What is TCP/IP?

TCP/IP stands for Transmission Control Protocol / Internet Protocol. It defines how electronic devices (like computers) should be connected over the Internet, and how data should be transmitted between them.
TCP - Transmission Control Protocol
TCP is responsible for breaking data down into small packets before they can be set over a network, and for assembling the packets again when they arrive.
IP - Internet Protocol
IP takes care of the communication between computers. It is responsible for addressing, sending and receiving the data packets over the Internet.

IP is Connection-Less

TCP/IP Protocol for WEB

Web browsers and servers use TCP/IP protocols to connect to the Internet. Common TCP/IP protocols are:
HTTP - Hyper Text Transfer Protocol
HTTP takes care of the communication between a web server and a web browser. HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.
HTTPS - Secure HTTP
HTTPS takes care of secure communication between a web server and a web browser. HTTPS typically handles credit card transactions and other sensitive data.
FTP - File Transfer Protocol
FTP takes care of transmission of files between computers.

Domain Names

A name is much easier to remember than a 12 digit number.
Names used for TCP/IP addresses are called domain names.

TCP/IP Protocols for Email

E-mail programs use TCP/IP for sending and receiving e-mails. The TCP/IP protocols for email are:
SMTP - Simple Mail Transfer Protocol
 SMTP takes care of sending emails. Often emails are sent to an email server (SMTP server), then to other servers, and finally to its destination. SMTP can only transmit pure text. It cannot transmit binary data like pictures, sounds or movies.
MIME - Multi-purpose Internet Mail Extensions
The MIME protocol lets SMTP transmit multimedia files including voice, audio, and binary data across TCP/IP networks. The MIME protocol converts binary data to pure text, before it is sent.
POP - Post Office Protocol
The POP protocol is used by email programs to retrieve emails from an email server. If your email program uses POP, all your emails are downloaded to your email program (also called email client), each time it connects to your email server.
IMAP - Internet Message Access Protocol
The IMAP protocol works much like the POP protocol. The main difference is that the IMAP protocol will not automatically download all your emails each time your email program connects to your email server.
The IMAP protocol allows you to look through your email messages at the email server before you download them. With IMAP you can choose to download your messages or just delete them. This way IMAP is perfect if you need to connect to your email server from different locations, but only want to download your messages when you are back in your office.     

ASP.NET Web Forms

There are three kinds of server controls:

• HTML Server Controls - Traditional HTML tags
• Web Server Controls - New ASP.NET tags
• Validation Server Controls - For input validatio

ASP.NET - HTML Server Controls

HTML server controls are HTML tags understood by the server.
HTML elements in ASP.NET files are, by default, treated as text. To make these elements programmable, add a runat="server" attribute to the HTML element. This attribute indicates that the element should be treated as a server control. The id attribute is added to identify the server control. The id reference can be used to manipulate the server control at run time.

ASP.NET - Web Server Controls

Web server controls are special ASP.NET tags understood by the server.
Like HTML server controls, Web server controls are also created on the server and they require a runat="server" attribute to work. However, Web server controls do not necessarily map to any existing HTML elements and they may represent more complex elements.

ASP.NET - Validation Server Controls

Validation server controls are used to validate user-input. If the user-input does not pass validation, it will display an error message to the user.
Each validation control performs a specific type of validation (like validating against a specific value or a range of values).
By default, page validation is performed when a Button, ImageButton, or LinkButton control is clicked. You can prevent validation when a button control is clicked by setting the CausesValidation property to false.



All server controls must appear within a <form> tag, and the <form> tag must contain the runat="server" attribute.

Note: The form is always submitted to the page itself. If you specify an action attribute, it is ignored. If you omit the method attribute, it will be set to method="post" by default. Also, if you do not specify the name and id attributes, they are automatically assigned by ASP.NET.

Note: An .aspx page can only contain ONE <form runat="server"> control!

The ViewState indicates the status of the page when submitted to the server. The status is defined through a hidden field placed on each page with a <form runat="server"> control. 
Maintaining the ViewState is the default setting for ASP.NET Web Forms.If you want to NOT maintain the ViewState, include the directive <%@ Page EnableViewState="false" %> at the top of an .aspx page or add the attribute EnableViewState="false" to any control.

Hosting Websites on Google Drive

Almost everyone who owns a computer also owns at least one website these days. Be it personal or professional. There are a number of hosting services available on the web for us to host our websites but most of them cost money.  A simple and efficient way to host websites can be Google Drive. With its free storage space of up to 15 GB, you can host a fairly large website without any cost.

Google Drive can be used to host basic websites or even complex JavaScript-based web apps. You may publish any kind of static content on your website including HTML pages, images, CSS, icons, audio, video etc.
Note: However, Google Drive does not support web resources that make use of server-side scripting languages like PHP.
Here's how:
1)Create a public file folder.
2) Put your website i.e.the HTML, CSS, Javascript files inside it.
3)Open the HTML file and preview it.
4) Share the URL that looks like "www.googledrive.com/host/..." from the preview window.
To create a public folder:  For this, you simply need to go to folders, create a new folder, and rename it to whatever name you want. Following which, you select the checkbox next to the New folder. Click the "Sharing settings" icon. Then click "Change" and make your folder "Public on the web".
