Why could be the deletion ungrammatical in "I similar to the Female [who's] the prettiest in my class" but grammatical in other sentences?

And components resources at any stage even during application execution consequently connect with program calls which simply call I/O routines coded in assembly language.

The main one matches only one whitespace, While the second one matches 1 or numerous whitespaces. They're the so-referred to as typical expression quantifiers, and they perform matches similar to this (taken with the documentation):

All device dependent code is composed in assembly language.The assembly language differs for various processors.

Its for the reason that device dependent stuff and early initialization such as starting cache and memory can only be performed with assembly degree instructions which include I/O Recommendations.
