What is difference between web server and proxy server?
What is the difference between a packet filter and a proxy?
Preface
So you think you know what a proxy is? Well if you are familiar with the old Web Proxy servers please forget everything you thought you knew about proxies. We are talking about something very different. The old proxy servers took web requests from clients and checked to see if it had that page already cached, and if not, it would then redirect the client request to the internet, if the request was allowed. A linear flowchart would look something like:
- Client request for KnowtheNetwork.com -> Proxy checks cache -> Not found, forward request
- Client request for Google.com -> Proxy checks cache -> Cached page found, replies w/ cached page
- Client request for badwebsite.com -> Proxy checks cache -> Proxy denies the request based on policy
A modern day proxies are entirely different.
What is the difference between web server and web browser?
== ==
Web browser means the browser you are using to see the websites ex: internet explorer, firefox, opera,safari etc...
A Web browser is somthing used to search the web.
And a web server is like a connection.
Such as??????
Web browser: A software application for retrieving, presenting and traversing information resources on the World Wide Web.
example: Internet Explorer, Mozilla Firefox, Google Chrome
Web server: a program on a server computer, somewhere out on the internet, that delivers web pages to web browser.
A web browser is an application software with help of which you can surf (browse) to web . a web server is a software application usually installed on a more powerful computer and is used to serve or show web contents to users who are surfing web with web browser.
A domain host "hosts" you as you start up your own website. It ensures a stable connection, a wide network of visitors, security, access to up-to-date technologies, and storage.

What is the purpose of a file server?
A file-server is essentially a computer with a HUGE hard-drive, masses of RAM and one or more super-fast processors - which is connected to all the other computers on the network. It not only stores programs and data, but also communicates with the computers, printers, plotters and other hardware on the network.
What are the benefits of using a proxy server?
The benefits of using a proxy server are that data can be exchanged remotely without a direct connection, his means that one's internet address remains private. Proxies can also be used to control access to certain websites by allowing or blocking them.
Difference between a web server and a database server?
Application server is used to serve the logic of the business to the application with the help of different protocol whereas web server is used to handle HTTP requests.
An application server is a computer that stores application programs designed to be run, as services, from a client computer. Depending on the application design, a client computer can run or invoke the remote application via a web interface or by running a client program designed to work with the application program.
A web server is a program (or application program) that receives requests from Web Browsers and responds by sending data back to the browser where it is displayed as a web page.
How do you add MySQL to your Web server?
Linux variant: depending on the distribution you use, there are (most certainly) prepared packages (e.g. Debian, Ubuntu) to install, if you use a more complicated distro like gentoo, you have to download and compile the source packages (check google for tutorials on that).
Windows variant 1: you can employ a prepared WAMPP package (apache, mysql, php, pear/pecl) - find it here: www.apachefriends.org
Windows variant 2: you can install all desired services manually (check google for tutorials on windows apache iis)
What is IIS internet information server?
IIS is an abbreviation for Internet Information Services (formerly Internet Information Server.) It's Microsoft's web server that operates in WindowsNT and 2000, giving Windows HTTP capability. Short for Internet Information Server, Microsoft's Web server that runs on Windows NT platforms. In fact, IIS comes bundled with Windows NT 4.0. Because IIS is tightly integrated with the operating system, it is relatively easy to administer. However, currently IIS is available only for the Windows NT platform, whereas Netscape's Web servers run on all major platforms, including Windows NT, OS/2 and UNIX.
First of all, in a simple term, to answer any your queries/requests made by user through the web. Hence, the name 'Web Server'. A 'Server' is an application which is made available to listen to any request. A Server has the information. A Client is anyone who is in need of an information. When you say, you make a request via web (or over web), that means, through the WWW which is predominantly through HTTP. HTTP Stands for Hyper Text Transfer Protocol which defines the set of rules to be followed during the transcation over web. In an Web or Enterprise Application perspective, you need a webserver as a first entry point since all the requests have to be originated from a single place. Say, your login page to the application. But processing the login operation may not be the job of a Web Server and it would be done by a Web Application. As such, a Web Server is preferred to serve any static files, which is not changing in nature for any type of requests. Whereas, you need a Web application to produce a dynamic response according to the type of inputs you provide along with your request. In this scenario, to regulate all your traffic of requests, you need a single point of control, which is your webserver. Cheers, Raghavan alias Saravanan M.
Can you password protect documents on Google Docs?
Google doesn't give this feature directly but there are apps such as Innovode Armor that can password protect files and documents. Alternatively to password protect a google spreadsheet you can use google scripts.
Using scripting there are two options - encrypt and decrypt. You need to set a password first. Once you encrypt, all the text will be obfuscated and unreadable. To read it, you need to decrypt it again with the same password.
What is difference between client server and web server?
client site program always execute on client computer while server site program execute on sever computer
Difference between ado and ado.net?
ADO is a com base library that supports only connected data. This means that when we access the data (view, edit and update) it is affected in real-time,since the connection is being used all the time. ADO uses the objects as reference data known as Recordset object. Hence it basically gives a single table view of the data. We can also join tables to create a new set of records in ADO.ADO allows to create only client-side cursors. Using ADO we can persist records in XML format and XML integration is not possible.
ADO.NET is a CLR based library that supports disconnected recordsets. This means that When we access data, ADO.NET makes a copy of the data using XML and holds the connection to pull down the data or to make any requested updates as long as we need. The best method to follow is ADO.NET.ADO.NET uses various objects known as Dataset that allow to access data in various methods. Hence it allows to store the relational model of the database and helps us to access /update the data in each related table individually. ADO.NET supports both client-side and server-side cursors. Also the cursors are handled as classes in ADO.NET providing a way to create efficient applications. Using ADO.NET we can manupulate records in XML format. Also ADO.NET 2.0 provides Multiple Active ResultSets (MARS) which allows to have two datareader on one connection open at sametime.

