Which memory device is generally made of semiconductors?Ĭlarification: Memory devices are usually made of semiconductors for faster manipulation of the contents.ĥ. A source program is usually in _Ĭlarification: The program written and before being compiled or assembled is called as a source program.Ĥ. The 8-bit encoding format used to store data in a computer is _Ĭlarification: The data to be stored in the computers have to be encoded in a particular way so as to provide secure processing of the data.ģ. The _ format is usually used to store data.Ĭlarification: The data usually used by computers have to be stored and represented in a particular format for ease of use.Ģ. According to Tech Target, "Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request.Computer Organization Assessment Questions on “Functional Units of a Computer”.ġ. It is also the closest to where the central processing occurs, being a part of the CPU itself. The CPU cache stands at the top of this hierarchy, being the fastest.
Lastly, the CPU has even faster memory units within itself, known as the CPU memory cache.Ĭomputer memory has a hierarchy based on its operational speed. Your computer and its programs use RAM to store frequently accessed data, helping keep actions on your computer nice and fast. This is much faster than the primary storage but is only a short-term storage medium. Next up, we have "random access memory," commonly known as RAM. Primary storage, like a hard disk or SSD, stores the bulk of the data-the operating system and programs.
Now, your computer has multiple types of memory inside it. The system memory at the time (RAM) couldn't cope with or match the increasing CPU speeds, so a new type of ultra-fast memory was born: CPU cache memory.
However, during the 1980s, processor speeds began to increase-rapidly. In the early days of computing, processor speed and memory speed were low. Put simply, a CPU memory cache is just a really fast type of memory.
So, exactly how important is CPU cache, and how does it work? What Is CPU Cache Memory?
