 Internet is also known as the World Wide Web (www) is a global system of interconnected computer networks that use a protocol called the Internet Protocol Suite (TCP/IP) to link to billions of devices all around the world. The impact of this has been so enormous that it has been referred to as the 8^th continent of the world. This carries a vast range of information, from the top-secret military and research files to the most trending and viral video of the week. This massive storage is shared by everyone, with everyone’s computer contributing to the ever-expanding treasure trove of knowledge.

The computer is an electronic device which takes input data from the user, then processes it and returns the required output data. Input and output data may contain numbers, words, pictures, videos or sounds. A computer can process data at a very high speed without making any mistake and has a huge storage capacity.

The five basic functions of a computer are as follows:

1. It receives input data from the user.
2. It processes the given data.
3. It produces an output.
4. It stores the result.
5. It controls all the above operations.

Both the Bar and the Column charts display data using rectangular bars where the length of the bar is proportional to the data value. Both are used to compare two or more values. However, their difference lies in their orientation. A Bar chart is oriented horizontally whereas the Column chart is oriented vertically.

The OSI Model (Open Systems Interconnection Model) is a conceptual framework used to describe the functions of a networking system. The OSI model characterizes computing functions into a universal set of rules and requirements in order to support interoperability between different products and software. In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

A recurring appointment repeats on a regular basis (for example, every Tuesday). This is different from a recurring meeting, which involves inviting individuals. Open your calendar. Click on New Appointment or double click on a desired date and time in your calendar to open a new Appointment window.

Word wrapping is when a line of text automatically "wraps" to the next line when it gets to the end of a page or text field. This is different than a "word rap," which involves rhyming words to a rhythmic beat, though that may be more fun than typing. Most word processing programs use word wrap to keep the text within the default margins of the page. Without the word wrap feature, text would continue on one line until the user pressed "Enter" or "Return" to insert a line break.

Most programs that incorporate word wrap take the first word that does not fit on a line of text and move it to the beginning of the next line. Advanced word processing programs can hyphenate long words at appropriate places. While it is uncommon, sometimes a word, or string of characters ,will take up more than one line. In this case, the word wrap feature will simply continue the string of characters onto the next line.

 P2P stands for "Peer to Peer." In aP2P network, the "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server. In other words, each computer on a P2P network becomes a file server as well as a client.
