What is Virtual private server (VPS) ?

Virtual private server (VPS) is a term used by Internet hosting services that refers virtual machine. The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run as a server computer (i.e. to run server software). The term Virtual Dedicated Server or VDS is used less often for the same concept, however it may indicate that the server does not use burst/shared ram through multiple machines, as well as individual CPU cores. Not every hosting company is a VDS provider

Types of VPS

Networking Solutions- Affects Dedicated Servers Functionality

A network is a series of inter-connectivity of different computers to each other for any kind of communication. The reason why these days we have our computers on networking is to share our resources like printers, scanners, CD’s and to have electronic communication. The computers on network are interlinked through many ways like cables, radio waves, satellites or any other means.

Hosting is also a part of networking else we can say networking is a small form of hosting. As per the need of time, dedicated servers are available for hosting. But when the client need is to a small range or within premises than one can also go for networking instead of hosting on dedicated servers.

There are various types of Networking Solutions, which one to choose depends on the usage. While choosing networking the security should also be kept in view. Like even while transferring money we use networking. We have heard about LAN & WAN, which is commonly used type of networking. But these days various other kinds of networking are also there.

LAN (Local Area Network) - LAN is confined to relatively a smaller area. LAN is used for office buildings, computer labs in a school, university campus, huge malls, even for home when 2 or more computers are to be linked. Smaller LANs comprise of 2 or more switches interlinked with a router, cable modem etc. So the usage of LAN comes when we require high speed data transfer within the local network.. Mostly ICS (Internet Connection Sharing) is used to configure Local Area Network.

PAN (Personal Area Network) - As the name suggests when personal when computer peripherals of personal use are connected within almost a range of 10 meters /30 feet it is known as Personal Area Network (PAN). PAN is basically used to interconnect with various nearby devices. For instance if you are travelling with a PDA i. Personal Digital Assistance you don’t require to connect to the portable printer with cable but the interconnectivity without plugging anything in. Nowadays we have many PAN related devices in global market which are accessed through distinct technologies for instance; internet, extranet or intranet. Bluetooth enabled devices are also an example of PAN.

WAN (Wide Area Network) – Wide Area Network refers to connectivity within a larger area like a university in USA can communicate with one in UK in just a fraction of seconds. These types of global networks are mostly connected through satellite uplinks. WAN in comparison to LAN is used in much larger geographical areas. WAN is used for huge business and government entities i.e one can transmit data between different employees or clients irrespective of the distance. The WAN user doesn’t has its own communication lines, the service is provided with the Internet Service provider. Thus in short WAN is connectivity of various LANs rather than only of personal computers.

MAN (Metropolitan Area Network) – Metropolitan Area Network falls between LAN and WAN. MAN is larger than the geographical area covered by LAN but smaller than that covered by WAN. It covers a range of area between 5km to 50km. MAN network is provided generally via fiber optic links only. Thus MAN is inter-connectivity of various LANs with high- capacity backbone technology (Backbone is commonly said as huge that carries data gathered from smaller lines)

CAN (Campus/Corporate Area Network) – Campus Area Network as the name justifies is a network usually within a college campus, university, within the different buildings like from say administrative block to the conference hall, from students center to gymnasium etc. CAN is inter-connectivity of LAN but within a certain range of geographical area only. So basically CAN is used where one business is not confide to one building only but spread to different buildings. This is the reason why it is also known as Corporate Area Network.

With diversified solutions available in today’s techno world one can be connected through networking or through hosting on dedicated servers or even VPS window hosting, also known as Virtual Private Server is like a mini server, specifically designed as per need of the client. VPS offers much more security and one can have complete personal control on the server

The networks explained above vary from each other in many ways, speed, coverage and their usage. So a networking should be used totally depending on your necessity. So one has options to choose NETWORKING / HOSTING or VPS

Learn How Domain Name Servers (DNS) work

Tweet

Domain Name Servers (DNS) are considered as an integral part of the Internet. DNS, the worldwide network of servers, is not at all updated by any organization. Each and every machine of DNS has a unique address, IP address, having 32 bit number. IP addresses is expressed as 4 octets for example 199.254.100.8, whose process is reckoned as “dotted decimal Notation".

