The front buffer is the image that is currently being displayed on the screen. The back buffer is the image that is being drawn to by a program. These switch back and forth, (moreover the information is transferred from the back to the front buffer), which lets the program draw exclusively to back buffer, where it will not be slowed down by the screen's refresh rate, as it would be if every element were drawn directly to the screen.

Buffering in OS?
It is a process of storing data in memory area called Buffers while data is being transferred between two devices or between a device and an application. Buffering is done for 3 reasons: a. To cope with the speed mismatch between producer (or sender) and consumer (or receiver) of a data stream. b. To adapt between the devices having different data-transfer size. c. To support copy semantics for application I/O.
What is a oc tcave?
If you mean "octave", it is a group of eight things. Most commonly it is used to describe the relationship between a musical tone and another which has half or double its frequency. The tone with half the frequency is an octave below and the one with double the frequency is an octave above. It's called an octave because it's the eighth note in a diatonic (major or minor) scale.
How can I convert a float to a double in Java?
To convert a float to a double in Java, you can simply assign the float value to a double variable. Java will automatically perform the conversion for you. Here's an example: java float floatValue 10.5f; double doubleValue floatValue; In this example, the float value 10.5f is assigned to the double variable doubleValue, which will now hold the converted double value.
What are some common scheduling problems that individuals or organizations face, and how can they be effectively addressed?
Common scheduling problems that individuals or organizations face include double booking, lack of communication, and unexpected changes. These issues can be effectively addressed by using scheduling tools and software, setting clear priorities and deadlines, and regularly communicating and updating schedules with all involved parties. Additionally, creating buffer time between appointments and being flexible can help accommodate unexpected changes and prevent scheduling conflicts.
How can I declare a double precision variable in Fortran?
To declare a double precision variable in Fortran, you can use the "real(kind8)" declaration. This specifies that the variable should be of double precision, which is typically 8 bytes in size.
What is indispensible?
1. Describe a specific characteristics of incoming data where simple buffering is sufficient to catch them without losing any part of it. Do the same for double buffering and circular buffering.
What gain is achieved by double buffering as opposed a single buffering?
Buffer is like bucket of data you write to at your own pace so that some other process can read from it at its own pace when it is needed. If you use a single buffer, you may end up overwriting what the other process did not read yet, or the other process may "catch up" with you before you finish writing your current set of data. Basically, you still need to carefully synchronize the two processes. With two buffers, you can write to one buffer while the other process is still reading the other buffer.
What is difference between single double and circular buffer?
single buffer : you read and write on the same buffer, can be messy if both reading and writing take place at the same time.double buffer : you read one buffer and you write the other one. When both reading and writing are complete, the buffers are swapped. It solves the problem of simultaneous reading and writing but requires synchronization.circular buffer : this a buffer with two pointer : read and write. If both pointers are equal, the buffer is empty.For each write operation, the write pointer advances and each time data is read back, the read pointer advances. It is circular because when a pointer reaches the end, it wraps back to the beginning.It may be used to implement a queue which allows simultaneous reading and writing without synchronization as long as the buffer is not full.A double buffer is basically a circular buffer of size 2 and a single buffer is basically a circular buffer of size 1.
