but I can tell you very accurately that hard disks will be replaced by flash disks in the future, that is. Flash memory access is faster, noiseless and less heat dissipation. If you buy it, you can actually buy flash memory without considering so much. If the hard disk space is large, buy a hard disk, which can also meet the needs of your application.
question 2: what are the differences and similarities between a flash drive and a USB flash drive? 1. The difference is that one is a flash drive and the other is a USB flash disk, with different names; Because of the word flash, it is also called flash disk.
2. The similarities are: flash drives and USB flash drives are the same thing;
Question 3: What is a flash drive? What is a flash drive?
In layman's terms, it is a common U disk.
A flash drive is a storage method based on flashmemory and with u *** as the interface. As soon as flash drives appeared, they were considered as "the terminator of floppy disks" by people in the computer industry.
the storage capacity of flash drives is increasing day by day. At present, each flash drive of the highest level can hold the information equivalent to 15 floppy disks. Flash disk technology has also been used in new fields such as digital cameras and walkman.
question 4: what is a flash drive? How to use it? Flash drive is also commonly called flash drive, USB flash drive and U disk.
Flash drive is a micro high-capacity mobile storage product with USB interface of universal serial bus, and its storage medium is Flash Memory. The flash drive does not need an additional drive, and the drive and storage medium are combined into one, so long as it is connected to the USB interface on the computer, it can independently store reading and writing data. Can be use for storing data file of any format and conveniently exchanging data between computers. Flash drives are very small and light, about 15 grams, especially suitable for carrying around. There is no mechanical device in the flash drive, which has strong seismic performance. In addition, the flash drive has the characteristics of moisture-proof, antimagnetic, high and low temperature resistance (--4°C ~ +7°C), and has good safety and reliability. The use of the flash drive is very simple and convenient. Any computer that supports Windows 98/Windows Me/Windows 2/Mac OS and USB can use the flash drive. The steps are as follows:
1) Plug the flash drive into the USB interface of the computer;
2) The system will automatically identify and generate a removable disk (Windows 98 requires a driver);
3) Then you can use the flash drive just like a floppy disk or a hard disk.
Features of flash drives
Flash drives can be used to exchange data between computers. In terms of capacity, the capacity of flash drive can be selected from 16M to 2GB, which breaks through the limitation of floppy drive of 1.44M. In terms of reading and writing speed, the flash disk uses USB interface, which greatly improves the reading and writing speed compared with floppy disk. In terms of stability, the flash disk has no mechanical read-write device, which avoids the damage caused by the easy collision and falling of the mobile hard disk. Some models of flash drives have encryption and other functions, making users more personalized. Flash drives are compact and easier to carry.
what is the difference between a flash drive and a flash card?
The flash drive is directly used for computers and is easy to use. Other Flash memory products (Compact Flash, Smart Media, Multimedia Memory Card, Memory Stick, Secure Digital Card) need a driver to connect to the computer.
what is u *** 2.?
u *** 2. is a new version of u *** technology. The transmission rate is as high as 48mbps, which is 4 times that of u *** 1.1. Suitable for new high-speed peripherals. It inherits the ease of use of u *** 1.1, plug and play, no need to install drivers, and is fully compatible with u *** 1.1 standards. The u *** 1.1 devices and cables you have purchased can still be used.
(Note: According to a new standard, USB2. can be divided into u *** 2. high speed, u *** 2. full speed and u *** 2. low speed, of which only u *** 2. high speed is the real original USB2.)
What are the reading and writing speeds of USB 1.1 and USB 2. respectively?
the reading speed of USB 1.1 flash disk is generally 63KB, and the writing speed is generally 52KB；;
the reading speed of USB 2. is generally 1.5MB, and the writing speed is generally 1.MB.
can you connect the u *** 2. device to the u *** 1.1 interface?
yes, but due to the speed limitation of u *** 1.1, the effect of USB2. cannot be exerted.
can I use both u *** 2. and u *** 1.1 devices?
yes, u *** 2. devices can be stored with u *** 1.1 devices.
can u *** 2. devices be used in os 9.x system?
yes, but the driver must be installed; However, these operating systems do not support u *** 2., and the device can only work in u *** 1.1 mode
in these systems. Can it run other applications when reading and writing flash drives?
yes.
how many times can a flash drive be erased? How long can the data in the flash drive be saved?
the flash drive can be erased 1,, times, and the data in the flash drive can be saved for 1 years.
How many flash drives can a computer connect at the same time?
theoretically, a computer can connect 127 flash drives at the same time. however, due to the sorting of English letters of drives and the fact that the existing drives need to occupy several English letters, only 23 flash drives (except A, B and C) can be connected at most, and the assistance of USB HUB is needed.

