Random Access Memory (RAM)

When you switch on your computer or open an application, you’re using a key component inside your device known as RAM — short for Random Access Memory. Even if you’re not tech-savvy, understanding RAM will help you make smarter choices when buying or upgrading your computer or laptop.

What is Random Access Memory?

Random Access Memory (RAM) is a type of temporary memory used by computers to store data that is currently being used or processed. Unlike a hard drive or SSD, RAM is volatile memory — meaning it only works while the computer is turned on. When you shut down the computer, the data in RAM is erased.

Think of RAM as your computer’s short-term memory. It helps your system run programs and access data quickly so you can work efficiently.

• RAM stores data temporarily for quick access.
• It is faster than hard drives and SSDs.
• More RAM allows you to run more applications at once.
• Data in RAM is lost when the computer shuts down.

When you open an application like a web browser or a game, your computer loads that program’s data from the hard drive into RAM. This is because accessing RAM is much faster than accessing the hard drive. The processor then uses this data from RAM to perform tasks.

The more RAM you have, the more data your computer can access quickly — which means better multitasking and smoother performance.

 

Types of RAM Memory

Types of RAM are as follows:

• DRAM (Dynamic RAM)
• SRAM (Static RAM)
• SDRAM (Synchronous DRAM)
• DDR RAM (Double Data Rate RAM)
• DDR2, DDR3, DDR4, DDR5 RAM (Improved versions of DDR RAM)

RAM Slots

RAM slots are physical connectors on the motherboard where the RAM sticks (modules) are inserted. Most desktops and laptops have two or more RAM slots. These slots allow you to add more RAM modules to increase your system’s memory capacity.

Each slot supports a specific type and speed of RAM, so you must install compatible RAM modules.

RAM Chip on the Motherboard

A RAM chip is a rectangular circuit board with memory cells that store data. These chips are mounted on RAM modules, which are then inserted into the RAM slots on the motherboard. Some older computers may have RAM chips soldered directly onto the motherboard, but most modern PCs use removable RAM sticks.

RAM Slots

A RAM slot is a connector on the motherboard that holds a RAM module. Expandable RAM slot means your system has extra slots available where you can insert additional RAM modules to increase the total memory capacity.

For example, if your computer has two RAM slots and only one is used, the other one is available for future expansion — making your system upgrade-friendly.

RAM Size

You can find the RAM size on a Windows computer using System settings screen.

• Press Windows + I to open Settings.
• Go to System → About.
• Look for Installed RAM under Device specifications.
