what is a server computer, so that's the topic we will discuss this time, a server is basically a special computer that provides services for other things such as a regular desktop computer or workstation
server computer is a machine that is the center where many client computers are connected either via the internet or in a local area network they are connected to the server for a particular service or for example that service can be accessing web sites data or Email and so on server computers can be dedicated to handling one of these services only you can have one server that is specifically dedicated to websites and one server for data storage and another server for Email services usually this model is widely implemented in a large organization You can also set up the server so that it can handles all these services on the same machine setups like these are usually implemented in smaller organizations so which setup one wants to use all depends on the needs of the organization when people talk about server computers in general they are referring to centralized computers which are very powerful and connected to client goes through a computer network and they are right about that
But a server is not just a real physical computer but refers to the role that a computer takes Hi because in reality even a normal desktop computer can be set up as a server and it doesn't have to be a very powerful computer for example you guys make computer network in your home how do you have a regular desktop computer that functions as a file server then that computer will have files stored in a shared folder and then other computers can connect to that folder to access those files
You can also use a desktop computer that functions as a webserver where you will install website data on that computer and then other computers can connect and access that website page but desktop computers do have limitations because they are not designed to handle large workloads.
And they can't handle many incoming connections from users and this is not only because of their lower hardware specifications but also because of software because desktop operating systems are only capable of handling a limited number of concurrent connections hi hi on server computers need to operate its services for as long as 24 hours for seven days in a row because their role is very important for an organization and if the server experiences downtime or an error then the incident can harm the business or organization this is the reason Apa Itu server computers should be more reliable because they streams are built with powerful hardware that can run endlessly with little or no leaves Hi for example desktop computers will use processors designed specifically for desktops like Intel Core series processors and servers will use processors designed for servers like Intel Xeon processors the server must be fast and have the ability to multitask simultaneously these two processors are very powerful but there are some differences in the processors such as Xeon processors which support multiprocessing environment so they are designed to work with other processors which means you can put two or more processes solution on a motherboard designed for servers That's what God server computers to handle large workloads but desktop processors don't support this feature because they are only designed to work alone and don't work with other processors and another difference is that Xeon processors support Ashraf eh spooky is a term that refers to the ability of memory that is capable of error correction and this type of memory is used in server computers the server computer must be up and running all the time and the slightest error in memory can slow down performance server and what XC does is detect If data is processed properly by eram and he will make corrections if needed to prevent memory errors so using sst on server is just an extra precaution to prevent errors so the server doesn't auto shutdown Hi and processor Intel Core does not support SS6 but AMD processors support the feature is dated Hi Xeon processors can also support larger amount of RAM they will have bigger cache memory and they will also have More number of cores than desktop and server processors must also have a replaceable hard drive while the server computer is on which is set in the Raid configuration because if the hard drive fails then there is no data loss and the server will continue to operate because the right brain is the one who copies data on multiple hard drives and if the hard drive fails then the data can be deleted and replaced without shutting down the server Hi and then read will rebuild the data on the new Hard Drive automatically when Hi and the server must also have an extra power supply in stock to keep the server running in case of failure of the style supply and the server also needs to use the operating system servers like Windows Server Linux Mac OS servers and so on the operating systems made for servers are very powerful and stable and they are designed to run non-stop and capable of handling thousands of concurrent connections Hi there are many types of servers and when I mean I talk about the types of services that servers provide For example, a web server, a webserver, is a website house, so that any website you visit using a web browser and connect via the internet to the webserver to access the website you want, the webserver will contain all website data including html code and graphics and will also running webserver software Hi another type of server is email server Email server is one which facilitates sending and receiving of emails and you will access emails using your web browser or you can use email clients like Outlook or Thunder Bird by using Imel protocols like imap pop and smtp and Database server is another type of server this type saves data in well known and then fetched from computer on front end for example using query like sequel application so these are just some examples of software What each server does but there are more servers which is pain t Thank you very much for watching this video until we meet again in the next videos
