Information Technology Application UG PROGRAM 21st century has come to be known as the era of Information Technology; it is the key driver of economic growth of not only a nation, but rather the whole world. The growth and progress of every sector of the country today depends on the level of Information Technology. Furthermore, technology is not important only at the work place, but also in our everyday life; whether it is working with the microwave oven which is a cooking appliance or a super computer, an appliance is based on information technology, technology helps everywhere. From hi-tech industry to an education system, Information Technology footprints can be seen everywhere. Likewise, Information Technology is one of the essential features for the overall development of a country. Meaning of Information Technology The technology, which is exclusively designed to store, process, and transmit information, is known as Information Technology. The following diagram illustrates the basic features and applications of Information Technology − Though the diagram given above is not inclusive, as it does not include every aspect and application of information technology, but it comprehensively covers the major aspects. Important Features of Information Technology Following are the major features as well as advantages of Information Technology − The development of Information Technology has made education system simpler, easier, and widespread. Now, people of remote areas can also use technology for their children’s education and also avail the benefits of adult education. Diffusion of e-governance on a large scale. Participation of public in governance and policy making. Fast economic development. Development of remote areas. Technology helps the police in nabbing the criminals. The judiciary and other administrative services can also take the help of technology to make work easier and faster.  Highly beneficial for the common people, as they can access their rights and can take legal action against the person who violates his/her rights. It increases the happiness and prosperity of not only an individual, but rather the society as a whole. Besides, there are many other advantages too that can be availed in our everyday life only with the further development of information technology. Demerits of Information Technology Information Technology is like a boon on the society. However, it comes with its own disadvantages − As discussed above, with the help of technology, police can arrest criminals and criminal activities; at the same time, technology has also opened the door for criminals as well to practice smart criminal activity. There are chances that children can misuse technology and take a wrong path. Some distorted and perverted minds use technology to demean or defame someone unethically and also illegally. These are basically not demerits but rather the misuse of technology. Information Technology Act, 2000 By understanding the growing demand and applications of Information Technology, the Government of India passed the bill of Information Technology in 2000, which came to be known as the Information Technology Act, 2000. The major features of the Act are − It facilitates e-governance and e-commerce by providing equal legal treatment to users. It made provision to accept electronic records and digital signature. It gave legal approval to electronic business transactions. The Act instructs banks to maintain electronic record and facilitate electronic fund transfer. It also sets up a Cyber Law Appellate Tribunal. In of our previous chapters, we discussed the meaning, benefits, and applications of Information Technology; in this chapter, we will discuss, the major elements, i.e., basically the core concept of Information Technology. There are different subject matters those are being studied in the topic of information technology such as computer technology, electronics, IT industries, etc. Areas Covered by Information Technology Following are the essential topics of Information technology − Electronics Electronic Technology Let us now discuss each area in brief. Electronics The purpose of using the term ‘electronics’ is to enumerate all those devices that we use in our everyday life, such as, watches, TVs, stereo systems, and many more (as shown in the image given below). Further, the electronic devices are used in the design, manufacture, sale, and repair of all faulty products. Because of the advancement in the field of technology, these days, it is possible to develop very small devices, such as small computer, small stereo system, etc. The branch of electronics that does research on the miniaturization of electronic devices is known as ‘microelectronics.’ Following are some of the significant electronic devices that play a major role in different electronic products − Semiconductor device Largely made up of silicon, semiconductor is used in almost every electronic device. Electron tube It is normally a gas-filled tube in which the current of electrons flows between electrodes. However, when the gases are removed from the tube, it acts as a vacuum tube. Analog device It is a device that can measure, record, reproduce, or broadcast continuous information. For, example, radio waves used in the AM radio. Digital device It is a device that works on the sequence of pulse-like signals. The signals are coded to characterize numbers; for example, digital watches, computers, etc. Electronic Technology Following are a few important electronic technologies − Golden-i The Golden-i device consists of various mobile wireless wearable headset computers; the device is operated by voice commands and head movements (as shown in the image given below). DNA Robot It is a device that possibly can treat deadly diseases including cancer. The technology is being researched and developed. e-Writer It is a technology that translates handwriting into plain text on the screen. There is a different handwriting recognition software that senses handwriting and transfers the written text on the screen in the same format. LCD LCD stands for ‘liquid crystal display.’ This technology has two layers of polarized glass through which the liquid crystals block as well pass light. It uses fluorescent light. E.g. LCD TVs and Monitor. LED LED stands for ‘light emitting diodes.’ The LED technology uses light emitting diodes. Encryption It is a technique that converts information or data into a code, in order to prevent unauthorized access. Other Important Areas Covered by Information Technology We will now discuss the other important areas covered by Information Technology − Telecommunication It is the technology or process of communication over a distance by means of cable, telegraph, telephone, or broadcasting. Fiber Optics It is a technology that transmits signals on the principle of Total Internal Reflection (TIR) of light. The technology employs transmission of data in pulses of light form. Integrated Service Digital Network (ISDN) ISDN is a set of communication standards that simultaneously transmits voice, video, data, and other network services in digital form over the traditional circuits of the public switched telephone network. Computer A computer is a programmable electronic device that manipulates and manages different sorts of data and information. A computer can store, process, and retrieve the save data. Blue-Gene Computer It is one of the fastest supercomputers developed by the IBM Crop. Cloud Computing Cloud computing is a technique of using a network of remote servers hosted on the Internet with the purpose to store, manage, and process data. The technique keeps data safe and makes your data available anytime and anywhere; in other words, you don’t need to carry your computer device to carry data you access your data on any computer with internet facility. The crime that involves and uses computer devices and Internet, is known as cybercrime. Cybercrime can be committed against an individual or a group; it can also be committed against government and private organizations. It may be intended to harm someone’s reputation, physical harm, or even mental harm. Cybercrime can cause direct harm or indirect harm to whoever the victim is. However, the largest threat of cybercrime is on the financial security of an individual as well as the government. Cybercrime causes loss of billions of USD every year. Types of Cybercrime Let us now discuss the major types of cybercrime − Hacking It is an illegal practice by which a hacker breaches the computer’s security system of someone for personal interest. Unwarranted mass-surveillance Mass surveillance means surveillance of a substantial fraction of a group of people by the authority especially for the security purpose, but if someone does it for personal interest, it is considered as cybercrime. Child pornography It is one of the most heinous crimes that is brazenly practiced across the world. Children are sexually abused and videos are being made and uploaded on the Internet. Child grooming It is the practice of establishing an emotional connection with a child especially for the purpose of child-trafficking and child prostitution. Copyright infringement If someone infringes someone’s protected copyright without permission and publishes that with his own name, is known as copyright infringement. Money laundering Illegal possession of money by an individual or an organization is known as money laundering. It typically involves transfers of money through foreign banks and/or legitimate business. In other words, it is the practice of transforming illegitimately earned money into the legitimate financial system. Cyber-extortion When a hacker hacks someone’s email server, or computer system and demands money to reinstate the system, it is known as cyber-extortion. Cyber-terrorism Normally, when someone hacks government’s security system or intimidates government or such a big organization to advance his political or social objectives by invading the security system through computer networks, it is known as cyber- terrorism. Cyber Security Cyber security is a potential activity by which information and other communication systems are protected from and/or defended against the unauthorized use or modification or exploitation or even theft. Likewise, cyber security is a well-designed technique to protect computers, networks, different programs, personal data, etc., from unauthorized access. All sorts of data whether it is government, corporate, or personal need high security; however, some of the data, which belongs to the government defense system, banks, defense research and development organization, etc. are highly confidential and even small amount of negligence to these data may cause great damage to the whole nation. Therefore, such data need security at a very high level. How to Secure Data? Let us now discuss how to secure data. In order to make your security system strong, you need to pay attention to the following − Security Architecture Network Diagram Security Assessment Procedure Security Policies Risk Management Policy Backup and Restore Procedures Disaster Recovery Plan Risk Assessment Procedures Once you have a complete blueprint of the points mentioned above, you can put better security system to your data and can also retrieve your data if something goes wrong. In today’s world, e-infrastructure is the key element for the development of a society. E-infrastructure facilitates competent equipment and favorable resources and opportunities that are essentially needed to for the safety, security, and development of a society. Further, e-infrastructure helps to integrate various technologies including different computer systems, internet broadband channels, computing power, data storage, data sharing, and many more. To meet the growing challenges of globalization and also cope-up with the sustainable growth of information and communication technology, it is essentially required to integrate these systems by developing better e-infrastructure. Initiatives By understanding the growing demand and challenges, the Department of Information Technology formulated a ‘National Policy on Universal Electronic Accessibility’. The policy was approved by the union cabinet in 2013. The major strategies adopted in the implementation of the policy have been taken from the Press Information Bureau Government of India Cabinet October 3, 2013 − Creating awareness on universal electronics accessibility and universal design. Capacity building and infrastructure development. Setting up of model electronics and ICTs centres for providing training and demonstration to special educators and physically as well as mentally challenged persons. Conducting research and development, use of innovation, ideas, technology etc. whether indigenous or outsourced from abroad. Developing programme and schemes with greater emphasis for differently abled women/children. Developing procurement guidelines for electronics and ICTs for accessibility and assistive needs. ITIR For the exclusive growth of E-infrastructure in India, the Government of India has formulated the policy on ‘Information Technology Investment Regions (ITIRs) in 2008. As per the policy, ITIRs will be self-contained integrated township with the purpose to accelerated growth of Information Technology, Information Technology Enabled Service, and Electronic Hardware Manufacturing units. Further, the policy has recommended to assign minimum area of 40 sq. km for ITIR. However, out of the total demarcated area, 40% should be reserved for the processing zone and the remaining area for the non-processing zone. The processing zone will include − Information Technology/Information Technology Enabled Services Electronic Hardware Manufacturing Units Logistics and other services and required infrastructure. On the other hand, the non-processing area will include − Residential area Commercial area Other social and institutional infrastructure National Knowledge Network In 2009, in order to create an infrastructure that can fulfil the future requirements, the concept of ‘National Knowledge Network’ (NKN) is conceptualized. The concept of NKN is designed to Encourage, Enable, Enrich, and Empower the user community to test and implement the innovative ideas without any restrictions. Further, the NKN will provide better −  Network design Security requirements Service requirements Operational requirements Dot Bharat The concept of developing the domain and website in ‘Devnagri’ (native script) was launched in August 2014.
