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.

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

28)Google finds images just as easily and lists them at the top, when you add image to the end of your search.

29)What time is it? Find out anywhere by typing time then the name of a place.

30)You can invoke the spell checker directly by using spell: followed by your keyword.

31)Click "I'm Feeling Lucky" to be taken straight to the first page Google finds for your keyword.

32)Want to see what others are searching for or improve your page rank? Go to www.google.com/zeitgeist

IPV6 Launched

Hello friends on june 6,2012 microsoft launched IPv6.Now microsoft supports industry-standard technologies including the new standard protocol for the Internet, Internet Protocol version 6 (also known as IPv6), which is the next step beyond IPv4, the current standard protocol for the Internet. These protocols provide IP addresses, the "phone numbers" for the Internet that are responsible for identifying computers and devices so that they can communicate.
IPv6 is designed to solve many of the problems of IPv4, including mobility, auto-configuration, and overall extensibility. IPv6 expands the address space on the Internet and supports a nearly unlimited number of devices that can be directly connected to the Internet.




Differences between address space of IPv4 & IPv6:-

An IPv4 address is represented by 4 groups of 8-bit decimal values separated by dot(.),For example:-

An IPv6 address is represented by 8 groups of 16-bit hexadecimal values separated by colon(:)and it is abbrviated with the  following rules:

• Omit leading zeroes in a 16-bit value.
• Replace one or more groups of consecutive zeroes by a double colon.

 1) While logged onto the computer that has administrative rights, click on Start->Run->Type cmd


2) In The command prompt window,type net users (This will show you every account that is made onto the computer whether it is hidden or not. )



3)After netuser write the name of the account then * and press enter. heres an example: net user administrator * or net user "computer world" *(Put the name in quotes if it contains spaces)




4) From there it should ask for a new password. Type in your new password (type very carefully - the command window won't display what you type) and once more to confirm it. If you get the message that the command succeeded successfully you're all set!!

How To Speed Up Internet By 20%?

Friends Microsoft reserves 20% of your available bandwidth for their own purposes like Windows Updates and interrogating your PC,You can get it back by following steps.


      Click Start then Run and type gpedit.msc without quotes. This opens the group policy editor.

    Then go to:-

          ->Local Computer Policy
       ->Computer Configuration
       ->Administrative Templates
       ->Network      
       ->QOS Packet Scheduler 
       ->Limit Reservable Bandwidth.


       Double click on Limit Reservable bandwidth It will say it is not configured, but the truth is that by default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a
connection, but you can use this setting to override default  So the trick is to ENABLE reservable bandwidth, then set it to
ZERO. This will allow the system to reserve nothing, rather than the default 20%.

Why Can We Not Ping Microsoft.com, Amazon.com, Or Other Site?

Hello Friends,Some popular sites such as amazon.com, microsoft.com, slashdot.org, and other sites that have had DoS attacks in the past may disable ICMP(Internet Control Message Protocol) on their servers and setup other network settings that prevent a ping request be received or responded to. Because of this when you ping these domain names or their associated IP addresses you'll receive a "Request timed out." or get a "100% packet loss."

How to create a CSV(Comma Seperated Value) file?

Friends, comma-separated values (CSV) file is any file containing text that is separated with a comma, but can also be a file separated with any other character. To create a CSV is as simple as creating any text file and can be created in any text editor, however, is often created in a spreadsheet program such as Microsoft Excel. Below are the steps on how to create a CSV file using a text editor such as Notepad.

To create a CSV file in a text editor open a new text editor program, such as Notepad. Once open write the text you wish the file to contain and separate each field or column of data with a comma and each row with a new line.

Therefore, the above data if opened in a spreadsheet program such as Microsoft Excel would create a table similar to the below example.

Title4	Title5	Title6
one	two	three
example1	example2	example3
