What is a server?
2
In computing, a server is a dedicated computer or device that provides functionality on behalf of other devices or clients.
3
This architecture is called the client-server module.
4
Servers can provide various functionalities, often called services, such as sharing resources or data among multiple clients,
5
or even performing computation for a client.
6
Now, a server could be dedicated to handle one of these
7
services only where you would have one dedicated server for a website, one server for data storage, and a server for email.
8
And this is a model what larger organizations use.
9
Well, you can also set up a server to handle each of these services on the same machine, which is what typically happens in smaller organizations.
10
And when we talk about servers, they're generally serving a lot of computers, so people at home Some don't need that because they only have one, two, three or four computers.
11
Servers enable you to control and distribute information, as well as a way to protect the information.
12
Servers can be distinguished into two main types of servers, a physical server and a virtual server.
13
Physical servers are dedicated servers which use the traditional CPU and RAM for that one server.
14
Virtual servers, however, use hypervisor to divide the physical server into two
15
or more virtual servers which share the resources like CPU and RAM with two or more other servers.
16
Most of the servers and enterprises in cloud are virtual servers.
17
Businesses need servers to run 24-7 because they're vital to an organization.
18
And if a server fails, then the business could suffer losses or jeopardize the business.
19
Or an organization.
20
So this is why servers need to be more reliable.
21
They need to be built with the right resources like high computing CPUs and RAM.
22
Servers and server components need to be redundant, meaning if one component or the server fails, it shouldn't impact the whole server.
23
Server.
24
Servers need to be set up in a redundant fashion, in case a server goes down, then another server should be available to serve the request from desktop clients.
25
In AWS, you can set up the servers in multiple availability zones in order to avoid an outage, similarly in Azure and GCP.
26
A server should also have a redundant hot-swappable hard drive in the RAID configuration, Because if a hard drive were to fail, then no data loss would happen,
27
and the server would still be up and running because of RAID configuration.
28
RAID makes it possible to copy the data onto multiple disks, and if a hard drive fails, then it can be removed and replaced without shutting down the whole server,
29
and then RAID would rebuild the data onto the new hard drive automatically.
30
The servers should also have redundant fiber channel adapters and power supplies.
31
Since servers are used by multiple desktop clients, they need to have multiple processor environments.
32
IBM CPU.
33
IBM servers use Power CPU in their different servers, which has a high computing CPU power.
34
AWS cloud servers.
35
They have a high computing CPU power.
36
An application server is a program that handles all application operations between users and an organization's backend, business applications, or data.
37
This type of server is typically used for complex transactions-based applications cloud server.
38
Rather than being proved by a single server or virtual server, cloud server hosting services are provided by multiple character servlets that comprise.
39
Server Operating System Any server also needs to use a server operating system, such as Linux, Windows Server, Mac, OS Server, and so on.
40
Server operating systems are robust and stable, and they're designed to run non-stop and are able to handle thousands of concurrent connections.
41
Now there are many different types of servers.
42
Types of servers.
43
There are many types of servers depending on what server is hosting on it.
44
For example, a web server.
45
A database server.
46
This type of server hosts data in the backend.
47
A web server that hosts a website.
48
The web server will run the web server software, like HTTP, NGINX.
49
It contains all the website's data, including the HTML code and graphics.
50
Another type of server is an email server.
51
An email server is what facilitates the sending and receiving of email.
52
DNS server is a server dedicated to resolving domain names.

이 비디오로 배울 수 있는 영어 실력
서버 관련 전문 용어를 자연스럽게 듣고 말하는 능력이 향상됩니다. "클라이언트-서버 모듈", "가상 서버", "RAID 구성"과 같은 단어들을 문맥 속에서 이해하고, 영어로 설명할 수 있는 실력을 기릅니다. 또한, 정보 전달형 발화의 리듬과 강세를 익혀, 복잡한 개념도 명확하게 전달하는 능력을 키울 수 있습니다.
듣고 주목해야 할 발음 특징
영어의 연결 발음과 축약형을 주의 깊게 듣습니다. 예를 들어, "what is a server"는 /wɑːt ɪz ə ˈsɜːrvər/가 아니라 /wɑːtɪz ə ˈsɜːrvər/로 연결됩니다. "they're generally"는 /ðeɪr ˈdʒenrəli/가 아니라 /ðeɪrˈdʒenrəli/로 발음됩니다. 또한, "CPU"와 "RAM"과 같은 약어는 /siːpiːjuː/와 /ræm/으로 빠르게 발음되므로, 이를 구분할 수 있는 청력이 필요합니다.
원어민처럼 말하는 방법
유튜브 영어 공부에서 중요한 쉐도잉(shadow speech) 연습을 해보세요. 비디오를 멈추지 않고 따라말하면서, 발화의 리듬과 강세를 모방합니다. "Servers can provide various functionalities"에서 "various"는 강세를 주고, "functionalities"는 뒷부분을 약하게 발음합니다. "Virtual servers use hypervisor to divide"에서 "hypervisor"는 /haɪpərˈvaɪzər/로 명확하게 발음하되, 빠르게 연결합니다. 또한, 정보를 전달할 때는 어조를 평평하게 유지하되, 중요한 용어에는 약간의 강세를 주어 청자에게 집중을 유도합니다. 이렇게 반복적인 쉐도잉 연습을 통해, 자연스러운 영어 발화 능력을 키울 수 있습니다.
서버 관련 주요 용어 정리
- Physical server: 물리적인 서버로, 전용 CPU와 RAM을 사용합니다.
- Virtual server: 하이퍼바이저를 사용해 물리적 서버를 나눈 가상의 서버입니다.
- RAID configuration: 여러 개의 하드 드라이브에 데이터를 복사해 안정성을 높이는 구성입니다.
- Web server: 웹사이트를 호스팅하는 서버로, HTTP나 NGINX 소프트웨어를 사용합니다.
이 용어들을 영어로 말하면서, 발음과 의미를 동시에 기억하세요. 쉐도잉을 할 때 이 용어들을 포함한 문장을 반복练习하면, 실제 의사소통에서도 자연스럽게 사용할 수 있습니다.
이 영상의 문법
화자가 가장 많이 쓰는 문형을 영상 속 실제 표현과 함께 정리했습니다.
| 문형 | 영상 속 표현 |
|---|---|
| 수동태 be + 과거분사 — 누가 하는지보다 무슨 일이 일어나는지에 초점 | is called · could be dedicated · can be distinguished |
| 관계절 who / which + 절 — 사람이나 사물에 대한 추가 정보 | machine, which is · servers, which has |
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.
