LEARNING OBJECTIVES

3. “Cannot establish connection to server” message of
hopelessness for those who are uploading files online,
posting photos on Facebook, downloading torrent file
from peer network, and streaming videos online. But
what is this message all about? What is the server that
this message referring to, or in other hand, what is
server?
INTRODUCTION

4.  Servers is a large data storage and processing devices that exist
either as hardware or as virtual storehouses located on the internet
or LAN. Computers or software systems act as servers that connect to
a network.
 A server can be any type of device that shares and saves information.
 Servers can both store and process information within their own
system or request it from another.
 Servers began as small devices that simply transferred data to a more
functional computer then grew in size and ability to perform more
complex functions. Now, virtual servers exist within cloud computing
platforms that are housed on the internet.
What is server ?

5. It is a physical computer
that provide services to all
client computers connected
to it, allowing them (client
to access
information or
computer)
available
resources.
SERVER

6. An entity in the client/server programming model, where
the server is a software or a program, running on one or
multiple computers, that manages resources and
services of the network, while handling requests from
different computers to access said resources.
In short, server is a software and hardware that gives
services to other hardware and software entity.

7. TYPICAL TYPES OF SERVER
1. Web Server
2. Application Server
3. FTP Server
4. Name Server
5. Application Programming Interface
6. Database Server
7. Game server
8. Media Server
9. Proxy Server
10. E Mail Server
11. Print Server
12. DNS Server
Etc…

8. TYPICAL TYPES OF SERVER
Web Servers
A web server connects to the
Internet and supports
physical data interchange
with other devices connected
to the web. On the software
side, a web server includes
several parts that control
how web users access hosted
files. At a minimum, this is an
HTTP server.
Examples: apache Webserver,
ISS Web server, Nginx
webserver…..

9. TYPICAL TYPES OF SERVER
Application Server
An application server is a server that
hosts applications or software that
delivers a business application through
a communication protocol. For a
typical web application, the application
server sits behind the web servers.
Examples: Mobile applications

10. TYPICAL TYPES OF SERVER
FTP Server
One of the oldest of the Internet
services, File Transfer Protocol
makes it possible to move one
or more files securely between
computers while providing file
security and organization as well
as transfer control.

11. TYPICAL TYPES OF SERVER
Name Server
Servers that look up
such as
addresses
mapping a domain
name to an IP. This is
basic infrastructure for
networks such as the
internet.
For example, if you type “myblog.com” into Google, the
nameserver tells the browser where that domain is located

13. TYPICAL TYPES OF SERVER
API – Application Programming Interface
A server that implements functionality for other software by
offering an API. APIs just allow applications to communicate
with one another.
Applications:
1. Access Data
2. Hide Complexity
3. Extend functionality
4. Security

14. TYPICAL TYPES OF SERVER
Database Server
Provides access to a database. It
is a server which uses a database
application that provides
database services to other
computer programs or to
computers.
Examples of proprietary database applications include
Oracle, IBM Db2, Informix, and Microsoft SQL Server.
Examples of free software database applications include
PostgreSQL; and under the GNU General Public License
include Ingres and MySQL. Every server uses its own
query logic and structure.

15. TYPICAL TYPES OF SERVER
Game Server
a server which is the authoritative
source of events in a multiplayer
video game. The server transmits
enough data about its internal
state to allow its connected clients
to maintain their own accurate
version of the game world for
display to players.

16. TYPICAL TYPES OF SERVER
Media Server
Delivers media such as
streaming video or audio.
A media server is a computer
appliance or an application
software that stores digital
media (video, audio or images)
and makes it available over a
network.

17. TYPICAL TYPES OF SERVER
Proxy Server
Acts as an intermediary between
clients and servers to implement
functions such as security, monitoring
or anonymization.

18. TYPICAL TYPES OF SERVER
List Server
servers offer a way to better
manage mailing lists, whether
they be interactive
discussions open to the public
or one-way lists that deliver
announcements, newsletters
or advertising.

19. Advantage of using server computer
Server contain more powerful processors than a
desktop computer.
Servers support advanced RAM technologies
Have higher storage capacity as multiple disks can
be inserted into them

20. Advantage of using server computer
Manufactured and optimized for 24/7 operation
Built to support multiple user applications and
multiple user access
Have multiple NIC
Easier to apply security policies

21. Server vs. Workstation
A server is an application or device that performs service
for connected clients as part of client server architecture.
A workstation is a personal computer that is used for high
end applications such as graphic design, video editing,
CAD, 3-D design, or other CPU and RAM intensive
programs.

22. Server Operating System
A server is an application or device that performs service for
connected clients as part of client server architecture.

23. Server Operating System
developed by Microsoft, as
a part of the Windows
Network family, which is
getting developed
concurrently with
Windows 10 OS.

24. Server Operating System
developed by Red Hat and targets toward the commercial computer
market. It provides open source software solutions and products to
various enterprises and communities around the world

25. Server Operating System
designed to work on multi-platform that can run everywhere from the
Desktop PCs, the smartphones, and the tablet to the server and the
cloud environment.

26. Server Operating System
A community enterprise OS, that is a free rebuild of open source
packages from the popular Red Hat Enterprise Linux.

27. Server Operating System
It is designed for servers, mainframes, and workstations but can be
installed on desktop computers for personal and as well as testing
purpose.

28. Server Operating System
a proven operating system that is available in the cloud, on premises, or
as an embedded system. It is built for enterprise-level experience.

29. Server components
Physical servers are made up of the following parts:
Motherboard: A motherboard connects all parts of a server. A motherboard's size
dictates the amount of storage and the number of hard drives that can connect to a
server.
Central Processing Unit (CPU): The CPU controls the overall functions of a server. It's
the center for all processing within a server device. CPUs are measured by processing
speed.
Memory: This part of a server dictates the amount of storage available. Memory
needs to be compatible with the motherboard.

30. Server components (Cont)
Hard drives: A hard drive stores both user and software data for a computer. It uses a
controller card for optimum processing functions. A server housing large amounts of
data may need multiple hard drives.
Network connection: A server needs to connect to a network in order to function. A
good network connection will ensure a server is able to receive and respond to user
requests. Many motherboards already contain a network adapter however, if they
don't, the server will need an external network connection installed.
Power supply: Servers that provide data to large numbers of clients need a bigger
power supply than a typical personal computer. Most servers need a power supply of
at least 300 watts and also should have more than one inputs with redundancy
