The main purpose of the USB flash drive is to store data. After the efforts of enthusiasts and businesses, the USB flash drive has developed more functions: encryption USB flash drive, boot USB flash drive, antivirus USB flash drive, temperature measurement USB flash drive and music u disk and so on. The following is an analysis of various professional flash drive functions:
Advertising U Disk
the first sort:
The advertising U disk is the reader pre-stored a business website URL, which has any function of the ordinary U disk. When the website U disk reader is plugged into the USB port of the computer, the computer will automatically enter the business website URL immediately.
The second category:
After the customer’s LOGO can be processed by digital color printing, various color effects can be formed, and the sub-bright effect can also be processed.
Boot USB flash drive
The first category: a functional U disk specially used for system startup. When the computer cannot be turned on normally for a while, it enters the system to perform related operations, and the function is relatively single.
The second category: a powerful and functional U disk specially made by the computer city or computer technicians to maintain the computer, in addition to starting the computer. You can also perform functions such as disk partitioning, system antivirus, system repair, file backup, and password modification. It is more suitable for people with certain technical skills, and you can also add some functions yourself, such as a one-click installation system.
Flashing U Disk
The first category: This kind of U disk can add a special luminous material to the U disk shell, which is similar to the effect of glowing light sticks. Relatively simple but very practical.
The second category: This kind of U disk draws a set of power supply circuits through the PCB board of the U disk to supply power to the light-emitting device. There are many types of light-emitting devices that have LED lights, LED screens, and small bulbs (but very few See). This kind of U disk can only emit brilliant brilliance after being inserted into the computer.
Encrypted U Disk
The first category: hardware encryption technology. This technology is generally used to install cryptographic devices through the shell of the USB flash drive. Like the password boxes we use daily, generally this kind of USB flash drives are made of ABS or metal materials, which play a certain protective role. .
The second category: software encryption technology. This technology mainly relies on programming technicians to write various encryption software to encrypt the U disk. Generally, the program is written into the U disk through mass production tools to prevent formatting, deletion and other operations. Only enter the correct password to operate.
Waterproof U Disk
Waterproof USB flash drive: This kind of USB flash drive is rarely sold in the market. Generally high-end luxury goods, only for business people. Generally, the process has been waterproofed: the shell is waterproof, and the USB is isolated from the PCB board.
Temperature measurement U disk
The first type: This type of temperature display is to install a software on the computer to test the temperature in the U disk, and through the software, the temperature obtained by the U disk is sensed. This method relies on computer software to test the temperature.
The second category: This method directly encapsulates the temperature testing hardware in the U disk and directly displays it on the U disk output LED screen. The software has been encapsulated in the hardware.
Music U Disk
The music USB flash drive is an existing USB flash drive with all the storage functions and also has the playback function of music files. The appearance of a general music USB flash drive is no different from that of an ordinary USB flash drive. The difference is that it has a built-in battery and an extra jack for connecting the equipped earphones. After plugging in, you can listen to common MP3, WMA, etc. Format music, support the selection of up and down music playback, and can set the random playback function.
The advantage of the music USB flash drive is that it has the music playback function compared to the ordinary USB flash drive, and has the advantage of low cost and affordable compared to MP3. It is a new generation of mobile storage products that extend and develop the functions of the USB flash drive.
Antivirus U Disk
Anti-virus U disk is a kind of U disk version of various anti-virus software embedded in the U disk, making the anti-virus software easy to use, safe and easy to operate. After connecting with the computer USB interface, it will be recognized by the host without tedious installation. And a new drive letter will automatically appear under “My Computer”, and the anti-virus U disk version will run automatically. The anti-virus U disk is divided into two types in terms of performance: write-in and embedded. The write-in antivirus program must be installed in the computer to achieve antivirus effect; while the embedded antivirus program is written in the control chip of the U disk, and it does not need to be installed and can be antivirus at any time.
In fact, among the bootable U disks mentioned above, the anti-virus U disk is actually one of the bootable U disks. But the anti-virus U disk is dedicated.
