CompTIA Review Questions

1. When a technician upgrades firmware on a motherboard he has to_______?

Flash the bios

Replace the CMOS chip

Replace the Bios

Reset the CMOS

CMOS is a memory chip that is designed to draw very little current. This memory is used to contain system configuration settings, BIOS passwords and time and date. Bios is the Basic Input/Output System that could be referred to as the motherboards firmware. Bios is contained on a chip that usually is soldered to the motherboard and should not be replaced. Flashing a Bios is the term used when upgrading the program (firmware) on the Bios Chip

Use extreme care when updating bios, any disruption of power or reset during flashing or upload will render the computer useless.

Worms, which most commonly install a "backdoor" internet connection on the host computer, are perfect for sending out the millions of server requests needed to achieve a denial-of-service attack. A denial-of-service attack is when a server is maliciously sent so many hits that it is overwhelmed and cannot continue to operate.

95. Which of the following can be used for connecting a mouse to the computer? (choose all that apply)

6-pin mini-din connector

Din-5 connector

Db-9 to db-25 pin adapter

Din-9 connector

A 6-pin mini-din connector is more commonly known as a ps/2 connector. PS/2 mouse interface is a type of mouse interface that uses a round din-6 connector that gets its name from the first computer it was introduced on, the IBM ps/2.

All computers came with at least one serial port that the mouse could use with its female db-9 connector. If the port was of the 25-pin variety, the user could plug the mouses's db-9 connector into the adapter that was usually included with the mouse to allow it to work.

A din-9 connector plug is used to connect to a bus mouse port.
