Defintion
of Computer Server
Have you ever heard
the term of computer server? Maybe once and not infrequently you’re
wondering about the definition, usability, and its parts. Indeed, what is a
server computer? It is a computer with a particular service on a network. This
computer is like a parent who store and manage information, and distribute to
other computers in order to be used together.
This type of computer
is used either in the
Internet or in an intranet network. In general, this computer will operate
for 24 hours without stopping in order to provide maximum service to the users.
It also has a working system has a server computer specs that are much
different from the client computer. It must be great to many times to be able
to provide long-term duration of service and quality remains.
Good specs certainly
not just on the outside or the hardware, but the software is also included.
This is evidenced through the operating system owned by the server with a
special design. Some of them are as follows:
1. Microsoft Windows
Server 2008
2. Sun Solaris
3. UNIX
4. Redhat Linux
Components
of Server
Components of the
server computer consist of a wide variety of hardware together with regular
components in the client computer. Nevertheless, the components on the server
as well as a class have a much higher quality because it will function with
many compositions. The following explanation will tell you what these
components are.
Motherboard
The motherboard is a circuit board inside
a computer with
all the components in your computer be connected. This is the core of a
computer that is referred to as ‘ mother ‘.
The main components on the motherboard
including the processor (CPU), a circuit called the chipset, memory, expansion
slots, IDE hard drive controllers, and input / output ( I / O ) ports for
devices such as keyboard, mouse, and printer. Some motherboards also have
additional features such as graphics adapters, SCSI disk controller, or network
interface.

Processor
The
processor, or CPU, is the brain of the computer. Although the processor is not
the only component that affects the overall system performance, but this is the
first component of people think of when they want to buy a computer server.
Intel has four processor models are designed and used in the server computer :
Itanium
2 : a clock speed of 1.60GHz, the processor cores 1-2
Xeon
: 1.83 – 2.33GHz clock speed, processor cores 1-4
Pentium
D : 2.66 – 3.6GHz clock speed, 2 -core processor
Pentium
4 : 2.4 – 3.6GHz clock speed, 1 core processor
Memory
When
you want to have a category of computer servers, then do not make too much
savings. Many types of memory available, so you need to choose the right type
of memory to match the memory
supported by the motherboard. Total memory
capacity of the server depends on the motherboard. Most new servers can support
12GB of memory, and some can support up to 32GB.
Hard drives
Most
desktop computers use a cheap hard drive called IDE drives (sometimes also
called ATA). The drive is enough for individual users, but because the
performance is more important for a server, other types of drives are known as
SCSI is typically used instead. For best performance, use SCSI drives with a
SCSI controller card.
Recently,
a new type of so-called cheap SATA drives has appeared on a desktop computer.
SATA drives are also being tested continuously for computer servers.
The network connection
The
network connection is one of the most important parts of any server. Many
servers have a network adapter built into the motherboard. If your server is
not equipped with it, you will need to add an adapter card for a separate
network.
Power supply
Because
the server usually has more devices than regular desktop computers, would
require greater power (300 watts in general). If the server has a hard drive in
smaller amounts, may require greater power.
The Functions of Computer Servers
After
I provide an understanding of an existing operating system on the server
computer. Now it’s time to switch to a function or usefulness of the server
itself. There are several functions that can be found on this server, among
others, are as follows.
Application server
This
server has the function to store a wide variety of applications that will be
accessed by the client computer. For example, the central computer or server
stores online application transaction that can later be used on the intranet or
internet.
Proxy
Proxy
server is a function of a meaningful set of network traffic with proxy
settings. Many people are more familiar with the proxy server in order to
connect between the client computer with the internet.
Database server
Provides
access to the database is one of the most important functions of a computer
server. A relational database storage structure information is compact and
efficient, and allows quick access to large volumes of data.
In
a business office setting, a database can be used to store the contact details
of the customer and order information, as well as shipping and payment notes.
By accessing the server via a local network, multiple employees can retrieve
and update information from the database throughout the day as the business is
conducted.
Printer server
Used
to set the printer to work on a network. This is
what causes the printer to be used by a wide variety of computers and are
connected in a network.
