USB Full Form & answers to following questions related to USB, hope you will get your answer.
- What is USB full form?
- What is USB?
- Where do we use USB?
- What is the Advantage to use USB?
you must have used a USB cable or USB drive often but do you know how many types of USB? How many versions of USB are?
If you think that if you use Pen Drive that is the only USB then you might be wrong.
What is USB Full Form and Definition of USB?
USB full form is “Universal Serial Bus” .
What is USB means: It is a device or cable that can help you connect your separate parts to your computer. The USB word is connected to the computer world.
Digital Camera, Printer, Scanner, Flash Drive, Mobile Phone, mp3 Player etc. all have a different USB port. USB is a standard that is followed by all the companies. USB basic work is to communicate between two devices.
These USB connectors were developed so that computers and other devices could be easily connected. Various connectors used before the introduction of the USB interface. But after the arrival of it, the whole point of view has changed. There are many benefits of these USB Cables.
In 1994, a group of seven companies (Microsoft, IBM, Intel, Compaq, DEC, Nortel and NEC) started making USB. A team of Intel which included Ajay Bhatt, created the first standard USB in 1995.
USB Versions & Speed
USB 1.0 – It was released in 1996. Its data transfer speed was 12 megabytes per second (MBPS).
USB 2.0 – It was released in 2000. The maximum speed of its data transfer is 480 megabytes per second (mbps). It is also known as Hi-Speed.
USB 3.0 – The version (USB 3.0) was released in 2008. Its data transfer speed is 5 GB byte per second (GBPS). It is also known as Super Speed.
USB 3.1 – It was released in 2013. The maximum speed of data transfer is 10 Gigabyte per second (gbps). It is also known as Super Speed +.
USB 3.2 – This version was released in 2017. Its data transfer speed is 20 GB per second (gbps). It is also known as Super Speed +
Types of USB
By the way, there are many types of USB but in the meantime, we are going to tell some of the most common types.
Type A: This is in the shape of a Rectangle, it has four pins. This type is used most. e.g. – pen drive, mouse, keyboard, data cable
Type B: There are also four pins in it and they are suppressed from both sides. e.g. – Printer, Scanner
Mini-A & Mini-B: This type has five pins. You can see their size in the lower picture. e.g. – Digital Camera, Hub
Micro-A & Micro-B: In Type also has five pins. These types are found in smartphones.
What are the Advantages of USB?
Ease of using: USB has been developed because it can be used easily by users.
Single Interface for Multiple Devices: Due to the versatile nature of USB, it removes complexity in connecting with different devices. It easily connects with other peripherals.
Auto-configuration: There is a need to install the USB device driver only once on the operating system of the host device. Later whenever the peripheral device is connected to the system, it will automatically load its driver, so that it will configure the plugged in device. It can be easily used by it.
Easy to expand: There are 3 to 4 USB ports in general computers (Motherboards) generally. And if more USB ports are needed in the future, then using the USB hubs, we can add external ports.
Having Compact Size: The size of the USB sockets is very small if we compare it to RS232 and parallel ports.
External power is not required: External power is not required to run USB devices because they are made according to which they can provide 5V DC to the host device.
Speed: USB has much more speed and efficiency than other Cables. They provide a speed of data transmission rate of approximately 1.5Mbit / s to 5Gbit / s.
Reliability: These USB protocols can catch large data during data transfer so that they notify the transmitter to retransmit the data. Generally, to ensure the generic USB driver and specific driver software error-free data communication.
Low cost: Due to its versatile nature and high demand, it can be manufactured very cheaply. Due to its high availability of components, its manufacturing can be easily scaled.
Low power consumption: USB devices usually work only in +5V and many works consume current, which are in some Milliampere.
There are also some disadvantages, so let’s know about the same.
What are the disadvantages of USB:
Speed: With the new technology USB 3.0, the data transfer rate of up to 5Gbits / sec can be reached. But this is still very low from Gigabit Ethernet.
Peer to Peer Communication: According to the USB standard, only the host and peripheral interaction can be done. Here two hosts cannot communicate directly with each other. And it also happens with the peripheral. But only supports peripheral communication from interfaces such as FireWire peripheral.
No distance: Connecting cable according to the USB standards can be up to a maximum of 5 meters, after which USB hubs are used to extend connectivity.
Broadcasting: We can not broadcast on Universal Serial Bus, only individual messages can be communicated here, between host and peripheral.
