1
An embedded system is an autonomous electronic and computer system, with the goal of executing a well -defined task in real -time.
2
Here we see the first difference from a PC, which is versatile because it can run many types of applications, whereas an embedded system only performs a dedicated function.
3
Furthermore, embedded systems are often invisible to the user
4
because they are integrated within a device
5
that itself serves a function for example a microwave oven an
6
airplane a washing machine etc domains of embedded systems are primarily
7
found in the following areas first we have general computing similar to pc applications
8
but integrated into an embedded system such as smartphones tablets etc
9
then systems control such as motor control automotive applications aviation
10
and navigation systems also signal processing with examples like radar sonar
11
and video compression and finally communication and networks involving information transmission telephony
12
and the internet for example
13
so as you can see there are many embedded systems today
14
embedded systems far outnumber computers in terms of quantity an embedded system typically consists of microcontroller that solves a specific problem,
15
often subject to time and size constraints.
16
A microcontroller is an integrated circuit that combines essential computer elements that includes a processor to provide computing power,
17
a central memory, often limited, containing the program and data, sensors acting as inputs to receive information,
18
such as temperature, vibration, humidity,
19
proximity, pressure, or contact, and actuators or outputs that allow the embedded system to perform actions on the external real world environment.
20
These can include LEDs, display screens, speakers, alarms, or a combination of these, as seen in an airplane cockpit.
21
Finally, embedded systems are equipped with communication means that enable them to communicate via the internet with external applications and end users.
22
This is the phenomenon of the Internet of Things, or IoT.
23
It's important to note
24
that there is a significant difference between embedded systems based on the device in
25
which they are embedded and the complexity of the task they perform.
26
On one hand, there are small -scale embedded systems with very simple hardware
27
and software sufficient for basic tasks like a coffee machine that transforms your coffee capsule.
28
On the other hand, there are advanced and sophisticated embedded systems found in devices like airplanes,
29
designed to facilitate piloting and improve safety.
30
The design of an embedded system typically depends on the characteristics and constraints of the device in which it is integrated.
31
This includes considerations such as weight and size, program size and required execution time, especially for embedded systems with basic hardware.
32
The appropriate hardware to run the software Energy consumption,
33
optimized based on the size and complexity of the embedded system Continuity of operation,
34
which requires embedded systems to withstand harsh external conditions such as vibrations, shocks, temperature variations, and weather And finally,
35
manufacturing costs, determined by the aforementioned constraints Thanks a bunch for tuning in.
36

37
Goodbye.

이 레슨의 어휘와 말하기 포인트
이 C1 수준 말하기 레슨은 영상 “Embedded Systems Explained in 3 minutes”을(를) 바탕으로 합니다. 가장 자주 반복되는 단어는 다음과 같습니다: embedded, integrated, applications, device, computer. 이 영상에는 섀도잉할 문장 37개와 단어 509개가 있습니다. 말하는 구간의 길이는 3:48입니다. 화자는 분당 약 134단어의 일정한 속도로 말해서 섀도잉하기에 편한 속도입니다. 영어에서 가장 많이 쓰이는 3,000단어에 속하는 단어가 75%뿐이라 어휘가 어려운 편입니다.
이 영상의 핵심 어휘
영상에서 가장 어려운 단어 15개를 발음, 뜻과 함께 정리했습니다.
| 단어 | 발음 | 뜻 |
|---|---|---|
| airplane 명사 | /ˈɛɹˌpleɪ̯n/ | 비행기, 항공기 |
| vibration 명사 | /vaɪˈbɹeɪʃən/ | 진동 |
| aforementioned 형용사 | /əˈfɔɹˌmɛn.ʃənd/ | 상기 |
| withstand 동사 | /wɪðˈstænd/ | 맞서다, 버티다 |
| versatile 형용사 | /ˈvɜː.səˌtaɪl/ | 다재다능한 |
| capsule 명사 | /ˈkæps(ə)l/ | 삭과 |
| microwave 명사 | /ˈmaɪkɹoʊˌweɪv/ | 마이크로파 |
| humidity 명사 | /hjuːˈmɪd.ə.ti/ | 습도, 습기 |

이 영상으로 연습하는 방법
- 먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
- 보통 속도로 한 문장씩 섀도잉하고, 화자의 리듬과 맞을 때까지 반복합니다.
- 자신의 목소리를 녹음해 원본과 비교하고, airplane, vibration, aforementioned 같은 단어에 특히 주의합니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
