Today, we will discuss about the RAM. We all know RAM, it's installed on our phones, laptops, pcs, desktops, etc. But do we really know how actually a RAM works and whats its role in our electronic devices and why do we need a RAM? Well TECHNO HUB will give answers to all your questions regarding a RAM.

What is RAM?

style="background-color: white; color: #202122; font-size: 14px; margin-bottom: 0.5em; margin-top: 0.5em;"> Random-access memory (RAM /ræm/) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code.[1][2] A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. In contrast, with other direct-access data storage media such as hard disks, CD-RWs, DVD-RWs, and the older magnetic tapes and drum memory, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.
RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually, more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. devices.

In other words, A RAM is something that is used to read, write, and store data ( working data ). Suppose you are working on your phone or desktop. The role of a RAM is to store your data on which you are working so that you can continue your work.
Like you are playing the game on your phone, the RAM stores the data to the game so that there are no interruptions in the game and runs smoothly. Generally, RAM is a short term memory, it stores the memory only for a specific period of time and when you close the application it deletes all your data.

How does RAM works?

Again here it's the same that we have discussed above. Let's discuss it in another way and take a general example.
Suppose you are working in an office and you are doing some kind of work. For that work, you'll need a specific file, and that file is in another room. To complete that work you will go to that room take that file and start doing your work. Similarly, when you have to do more work at the same time you'll need multiple files and more space and you will apply the same process. After the completion of the work, you put all the files in the same place from where you took it.
The RAM also works like this. The other room where your files were stored is INTERNAL MEMORY. And the file you are looking for is the DATA of the application, which is stored in your internal memory. When you start or runs an application or program, your phone sends a request to the RAM to take the necessary data from your internal storage regarding that application/program and store it temporality on your RAM. When you close that program the RAM removes that DATA from the storage and puts back to its place i.e. INTERNAL MEMORY.
By the above explanation it is clear that if you are doing multitasking i.e. doing more than one task at the same time, you'll need more RAM memory and more INTERNAL MEMORY. So this is the way how your RAM works.

Difference between RAM and ROM :

Below is the comparison chart that will explain the basic differences between RAM and ROM.
SOURCE: GOOGLE
BASIS FOR COMPARISONRAMROM
BasicIt is a random access memory.It is a read-only memory.
UseUsed to store the data that has to be currently processed by CPU temporarily.It stores the instructions required during the bootstrap of the computer.
VolatilityIt is a volatile memory.It is a nonvolatile memory.
Stands forRandom Access Memory.Read-Only Memory.
ModificationData in RAM can be modified.Data in ROM can not be modified.
CapacityRAM sizes from 64 MB to 4GB.ROM is comparatively smaller than RAM.
CostRAM is a costlier memory.ROM is comparatively cheaper than RAM.
TypeTypes of RAM are static RAM and dynamic RAM.Types of ROM are PROM, EPROM, EEPROM.


Some TIPS to make your ROM faster :

For SMARTPHONES :

1) Disable screen animations or increase their speed which will give less impact on your ROM and make your android faster.
2) Uninstall all unused and rarely used apps so that it can clear up your internal memory and will make your android faster.
3) Don't use any cleansing RAM applications. This removes all the cache and data from your RAM which will slower your android.

4) Always clear your RAM manually after the work ( Don't clear your cache ).
5) Always reboot your phone after a certain period of time (let's say after every one week ).
6) Try to keep your phone storage as free as possible.
7) Keep updating your android versions or security updates that the smartphone company provides you.
8) If you RAM is of less GB then don't do much multitasking.

For Windows PC/DESKTOP :

1) Remove all unwanted and unused software from your windows.
2) Always use antivirus software for windows.
3) Always use and keep turn on the WINDOWS DEFENDER and WINDOWS FIREWALL.
4) Stay safe and keep your windows safe from malicious software they can slow down your pc and RAM.

5) Upgrade your RAM or try to keep your internal storage free as much as possible.
     To do this :
     Open RUN ( WIN + R )
     Type TEMP and hit ENTER. Then select all the folders and permanently delete them all. 
     Similarly, type %TEMP% and PREFETCH and follow the same steps.
     Then type CLEANMGR and delete all your temporary files.
6) Upgrade your SSD and try to use only those software that is compatible with your PC.
