http://www.learning-tutorials.blogspot.com



1)Gmail doesn't recognize dots as characters within a username.It means if your e-mail address is username@gmail.com, then user.name@gmail.com and u.s.e.r.n.a.m.e@gmail.com are also yours.




2)If you send messages and immediately archive the conversation, you can save yourself  by adding a Send & Archive button.For this you have to follow the steps .

             a)Open gmail account
             b)Go to Setting
             c)Go to Labs
             d)Enable Send and Archive button
             e)click save changes


3)Gmail doesn't offer traditional e-mail aliases(other name), but you can add a "+" to the end of your username to create it. For example, messages sent to username+alias@gmail.com is sent to username@gmail.com. This can be useful for setting up filters or figuring out who's selling your e-mail address to spammers. 





4)You cannot attach an executable file like a normal file. Gmail will display the error message – “FILE is an executable file. For security reasons, Gmail does not allow you to send this type of file”.
To overcome this issue, do the following as a sender of the email.

  a)Rename the file without an exe extension,
  b)Compress it with any compression utility and then attach it.

Now it will get attached, and uploaded successfully. The receiver of the email should uncompress the attachment and rename it again with exe extension.




5)If you want to search something in Gmail than you can easily search by simply type the syntax in Gmail search box.
Syntax is:

Types of messages in Gmail
  • Starred - messages which are Considered as an important
  • Unread - messages which are unread
  • read - messages which are read
  • chat - Conversation messages
“is:starred”, “is:unread”, “is:read” and “is:chat” will search for the messages that are starred, unread, read and chat messages respectively.

For Example, the following will give you the list of starred messages in Inbox folder.
in:inbox is:starred




7)Gmail provides feature to import the contacts from Yahoo, Orkut and Outlook. You can also import contacts from CSV(Comma Seperated Value)file. CSV file should be formatted as a table and must include a header that defines the fields in your table. Gmail accepts many common header fields (Firstname, Lastname, email address, Phone etc.)

                 c)Click on “Import” tab
                 d) Browse the CSV file which you want to import
                 e)Click on “Import”  



8)If you have multiple Gmail accounts than you can manage those account in your one account,means you can send mail by other account by being present in the current account.

Follow the steps below to send emails from other accounts. i.e From x@gmail.com, you can send emails as y@gmail.com

  2. Add y@gmail.com account here and confirm that this is your email by following the instruction.
  3. Now you can start sending emails as y@gmail.com from x@gmail.com


9) If you have a doubt that somebody else is accessing and hacking into your Gmail account, Gmail provides ‘Last Account Activity’ feature that shows five recent activities in your Gmail account.
Click on ‘Details’ link in Last account activity line at the bottom of your Gmail page.
Recent activity information includes, Access Type (Browser or from some mobile device etc), IP address from which the access was made and Date/Time of access.

    13)Gmail handily saves your chat history for conversations with other Gmail users and makes them searchable too (use the search term “is:chat” to look for a keyword term). But there might be times you want to chat and not have it recorded.
    To chat “off the record,” open a chat window with whom you want to talk, click on the “Actions” drop down menu and select “Go off the record.” The person you’re chatting with will be notified of this change.



    14)You can access your Gmail account when you’re not connected(offline) to the web.

    What Is Email Protocol?





    Hello friends as you know that email protocol is a method by which a communication channel is established between two computers and email is transferred between them. When an email is transferred, a mail server and two computers are involved. One computer sends the mail and the other one receives it. The mail server stores the mail and lets the receiving device access it and download it if needed. There are four different mail protocols.




    1)POP3 (Post Office Protocol 3):-

    This is a simple, standardized protocol that allows users to access their mailboxes on the Internet and download messages to their computers. The simple design of POP3 allows casual email users who have a temporary Internet connection (dial-up access) to access emails. They can read their emails, draft new emails or reply to emails while they are offline, and can send these emails when they are back online. Yahoo! Mail (mail.yahoo.com) is an example of a mail server that uses POP3 protocol.




