Keyboards Introduction When dealing with computers a user will find it very hard to operate with such hardware as a keyboard. Usually typewriters are the common originator of all key based text entry devices, the computer keyboard is a main use for electromechanical data entry and many of our communication comes largely from the use of these two devices Teleprompters and keypunches. A keyboard is very similar to a typewriter, which is used with an arrangement of buttons that use mechanical levers or electronic switches. Around the 1870’s is when teleprompter type devices started becoming widely used to simultaneously type and transmit data text from keyboards through telegraph lines to stock ticker machines to be duplicated and displayed onto something called ticker tape. Around 1903 to 1910 is when the teleprompter became more contemporary by mechanical engineer Charles Krum and his son Howard Krum. More models were then developed by individuals such as Royal, Earl House, and Fredrick G. Creed. After the decline use of punch cards and paper tape a new type of device came out called a teleprompter which keyboards became the main input device for computers. Because of these devices is how our modern day computer keyboards developed their layouts. A keyboard typically has many characters that are engraved or printed on each key. With each press of a key on a teleprompter it typically represents a single written symbol. Although in order to produce some symbols requires the pressing and holding several keys simultaneously or in various sequence. While most keyboard keys produce letters, numbers, and signs other key presses can produce actions or execute certain computer commands. Hardware development of other input devices such as t... ... middle of paper ... ...ards any character in front of the cursor and the backspace key deletes any characters behind the cursor. Finally you have the lock keys which lock part of a keyboard depending on the settings selected. Most average keyboards have lit up LED’s that indicate which locks are enabled on the keyboard. These include Scroll lock, Num Lock, and Caps Lock. This is all some basic information of keyboards how they were first developed, todays use for them, and the features they possess. Keyboards are one of the main important parts of a computer and without them who know what direction technology could have went in. They allow many communication and data to be transported around the world. Computers are the quickest way to deliver a message or type of communication between people. It also keeps people connected all over and without keyboards we would have no way to do this.
Since the first person heard the wind whistle through the trees or the sea in a seashell humans have been drawn to sound. Being the oppressive and ingenious species that we are we felt the need to capture these sounds and any others that we could to keep for our own. Eventually people like Pythagoras and gods such as Apollo found that by stretching materials and picking/plucking them that they would produce sounds and that the tighter you stretched these strings the higher the sound would go. These were the early beginnings of the pianoforte.
Maybe we need both cursive and typing. But in my opinion as the years sail by technology will catch-up with cursive. But until that day, cursive will still be around. And will be used because there some things computers still can't do yet that cursive can
First, in “The Owl has Flown” Sven Birkerts says “As we now find ourselves at a cultural watershed-as the fundamental process of transmitting information is shifting from mechanical to circuit-driven, from page to
82).” According to Walter Ong, the act of communication through writing heightens ones consciousness and begins to change the way in which the writer thinks. This in turn facilitates the development of increasingly sophisticated technological advancements. Early pictographs were typically monotone and very simplistic in nature. However, as the technology evolved, humankind developed multi-hued writing media that improved the visual accuracy of the images created and subsequently improved the complexity of the message delivered. Essentially more visual detail equals a more complex symbology and abstraction. Some major milestones in the evolution of communication technology include the simplification of earlier literal depictions in the late Paleolithic era, the development of the first “alphabets” as quasi-abstract symbols representing the basic sounds of spoken language. These early alphabets were extremely complex and cumbersome until the Phoenicians developed a “totally abstract and alphabetical system of twenty-two simple phonetic signs, replacing the formidable complexity of cuneiform and hieroglyphs (Higgins, 2003).” The inhabitants of Greece and Rome adopted this system of writing which was in effect by 1500 B.C. and later developed what we know as the

In 2005 the first Black Berry with WiFi was released. One of the first smart phones was the Nokia N95. It had WiFi, a touchscreen and some apps. Then in 2008 the iPhone 3G was released. You could get apps, use a calculator, check calendar, take pictures, call, text, take notes and so much more. Now our phones are very light, and we can do many things with them. You can listen to music or podcast, use social media or play games. Cell phones have also changed our language. Thanks to texting, there are many abbreviations that exist. At first, you could only type 160 characters per text. This caused people to start using abbreviations to use less characters. They also began skipping punctuation. This method became very popular and is commonly used today. The 160 character limit does not exist anymore, but text speak is still very popular. Emojis have also become very popular. Emojis began in 1999 in Japan. To save character limits, they began sending pictures. They only used one character which saved a lot of space. Now, emojis are a new way of communication. Some people only chat through emojis. Some people believe that this could be a new language in the future. Another way cell phones changed the world was that they were
If you ask people to name one of the most important technologies of the twentieth century, one of the answers would most certainly be the computer. A computer, however, is not a technology all to itself. Many other technologies went into the modern home computers of today, including the mouse. Douglas C. Engelbart, a worker at the SRI (Stanford Research Institute), invented the mouse in 1964. However, the process of the invention of the mouse was not instantaneous and without effect on the realm of computing and society. In this paper I will be examining the problems that had to be overcome and the technologies that had to be invented for the mouse to become a reality. It also analyzes the impacts it has had on society and the computer industry.
