What is a network electronic hard disk and the difference between an electronic disk and a hard disk

Do you use QQ? QQ has a free 16MB network hard drive.

I'm using a 100mb vdisk

It's some ** provided network space, which can be used to store some software, and you can upload what you are storing.

I haven't really heard of it, but I've heard of it: electronic hard drives.

DOM (generally refers to IDE electronic hard disk), composed of control unit (controller) and storage unit (FASHIC), simply put, it is a hard disk made of solid-state electronic memory chip array, and the most common electronic hard disk is Flash electronic hard disk. We call it an electronic hard drive because its interface specifications and definitions and usage methods are exactly the same as those of ordinary hard drives. Includes:

IDE, SCSI, FIBRE CHANNEL, etc. The shape and size of the product is also completely consistent with ordinary hard drives, including:", ", "Multiple types. Because the electronic hard disk does not have the rotating medium of the ordinary hard disk, it has excellent shock resistance, and at the same time the working temperature is very wide, and the electronic hard disk with extended temperature can work at -45 +85

First, the composition is different.

1. Electronic disk: semiconductor chips.

to store data.

2. Hard disk: It is composed of one or more aluminum or glass discs.

Second, the characteristics are different.

1. Electronic disk: It has the characteristics of small size, low power consumption and strong shock resistance. Embedded systems.

It is common to use a variety of electronic disks as external memory.

2. Hard disk: It is composed of a group of overlapping platters, each disc is divided into an equal number of tracks, and is numbered from the disadvantage "0" on the outer edge of Qibubu, and the tracks with the same number form a cylinder.

Third, the advantages are different.

1. Electronic disk: often used in special machines and industrial control machines. It uses IDE ATA industry-standard control technology, which requires no additional or patented software, eliminating the need to modify settings, making it easier to operate and more flexible.

2. Hard disk: used in home and enterprise computers to store data.

Analysis: What is a "hard drive"?

Update time:2005-2-10Hard disk is a major computer storage medium, consisting of one or more aluminum or glass discs. These discs are covered with ferromagnetic material.

The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive. However, now removable hard drives are becoming more and more popular, and there are more and more types.

The vast majority of desktop computers use either IDE or SCSI interfaces for hard drives. The advantage of SCSI-interfaced drives is that up to seven different devices can be connected to the same controller panel. Since the hard disk rotates at a constant high speed of 3,000-10,000 revolutions per second, it only takes a short time to read data from the hard disk.

In laptops, the hard drive can stop spinning when idle in order to extend battery life. Older hard drives have a minimum storage capacity of 5MB and use discs up to 12 inches in diameter. Today's hard disks have storage capacities of up to tens of gigabytes, and the diameter of the disks used in desktop computer hard disks is generally inches, and the diameter of the disks used in laptop hard disks is generally inches.

New hard drives are typically low-level formatted in the assembly plant to store some of the original sector identification information on the hard drive.

"Network hard disk" is an exclusive storage space, users can easily upload and upload files by logging in online, and the unique sharing and grouping functions break through the concept of traditional storage.

Compared with other similar products, the "network hard disk" product has four characteristics: intuitive preview, four-level sharing, group management, and stability and security.

Network hard disk refers to the "remote hard disk space used by network connection management", which can be used to transfer, store and back up computer data files for easy management and use. Users of this site can connect to use the network hard disk service provided by "eNetcom" on any computer terminal with Internet access in the world.

It is the external memory device of the computer, that is, the round magnetic platter is packed in a square sealed box, and the purpose of this is to prevent scratches on the surface of the disk, which can lead to data loss.

1. Open my computer and find the disk or file we want to share, here if we share F drive;

2. Right-click the F drive and select "Share" - Advanced Sharing".

3. Tick the box in front of "Share this folder" at the top of the dialog box, and then click "Permissions";

4. Here we can set permissions for users who view the sharing according to our own needs, and finally click OK in turn, and the sharing will be set successfully.