    2)IMAP (Internet Message Access Protocol):-

    This is a standard protocol used for email transfer by users. Like POP3, it also supports both online and offline modes of email access. The email message is downloaded to the user's machine only when a specific request is made to read it. Users can download mails to their computers while keeping a copy on the server. The mails on the server are the primary copy and anything changed on the local machine is updated by what is on the server.Users can also create new mailboxes which are shown as folders on the server, and move messages between folders. This feature allows access to shared and public folders.Gmail is an example of a mail server which uses IMAP protocol.




    3)SMTP (Simple Mail Transfer Protocol):-
    SMTP is a simple, text-based protocol that works best when devices are interconnected to each other. However, SMTP protocol can only be used to send emails. Unlike POP3 and IMAP protocols, SMTP does not provide the functionality to the users to retrieve emails from the server.One of the main issues with SMTP is the lack of sender email authentication. SMTP lacks security features too and thus users get spam emails.UNIX systems and simple applications like "mailsend" make use of SMTP protocol.

    4)HTTP (Hyper Text Transfer Protocol):-

     HTTP is not used exclusively for mail transfer, but it plays a vital part for users who use Internet browsers for accessing their mails (both for sending and receiving).Hotmail and Yahoo! use HTTP protocol for accessing emails through the Internet.







     Thanks Friends....

    Google Tips And Tricks

    Hello friends today i'm disscussing some most important google tricks and tips,these tips really helps you,when you search anything online.So don't waste your time and try to implement this:):)







    1)Google's main search invisibly combines search terms with the Boolean construct "AND". When you enter computer world – it looks for computer AND world


    2)To make Google search for computer or world, just type computer OR world,(Instead of OR you can type the | symbol, like this: computer | world)

    3)Boolean connectors like AND and OR are case sensitive. They must be upper case.

    4)Search for a specific term, then one keyword OR another by grouping them with parentheses, like this: near(computer OR world)

    5)To look for phrases, put them in quotes: "there's no school without students"

    6)Exclude specific key words with the minus operator. new -amazon excludes all results from amazon.


    7)The plus operator makes sure stop words are included. Like: fish +and chips

    8)You can also ask Google to fill in a blank. Try: Christopher Columbus discovered

    9)Search for a numerical range using the numrange operator. For example, search for Sony TV between £300 and £500 with the string Sony TV £300..£500


    10)Search for any filetype directly using the modifier filetype:[filetype extension]. For example: soccer filetype:pdf

    11)Google has some very powerful, hidden search parameters, too. For example "intitle" only searches page titles. Try intitle:herbs



    12)If you're looking for files rather than pages – give index of as the intitle: parameter. It helps you find web and FTP directories.


    13)The modifier inurl only searches the web address of a page: give inurl:spices

    14)Want to know how many links there are to a site? Try link:sitename – for example link:www.mozilla.org

    15)Similarly, you can find pages that Google thinks are related in content, using the related: modifier. Use it like this: related:www.microsoft.com


    16)The modifier info:site_name returns information about the specified page.

    17)Specify a site to search with the site: modifier – like this: search tips site:www.facebook.com


    18)Use the site: modifier when searching Google Images, at images.google.com. For example: dvd recorder site:www.amazon.co.uk



    19)Similarly, Google Blogsearch(blogsearch.google.com) has its own syntax. You can search for a blog title, for example, using inblogtitle:<keyword>


    20)The general search engine can get very specific indeed. Try movie:<name of film> to look for movie reviews.


    21)For a dedicated film search page, go to www.google.co.uk/movies


    22)Google really likes movies. Try typing director: The Dark Knight into the main search box.

    23)For cast lists, try cast: name_of_film


    24)There's also a built-in dictionary. Try define:<word> in the search box.

    25)Google stores the content of old sites. You can search this cache direct with the syntax keyword cache:site_url


    26)Synonym search looks for words that mean similar things. Use the tilde symbol before your keyword, like this: ~rain


    27)Looking for a map? Just add map to the end of your query, like this: Leeds map
