E-books and E-readers, digital books and digital readers
http://en.wikipedia.org/wiki/Comparison_of_e-book_readers
An electronic book (also e-book, ebook digital book) is a publication of a complete book in digital form. It consists of text, images, or both. E-books are produced on, published through and readable on computers or other electronic devices.
E-books can be read on computers, cell phones or e-book readers.
An e-book reader is a portable electronic device that is designed to enable people to read digital books and magazines. It looks like a tablet computer, but has readability of their screens, especially in sunlight. It also has longer battery life than a tablet.
E-readers use electronic paper which is more comfortable to read than the screens of computers. This is due to the stable image, which has no need to be refreshed constantly, a wider viewing angle, and that it reflects ambient light rather than emitting its own light. An ideal e-paper display can be read in direct sunlight without the image appearing to fade.
Any device that can display text on a screen can act as an e-book reader, but without the advantages of the e-paper technology.

Netbook
What's the difference between notebooks, netbooks and ultra-mobile PCs?
http://computer.howstuffworks.com/notebook-vs-netbook-vs-ultra-mobile-pc.htm
Laptop computers, notebooks and netbooks use the same basic form (a screen and a keyboard attached by hinges), but differ in size. Netbook computers are smaller and lighter than notebook computers, which, again, are smaller and lighter than laptops.
Netbook computers are relative newcomers to the computer market. The general definition for a netbook computer is that they are smaller, less powerful and less expensive than notebook computers.
As the Web takes a more leading role in computing, the processing requirements for consumer computers become less demanding.
Nets and CloudsNetbooks and cloud computing go hand-in-hand. A cloud computing network is a collection of servers that provides data storage and processing power over the Internet. Ideally, a cloud computing service eliminates the need for an expensive, powerful personal computer. The machines on the Internet do all the hard work for you.
Tablet computer
http://en.wikipedia.org/wiki/Tablet_personal_computer
A tablet PC is a laptop computer, equipped with a touch screen that can be rotated. The screen is therefore an additional input device. The tablet runs a standard PC operating system like Windows or Linux.
Tablet PCs are pen-based, with handwriting and voice recognition functionality. Tablet PCs use the same hardware as normal laptops but add support for pen input.
Support is built into both Home and Business versions of Windows Vista and Windows 7. Tablets running Windows get can also use the touch screen for mouse input, hand writing recognition, and gesture support.
Microsoft Surface(above) is a multi-touch product from Microsoft which is developed as a software and hardware combination technology that allows a user, or multiple users, to manipulate digital content by the use of gesture recognition. This could involve the motion of hands or physical objects.
Targeted customers are in the hospitality businesses, such as restaurants, hotels, retail, public entertainment venues and the military for tactical overviews It can also be seen in the CSI-television series.
Social networking
en.wikipedia.org/wiki/Social network
Social networking is the grouping of individuals into specific groups. Social networking is possible in person, but especially in the workplace, universities, and high schools, it is more popular online. This is because the internet is filled with millions of individuals who are looking to meet other people, to gather and share first-hand information and experiences about cooking, golfing, gardening, developing friendships or professional alliances, finding employment, business-to-business marketing, etc.
Participants are mostly adolescents, college age, or young adult professionals. Studies also show that teenagers capture and produce their own media, and stay in constant contact with each other using mobile devices. Usually while doing this they are also using other forms of media such as music or video content via their iPods or other similar devices. This has led social scientists to believe that learning and multitasking will have a new face in the future.
When it comes to online social networking, websites are commonly used. These websites are known as social sites.
Benefits: the friends that you can make, diversity, learn about new cultures or new languages.
BUT, as I'm sure you're aware, there are dangers associated with social networking, such as data theft and viruses, online predators or individuals who claim to be someone that they are not. Just like you're advised when meeting strangers at clubs and bars, school, or work -- you are also advised to proceed with caution online.
By being aware of your cyber-surroundings and who you are talking to, you should be able to safely enjoy social networking online
Examples are: MySpace, FriendWise, FriendFinder, Yahoo! 360, Facebook, Orkut, and Classmates.
YouTube
YouTube is a website on which users can upload, share and view videos. It uses Adobe Flash Video and HTML5 technology to display a wide variety of videos created by internet users, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos.
Unregistered users may watch videos, and registered users may upload an unlimited number of videos.
In 2006 YouTube was bought by Google Inc. for $1.65 billion, and now operates as a subsidiary of Google.
YouTube was founded by(from left to right)Chad Hurley, Steve Chen, and Jawed Karim.
Facebook is a social networking service and website .In January 2011, Facebook had more than 600million active users.
Users may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Facebook users must register before using the site. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics. Facebook allows any users who declare themselves to be at least 13 years old to become registered users of the website.
The name of the service is derived from the name given to the book students receive at the start of the academic year by university administrations in the United States to help students get to know each other better.
Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes in his room at Harvard University.
"LinkedIn is the office, Facebook is the barbecue in the backyard, and MySpace is the bar," says Hoffman, referring to the three major social-networking sites battling it out for millions of consumers and billions of dollars in online ads.

