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.

看YouTube學英語：伺服器知識與口語練習兩不誤
這是一段關於“伺服器”的英語影片，內容專業但講解清晰，非常適合用來提升聽力和口語。影片裡不僅介紹了伺服器的定義、型別，還涉及虛擬與物理伺服器的區別，以及企業級伺服器的特點。對於英語學習者來說，這樣的內容既能積累科技詞彙，又能鍛鍊理解複雜概念的能力，可謂一舉多得。
5個實用口語短語，日常交流也能用
- on behalf of：代表……（影片中用來描述伺服器為客戶端提供功能，日常可以說“I'll do this on behalf of you”）
- dedicated to：專門用於……（如“ This room is dedicated to meetings”，和影片中“dedicated server”用法相似）
- set up：搭建、設定（影片裡多次提到“set up a server”，日常表達“Can you help me set up the printer?”）
- 24-7：全天候（企業伺服器需要“run 24-7”，日常可說“The store is open 24-7”）
- in case：以防萬一（影片中“in case a server goes down”，日常用“Take an umbrella in case it rains”）
英語影子跟讀指南：輕鬆攻克科技類內容
科技類影片可能因詞彙專業而讓影子跟讀（shadowing）變得有挑戰，但只要掌握方法，就能有效提升。首先，先聽一遍影片，熟悉內容和語速，標記聽不懂的詞彙（如“hypervisor”“RAID configuration”），查詞典理解意思。接著，逐句跟讀，重點模仿重音和語調——比如“server”“client”這些核心詞要重讀，長句如“Virtual servers use hypervisor to divide... ”要注意斷句。然後，整段複述，嘗試用自己的話總結影片內容，比如“物理伺服器是獨立的，虛擬伺服器則是共享資源的”。最後，對比原文，檢查語法和詞彙錯誤。堅持用這樣的方法練習，不僅能提升口語流暢度，還能為雅思口語練習積累素材。
記住，影子跟讀（shadowspeak）的關鍵是“緊跟”和“模仿”，哪怕一開始跟不上也沒關係，多練幾遍就能漸入佳境。利用YouTube上的英語影片做影子跟讀練習，既能學知識又能練口語，何樂而不為呢？
影片中的語法
說話人最常用的結構，並附上影片中的原話：
| 結構 | 影片中的用法 |
|---|---|
| 被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的 | is called · can be distinguished · be built |
| 定語從句 who / which + 從句 — 補充說明人或事物 | machine, which is · servers, which has |
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
