Main Difference between memory and hard disk
The architecture of a computer is a complex system and there are many terms that, although they seem very similar, are different from each other with the slightest variation. There are many devices in a computer hardware that perform various functions but they are interrelated and two of these devices are known as hard disk and memory. The differences between them will be discussed in this space. The main one is that a hard drive is a device that stores memory, while memory is information that is stored on a hard drive. Memory on a hard drive can be stored magnetically only while information on a memory device is stored in the form of electrical signals and data.There are also other ways to show this difference, for example a memory can be lost when it is turned off. energy, but it can still exist if it is stored on a hard drive. Another way to tell the difference is that updating memory space is a relatively difficult process, while adding another hard drive to the computer is a straightforward process. There are many other differences that will be explained at the end, while a detailed explanation of both types is given in the next two paragraphs.
Comparison table difference between memory and hard disk
|Definition||The process in which information is obtained and stored and then encoded so that it can be obtained at a later time.||This is a data storage device that is used to store and access the information that is present on the computer.|
|Data loss||can be lost in most cases when the power is turned off immediately||Everything in it stays there in case of power shortage|
|Information||The data is stored on a memory card in the form of electrical formats.||The data is stored on a hard disk in the form of magnetic memory|
This is a data storage device that is used to store and access the information that is present on the device, it is entered into the device by the user who wants to keep it in a place where it can be accessed at any time. This can be done in the form of folders and files while information such as documents, videos, audio, and even images. The structure is simpler where the rotating discs that are coated with magnetic material are placed. These are connected with magnetic heads that are placed on the movable arm that helps to read and write the data. This data is accessed through RAM, which means that the information that is present on the device can be opened without proper sequence. It was first introduced in 1956 and has grown in space over the years. It has been produced by more than 150 companies over the years, but the most famous are Seagate and Toshiba. The normal hard drive size is 3.5 inches for computers, while the size of a laptop is around 2.5 inches. USBs are the devices that have originated from hard drives and are gaining popularity.
In simple words, memory is the process in which information is obtained and stored and then encoded so that it can be obtained later. This allows information from external sources to be properly organized, this data is transformed into codes that are only understood through encoding and gives you a safe space to exist where it cannot be lost. This is computer hardware that is used to store information in such a way that the computer can use it at any time and the functions continue to run. Memory is operated at high speeds and can exist in various places such as RAM and hard disk, there are different cases in which memory is used and is kept safe in these devices which will not be favorable to discuss in this space.
- Memory can be lost in most cases when power is turned off immediately whereas if memory is on a hard drive it will not be lost.
- The hard drive is the device that stores memory, while memory is the information that is stored on a hard drive.
- Memory helps the computer run faster, while the hard drive does none of these functions.
- Data is stored on a hard drive in the form of magnetic memory, while it is stored on a memory card in the form of electrical formats.
- Upgrading memory space is a relatively difficult process, while adding another hard drive to the computer is a straightforward process.
The two terms Memory and hard disk are different in operation and functions. This article, therefore, provides a proper understanding of the two types so that people have a clearer idea. The task is accomplished by adding more differences and giving more details on the topic which will hopefully be helpful.
