server
1. Introduction to server
The server is called a server because the server as a whole is a member of the service to a user (client) connected to one another in a network.The server also serves to organize and provide access to users who are connected to sever .as an example of the access rights granted by the server is the right to internet access, directory access, and so on.
Apart from that server can also serve as a wall of security (Firewall.The server function is very important in a network connected to external networks such as the Internet, where it is able to prevent the relationship in which the network willing or able to damage or steal data within the network.The server can also be used as a router that connects between the other networks even different segmen.There are various services or service provided by the server to the client which is E-Mail, Domain, Web, Proxy, etc.
1.1 TAG/ID Pelayan
each server supplied by the provider will be accompanied by the name or ID TAG server .It is also known as the serial number. TAG / server ID is intended to enable the provider to identify the type of servers that they serve include the server hardware and software.the provider usually will create a data Penkala buyer information such as company name, address, date of purchase, warranty claims status, support services, the list of hardware and software list.
SPECIFICATION OF COMPUTER SERVER
The server is a computer that acts as the central controlling data access in a network (Client-Server) such as LAN, W-LAN, and others. The server can control all access PC Client.
The conclusion is that basically, the server and the PC is equally a computer, only the functions, features, and different hardware specifications. Illustration, when some PC will exchange data, so they can put on and take it on the server computer. Because the server computer specifications are usually much nicer and bigger than PC.
B. Specifications for Server Hardware
Hardware specifications that need to be considered to include the server mainboard, processor type and speed, amount of RAM, hard drive capacity, Graphics Cards (VGA), and the resolution of the monitor.

C. Different Operating Systems Server and PC
Network operating system or the computer operating system that is used as a server in a computer network operating system is almost similar to a stand-alone computer (PC), the difference is only in the network operating system, one of the computers must act as a server for other computers. In addition to the operating system used to manage network resources itself also to manage the resources of other computers that are members of the network.
The operating system must be installed into the computer in order to function properly. In a network operating system installation mode there are several options available in the form of text mode and graphics mode. Text-based operating system installation is one of the computer operating system installation mode for text display.
Use text mode if the computer hardware specifications have to be installed specifications. The text-based installation method will speed up the installation process text-based operating system installation is often used to speed up the installation process even with the less pleasant. Typically for a simple computer specifications compared with the operating system will use the text-based method.
D. Sample Operating System Server and PC
The operating system on the server is various, namely the family of Microsoft Windows (Win NT, Win 2000 Server, Windows Server 2003), Linux (RedHat, Mandrake, Debian, SuSE, Caldera, etc.), UNIX, Free BSD, Solaris.
While the PC operating system such as DOS, Microsoft Windows, Linux, Unix, Apple Macintosh Operating System, and others.
E. Features found in the Operating System Server that is not on PC
An operating system on the server is the software that controls the network and messages (eg package) and the queues of traffic, control access by multiple users to network resources such as files, and to provide certain administrative functions, including security.
The top five layers of the OSI Reference Model provides the foundation on which many network-based operating system.
Its features include: Support policies to support hardware port. Security features such as authentication, authorization, login restrictions, and access control. The name of the service and directory services. File, print, data storage, backup, and replication services. The remote access. Management Systems. Network administration and auditing graphical interface equipment. Clustering Capabilities. As well as fault tolerance and high availability.

Here are some of the components that you need to look at in terms of hardware
When planning the development of the Zimbra mail server based on the estimated
account number of ± 1000 users:
Processor: Minimum Pentium 4 3 GHz 64-bit, recommendations Xeon, 64-bit
RAM / Memory: At least 4 GB, 8 GB recommendations
Hard drive: Double Hard Drive, SATA / SCSI / SAS H / W RAID or S / W
Use hardware RAID if any, minimum scheme is RAID 1 / mirror disk,
with an optional RAID-5 if the hard drive> = 3
Network: Dual Gigabit Network Card
Bandwidth: At least 128 Kbps dedicated
In addition to the account number, the hardware specifications should also consider the number of
email traffic and access mechanisms. It could be the number of traffic but little account
email sizeable / solid and vice versa.
If the traffic is quite heavy email traffic, consider separating the server,
for example separate service services for anti spam and anti virus into
another server.
If the user access mail using webmail, amount of memory and speed
the server must be higher than if the user access mail using
email client. This is because at the time of accessing webmail user use
server resources.
While the minimum computer specifications that are used to
