Question 1 There are four main types of printer: a) Laser printers The laser printer is very expensive to buy but cheap-ish to run. The output quality is very high, and it prints very fast. The function of a Laser printer is that it very rapidly produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back & forth over an electron-charged, cylindrical drum, to define a differentially-charged image. Advantages Disadvantages • Colour printing is possible • Print quality is good • Noiseless • Printing speed is high • Most models are relatively light weight and compact so they don't take up too much space on the desk • Not be the printer of choice for everyone, Due to the cost of ink, running …show more content…
Examples of internet threats are image spamming, phishing, e-mail borne viruses, e-mail spoofing, chat clients, overseas money transfer scam, Trojan Horse programs, Denial of Service Attack (DOS Attack), being an intermediary for another attack, modem hijacking, unprotected windows shares, mobile code (Java/JavaScript/ActiveX), cross-site scripting, hidden file extensions and packet sniffing. b) Internet security is a tree branch of computer security specifically related to the internet, often involving browser security but also network security on a more general level as it applies to other applications or operating systems on a whole. Its objective is to establish rules and measures to use against attacks over the Internet. Examples of internet security are network layer security, Internet Protocol Security (IPsec), security token, electronic mail security (E-mail), Pretty Good Privacy (PGP), Multipurpose Internet Mail Extensions (MIME) and message authentication code. c) Data recovery is the process of salvaging and handling the data through the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
...linsky, Eric. “Using 3-D Printers…” All Tech Considered. Feb 06, 2013. Nov 5, 2013. .
Wood-type printing allowed new typefaces to be created and used for printing cheaper than ever before. Technological advances permitted machine-set typography to be printed on machine-manufactured paper with high-speed steam-powered printing presses. The use of color lithography passed the aesthetic experience of colorful images from the privileged few to the whole of society.
These requirements might seem obvious at first, yet it is exactly the demand and supply on each one of them causes the limitation and control of this technology. The 3D printer is no longer an equipment which only can be found in a scientific lab, but people can buy it on Amazon with the price from 600 to 2000 dollars. Moreover, there are numerous companies which start to invest new functions upon the 3D printer such as the three types of 3D printers that have been advertised in the “Top 3 Best 3D Printers You Must Have” video: “the Tiko, the Palette, and the Moonray” . For instance, the Tiko printer is a new type of “uni-body” 3D printer which prevents the unstable printing problem caused by the traditional “separate three-piece rails frame” . Also, its 1 kg rolls large “internal filler” and the “close-build chamber” also promises the project to be more “reliable and accurate” . What the most considerate for the consumer should be its “wireless connectivity” . This way, any consumer can print anything at anywhere they want as long as they have a downloaded Tiko app on their cellphones or laptops. As for the Palette 3D printer, it wedded to developing the “controllable multi-color functionality” because most of the previous settings of the 3D printers only allow the consumer to print with one color at a time . Therefore, the
Xerox's "Book In Time" is a revolutionary product, presenting some new opportunities for the company. It is simply a matter of costs. The Book-in-Time equipment allows for a publishing company to produce a 300-page book for $6.90, something which could have been previously reached only for lots larger than 1,000 copies. A significant decrease in publishing costs, given the fact that these cover up to 20 % (including the paper and binding the book), would create the possibility of an increased profit margin.
As a multinational, Xerox specializes in technology and services and operates under two different market environments, the macro and microenvironment. In the microenvironment, the company has influence while in the macro-environment the company cannot make market changes.
The printing press is a moveable type machine that is used by transferring text and images to paper using ink. The machine helped change society from making hand written books to producing books more rapidly. The printing press was more effective when it came to text and images being seen on paper. When material had to be hand written it was hard to read, but the printing press made reading a lot easier. The printing press invention became more efficient when wanting to spread work faster. The invention of the printing press was one of the most useful technology in history because it helped spread ideas, produced books, and improved the economy greatly.
While many people don’t realize it, there is always a risk when you use the internet. You must be able to know how to defend yourself against these attacks, or you risk losing it all. References Denholm, Martin. The. The Number One Threat to America's National Security."
In addition to the technical machines, it is necessary to have consumable goods such as ink, toner, and copy paper for printing. Currently, SG has a contract with an electronic company located in Gainesville named B&B, and SG pays them $0.008/ page from the printing fund for proving the necessary toners and printers for current ten printing stations under Student Government [2]. However, SG provides the copy papers, but it is inexpensive. Fifty packets of standard size copy papers (8 ½...
These also are very portable and light-weight in weight a bit like your notebook thus you don't have to worry a lot of about the weight. These stands square measure one in all the most vital accessories that you should give attention to if you actually wish to form your computing
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
Cutting: A laser is also great for cutting objects. It can get to those hard to reach places by the use of mirrors to bend the beam of light. It also is strong enough to cut through solid steel. A laser never damages the surface of the object because it never touches it. Lasers have been
These are the most common types of Cyber Crimes people see on a daily basis. Although the internet is a great source for making money in legal ways, it is also used for plenty of malicious black market money scams. It is imperative to always carefully browse the internet, when downloading programs, and talking to people online. Works Cited "Cyberstalking" Marshall University. Marshall University, n.d. -.
A printer is an output device that produces texts and graphics on a physical medium such as transparency film, posters and various types of paper. Printers are one of the most used peripherals on computers and are usually used to print photos, images, text and store as hard copy. The printed materials and information are the hard copy which is in a permanent and readable form. There are a wide variety of printing devices available due to different needs of people all around the world. Thus, printers are existed with different speeds, functions, prices and printing methods.
