What Is USB and Types Of USB

The USBs are becoming an essential part of our daily lives. It is a great way to share your favorite photos, videos, and music with others. In addition, they can be used for many purposes like backing up data or transferring files between computers. 

There are two types of USBs: the old USB 1 and the new USB 2. The newer version has high-speed transfer rates that allow users to download large files in minutes rather than hours! 

What is USB?

USB, or the Universal Serial Bus, is a connector design that provides power and

data over a single cable. It was created to standardize many devices, such as printers, cameras, and keyboards with PCs.

It was invented by Ajay Bhatt when he joined Intel in 1988.

Lately, Universal Serial Bus has replaced the Advanced Technology Attachment and Parallel ATA as the main method of attaching external peripherals to PCs.

This form of connectivity is used on many devices, including printers, scanners, hard drives, mice, keyboards, and CD players.

It makes it easier to connect and share data between any two devices with a USB cable instead of using different cables for each device.

You can even attach more than one peripheral device to your computer at once using this technology!

Types Of USB

Types of USBs include:

-USB 1.0, which is the original release, and USB 2.0 with a transfer speed of up to 480 Mbit/s

-USB 3.1, with transfer speeds up to 10 Gbit/s

-USB Type C (releases in 2015), an upgrade from the previous versions

-Micro USB, for use with devices such as PDAs and smartphones; typical transfer speed is 12 Mbit/s

-Lightning Plug, for use with Apple’s iPhone 5 connector; typical transfer speed is 480 Mbit/s

-USB OTG (on the go), which allows users to use a USB device as the host, connect that device to another USB device such as a digital camera, plug in a keyboard or mouse, and operate both devices at once

-UBS Mini, used for PDAs and smartphones

-USB 3.1 Type C connector (releases in 2015)

-Micro USB 2.0; typical transfer speed is 480 Mbit/s

-Mini USB 2.0; typical transfer speed is 480 Mbit/s

USB 1.0:

USB 1.0 was released in 2000 and was the original release of what we now call USB.

USB 1.0 is similar in size to a modem or ethernet port, and the speed it transfers data at an average of 12 Mbit/s.

USB 1.0 was superseded by USB 2.0, which was faster and could also transfer power and data.

USB 2.0:

Introduced in April 2000, more commonly known as Hi-Speed USB (or HS), it can be plugged into a computer or other device using its A-type connector (in what is called the “A” end) or into an external hub that splits the signal between several devices at what is called the “B” end. Together with version 1.1, this is commonly referred to as USB 2.0, although they are separate specifications with different wire diameters and protocols. 

Typical transfer speeds are 480 Mbit/s; max throughput of 60 MB/s per port; 12 Mbit/s per device.

USB 3.1:

Introduced in July 2013, it has a transfer rate of up to 10 Gbit/s (10 × 109 bit/s), ten times faster than the 480 Mbit/s standard speed possible with earlier USB versions. 

In addition, it can handle files larger than 4 GB without any special preparations on the host or filesystem-level and uses efficient package encoding techniques to minimize transmission overhead. 

The new cable is also reversible, similar to that used by many newer mobile phones, which allows for easier hookup.

Typical transfer speeds are 10 Gbit/s; max throughput of 625 MB/s per port; 12.5 Mbit/s per device.

USB Type C:

A new version will be launched in 2015, which could see even more impressive improvements, including doubling the current USB 3.1 speed to 20 Gbit/s, faster charging, and delivering power up to 100W through what is being called a “power delivery over the cable” feature. It also uses smaller connectors. This version is typically just referred to as “USB-C.”

Micro USB:

Micro USB is a common type of miniaturized USB connector used on small devices such as cell phones. It is also known as the “USB 2.0 Mini-B” connector and is often referred to simply as “mini USB.”


The Mini-A (sometimes written mini-A or MINI A) connector as specified in the original USB 1.1 standard released in 1996 but not commonly used until the introduction of Hi-Speed USB, where it was alternately labeled Type B.


The Mini-AB receptacle combines both what we now call the Micro-B and Mini-B connectors into what we currently know as a single device port. It can be used for what we know as Type A or what is now called the Micro-B connector. 

Although this newer port provides power to devices at a lower voltage than what is possible with what is currently the Micro-B port, it must be used on devices that have been designed specifically to use what is now what we call the Micro-B port since the Mini-AB device plug has many more pins which would cause damage to devices designed for what we currently know as just a normal micro USB plug.

Typical transfer speeds are 480 Mbit/s; max throughput of 60 MB/s per port; 12 Mbit/s per device.

Lightning Plug:

The Lighting plug is what Apple calls the connector used by what we know as the iPhone 5 and later devices. This new port has been redesigned to support what Apple calls “adaptive” charging. 

That feature allows for what they call a “dynamic current load sharing between device and charger,” where the charge rate dynamically changes depending on what it needs at any given time.

Typical transfer speeds are 480 Mbit/s; max throughput of 60 MB/s per port; 12 Mbit/s per device.


“On-The-Go” is what USB OTG (also known as a USB host or USB device) devices use to connect themselves to what we know now as a normal A-type connector. 

