The computer was not originally invented for the things we use it for today but out of the need to solve a number-crunching crisis. By 1880 the
U.S population had grown so large that it took over seven years to tabulate the U.S census results. In a search for a faster way to get the job done, a punch card system was developed by Herman Hollerith which calculated the
U.S census in three years. Earlier computers were not compatible for the many functions they are performing today. Over the years there have been many improvements in the functions of computers thus making it the most helpful tool of technology.
In the workplace computers are used for communication. Prior to computers, workplaces had multiple receptionists answering the phones and redirecting calls. With new technology, computerized phone systems answer phone calls and direct callers to the exact extension they want with the push of a few buttons. Email is another form of communication that workplaces use it is the preferred method of communication for some workplaces because it is immediate, it’s not as disruptive as phone, calls and the recipient can finish their task at hand before by sending an email. Instead of having towering filing cabinets, computers are able to store data therefore utilizing less office space. Many companies keep their client records in databases for quick retrieval and review.
Many criminal investigation units utilize computers in their process to investigate crime. Investigators integrate the fields of computer science and law to investigate and solve crime. Computer forensics has been indispensable in the conviction of well-known criminals such as terrorists, sexual predators, and murderers. Investigators use computers to recover evidence from GPS to track the whereabouts of suspects, an example of this is when the U.S forces found the Pakistani compound where Osama Bin Laden was killed by

tracking satellite phone calls made by his bodyguard back in 2011.
Investigators check suspects computer for more evidence. Files are not deleted permanently from the hard drive of the computer so the investigators are able to find the files. Criminals use encryption software to encrypt their files to make it harder for the investigators to find them but the criminals often times encrypt a ton of their files making it possible for investigators to find the evidence.
Another area where computers are useful is in animation. An animator's job is to bring a static image or object to life by giving it movement and personality. This job is not possible without the two basic kinds of animation, computer-assisted and computer-generated.
Computer-assisted animation is two-dimensional like cartoons. The animator draws objects and characters either by hand or with a computer. He then positions his creations in key frames, which form an outline of the most important movements. Next, the computer uses mathematical algorithms to fill in the frames. This can be done by hand, but are accomplished much faster with a computer. Computer-generated animation is three-dimensional meaning that objects and characters are modeled on a plane with an X, Y and Z axis. This can't be done with pencil and paper. Computers are used to make these characters break physical laws like gravity, mass and force.
The learning environment has been changed by computers a lot since the past.
Internet access allows students to conduct comprehensive research and communicate
Wommack 08/28/2013 Computers: Past, Present and Future Personal computers have been around for quite some time now, but it might come to surprise that the first personal computer wasn’t invented til 1981. Although, it depends on what you would consider a “computer,” some have been around since the early 1900’s. In 1613, the word computer became coined to a person that could perform calculations or computations. The term remained the same until about the late 1900’s. The first computers were only used…

“DEPENDENCE ON COMPUTERS” Everyday for a month when I came home, I went straight to my computer, to play games and checked my email. Before I done anything else. So I was depending on my computer to be up and running. I stared asking myself a question,”Is dependence on computers a good thing or should we work to be more disbelieving of its benefits?” I found this to be an interesting question I had to answer for myself. to the way in which I am researching the positive and…
not necessary to try and identify how many devices you'll need. Assume that you are recommending five PCs that are all equipped the same. There are some possible exceptions to this approach. You might have a device that is shared between the five computers (scanner/printer, maybe?) and in that case you should say so. You need to specify how a particular item ties back to a specific requirement. You are presenting to the CIO who will want to see details.Is the monitor large enough to accomodate…
Since the birth of computers in 1939, Information technology systems and managing information has become the driving force behind many of the advances the society has gone through over the past 70 years. In today’s world, information technology (IT) has touch just about every part of our lives. The impact technology has had upon society today cannot be measured. In fact, it has had such an impact that if it were wiped out then the human race would be thrown back into the ‘Dark Ages’. Technology has…

Review 1. Packets- a packet is a small piece of data (one unit of binary data) sent over a computer network. Packet formats generally include a header, the body containing the message data (also known as the payload), and sometimes a footer (also known as the trailer). The packet header lists the destination of the packet (in IP packets, the destination IP address) and often indicates the length of the message data. The packet footer contains data that signifies the end of the packet, such…

New Computers at Optimeyes Technology seems to be rapidly growing every day and without the proper technology, some businesses may fall by the wayside. Currently, at Henry Ford Optimeyes we have computers that date back to the year 2004, which means we are using technology from 10 years ago! There is never a better time than the present to upgrade our computers systems so that we will have the tools we need to not only help patients faster, but also have the basic tools we need to do our jobs in…
