Computer Printer Technology

The computer printing technology that is used today is a far cry from that which was first used at the dawn of the computer age. Many of the older technologies are now obsolete, although they were at one time in widespread use. Other newer print technologies have replaced them and the way forward is forever changing as new computer print technologies come to the fore.

Obsolete Printing Technology

As time has passed and the computing powers of modern day PC’s have changed there has been a huge advances in the fundamental printing systems used by computers. The print technologies listed below are now obsolete, but did at one time play a large part in the computer printing industry.

Typewriter
In the early part of the evolution of computer printing there were a number of computer printers that were simply computer-controllable versions of current electric typewriter technology. These computer printers coul “type” faster than humans at averaged a speed of 15 characters per second.

Teletypewriter
One of the most popular computer printers of its time, this type of printer could be easily interfaced to all non IBM computers. Teleprinters were a little slower than typewriter printers and averaged about ten characters per second.

Dot-matrix
The original dot-matrix printers were extremely popular computer printers during the 1980’s. They were able to produce not just characters, but also images although be it of a lower quality. There were two types of dot-matrix computers available at this time, namely:

– Ballistic wire printers
– Stored energy printers

Did you know? Some dot matrix printers could be upgraded to print in colour. This made them extremely popular for both home and office use during the 80’s.

Modern print technology

There are a number of modern printing technologies that are used today in both home and office printers. Although the list below does not include all of them it does include the most important and well known modern computer printing technology:

Toner
Toner printers include both laser printers and LED printers. As with digital printers they use a xerographic printing process.

Liquid inkjet
Liquid inkjet printers print by propelling different sized droplets onto the printing surface (paper). This is the most common of all modern home and small office printer types.

Merging Technology and Child Development

And while it is recognized that technology, particularly computers are not supposed to replace basic human interactions and relationships, many studies have been undertaken with respect to the role of technology in the social, cognitive and language abilities of the child. They have also been recognized as important tools that aid in the learning process and growth of the child.

Computers are used to enhance language development of the child through computer-based readings and materials that allow for more interaction on the part of the child-learner. Children find it easier to learn their alphabets with the aid of recorded voice pronunciations in the computer and interactive images and pictures that they can manipulate. Computer programs that allow for more manipulation and interaction have been found to make a contribution to the development of the child’s imagination, exploratory skills and logical thinking. As children are basically psychomotor learners and are attracted to visuals and colors, computer programs, the television and video discs have become essential tools in the delivery of the average pre-schooler’s lesson. Children exposed to computers were also found to have good eye-hand coordination.

Technology has been found to play a part in raising a child’s self-esteem and self-reliance. There is also evidence to suggest that using technology increased children’s confidence, comfort, and familiarity with technology at an early age. Similarly, children who were exposed to computers and technology-assisted instruction were found to be more work-focused and more productive compared to children who had not had this experience.

Technology now plays a crucial role in the development of children with learning disabilities. The use of hearing aids and computers have helped these children in word recognition, reading and writing because lessons can be programmed so that they are adaptable to the needs of the individual. In addition to this, the virtual, interactive world of the computer is now becoming a place for social interaction among children with language and speech disabilities.

In many respects technology has become the answer to the growing concern of psychologists about multiple intelligences and the different patterns of growth and development of the child. The use of technology and the computer mean that activities can be specially designed to address the needs and interests of children. The use of television and video discs have also broaden children’s knowledge of the world and their conceptual understanding of traditions and cultures other than their own.

Some people have complained that this is an ‘overuse’ of technology that could lead to negative effects such as the development of a sedentary lifestyle and obesity. However over exposure to the television or computers can easily be addressed with the use of proper guidelines and monitoring of use by parents and teachers. The maximum amount of screen time should be one to two hours a day for young children. Parents and teachers should still include a variety of physical activities and play in the course of a child’s day. Parents should take notice of, and monitor the software and programs that their children can use because not everything on the television or the internet is suitable for children.

