ESSAY

 

1. What are digitization, the digital revolution, and digital convergence, and how do they affect your life?

 

ANS:

Digitization is the process of converting text, numbers, sound, photos, and video into data that can be processed by a computer. The advantage of digital images and sounds is that they can be easily stored, copied, and shared. Digital images have changed the photographic industry. Digital cameras have replaced film cameras. Digital imaging used in medical tests has had profound effects in the healthcare industry. Digital video is responsible for special effects in movies, new trends in 3D animation, portable video, and consumer interest in home video. Digital sound transformed the way music is marketed, sold, purchased, and played. Human speech can also be digitized. For example, when you call a business for help or information, digitized voice telephone systems understand and respond to your spoken words. GPS devices tell you the directions as you drive.

 

The digital revolution is the process of social, political, and economic change brought about by digital technology, such as computers and the Internet. The digital revolution affects people’s lives in that it influences the tools they use to teach, play, work, and govern by digitizing or enhancing devices.

 

Digital convergence refers to blending unrelated technologies into a single product. This affects anyone who has a device such as a smartphone, which includes phone capabilities in addition to a keypad, email, Web browser, camera, music player, GPS, etc.

2. List advantages of each of the following computer types: notebook, tablet, and netbook.

 

ANS:

A notebook is a type of portable personal computer, and is smaller than a desktop, although more expensive. Notebooks, when closed, protect the components such as pointing device, screen, and keyboard. Notebooks are comparable in computing power to desktops.

 

A tablet includes a touch-sensitive screen, on which you can write or draw to provide handwritten input. Most also accept voice input. These are best for people who do their work while on the go, such as real estate agents or healthcare workers.

 

A netbook is a more portable notebook. They are scaled-down notebooks, and weigh much less.
