Email

SMTP , POP3 & IMAP• SMTP : it’s a protocol for sending mail message between servers. Most e-

mail system that send mail over the internet use SMTP to send message from one server to another

• POP :Post Office Protocol download all mail from the server from the inbox and stores in computer. Email are removed from the server. Email are available when internet is not connected.

• IMAP : It’ stands for internet message access protocol. Email stay on the server and we can make and view mail folder on the server addition to the inbox. Since email stay on the server we can see all mail from many client program or device.

Email

How does Email works

Email

• After composing a message and hitting send, email client whether it's Outlook Express or Gmail - connects to domain's SMTP server

• email client communicates to the SMTP server, giving it email address, the recipient's email address

• The SMTP server processes the recipient's email address - especially its domain. If the domain name is the same as the sender's, the message is routed directly over to the domain's POP3 or IMAP server - no routing between servers is needed.

• If the domain is different, though, the SMTP server will have to communicate with the other domain's server

How does Email works

Email

• DNS takes the recipient's email domain name and translates it into an IP address

• SMTP server has the recipient's IP address, it can connect to its SMTP server. The message is routed along a series of unrelated SMTP servers until it arrives at its destination

• The recipient's SMTP server scans the incoming message. If it recognizes the domain and the user name, it forwards the message along to the domain's POP3 or IMAP server.

ATM

Back end process of an ATM• An ATM machine is a data terminal equipment(DTE) which converts user

information into signals or reconverts received signals.• These signals are processed via a standard telephone line using a toll free number

or via Ethernet connection using the internet service(advanced option)• PIN number of the customer and the Terminal Id number(TID) connects the ATM

network via which carried to the host processor or card holders bank• What is an ATM network? If you take your ATM card out of your wallet now, you

will see network logos (also known as bugs) on the back: • On receipt of the request, host banks application will send the desired results

asked by the user after validation of the request• The bank application will also call the API url used as an SMS gateway• http://sms.XXXX.in:8080/smart/SmartSendSMS.jsp?

Chat“ Real-time communication between two or more users via computer or mobile. Once a chat has been initiated, either user can enter text by typing on the keyboard and the entered text will appear on the other user's monitor. Most networks and online services offer a chat feature.”

CHAT

• Computers & mobiles make it hard to be a hermit.

• There are thousands of users engaged in friendly chats over the Internet.

• There are six types of IM clients, including single-protocol, multi-protocol, web-based, enterprise, mobile app and portable IMs. Regardless of which type you choose, they all connect the same way.

CHAT

• For a member of the IM network, the server will send your buddy list data

• The data sent to your computer is sent in multiple units called packets, smaller bits of information which leave the network server are received by your IM client. The data is then collected, organized and presented as live and offline friends on your contacts list.

• From this point, the collection and distribution of information between your computer and the network's server is continuous, open and instantaneous, making the lightning-quick speed and convenience of instant messaging possible.

CHAT

• Sending an instant message seems like a breeze

• Double-clicking a contact's screen name tells the client software to produce an IM window, addressed to that particular user

• Behind the screen, the client rapidly breaks up your message into packets, which are delivered directly to the recipient on their computer or device. As you chat with your contact, the window appears identically to both parties, and messages appear within a split second of being sent.

CHAT

• Once you are offline the server will stop incoming data packets from being transmitted to your computer or device. The network also updates your availability to offline on the buddy lists of friends, family and colleagues

• Incoming messages which were not received are stored as offline messages on most IM clients, and will be received when you sign back into the service

CHAT

SKYPE

What is video conferencing ?• Interactive telecommunication technology

• conference between two or more participants at different sites by transmitting audio and video data

• tools : video camera , microphone , speakers on device

6. Incoming calls from anyoneSKYPE

How does Skype works ? • The technique for making a phone call using the Internet is

referred to as Voice over Internet Protocol (VoIP), because it uses TCP/IP for delivering voice information

• The call uses TCP/IP to travel over the local network, then through the Internet, and then finally goes to the normal phone network closest to the call location

SKYPE

How VoIP (Voice over Internet Protocol) Works

• The VoIP phone converts the voice signal to digital data and compresses it .

• The compresses digitized voice signal is broken into IP packets.• The packets are sent out across the internet the same as any other

IP packets , using the internet TCP/IP Protocol• The voice packets are sent to an IP voice gateway nearest to the

phone call's destination. The IP voice gateway takes the voice packets converts them back into original form and sends them to the Public switched telephone network (PSTN)

• The call goes through PSTN , the call is sent to the IP gateway , which compresses it breaks into packets sends it over to the internet to the caller

Payment Gateway

PAYMENT GATEWAY

Definition• The service that automates the payment transaction between the

shopper and merchant. It is usually a third-party service that is actually a system of computer processes that process, verify, and accept or decline online transactions on behalf of the merchant through secure Internet connections.

• The payment gateway is the infrastructure that allows a merchant to accept credit card and other forms of electronic payment. When referring to payment gateways used for Internet transactions, it may also be called an IP payment gateway.

• A payment gateway facilitates the transfer of information between a payment portal (such as a website, mobile phone or interactive voice response service) and the Front End Processor or acquiring bank

PAYMENT GATEWAY

How Payment Gateway Works

Functions of Payment Gateway.• Authorizing- Verifying the Buyer’s Credit/debit card details.• Clearing- Transferring the transaction to merchant’s bank.• Reporting- Recording all transaction.

Steps Involved in Payment Gateway Transaction

• Step1:- When clicks on the “Buy” button. A message is sent to the website regarding the consumer’s desire to buy and make payment.

• Step 2:- Once message is received by web store server, adds its digital

certificate. Message is now called a “Digital Order” and also includes the consumer’s IP address and transaction amount. Digital Order is now sent to the Payment Gateway

• Step 3:-Based on the Digital Certificate, the Payment Gateway authenticates the web store.

• Step 4:- The Payment Gateway offers various payment options on a screen to the buyer.

PAYMENT GATEWAY

• Step 5:- Buyer chooses the desired payment option, which is transmitted via the secure link to the Payment Gateway.

• Step 6 - The Payment Gateway sends the payment details to the acquiring bank

• Step 7 - The acquiring bank sends the information to the buyer’s issuing bank.

• Step 8 - Based on the credit limit and the payment instrument’s validity, the issuing bank either accepts or rejects the transaction. The confirmation/rejection message is transmitted to the Payment Gateway through the acquiring bank.

• Step 9 - The Payment Gateway then transmits digital receipts to the shopping site as well as the buyer.

• Step 10- The web store can ship the goods/services to the buyer.

PAYMENT GATEWAY

Benefits of Payment Gateway• 24X7X365 Convenience.• Real time Authorization of Credit/debit cards.• Multiple payment Option.• Flexible, powerful real-time reports generation • Multi currency settlement.• Facility for customer refund.• Stringent security measures to gain customer & merchant trust.
