Whereas learning to work on a desktop is very easy. Even a newbie can learn how to work on a desktop in just a few days. The below table helps in summarising the differences between a server and a desktop. The straightforward answer is yes. A desktop computer can run as a server because a server is also a computer with advanced hardware parts.
A server has functionalities that can be shared over a network with many other computers called clients. For example, a desktop computer can act as a file server to share files with clients on the same network. A desktop computer is not as secure as a server. So that was all about the difference between a desktop and a server.
In short, a desktop is used by an individual or by an organization for their employees. Although both are computers but still very different from each other. If you are an individual, you would be using a desktop at your office or for your personal use, but if you are an IT administrator professional in an organization, you would be working on servers.

On the client side, the TCP stack will look at the port number in the packet, and route it to whichever process was assigned that port number. As such, a client won't use port -- it'll use whatever port the stack assigns to it. When another process on the same machine connects to the same server, it won't use port either -- it'll use another port that gets assigned to it.
The network stack is responsible for ensuring that each gets a unique port number. For what it's worth, TCP ports are divided into three ranges.
These are for servers to use, and it's possible the OS will take some special steps to protect these a bit. From to are the registered port numbers. These are generally more loosely controlled than the well known ports. Almost anybody can set up to listen on them, but the IANA maintains a registry of specific purposes for particular ports.
According to the registry, port is for the remote whois protocol. From to are the dynamic ports -- when a client connects to a server, it will normally get a local port number in this range.
You can, of course, write a server and have it bind to a port number in this range if you prefer e. However, if you're defining your own protocol, why not pass a ClientID back and forth between client and server? A connection is identified by a tuple protocol, source IP, source port, dest IP, dest port. That's how you can distinguish connections. For a client to connect multiple times to the same server, from the same machine, it uses multiple ports usually ephemeral to the same known listener port.
The client side port binding is done automatically by the OS when you use the connect TCP function so you don't really need to manage this stuff. As for the application server, according to our definition, an application server exposes business logic to client applications through various protocols, possibly including HTTP. While a Web server mainly deals with sending HTML for display in a Web browser, an application server provides access to business logic for use by client application programs.
The application program can use this logic just as it would call a method on an object or a function in the procedural world. Such application server clients can include GUIs graphical user interface running on a PC, a Web server, or even other application servers.
The information traveling back and forth between an application server and its client is not restricted to simple display markup. Instead, the information is program logic.
Since the logic takes the form of data and method calls and not static HTML, the client can employ the exposed business logic however it wants. Moreover, the application server manages its own resources. Such gate-keeping duties include security, transaction processing, resource pooling, and messaging. Like a Web server, an application server may also employ various scalability and fault-tolerance techniques. As an example, consider an online store that provides real-time pricing and availability information.
Most likely, the site will provide a form with which you can choose a product. When you submit your query, the site performs a lookup and returns the results embedded within an HTML page.
The site may implement this functionality in numerous ways. I'll show you one scenario that doesn't use an application server and another that does. Seeing how these scenarios differ will help you to see the application server's function. An easy to understand example is the web browser, be it Google, Yahoo, Bing and anything in between.
These servers manage and store data that is used by other devices connected to the network. Much like AOL, Gmai and Microsoft Outlook, a mail server holds the purpose of sending and receiving electronic mail, aka e-mails, to a specific recipient. This communication is open to local users and remote senders. A file server is a device that stores and manages data, such as a hard drive or USB.
These devices communicate with other devices on the network granting access to the information stored within the file server.
Google Drive can also be used as a file server. These types of servers provide the logic for the app — they are programs in a network that communicate with other devices. In summary, all servers manage and store data in some way, they also share information and order computations. Every server type is intended to carry out a particular purpose in order to ensure seamless operation and connectivity.
