1
00:00:00,480 --> 00:00:09,360
are you tired of people using the word bacteria to refer to a single germ

2
00:00:07,279 --> 00:00:16,800
mixing up discrete and discrete and saying omg my facebook

3
00:00:13,679 --> 00:00:19,439
got hacked when what they really mean is

4
00:00:16,800 --> 00:00:23,039
i left my computer or phone unlocked and my idiot friend thought it would be

5
00:00:21,279 --> 00:00:28,160
funny to send those messages to your sister well one you must be a lot of fun at

6
00:00:26,240 --> 00:00:33,280
parties and two me too which is why on today's episode

7
00:00:30,960 --> 00:00:39,920
we're gonna be tackling a number of commonly misused tech terms to clear up

8
00:00:36,640 --> 00:00:42,079
any confusion and help you win your next

9
00:00:39,920 --> 00:00:46,719
internet fight so let's start then by talking about the

10
00:00:44,480 --> 00:00:52,960
venerable hard disk there are a lot of people who use the

11
00:00:49,280 --> 00:00:56,000
term hard drive to refer to any sort of

12
00:00:52,960 --> 00:01:00,239
non-removable storage in a computer but

13
00:00:56,000 --> 00:01:03,359
it actually only refers to mechanical

14
00:01:00,239 --> 00:01:06,400
spinning drives if we break it down the

15
00:01:03,359 --> 00:01:09,360
word hard refers to the rigidity of the

16
00:01:06,400 --> 00:01:14,799
discs or the magnetic platters inside the internals of floppy disks by

17
00:01:12,560 --> 00:01:19,759
contrast were flexible so

18
00:01:15,680 --> 00:01:23,119
don't refer to ssds or solid-state

19
00:01:19,759 --> 00:01:25,759
drives as hard disks or hard drives if

20
00:01:23,119 --> 00:01:31,040
you want to talk generally about mechanical drives and ssds as a group

21
00:01:28,880 --> 00:01:37,200
you say drive sticking with internal pc components for

22
00:01:33,360 --> 00:01:39,840
a minute let's talk about your GPU

23
00:01:37,200 --> 00:01:43,520
or is it your graphics card it's common to hear people use GPU to

24
00:01:42,400 --> 00:01:53,119
refer to this but the GPU actually only refers to the

25
00:01:48,960 --> 00:01:57,920
graphics processing unit this chip

26
00:01:53,119 --> 00:02:02,560
here our example is a gp104 which NVIDIA

27
00:01:57,920 --> 00:02:05,280
brands as a gtx 1070 or 1080 depending

28
00:02:02,560 --> 00:02:11,280
on how many of its processing cores are enabled from the factory

29
00:02:07,200 --> 00:02:13,680
so then it's fine to call an rx 480 a

30
00:02:11,280 --> 00:02:19,280
GPU but if you're talking about a specific model such as this Gigabyte

31
00:02:16,640 --> 00:02:24,800
wind force 8 gig you're better off calling the whole assembly a video card

32
00:02:21,840 --> 00:02:29,440
or graphics card and in the case of highly integrated devices like

33
00:02:26,480 --> 00:02:36,720
smartphones the graphics accelerator is usually part of the soc or system on a

34
00:02:33,120 --> 00:02:39,519
chip so stick with GPU in that case

35
00:02:36,720 --> 00:02:45,760
rather than calling your adreno 420 a graphics card let's move on to removable

36
00:02:42,720 --> 00:02:47,680
media namely optical disks i'm bringing

37
00:02:45,760 --> 00:02:53,599
them up to highlight the difference between disk with a c

38
00:02:50,560 --> 00:02:56,080
and disk with a k

39
00:02:53,599 --> 00:03:00,640
they both sound the same and for this reason both words are used

40
00:02:58,000 --> 00:03:08,480
interchangeably quite often to refer to cds dvds and blu-rays and these things

41
00:03:04,879 --> 00:03:12,400
but disc with a c actually specifically

42
00:03:08,480 --> 00:03:13,599
refers to optical media while disc with

43
00:03:12,400 --> 00:03:19,920
a k is used for magnetic media such as

44
00:03:16,800 --> 00:03:21,440
floppy disks and hard disks

45
00:03:19,920 --> 00:03:26,480
the more you know and coming back then to blu-rays you

46
00:03:23,760 --> 00:03:35,360
might understandably be a bit confused over how the letters hd seem to appear

47
00:03:29,840 --> 00:03:39,440
on everything from cheap 1366 by 768 tvs

48
00:03:35,360 --> 00:03:40,640
to outrageously expensive 8k displays

49
00:03:39,440 --> 00:03:46,879
well while the term hd isn't technically

50
00:03:43,840 --> 00:03:51,360
incorrect as long as the resolution is

51
00:03:46,879 --> 00:03:55,360
at least 720p or 1280x720

52
00:03:51,360 --> 00:03:58,840
tv manufacturers often use the term hd

53
00:03:55,360 --> 00:04:02,080
without any qualifiers to mean 720p

54
00:03:58,840 --> 00:04:04,640
exactly making lower end screens sound

55
00:04:02,080 --> 00:04:09,760
more appealing if you want to know unequivocally

56
00:04:06,239 --> 00:04:12,239
what each hd variant really means well

57
00:04:09,760 --> 00:04:20,239
hd is 720 as we've covered full hd is 1080p

58
00:04:15,280 --> 00:04:26,960
qhd or quad hd means 1440p

59
00:04:20,239 --> 00:04:28,400
and uhd or ultra hd means 2160p and up

60
00:04:26,960 --> 00:04:34,000
i guess words like full and ultra sound a lot sexier to

61
00:04:31,919 --> 00:04:39,360
potential buyers than a jumble of numbers but it's confusing nonetheless

62
00:04:36,800 --> 00:04:47,680
and to make things even more baffling terms like 2k and 4k

63
00:04:44,000 --> 00:04:50,240
actually refer to cinematic resolutions

64
00:04:47,680 --> 00:04:55,040
used in the movie industry meaning that true

65
00:04:51,199 --> 00:04:58,320
4k is actually a little wider than most

66
00:04:55,040 --> 00:04:59,360
4k monitors or tvs on the consumer

67
00:04:58,320 --> 00:05:04,960
market and if you've ever seen a 1440p monitor

68
00:05:02,800 --> 00:05:11,120
advertised as 2k well take a moment to shake your head

69
00:05:06,960 --> 00:05:15,360
and disgust as the actual 2k resolution

70
00:05:11,120 --> 00:05:18,240
used in cinema is nowhere close to 1440p

71
00:05:15,360 --> 00:05:23,360
real 2k is actually just a slightly wider 1080p

72
00:05:20,240 --> 00:05:25,840
so then are there any misused tech terms

73
00:05:23,360 --> 00:05:30,080
that drive you guys crazy put them down in the comments below and while you're

74
00:05:28,160 --> 00:05:36,400
at it let us know if you'd like to see a second episode of misused tech terms

75
00:05:34,400 --> 00:05:41,520
do you find yourself racing against the clock as a freelancer having so little

76
00:05:39,280 --> 00:05:46,080
time at the end of the day after you've done your work to sit down and fight

77
00:05:43,759 --> 00:05:51,199
with your accounting software it's like sparring with expenses and invoices it's

78
00:05:49,600 --> 00:05:54,320
