Copy into Word, then research the code or method of communication used.

Communication Type	What was it?	When was it used?	What did it replace?	What replaced it?
The Pony Express 24 hours...rain or shine! MAP	The Pony Express was a mail company that used horseback to carry mail across Missouri and California.	April 3, 1860 – October 24, 1861	Replaced mail by stagecoach.	The telegraph made a faster and cheaper method to send information.
Morse Code	Morse Code is a series of alphabet or code being transmitted by short or long ranges signals lights or clicks.	1844-present (barely used)	Replaced the telegraph.	Replaced by telephone, fax, and the internet or ASCII.
Semaphore	Semaphore is almost like morse code using two flag poles in a certain position to send a message.	1792-present (barely used)	Replaced the telegraph.	Replaced by Electrical Telegraphs.
ASCII (American Standard Code for Information Interchange)	ASCII is sets of bit code that replaces alphabetic, numeric, or special characters. Mainly used for computers	1960-present	ASCII replaced morse code.	Replaced by UTF-8 encoding.

This is the Challenge! Copy the code representations for the word Pat.

Career Assignment 2!

“95% of new businesses fail after the first two years”

Why the heck would I want to be an entrepreneur ...

Career	Job	Entrepreneur
An occupation that takes ups most of a person's lifetime.	Work that a person gets regularly paid and employed. Sometimes occasional.	A person who sets up and manage their own business. Also to take financial risks.

      QUESTIONS:

1.    What does an entrepreneur have that other people don’t have?

2.    Do you know anybody with that ambition? Who? What do they do?

3.    The website admires 5 entrepreneurs. Which entrepreneur do you find the most interesting? Why?

4.    How much does this course cost?

5.    Would you be interested in this course if you received an entrepreneurship scholarship to take it?

ANSWERS:

1. An entrepreneur has that other people don't have is hard workmanship. They are willing to push their own boundaries for their business. Learning from every experience, they plan ahead to keep their business afloat. They work day and night to improve and become successful in their career. The hardships that they take really make them different than other people.

2. I find my parents (and also many other parents) with a strong ambition. They work tirelessly for me, especially for my future. They want to make sure I'll be successful in life much more than them. Most parents always try to do what's best for their kids and that's really when their ambition kicks in. It's determination and a goal to make their kids happy with themselves and their future.

3. I find Warren Buffet interesting. His holdings company is respected worldwide, for a good reason. He seems like a humble and honest man, living in his home he bought 50 years ago. His net worth exceeds US $47 billion. He doesn't spend it on materialistic things. He rather pledges 85% of his fortune to the Bill and Melinda Gates Foundation.

4. This course is located in North York, and classes will run for 3 weeks between July and August. From May 31, the course will cost $300, and after that, until June 15 the course will cost $500 or $300 if you hand in a 500 word essay about the most important business skill.

5. If I would receive an entrepreneur scholarship, I would happily take the course. As education improves, teenagers will be able to take advantage of courses like this. Unlike before, an "entrepreneurship bootcamp" was never heard of. Teenagers would rely on friends/family and themselves to become an entrepreneur. It was more difficult and many skills were needed. With courses like this, being prepared for the future will be easier and will set up many career paths for the future.

People of the Computer Age! 20th - 21st Century

1st, 2nd, 3rd Generation

 Robert Noyce 

Robert Noyce was the co-founder of Fairchild Semiconductor (1957) and Intel (1968). Along with Jack Kilby, he created the integrated circuit. He was also called the "Mayor of Silicon Valley," long before California had the name Silicon Valley. Robert Noyce was born on December 13, 1927. Noyce grew up in Grinnell, Iowa. He earned a bachelor of Arts in physics and mathematics from Grinnell College, and a Ph.D. in Physics from Massachusetts Institute of Technology.

4th Generation

Michael Dell

Michael Dell is the founder and CEO of Dell Inc. (1984). Michael Dell was born on February 23, 1965, in Houston, Texas, he had a love and interest in computers. In college Dell, decided to sell PCs directly to the customers. Unlikely at the time, he wanted to eliminate the middleman and markups, so he saved up $1,000 and started building computers for people he knew in college. Sooner or later he had been receiving many orders, which proved that his business was booming. He later dropped out to focus on the business and gain a huge success not only for directly selling the PCs but also with excellent customer service.

