- Typewriter: Main Triggers
This is the forerunner of the electronic device with buttons letters and numbers driven by suppressed. In its development, the typewriter had many innovations since the first appearance in 1714 in England. A British man named Henry Mill filed a patent for a machine called an "artificial machines that copy the letters one by one to the letter".
However, the first typewriter really complete is made Pellegrino Turri of Italy in 1801. He made this machine devoted to the Countess Carolina Fantoni da Fivizzano a blind patient. Machines that are needed by these authors undergone various changes again to the American inventor, Christopher Sholes have created practical modern typewriter in 1866, which uses a standard keyboard 'QWERTY'.
This arrangement of letters as suggested by James Densmore, a business associate Sholes, with the goal to separate each key is often used to typing process is not stalled. Until now, the layout of the QWERTY keypad on the keyboard is still used throughout the world for laptops, PCs, mobile phones and other gadgets.
- Personal Computer: Advanced Starters.
From the typewriter used by electronic typewriter came the more sophisticated tools to monitor and separate keyboard known as the Personal Computer (PC). Initially, the precursor of the PC used to be called Microcomputer is only purchased by U.S. electronics hobbyists and technicians alone in the 1960's. The term 'personal computer' itself appears the first time on 3 November 1962 in an article published in the New York Times.
Microcomputer underwent numerous innovations in the hands of the experts and finally technology company IBM (Internation Business Machines) introduced the use of PCs for home, office and school on 15 November 1971. Within a year, IBM initially sold 2 million units, capable of soaring to 5.5 million units. In the early 1970's as well, the company Hewlett Packard introduced fully computer program that can be placed on the table, complete with keyboard, monitor and printer display. Then in 1976, the American duo technical genius, Steve Jobs and Steve Wozniak created the first color computer they named Apple.
In its development, the PC is found in various forms, software, technology and diverse applications.

- Laptop: Appears For Practicality.
Personal computer or PC also continued their trend toward a smaller size. From the computer that can be put on the table (desktop computer) to a computer that can be put in a bag or often called a laptop. History of laptops that use rechargeable batteries can be traced back to the 1970's. At that time, the technology expert, Alan Kay of the Palo Alto Research Center achieve its mission of creating a computer that can be portable, do not need to use cables and small. Minicomputer was then named Dynabook.
Dynabook was later developed into a laptop computer that is shaped like a folded book, where the top of the screen and is part of the keyboard is laid flat. Initially laptops were already using LCD (Liquid Crystal Display) has a size of 10 inches to 17 inches. Although a bit heavy, large laptop has the advantage that being able to play CDs or DVDs.
Now the laptop can already be found in smaller sizes often called netbooks. This mini laptop weighs sekit 1-6 pounds, depending on size, materials and specifications in it. Later in 2011, the company developing the technology Intel Ultrabook, which is a laptop the size of a very thin, less than 2 cm and is unbelievably light weight, less than 1.5 kg.
- Tablet Computers: The Efficient Small
Comes the latest innovation known as a tablet computer, a portable computer complete the entire form of the touch screen panel. Unlike a laptop that has keyboars, tablet with a touch screen system uses a stylus, digital pen or fingertip us to operate. The first tablet computer was released by Microsoft company in 2000 with a version of Windows XP.
However, the successful popularization of computers Apple tablet is the company that launched the iPad version of his creations in the form in 2010. Followed by Galaxi Tab tablet launched by Samsung. This new tablet computers increasingly popular with the Linux-based Android operating sisters that allows users to create their own applications. Tablet sizes began to vary from 7 inches to 10 inches can be held by hand.
