The USB or Universal Serial Port (in English Universal Serial Bus) is a protocol used to connect peripherals to a computer. Basically, it is a standardized port so that it can be used by several types of hardware elements. Some of the most modern elements used in USB ports are digital cameras, printers, scanners, USB memories, mobile phones, iPods, and other mp3 music players. The first known USB technology began its development in 1994, co-invented by Ajay Bhatt of Intel and the USB-IF organization (USB Implementers Forum Inc.). This organization is formed by the leaders of the information technology industry such as Intel, Microsoft, Apple, and Hewlett-Packard.
Before the USB port existed, computers used serial and parallel ports to connect devices to computers and thus transfer information. Individual ports were used with peripherals such as keyboards, mice and printers. We all remember the rounded ports of various colors where we had to connect the keyboard and the mouse so that it worked correctly on a desktop computer. Parallel ports were capable of transferring data at a rate of approximately 100 kilobytes per second, and where serial ports could have transmission speeds of 155 to 450 kilobits per second. In some cases, the different ports could not work at the same time, with the consequent delay of data transmission.
The high level of incompatibilities and the attempt to use very different interfaces for each of the devices to be connected to the computer created the need for a technology such as USB, which could take most of the existing ports and reduce it. on one only. The immediate interaction of the device with the computer without the need to restart the computer was an added advantage to the efficiency of USB technology. With what, a simple USB port could handle (the solo) 127 different types of different devices, without showing any kind of incompatibility between them.
USB 1.0 was launched in late 1995 and was capable of transferring data at a rate of 12 Megabits per second. And a revision of this standard, USB 1.1, not only transferred information at a rate of 12 Megabits per second but could also operate at a lower speed of 1.5 Megabits per second for devices with lower bandwidth. This made the USB 1.1 version much more efficient and was used much more than its predecessor.
In 1998, the iMac G3 was the first personal computer that discontinued the serial and parallel ports in favor of the USB port. This implementation facilitated the rapid expansion of devices with USB connection, instead of those with traditional ports. The combination of ease of use, its own load capacity and the technical specifications offered by the USB helped this port to win the battle against the classic ports.
With a data transmission speed forty times higher than 480 Megabits, USB 2.0 was launched in 2000 and became the official standard the following year. In addition to its high-speed data transfer, the USB 2.0 port was capable of operating at two lower speeds. At 12 megabits per second (like its predecessor, USB 1.1.) And 1.5 Megabits per second (to be used in peripherals like the mouse that requires much less bandwidth to work). A USB 2.0 port could communicate perfectly with devices with a USB 1.1 connection, however, a USB 1.1 port could not communicate correctly with a device that had a 2.0 connection.
The USB 2.0 connection also offers the functionality of being “plug and play” for most peripherals and storage devices. This new protocol version also offered new features that were not offered in the previous versions. In the year 2000, USB sticks (or Pendrives as they are commonly known) were also launched – a rewritable storage device “Plug and Play” that was initially sold by IBM and Trek Technology. Initially, these memories could store 8Megabytes of data. More than a decade later, the storage capacity of these memories has surpassed 256 Gigabytes in a single pen drive.
These memories allow up to one million re-recording of data, making them practically functional for life. Older models had a connection speed of 12 Megabits per second. While current versions of USB 2.0, with NAND flash memory technology, can almost reach high transmission speeds of 480 Megabits per second, being more than 20 times faster than older models. The latest version of the USB memory, version 3.0, allows data transmission speeds of up to 4.8 Gigabits per second and has full compatibility with devices with USB 2.0 connection and ports with this connection. A USB 3.0 cable or a device with USB 3.0 connection can be connected to ports with 2.0 technology, but the maximum transmission speed will only work with ports 3.0.
Some USB 3.0 models were put on sale for final consumers in 2010, however, the adoption of this latest standard is still in development, since the new peripherals and motherboards have to adapt to this new protocol, and we also have than to renew the current park of computers so that all work under this standard.
USB memories have also become popular in the promotional gift market as it is a highly customizable product, as they can be marked with a company logo or create the shape you want, and at a very attractive price as a promotional USB gift. The price of a personalized USB memory starts from 2.10 euros (including customization) for large orders, at a slightly higher price for smaller orders.
It also depends on the material in which the casing has been made, the metal ones being the most expensive and the plastic ones the cheapest.

More power, more speed, and fewer cables and connections. This could define, in very few words, the advantages of USB4, the new standard of external memory that has already been officially announced, although we will have to wait a while for it to be in the market. In usbpersonalizado.es we want to be aware of all these developments, as in the future we will have custom USB4 models, which will give a great boost to the catalog and a new option for companies to strengthen their marketing and branding strategies. Therefore, today we want to tell you all that the evolved USB4 will bring again with respect to the external memories of the USB 3.2 standard, which have just been announced, and all the advantages that will involve users, which are not few. We are going to know the keys of the USB4, the new generation of external memories. Can you come with us?
One of the clear points of the new UBS4 is the novelty in the denomination itself. While in the previous versions the number came separated, as for example in USB 3.0 or the more updated USB 3.2, the new USB4 simplifies its denomination in a single word. Another new feature is the fact that it can only work with USB type C ports, which is expected to have a necessary transition period in which the current USBs and the new standard 4 coexist, which will mean the more complex change so far experienced in the technological evolutions of USB.
Thanks to the new USB4, it will be possible to charge the laptop and connect several monitors and peripherals using a single cable, which will simplify the tangles of cables that are needed today for these tasks. On the other hand, Intel has also announced that Thunderbolt 3 will be integrated into USB4, a fact that will improve data transfers using several devices together. An integration not common up to now in PCs, although it is in Mac computers (Apple).
According to official statements about the USB4 collected by Gizmodo , this new USB “defines a method to share a single high-speed link with multiple types of final devices in a dynamic way that better serves the transfer of data by type and application”, with that you can see “multiple external displays and other devices such as hard drives connected through a cable or a cable chain instead of a hub,” they explain.
