Definition of Port
1. Meaning of PortA port is an artificial construct built by man on the banks of a stream with the main objective of organizing the transport and trade of other land regions. The port can be found both at the lake and the ocean, a river, a lake or a pond. It is also the space that connects two points since land is the last place of the human habitat in the presence of aquatic environments.
Most ports meet economic functions, mainly trade and fishing. In them, the man set constructions of varying dimension so to adapt to water conditions and enable the development of all kinds of tasks related to these activities. Some ports worldwide are enclaves of power since they receive and send infinite amount of manufactured goods, and material assets and acquisitions.
Yet there are ports that can be built almost exclusively for tourism and recreation. This happens especially in regions where tourism plays an important role, perhaps becoming the main economic activity of the community in question. Clear examples of this are the ports built on the islands and coasts of the Mediterranean where there are almost no trade or fishing, but will serve as a temporary parking place for boats, yachts and cruisers.
For a port exists and is carry out their main activities properly, you must have certain essentials for them. First, the building and construction should gain some sea space provided to allow control of the waters (channeling dams, canals, docks, harbors and locks). On the other hand, it must be organized properly the land where they settle reception activities, monitoring and reorganization of production that arrives or departs. Finally, a port is central to have a proper transport system through which the goods to be imported or exported can be mobilized quickly and effectively.
2. Definition of PortThe word comes from the Latin Portus harbor, and is defined as the place where the boats can perform loading and unloading operations, both of people and any type of commercial cargo. The ports are located on the banks of rivers or on the coast, and are so placed as to allow the boats easy access to both land and water, and protection and shelter in case of turbulent water or storm.
The ports have been instrumental for trade for centuries. For many years, the boats were the only option for moving people and cargo across continents and large seas. Even today, shipping remains an option widely used for carrying cargo, although not as popular with the people.
currently exist worldwide from small ports, capable of receiving goods to small villages or nations, to extensive and modern ports, equipped with advanced technology and various cargo storage kilometers. The most innovative feature cranes, forklifts, quick access to trains and highways, channels and facilities for maintenance of some boats. Additionally, some ports are so good that can be converted into real economic engines for entire cities.
ports exist designed for each specific type of boat. To trade in fish, for example, ports are specifically designed for this purpose, while for the cruise, there are so-called cruise ports, with facilities for the passengers and the boat filled with all kinds of supplies, from fresh water and fuel to food and every comfort. The latter are usually reserved for tourism and vacation use entirely, and for the same reason are often located only in cities with high tourist season.
3. Concept of PortWhen you mention the concept of port is looking to reference the site located on the coast or on the banks of a river where boats conduct boarding and disembarkation and loading and unloading. This is possible by natural or artificial features of the area in question.
The term, which finds its origin in the Latin Portus, usually mentions to infrastructure and the services that are provided in a space of calm water to stay safe craft while performing these operations.
Ports can provide services for business (those who load and unload goods for transportation to other regions), the fishing industry, national defense and tourism.
In the sea area, the Ports include works (such as dams or locks) for the purpose of protecting the surf boats, signaling (buoys, beacons, lights, etc.) and docks for the maintenance and operations. In land area, moreover, springs are installed to facilitate berthing and mooring of vessels and tanks to collect the goods.
A mountain pass, finally, is a step that allows crossing a mountain. They usually have steep and winding routes, usually covered with snow.
should be noted, moreover, that the computer is known as a port to an interface that provides the ability to send and receive various kinds of data, which can be physical (hardware level, with inputs for connecting the monitor, printer and other peripherals) or logical (managed by the software). USB, PCI and Serial ports are some of the most common physical.
history USB port
USB Meaning of Acronym in Castilian is "universal serial bus", and emerged in 1995 from the merger of several companies seeking create an interface that would connect multiple types of devices using a standardized connector, and serve for different systems, PC or Mac out, companies are DEC, IBM, Compaq, Microsoft, Intel and Northern Telecom.
This type of connection, which presented to the market in 1996, successfully achieved its purposes, among which were improved transfer speed, offering 12Mbps (Mega bits per second) and reduce the size of cables and connectors. Moreover, from the beginning it was possible to connect up to 127 devices per port, the advantages of implementing Plug and Play and Hot Plug, which results in the use of a peripheral instantaneous once plugged, opposed the need to restart the computer.
Four years later, another group of companies showed the world a new USB version, called 2.0, which significantly increased performance, reaching speeds of 480Mbps. This review is completely backwards compatible, so it is possible to use a 1.0 or 1.1 device into one of these ports, cables and connectors have the same appearance and size.
With computer market demands, it was necessary to improve USB technology offer more transfer speed and other advantages. So, in 2008 was born the revision 3.0, with a better use of energy, a top speed of 5Gbps and backward compatibility with 2.0 connectors.
Interestingly, the maximum speed of USB 2.0 is 40 times that of its predecessor, while in the next generation increased only slightly more than 10 times. This does not speak of a lack of resources to produce faster devices, it is adapted to the demands of the market, that slowly reach the expected performance from their equipment. In the same way, as will agree to all Internet connections 100 Mbps, 1000 ansiemos unlikely or 10,000, since there is no way to use them.
