On this occasion, Top computers will review the Definition and Types - Types of Computer Servers in the World. already heard what a computer server and what the function of the server computer itself?. for my friend who has been in the computer world computer network must already know and are able to describe these questions, but for those who still lay out the following reviews pal hopefully can increase knowledge about the world of computer networks. ok we just on the topic of problems.
Understanding Computer Server
Computer server is a computer that is designed specifically in terms of both hardware and software terms that are used as a service provider to the need for a client computer requests a network. Usually the server computer has an important task in computer networks as data traffic as well as resource provider for use by the computer - the client computer.
To meet such demand, computer server itself is required to have high hardware specs than the computer - the client computer such as processor speed, hard drive capacity and also the size of the memory used. Not only that, the software used must have features - special features and is also resistant to attack, either from within or from outside the network of networks.

Server Operating Systems
To support the performance of a computer server then takes a special operating system that is designed for the server, below are some examples of server operating systems are typically used in a network.
1. Windows
Microsoft company has several products that are dikususkan for server operating systems. some of the products are Windows NT, Windows 2000 Server, Windows 2003 Server, the Windows 2008 server and Windows Server 2013
2. Novel Netware
Novel Netware server operating system is an operating system developed by Novel.Inc some product is NetWare 286 2.x, NetWare 3.x,NetWare 4.x, NetWare 5.x, NetWare 6.0, NetWare 6.5 and Open Enterprise Server
3. Mac OS
Mac Os is a flagship product of Apple.Inc. Apple itself also has a product server operating system, beberpa example of a product from Apple is the Mac OS X Server 1.0 (Rhapsody), Mac OS X Server 10.0 (Cheetah Server), Mac OS X Server 10.1 (Puma Server), Mac OS X Server 10.2(Jaguar Server), Mac OS X Server 10.3 (Panther Server), Mac OS X Server 10.4 (Tiger Server), Mac OS X Server 10.5 (Leopard Server), Mac OS X Server 10.6 (Snow Leopard Server), Mac OS X 10.7 (Lion Server), OS X 10.8 (Mountain Lion Server), OS X 10.9 (Mavericks Server) andOS X 10:10 (Yosemite Server 4.0)
4. Linux
Products Linux servers are very diverse, because every developer providing products that dikususkan for servers, so here only mentioned developer of Linux-based operating systems only. multiple instances of Linux distributions that can mate use for servers is Debian, Arch Linux, Fedora, OpenSUSE, Slackware, and many others.
That is some kind of operating system that can mate use to build a server.
Macam - Macam Type Server
Computer servers themselves are actually several types and differentiated based on the function of the server itself, below are several types of servers are widely used in a computer network.
1. SSH Server (Secure Shen)
SSH Server is a server computer installed a specific application so that we can control or sending an execution order to the server remotely (remote). SSH applications typically use standard port 21.
2. DNS (Domain Name System)
DNS Server is a server installed an application in order to be able to function to translate a domain name into an IP address, so my friend does not need to remember the IP number of a computer, please remember domain name of the computer. DNS servers typically use port 53 to apply.
3. WEB Server
Web Server is a server computer that is equipped with a special application that can be used to serve requests HTTP / HTTPS from the client computer and sends back the data requested in the form of document html (web), web servers can also be defined as a computer that works to save the file - file web page. Web servers typically use port 80 to access using the http protocol and port 443 for access using the https protocol.
4. DHCP Server (Dynamic Host Configuration Protocol)
A computer servers with special applications and functions to memanagement allocation of IP addresses in a network. Given this server my friend does not need to perform charging IP address on each - each client computer, because it will be assigned automatically by the server.Ports used for DHCP is port 67 or 68.
5. Mail Server
Is a server computer that is equipped with an application that serves to distribute files - files or data or information in response to a request that will be sent via email, also in Bitnet for services such as FTP (File Transfer Protocol). Ports used for Mail Server is a 110 (IMAP), 143 (POP), 25, 2525 (SMTP) to access the http protocol, 993 (IMAP), 995 (POP), 465 (SMTP) to access the https protocol.
6. Proxy Server
Proxy server is a computer or a computer application that has the function to connect a computer in a LAN network with the Internet network.Proxy servers can also be referred to as the Gateway server or a gateway that connects the local network to the outside network. Not only that, this server also has the ability to securty and penyimpana history of web pages visited my friend who had been before, so it will save bandwidth usage later. port usually used for proxy servers is port 8080.
7. Samba Server
Is a server computer equipped with an application and functions to serve the demand sharing or exchange of data between two different client computer operating system eg Linux and Ms. WIndows. Ports used for Samba Server is 137 and 139.
8. FTP Server
A computer server used for file sharing or exchange of data on the network server or client that supports TCP / IP. the port used to transfer data using FTP protocol is port 21.
9. Database Server
The database server is a computer and comes with an application that serves to provide storage services database. the port used for the Database Server usually 3306 (MySQL) and 5432 (pgsql).
Caring for Computer Servers
Because the server computer has the task of fairly heavy and usually work for 24 hours nonstop. When my friend to be a server administrator, Computer Servers care is a matter that should not be disepelahkan, the following are tips that can mate employ to care for Computer Servers for optimum performance.
1. Clean regularly from dust and dirt.
2. Pay attention to the function of the software - the software from the server itself, especially security-related software.
3. Perform data backup and file defragmentation regularly at least once a week my friend did.
That review on the definition, of sorts - types and functions of server computers as well as tips on caring for servers that utopicomputers share, may be useful to review before a computer buddy as well.
