45
Q

We store all of our computer’s data on what?

A

hard drive

46
Q

what allows us to store our programs, music, pictures, etc.

A

hard drive

47
Q

what are the two basic hard drive types used today?

A

HDDs & SSDs

48
Q

what does HDD stand for?

A

Hard Disk Drive

49
Q

What does SSD stand for?

A

Solid State Drive

50
Q

what uses a spinning platter and a mechanical arm to read and write information?

A

Hard Disk Drives, HDDs

51
Q

The speed of the HDD, that the platter rotates allows you to what? .

A

read and write data faster

52
Q

The speed of the HDD that the platter rotates allows you to read and write data faster. This is commonly referred to as what?

A

RPM, or revolution per minute.

53
Q

What does RPM stand for?

A

Revolution per minute

54
Q

A hard drive with a higher RPM is what?

A

Faster

55
Q

HDDs are prone to a lot more damage because of what?

A

there are a lot of moving parts

56
Q

The HDDs susceptibility to damage went away with a new type of storage called what?

A

SSD

57
Q

Out of HDDs & SSDs which one has no moving parts?

A

SSDs

58
Q

How are SSDs created in a similar way as USB sticks?

A

information is stored on microchips & data travels faster than HDDs

59
Q

The form factor for SSDs is slimmer compared to what?

A

HDD

60
Q

what are the pros & cons of HDDs & SSDs?

A

HDDs are more affordable, but more prone to damage.

SSDs are less risky at losing data, but also more expensive.

So you may not buy as much memory storage in SSDs than what you can get in HDDs.

61
Q

the hybrid of SSD and HDD is known as what?

A

solid state hybrid drive, SSHD

62
Q

what is an example of a hybrid hard drive?

A

SSHD

63
Q

An SSHD is a device that is designed to do what?

A

combine flash memory storage and HDD storage into a single device

64
Q

What do SSHDs have built in them?

A

solid-state storage built in but also use HDD technology as a way to provide additional storage space.

65
Q

What does SSHD stand for?

A

solid-state hybrid drive

66
Q

what is the most common interface that hard drives use

A

ATA

67
Q

what is the most popular ATA drive?

A

SATA, Serial Advanced Technology Attachment

68
Q

how are programs & software different ?

A

A program is a piece of code or a set of instructions that performs a given task

a software is a set of programs used to perform a task, which is more complex than that of a program.

Software is more complex and more essential than that of a program.

A computer doesn’t work without a software

69
Q

What are the two types of electricity?

A

DC & AC

70
Q

What’s the difference between DC & AC electricity?

A

DC, Direct Current flows in one direction

AC, Alternating Current changes direction constantly

71
Q

What does the power supply do?

A

It converts the AC we get from the wall into low voltage DC power that we can use and transmit throughout our computer.

72
Q

What kind of voltage do our computers use?

A

DC voltage

73
Q

what is a charge cycle?

A

one full charge and discharge of a battery

74
Q

our devices use programs to tell the CPU how to run them.
These programs are called what?

A

services or drivers

75
Q

The drivers contain the instructions our CPU needs to understand what?

A

external devices like keyboards, webcams, printers.

76
Q

Our CPU doesn’t know that there is a device that it can talk to, so it has to connect to something called the what?

A

BIOS, or basic input output services.

77
Q

what is the BIOS?

A

software that helps initialize the hardware in our computer and gets our operating system up and running

78
Q

Where is the BIOS firmware stored?

A

Originally, stored in a ROM chip on the PC motherboard

In later computer systems, the BIOS contents are stored on flash memory

so it can be rewritten without removing the chip from the motherboard.

79
Q

The BIOS isn’t stored on a hard drive. Our motherboard stores the BIOS in what?

A

a special type of memory called, the read-only memory chip, or ROM chip.

80
Q

Unlike RAM, ROM is what?

A

non-volatile

81
Q

In today’s system, there is another player for BIOS called UEFI, which stands for what?

A

Unified Extensible Firmware Interface.

82
Q

UEFI performs the same function of what?

A

of starting your computer as a traditional BIOS. But it’s more modern and has better compatibility and support for newer hardware.

83
Q

what will eventually become the predominant BIOS?

A

Eventually, UEFI will become the predominant BIOS.

84
Q

computers run a test to make sure all the hardware is working correctly, this is called what?

A

This is called a Power On Self Test or POST.

85
Q

what does the BIOS run when you boot up your computer?

A

Power On Self Test or POST.

86
Q

So, if your computer successfully boots up, you may hear what?

A

a single beep

87
Q

If you hear two beeps when booting your computer it could mean what?

A

it could mean a POST error
