Final answer:
A burn-in test is a procedure performed on new computers to identify any problems or temperature-sensitive components. It involves operating the computer continuously for 48 to 72 hours to ensure stability and reliability.
Step-by-step explanation:
A burn-in test is a procedure commonly performed on new computers to identify any obvious problems or temperature-sensitive components. During the burn-in test, the computer is operated continuously for 48 to 72 hours to ensure its stability and reliability. This test helps to identify any issues that may arise under normal operating conditions and allows for necessary troubleshooting or repairs.
The purpose of the burn-in test is to push the computer to its limits and simulate real-world usage. It may involve running intensive tasks or applications that put a heavy load on the system. By subjecting the computer to prolonged operation, any potential hardware failures or thermal issues can be detected early on.
For example, if a computer has a faulty component such as a defective cooling fan, the burn-in test may trigger overheating, leading to system instability or shutdown. By identifying such problems during the burn-in test, manufacturers can ensure that the computer meets quality standards before it is shipped to customers.
