line between these two concepts, but in everyday practice there is practically no difference. In principle, it will be correct to use both definitions.
All ports and connectors of the computer are divided into external and internal. Although, if you wish, you can offer many types of all kinds of classification.
It is common to refer to external ports thosehanded out outside the body of a computer or laptop. All kinds of devices that are not directly included in it are connected to them: a scanner, printer, telephone, mouse or keyboard. In other words, everything that is connected from the outside.
Internal ports and connectors include thosewhich are hidden inside the system unit or enclosure of the device. These ports are connected built-in devices: drives, hard drives, video cards, sound or network cards and much more.
As already noted, the external port is a connector,through which various devices are connected from the outside. Since there are quite a few such devices — perhaps several million — then the developers came to the logical conclusion that at least some of them need to be standardized. Ports and were originally designed to combine the many ways to connect an external device and a PC.
Ports vary in data rate, format, and other features. We give the most basic of them:
And these are just the main external connectors of the computer. In reality, they are much more. But they are less common.
Non-peripheral ports are connected to the internal ports.and internal devices that go directly into the hardware of each computer. There are also a lot of them, most of them are located on the motherboard:
All these are just the main types of computer connectors.Over the years of their evolution, they have come a long way, some of them have forever "left the stage", others have transformed and improved, as, for example, this happened with SATA or USB ports.
Often, especially in low devicesbuild quality, ports fail. This can be expressed in different ways: incorrect operation of the device being connected, or even failure of work. There are many reasons for damage to the port: the structural part “loosened up,” the contacts were soldered or melted, oxidized, and the corresponding controllers went out of order.
In any case, the question of whetherIs it possible to repair computer connectors? It all depends on the nature of the breakdown and the connector itself. For example, the failure of the connector on the motherboard often can not be "cured". But the external ports can often be repaired (for example, if there was a wiring of contacts). However, it often happens that it is easier and cheaper to replace the entire port entirely, rather than trying to fix it.
However, repair the port yourself orconnector from an ordinary user is unlikely to succeed. If, however, to pull into the workshop, then sooner or later it will end with the final “loosening” of the connector in the socket and, possibly, to the closure.
Естественно, ремонтировать разъемы компьютера it is possible on its own only when there is complete self-reliance. Otherwise, it is better to contact a specialized workshop.
Scientifically speaking, pinout ismarking (designation) of contacts inside any connector. Well, it's easier - the appointment of each of the pins or holes in the connector. For example, one contact may be responsible for powering the device, another for sending data, the third for receiving them, the fourth for grounding, etc.
In schemes, pinout is often denoted either by numerical or alphabetic methods, or in a different color.
Pinout computer sockets helps withrepair of the port, and can be designed to try to connect a device that does not normally connect to a given port, but can be connected through the pinout of the necessary contacts (although the result is not guaranteed).
Of course, neither ports nor connectors are still very long.time will not go away from computer technology. Of course, they will be modified, improved, there will be new standards for the exchange of signals. In short, everything will be even better and faster. Perhaps the transition from physical ports to virtual. You can fantasize on this topic indefinitely.
There is also a trend of gradual withdrawal fromwired ports. Already today, manufacturers at the first opportunity try to introduce wireless ports into their devices. However, computer connectors as such, of course, will continue for more than a dozen years.
