... as I will never stop growing. I have introduced myself to all topics of word processing to surfing the web. After reviewing a number of resources, I have noticed a relatively high demand for technologically integrated hardware and software positions available with companies that wish to compete with the demand for “networking”. (“Computer Scientists” 95) This leads me to believe that future employment prospects will be high and of high quality pay within the next eight to ten years. The past, present, and future have and will see the computer. Since I have seen the computer, I have enjoyed the challenges and countless opportunities to gain in life from this ...

... to a larger number of users and a larger variety of users. (Linux.com) Linux has a powerful security system. It is almost impossible to write a virus for Linux because it must be 30-40 MB. Also, it has firewall system to protect the network from hackers. This minimizes the number of viruses capable of affecting a Linux system. If we think about it, there are many viruses for Windows that can harm your system. Linux is a stable Operating System. You can kill an individual process that is not replying with kill command vs. shutting down your system in Windows. Linux has true multitasking properties. You can run up to twelve processes at the same time with no ...

... science overlapped considerably during this time with the branch of mathematics known as numerical analysis, which examines the accuracy and precision of calculations. As the use of computers expanded between the 1950s and the 1970s, the focus of computer science broadened to include simplifying the use of computers through programming languages—artificial languages used to program computers, and operating systems—computer programs that provide a useful interface between a computer and a user. During this time, computer scientists were also experimenting with new applications and computer designs, creating the first computer networks, and exploring re ...

... memory and file usage. A qualified system administrator should be able to tell by the amounts of memory being used and the file usage if something is going on that should not be. If a virus is found, system administrators can pinpoint the user who put the virus into the network and investigate whether or not there was any malice intended. One computer application that is becoming more widely used and, therefore, more widely abused, is the use of electronic mail or email. In the present day, illegal hackers can read email going through a server fairly easily. Email consists of not only personal transactions, but business and financial transactions. There ...

... is generally interchangeable with Ethernet II, with the greatest difference being the construction of the network packet header. This method consists of multiple workstation that accesses a transmission medium called Multiple Access. Here the medium listen until no signals are detected. This is known as Carrier Sense. After checking to see if more than one signal is present they transmit. This is called Collision Detection. When a collision occurs the station then has to retransmit. The most important part of CSMA/CD access method is collision detection. Workstation may simultaneous transmit causing a collision. A method was needed to prevent this from happening. ...

... and ground states strikes an excited atom, the atom is stimulated, as it falls back to a lower energy state, to emit a second photon of the same frequency, in phase with and in the same direction as the bombarding photon. This process is called stimulated emission. The bombarding photon of the emitted photon may then strike other excited atoms, stimulating further emission of photons, all of the same frequency and phase. This process produces a sudden burst of coherent radiation as all the atoms discharge in a rapid chain reaction. The light beam produces is usually pencil thin and maintains its size and direction over very long distances. Lasers vary greatly in ...

... a fire -- few people realise how large a proportion of businesses fail to re-open after a major fire. I would equate the failure of a Web host for an e-commerce site to that of a fire for a traditional store, and would expect that a similarly high proportion of Web stores would go out of business as a result. I guess that most Web merchants are complacent, either assuming that they will never have to change hosts or that if they do it will be a straightforward matter. However, the truth is that changing your Web hosting service can be very difficult, particularly for e-commerce sites because the software the store runs on - whether CGI scripts or a fully-fledge ...

... waste of time. And the vast information stored here is useless, as if it wasn't there. Secondly, to get anything interesting or informative from the web, no matter what the subject, one must know its exact location, else one is compelled to dive into a muddy flood of shit. This leads me to the point of clarifying the term "information": This word usually has two meanings, a fact that contributes to misunderstandings. It can mean a piece of wanted, useful and understandable data or it can also mean any piece of data. When a stupid chick posts some info that her doggie just pissed on the carpet and she includes on the web page a picture of her with the dog, I ...

... hacker tries to bypass this anyway he knows how to and tries to gain access to the system. Why do they do it, well lets go to a book and see "Avid young computer hackers in their preteens and teens are frequently involved in computer crimes that take the form of trespassing, invasion of privacy, or vandalism. Quite often they are mearly out for a fun and games evening, and they get entangled in the illegal use of their machines without realizing the full import of what they are doing" , I have a hard time believing that so lets see what a "hacker" has to say about what he does "Just as they were enthraled with their pursuit of information, so are we. The thrill of ...

... the researchers who are trying to create very real applications for medical, space, physical, chemical, and entertainment uses among other things. In order to create this alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory display to give depth to sound, sensor lined gloves to simulate tactile feedback, and head-trackers to follow the orientation of the head. Since the technology is fairly young, these interfaces ...
