So, we will be able to get the video to get the video.
3
So, we will start with the video.
4
So what's the day-to-day work of someone in IT support like?
5
Well, it varies a ton based on whether you're doing in-person
6
or remote support and at a small business or a large enterprise company.
7
And there's really no such thing as day-to-day work since the puzzles and challenges are always new and interesting.
8
But in general, an IT support specialist makes sure that an organization's technological equipment is running smoothly.
9
This includes managing, installing, maintaining, troubleshooting, and configuring office and computing equipment.
10
This program is designed to prepare you for an entry-level role in IT help desk support.
11
You'll learn how to set up a user's desktop or workstation, how to install the computer applications that people use the most.
12
You'll learn how to fix a problem or troubleshoot when something goes wrong, and how to put practices in place to prevent similar problems from happening again.
13
Not only will you learn the technical aspects of troubleshooting a problem, you'll also learn how to communicate with users in order to best the system.
14
We'll also show you how to set up a network from scratch to connect to the internet
15
and teach you about how to implement security to make sure your systems are safe from hackers and other risks.
16
For me, my favorite part of IT support is the problem-solving aspect.
17
I love to exercise my creativity to spin up a solution to a user's issue.
18
Being an IT generalist also gave me the flexibility to learn
19
and practice so many different skills and eventually determine where I want to focus my career.
20
Plus, when things go wrong or you fail at something in IT, you can take the feedback from those mistakes and be better equipped to tackle them the next time around.
21
Using failure as a feedback is an important skill both in IT and in life.
22
For me, that's why I was so attracted to the IT field.
23
I love the process of problem-solving and constantly stretching myself to learn and grow.
24
There's also never been more opportunity to get into the IT industry than now.
25
Not only is the field of IT incredibly diverse, but job prospects are also booming.
26
It's projected that IT jobs in the US alone will grow 12% in the next decade.
27
That's higher than the average for all other occupations.
28
So what does this all mean?
29
There are thousands of companies around the world searching for IT professionals like you.
30
So the main gist is that IT is totally awesome and full of opportunity, and we're so excited that you're here.
31
So let's dive right in.
32
On July 20th, 1969, one of the most phenomenal events made its way into the history books.
33
when the Apollo 11 completed its historic mission to the moon.
34
While the most brilliant minds helped to make sure that the Eagle had landed, computers also played a significant role.
35
The guidance system that navigated the spacecraft was one of the earliest forms of modern computing.
36
That same computer, the one that helped America's lunar dreams become a reality, took up the space of an entire room
37
and had one ten-thousandth the computing power of the thing
38
that almost every one of you carry in your pockets today, a smartphone computer hardware
39
and software have had such a dramatic evolution
40
that what was once only used to power rockets now shapes
41
the entire way our world functions think about your day did
42
you grab a snack turn on your TV take a drive
43
in your car computers were along for the ride literally computers are everywhere
44
so here's the rundown by the end of this course you'll understand how computers work
45
and get a grasp of the building blocks of IT we're
46
gonna cover the basics of how computer hardware performs calculations
47
and we're gonna actually build a computer from the ground up we'll look at how operating systems control
48
and interact with hardware we'll take a look at the internet
49
and get a better understanding of how computers talk to each other we'll also spend time learning about how applications
50
and programs tie all of this together
51
and let humans interact with these systems finally we'll cover important lessons on problem-solving with computers
52
and cover the communication skills that are so critical
53
when interacting with others in IT whether you're looking for a job in IT industry
54
or you just want to learn how your laptop connects to
55
the internet understanding how computers work at every level can help you in your day-to-day life
56
and in the workplace
57
but first let's take a step way way back back to
58
where it all began even before the Apollo 11 mission touchdown
59
so you can understand how and why we use computers today
60
When you hear the word computer, maybe you think of something like a beefy gaming desktop with flashing lights, or maybe you think of a slim and sleek laptop.
61
These fancy devices aren't what people had in mind when computers were first created.
62
To put it simply, a computer is a device that stores and processes data by performing calculations.
63
Before we had actual computer devices, the term computer was used to refer to someone who actually did the calculation.
64
You're probably thinking, that's crazy talk.
65
My computer lets me check social media, browse the internet, design graphics.
66
How can it possibly just perform calculations?
67
Well, friends, in this course, we'll be learning how computer calculations are baked into applications, social media, games, etc. All the things that you use every day.
68
But to kick things off, we'll learn about the journey computers took from the earliest known forms of computing into the devices
69
that you know and love today.
70
In the world of technology, and if I'm getting really philosophical in life, it is important to know where we've been in order to understand where we are and where we are going.
71
Historical context can help you understand why things work the way they do today.
72
Have you ever wondered why the alphabet isn't laid out in order on your keyboard?
