What is the need of reading buffer from indicators?

<p id="isPasted">Buffer</p><ul><li>A buffer is a temporary storage area in memory used to hold data while it is being transferred from one place to another. It acts as an intermediary between two processes or devices that may operate at different speeds or have different data transfer rates.</li><li>Buffers are commonly used in various scenarios, including I/O operations (e.g., reading from or writing to a file), network communication (e.g., sending or receiving data over a network), and data processing (e.g., data transformation or manipulation).</li><li>The primary purpose of a buffer is to smooth out the differences in data transfer rates between the source and the destination, ensuring a steady flow of data and preventing data loss or corruption.</li><li>Buffers are typically implemented as fixed-size memory regions, and data is written to or read from the buffer in manageable chunks. When the buffer is full, data is transferred to its destination, and when it’s empty, it is refilled from the source.</li><li>Buffers are crucial for data integrity and efficient data transfer, especially in situations where data flows are not synchronized.</li></ul><p><br></p><p id="isPasted">In this scenario, a buffer is used to read data from a file into memory and then write it to another file. This process helps smooth out the differences in data transfer rates between the file and memory.</p><p><br></p>
