HISTORY OF COMPUTER
In our modern generation many gadgets are improving like computer.
But did we know how it start?
Base on my opinion, it started in very low but see now it's very progressive.
And I believe it will improve more...
Brief History of Computers
A Look Back at Computing
Computers have become one of the most important parts of modern society. Nearly everything that is modern required or uses computer related technology in some way. But how did computers as we know them come to exist? Did someone sitting in his lab just one day say, "Aha! I've got it! The computer!"? Well, no, that is not how this happened. Rather, many years of brilliant ideas and research from many different individuals contributed to modern computing. The field is constantly evolving at a pace unlike anything before it as techniques are polished and new breakthroughs are made.
First Generation (1950 - 1957)
The first computer to implement Von Neumann's idea was the EDVAC in 1951, developed in a project led by Von Neumann himself. At the same time a computer using stored programs was developed in England, called the EDSAC. [25] The EDVAC was commercialized and called the UNIVAC 1. It was sold to the U.S. Bureau of the Census in March, 1951. This was actually the first computer ever built for sale. [26] The UNIVAC 1 made a famous appearance on CBS in November, 1952 during the presidential election.
Second Generation (1957 - 1965)
The second generation of computing took place between 1957 and 1965. Computers were now implementing transistors, which had been invented in 1947 by a group of reseachers at Bell Laboratories, instead of vacuum tubes. [30] Because of the transistor and advances in electrical engineering, computers were now cheaper, faster, more reliable, and cheaper than ever before. More universities, businesses, and government agencies could actually afford computers now.Third Generation (1965 - 1975)
he third generation of computing spanned from 1965 to 1975. During this time integrated circuits with transistors, resistors, and capacitors were etched onto a piece of silicon. This reduced the price and size of computers, adding to a general trend in the computer industry of miniaturization. In 1960 the Digital Equipment Corporation introduced the Programmed Data Processor- 1 (PDP-1), which can be called the first minicomputer due to its relatively small size. [34] It is classified as a third generation computer because of the way it was built, even though it was made before 1965. The PDP-1 was also the computer that ran the very first video game, called Spacewar (written in 1962).Fourth Generation (1975 - 1985)
The fourth generation of computing spanned from 1975 to 1985. Computer technology had advanced so rapidly that computers could fit in something the size of a typewriter. These were called microcomputers, the first one being the Altair 8800. The Altair 8800 debuted in 1975 as a mail-order hobby kit. Many people acknowledge the Altair 8800 as the computer that sparked the modern computer revolution, especially since Bill Gates and Paul Allen founded Microsoft with a programming language called Altair BASIC-- made specifically for the 8800. [36] Now that computers could fit on desks they became much more common
Fifth Generation (1985 - Present)
The changes that have occurred since 1985 are plentiful. Computers have gotten tinier, more reliable, and many times faster. Computers are mostly built using components from many different corporations. For this reason, it is easier to focus on specific component advancements. Intel and AMD are the main computer processor companies in the world today and are constant rivals. [42] There are many different personal computer companies that usually sell their hardware with a Microsoft Windows operating system preinstalled. Apple has a wide line of hardware and software as well.
SOFTWARE
''Software'' when I hear this word, one thing comes to my mind.That was computer..And it's through they are connected.Base in my opinion software is one of the important content of computer.I know that people always use it, especially to the student's like me.
Computer software is often regarded as anything but hardware, meaning that the "hard" are the parts that are tangible while the "soft" part is the intangible objects inside the computer. Software encompasses an extremely wide array of products and technologies developed using different techniques like programming languages, scripting languages or even microcode or a FPGA state. The types of software include web pages developed by technologies like HTML, PHP, Perl, JSP, ASP.NET, XML, and desktop applications like OpenOffice, Microsoft Word developed by technologies like C, C++, Java,or C#. Software usually runs on an underlying software operating systems such as the Linux or Microsoft Windows. Software also includes video games and the logic systems of modern consumer devices such as automobiles, televisions, and toasters.

Practical computer systems divide software systems into three major classes: system software, programming software and application software, although the distinction is arbitrary, and often blurred.
System software
System software helps run the computer hardware and computer system. It includes combination of the following:
* device drivers
* operating systems
* servers
* utilities
* windowing systems
The purpose of systems software is to unburden the applications programmer from the details of the particular computer complex being used, including such accessory devices as communications, printers, readers, displays and keyboards, and also to partition the computer's resources such as memory and processor time in a safe and stable manner.
''So like what I said software is important'' without this computer is not complete.

Reflection in Typing Lesson
Instructions
Things You'll Need
- computer with keyboard or typewriter
- 1Get to know the keyboard and which keys to position each finger on. The starting position is called the "home row" position. Here, you put your left hand fingers on the "A," "S," "D," and "F" keys, beginning with your pinky and ending with your index finger, respectively. With your right hand, you place your fingers on the "J," "K," L" and ";" keys, beginning with your index finger and ending with your pinky, respectively. You can consult a chart in a typing book or see the link in the "Resources" section to get more familiar with the home row finger placement.
- 2Practice beginner typing lessons to become familiar with the keyboard. When you first begin, you'll only be typing letters and symbols, not words. At this stage, you're just getting acquainted with using the right fingers for the right keys. You can take typing lessons for free online (see link in "References"), you can purchase a typing software program or you can learn from a typing book such as "Touch Typing in Ten Lessons," "Typing the Easy Way" or Typing for Beginners."
- 3Repeat your lessons as often as possible, but move at your own pace. Learning to type is a complex process and requires you to think about letters and words in a whole new way. Don't move on to a new lesson unless you're absolutely comfortable with the one you're moving on from.

REFLECTION OF BEING A SUCCESSFUL ENTREPRENEUR
A simple entrepreneur is not just okey because you need to improve it until you reach the highest level.To improve it you need to practice those PECs because it is the right way to achieve your dreams . Although many of us have already characteristics of PECs .But some of them don't want to be an entrepreneur,all i can say for them is get that opportunities because i know that you will have a good future in that work.If you don't have those PECs, dont worry because like what i say you can practice it by starting now because ''it's good to be early than late''. Do You Become A Successful Entrepreneur? Now this article definitely is not the be all and end all of ways to become a winner in business online or offline, but some of the points I will make should help you to firmly establish yourself in the world of entrepreneurship, and should hopefully distinguish you from the huge crowd of money-making hopefuls. A take charge attitude. The successful entrepreneur has the initiative and drive, maybe even a compulsion, to run their own show. Even if they were an employee, they wanted to do their thing their way and not be told how to do it. They would take orders, but they preferred to give them. An ability to "think outside the box". While this is probably the biggest clich of our time, it is true. The person who can see opportunities that others miss is at a great advantage in the world of business. Innovations would not happen without the innovators seeing things differently that the rest of us. Must be comfortable with mess. We aren't talking about a dirty desk or messy room here. We are referring to the concept of chaos. Life and especially the business a person starts will throw them many curveballs. The successful ones not only know that chaos and mess will happen, they like it. Genetically gifted with an entrepreneurial spirit. While there is not really a gene for an entrepreneurial spirit, the business person who succeeds seems to be born with this knack for business. Maybe they sold lemonade as a child, had a newspaper route, put on magic shows, whatever. Many entrepreneurs can remember back to their childhood's business endeavors.
