5. Touch screen

A touch screen is a display screen that can detect the presence and location of a touch within the display area. Touch screens can be used to control graphical user interfaces, play games, and interact with other electronic devices.

• Capacitive touchscreens
  

  Capacitive touchscreens work by detecting changes in the electrical field around the screen. When a user touches the screen, their finger changes the capacitance of the screen, which is detected by the touchscreen controller. Capacitive touchscreens are very sensitive and can be used with a variety of styluses and other pointing devices.

• Resistive touchscreens
  

  Resistive touchscreens work by detecting changes in the electrical resistance between two layers of conductive material. When a user touches the screen, the two layers of material come into contact, which changes the resistance. Resistive touchscreens are less sensitive than capacitive touchscreens, but they are also more durable and can be used with a wider variety of objects.

• Infrared touchscreens
  

  Infrared touchscreens work by detecting changes in the amount of infrared light that is reflected back to the screen. When a user touches the screen, their finger blocks some of the infrared light, which is detected by the touchscreen controller. Infrared touchscreens are very durable and can be used in a variety of environments, including outdoor environments.

• Surface acoustic wave touchscreens
  

  Surface acoustic wave touchscreens work by detecting changes in the surface acoustic waves that are generated on the screen. When a user touches the screen, their finger damps the surface acoustic waves, which is detected by the touchscreen controller. Surface acoustic wave touchscreens are very sensitive and can be used with a variety of styluses and other pointing devices.

Touch screens have become increasingly popular in recent years, and they are now used in a wide variety of electronic devices, including smartphones, tablets, and laptops. Touch screens are also used in a variety of industrial and commercial applications, such as point-of-sale systems and medical devices.

6. Object-oriented programming

Object-oriented programming (OOP) is a programming paradigm that uses "objects" to design applications and computer programs. "Objects" are data structures consisting of data fields and methods together with their interactions. This makes it easier to create complex programs that are easier to maintain and reuse. Alan Kay is one of the pioneers of OOP, and his work on the Dynabook at Xerox PARC in the early 1970s helped to lay the foundation for the development of modern OOP languages.

OOP has several advantages over other programming paradigms, including:

• Modularity: OOP makes it easier to create modular programs that can be reused in different contexts. This can save time and effort, and it can also make it easier to maintain and update programs.
• Encapsulation: OOP allows you to encapsulate data and methods within objects, which can help to improve security and maintainability. This can also make it easier to create programs that are extensible and reusable.
• Inheritance: OOP allows you to create new classes that inherit the properties and methods of existing classes. This can make it easier to create complex programs that are based on existing code.

OOP is a powerful programming paradigm that is used in a wide variety of applications, including operating systems, web browsers, and video games. Alan Kay's work on OOP was a major breakthrough in the development of modern computing, and his ideas continue to shape the development of new programming languages and technologies today.