We should not be too quick to discount the possibilities and opportunities technology can offer to the development of our children. These things have a role as learning tools but it should not be forgotten that in the child’s formation of his or her self the human role which facilitates more interaction on the part of the child learner is indispensable.

Computers and Home Owners Insurance

It is a fact that technology has changed our lives in a radical way. Not so long ago, when computers were first created, they could easily take up a whole room. Technology has risen in such a way that it seems to have no limits. It is unbelievable just how it has changed. Currently, almost every home in the US has a computer – and some even have more than one.

Nowadays computers and technology have helped us advance from what looked almost impossible years ago. Computers have really changed our lifestyle. We don’t need to move from our homes to do some activities such as banking, shopping, paying bills, chatting with friends, or working. Business and recreation have changed thanks to technology.

With the help of computers and technology, you can also search for and purchase home owners insurance online. Any type of insurance can be purchased on the Internet: health, life, automobile, and even homeowners insurance. No matter what kind of insurance you are looking for, you are more than likely going to find it on the Internet if you search. Today most insurance companies are using the Web, and new companies are even springing up just to do business through the Internet.

But the Web can also be dangerous. Home owners insurance is something important. Before purchasing this kind of insurance on the Internet, you need to do some research. Once you have found some insurance companies you could be interested in, you should find out about them. Try calling the customer service and ask questions. You could also call your state’s insurance bureau to verify the validity of the respective company. Technology has changed for good, but you must be really cautious about the way you use it so that you always make informed choice!

Computers and Cheap Watches

There are tons of expensive watches out there that cost hundreds or even thousands of dollars. The majority of these watches are all classic, mechanical pieces that have so many features it makes telling time incredibly difficult. What is the point of spending all that money for something that is not even going to serve the intended purpose? That is why one should greatly consider computer powered, cheap watches, also known as digital watches.

Although many digital watches have a very low cost, there are many out there that can be almost as expensive as traditional watches. If you want a watch to look classy, then there is no point in shelling out tons of cash for a good looking digital watch, so those should be avoided. If you want to save money, then a digital watch is perfect for you. You can get a fairly decent digital watch for between twenty and fifty dollars, and there are some out there that are as low as ten dollars, but the quality of said watches is very low.

Digital watches are great because they cost so little and serve the purpose of a watch exceptionally well. With a traditional watch, it can be somewhat difficult to tell the time, at least at a moment’s notice. Digital watches enable you to look quickly down at your hand and know the time right to the second, as long as the time you set it to is accurate.

As computers and technology become more sophisticated, so will digital watches. Already at this point in time, there are many watches that have features that used to be found only in decades old computers. Thinking about that, it is amazing to think how far we have progressed. Who knows, perhaps we will be playing three dimensional games on our watches in just a few years. With the way things are going, that is not too far out there.

Computers and Society

People have come to depend on computers and technology for almost every aspect of their lives, and there is hardly anything that is not impacted by their functionality.

Let’s look at some of the things that we have in common with computers. You will be able to identify and relate to the uses which we all tend to accomplish on our computers.

People love to play video games on their computers more than anything else, and proof of this is that almost every single pc out there has games on them. They can also be online, where millions and millions of people play together every day.

Get online and see how many games are out there that involve playing with other people. You will be amazed at how awesome and engaging playing live games with people can be. You will be joined by millions of other users in games that cover almost every interest and category.

Social networking is something else that is a product of computer technology, and it is changing how the world stays in touch. You can do things never before possible, like share pictures and movies, along with writing notes and stories with people in real time from all over the globe.

Looking for a particular song or obscure film? The internet is the place to find it, instantly and effortlessly. No more going to the video store in the middle of the night, because you can search, download and watch or listen to your favorite music or videos in real time without having to do anything.

How we do business is changing because of the computer as well. Can you think of anything that hasn’t been effected by technology? How we earn and spend money, shop, learn and even travel has been impacted by computers and the world relies heavily on them to get the job done.

Lastly, the computer makes it possible for you to talk to almost anyone on the planet for free from the comfort of your home. It has completely revolutionized how we stay in touch, and the options that we have in order to do so. From online phone calls to video conferencing, communicating now is not like it was when we had to make phone calls or write letters.

