What Is RAM & How does it work?

Anyone who uses their own computer as a PC geek may be really curious about what RAM is. It is an essential component of a computer system. The application software, operating system, and data that are now in use are stored in Random Access Memory-RAM. This allows the computer’s processor to temporarily access them as needed. The other types of storage inside a computer system are nothing compared to RAM. Even faster than a hard drive, CD-ROM, or a floppy disk. Only when a computer is running can information that is kept in RAM be accessed. When a computer is turned off, data previously kept in RAM is lost.RAM - Random Access Memory

When the computer is restarted, data from the hard drive is retrieved to bring RAM back into focus. RAM is similar to main memory in that it may be accessed by programs.

RAM – Random Access Memory – How does it work?

RAM works quite similarly to short-term memory in humans. RAM can access the computer’s long-term memory to retrieve data, much like the human brain can. When short-term memory is exhausted, this is frequently necessary. Most computers have a hard drive that can store 40 billion bytes in addition to at least 256 million RAM bytes. Data is stored on a record-like magnetized surface.
Without accessing the other bytes, each byte of RAM can be determined independently.
RAM comes in two variations. SRAM stands for static random access memory, while DRAM stands for dynamic random access memory. The more widely known of the two is DRAM. DRAM needs to be refreshed at a rate of several thousand times per second. Information access in DRAM takes 60 nanoseconds. SRAM is more expensive but performs at a significantly faster rate than DRAM. A memory cell is created when a transistor and a capacitor interact. This is a single piece of data. Additionally, SRAM permits access in as little as 10 nanoseconds at times.

RAM has been around for many years and has changed over time. DDR-RAM is currently the most widely used type of computer memory (Double Data Rate Random Access Memory). With each successive DDR RAM generation, some advancements are made. For instance, DDR5 uses less power than DDR4, giving mobile devices longer battery life. Additionally, the newest memory is twice as quick as DDR4.

Your motherboard must be compatible with the type of memory you buy. To obtain the details, speak with the maker of your motherboard. The most recent RAM will not function with a motherboard from a previous generation, like any other technological advancement.

This is a brief definition of how RAM works in a computer system.
