A port offers infrastructure for the development of embarkation and disembarkation and loading and unloading operations.
A port is a place located on the coast or on the bank of a river where ships carry out embarkation and disembarkation and loading and unloading operations . This is possible thanks to the natural or artificial features of the area in question.
The term, which finds its origin in the Latin portus , usually refers to the infrastructure and services provided in a space of calm water for the safe stay of vessels while the aforementioned operations are carried out.
Port Features
Ports can provide services for commercial activity (those that load and unload merchandise for transport to other regions), the fishing industry, national defense and tourism .
In the maritime zone, ports include works (such as docks or locks ) with the purpose of protecting ships from waves, signaling (buoys, beacons, lighthouses, etc.) and docks for stay and operations. In the land area, on the other hand, docks are installed to facilitate the docking and mooring of vessels and warehouses to store goods .
A mountain pass , on the other hand, is a pass that allows you to cross a mountain system. They usually have winding paths and steep slopes, usually covered in snow .
In computing, a port is an interface that allows data to be sent and received.
The concept in computing
It should be noted, on the other hand, that in computing , an interface that offers the possibility of sending and receiving various kinds of data is known as a port, which can be physical (at the hardware level, with inputs for connecting the monitor, the printer and other peripherals) or logic (managed by the software ). USB , PCI and Serial are some of the most common physical ports.
The meaning of the acronym USB in Spanish is universal serial bus. It emerged in 1995 from the union of several companies that sought to create an interface that would allow various types of devices to be connected using a standardized connector , and that would serve different systems, whether PC or Mac ; The companies are DEC , IBM , Compaq , Microsoft , Intel and Northern Telecom .
This type of connection , which was presented to the market in 1996 , successfully achieved its purposes, among which were improving the transfer speed, offering 12Mbps (Mega bits per second) and reducing the size of cables and connectors. Furthermore, from the beginning it was possible to connect up to 127 devices per port, implementing the advantages of plug and play and hot plug , which translates into the instant use of a peripheral once plugged in, as opposed to the need to restart the computer.
USB port improvements
Four years later, another group of companies showed the world a new version of USB, called 2.0 , which considerably increased performance, reaching speeds of 480Mbps. This revision is absolutely backward compatible, meaning it is possible to use a 1.0 or 1.1 device in one of these ports; The cables and connectors have the same appearance and size.
With the demands of the computing market, it was necessary to continue improving USB technology to offer higher transfer speeds , as well as other advantages. For this reason, in 2008 revision 3.0 was born, with better energy use, a maximum speed of 5Gbps and backward compatibility with 2.0 connectors.
It is interesting to note that the maximum speed of USB 2.0 is 40 times greater than that of its predecessor, while in the following generation it increased only a little more than 10 times . This does not speak of a lack of resources to make faster devices; It is about adapting to the demands of the market , which little by little reach the expected performance of their devices. Likewise, as we all access 100Mbps Internet connections, we probably won't crave 1000 or 10,000, as there will be no way to take advantage of them.
