Computer security, also known as cybersecurity or IT security, is the protection of computer systems from theft or damage to the hardware, software or the information on them, aswellasfrom disruption or misdirection of the services they provide.
Our daily life, economic vitality, and national security depend on a stable, safe, and resilient cyberspace.
Why do need to learn about Computer Security? Isn’t this just IT problem? Information is stored on computer hardware, manipulated by software, transmitted by communication, used by people, etc. each of these areas must be adequately protected!
“In the last 20 years, technology has permeated every facet of the business environment. The business place is no longer static – it moves whenever employees travel from office to office, from office to home, from city to city. Since business have become more fluid, …, information security is no longer the sole responsibility of a small dedicated group of professionals, …, it is now the responsibility of every employee, especially managers.”
Information security should balance protection & access - a completely secure information system would not allow anyone access, or would be very ‘user-unfriendly’!

1. Сұрақ: Explain Evolution of ICT
ICT stands for information communication technology. This can be described as everything from the very first alphabets and hand signals through to tweeting and texting.
The evolution of the first ICT to our current form of ICT goes through 4 stages, Premechanical, Mechanical, Electromechanical and Electronic.
Premechanical. This is the earliest age of information technology. The communication methods during this time included mostly oral communication, as well as some of the very first alphabets. This is where we see hieroglyphics and the Phoenician alphabet. The premechanical age of technology is the earliest known form of ICT. It can be defined as the time between 3000B.C. and 1450A.D. (was created abacus).

Mechanical. Many new technologies came about in this era as interest in ICT grew. During this period, Charles Babbage created the first sort of calculator and a mechanical computer was manufactured by Blaise Pascal. The mechanical age can be defined as the time between 1450 and 1840. Blaise Pascal invented the Pascaline which was a very popular mechanical computer. Charles Babbage developed the difference engine which tabulated polynomial equations using the method of finite differences.
Electromechanical. This was the beginning of telecommunications. Famous inventions such as the telephone, morse code and telegraph came about in this time. The very first automatic digital computer was created during this period also. The electromechanical age can be defined as the time between 1840 and 1940. These are the beginnings of telecommunication. The telegraph was created in the early 1800s. Morse code was created by Samuel Morse in 1835. The telephone (one of the most popular forms of communication ever) was created by Alexander Graham Bell in 1876. The first radio developed by Guglielmo Marconi in 1894
Electronic. This is the age we live in today. In our current society, we are using all kinds of technology to communicate such as texting, tweeting, social media and smartphones. The electronic age is what we currently live in. It can be defined as the time between 1940 and right now. The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems.
Future of Technology.
As our needs grow and our ideas expand, there is an endless expansion of technology available. New inventions could see us going inside virtual worlds, or maybe even inhabiting outer space...
Only time will tell what the future of technology will hold.