IP address of the websites is very difficult to remember, we want to visit again and again. But, we can remember the websites with their domain names, URLs. The DNS keeps a track of the IP addresses as well as the names.
A game of numbers and names

Domain Name Servers (DNS), distributed database, transform the machine names like www.abc.com to IP addresses like 199.254.100.8. When DNS maps the IP address to the machine name, then it is renowned as reverse mapping. When you search for the URL, www.abc.com into the search engines, the browser looks for the IP address of the URL using a directory service and this service is DNS. So, your machine contacts a DNS server to seek the IP address of the searched URL. Then, this DNS server makes contact with other DNS servers of the Internet.
All about three letter codes

A DNS server runs the DNS software and one of the high popular softwares among them is BIND (Berkeley Internet Name Domain) DNS. The root of the system is called the top, refereed as '.'. Seven immediate sub domain nodes, come under the root, are 'com', 'org', 'gov', 'mil', 'net', 'edu', 'Int', etc.

Parts of DNS:
DNS is comprised of two components, one is Nameserver and other is Resolver.

Nameserver:
Only one Nameserver is found for a group of machines. Nameserver is responsible for searching the names. If on one Nameserver, the required information is not present, then it contacts to others to look out for the information. Nameservers are well acquainted with the process of contacting the root nameserver that also knows about every authoritative nameserver.

There are three types of nameservers:

•Primary nameserver
•Secondary nameserver: Designed to serve backup purposes
•Caching nameserver: Resolve name queries without maintaining any DNS database files.

Resolver:
Resolver works on the client's machine for initiating DNS lookups. Basically, Resolver is comprised of the list of nameservers to use.

Six Quick Tips to Recover Deleted Files From a Server

A server facilitates the users to store information, protect important documents, files, etc. and share them among the computers. Acting like a mainframe, a server gives the base of easy and smooth sharing of the information by connecting multiple computers with each other. A user can rely on a server for data storing and sharing. But, what happens if someday that data is accidentally deleted! Yes, and that too without any back up. The worst thing of data deleting from the server is that it does not even go to the recycle bin.

1. Start the retrieving process by going back to the location on the server, where you saved the file. If you are not able to remember the exact location, follow steps two and three on varied folders present on the server until you find the exact location.
2. After finding the exact location of the file, right click on that folder. Select the option of "Properties" and a dialog box will open.
3. Now, browse the "Previous Versions" tab. After that, double click on the most recent version of the folder. Remember that the folder should be the same that contained the missed file. As you click on it, a long list of files appears. These files are the same that were in that folder at the time of losing data. Find your file from the list.
4. In some cases, "Previous Versions" tab is not present. If that is the case with you, it means that your server has disabled “Shadow Copies". Contact your IT administrator to make it enable.
5. As soon as you detect your missed file, right-click on it and choose the option of "Copy." Select the location, where you want to store the file and paste it there.
6. Do check it for its proper functioning by double clicking on it. If it is opening properly, close the "Properties" dialog box. As this is the copy pasted version of the previous file, so recently made changes might not be there in the file.

Sharing bit knowledge about Operating systems...

Microsoft Operating Systems
Microsoft is the most popular developer of computer operating systems. It has the greater share of the pie as their operating systems are greatly promoted throughout the world. This fact combined with their user-friendliness makes them the first choice of every new user.
Microsoft has many times criticized for adopting monopoly tactics and releasing incomplete operating systems that are vulnerable and unstable. This is the reason of the daily release of security patches, updates and service packs. Some of the most popular Microsoft operating systems are listed below:
• Ms-DOS
• Windows 95
• Windows 98
• Windows XP
• Windows 2000
• Windows Vista
• Windows 7
Linux Operating Systems
Linux is, in simplest terms, an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. The operating system (OS) relays instructions from an application to, for instance, the computer's processor. The processor performs the instructed task, then sends the results back to the application via the operating system.

