C. Explanation of RAM

RAM stands for Random Access Memory and is a type of computer memory used to store data and program instructions currently being used by the processor. RAM is considered volatile memory. This means that saved data will be lost when the computer is turned off or restarted. The function of RAM is to give the processor quick access to the data and program instructions it needs to perform its tasks. When a user launches an application or performs a task, the necessary data and instructions are loaded into RAM so that the processor can quickly access and execute them. This will improve the overall speed and responsiveness of your computer. RAM works by storing data in memory cells that the processor can quickly access. The cells are organized into memory modules that plug into memory slots in your computer. The processor can access data stored in RAM in any order, making it much faster than other storage types such as hard disk drives (HDD) and solid state drives (SSD). The processor and RAM communicate through a memory bus that transfers data between the processor and RAM.

II. History of RAM

RAM's history dates back to the 1950s, when scientists began experimenting with magnetic core memory. This was he one of the earliest forms of computer memory. Magnetic core memory used a small ring of magnets to store data, but it was expensive and took up a lot of physical space. In the 1960s, a new type of memory was introduced called transistor-transistor logic (TTL) dynamic random access memory (DRAM). It was more compact and cheaper than magnetic core memory. TTL DRAM was followed by the more compact and energy efficient MOS (Metal Oxide Semiconductor) DRAM. During the 1970s and 1980s, DRAM continued to evolve, with the introduction of fast page mode DRAM and extended data output (EDO) DRAM, increasing memory access speeds. In the late 1990s, synchronous dynamic random access memory (SDRAM) was introduced. SDRAM synchronized the memory clock with the processor clock, further improving memory performance. In recent years, new types of RAM such as DDR (Double Data Rate) SDRAM, DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM, and DDR5 SDRAM have been introduced with faster speeds and improved performance.
