c_e2d7svm0jjx0 | In multitasking operating systems, processes (running programs) need a way to create new processes, e.g. to run other programs. Fork and its variants are typically the only way of doing so in Unix-like systems. For a process to start the execution of a different program, it first forks to create a copy of itself. Then,... | Fork (system call) |
c_3l3znkea2nj6 | The fork operation creates a separate address space for the child. The child process has an exact copy of all the memory segments of the parent process.

c_tmgsro1h51hw | Instead, virtual memory pages in both processes may refer to the same pages of physical memory until one of them writes to such a page: then it is copied. This optimization is important in the common case where fork is used in conjunction with exec to execute a new program: typically, the child process performs only a ... | Fork (system call) |
c_0aax3v6qwshu | When a process calls fork, it is deemed the parent process and the newly created process is its child. After the fork, both processes not only run the same program, but they resume execution as though both had called the system call.

Usually, researchers would have a large number of measured variables, which are assumed to be related to a smaller numbe... | Exploratory Factor Analysis |
c_o1vofljir8q1 | Researchers must carefully consider the number of measured variables to include in the analysis. EFA procedures are more accurate when each factor is represented by multiple measured variables in the analysis. EFA is based on the common factor model. | Exploratory Factor Analysis |
c_r61lxivssv49 | In this model, manifest variables are expressed as a function of common factors, unique factors, and errors of measurement.
