1. Massive Open Online Courses (MOOC) are changing the world of education by providing free online courses.

2. MOOC is a web-based free distance learning program that ensures the participation of students from geographically remote areas in the field of education.

3. It offers free online courses for higher education, executive education and employee development.

1. The full form of OTP is One one-time password.

2. OTP is used as one of the additional security features for secure online transactions.

3. The OTP feature prevents certain types of identity theft by ensuring that a captured username/password pair cannot be used a second time.

4. The user's login name usually remains the same, and the one-time password changes with each login.

5. One-Time Password (aka One-Time Passcode) is a form of strong authentication, providing better security to eBanking, corporate networks, and other sensitive data systems.

Integrated circuits (ICs) were first introduced during the third generation of computers. The third generation of computers, which emerged in the 1960s, saw the development and widespread use of integrated circuits. These tiny electronic circuits contained multiple transistors, resistors, and capacitors on a single semiconductor chip. The use of integrated circuits significantly reduced the size of computers, increased their processing speed, and improved their reliability, marking a significant advancement in computer technology.

A plotter is an output device that prints vector graphics on hard copy. Unlike printers, which are designed for raster graphics and text, plotters are specialized devices used to produce high-quality drawings, diagrams, and other vector-based illustrations. Plotters use pens or other drawing tools to create precise lines and shapes on paper, making them particularly useful for applications that require detailed and accurate graphical output, such as architectural and engineering designs.

An output device that is used for TV-like displays and shows the output on the screen is indeed called a monitor. It is also commonly referred to as a visual display unit (VDU). Monitors and VDUs are used to display visual information from computers and other electronic devices, allowing users to view text, images, videos, and other graphical content. They come in various types, including CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), LED (Light Emitting Diode), and OLED (Organic Light Emitting Diode) monitors.

a color monitor is a type of display that can adjust and display output by manipulating the Red, Green, and Blue (RGB) radiation. In a color monitor, pixels are made up of red, green, and blue sub-pixels, and by varying the intensity of these colors, a wide range of colors can be displayed on the screen. Adjusting the intensity of RGB radiation allows the monitor to display different colors and shades, providing a full spectrum of colors to the viewer. This technology is commonly used in computer monitors, television screens, and other displays to produce vibrant and accurate color representations.

Actually, the correct acronym for Reusable Optical Storage is not ROM. The correct acronym is ROS, which stands for Reusable Optical Storage. ROS refers to a technology that allows optical storage media, such as DVDs and CDs, to be rewritten or reused multiple times for data storage purposes.

 A Virtual Private Network (VPN) is a technology that allows users to create a secure and encrypted connection to another network over the internet. VPNs are commonly used to ensure privacy and security when browsing the internet, especially when using public Wi-Fi networks. VPNs create a private tunnel for data transmission, protecting users' online activities from surveillance, censorship, and potential cyber threats.
