Buffering in OS
1. What is the importance of Buffering in OS?
By using Buffering there are a bunch of things that can be achieved like overcoming speed differences between the devices and CPU. Also efficient usage of resources while data transfer is assured using this.
2. Can Buffering influence the performance of the system in any way?
Buffering is most advantageous with respect to system performance but in some cases like usage of excessive buffering or poor buffer management can lead to memory wastage and memory overhead. To make sure buffering influence the performance of the system in a positive way proper buffer size and efficient management are crucial.
3. How does Buffering manage the difference in speed between the Devices and the CPU?
As one of the functions of Buffering is to induce Asynchronous functioning, it helps the CPU and device independently. It does it by providing temporary intermediate storage for the data transfer. The Device can transfer the data in its own speed and the other hand CPU can retrieve the data at its own pace.
4. Does buffering improve operating system data reliability?
Buffering can improve data dependability, it offers chances for error management and recovery by momentarily storing data in buffers. Before being processed by the CPU, the data in the buffer can be retransmitted or repaired if mistakes happen during transmission.
Buffering in OS
In Operating Systems I/O operations are one of the most fundamental tasks that is needed to be carried out correctly and with the utmost efficiency. One of the techniques that we can use to ensure the utmost efficiency of the I/O Operations is Buffering. So, Buffering is a process in which the data is stored in a buffer or cache, which makes this stored data more accessible than the original source. Buffer is an area in memory that is used to hold the data that is being transmitted from one place to another and store the data temporarily.
There are a number of data storage devices that are used in a system, like Hard Disks, network devices, pen drives, etc. So, there might be some waiting time faced by the processes or applications that are attempting to access that data from the storage devices. This problem is mainly caused when the devices from where device is slow or have low latency.
This problem is significantly solved using Buffering, as in this process the buffer acts as an intermediate between the storage device and the processes/applications. In this process, the data is already transferred to the Buffer so the data retrieval can be done from it which significantly reduces the waiting time and hence improves the performance of the system.
