A poll message is a control-acknowledgment message..

Microsoft Windows 95 and Windows 98 (First and Second Editions) set the refresh rate to the highest rate that they believe the display supports. Windows NT -based operating systems, such as Windows 2000 and its descendants Windows XP , Windows Vista and Windows 7 , set the default refresh rate to a conservative rate, usually 60 Hz.

For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
Because the desired transfer speeds were faster even than could tolerate the minimum four-operation per-datum loop (bit-test, conditional-branch-to-self, fetch, and store), the hardware would often be built with automatic wait state generation on the I/O device, pushing the data ready poll out of software and onto the processor's fetch or store ...
The ability to embed Java applets into browsers (starting with Netscape Navigator 2.0 in March 1996 [11]) made two-way sustained communications possible, using a raw TCP socket [12] to communicate between the browser and the server. This socket can remain open as long as the browser is at the document hosting the applet.
epoll is a Linux kernel system call for a scalable I/O event notification mechanism, first introduced in version 2.5.45 of the Linux kernel. [1] Its function is to monitor multiple file descriptors to see whether I/O is possible on any of them.
