We have already covered virtual memory from a practical angle in <a href="https://outofsrvc.github.io/en/cworkshop/virtual-memory-stack-vs-heap/">the virtual memory lesson of the C workshop</a>; today&rsquo;s topic is <strong>cache memory</strong>.</p> <h2 id="cache-memory-overview">Cache Memory Overview</h2> <p><strong>Cache memory</strong> is a small, high-speed store usually located between the CPU and main memory (RAM). Its job is to hold copies of the most frequently used data and instructions so the processor can reach them quickly.</p>https://outofsrvc.github.io/en/arch/comp-arch-0x5/Tue, 25 Aug 2026 14:00:00 +0300https://outofsrvc.github.io/en/arch/comp-arch-0x5/<p>بسم الله</p> <p>After covering the cache in the <a href="../comp-arch-0x4/">previous article</a>, today we wrap up the memory topics so we come away with a clear understanding of memory in general — without descending into external memory, which benefits those working directly with hardware more than software people.</p> <h2 id="internal-memory">Internal Memory</h2> <p>Internal memory is also known as Main Memory:</p> <p>It represents the memory layers closest and fastest to the processor, used to store data and instructions currently being processed, distinguished by fast random access during operation. It includes the registers, cache, RAM, and ROM.</p>
