Notebook Computers
Imagine working on your English papers sitting comfortably on your couch in front of the TV, or working outside on a beautiful day. This dream could be a reality for those who purchase a notebook computer. Today's notebooks have just as much computing power as desktop models but are more compact, and with wireless internet access are now more portable than ever. This paper will give a brief history of notebook computers, explain how they work, and compare a couple models.
First Notebook 1979
Notebook computers have been around longer than most people would realize. The first notebook was designed in 1979 by William Moggridge of Grid Systems Corporation. It was one-fifth the weight of any equivalent desktop model and was used by NASA on the space shuttle in the early 1980s. Apple Computer introduced its first notebook-sized computer in 1984. Although the Apple IIc was genuinely a portable computer it was not a true laptop. The actual computing system weighed about 10 to 12 pounds total, but the monitor was heavier than the computer itself. In 1986, IBM introduced the first compact computer small enough to be called a laptop, the IBM PC Convertible. It weighed 12 lbs and sold for $3,500. The PC Convertible was a success, and ushered in the laptop era.
The major aspects of notebook computers are the same as desktops. They contain processors, operating systems, memory, disk drives, input/output ports, sound cards and speakers. The “brain” of the notebook is called a “microprocessor.” It coordinates all of the computer's functions according to programmed instructions. The operating system, such as Windows 98/2000/NT/XP, Linux and Mac OS, is the set of pre-programmed instructions that tell the processor what to do. Notebooks contain both RAM and ROM memory. ROM stands for Read Only Memory. It can be read from, but not written to. ROM is where the basic input/output is stored. RAM is the memory that stores application software and data files while the computer is operating. In order for notebooks to be more portable and durable than a desktop, the memory modules have to be different.
This memory is assists in allowing the computer to simultaneously read and write data at the same time. Simply put, RAM is the most common form of memory that is utilized by computers as well as other devices. There are specific types of RAM that include dynamic random access memory and static random access memory, or DRAM and SRAM respectively. These two RAM are very different in terms of how they allow data to be read and written. Dynamic random access memory is often considered the most frequent type found in computers. Static random access memory is also found in computer, and is usually referred to as the faster of the two types due to the fact that refreshing of this form of memory is not needed whereas with dynamic random access memory it is. The term RAM is often used to describe what the computer uses to function. It is the main memory or primary memory whereby all processes and software run. Since it is random access memory, it is only available at the time a certain process is needed and is not stored anywhere on the computer specifically (2007). This is what makes random access memory often confusing to understand particular since computers also have what is known as read only
Although it is often argued that rulers such as Joseph II, Catherin II, and Frederick II were motivated to instate enlightened principles; oftentimes, these rulers were slaves to the ideals of despotism, where the preeminent goal was to obtain more power. Indeed it may be a legitimate claimed that these rulers realized the greatness of Enlightenment ideas; however, since most of their reigns were spent preserving dominance over their people, it is safe to say that these individuals may have been more dedicated to serving their own self-interests.
Hewlett-Packard (HP) is a technology leader in United States and the world. It was founded in 1939 in Paolo Alto, CA by two Stanford graduates Bill Hewlett and Dave Packard. Forty five years later another student Michael Dell in Austin, TX found another company that will essentially become HP’s biggest competitor. These two companies are pushing each other in developing new products and services to its extremes in attempt to capture bigger market share and increase profit. Strong competition is the biggest reason for tiny profit margins in this industry. Both companies use strategy that they think is the right for the given moment. We will analyze strategic moves that both companies made recently or are still making.
Tablets are effective tools used to improve user’s productivity and online experience, whether they are used for business or life in general. Tablets are smaller than a laptop and larger than a Smartphone, so they are perfect to take on the go. Users can browse the internet, create presentations, stay connected with their boss, download games, watch movies, share photos and much more with their tablets. Just recently tablets have become very popular. Therefore, there are over 47.5 million tablets sold in the United States today. Two of the most popular tablets on the market are the Apple iPad and the Amazon Kindle Fire. Evaluating their battery life and capacity, screen size, and price, a user will soon figure out which table is best for them. Though each of them had good qualities, I preferred the iPad more than the Kindle.

To be able to make an effective entry into this market, we as Toshiba are looking for markets where there is still a high competition and where Compaq/HP did not gain such a high market share. This is the reason, why we plan to launch our new product in Turkey, where there is a high potential of success for our new device, the Toshiba E800 series. We know that we can answer to the requirements of a wide range of costumer in Turkey, where the interest towards PDA is as high as the rest of Europe.
During the Enlightenment period literacy rates and intellectual thinking grew tremendously. People from all classes began to question authority and challenge it. They realized royals were ordinary people like themselves. They questioned the divine right to rule, kings
The universe is an unknown place. Most of it has not been explored. Some things are known, however. Scientists know a lot about things like the Big Bang and our Asteroid Belt. Some of the universe's natural phenomenons are yet to be discovered. This article will explain some of them and why they happen.
Although the Osborne Corporation's business practice may not have been the best, they are still responsible for introducing the world's first portable computer.
Technology has greatly evolved over the centuries. Machines have been aiding man to ease their work, fight in wars, travel, health, and different aspects of life. Telling time, keeping up with friends, finding information, and many more have never been easier with the making of the computer. The computer has evolved over the decades becoming the need by many people. Students have used computers, laptops, and tablets to help them with their academics. Having such technology seems to be de rigueur in the past years. The Macbook Air and the Ultrabooks are one of the new laptops of 2013. The former was first introduced on January 15, 2008, while the latter was introduced on October 2011.
However some monarchs accepted the philosophers ideas and were inspired by them to implement reforms that benefit the entire nation. One of these was Frederick the second, known as Frederick The Great, the king of Prussia who saw himself as the “first servant of the state”. During his time the use of torture was reduced and free press was allowed. Additionally he tolerated religious differences and welcomed victims of religious persecution. This influenced people who lived both in Prussia and outside of it because they now had a county who welcomed them regardless of their religion beliefs. Another important Enlightened despot was Maria Theresa who worked to improve the life of peasants. Her son Joseph the second, also known as the most radical of the enlightened depots who supported religious equality for Protestants and Jews in his Catholic Empire. He allowed freedom of speech and ended censorship to give people the opportunity to express and spread their ideas. This influences peoples way of life and the life standards rose to some extent. People could feel more secure and treated more like individuals instead of as an entire mob. Changes were happening slow, but slow changes are better than no changes so it was still a step towards a more just society where people would be more equal than they were before. The
The First Generation of Computers The first generation of computers, beginning around the end of World War 2, and continuing until around the year 1957, included computers that used vacuum tubes, drum memories, and programming in machine code. Computers at that time where mammoth machines that did not have the power our present day desktop microcomputers. In 1950, the first real-time, interactive computer was completed by a design team at MIT. The "Whirlwind Computer," as it was called, was a revamped U.S. Navy project for developing an aircraft simulator.
The laptop and cell phone are two pieces of technology used worldwide that offer a variety of employments. Along with communication, these two similar devices share many of the same qualities such as gaming, conducting research, and easy accessibility; nonetheless, they do not share all similar qualities.
In 1984, the same year that Compaq introduced a PC that included Intel’s new and more powerful 80386 class of microprocessors, beating IBM to market and Michael Dell began building IBM compatible computers in his college dormitory, Lenovo was form as a shop in a small concrete bungalow in Beijing with a mandate to commercialize the Academy’s research and use the proceeds to further computer science research.
This is probably the greatest discovery imaginable; however, the universe still seems to be a very controversial subject.
