Computers Components and Technology

A computer is compared to a calculator; used to increase the speed and accuracy of numerical computations–the abacus and more modern mechanical calculators (dating back more than 5,000 years ago–using rows of sliding beads or mechanical rods an gears to perform arithmetic operations. However, even during the nineteenth century calculators were very commonly used for calculation, but they were not considered computers.

A computer is defined as a mechanical or electronic device that can efficiently store, retrieve, and manipulate large amounts of information at high speeds and with extreme accuracy. Additionally, computers are built to perform and execute tasks, while accommodating intermediate results without human intervention. This is achieved by the computer utilizing a list of instructions called a program.

History: Computers and Technology

An Englishman, named Charles Babbage, designed and assisted to build an absolute computer during the mid-1800s. This machine–the Analytical Engine–was composed mechanical axles and gears by the hundreds. Ultimately, this design was obtuse in sorting and processing 40-digit numbers. Also, because of Babbage’s engineering venture, an Ada Agusta Byron–the daughter of a Lord Byron of those times–took the reins and exploited this invention. In relation, a primary program was labeled Ada. Moreover, unfortunately for Babbage’s work, the project was complete as it was considered detrimentally complex for the technology of those days. Thereafter, computers were put on hold for a while.

Seventy years after Charles Babbage’s death, computers became of importance to certain professors and scholars of the early twentieth century. In fact, two masters from Iowa State University–John Atansoff and Clifford Berry–along with Harvard University’s Howard Aiken took interest in completing computer projects. However, their ideal success wasn’t very true. Labeled as having intermediate results, the Atansoff-Berry project did actually operate–requiring multiple interventions by the operator while in use. And Aikens’s Mark I simply did not perform independently.

VACUUM TUBES AND TRANSISTORS

Vacuum Tubes–ENIAC: Electronic Numerical Integrator and Computer

Furthermore, a few years later, led by the infamous J. Presper Eckert and John Mauchly–of the University of Pennsylvania–achieved the developments of fully functional electronic computer (the ENIAC). The ENIAC became a large attribute regardless of its huge appearance; 80 feet long; 8 feet wide; weighing 33 tons; comprised of 17,000 vacuum tubes that were included in its circuitry–consumed 175,000 watts of electricity, while executing computations of 5,000 additions per second. Next, the vacuum tube intervention last for a sound decade, as great computer kings–IBM and Remington–adopted the concept; acquiring a mandated climate-controlled environment attained by large businesses, university systems and primary government agencies.

Transistors

The enforceable excitement of the vacuum tube began to dissipate after the impressive details of the transistor came about during the 1950s. Although the run with the vacuum tube was a beneficial hit, because of its reliability and contributions to computer speed, the transistor took their place on the prize rack. Transistors, for the most part, were the changing point in computer technology of the twentieth century: Small and energy-efficient. Nobel Prize winners–William Shockley, John Bardeen, and alter Brattain–influence the design and development of the transistor that resulted in an ideal that was hosted by Bell Labs in the late 1940s. Ultimately, transistors were commonly packed into compact enclosures that were housed in order to expand the idea and development of successful integrated circuits; which were commonplace in minicomputers, and complied into the much larger mainframe computer.

The Need of Cloud Computing in Web Business and The IT Sector

Cloud computing deals any subscription-based or pay-per-use service that, in real time over the Internet, extends IT’s existing capabilities. Cloud computing technology provides on-the-fly, point-and-click customization and report propagation for business users, so IT doesn’t spend half its time making minor changes and running reports.

Cloud computing technology is tripping a huge change in application development circles. As a metaphor for the Cyberspaces, “the cloud” is a everyday cliche, but when combined with “computing,” the meaning gets large and furrier. Today, for the most part, IT must jade into cloud-based services individually, but cloud figuring aggregators and integrators are already emerging. One potential security implication of cloud computing is that if you have individual data in that cloud, you are sharing hardware/networks with potential competitors in rather close propinquity, which is why for some folks building “clouds” they look to be for the most part just virtualization-heavy internal deployments. Cloud-based tools can be up and working in a few days, which is silent of with sanctioned business software.

Increasingly, IT squads are turning to cloud computation technology to minimize the time spent on lower-value natural actions and allow IT to focus on essential activities with greater impact on the business.

The cloud computing infrastructure not only provides deep customization and application configuration, it preserves all those customizations even during upgrades. By their very nature, cloud figuring technology is much better and quicker to incorporate with your other enterprise applications (both sanctioned software package and cloud computation infrastructure-based), whether third-party or homegrown.

By eliminating the problems of traditional application development, cloud computing technology releases you to focus on developing business applications that deliver true value to your business (or your customers).

The Upsides and Downsides of Computer Development

The great thing about computer technology is that due to its speed of development the prices of computer, laptops and peripherals such as scanners and printers become less expensive. The down side is that the technology is developing so fast that computers become out of date very quickly. In the past you could expect a high spec computer to last you a good 5 years or so as long as you looked after it. However, today a high spec computer or laptop that is 2 years old is considered an antique. This means that you have to keep changing regularly to keep up with the new technology and power hungry software applications.

