It is often important that these messages can be viewed later, even much later, so they should be written to a file.
If a program fails, it may cause memory used by one or more other programs to be affected or overwritten. The operating system is also a set of services which simplify development and execution of application programs.
The same applies for Glary Utilities, but only for the professional edition. As a switched Ethernet connection is full-duplex, inbound and outbound network traffic need to be sized independently.
