Visual Binaries are rare compared to spectroscopic binaries because visual binaries have widely separated members bright enough to be observed and monitored separately.The orbital plane of the pair of stars in Eclipsing Binariesare almost edge-on to our line of sight. In this case we observe a periodic decrease of starlight intensity as one member of the binary passes in front of the other.Spectroscopic Binaries are too distant from us to be resolved into separate stars, but they can be indirectly perceived by monitoring the back-and-forth Doppler shifts of their spectral lines as the stars orbit one another and their line-of-sight velocities vary periodically.To summarize, Visual Binaries and Eclipsing Binariesare harder to identify and observe compared to the Spectroscopic Binaries, therefore Visual Binaries and Eclipsing Binaries are much more rare.McMillan, Chaisson , et. al.

The plural of binary is binaries. As in "he used binaries to write the code".
"Who invented original common Gateway interface binaries of PHP?"
There are many different Linux distributions, however most typically store system binaries in... /bin /sbin /usr/bin and system wide user contributed binaries in... /usr/local/bin and user specific binaries in... /home/YourLoginName/bin If I understand the question correctly.
I'm not sure what you are referring to by "structure." System binaries, like all other binaries in Linux, are in ELF class. The binaries are typically placed in /bin or /sbin. Almost all programs in Linux are POSIX-compliant.

Alt binaries is used by usenet and gather data from across the web to be used in data construction. They typsically gather gigabytes worth of information and process it for storage and distribution.
Binaries for free software can be downloaded from many sources on the internet. Such sources include HHD Software, Source Forge, GNU and Python. The software can be downloaded from the companies' respective websites.
They are pair of stars - hence binaries - which orbit one another. Strictly speaking, they orbit their centre of mass. Anyway, due to their motion each one will alternately eclipse the other - hence eclipsing.
