RAM (Random Access Memory)

RAM is a type of computer memory that can be accessed randomly, meaning that any byte of memory can be accessed without having to access the previous bytes first. RAM is much faster than other types of computer memory, such as hard disk drives.

RAM is an important part of any computer because it allows the computer to access data quickly. Without RAM, a computer would be much slower.

There are different types of RAM, such as DRAM and SRAM. DRAM is the most common type of RAM, and it is used in most computers. SRAM is slower than DRAM, but it is often used in devices that require high speed, such as video cards. RAM is a type of data storage used in computers that allows for quick access to information. The speed of access is determined by the time it takes for the system to find the requested data.

RAM is used to store data that is currently being used by the CPU (Central Processing Unit). When the CPU needs data, it requests it from RAM. The time it takes for the CPU to receive the data is called latency.

RAM is classified as either volatile or non-volatile. Volatile RAM requires power to retain data, while non-volatile RAM does not. The most common type of RAM is DRAM (Dynamic RAM), which is a type of volatile RAM.

Latency is important for applications that require quick access to data, such as video games. The faster the RAM, the lower the latency, and the smoother the game will run.

There are two main types of RAM, SRAM (Static RAM) and DRAM (Dynamic RAM). SRAM is faster than DRAM, but it is also more expensive. DRAM is slower than SRAM, but it is cheaper.

The type of RAM you choose for your computer depends on your budget and your needs. If you need the fastest possible speeds, then you should choose SRAM. If you are on a budget, then you should choose DRAM.

Now we understand how RAM works, now upgrading the RAM makes sense. 

How to upgrade the RAM in the iMac?

Aside from the obvious sales benefits for RAM manufacturers, there are a few reasons why you might want to upgrade your iMac's RAM. More RAM can help your computer run more smoothly, particularly if you're running resource-intensive applications or working with large files.
