Software vs. hard disks, hard disks vs. file systems

Oh, the difference between piracy and genuine is not very big, don't listen to others, how many pirated software are used all over the world, and I haven't seen a few suggestions from me who say that the hard disk is damaged by the software:

1. Do not often read and write a large number of hard disks (such as installing the system and formatting) 2. Frequent anti-virus, viruses may affect the life of the hard disk.

3. Defragment to improve performance.

4. Reasonable planning of files and allocation of resources, for example, virtual memory should not be placed on C disk, but on other disks.

Oh, that's all, I hope you can be happy every day!

What is called piracy is due to you without paying the software developer! This has nothing to do with whether the software breaks the hard disk or not!

And as far as I know, there is no software or virus that can destroy the hard drive

However, some pirated software will have viruses, this can be careful, some viruses will destroy the data on the hard disk, if you want to use pirated software, it is recommended to use Kaba or other anti-virus software before scanning, no virus, basically you can use it with confidence!

To be clear about the concept, pirated software will not damage your hard disk, but only for the genuine modifications, possible damage from the person who modified the software may add malicious other software that may damage the hard disk in the pirated software, this is also relatively rare, more in order to advertise or steal important information and add other software that will not damage the hard disk but will cause damage to the system and personal information.

As long as you operate on the hard disk, you are destroying the hard disk, but the degree of destruction is different, and there is nothing special about the pirated software you said in destroying the hard disk. It's all pretty much the same.

The hard disk has its lifespan, and the important data should not be stored on it, and the engraved disk should be saved.

Look at what software, generally not, use it, as long as you don't drop the hard disk, as long as you don't hit the hard disk when you turn on the machine, the hard disk will generally not break,

Genuine software also hurts hard drives.

A disk is a memory that uses magnetic recording technology to store data. Disk is the main storage medium of the computer, which can store a large amount of binary data and keep the data from being lost even after a power failure.

Floppy disks were the earliest removable media used in personal computers (PCs). The reading and writing of floppy disks is done through floppy disk drives. Floppy disk drives are designed to receive removable floppy disks, and the most commonly used ones are inch-sized floppy disks.

Floppy disks have slow access speed and small capacity, but they can be loaded and detached and easy to carry. As a removable storage method, it is ideal for small files that need to be physically moved.

Hard disk is one of the main storage media of a computer, consisting of one or more aluminum or glass discs. The disc is covered with a ferromagnetic material. Hard disks are mainly divided into solid state drives, mechanical hard disks, and hybrid hard disks.

The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

We all know that the data in the computer is stored on the hard disk, so what is the physical composition and logical structure of the hard disk?

Head (0-1023).

Cylindrical (0-255).

Sector (0-63).

Therefore, the maximum capacity of the disk that can be addressed by the CHS parameter is.

63*512/1048576 = 8064 mb(1m=1048576 bytes)

The program needs to read the data when it runs, and the user needs to store the data in a fixed place, but as a user, you can't directly manipulate the disk, which leads to the file system - a kind of fileAn abstract form of a disk, which means that the file system translates the physical characteristics it comes into contact with into pathnames and file names that the user can see, so that the user can manipulate the file without having to deal with the disk.

Let's use a FAT32 disk in the virtual machine to learn this kind of file system in detail, and first look at the basic situation of the boot sector.

Each part functions

Then, starting with the cluster number 3, if you need to store large files, a cluster linked list is formed, which is formed by writing the next cluster number there, and the last cluster ending is marked with 0x0ffffff

The cluster chain formed above starts from the third cluster to the end of the fifth cluster, and the starting address of the third cluster is [root directory offset + cluster offset = aaa000 + 2000 = aaac00].

The process when storing a file

Disk generally refers to the hard disk, which is equivalent to the drive drive mechanism and the disk disk that are encapsulated Not a hardware floppy disk needs to be used with a floppy drive, the floppy disk is equivalent to the disk in the disk At present, the commonly used is the inch floppy disk with a capacity.

Floppy disks, now computers are not needed, and now there are *** optical drives) hard disk is a necessary storage device for computers, generally 40g, 80g, 120g, 320g, 500g, 1t, 2t, 4t

c d e f is the drive letter of the hard disk.

Floppy disks and hard disks are all disks, which rely on magnetic materials to store data. A floppy disk is a disk inserted into a floppy drive to read, with a small capacity, and the most common is a capacity. Hard disk is one of the necessary hardware in the computer, the disk in the computer belongs to different partitions in the hard disk, the main function of the hard disk is to store data, large capacity, slower than memory.

The disk is the disk with magnetism, and if it is with a magnetic object for a long time, it cannot be used, and the hard disk is the one that can store things in it, and it is divided into mobile hard disk and fixed hard disk, and the disk in the computer is the hard disk.

The disks are old-fashioned storage and are removable. Floppy disks are old-fashioned disks. Floppy disks and disks are retired. It has been replaced by a USB flash drive. A hard disk generally refers to the storage in a non-removable computer.

Floppy disks and hard disks are both disks, which are a storage medium that uses magnetic materials to record data.

Floppy disks were used in early computers, and they were divided into inches and 5 inches for data movement, and have now been largely eliminated.

A hard disk is a fixed storage device installed on a computer, which has a large capacity and is less prone to data loss than a floppy disk. Stable and reliable.

The difference between disk and U disk is that U disk uses flash chip to store data, so the access speed is fast, shock-resistant, and the storage is more stable and reliable. SD cards, memory sticks, and the like all belong to the Flash chip architecture.

Floppy disks are the most primitive types of memory, generally only left or right.

Optical discs are commonly referred to as discs, which generally have a capacity of more than 600 meters, and now there are compressed ones that can reach several g capacity.

Hard disk is one of the important contents of the computer case, now the mainstream is 80G and 160G capacity, the things in your computer are placed in the hard disk, including your system software is under the platform of your operating system, a series of programs that can run, for example, Internet browsers, QQ, a series of games, office software, are software and hardware is all parts of your computer, visible things.

The XP installation disc is a disc.

Maybe you don't understand it, hehe, that's it.

1 Floppy disks are the four-corner, the oldest kind.

2 Discs are VCDs

That's the case. You can install software.,XP installation disk is a CD-ROM 3 Hard disk is the thing that your computer uses to store system and other files,The software of the computer is installed there.4 The software is what you usually use.,Like what office。

qq。These are all software, the former is office software, and the latter is chat software.

5. Hardware is the stuff of your computer, the stuff you spend a lot of money to buy in the chassis.

Of course, the XP installation disk is a CD

The hard drive is the storage device in your machine, and you see the cd e....It's the things on the hard disk, the software is the program that can be installed on your hard disk, and XP is the software.

Hardware is everything you can see in your case, including mouse, keyboard, and monitor, what do you say? As long as Zhang's is the same as VCD, it's a disc disk, and a floppy disk is a disk used in a floppy drive.,Now it's used less, I guess the chance of you seeing it is smaller.

It's very simple, hardware is the configuration of the computer, software is the system of the computer, these two terms are a generalization, abstract, hard disk is the so-called 40G, 80, 120G that kind of root mobile hard disk we usually see, floppy disk is the inch of the thin floppy disk, optical disc is the CD we see every day, VCD, etc., disk is similar to the floppy disk.