Safeguarding Information Security

Undoubtedly, Information technology has become increasingly important. It has become a part of the day-to-day operations of businesses, companies, government and non-government organizations. Daily living of an average individual involves computer and technology: communication, e-commerce, online banking transactions and other financial and work-related activities. Companies, entrepreneurs and small and medium enterprises have become more reliant on information systems to support and deliver diverse and complicated business processes which include accounting, inventory, marketing, payroll, research, sales tracking and even remote business operations that involve real-time surveillance.

There have been fair, satisfactory and even excellent results brought by information technology. The general public has been clinging to what one might consider as the perfect solution to an ever-increasing demand of complex processes of problem solving that delivers fast and reliant results. Indeed. But the jubilation is not absolute. As information technology has become prominent in its importance, so does the threat that comes with it. Despite the advancement of information technology, security and privacy have become an increasing pain in the ass. While superior information technology system has been built by the experts, maintaining its security has become harder for administrators and end-users. Today’s users have become increasingly wider- ranging from vast majority of employees in many companies and organizations and a huge fraction of households all of which are exposed to security and privacy threats.

Majority of the security features are a hassle and awkward to use and can present a great obstacle to use in getting work done in such a desired pace. As a result, internet security measures have been bypassed, disabled or ignored too often. Subsequently, when security gets in the way of functionality, end-users tend to disable the very security features that protect them from cyber threats. The result is that they often engage in actions, consciously or unconsciously, that expose them to these cyber threats while compromising system security and exposing sensitive and confidential or personal information.

Privacy tools and software have become increasingly difficult to use. Over the course of time, as cyber threats have become increasingly vast and complex in operation, the very core of the tools that are designed to protect end-users have become user-unfriendly, difficult to understand by an average user and a bit expensive to avail. These factors have contributed greatly in the end-users decision of ignoring protection tools that puts them at risk to cyber threats.

Computer technology must be geared towards protecting its users. Privacy and security software developers must come up with a protection model and features that do not interfere with system usability. They must come up with tools that are efficient and cost-effective. Web designers and developers for banking and e-commerce must triple their standard in making these websites secure and infallible of threats.

Of Computers And The Medical

Computers and technology have long played a role in the medical system. In more recent years, however, computers have started to become an increasingly relied upon method for helping to keep patient records straight and for keeping people healthy. In fact, the use of computer sciences combined with the information sciences in the medical field has become so prevalent that a term has been developed to describe this merging of fields: health informatics.

Health informatics, also referred to as medical informatics, focuses primarily on the use of computers and information science to help acquire, store, and retrieve information in both biomedicine and health in general. This may involve communication amongst and between medical facilities and professionals, retrieving current information regarding treatment methods for certain disorders, and even helping medical professionals diagnose a disease. It may also involve the sharing of patient information amongst specialists in order to give the patient the best treatment possible.

With the use of computers in the medical system becoming increasingly common, the United States congress passed the Health Insurance Portability and Accountability Act (HIPPAA) in 1006. This act set forth certain regulations and guidelines regarding keeping track of medical records with specialized software. The primary goal of the act was to maintain patient privacy while still allowing medical professionals to take advantage of the conveniences technology provides.

Since then, the Certification Commission for Healthcare Information Technology (CCHIT) was formed through the United States Department of Health and Human Services. This non-profit organization has developed a set of standards regarding electronic health records and the networks that support them. Those vendors that meet these standards receive certification through the organization. In 2006, the organization certified 22 electronic health record products that have been approved for use.

Computer Information Technology

What is computer information technology? To begin, it’s a good question-and quite frequently asked too. Basically, computer information technology (commonly referred to as “IT” within tech industries and the business world) is a term used to describe the design, creation, and maintenance of complex computer and networked computer systems. Many businesses and professionals use the term to also encompass the wide range of technology that surrounds the computer systems themselves too.

