The document provides a brief history of the development of computers and the internet. It discusses how the first programmable computer was created in 1943, the first connection between two computers occurred in 1965, and how initially the internet only allowed communication between two devices but now connects a vast network of computers and devices globally. It also outlines how computers and the internet have transformed everyday life through technologies like email, search engines, and video calling, and how computer viruses originated as practical jokes but now pose serious cybersecurity threats.
2. Useful Machines ►Computers have been around for a very long time, and they help shape today’s everyday life. ►They help to shape and make today’s everyday life easier.
3. Computers Are Born... ►In 1943, the first fully programmable computer was born. ►This is a replica of the Zuse Z3 computer.
4. Computer Networking ►In 1965, a MIT student connects a computer in Massachusetts to a computer in California through Dial-up phone lines. ►This was the first connection between two computers ever established.
5. The Internet ►At first, the internet was only from one computer to another. ►Today, the Internet is a massive computer network, that shares pages, and information over a wide stream of computers, and other devices.
6. Changing Everyday Life ►From the start, computers began to change everyday life, and make things easier than ever before… ►Things like Email, Wikipedia, Google search, and Skype have changed the way we communicate entirely.
7. The Virus ►The computer virus was originated in the early 1980s, as a practical joke that caused an elk to appear on the computer screens, and spread by seemingly innocent floppy disks. ►Today, computer viruses are far more serious, and can remain hidden in your computer, and steal important data, and transmit it over the internet, to un-trusted sources.
8. It’s still safe, though… ►Today, we have come up with many different ways to prevent a virus attack. ►An Antivirus program is a program that runs silently, and looks for suspicious activity in your computer, and stops anything that could be harmful.
