Web Servers

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.

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.

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)

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.

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.

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

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.

A web server responds to requests for files and sends them to the computer that requested them.

A web browser is a user agent that asks a web server for files. canyou take apart the fuel gauge on a 2004 Harley Wide Glide

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

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.

The TCP/IP service that lets you check to verify that you can reach another network node from your local host. Ping is usually a quick test to ensure that your connection is valid. The command will return the time in milliseconds that a packet takes to make the round trip from your local host to the remote host.

The primary function of the Web Server is to send and receive text-based messages containing requests and replies.
