The life of a modern person cannot be imagined without using a computer. For the accumulation and storage of information, its transfer and exchange, as well as the loading of operating systems and backup, special devices are widely used today-flash drives or, correctly, the USB flash drive. They are connected to a computer via a USB slope-a special hole in the system unit.
Typically, the flash drive has a small cap, necessary to protect its “working” part, but it may be absent. In this case, the mechanical connector is pushed into the case through a special slider. Some flash drives have a lace that allows you to wear them on the neck.
Today they come in a variety of sizes and shapes. Many people prefer carriers in the form of a toy, a pocket knife or keychain keychain.
The popularity of flash drives is associated with a number of their undeniable virtues:
Little weight (about 60 g).
Portability.
Simplicity of use.
Universality (approaching any computer).
Low power consumption.
Preservation of information for a long time.
Energy dependence.
The ability to work at different temperature conditions.
Reusability and overrunage.
Filming.
Durability.
High speed of work.
Resistance to vibration, dust, blows.
However, the use of flash drives has a number of disadvantages:
The number of erasing cycles is limited.
Electrostatic discharge vulnerability.
Weads of USB-shares due to frequent connection-shutters.
Today you can record from one to several dozen gigabytes of information on a USB flash drive. Its amount depends on the amount of memory. Another important quality is the recording speed, it is it that dictates the time required to transfer information. The most modern models have a speed of up to 20-30 MB/s. It depends on the speed of data reading speed how quickly information is tolerated from the flash drive to the computer, it can reach 30-35 MB/s.
Currently, flash drives are produced by various shapes and sizes, differ in the case material and ways to protect information (for example, some of them allow you to protect data with a password), as well as a variety of additional functions.
It is simply impossible to imagine a modern society without using flash drives, they cease to be only a device for storing information and have become an integral part of a person’s life.
