Cybersecurity- A+ 220-1101 (Chapter 1)

CMOS (CMOS RAM chip maintains startup configuration using a small 3.3-volt battery, the BIOS stores the information.)

Which of the following is responsible for retaining system startup settings when the computer is powered down?

AC (AC stands for alternating current which means the current alternates b/w positive and negative peaks constantly instead of staying at the same voltage level)

Which of the following types of electricity represents current that fluctuates constantly b/w positive and negative endpoints?

What is something that is not required by hardware in the PC in order to function?

You do not need direct connection to the hard drives for a component to work in the PC.

A method to communicate with the CPU & Software to control the device (devices utilize CPU in order to process data & access information. It also requires a device driver for the operating system to control the device)

Every hardware device requires which 2 things in order to communicate and function inside a personal computer-

Input (used to send data to the computer for processing such as mouse clicks and keystrokes)

If a device is used to send information to the computer like a mouse or a keyboard, what type of device is it?

CPU & Motherboard Bus

What 2 components provides direct connection to the hard drives for a component in the PC

Expansion Card (You can expand upon the capabilities of the personal computer, adding additional devices through the use of expansion cards & buses.)

Which of the following allows users to add devices that do not come with a standard PC package?

Motherboard (large circuit that provides communication b/w various components like CPU, Memory, storage devices, etc.)

Which of the following circuit board in a personal computer that provides sockets (connections) & communication lines for all PC components?

CPU (the brains of the computer and handles all activities between the various devices and software)

Which of the following components control all activities within the personal computer?

RAM (Primary storage for applications that are currently running while hard drives provide permanent storage.)

Which of the following devices or components, called primary storage, is responsible for holding application and systems while the computer is powered on?
