RAM (Random Access Memory) is a type of computer memory that stores data temporarily, allowing the CPU (Central Processing Unit) to access it quickly. It acts as a workspace for your system, storing data and instructions for currently running applications and processes. The faster the RAM, the quicker your device can perform tasks, making it a crucial component in computing devices.

How Does RAM Work?
When you run a program or open a file, your computer loads the necessary data into RAM from the storage device (like an SSD or HDD). This is because accessing data from RAM is much faster than accessing it from storage. Once the program is closed, the data in RAM is cleared since RAM is volatile memory, meaning it loses its contents when the power is turned off.
Types of RAM
1. DRAM (Dynamic RAM)-
Dynamic RAM is the most common type of RAM used in computers and other electronic devices. It stores data in capacitors, which are tiny electronic components capable of holding electrical charges. However, these capacitors tend to lose their charge over time, meaning the data stored in DRAM needs to be refreshed periodically (typically every few milliseconds) to retain its integrity.

While this makes DRAM slower compared to other types of memory, its simplicity and cost-effectiveness make it the preferred choice for primary system memory in personal computers, laptops, and servers.
2. SRAM (Static RAM)-
Static RAM, or SRAM, is a type of memory that is faster and more reliable than DRAM. Unlike DRAM, SRAM does not rely on capacitors to store data. Instead, it uses flip-flops, which are circuits made up of multiple transistors that can hold their state as long as power is supplied. This eliminates the need for periodic refreshing, resulting in higher speed and lower latency.

However, the use of more transistors per memory cell makes SRAM more expensive and less dense compared to DRAM. Due to these characteristics, SRAM is typically used in smaller amounts for cache memory in CPUs and other high-performance applications where speed is critical.
3. SDRAM (Synchronous DRAM)-
Synchronous DRAM is an advanced version of DRAM that operates in synchronization with the system clock. This alignment allows SDRAM to coordinate its operations with the processor, improving efficiency and speed compared to traditional DRAM. SDRAM can execute multiple instructions simultaneously in a pipeline, further boosting its performance.
It is commonly used in modern computing devices, including desktops, laptops, and gaming consoles. SDRAM has served as the foundation for several advanced types of RAM, including DDR SDRAM.

4. DDR (Double Data Rate) SDRAM-
DDR SDRAM is an enhancement of SDRAM that significantly improves performance by transferring data twice per clock cycle—once on the rising edge and once on the falling edge of the clock signal. This effectively doubles the data transfer rate compared to standard SDRAM. Over the years, DDR has evolved through several generations, including DDR2, DDR3, DDR4, and the latest DDR5.

Each new generation has brought higher speeds, lower power consumption, and improved efficiency. DDR memory is widely used in a variety of applications, from personal computers to high-performance servers and gaming systems.
5. VRAM (Video RAM)-
Video RAM is a specialized type of memory designed specifically for graphics processing. It is used to store image and video data that the GPU (Graphics Processing Unit) needs to render visuals on a display. VRAM is optimized for high b
