2. Desktop Vs Server base Operating System
Server base:
• A server is a physical computer (a computer
hardware system) dedicated to run one or more
services (as a host), to serve the needs of the
users of other computers on a network.
• Depending on the computing service that it offers
it could be a database server, file server, mail
server, print server, web server, gaming server, or
some other kind of server.

3. Desktop Vs Server base Operating System
Desktop:
• A desktop computer is a personal computer (PC) in a
form intended for regular use at a single location, as
opposed to a mobile laptop or portable computer.
• Early desktop computers are designed to lie flat on the
desk, while modern towers stand upright.
• Most modern desktop computers have separate
screens and keyboards.
• Prior to the widespread use of microprocessors, a
computer that could fit on a desk was considered
remarkably small.

4. Desktop Vs Server base Operating System
• Early personal computers, like the IBM PC, were "desktop"
machines, with a horizontally oriented computer case,
usually intended to have the display screen placed on top
to save space on the desktop.
• In modern usage the word "desktop" usually refers to
tower cases that are in fact more often located on the floor
under the desk than on a desk.
• Technically speaking desktop and tower computers are two
different styles of computer case that use desk space in
varying ways Cases intended for home theater PC systems
are usually considered to be desktop cases in both senses,
regardless of orientation and placement.

5. Difference
• Almost any computer that meets the minimum hardware
requirements can run a server operating system that alone
does not make a desktop computer a true server.
• Even if the desktop computer had similar processor speeds,
memory and storage capacity compared to a server, it still
isn't a replacement for a real server.
• The technologies behind them are engineered for different
purposes.
• A desktop computer system typically runs a user-friendly
operating system and desktop applications to facilitate
desktop-oriented tasks.
• In contrast, a server manages all network resources.

6. Difference
• Servers are often dedicated (meaning it
performs no other task besides server tasks).
• Because a server is engineered to manage,
store, send and process data 24-hours a day it
has to be more reliable than a desktop
computer and offers a variety of features and
hardware not typically used in the average
desktop computer.

7. Difference
1. With server OS we can manage desktop OS.
Server Os is higher version of Desktop OS.
2. Server OS gives centralised administration for
users shared resources higher security. But
Desktop OS gives local machine administration
only.
3. Server OS is fully covered & managed security.
For (ex) Domain Controller application server
print server etc. We make server with security.
for Desktop OS Normal PC. We make low level
security.