Many computers that are built with the basic components and hardware to perform general word processing and web surfing will soon become redundant as software applications that include Microsoft office will require more RAM space. Many low spec computers will soon not have the processing speed or memory to function and operate efficiently. The load up times will become slower and blue screen crashes will become more frequent.

Although it can be costly having to replace your computer every few years there are alternative ways that you can acquire new computers in a way that is more affordable. One way is to rent a computer. This method of paying for a new computer is becoming more popular. When you think about it, it makes sense because new computers are becoming outdated more quickly. The idea of spending a lot of money on a computer for it to become out of date makes renting one far more attractive. The great thing about renting is that you can rent the latest models for a year and then exchange it to rent a newer model. In this way you can keep on top of technology without having to spend the full price each time you buy a computer outright.

News From the World of Social Media, Computer and Technology

Due to the latest innovations, the world has changed into a global village and has brought many changes. In this respect the internet has paid much contribution, not to mention social media like twitter and Facebook which has really altered and affected our lives.

Twitter being one of the best resources for finding breaking news and information, with more than 200 million accounts, has flourished in recent years. In December 2011, a new version of Twitter was launched, available for mobile phones, iPhone and Android. Anyone who has access to it can click any tweet in his/her timeline to expand it to see photos, videos, favorites etc. and can ‘discover’ and plunge into a stream of useful and entertaining information which are based on his/her current location, what he/she follows and what is happening in the world.

Another social-media, Facebook also enables users to share stories on their profile pages and update their status. In accordance with the latest updates, Facebook has now rolled out a way for its users to edit and re-write their comments, simply by a click on “edit or delete”.

Moreover, Facebook has issued a new email for its users, replacing their primary email accounts, like Yahoo or Gmail with a Facebook.com account.

Computers have taken over every aspect of human culture. We use computers to work, play, do research, shop, stay in contact with friends, and more. The name which has ruled the whole computer world since its first launch in November 1985 is WINDOWS. It is the most used operating system in the world. But another technology of operating systems is coming ahead which will fully replace windows, named as MIDORI. The main idea behind it is to develop a lightweight portable OS which can be easily joined to various applications.

New computer technologies keep coming out continuously and nearly everyone wants to keep up with the latest computer technology that comes along. For example, laser printers have taken the place of ink-jet printers; auto makers are appealing to car buyers with new in-vehicle technology like LTE, digital review mirrors and advanced telematics systems.

There have been more inventions such as Robots with human expressions, 4 G Technology, 3-D Processor chips and latest phones. It is said that in the near future we will see holographic cell phones replacing the simple cell phones, enabling the user to walk next to a hologram of a friend or colleague.

According to a current research, Robots of future will develop the ability of generalization and will learn to manipulate objects. This will help them to adapt according to new environments. Making robots like these is a giant leap in robotics.

Defense Advanced Research Projects Agency (DARPA) of United States has developed an unnamed aircraft which can stay in air for a period of 5 years at a time. It is one of the most recent inventions in technology of the world.

Technology and Elderly – Embracing Technology to Improve Your Life

Technology is normally associated with the young and the trendy. Cell phone and computer companies market the gaming and music abilities of their phones and computers. The phones come in fashionable colors with hip ringtones and flashy features.

Older people are seldom interested in all this, but the basics of technology, without all the extras, can come in very handy for older people. The elderly of today didn’t grow up in a time where technology was as essential as it is today. They are scared to experiment and use technological devices such as computers and cell phones. That said, there are many elderly people who are quite competent in using their cell phones and computers but they are in the minority.

Technology can add to the comfort of the elderly and it can allow them to stay independent for much longer. The explosion in the technological device market has been phenomenal. If you can think of something to make your life easier and more comfortable, you are almost certain to find it.

While many of these devices might be unaffordable to a lot of elderly people, a basic computer and cell phone is within reach of many elderly people’s budget.

A cell phone is a wonderful device that allows older people to stay in contact. There are cell phones on the market with bigger buttons and screens that make it easier to use. Sending text messages is a daily occurrence in almost everybody’s life. Staying in contact with loved ones and family or friends is very important in older people’s lives. Receiving a message from a loved one can brighten up a lonely person’s day.

The advantages of computer technology to the elderly are more important than what most people realize. What is there that you can’t do over the internet? Elderly people can be in control of their own finances by using the internet banking services. For someone who finds it difficult to walk or stand in queues, internet banking is a wonderful tool. The elderly person won’t have to rely on others to get to the bank and they won’t have to go through all the distress of actually visiting the bank. It won’t only have an impact on the elderly person’s life, but also on those responsible for driving them around and assisting them in these tasks. Many online shops provide an online grocery ordering and delivery facility as well.