Linux is an open source operating system that it was developed by Linus Torvalds and developers from all over the world. It begun as a hobby but now it is a very strong opponent to the commercial companies. Linux gains popularity every year and as a result hundreds of Linux editions have come out from many developers.
As an open operating system, Linux is developed collaboratively, meaning no one company is solely responsible for its development or ongoing support. Companies participating in the Linux economy share research and development costs with their partners and competitors. This spreading of development burden amongst individuals and companies has resulted in a large and efficient ecosystem and unheralded software innovation.
Although, Linux distributions are not so user-friendly as Windows or MAC, they are free. This is because Linux is an open source operating system. Another advantage of an open source OS is that every program that is designed for this computer OS is also free. Some popular Linux distributions for the mainstream users are the following:
• Debian GNU/Linux
• Gentoo Linux
• Mandriva
• SUSE Linux
• Fedora
• Ubuntu Linux

Apple or MAC Operating Systems
Mac OS X is a unique operating system in that it represents a rather successful coming together of paradigms, ideologies, and technologies that have usually resisted each other in the past. It is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X is perhaps one of the best examples of how a capable system can result through the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and even individuals
Apple wanted to differentiate from Microsoft’s approach to computer OS and it was the first company that designed a fully graphical interface for their computer operating systems. When MS-DOS had just a command line waiting the user to start writing, the MAC operating system offered only a graphical environment without a command line support. Apple designed two families of MAC operating systems, the MAC OS and the MAC OS X.
Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the "technical" story of Apple's operating systems
Apple’s operating systems are characterized from the easiness of use and the beautiful visuals. They offer a very nice and easy to use environment. Some versions of MAC OS X are listed below:
• 10 “Cheetah”
• 10.1 “Puma”
• 10.2 “Jaguar”
• 10.3 “Panther”
• 10.4 “Tiger”
• 10.5 “Leopard”
• 10.6 “Snow Leopard”

Types of servers

FTP servers: FTP Server is a highly functional, easy-to-use and secure server that can be used in Windows, Linux, Mac OSX and Solaris. It supports a number of file transfer protocols, including FTP, HTTP, FTPS, HTTPS and SFTP, giving your end-users flexibility in how they connect to the server.

proxy servers: In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. The proxy server evaluates the request according to its filtering rules

Main functions of proxy servers can be:

• To keep machines behind it anonymous (mainly for security)
• To speed up access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.
• To apply access policy to network services or content, e.g. to block undesired sites.
• To log / audit usage, i.e. to provide company employee Internet usage reporting.
• To bypass security / parental controls.
• To scan transmitted content for malware before delivery.
• To scan outbound content, e.g., for data leak protection.
• To circumvent regional restrictions.
• To allow a web site to make web requests to externally hosted resources (e.g. images, music files, etc.) when cross-domain restrictions prohibit the web site from linking directly to the outside domains.

web servers: A Web server is a program that, using the client/server model and the World Wide Web's Hypertext Transfer Protocol ( HTTP ), serves the files that form Web pages to Web users (whose computers contain HTTP clients that forward their requests). Every computer on the Internet that contains a Web site must have a Web server program.

Application Servers: Application servers have lion’s share in computer territory between database servers and the end user, where servers are often connected to the two. They are often referred as middleware Middleware is that software which establishes a connection between two separate applications that are otherwise apart.

List Servers: To improve the management of mailing lists list servers are used despite of what is there type. Whether they are interactive debates open to the public or one-way lists that deliver newsletters, announcements or advertising.

Fax Servers: Those organizations that want to reduce the incoming and outgoing telephone resources; a fax server is an ideal solution. However, there is a need to fax the actual document.

Mail Servers: Mail server is as important as web server s and mail servers to send and store mails on the corporate networks through LANs and WANs and across the internet.

Chat Servers: This server enables a number of people to share information in the environment of an internet newsgroup that offer real time discussion capabilities. It is used to refer to a number of different features of computer. To immediately respond to the input real-time operating systems are used.

IRC Servers: Internet Relay Chat is comprised of various independent networks of servers that allow users to connect to each other via an IRC network. It is an option for those who are seeking real time competence.

Groupware Servers: It is software that is designed to make the users able to work together, regardless of their location, through Internet or a corporate Intranet and to work together in a virtual environment.