These new devices allow us to do what we currently refer to as “thumb drives” and use them with what we commonly refer to as our cell phones. It uses an external power supply for both the high speed of 480 Mbit/s data transfer rate and what is called full speed operations of 12 Mbit/s.

Typical transfer speeds are 480 Mbit/s; max throughput of 60 MB/s per port; 12 Mbit/s per device.

What is a USB Cable?

USB Cable is what connects your electronic device to a power source.

It can also act as an extension cable, allowing more devices to be connected to one outlet. 

The USB cable usually comes with a phone or tablet charger and is shaped according to what type of connector they have on each end.

You may find that most smartphones and tablets use a Micro-USB connector, which is rectangular and thin at 5 mm by 2mm. This USB connection is now found worldwide in various types of devices such as TVs, hard drives, keyboards, and mice.

Types Of USB Cables

Many cables types can be used to connect USB devices. Each cable type is designed for specific purposes; what these cables can safely do will vary.

-Type A is typically designed for plugging into an electrical outlet and powering a device.

-Type B is typically what you would use for connecting a device to your computer for file transfer or streaming media.

-Type C is what you would want if you wanted to charge and sync your device with a single cable.

Type-A USB Cable:

This is what we refer to as what is called a standard USB connector. It was the first type of connector and uses what we know to be called an “A” type of miniaturized USB plug.

These types of plugs and connectors are also what allow us to what is called “hot-plug” or what is now referred to as our phone or what we call a “tethered PC.”

The main use for this type of cable is what we currently know as connecting what some people call a “USB-powered device” with what some people call a charger or what other people refer to it as what they would say “wall power.”

Other than that, the Type A connector has also what is called what we call what is what we call an “A-to-A,” what people refer to as a short cable.

It’s what we use for what they sometimes do, what some people refer to as what sounds like it could be what someone would describe as attaching something described to them as a what is known as a flash drive or an external hard drive.

Mini-A USB Cable:

This is what some people know as being what we refer to as forward compatible with many different types of legacy ports. This particular Type was meant for use with external hubs or when connecting displays or printers what they call what we refer to as what you say what is known by some people as being what they would describe as an “A-B.”

Type B USB Cable:

This type of USB connector was used in the past with what is now referred to today as legacy devices.

The plug was also deliberately designed to prevent unauthorized connection, if you can imagine that. It has two rectangular metal prongs, and the socket opening for this kind of connector also had two grooves at 90 degrees where none of what we refer to as what we call the plastic housing had been inserted fit only in one way.

The Type B connector also has what some people would describe as what sounds like what someone might describe as an “A-B,” which is referred to by some of them as a cable.

This type of cable is used to connect legacy devices, or what we sometimes call legacy ports on external hubs, printers, and two that you may refer to as display screens.

Micro-B USB Cable:

This what we refer to as what they call a new what some people would describe as being what they say is called “B” connector. It can be inserted in either orientation, and it’s much smaller than what the older types of connectors were.

Mini-B USB Cable:

This was designed to make the Type B connector obsolete but didn’t quite succeed. So this type of cable was meant if you can imagine that, to what is what we call what they say what is referred to as being what some people might describe as “backward compatible.”

Type C USB Cable:

This type of USB connector has become more popular recently because its symmetrical design allows it to be easily inserted into the receptacle without looking at what each side looks like when you pair them up together.

These types of connectors can be what some people might describe as what someone would refer to as being what is known by what they call a “USB-powered device.”

As I have just mentioned, this type of connector can only be inserted into the host or what we know to connect them in what is called and what you may describe as its receptacle.

While there are inserts for each connector, there is just one “Type C” housing. The Type C ports found on newer computers use what we call an Alternate Mode. Thus, they can support video output along with USB data transfer rate.

Pros and Cons Of USB :

USB is mainly used for two things: it is a cable standard for transferring data and a power supply. In addition, USB cables are what allow your computer’s drives and peripherals to connect to what they need. There are different USB cables, including Type A, Type B, Type C, Micro-B, Micro-A.


– Cheaper price

– Easily found online or in stores

– Great for transferring data between devices

– USB ports are what connect your device to a power source.

– USB cables are what allow more devices to be connected to one outlet.

-the most popular types of connections for USB cables are the Micro-USB connector, rectangular and thin at 5 mm by 2mm.


– Short cables unusable with tablets or high up monitors

– Length can be an issue for the other devices that you have connected to your desk.

– It uses more power than what is necessary.

– The USB cable only connects your device to a power source and does not provide any data transfer capability.

– It is what charges your phone or tablet battery but what in turn makes it noticeably run slower.


USB stands for Universal Serial Bus and is a short-range, high-speed data connection. It was developed in the early 1990s to connect devices such as computers or printers without using an Ethernet cable.

There are three types of USB cables that you can use depending on your needs, which we will cover below. 

The advantage of having these types available is that it provides flexibility when connecting different devices because there are many variations, with some being widely compatible while others may be more specialized.

Disadvantages include not all connections being “plug and play.” Hence, they require manual configuration before they work properly, possible issues during transmission if the device isn’t plugged into a power source and lacks a password.
