**Description:** The term ‘Unbuffered’ refers to a type of memory that operates without an intermediate storage area known as a buffer. In the context of microprocessors, this means that data is processed directly from the input source to the output, without the intervention of a buffer that temporarily stores the information. This feature can be crucial in environments where latency is a critical factor, such as high-performance servers. The absence of a buffer can result in faster processing, as delays associated with writing and reading data in a buffer are eliminated. However, it can also increase the risk of data loss if errors occur during transmission. Overall, ‘unbuffered’ architecture is used in applications where speed is a priority and where data integrity can be ensured through other means, such as robust communication protocols. This approach is especially relevant in various technological applications, including embedded systems and real-time applications, where every millisecond counts and efficiency is essential for overall system performance.
