Cloud Computing  Using different computing resources, such as hardware and software, through a computer network system is called cloud computing. The method used to access some global facilities by connecting to the Internet is called cloud computing. Through this, the remote user gets the data, software and results of the processing through the computer. Cloud computing services started in 2005. Amazon.com's Elastic Compute Cloud (EC2) was the first to offer this service. Although the concept of cloud computing is not new. The concept of central computing was introduced in the sixties. According to that idea, big companies plan to install a mega computer in every city. City dwellers will receive computer services through lines like electric or dish lines. The project did not materialize due to network speed limitations. The concept of grid computing in the 1990s is also basically a concept of cloud computing. At present, famous companies like IBM, Microsoft, Google etc. are provid...

Network Devices Modem :  The modem consists of Modulator Mo and Demodulator Dem Voice is an important and widely used electronic device used in computer communication systems. The computer is connected to the telephone line through a modem. As a result, it is possible to send data from a computer to any part of the world through a modem and phone line. In this case, the receiving computer must also be connected to the phone line through a modem.  The modem's function is to convert a digital signal to an analogue or modulate and Digitalize or demodulate analogue signals. Analogue signals can flow through normal telephone lines, but computers use digital signals. Therefore, the digital signal provided by the computer has to be converted into an analogue signal to be sent over the telephone line. And the work of converting this digital signal into an analogue signal is done by the modem connected to the sending computer. The modem sends the converted signal to the receiver over t...

Mobile Communication A mobile phone is a small electronic device for receiving and transmitting sound or data that has input and output units A display unit is also used to make a cellular phone or mobile phone.

Concept of data communication system: Data transfer between a central computer and remote terminals was first introduced in the 1960s. These terminals lacked storage and processing capabilities. Such a method is known as teleprocessing. The terminal of this method is called the silent or dumb terminal. Later, processing and data storage and data storage capabilities were created in these terminals, known as self-contained systems. Data is a precious resource in today's era. Information or data plays an important role in the improvement of an organization, making realistic decisions for the organization, connecting the internal environment of the organization with the rapidly changing world outside, etc. The special method by which data is exchanged from one computer to another or more computers is called the data communication method. The advantage of this method is that data can be transmitted quickly and accurately. The main five components or parts of data communication are— 1. ...

After a few days of data processing by one computer in an organization, the need and tendency to use multiple computers is seen. The demand for work also increased. Even today many households use more than one computer. When operated by a computer alone, all hardware and software are used only for that computer. But when multiple users are connected to a computer network, different hardware and software can be shared. Communication System --  The impact of information technology on the evolution of civilization is immense. Numerous products and services are created in society for better living systems and the development of these systems. People can easily adopt it through the proper use of management and technology. Concept of Communication System: At one time, people used to send information from one place to another by tying the feet of pigeons. Horse calls were also prevalent among civilized nations. The system of runners for sending news from one place to another was prevalen...

Also, personal privacy is being disturbed in many cases through the use of information technology. Online banking systems are being disrupted by internet hackers. Automation is increasing in many fields due to the benefit of information technology, thus increasing unemployment. In addition to this, th...

Genetic Engineering The process by which the acquired knowledge of heredity is used for human welfare is basically called genetic engineering. Genetic engineering is a process in which parts of DNA or RNA that protect the offspring are removed or inserted into cells. Sometimes it is also called genetic modification. It is a branch of biochemistry in which life is defined at the molecular level. The journey of genetic engineering began with the discovery of recombinant DNA technology by Paul Berg in 1972. The term "genetic engineering" was first used in 1951 by Jack Williamson in his science fiction novel Dragon's Island. A year before that, Alfred Hershey and Martha Chase confirmed that DNA is the carrier of heredity. Some other branches of biotechnology like microbiology, biochemistry, biostatistics, tissue culture like genetic engineering is also a branch. Genetic engineering involves removing DNA carrying a specific gene from an organism and transferring it to a differ...

Space Exploration Knowledge of space in the 20th century is not possible without the use of information and communication technology. By capturing, processing and storing data, it is possible to quickly learn about starlight falling on the surface, space, other planets and Earth. In September 1962, US President Kennedy made an appeal to students and faculty at Rice University for American research into space. Man wanted to go to the moon not because it was easy, but because it was challenging. Man traveled to the moon by proving the power and capability of man. Information technology was still being used when Galileo was looking at the stars, moon and planets through a telescope. When space travel was first ventured into, not much was possible without the help of IT. Space flights move at such high speeds that it is impossible for humans to calculate their positions. Let's say the rocket is traveling at 30,000 km/hr in space. The speed, trajectory, fuel, temperature, direction etc....

Cryosurgery Another name for cryosurgery is cryotherapy. The word cryo means ice cold. Cryosurgery is a procedure in which abnormal body tissues are removed at extremely low temperatures. This method has been used in various skin treatments for about a hundred years. Currently, this method is widely used in the treatment of various skin diseases such as acne, mechata, mole mecha and skin cancer. Currently, cryosurgery or cryotherapy is being used to treat not only skin but also liver, piles, mouth cancer, prostate or certain types of bone cancer, cervical cancer. Cryosurgery is very popular in the treatment of prostate cancer in elderly patients. If there is a tumor somewhere inside the body, a thin needle-like instrument, known as a cryoprobe, is inserted into the tumor. The cryowasher contains a camera to collect ultrasound images. The cryoprobe is connected to a computer. Specialists can manage the operation by viewing the location through special software.  This technology is m...

Artificial Intelligence Intelligence or the ability to think that animals have which no physical object has. However, the long-term efforts of scientists have made it possible to give at least some thinking power to machines. This is basically artificial intelligence. The word intelligence is a collective form of several special qualities. Such as thinking about a particular subject, making decisions, solving problems, learning from experience, acquiring knowledge about any subject, applying acquired knowledge, responding quickly and successfully to new situations, understanding language — All this is part of intelligence. The word artificial can be placed before this intelligence or intelligence only when it is possible to simulate these qualities in a system.

Virtual Reality 1961 Morton L. Heilig's first virtual reality debut with a device called the Sensorama stimulator. However, computers had nothing to do with this technology. Virtual reality is not real, but science-based imagination that creates the illusion of reality. At the center of this world is a highly dynamic specialized microprocessor known as the Reality Engine. It requires a computer with high processing quality to use it. It is based on computer technology and simulation theory. One can only read or watch an event on TV or in a book, one cannot actively engage with that event. But in reality it is hypothetically possible. Much like video games, where it is possible to exercise one's imagination within the main program. It is also possible to travel to the depths of the Pacific Ocean, if you wish to see giant dinosaurs. Everything we see around us is three-dimensional and colorful. The help of two three-dimensional glasses is taken to reveal the three-dimensional rea...
