Random Access Memory: RAM
RAM is also known as Main Memory, Internal Memory, Primary Storage, Primary Memory.
RAM can access data in a random order, so finding a particular information part makes it very fast.
While other types of storage do not have random access to data For example, in a hard disk drive and the CD the data is read and written in a predetermined order. The mechanical design of these devices determines that data access is fast. This means that the time it takes to get specific information depends on where it is located on the disc.
RAM is used as the main memory in the computer system. RAM is known as volatile memory, which means that all information stored in the RAM is destroyed when the computer turns off.
Therefore, RAM is in control of the Central Processing Unit (CPU). When a computer runs to store information, it needs to be used very quickly, but it does not store any information permanently.
Current-day RAM uses integrated circuits to store device information. It is a relatively expensive type of storage and the cost of storage is much higher than the units per unit hard drive.
However, the time to access RAM data is so fast that due to this the cost of RAM has increased. Therefore, computers, fast-access, temporary storage of information and hard disk drives, like Permanent Storage uses a certain amount of RAM.
Some popular types of RAM include Kingston, Transcend, Hynix, Samsung, Lenovo, HP, etc.
Your Computer Needs RAM to Quickly Access Data | All About RAM
To understand simple language, RAM aims to provide quick read and write access to a storage device. Your computer uses RAM to load data because it is too fast to run the same data directly from a hard drive.
Think of it with an example, you are sitting at your office desk and kept the documents, pens, calculators and other items on your desk so that you can get them quickly.
If you do not keep these items on your desk, you will keep everything in your place such as the files in the cabinet, in the drawer of the write-up, you will take more time to access them.
Which means that it will take more time to complete your everyday tasks, because you need to constantly reach these storage cartons, and you have to spend extra time.
Similarly, all the data actively used on your computer (or smartphone, tablet, etc.) is stored in temporary RAM.
In this way, RAM is like a desk, which provides faster read/write time than a hard drive. Due to physical limitations like rotation speed, most hard drives are significantly slower than RAM.
History of RAM | All About RAM
RAM was first used in computers in the 1940s. Magnetic-core memory was dependent on the magnetic ring’s array. Where Magnetizing Rings helps in storing the data. There was a bit of data store in each ring and magnetization indicates zero or forest direction.
As a result of technological progress, small devices came into existence which could store more information but could have believed in the same principle.
The real success for computer memory came from the invention of solid-state memory in the integrated circuit in the 1970s. The Solid-State Memory made use of small transistors, making it possible to store a lot of information in this very small area. However, this increase in memory density was at the expense of volatility: we require a constant power supply to maintain the status of each transistor.
In the early 1990s, clock speed was synchronized with Random Access Memory.
SDRAM reached its limit early because it transfers it to a single data rate.
Around the year 2000, the Double Data Rate Random Access Memory (DDR RAM) came into existence. It could transfer twice the data to a clock cycle. The introduction of DDR RAM has also changed the definition of SDRAM because many sources now define it as a single data rate ram.
The DDR RAM has developed three times, through DDR2, DDR3, and DDR4. Speed and low power consumption of data improved in each iteration. However, each version is not compatible with the previous ones.
How Much RAM Do You Require?
Just how much RAM you require for your PC just like a CPU and hard drive, it depends entirely on your usage.
For example, if you’re buying a computer for large gaming, you’ll need enough RAM to support smoother gameplay. At least 4 GB of a game that recommends only 2GB of RAM, the game will give a very slow performance, or you will be completely unable to play the game.
FAQs About Ram
What is the RAM in a computer?
RAM is a internal memory of a computer. When any task preform by us in the computer all the data is storged in RAM but it is not a permanent storage.
What are the 3 types of RAM?
In this latest generation there are three type of RAMs is released in the market DDR2, DDR3, DDR4.
Where is RAM located?
RAM is located in the motherboard of any computer. All the latest computer supports multiple RAMs to boost the performance of the computer.
