1 When a business chooses to hire a temp agency as a permanent employee, the business must pay the temp agency a permanent staffing fee ranging from 10-25% of the employee's first-year salary. Some large organizations have in-house temporary agencies which apply similar fees for their services. 2  For example, the University of Washington charges a 29% markup, with department's paying $18.06 per hour for a temporary employee who actually earns $14 per hour.
Interrupt chaning is a technique used to restore and call all of the interrupt handlers that share that same interrupt number. This is done by saving the previus Interrupt Routine (IR) in a function pointer. Then, installing the new handler, and calling the previus interrupt handler whenever the new IR is called.
What Is Relaying? If you've ever received unwanted spam in your mailbox, then you already know what relaying is: using a server to accept and then resend mail to recipients on another server. In the simplest case, alice@a.com connects to the SMTP server at b.com and uses it to deliver a message to charlie@c.com.
