What is RAM? Everything We Know So Far

Laptop-RAM

RAM is now a very familiar word, and it stands for random access memory. It is a hardware device usually located on the motherboard of a computer and serves as the internal memory of the CPU.

All applications that we use on our mobile phones or PCs need to activate the memory.

All active tasks and applications need a temporary space to load into them so that the processor can quickly obtain the data required to run the application.

The CPU can directly access RAM to perform many tasks, and it is the computer’s main memory.

Reading or writing data in RAM is much faster than other types of storage (such as hard drives, solid-state drives, or optical drives).

Ram is very fast, with hard disk or SSD storage, you can even call it a hundred times master, it depends on some specific tasks and work.

The speed of memory collection of information is very fast, and it will automatically become temporary storage.

It is volatile, which means that when you connect a current in it, it will work, and then if you turn it off, it will come to the first stage.

What does RAM do and how does it work?

What does RAM do, and how does it work?

RAM is the short-term memory of our computer.

RAM saves temporary data when we perform work, and the same data can be accessed in random order, but sequential access is not possible.

It provides a working space for any application to run. Whenever we open an application on a mobile phone or PC, it will be loaded from the hard disk into RAM for easy and quick access to the data related to the application.

It can prevent loading data from the hard disk again and again, which is a time-consuming task.

In other words, RAM makes our system faster. It is Memory that allows multiple applications to run together without any delay. Without RAM, it is almost impossible to run a mobile phone or PC efficiently and smoothly.

Different Types of RAM

1. Static Random Access Memory (SRAM):

The short form of is static random access memory is SRAM, which is composed of memory cells. Multiple transistors are used to make each memory cell but do not have a capacitor in each cell.

This kind of memory requires continuous power to store data, which means, if there is no constant power, data preservation will be impossible.

SRAM is a volatile type, which means that your stored data will be lost with no current or power.

It is mainly used to make caches. Due to continuous power supply and no need for a regular refresh, it is called static RAM.

Advantage:

  • It has good data access speed.
  • SRAM is simple and easy to handle.
  • It is reliable, so it is used for caching.

Shortcoming:

  • It is a volatile memory, so all data will be lost once the power is turned off.
  • SRAM has a lower storage capacity and takes up more space.
  • It is more expensive than DRAM

2. Dynamic Random Access Memory (DRAM):

The Full form of DRAM is dynamic random access memory. It uses transistors and capacitors to create a memory cell that can represent one bit of data. Therefore, capacitors are used to store data or information in dynamic random access memory.

As we all know, capacitors tend to discharge even when powered on continuously; therefore, they begin losing the information within milliseconds, implying that they cannot keep information for an extended period even when powered on continuously.

As a result, it must be refreshed dynamically, known as dynamic random access memory. DRAM is also a volatile memory, which means that once the power is turned off, all recorded data is lost. This sort of memory is typically used to generate a huge amount of system RAM space.

Advantages:

  • DRAM is created using a basic approach that employs a single transistor.
  • It can store a large amount of data.
  • It necessitates a small amount of space.

Shortcoming:

  • Its accessing speed is much slower than that of SRAM.
  • Because it is volatile memory, all data is lost when the power is turned off.
  • It goes through a complicated production procedure.

How Much RAM Do I Need?

When buying a smartphone or laptop, everyone thinks about how much memory we really need to get the best performance.

Is not it?

Modern PCs usually have 2GB to 64GB of memory, but some have more. But how much money does a person need?

Having more RAM than the minimum is essential for performing every task. We must have at least the amount of RAM required to effectively run the operating system.

However, for users, this is not enough. A typical device should have at least the amount of RAM required to load a single program and at least one additional application program loading space.

However, how much RAM the user needs to achieve fast and seamless PC or mobile phone operation depends on the user.

In the background, the PC executes the current application and performs other services and tasks. However, having a lot of system memory does not always mean that the PC will run faster.

Multitasking requires a lot of RAM, such as 8GB, 16GB, or more. If the user is running multiple applications simultaneously, if the RAM is insufficient, he or she will not notice the good operation and smooth operation of the gadget. Because one application will be loaded, there will not be enough space to load another application side by side.

As a result, when the user switches to another program, the previously loaded application will no longer be active, and the user needs to reload the application to use it.

A PC with 4GB memory can perform basic operations and run basic software, but it may not run smoothly.

This RAM for a laptop is not enough to play modern games like Roblox, Fortnite, etc. At least 8GB of RAM is required for basic games, but this may not be enough to provide reasonable performance in intense games.

If any laptop has 16GB of memory, it can easily complete all of these tasks, from daily tasks to heavy tasks such as video editing, modern games, and AutoCAD.

Nowadays, 32GB of RAM is enough to provide a good and smooth gaming experience. All other reasonably sized applications will run smoothly, allowing you to enjoy the seamless operation of your computer.

PCs with higher RAM (64 GB and more) are also available, which can be used as needed.