73
the keyboard layout that most of the world uses today is the QWERTY layout distinguished by the Q, W, E, R, T,
74
and Y keys in the top row of the keyboard the most common letters
75
that you type aren't found on the home row where your fingers hit the most
76
but why there are many stories
77
that claim to answer this question some say was developed to slow down type it
78
so they wouldn't jam old mechanical typewriters of this claim it was meant to resolve problem for telegraph operators.
79
One thing is for sure, the keyboard layout that millions of people use today isn't the most effective one.
80
Different keyboard layouts have even been created to try and make typing more efficient.
81
Now that we're starting to live in a mobile-centric world with our smartphones, the landscape for keyboards may change completely by typing fingers are crossed.
82
In the technology industry, having a little context can go a long way to making sense of the concepts you'll encounter.
83
By the end of this lesson, you'll be able to identify some of the most major advances in the early history of computers.
84
Do you know what an abacus is?
85
It looks like a wooden toy that a child would play with, but it's actually one of the earliest known computers.
86
It was invented in 500 BC to count large numbers.
87
While we have calculators like the old reliable TI-89s or the ones in our computers, the abacus is actually still used today.
88
Over the centuries, humans built more advanced counting tools but they still required a human to manually perform the calculations.
89
The first major step forward was the invention of the mechanical calculator in the 17th century by Blaise Pascal.
90
This device used a series of gears and levers to perform calculations for the user automatically.
91
While it was limited to addition, subtraction, multiplication, and division for pretty small numbers, it paved the way for more complex machines.
92
The fundamental operations of the mechanical calculator were later applied to the textile industry.
93
Before we had streamlined manufacturing, looms were used to weave yarn into fabric.
94
If you wanted design patterns on your fabric, that took an incredible amount of manual work.
95
In the 1800s, a man by the name of Joseph Ricard invented a programmable loom.
96
These looms took a sequence of cards with holes in them.
97
When the loom encountered a hole, it would hook the thread underneath it.
98
If it didn't encounter a hole, the hook wouldn't thread anything.
99
Eventually, this spun up a design pattern on the fabric.
100
These These cards were known as punch cards.
101
And while Mr. Jacquard reinvented the textile industry, he probably didn't realize that his invention would shape the world of computing and the world itself today.
102
Pretty epic, Mr. Jacquard.
103
Pretty epic.
104
Let's fast forward a few decades and meet a man by the name of Charles Babbage.
105
Babbage was a gifted engineer who developed a series of machines
106
that are now known as the greatest breakthrough on our way to the modern computer.
107
built what was called a difference engine.
108
It was a very sophisticated version of some of the mechanical calculators we were just talking about.
109
It could perform fairly complicated mathematical operations but not much else.
110
Babbage's follow-up to the difference engine was a machine he called the analytical engine.
111
He was inspired by Jacquard's use of punch cards to automatically perform calculations instead of manually entering them by hand.
112
Babbage used punch cards in his analytical engine to allow people to pre-define a series of calculations they wanted to perform.
113
As impressive as this achievement was, the analytical engine was still just a very advanced mechanical calculator.
114
It took the powerful insights of a mathematician named Ada Lovelace to realize the true potential of the analytical engine.
115
She was the first person to recognize that the machine could be used for more than pure calculations.
116
She developed the first algorithm for the engine.
117
It was the very first example of computer programming.
118
An algorithm is just a series of steps that solve specific problems.
119
Because of Lovelace's discovery that algorithms could be programmed into the analytical engine, it became the very first general-purpose computing machine in history.
120
And a great example that women have had some of the most valuable minds in technology since the 1800s.
121
We've covered a lot of ground already.
122
Learning about how primitive counting devices like the Abacus evolved into huge, complex devices like the analytical engine proof
123
that there was life before social media in the next video
124
we'll learn about how these mechanical machines made the leap into modern computing

練習のヒント
このビデオのスピードは中程度で、トーンは親しみやすいため、英語シャドーイングの初心者にも適しています。まず、ビデオを1回聴いて全体の流れを把握し、次に1文ずつ止めながら繰り返し真似してみてください。発音を良くするコツは、母音の長さや子音の強弱に注意することです。例えば「troubleshoot」の「oo」の音を伸ばすことで、より自然な発音になります。また、shadowing siteを利用して、自分の発音とネイティブの発音を比較することも効果的です。繰り返し練習することで、リズムとイントネーションを身につけ、自然な会話ができるようになります。
この動画の文法
話し手がよく使っている文型を、動画の実際の表現とともに紹介します。
| 文型 | 動画での表現 |
|---|---|
| 受動態 be + 過去分詞 — 誰がするかより、何が起きるかに焦点を当てる | is designed · are baked · isn't laid |
| 現在完了形 have/has + 過去分詞 — 過去の出来事が今も関係している | There's also never been · have had · we've been |
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