For example, computer information technology is often used to describe:

  • Computer hardware
  • Computer servers
  • Computer networks and networking equipment
  • Computer monitors
  • Software and operating systems
  • Printers
  • Copy machines
  • Fax machines
  • Office phone systems
  • Internet systems
  • Cell phones
  • Many additional types of technology and data management equipment

IT also represents the how all of these systems are used and how they inter-relate to one another at the same time.

In the Workplace: The IT Department

While it is not necessarily a rule, more often than not these days, a business’s IT department will typically manage all of the office’s technology needs, including everything from the procurement of computer and technology equipment to the installation and ongoing maintenance of the systems. In the modern data centered workplace environment we’ve come to expect today, ensuring the computer information technology backbone is operating effectively and efficiently has become absolutely mandatory to running a successful business or workplace operation.

Why Is Computer Information Technology So Important?

IT has become the lifeblood of how business is done. As our world continues to adapt more and more towards an information based society, managing the stream and storage of data and making access to data more and more reliable and easy to use is not just important from a profit standpoint alone-we’ve actually come to totally depend on technology 100% to make business possible.

In this type of environment, ensuring that every small “slice of the pie” operates and performs as it should is essential. Think of it much like setting up a chain of dominoes-if one piece of an organization’s technology system goes down, it is certainly going to have an entire chain of cause and effect throughout the entire organization.

Information technology is so important because it requires thoughtful and knowledgeable planning and development to create sophisticated systems that work seamlessly with each other to produce an end result of transparent functionality that we rely on. It’s almost like one of those things that we’ve just gotten used to-we’ve come to expect it to work flawlessly all of the time, only noticing it when something goes wrong.

This kind of operational transparency is usually the main goal of IT professionals. Making sure that data and technology systems work properly and dependably enables others to perform their duties without a hitch. Qualified IT professionals are always in high demand and generally well compensated for the services they provide.

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.

How Can Computer and Internet

The new century has started with a milestone in the development and technology. With the increased popularity of internet functions, cyber crime and theft have emerged as a new propaganda. Apart from online crimes, the computer technology has enabled criminals to break the law and order force with the help of sophisticated instruments. Thus, there had to be the inclusion of computer and technology in the law and order force. Now, developed countries like UK, USA, Germany, France, China, etc. use the scientific instruments such as CCTV cameras to detect the criminal forces. This has become possible only with the introduction of computers. Computers surround all the spheres of a human’s life.

Virtual reality has been a mile stone in the law enforcement. Virtual reality is like a 4D film in which you feel almost as near to the original scene that has happened. This helps during the case solving in a court where the witness tells the scene of the crime in as much detail as he saw it and it is being projected on the screen to match the original scenario that has happened.

Other important achievement that has been made is ‘on site’. This term explains that the police officers and investigators have different tablet PCs or note books in their squad cars which could detect the people, etc. they have databases and other software through which they could carry the interviews and thoughts of people about the crime and send immediate reports to the head office or any law and enforcement controlling official when the scene of the crime is still fresh. Mobile electronics have also proves to be very use full because they can catalog, transfer or copy the evidence at the crime scene and can be managed and processed immediately after it reaches the head department of police station. Other technology like crime scene detectors are able to copy or identify the finger prints at the moment thus enabling the other officers to move fast in the matter and help the police gain full access to the criminals.

Improved telecommunication have allowed reliable and fast mode of communication between different departments of law and order. There can be sending and receiving of the encrypted messages so that no body except then the actual receiver can read the message. Digital radio frequencies are being used by the police department so that there can be easy communication even during the peak hours or when the signals are jammed because of the crime.

LPRT and DNA technologies have also contributed a great deal to the crime detection. LPRT stands for license plate reader technology. This technology uses OCR (optical character recognition) which captures the images. This gives the opportunity to the police officers to track the cars or other vehicles that were present at the crime scene. The DNA technology combines DNA and computer technology to combat violent crime. The DNA that is collected at the crime scene is tested against the output of DNA given by the computers. This helps in the tracking of the actual criminals.