What is logical communication?
By "logical" communication, we mean that although the communicating application processes are notphysicallyconnected to each other (indeed, they may be on different sides of the planet, connected via numerous routers and a wide range of link types), from the applications' viewpoint, it is as if they were physically connected.ahk
What are the disadvantages of ISDN?
VOIP has become a force to reckon with in the telecom sector with many people and businesses saving considerable time and resources by opting for a relatively inexpensive voice over internet protocol . VOIP has many advantages , follow here:
- The main advantage is the amount of money you end up saving on your phone bills as compared to a traditional phone line.
- Inexpensive and easy to use. Since it is simple, upgrading is relatively simpler too.
- You can integrate it with an existing phone connection.
- With VOIP PC-to-PC, calls are free no matter the distance and PC-to-Phone charges are nominal.
- For a monthly fee you may make unlimited free calls within a geographic area.
A virtual number enables you to make calls from anywhere as long as a broadband connection is available.
- You may purchase a number in a geography area of your choice, which works out very cheap.
-You may access your VOIP account just like your email Id from any where in the world as long as you have an internet phone. This makes it easy for those who travel frequently to make calls frequently to those back at home at local call rates, no matter where they are.
- You may call or message or do both at the same time with VOIP services.
- VOIP cost about half the cost of traditional phone services and it seems that the taxes and surcharges are much lower. Also your bill is easier to understand and it can be viewed via the Internet.
How many servers on the internet?
Hundreds of thousands. There is no way to get an accurate number. There are only a few really huge servers out there such as those run by AT&T, etc.
The World Wide Web (the Web, WWW, or W3) is a system of universally accepted standards for storing, retrieving, formatting, and displaying information via a client/server architecture. The Web handles all types of digital information, including text, hypermedia, graphics, and sound.

Difference between server web server?
Webserver: A Web server handles the HTTP protocol. When the Web server receives an HTTP request it responds with an HTTP response such as sending back an HTML page. To process a request a Web server may respond with a static HTML page or image send a redirect or delegate the dynamic response generation to some other program such as CGI scripts JSPs (JavaServer Pages) servlets ASPs (Active Server Pages) server-side JavaScripts or some other server-side technology. Whatever their purpose such server-side programs generate a response most often in HTML for viewing in a Web browser. Application Server: As for the application server according to our definition an application server exposes business logic to client applications through various protocols possibly including HTTP. While a Web server mainly deals with sending HTML for display in a Web browser an application server provides access to business logic for use by client application programs. The application program can use this logic just as it would call a method on an object
What are the main advantages of a Web Server Application?
A web server can actually mean one of two different things, either the actual computer hardware, or the software that runs on the web server, receiving requests from clients and responding to them. At first glance, the specifications of a web server may be very similar to the type of computer used as a desktop machine by many people, and in fact most desktop machines could be used as a server, given the right software. Like desktop machines, a server will have a CPU, RAM, a hard drive and an Internet connection. However, when you look more closely at these specifications, the differences become apparent. The speed of the CPU is less important in a server, as servers do not have high-end graphics requirements. Nowadays, it is becoming common to see two or more CPUs, rather than one faster CPU. Memory sizes tend to be similar to those of desktop machines, depending on the purpose for which the server is intended. Most servers will have more than one hard drive, which allows for a RAID set-up to be used for data integrity, and the hard drives will also tend to be larger than those used in a typical desktop machine. Servers may also have more than one power supply. Bear in mind that all of these components will normally be built to a higher standard, as reliability is important.
