Laptops vs. Desktops Essay

Designed to be a static unit, desktops are usually much heavier and larger than laptops or netbooks. However, this allows for them to be comparatively faster and more powerful than a similarly priced laptop. If you need or want power on a budget and do not need to work on the move regularly, a desktop is a great choice. The extra power possible also makes desktops a good choice for gamers and media creators, too. The design of most desktops also makes it possible to upgrade units with more memory, higher powered graphics and sound, and more processing power, if you know what you are doing. This also means that many hardware malfunctions - if you are unlucky enough to experience any - can be fixed simply for the price of the part and labour.

The ‘ENIAC Story’ is a historical account of the creation of the world’s first electronic digital

From a very simple invention satisfying man’s conviction to do better, the abacus dramatically encouraged the growth of trade wherever it was adopted, for it was well suited to any commercial calculation. Still used in the Soviet Union and in the Far East in the 20th century, the abacus was finally replaced worldwide by the cheap electronic calculator. (The Inventions, pg.10) In 1945, the world’s first fully electronic computer was completed at the University of Pennsylvania. It was called ENIAC-Electronic Numerical Integrator And Computer.

The 1940’s was the beginning of an era of computers ruling us. It all started with Konrad Zuse a German engineer creates and finishes the computer called Z3 built in 1941 it was built using 2,300 relays, and used a floating point binary arithmetic, and had a 22 bit word length. Although the original was destroyed in a bombing run in Berlin in late 1943. He supervised a reconstruction of his invention in the 60's which is on display at the Deutsches Museum in Munich. In February of 1946 the ENIAC was released and the public was able to view it, built by John Mauchly and J. Presper Eckert they improved it by 1,000 times since the first computers were released. Started in 1943 it took 3 years to complete and it used a plugboard and switch program, and the speed was about 5,000 operations per second. It took up 1,000 square feet, or the size of a small house! In 1944 the Harvard Mark-1 was completed. Thought by the Harvard professor Howard Aiken, and built by IBM, the dimensions of this beast was room sized, relay-based calculator. Also it had a

The origin of the computer resides with the military. The computer itself was created by the military during the Cold War era, when we were in a technological race with Russia. This race was the fuel for massive advancements in technology especially in the sector of computer intelligence. The first Computer’s were physically large enough to fill an entire room. They were used to manage large quantities of data in textual and numerical form. The government backed certain research facilities in the advancement of the computer and some investigated and experimented in computer technology with art and music. 1

The ENIAC was invented by John Mauchly and J.Presper Eckert, Jr.and built from 1943-1945. The ENIAC (Electronic Numerical Integrator and Calculator), often referred to as the first computer, was built to supply the need for faster calculations. It started the information age and led to the development of the first commercial computers (The ENIAC).

When ENIAC was announced in 1946, it was heralded in the press as a "Giant Brain." [8] It had a speed on the order of one thousand (103) times faster than that of electro-mechanical machines; this computational power, coupled with general-purpose programmability, excited scientists and industrialists

Every since I was a child, computers fascinated me. I wondered how a computer can display pictures and words very quickly onto the screen. Who invented the computer and how can all of the websites and applications work? It amazes me how many programmers program applications in order for the world population to use on a daily basis.

The computers were interactive and used voice control as well as keyboard. It was all state of the art, no one was aware that contemporary science had come this far in regards to quantum computing. Many of the major universities throughout the world had been working on quantum computing and it was believed it was in its infancy. NASA had been working secretly quantum computing for many years and kept their findings to themselves while building generation after generation of the computer to what the finally have now, it was an amazing piece of

ENIAC stands for Electronic Numerical Integrator and Computer. It was introduced on February 15, 1946 and was the very first digital and electronically run computer. It was created in the United States at the University of Pennsylvania and its original purpose was to calculate artillery firing tables during World War 2. The ENIAC weighed 30 tons and filled up an entire extremely large room with its many parts. Its complexity was prominent, containing approximately 18,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, thousands of switches, and 1,500 relays. It produced calculations that, if done by hand, would have taken much longer to achieve. For example in one second, the ENIAC could solve 5,000 additions.

The ENIAC was the first computer to ever work successfully. ENIAC stands for Electronic Numerical Integrator and Computer but for now we will call it ENIAC. The ENIAC’s design and construction was funded by the United States Army and the total cost was around $487,000. The basic machine cycle was 200 microseconds or 5,000 cycles per second for operations on the 10-digit numbers. In one of these cycles, ENIAC could write a number to a register, read a number from a register, or add/subtract two numbers, several tubes burned out almost every day, leaving it nonfunctional about half the time. Special high-reliability tubes were not available until 1948. Most of these failures occurred during the warm-up and cool-down periods.

The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the

In between 1943 and 1946, ENIAC was designed by John Mauchly and J. Presper Eckert at University of Pennsylvania, U.S. ENIAC was a modular computer, collected of separate panels to perform different functions. Twenty of these parts were accumulators, which could not only add and subtract but hold a ten-digit decimal number in memory. Numbers were passed between these units across several general-purpose buses. In order to achieve its high speed, the panels had to send and receive numbers, save the answer and produce the next operation, all without any moving parts. Key to its usefulness was the ability to branch; it could produce different operations, depending on the sign of a computed result. ENIAC contained 17,468 vacuum tubes, 7200 crystal diodes, 1500 relays, 70,000 resistors, 10,000 capacitors and about 5,000,000 hand-soldered joints. It weighed more than 30 tons, was roughly 2.4m × 0.9m × 30m in size, and consumed 150 kW of electricity. This power requirement led to the rumour that whenever the computer was switched on, lights in Philadelphia dimmed.

ABSTRACT Computers and laptops are most important in higher education. Now a day’s most of the universities are preferring laptops for using in classrooms. Laptops are very useful in many things like information gathering, data saving…etc. When compared to desktop it is easy to carry and we can perform the task quickly by using the laptop.
