The difference between a hard disk and a floppy disk, a hard disk and a floppy disk in a computer

A floppy disk is a one-inch disk, with a general capacity, and a floppy disk drive needs to be installed on the computer when using it. It is basically not used now.

The hard disk is where the computer stores data, and all the files on the computer are stored in the hard disk. It is an important accessory in the computer. The capacity is generally 80g, 120g, 160g, 200g, 250g, 320g, 500g, etc.

1g=1024mb, 1mb=1024kb, 1kb=1024 bytes, save one Chinese character for every two words, and 1k can store 512 Chinese characters.

If you don't even know what to do with hard disks and floppy disks, then it is recommended that you go to an Internet café to do network management for a few days, and then you will know after repairing the machine yourself, let alone assembly...

You don't have to pay compensation if something breaks down there...

Hard disks and floppy disks are both storage, but floppy disks have been eliminated due to the small disk space, and the storage used in computers today is generally hard disks.

The floppy disk is equivalent to the previous U disk, but the capacity is too small and has been eliminated by the U disk. Hard disks are the most common drives for storing data.

are all storage data, the principle is similar, floppy disks need to be used with floppy drives, a plastic package that looks inch wide has a plastic disc coated with magnetic powder box, very thin, the hard disk is as wide as the floppy disk, but it is encapsulated in a thick aluminum box surface disc and motor reading mechanism are associated together, due to advanced technology, large capacity and fast speed is now a necessary part of the computer, the current mainstream installed hard disk capacity is 250g, the floppy disk is no longer used, the capacity is small and inconvenient to carry, The original function for exchanging data has also been replaced by USB sticks.

Floppy disks have retired from the stage of history

The hard disk is to store all the software you use the computer, the floppy disk is equivalent to the U disk used now, the floppy disk has a small capacity, and it is no longer used.

The difference between floppy disks and hard disks: hard disks are responsible for storing data in the chassis, while floppy disks are used to carry data, the capacity of hard disks is large, and the capacity of floppy disks is small, this is the difference between them, and the access speed of hard disks is much faster than that of floppy disks.

What is a floppy disk, a hard disk The floppy disks seen now are all inches, usually referred to as 3 inches. The 3-inch floppy disk has a plastic-modified fuel shell, which is relatively hard, and its function is to protect the platter inside. The platter is coated with a layer of magnetic material (such as iron oxide), which is the medium through which data is recorded.

There is a protective layer between the housing and the platter to prevent the abrasion of the enclosure to the platter.

A hard disk is a primary computer storage medium consisting of one or more discs made of aluminum or glass. 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.

Floppy disks and hard disks in computersIn the early days, there were no hard disks and optical drives, only floppy drives. The floppy drive is divided into two types: inch and inch, of which the former has been eliminated and the latter continues to be used, which is what we see now.

In the early days, computers were powered on floppy disks, and applications and user files were also installed on floppy disks. For ease of use, a computer can be fitted with two floppy drives, which are defined as the A and B drives. If the hard disk is partitioned or multiple hard disks are installed, their drive letters will be postponed in turn, and they will be defined as D drives, E drives, etc.

A floppy disk is a piece of hardware that stores data, and software is an application.

A hard drive is also the hardware that stores data.

Floppy disks are generally rectangular disks of inches. The capacity is and can be carried. Smaller documents are generally stored.

When using, plug it into the floppy drive of the computer, and then access the A disk. With the development of computer technology, floppy disks have been gradually replaced by U disks, and now the computers produced are basically without floppy drives, of course, users need exceptions.

Hard disks are indispensable hardware for a computer, and the size is generally more than 40MB, and there are older hard disks that are lower than this. A hard disk is a piece of hardware that stores files and can be partitioned, such as C drive, D drive, etc. Generally, the operating system of the computer is installed in the C disk by default, such as the Windows series software we use.

If you don't have a hard drive, your computer won't boot. All in all, all the programs and files in the user's computer operation are installed on the hard disk, and our ** files are also installed on the hard disk. Of course, hard drives are inconvenient to carry unless you disassemble the machine:

The lack of a floppy disk in a computer doesn't make a big difference, but the lack of a hard disk equals a computer model (not useful :)).

In terms of access speed, hard disks are faster than floppy disks.

The difference between floppy disk and hard disk: the main body is different, the principle is different, and the characteristics are different.

First, the subject is different.

1. Floppy disk memory: It is the earliest removable medium used in personal computers (PCs).

2. Hard disk memory: It is a classification of disk memory. Storage that uses disks as storage media.

Second, the principle is different.

1. Floppy disk memory: Reading and writing is done through the floppy disk drive. Floppy disk drives are designed to receive removable floppy disks.

2. Hard disk memory: It is an auxiliary memory that uses magnetic recording technology to store data on a rotating disk coated with magnetic recording medium.

Third, the characteristics are different.

1. Floppy disk memory: It must be formatted before use, and after completing this process, the disk is divided into several tracks, and each track is divided into several sectors.

2. Hard disk memory: It has the characteristics of large storage capacity, high data transmission rate, and long-term storage of stored data.

There are two main categories of internal memory and external memory:

The internal memory is in direct contact with the CPU and is responsible for the operation of various software. External memory includes floppy disks, hard disks, optical discs, tape drives, etc. Hard disks and floppy disks are very similar in that they work in much the same way, except that the floppy disks are separate from the floppy disk drives, while the hard disks are housed together with the hard drives.

All the platters in the hard disk are mounted on a rotating axis, each platter is parallel to each other, there is a magnetic head on the storage surface of each platter, the distance between the magnetic head and the platter is smaller than the diameter of a human hair, all the magnetic heads are connected to a magnetic head controller, and the magnetic head controller is responsible for the movement of each magnetic head.
