Difference Between Hard Disk and RAM

Hard Disk vs. RAM

The main difference is the memory; hard disk has a large amount of space available for data while RAM has a small memory space.

Hard Disk vs. RAM

The hard disk is used to store data while RAM is used to access data.

Hard Disk vs. RAM

Memory in the case of RAM is a virtual memory while memory on the hard disk is a physical

Hard Disk vs. RAM

Nothing can be stored in a RAM while information can be stored on hard disk.

Hard Disk vs. RAM

RAM is known as Random Access Memory while the hard disk is written as HDD.

Hard Disk vs. RAM

All the system files are stored on the hard drive while there are no system files present in the random access memory.

Definition of RAM

RAM stands for Random Access Memory is part of a computer that allows the information to be stored and retrieved at any time during the running of various processes. In more technical terms random access memory means all the data which is present on the RAM in the form of bytes can be read quickly without stirring the other system bytes. It is different from read only memory in which you can only read the memory but cannot retrieve it. There is two primary type of RAMs which are DRAM known as Dynamic Random Access Memory and SRAM, which is known as Static Random Access Memory. Both have their own uses, but while DRAM has to be refreshed at a higher speed, SRAM does not read any refreshing and is faster than dynamic RAM. The first type used transistors to store the data. The role of RAM is simple, when the computer starts to work most of the memory of the operating system is present on the hard disk and are loaded instantly through RAM. After that, all the applications and web pages that are opened have their own memory and needs to be reached quickly so it is shifted to random access memory.

Definition of Hard Disk

This is a data storage device which is used to store and access information which is present on the device, it is entered into the device by the user who wants to keep it at 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 pictures. The structure is simpler where the rotating disks are placed which is coated with magnetic material. These are connected with magnetic heads which are placed on the moving arm that helps to read and writing the data. This data is accessed through RAM which means the information which is present on the device can be opened without any proper sequence. It was first introduced in 1956 and has increased its space over the years. It has been produced by more than 150 companies over the years but the most famous ones are Seagate and Toshiba. The size of normal HDD is 3.5 inches for computers while the size for a laptop is around 2.5 inches. USB are the devices which have originated from the hard disks and gaining popularity.

Conclusion

Computer architecture is something that is a mystery for people who are general users and do not have a detailed knowledge of it. The two terms Hard disk and RAM are similar ones which are considered same but are different in the working and functions. This article, therefore, gives a proper understanding of the two types for people to get a clearer idea.
