Server Platform : Linux is referred to as a server platform because it has the capability to form the foundation for which an operating system can be built and has been used as an alternative to the Microsoft Windows operating system. Because of its capability to act as a platform it can also be used as a microchip for other devices and appliances.
The next thing we wanted the answer to was, what is a Linux server?
One way to consider this is a Linux server is a variant of the Linux operating system that is designed to handle more intense storage and operational needs of larger organizations and their software. Linux servers are widely used today and considered amongst the most popular due to their stability, security, and flexibility, which outstrip standard Windows servers.
These are designed to handle the most demanding business application requirements, such as network and system administration, database management, and web services. Linux servers are often chosen over other server operating systems for their stability, security, and flexibility.
Linux Kernel: The Linux kernel is what distinguishes the Linux operating syste m from other systems. The kernel is located in the central portion of the operating system and controls the operating system security, hardware interfaces, and acts as the primary resource for the operating system itself.
How web servers work?
A page on internet can be viewed, when the browser requests it from the web server and the web server responds with that page.
What is the basic implementation of a TCP/IP server?
But the basic implementation is a simple client server program in which the client and server talk to each other. For example, telnet or ftp services are accessed through the inet program which hides all the details of services.
One idea is that Linux Network Stack With TCP/IP model, during the network transmission, the data packets will be processed layer by layer according to the protocol stack, and the protocol header of the upper layer will be encapsulated and send to the next layer.
This of course begs the question “What is the purpose of TCP functions?”
These perform any necessary actions (the TCP functions may send out packets to end the TCP connection) and then clean up any data structures they have remaining.
How are TCP file descriptors tracked by the kernel?
For each TCP file descriptor tracked by the kernel there is a struct tracking some TCP-specific info (e. g. sequence numbers, the current window size, and so on), as well as a receive buffer (or “queue”) and a write buffer (or “queue”). I’ll use the terms buffer and queue interchangeably.
