We live in the fascinating and challenging world of science. It is a world that more and more over the ages, and especially in the 20th century has come to affect so much of our lives. It is involved with the way we travel, the homes we live in and the clothes we wear, how we become ill and how medicine can make us better, and has given us fantastic means of communicating and exploring.
The list of the inventations is rather long. We are on-lookers of great scientific achievements such as television and a computer. We can't imagine our life withought a notebook or a radio. I'd like to speak in details about computers.
What is a computer?
A computer is an electronic device that stores information and allows changes in it through the use of instructions. A modern computer is capable of doing various tasks, like word processing and accounting. Personal computers are widely used but working on them requires some techniques.
The biggest challenge of my compure work was adapting to software that has been "upgraded" e.g. MS Word 10, in which perfectly efficient software is changed with different menus, commands but no real innovation.
Technology changed since I was a child - road trips just aren’t the same without getting lost or stopping to ask for directions; еhe world is at our fingertips... and we can bypass the mean librarian; тo more running to get into the picture before the timer goes off... behold, the “selfie stick”.
Since the beginning of the new millennium, the world has witnessed the emergence of social media, smartphones, self-driving cars, and autonomous flying vehicles. One of the biggest technology trends in recent years has been smart home technology, which can now be found in everyday consumer devices like door locks, light bulbs, and kitchen appliances. The key piece of technology that has helped make all this possible is the digital assistant.
I published pictures of family, life experiences and recent activities and posted them in Internet
