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 a post PC stage?
The Post-PC era is a market trend observed during the late 2000s and early 2010s involving a decline in the sales of personal computers (PCs) in favor of post-PC devices; which include mobile devices such as smartphones and tablet computers as well as other mobile computers such as wearable and ubiquitous ones.
Are we in a post PC era?
The use of mobile devices rather than only desktop computers for games, Internet access, general computing and as a terminal to the corporate network. We are in the post-PC era today. The Web standards were the catalyst for the post-PC era.
What is the difference between POST and BIOS?
The BIOS is firmware which contains information for hardware, operating systems and drivers to interface with the motherboard components. It stores information concerning what hardware is available. The POST is the Power On Self Test which the BIOS runs when you power on the computer.
What is Post motherboard?
POST is an acronym for Power On Self Test. Basically it’s a process the motherboard goes through to make sure all components are working as expected before attempting to load the OS.
WHO stated that in 2012 computing was moving into a phase he called the post PC world?
Ray Ozzie
Ray Ozzie, a technology visionary at Microsoft, stated in 2012 that computing was moving into a phase he called the post-PC world. Now six years later that prediction has not stood up very well to reality.
What is BIOS stand for?
BIOS, in full Basic Input/Output System, computer program that is typically stored in EPROM and used by the CPU to perform start-up procedures when the computer is turned on.
Why the personal computer is now considered a commodity?
The Commoditization of the Personal Computer
The PC has become a commodity in the sense that there is very little differentiation between computers, and the primary factor that controls their sale is their price. Hundreds of manufacturers all over the world now create parts for personal computers.
What is the mainframe era?
THE MAINFRAME ERA
From the late 1950s through the 1960s, computers were seen as a way to more efficiently do calculations. These first business computers were room-sized monsters, with several refrigerator-sized machines linked together.Nicknamed “Big Blue,” the company became synonymous with business computing.
What is the difference between BIOS and bootloader?
Originally Answered: What is the difference between a BIOS and a boot loader? BIOS is generally made by the Hardware manufacturer and Loads the Boot loader into memory. Boot Loader comes with a operating system. Once Boot Loader is in the RAM, It loads the whole Operating System like windows for a user.
What should come first the POST or the BIOS Why?
During this process, you might hear the whirring sound of the hard drive. This process is known as the power-on self-test (POST). So, BIOS comes first. This BIOS is a thing and POST is an action.
Is CMOS a RAM?
1. Alternatively referred to as a RTC (real-time clock), NVRAM (non-volatile RAM) or CMOS RAM, CMOS is short for complementary metal-oxide semiconductor. CMOS is an onboard, battery powered semiconductor chip inside computers that stores information.
Do you need an OS to POST?
POST doesn’t rely on any specific operating system. In fact, there doesn’t even need to be an OS installed on a hard drive for the POST to run. This is because the test is handled by the system’s BIOS, not any installed software.The computer will continue to boot after the POST, but only if it was successful.
What is needed for PC to POST?
Well youd need a stick of memory at least as well, and a cooler on the cpu. And a monitor to see it had posted, along with a video card of course unless the mobo has integrated.
What is the full form of POST?
POST stands for Power On Self Test. It is a series of computer checks run by the computer and its engine when the computer is turned on.
What are 3 examples of information system hardware?
Computers, tablets, mobile phones, disk drives, and more are all examples of information system hardware.
How did computers affect the history?
Computers have evolved and advanced significantly over the decades since they originated. Gradually, computers have become smaller and faster, enabling people to use them virtually anywhere.New computer technology has enabled more advanced business tasks as well.
What are computer hardwares?
Quite simply, computer hardware is the physical components that a computer system requires to function. It encompasses everything with a circuit board that operates within a PC or laptop; including the motherboard, graphics card, CPU (Central Processing Unit), ventilation fans, webcam, power supply, and so on.
What does post stand for in it?
Stands for “Power On Self Test.” POST (or P.O.S.T.) is a series of system checks run by computers and other electronic devices when they are turned on.
What is the purpose of Lojack?
It allows the owner of a device to remotely locate, lock, or delete all files from the device. It ensures that a computer will only boot an operating system that is trusted by the motherboard manufacturer.
How do BIOS work?
How does BIOS work? BIOS comes included with computers, as firmware on a chip on the motherboard.After testing and ensuring boot devices are functioning, BIOS loads the OS — or key parts of it — into the computer’s random access memory (RAM) from a hard disk or diskette drive (the boot device).
