Also known as a BIOS setup utility, a CMOS setup utility is software that edits settings for hardware in a computer's BIOS. In earlier models, users had to alter settings each time they added a new drive, but the addition of auto-detect features made this unnecessary. While technical support is sometimes still necessary to make an adjustment, users still have to make changes sometimes, such as the computer's boot order.Know More
Even though this utility controls BIOS setup, the reason why it is sometimes called CMOS setup utility or CMOS RAM is because, originally, these settings dwelt in a CMOS memory circuit with battery backup. As technology advanced, BIOS setting moved for storage into flash memory that was not volatile.
Every time a computer starts up, it accesses the BIOS setup. Right after the user turns on the computer, a quick message appears (and then just as quickly disappears) asking the user to press a particular key, such as F1, F2, DEL or ESC, if the user wants to go to a different startup, other than the normal one, in order to make changes to the BIOS setup. If the user fails to hit that key in time, the computer proceeds to start normally.Learn more about Computer Programming
Computer hacking describes the modification of a computer's hardware or software to accomplish a specific goal that does not align with the owner's original purpose. Computer hackers typically have expert-level knowledge in the area of computer technology, which gives them very deep insight into how computers work and the skills necessary to manipulate them in a variety of ways.Full Answer >

The primary advantage of including a GUI with software is that it makes it easier for the vast majority of users to learn and use the application. The main disadvantages are that it uses more system resources, thus degrading the overall performance of the software. Additionally, GUIs often provide the user with less granular control over the operations.Full Answer >
