Keyboard
In our TLE class we've studied some things about the keyboard. We have studied the parts of the keyboard. We also study the proper keyboarding so that there are no mistakes will occur in typing. At first I didn't memorize yet the parts of the keyboard, but now I memorize already the parts. At first it's difficult in memorizing because there are so many keys to remember. But if you try to remember and memorize it you could easily know the parts of the keyboard.
Softwares
In this lesson we've learned about the different kinds of softwares. There are two main types of computer software that all computers require to function - system software and application software. System software is the initial software that makes up the underlying functioning of a computer, and provides a platform for applications software to run on. Application software allows computer users to perform tasks and run programs, and could be considered secondary software that builds on primary system software.
History of Computers
In this lesson we learned many things about the different kinds of computers, their inventors and all about the 5 generations.
The Generations:
First Generation (1940-1956) Vacuum Tubes
The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer.
Second Generation (1956-1963) Transistors
In the second generation the computers use a transistor. The transistor was invented in 1947. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than the first generation.
Third Generation (1964-1971) Integrated Circuits
Another name for a chip, an integrated circuit (IC) is a small electronic device made out of a semiconductor Texas Instruments. The first integrated circuit was developed in the 1950s by Jack Kilby of
Integrated circuits are used for a variety of devices, including microprocessors, audio and video equipment, and automobiles.
Fourth Generation (1971-Present) Microprocessors
A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC, or microchip). It is a multipurpose, programmable, clock-driven, register-based electronic device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. It is an example of sequential digital logic, as it has internal memory, i.e. its registers. Nearly all microprocessors, currently and historically, accept, produce, and internally operate on binary data (binary code and binary numbers), making them binary digital computer processors. (This is one point that differentiates microprocessors as a class, architecturally, from early non-integrated circuit computers such as vacuum tube computers, many of which used decimal digital logic in their vacuum tube circuits.)
Fifth Generation (Present and Beyond) Artificial Intelligence
Fifth generation use now the "Artificail Intelligence".Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as "the study and design of intelligent agents"where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.John McCarthy, who coined the term in 1956,defines it as "the science and engineering of making intelligent machines."

My ReFlEcTiOn
I just want to say that I have learned many things in the T.L.E class. I learned how a good Entrepreneur achieves his/her different goals. I learned about the different PEC's characteristics with the 3 clusters. And I also learned that being an entrepreneur is hard to many people but it can be also easy to them if they work it hard.
