1. 0:00Motherboard. The motherboard is a wide
2. 0:02and flat circuit board and it's the main
3. 0:04component of the computer where every
4. 0:06other component gets connected. Its goal
5. 0:08is to make the different parts of the
6. 0:09computer communicate with each other.
7. 0:11It's relatively cheap if compared
8. 0:13against other components. Even though
9. 0:14it's arguably the most important one, it
10. 0:16can be considered the heart of the
11. 0:18computer. CPU. The CPU, also known as
12. 0:22the central processing unit or
13. 0:23processor, is the brain of the computer.
14. 0:25And although it usually has very low
15. 0:27data storage, it's really good at using
16. 0:29it for things like complex mathematical
17. 0:31operations, [music] reading through
18. 0:32massive lists, etc. It's where most of
19. 0:35the programs are run from and basically
20. 0:37everything that happens in a computer
21. 0:38goes through the CPU at some point. Hard
22. 0:41drive. It's where all of your data is
23. 0:43stored. So when the computer says you're
24. 0:45running low on space, it means that your
25. 0:47hard drive is almost full. Hard drives
26. 0:49are good at storing a lot of data, but
27. 0:51they're slow at accessing it since most
28. 0:53of them are made up of spinning discs
29. 0:55and share their data through a small
30. 0:56wire. For this reason, it isn't always
31. 0:59going to be able to give the needed
32. 1:00information to the CPU. To avoid this
33. 1:02problem, we use the RAM. RAM. The RAM
34. 1:05stores data just like the hard drive,
35. 1:07but with much less space available. The
36. 1:09good thing about the RAM is how fast it
37. 1:11can access information, making it useful
38. 1:14to quickly communicate to the CPU the
39. 1:16information that would take too long for
40. 1:18the hard drive to access. Every time you
41. 1:20see a loading screen in a video game,
42. 1:22it's because the CPU is taking the
43. 1:24needed data from the hard drive to the
44. 1:25RAM, so it can access it much more
45. 1:27quickly when you're playing. The RAM is
46. 1:29connected through a long, thin stick
47. 1:31instead of a small wire like the hard
48. 1:32drive. One thing to remember is that you
49. 1:34can't permanently store data on the RAM.
50. 1:36It's a short memory system, and every
51. 1:38time you turn off your computer, the
52. 1:40data on it gets wiped. SSD. The
53. 1:43solidstate drive has the same goal as
54. 1:45the hard drive, but it's faster and more
55. 1:47durable. It's a newer technology, and in
56. 1:49some computers, it's used with hard
57. 1:51drives or completely alone. It's also
58. 1:53usually more expensive. Graphics card.
59. 1:55To create 3D worlds from complex
60. 1:58calculations, the computer has to do a
61. 2:00massive amount of work. But a really
62. 2:01difficult part comes in when it's time
63. 2:03to show those worlds on your screen.
64. 2:05This is where the graphics card comes
65. 2:06in, which is basically an entire
66. 2:08standalone computer dedicated only to
67. 2:10showing the right things on your screen,
68. 2:12deciding which pixels need to light up
69. 2:14and in what color. Some CPUs already
70. 2:16come with an integrated graphics card,
71. 2:18but they're usually less powerful than a
72. 2:20normal single graphics card. Power
73. 2:22supply. As the name suggests, this
74. 2:24component takes the electricity from an
75. 2:26outlet and puts it into the computer,
76. 2:28making it possible to use it. It has to
77. 2:30be powerful enough for your other
78. 2:31components. Case. A case is simply a box
79. 2:34of plastic where every part goes. The
80. 2:36most popular formats are mini tower,
81. 2:39midtower, and full tower depending on
82. 2:41the size they have. The choice of the
83. 2:42case should come after having decided
84. 2:44the sizes of the other components to
85. 2:46make sure that everything fits in it.
86. 2:48Cooling system. Some areas of the
87. 2:50computer, like the CPU and graphics
88. 2:52card, generate a lot of heat and would
89. 2:55fry every other component and themselves
90. 2:57if it weren't for a cooling system. A
91. 2:59computer can have air cooling or liquid
92. 3:00cooling, each with its own pros and
93. 3:02cons. Wireless card. If your computer
94. 3:05supports Wi-Fi, which gives you access
95. 3:07to the internet without using Ethernet
96. 3:09cables, it has a wireless