Question 5: What does 16g flash memory mean? 16G flash memory usually refers to a ROM that can be read and written, and can store and delete things, which is similar to the nature of a U disk.
question 6: what does flash memory mean? flash memory: it is a mobile hard disk, which is often referred to as a USB flash drive. It can store data and things, which can be copied and stored on other computers. It is called flash memory because of its fast reading and writing speed, and its types are: USB flash drive, TF card, SD card, SM card and so on. . .
memory: it is a temporary storage place in the computer when working. It can only be used on the computer, and it is not allowed to store data directly. It is one of the important components in computer, and it is a bridge to communicate with CPU.
question 7: what is a flash drive and how to use it? Flash Card Flash card is a memory that uses Flash Memory technology to store electronic information. It is generally used as a storage medium in digital cameras, palmtop computers, MP3 and other small digital products, so it looks like a card, so it is called a flash card. According to different manufacturers and different applications, flash memory cards include SmartMedia(SM card), Compact Flash(CF card), MultiMediaCard(MMC card), Secure Digital(SD card), Memory Stick (memory stick), XD-Picture Card(XD card) and MICRODRIVE. Although the appearance and specifications are different, the technical principles are the same.
CF card
Compact Flash was first introduced by SanDisk in 1994. CF card has PCMCIA-ATA function and is compatible with it; The weight of CF card is only 14g, which is only the size of a cardboard match (43mm x 36mm x m3.3mm). It is a solid product, that is, it has no moving parts when working. CF card adopts flash technology, which is a stable storage solution and does not need batteries to maintain the data stored in it. For the stored data, CF card is more secure and protective than the traditional disk drive. It is 5-1 times more reliable than traditional disk drives and type III PC cards, and the power consumption of CF cards is only 5% of that of small disk drives. These excellent conditions make most digital cameras choose CF card as their preferred storage medium.
MMC card
MMC(MultiMedia Card) card was introduced by Siemens and SanDisk, which pioneered CF in 1997. In January 1998, fourteen companies jointly established the MMC Association (MMCA for short), and now it has more than 84 members. The development goal of MMC is mainly aimed at digital images, music, mobile phones, PDA, e-books, toys and other products. It is claimed to be the smallest Flash Memory storage card in the world at present, with a size of only 32 mm x 24 mm x 1.4 mm. Although it is thicker than SmartMedia, its overall volume is smaller and lighter than SmartMedia, only 1.5g.. MMC also puts the storage unit and the controller together on the card, and the intelligent controller makes MMC ensure compatibility and flexibility.
SD card
SD card (Secure Digital Memory Card) is a new generation memory device based on semiconductor flash memory. The SD card was jointly developed by Panasonic, Toshiba and SanDisk Company in August, 1999. The SD memory card, the size of a stamp, weighs only 2 grams, but it has high memory capacity, fast data transmission rate, great mobile flexibility and good security.
the SD card combines SanDisk flash memory card control with MLC (multi-level cell) technology and Toshiba .16u and .13u NAND technology in a volume of 24mm×32mm×2.1mm It is connected with a special driver through a 9-pin interface, and no extra power is needed to keep the information memorized on it. Moreover, it is an integrated solid medium without any moving parts, so there is no need to worry about the damage of mechanical movement.
SM card
SM(Smart Media) card is a Flash Memory card released by Toshiba in November 1995. Samsung purchased the production and sales license in 1996, and these two companies became the main SM card manufacturers. In order to promote SmartMedia to become an industrial standard, SSFDC forum (SSFDC is Solid State Floppy Disk Card, in fact, SmartMedia was originally called SSFDC, and it was renamed SmartMedia in June 1996 and became a registered trademark of Toshiba) was established in April 1996. The SSFDC Forum has more than 15 members, including many big manufacturers, such as Sony > >
question 8: 2GB memory+＋8GB flash memory? What do you mean? 2G memory refers to running memory, which is equivalent to computer memory
while 8G flash memory refers to storage space, which is equivalent to hard disk. The built-in storage is all memory chips, not memory cards, which are faster than memory card blocks
Question 9: What's the difference between flash drives and ordinary U disks? Flash drives are called media hardware disks (mp3 \mp4). They can store files, process media files (music \ videos, etc.) and store some other files, and then bake them to your own computer. U disk is only a hard disk for storing data and files, but not for processing corresponding files. If you want to process them, you have to bake them and put them in your own computer.
Question 1: What does flash memory mean? Flash Memory is flash memory, which can also save data when power is off, which is equivalent to a set of chips, and the hard disk is equivalent to the disk on the computer we are currently using. Hunger can't use technical terms.
but I can tell you very accurately that hard disks will be replaced by flash disks in the future, that is. Flash memory access is faster, noiseless and less heat dissipation. If you buy it, you can actually buy flash memory without considering so much. If the hard disk space is large, buy a hard disk, which can also meet the needs of your application.