I can still remember the excitement that I felt the first time I placed my hands on a keyboard. As Neil Postman states, "What is peculiar about such
began to take over the worlds market for tabulators, clocks, and electric type writers. By 1940 it was the us largest office firms that deals with machines. There sales had reach $50 million.
Computers help out hospitals and pharmacies very much. Pharmacists use computers to keep a record of medications and the dosage to give to each patient. Most computers in hospitals are used to keep track of patients and their status. Computers also keep track of equipment placement and their status as well. Scientists depend on computers to help find cures for cancer, STDs, and other diseases. Computer software helps doctors’ research different symptoms, cures and treatments for different diseases. Cures for a lot of diseases would not have been found without the help of computers.
The fist computer, known as the abacus, was made of wood and parallel wires on which beads were strung. Arithmetic operations were performed when the beads were moved along the wire according to “programming” rules that had to be memorized by the user (Soma, 14). The second earliest computer, invented by Blaise Pascal in 1694, was a “digital calculating machine.” Pascal designed this first known digital computer to help his father, who was a tax collector. Pascal’s computer could only add numbers, and they had to be entered by turning dials (Soma, 32). It required a manual process like its ancestor, the abacus. Automation was introduced in the early 1800’s by a mathematics professor named Charles Babbage. He created an automatic calculation machine that was steam powered and stored up to 1000 50-digit numbers. Unlike its two earliest ancestors, Babbage’s invention was able to perform various operations. It relied on cards with holes punched in them, which are called “punch cards.” These cards carried out the programming and storing operations for the machine. Unluckily, Babbage’s creation flopped due to the lack of mechanical precision and the lack of demand for the product (Soma, 46). The machine could not operate efficiently because technology was t adequate to make the machine operate efficiently Computer interest dwindled for many years, and it wasn’t until the mid-1800’s that people became interested in them once again.
While taking a typing course in high school, the hardest part was remembering where each key was. I could never figure out why the typewriter keys were set up in the order they were, but once I learned the various keystrokes, it became second nature to type. Although, I still have trouble with some of the keys on the top row, such as numbers and symbols. This is probably because they aren't used as much as the others. Another difficult part was remembering to hit the return key when I wanted to go to the next line. Setting the tabs and margins properly could also be quite trying. Never in my wildest imagination could I have envisioned a typewriter that could wrap-around to the next line, automatically set margins, and even tell you when words are misspelled or used improperly. Now I know that there is no limit to what computers will be able to accomplish in the future. It will only take imagination and determination to make them do whatever we want them to do.
In 1937 the electronic computer was born. Computers were in 1943 to break “the unbreakable” German Enigma codes. 1951 introduced the computer commercially. However, it wasn’t until around 1976 when the Apple II was introduced and it was immediately adopted by high schools, colleges, and homes. This was the first time that people from all over really had an opportunity to use a computer. Since that time micro processing chips have been made, the World Wide Web has been invented and in 1996 more than one out of every three people have a computer in their home, and two out of every three have one at the office.
Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing. Although one can create a typed paper with a typewriter, the computer has more features
First of all, the computer’s role in society has increased significantly throughout recent years. In the past, a computer was mostly used for minor tasks, such as typing a paper or playing a game for leisure. A child could rarely be found sitting in front of a monitor screen, and they usually didn’t even know how to operate the machine. Software games were on the market, but were not very popular for purchase. Usually the more developed households and higher-class families were the ones that contained a computer at home, but mostly adults were found to be the users. Many families found it easy to do without one, as they were mostly used for typing, and typewriters or handwriting took their place. In the past, computers went without the Internet, were extremely slow, and weren’t capable of much of anything.
