Communication is a process where we share our feelings, thoughts, experience, ideas, suggestions, feedback etc. In process of communication receiver, message, sender, feedback etc are some of the important elements which has their own role and meaning. Usually the process of communication will not end in our life. Communication can be categorized into three basic types: (1) verbal communication, in which you listen to a person to understand their meaning; (2) written communication, in which you read their meaning; and (3) nonverbal communication, in which you observe a person and infer meaning.

 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.

There are four main categories or communication styles including verbal, nonverbal, written and visual:

• Verbal. Verbal communication is the use of language to transfer information through speaking or sign language. ...
• Nonverbal. ...
• Written. ...
• Visual.

  Four main objectives of are:

• Communication creates awareness. 
• Communication allows advertising. 
• Communication allows protection of a certain idea or image in turn it allows people to shape their Attitudes based on ideas.
• Communication allows exchange of knowledge.

There are two types of software, i.e. system software and application software. Language processors (interpreters, compilers and assemblers), operating systems etc., are the examples of system software. Whereas, payroll system, accounting software etc., are the examples of an application software.

ARPANET was the network that became the basis for the Internet. The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switching network with distributed control and the first network to implement the TCP/IP protocol suite.

There are many advantages of using computers. However, the following are some of the most important ones to know:

1.Provides access to more information

2.Completes tasks that might be impossible for humans to complete

3.Saves time

4.Automates repetitive tasks

5.Allows for greater productivity

6.Allows for better communication and connections

7.Entertainment

Communication skills are those skills which are needed to speak and write properly. A person who is able to speak appropriately whilst maintaining eye contact with the audience, uses varied vocabulary and articulate speech to suit the need of the audience is generally said to be an effective speaker. Similarly, an effective writer should be able to use written words in various styles and techniques to communicate his/her message and ideas to the readers. One should have the ability to listen carefully and write and speak clearly in any situation. Therefore good reading, writing, speaking and listening skills are essential for effective communication.

Pivot tables are used to summarize, sort, reorganize, group, count, total or average data stored in a database. It allows its users to transform columns into rows and rows into columns. It allows grouping by any data field. A pivot table is a summary of your data, packaged in a chart that lets you report on and explore trends based on your information. Pivot tables are particularly useful if you have long rows or columns that hold values you need to track the sums of and easily compare to one another.

Dysgraphia can appear as difficulties with spelling and/or trouble putting thoughts on paper. Dysgraphia is a neurological disorder that generally appears when children are first learning to write. Experts are not sure what causes it, but early treatment can help prevent or reduce problems.

Symptoms

• Cramped grip, which may lead to a sore hand.
• Difficulty spacing things out on paper or within margins (poor spatial planning)
• Frequent erasing.
• Inconsistency in letter and word spacing.
• Poor spelling, including unfinished words or missing words or letters.
• Unusual wrist, body, or paper position while writing.

E-government (short for electronic government) is the use of electronic communications devices, such as computers and the Internet to provide public services to citizens and other persons in a country or region. The four types of e-government services are Government-to-Citizen (G2C), Government-to-Business (G2B), Government-to-Employee (G2E), and Government-to-Government (G2G). E-government (short for electronic government) is the use of technological communications devices, such as computers and the Internet to provide public services to citizens and other persons in a country or region.

ICT stands for Information and Communication Technology. It is used to remove complications from the ordinary tasks and also enhances communications virtually throughout the globe.

In educational field, ICT has reached greater heights by improving the system of teaching and learning. Also many schools are increasingly incorporating ICT in their primary school education system.

The ICT techniques which are used in learning/teaching plays a major role on a student’s learning capabilities. Students who are familiar with this technology to learn in school have an increased self-esteem and self-confidence.

Computers are critical for communication and are the centerpiece of information technology. The early 1990s saw the emergence of household Internet use, which eventually spurred common use of email, websites, blogs, social networking, video chat and Voice-Over-Internet Protocol. In digital communication, data is exchanged between two or more computing devices. This communication occurs over a communication medium, such as a telephone line, fiber optic cable, or wireless radio signal. The collection of digital devices and their connection media is a computer network. Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. ... A computer network available only to the residents of a building can be called a LAN.

Subsystems of a computer. The CPU, Memory, and I/O subsystems communicate with one another via the three buses.Central Processing Unit (CPU)

Controls most of the activities of the computer, performs the arithmetic and logical operations, and contains a small amount of very fast memory.

Memory: Provides storage for the instructions for the CPU and the data they manipulate.

Input/Output (I/O): Communicates with the outside world and with mass storage devices (e.g., disks, network, USB).

Communication is simply the act of transferring information from one place, person or group to another. Every communication involves (at least) one sender, a message and a recipient. This may sound simple, but communication is actually a very complex subject. The transmission of the message from sender to recipient can be affected by a huge range of things. These include our emotions, the cultural situation, the medium used to communicate, and even our location. The complexity is why good communication skills are considered so desirable by employers around the world: accurate, effective and unambiguous communication is actually extremely hard.
