HI,<br />
<br />
Can somebody explain how sites like, YouTube can have 1000 users all streaming the same vidio clip at once? &nbsp;I thought there would be some sort of limit much lower. HHow do they achieve this? &nbsp;I am sure they spread the load over numerous servers, so is it just hat they have thousands hundreds of servers hosting a particular clip?<br />
<br />
Similarly, web sites, e.g banking websites, what if 1000's of people log in on moonday morning to see if their interst has been paid. &nbsp;I guess Ive experienced not being able to log in during busy times, but how do they make it available to soo many people?

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.
