A buffer, or data buffer, is an area of physical memory storage used to temporarily store data while it is being moved from one place to another. These buffers typically live in RAM memory. Computers frequently
Buffering is the practice of preloading and storing a portion of a media file in the buffer or temporary memory of a device. This process enables video, audio, gaming, or other media files to be played smoothly and without jitter or stuttering. Having an advanced supply of video frames, ...
can exploit buffer overflow vulnerabilities to damage objects, including ARG (actual parameter when the function is called), RETADDR (address of the next operation instruction in the memory), EBP (stack frame status value before the function is called), and LOCVAR (local variable in this ...
Contrary to popular belief, implementing flash or more DRAM on a system won't increase cache memory. This can be confusing since the termsmemory caching(hard disk buffering) andcache memoryare often used interchangeably. Memory caching, using DRAM or flash to buffer disk reads, is meant to imp...

In computers, a buffer acts as a chamber, or holding area, for memory. The buffer is usually in the random access memory (RAM), and allows the central processing unit (CPU) to manipulate data before sending them to another device. One side of the buffer fills the chamber while the other...
The term disk cache can also refer to a disk buffer and cache buffer. The basic idea behind a disk cache is that working with information stored in memory (RAM) is much faster than working with information stored on disk. A disk cache is a software utility that works by reserving a ...
One real-life example of a buffer overflow attack is the 1988 Morris Worm. The Morris Worm was acomputer wormthat exploited a buffer overflow vulnerability in Unix programs. The worm infected over 60,000 computers worldwide, causing an estimated $10 billion in damages. ...
worm-- that quickly spread through the internet and triggered buffer overflows and DoS attacks on the affected systems. Those connected to the internet at the time were mostly research and academic institutions, but it was estimated that as many as 10% of the 60,000 systems in the U.S. ...
In older machines with slow CPU and RAM, it is possible for the user to type faster than the buffer can store the data, so an error is returned that the keyboard buffer is full. In this case, the user must simply type slower. However, this is no longer a problem in modern computers...
