What is Post and how it works?

When power is turned on, POST (Power-On Self-Test) is the diagnostic testing sequence that a computer’s basic input/output system (or “starting program”) runs to determine if the computer keyboard, random access memory, disk drives, and other hardware are working correctly.

What is the usage of POST error code?

If the POST code indicates that the last test has failed, we immediately know that the problem doesn’t lie with anything else; not the CMOS battery, video card, serial ports, CPU, etc., but instead with the system memory. At this point, you can narrow your troubleshooting to whatever is referenced.

Can we use post instead of get?

Essentially GET is used to retrieve remote data, and POST is used to insert/update remote data.

What is a post error?

A POST error message is an error message displayed on the monitor during the power-on self test if the BIOS encounters some kind of problem while starting the PC. A POST error message is sometimes called a BIOS error message, POST message, or POST screen message.

1) Intel currently has 242 publicly disclosed vulnerabilities, while AMD has only 16. That’s a 15:1 difference in AMD’s favor. The gap is just too large to ignore. 2) Less than half of the speculative execution side-channel attacks disclosed for Intel since early 2018 seem to affect AMD’s Ryzen and Epyc CPUs.

What is the lifespan of a motherboard?

Motherboard lifespan isn’t consistent. Sometimes it can go up to 7-10 years or even more than that and sometimes only 3-5 years. ASUS is well known to be a very good manufacturer of mobos. It would probably last longer than 4-5 years(you can’t actually state the exact lifespan of a mobo).

Can a PC last 10 years?

For most desktop PCs, you can expect a minimum three-year lifespan. However, most computers survive five to eight years, depending on the upgrading components. Owners should routinely upgrade software and keep the machines free from excessive dust and debris.
