2. What is Skype? Skype may be the answer to a lot of things you've always wanted, but didn't know were possible. For example, a way to talk to family members in different parts of the country for free. A way to call people abroad (on their phones or cell phones) for less money. A way to be there for important life events when you can't be there in person. The service allows users to communicate with peers by voice using a microphone, video by using a webcam, and instant messaging over the Internet. Phone calls may be placed to recipients on the traditional telephone networks. Calls to other users within the Skype service are free of charge, while calls to landline telephones and mobile phones are charged via a debit-based user account system. Skype has also become popular for its additional features, including file transfer, and videoconferencing Skype explained visually.

3. Features and Services Registered users of Skype are identified by a unique Skype Name, and may be listed in the Skype directory. Skype allows these registered users to communicate through both instant messaging and voice chat. Voice chat allows telephone calls between pairs of users and conference calling, and uses a proprietary audio codec. Skype's text chat client allows group chats, emoticons, storing chat history and editing of previous messages. Offline messages were implemented in a beta of version 5, but removed after a few weeks without notification. The usual features familiar to instant messaging users — user profiles, online status indicators, and so on — are also included. Skype does not provide the ability to call emergency numbers such as 112 in Europe and 911 in North America. The U.S. Federal Communications Commission (FCC) has ruled that, for the purposes of section 255 of the Telecommunications Act, Skype is not an "interconnected VoIP provider".

4. Security and privacy Skype is claimed to be a secure communication; encryption cannot be disabled, and is invisible to the user. Skype reportedly uses publicly documented, widely trusted encryption techniques: RSA for key negotiation and the Advanced Encryption Standard to encrypt conversations. However, it is impossible to verify that these algorithms are used correctly, completely and at all times as there is no public review possible without a protocol specification and/or the program source code. Skype provides an uncontrolled registration system for users with no proof of identity. Instead, a free choice of nicknames permits users to use the system without revealing their identity to other users. It is trivial to set up an account using any name; the displayed caller's name is no guarantee of authenticity. A third party paper analyzing the security and methodology of Skype was presented at Black Hat Europe 2006. It analyzed Skype and found a number of security issues with the current security model. 13 November 2012, A Russian user published a flaw in Skype security which allowed any non-professional to take over Skype account knowing only victim's email with 7 simple steps. This vulnerability was claimed to exist for months, and existed for more than 12 hours since published widely

5. Contacts Who do you know on Skype? Maybe a friend or family member? It's time to add them to your contacts. Adding contacts (or importing them from services like Gmail or Facebook) is the first step towards actually using Skype - to call, chat, and video conference with the people you care about. To Add a Contact: 1.Open the Skype window and sign in. 2.Click the Add a contact button at the bottom of your Contacts tab. 3.The Add a contact window will appear. 4.Search for someone you know using their email, phone number, name, or Skype name. 5.Depending on what you entered, you may need to click Add to continue, or View to see a list of search results. 6.When you find the person you're looking for, click Send request to send them a contact request. 7.A page appears confirming that your contact request has been sent.

6. Safety tips It's important to know how to deal with unwanted callers on Skype, and how to protect yourself from spam, phishing, and other scams. The first step to safety is adjusting your privacy settings, so only the people you know can contact you. Blocking Contacts There are several reasons you may want to block someone on Skype. Perhaps the person is sending you spam, or phishing for personal information like your bank account number. On the other hand, you may someday need to block someone you know, for inappropriate behavior like cyber-harassment. You can always block or ignore suspicious contact requests as soon as you receive them. Or you can accept them (for example, if you think you might know the person), then block them later if you change your mind. All you have to do is right-click their name on the Contacts tab, and choose Block This Person from the list of options. When you block someone on Skype, you can also report them for abuse (spam, phishing, etc.) if the situation warrants it.

7. Spamming and Phishing • Instant Message Spam The word spam is often used to refer to junk email, or unwanted email advertisements. Unfortunately, you can receive spam in Skype, too - in the form of instant messages from people you don't know. Phishing scams and malware can even be included in spam, so it's important to know what to do when you receive a suspicious message on Skype. Never reply, or follow any links sent by a spammer. It can be tempting, but it will just confirm to them that you've read the message. They may think you're a good target for more spam - or for scams that are more harmful, because they involve your credit card or personal information. Phishing and other scams Many spammers aren't trying to sell you anything - they're trying to gain access to your information, or even steal money from your bank account. Scams come in many different forms, but they generally work by promising you something that's too good to be true, or by making you think something bad will happen if you don't take action. Phishing is a type of scam where someone pretends to be from a bank or another trusted source, in order to trick you into giving them your personal information. A phishing message will often have a sense of urgency; for example, it may claim that "unauthorized charges" were made on your credit card, and that you need to verify your information.

8. Calling Making Free Skype-to-Skype Calls As you know, calls to other people on Skype are free. The word for this type of call is Skype-to-Skype, meaning that you and the other person are both using Skype (not any other kind of phone or mobile device) to call each other. To Call Someone on Skype: Open the Skype window and sign in. Click the person you want to call on the Contactstab The contact's information will open in a pane on the right. Click the Callbutton. The call window will appear. You'll hear a ringing until the other person answers. Talk as long as you like. Click the End Call button when you're ready to hang up. Click here to watch a video.