http://personalweb.about.com/od/myspacecom/a/whatismyspace.htm

· Advanced Editing: you can use HTML and JavaScript in your MySpace editor.
· Keep In Touch: email, blogs, IM, forums, bulletins and groups
Disadvantages:
· Editor Mishaps: The MySpace blog offers ways to change the colors, backgrounds and other things but you need to know the codes to enter to do it.
· Anyone Can Contact You: MySpace offers no way to allow people to see your profile but still keep them from emailing your and trying to add you to their own MySpace friend list.
· Options Are Hard To Find: There are many things you can do on your MySpace profile that are not obvious. Creating a MySpace slideshow, adding HTML templates. You will see some pretty amazing things on some of the MySpace profiles and you may wonder how they are done because MySpace doesn't tell you.
LinkedIn is a business-oriented social networking site mainly used for professional networking. LinkedIn has more than 60 million registered users, spanning more than 200 countries and territories worldwide.
The site is available in English, French, German, Italian, Portuguese, Spanish, Romanian, Russian and Turkish
LinkedIn's CEO is Jeff Weiner, previously a Yahoo! Inc .executive. The company was founded by Reid Hoffman and team members.
One purpose of the site is to allow registered users to maintain a list of contact details of people with whom they have some level of relationship, called Connections. Users can invite anyone (whether a site user or not) to become a connection.
This list of connections can then be used in a number of ways:
ë A contact network is built up consisting of their direct connections. It can then be used to find jobs, people and business opportunities recommended by someone in one's contact network.
ë Employers can list jobs and search for potential candidates.
ë Job seekers can review the profile of hiring managers and discover which of their existing contacts can introduce them.
ë Users can post their own photos and view photos of others to aid in identification.
ë Users can now follow different companies and can get notification about the new joining and offers available.
ë Users can save (i.e. bookmark) jobs which they would like to apply for.
ë The "gated-access approach" (where contact with any professional requires either a preexisting relationship, or the intervention of a contact of theirs) is intended to build trust among the service's users.
ë LinkedIn also allows users to research companies with which they may be interested in working. When typing the name of a given company in the search box, statistics about the company are provided
ë In January 2011, LinkedIn acquired CardMunch, a mobile app maker that scans business cards and converts into contacts. LinkedIn plans to integrate this functionality into their services in the near future.

Foursquare
Foursquare is a social networking website based on software for mobile devices that allows registered users to connect with friends and update their location. This service is available to users with GPS-enabled mobile devices such as smart phones. Users "check-in "at venues using a mobile website, text messaging or a device-specific application.

Online auction and shopping sites
eBay
...is an online auction and shopping website on which people and businesses buy and sell a broad variety of goods and services worldwide. eBay is one of the success stories of the dot-com bubble with operations in over thirty countries.
One of the first items sold on eBay was a broken laser pointer for $14.83. Astonished, Omidyar contacted the winning bidder to ask if he understood that the laser pointer was broken. In his responding email, the buyer explained: "I'm a collector of broken laser pointers."
Bid or Buy
...is South Africa's largest internet auction website, run by bidorbuy (Pty) Ltd.
Gum Tree
Gumtree is a network of online classified advertisements and community websites. Classified ads are either free or paid for depending on the product category and the market.
Sellers may place their ads on the homepage or under product categories. Gumtree now covers 60 cities across 6 countries- the UK, Ireland, Poland, Australia New Zealand and South Africa. It is the UK's largest website for local community classifieds.
Unfortunately Gumtree has been used by fraudsters to place ads scamming people out of thousands of rands. In South Africa, for example, non-existent holiday accommodation was advertised. A deposit was paid, but the holiday makers could not find the house they were supposed to have rented.