WWW Generation

Sergey Brin

Sergey Brin is the co-founder of Google (1998) and president of Google's parent company Alphabet Inc. (2015). Sergey Brin was born on August 21, 1973, in Moscow, Russia. In his early life, Brin and his family emigrated to the U.s to escape Jewish prosecution in 1979. Brin enrolled in the University of Maryland and earned a degree in mathematics and computer science, he then entered Stanford University where he met Larry Page (co-founder of Google and CEO of Alaphabet Inc.). As a hobby and a research project, Sergey Brin, and Larry Page, created a search engine that listed web pages based on their popularity, which would be most useful. Then they decided to raise $1 million from family, friends, and other investors to launch the company, Google (based on the word "googol", 1 followed by 100 zeros, to be based on the many web pages of the internet).

Computer Generations Table!

Generation	Examples of Computer (Name)	Electronic Components	Years	Used for?	Size	Interesting fact about each
1	The Colossus	Vacuum Tubes	1940-1956	Vacuum tubes are used for radios, television, radar equipment, and telephones.	Took up a Room	Today some vacuum tubes are used for speakers, which audiophiles say that the audio quality is better than normal transistors.
2	The Manchester Transistor Computer	Transistors	1956-1963	Replaced vacuum tubes, allowing computers to be faster, smaller, power efficient and cheaper.	Took up a room but still less than a vacuum tube computer.	Transistors still used punched cards for input and printouts for outputs,
3	IBM 1311	Chips (Integrated Circuits)	1964-1971	Just like the transistors, the integrated circuits replaced them being much faster and efficient. Now they can store many data and can make more calculations.	Took up half a room.	Most integrated circuits have gold in them. Now as they are obsolete, some people extract gold out of the chip and sell them for money.
4	Sunway TaihuLight	Microprocessors (Computers on a chip)	1971-Present	Replacing the old integrated circuits, most computers only have one microprocessor which made them a lot more compact, faster, cheaper and efficient.	General computers took a small portion of a room. A supercomputer would take a whole room.	Microprocessors were made by many companies before. Now there are only two companies that take up most of the microprocessor market, Intel and AMD.
5.	Google Data Servers	Networking Parallel Computing Fibre Optics	Present - Future	Unlike a physical hardware state, computers are accessing the cloud for information, apps, communication, and many more.	Servers would take up a room, but computers accessing the cloud would take no space at all.	The cloud is mainly servers from around the world. Most servers still use microprocessors. But since this is just the beginning new technology are starting to be developed by engineers/scientists all around the globe.

History of Computers: Day 1!

1. There is no real answer to when the computer was first created. The word "computer" was first used in 1613, to describe a person who performed calculations. The first programmable computer was created by German Konrad Zuse, called Z1. It is considered to be the first electro-mechanical binary computer. The first commercial computer was made in 1942, by Konrad. It was called the Z4. There are different classifications of computers so they will be linked here.

2. The most important History pioneer is Tim Berners-Lee. Tim invented the World Wide Web (WWW), which we all use today. Without the World Wide Web, we would've not been able to connect to the cloud or collaborate and communicate with anyone around the web. 

3. The first video game was called Spacewar! The game was programmed by Steve Russel and published the game in February 1962. The game had two spaceships that were being pulled by a star. The objective of the game was to avoid the star and shoot missiles at the other ship. The game ran on the DEC PDP-1 computer.

4. The World Wide Web was invented by Tim Berners-Lee.

5. The computer mouse was created by Douglas Engelbart. He released his demo on December 9, 1968. You can find more on the video here.

6. The first programming language was called Plankalkül. It was developed by Konrad Zuse, used for the Z3 between 1943 and 1945.

7. The "Father" of computing was Charles Babbage. He created the Analytical Engine in 1837 and contained an Arithmetic Logic Unit (performs mathematical operations on binary numbers), basic flow control, punch cards, and integrated memory. It essentially was the first general-purpose computer.

The "Father" of the computer was Konrad Zuse. In 1936 to 1938 Konrad created the Z1 in his parent's living room. The Z1 had more than 30,000 metal parts and was considered to be the first electro-mechanical binary programmable computer.

The "Father" of the personal computer was Henry Edward Roberts. He came up with the idea of a "personal computer". When he released the Altair 8800 on December 19, 1974, he was considered to be the father of the modern personal computer. The "personal computer" was published n the front cover of Popular Electronics in 1975 became an overnight success. The computer was sold as a kit for $439 or assembled for $621 and had different add-ons. By 1975, over 5,000 Altair 8800 was sold.

8. Alan Turing was so important to Computing history because, during the second world war, Turing worked for the Government Code and Cypher School. He was responsible for 
 deciphering many German ciphers. He cracked many intercepted coded messages that enabled the Allies to defeat the Nazis. He created a machine (the Bombe) that help break the code of the Enigma machine that the Germans created.
