Question 1: What is the main function of a computer hard drive? Among all computer components, the hard drive is a data container used to store the software, movies, games, music, etc. we usually install. In a computer, the role of the hard disk is second only to the CPU and memory. Its main function is to store operating systems, programs and data.

With the continuous development of the IT industry, the size and capacity of computer hard drives are being upgraded very quickly. Due to the increase in the update speed of computer accessories, a large number of second-hand hardware has appeared, and second-hand hard drives are one of them. At the same time, there are more and more hard drive brands, such as ASUS hard drives, Seagate hard drives, etc. And there are mobile hard disks that have hard disk functions and are easy to carry. At the same time, the emergence of hard disk boxes also provides convenience for portability. Greatly meet the needs of users.

In fact, the hard drive is also a very fragile device in the computer and needs to be taken care of. Because slight vibrations may cause damage to the hard drive. After the hard disk is damaged, it can be sent to a professional hard disk repair point for inspection, but the data on it will most likely be lost.

If you want to edit pictures, play games or listen to music on your computer, a large-capacity, fast and reliable hard drive is very important. During operation or Internet access, a large number of temporary files may be stored on the hard disk, affecting the running speed. Therefore, regular hard drive defragmentation and hard drive repair work is required. If data is lost during organization or repair, hard drive data recovery can be used to retrieve the data.

Question 2: What is the function of the hard disk? Store data, operating system, programs and other files. When the memory is insufficient, the memory will use a small part of the hard disk as virtual memory to make up for the lack of memory.

Question 3: The main problems of the computer hard disk What is the function? Among all computer components, the hard drive is a data container used to store the software, movies, games, music, etc. we usually install.

Question 4: What is the function of the computer’s hard drive? What is the metaphor? The hard disk is where the system and data are stored, and its second function is as a data cache. storehouse.

Question 5: What is the use of a hard drive? The hard disk is the most important external memory of the computer. It has the advantages of large capacity and fast speed.

The hard disk has many indicators. It is a mechanical component. The indicators include spindle speed and seek time. In terms of performance, there are single disk capacity, internal transfer rate, etc.

Nowadays, the hard disk subsystem is the biggest bottleneck limiting computer performance. Although the hard disk is a faster external memory, its speed is really slow compared to the CPU memory.

So 10,000-rpm hard drives, RAID, and iRAM continue to appear.

After the hard disk speed is increased, the overall performance of the system will be greatly improved.

Anyone who has seen iRAM (using memory as a virtual hard disk) will feel this way. The 3Gb/s speed is unmatched by any hard disk. The time to enter the system, games, and programs is significantly reduced, and the test score is significantly improved. .

Question 6: What is the role of a computer hard drive? Let me give you an analogy: a hard drive is like a warehouse. If there are many goods, the warehouse needs to be large. But if there are few goods, it is meaningless to have a large warehouse. It can be accommodated as long as it is large enough. . Memory is like the aisle leading to the outside of a warehouse, where goods are temporarily stored. Small memory means small aisles, and goods can only be moved in small quantities. The processor is like a porter (moving tool). A powerful processor is like a loader. The amount of goods that can be loaded at one time is large and the speed is fast. Dual core can be understood as two loaders, and the frequency of the CPU is like a loader. speed. . . That's roughly it!

Question 7: What is the main function of a computer hard drive? The core components of a computer include: motherboard, CPU, memory, power supply, and hard disk. None of them will work without one of them

Motherboard: also called mainboard, systemboard or motherboard ( motherboard); it is installed in the chassis and is one of the most basic and important components of the microcomputer

CPU: Central Processing Unit (CPU, Central Processing Unit) is a very large-scale integrated circuit. The computing core and control core of a computer;

Memory: Memory is also called internal memory. Its function is to temporarily store computing data in the CPU and exchange it with external memories such as hard disks. Data;

Hard disk: Hard disk (called hard disk in Hong Kong and Taiwan, English name: Hard Disk Drive, HDD for short, full name Winchester hard disk) is one of the main storage media of the computer, consisting of a or It is composed of multiple aluminum or glass discs. Its main function is to store file data. The files you see on your computer are all stored in the hard disk;

Power supply: this The explanation is very simple. How will your computer run without electricity?

Question 8: What is the role of the size of the hard drive? The hard drive is the external memory of the computer and is used to store data in the computer (movies, files, games, Programs, systems, songs, etc.), hard disk data can be read and written, and will not be lost when power is turned off. The size of the hard disk capacity represents how much data your computer can store. A large hard disk can store more data, while a small hard disk can store relatively less data. , the size of the hard drive is limited by the support of the motherboard. For users like you, a 160G hard drive is too big and is a waste of computer resources. It is recommended that you use this space to back up the data on the hard drive. This will be beneficial to yourself. There are benefits

Question 9: What are the main functions of the mobile hard drive? Hello. Mobile hard drives are mainly used to back up data and expand the computer's built-in hard drive. If you feel that there is important data in your computer that needs to be backed up or the computer's built-in hard drive is not large enough and you have a lot of various types of data that you want to save (such as movies, music, books, etc.) , application installation version, etc.), then you need to buy a mobile hard drive. Since mobile hard drives are very convenient for backing up data compared to burning CDs/DVDs, and have a much larger capacity than USB flash drives, mobile hard drives are now basically standard equipment for computer experts. Please note: The mobile hard drive is not resistant to falling, so you must take precautions to prevent falling whether it is empty or when reading or writing data.

From my personal experience (I have used Western Digital, Seagate and Toshiba, the three major brands of mobile hard disks in my hand, all of which have u*** 3.0 interfaces), I would like to state to you the following:

1. Western digital has better workmanship, average speed and good stability;

2. Seagate has average workmanship, slower speed and better stability;

3. Toshiba's workmanship is not very good, its speed is relatively fast, and its stability is average.

In fact, the quality of the above-mentioned three major brands of mobile hard drives is still acceptable. The key depends on whether you have any preferences. It is strongly recommended that you buy a 1t 2.5-inch hard drive, which is very convenient to carry around and costs about 400 to 500 yuan. Compared with the 1t mobile hard drive, the 500g mobile hard drive is too cost-effective and is not recommended to buy. The prices of the above three mobile hard drives with the same technical specifications are Western Digital＞Seagate＞Toshiba.

At present, a high-definition movie can range from 1 to 2g to 3 to 4g. You can do the math yourself. Even a 1t mobile hard drive (for simplicity, 1t=1000g) can only Stores about 250~500 high-definition movies.

It is also strongly recommended to buy mobile hard drives online, from JD.com/Yixun/Amazon.

Hope this is useful to you.

Thank you.

Question 10: What role does the hard disk play in the host? The role of the hard disk is to store and read data. For example, when you run a game program, you frequently read data from the disk. It is also related to the speed of the hard disk. The faster the speed, the more data is read, so it is very necessary to choose a good hard disk, but it is not the only factor. This also needs to consider the running speed of the CPU, etc. I hope this can help. you! ! !
