Ubuntu Server VS Ubuntu Desktop Difference

Today, a friend asked me what the difference is between Ubuntu Server and Ubuntu desktop! The difference is as follows:

Server does not have GUI

Server does not have a bunch of desktop software

The server uses different parameters at compile time, and some options are optimized (what options are optimized?)

Server supports multiprocessor symmetric technology, referred to as SMP (don't mix with multi-core)

It's basically that much, to be honest, on an IBM dual CPU (four cores per CPU) memory 32G server I installed two versions of the test (test project includes compression, multimedia format conversion, and site stress test, etc.), although the test is not very comprehensive, But it doesn't feel like the difference between the two (0 seconds or so is not the point). A guy with a phobia on the command line. You can consider using the desktop version.

PS: In fact, Linux in addition to the basic system management of some directives, need to be familiar with the product of a few, learned the configuration file and GUI management after no difference, really don't cheat you! Your little effort can make you seem more professional, just comfort yourself, hehe!

The

Server version of the kernel clock frequency is shifted from 100hz to 1khz on the desktop, which provides better performance and throughput for some server applications.

In addition, the server kernel supports SMP symmetric multiple processing (symmetrical multi-processing) technology and NUMA. The

Integrated Lamp is also a feature of Ubuntu server, eliminating the hassle of configuration.

supports "big Iron" (large server): It's a hardware solution that makes software easier and simpler to run.

LTS Support: Long-term service, quality assurance, localization, certification.

By removing the above features, you can think of Ubuntu server as a product of the desktop version that removes the GUI. The
====================================
Desktop is a livecd+ graphics installation CD (which can be read directly from the CD into the system and then installed under the graphical interface)
Servers are server versions (loaded only with command-line mode, no graphic part, no general user estimates)
Alternate is the text installation mode (the installation process is keyboard-only in points, similar to the installation interface and the first half of Windows)

Desktop and alternate after installation have a graphical interface, the general user, Server is to do the server with the
