System and Upgrades
MAINTAINING SYSTEMS & UPGRADES TASK 1(A) - RANGE OF UTILITY SOFTWARE Utility software are computer programs designed to manage and tune up the computer OS and hardware. They prevent or reduce problems by diagnosing and correcting the faults before it gets worse. Some of the main utility programs are described below: Disk De-Fragmenter A de-fragmenter scans for fragmented computer files and move them together to increase efficiency. It reduces the amount of fragmented files in a computer system. It tidies up the hard-drive reusing the space more efficiently after a disk cleanup. Defragmentation's result will be the best if it's carried out after a disk cleanup, as all the unwanted files will be deleted. The application can be loaded from the control panel or from All programs/Accessories/System Utilities from the Start Menu. Clicking on the Analyse button on the application window shows the estimated disk usage after defragmentation. We can then choose to defragment the disk by clicking on the Defragment button. Screen shots of the defragmentation process are displayed below: The screen shot above shows the result of the process. Antivirus Antivirus software prevents and removes Viruses, Worms and Trojans from the computer. Most of the antivirus software comes with built in spyware, adware and malware removal tools. Antivirus software uses different methods to
The History of The Cell Phone
The History of The Cell Phone Long ago, smoke signals and tribal drums were used to communicate over short distances. There were no cords. No wires. You were free to send those smoke signals wherever you wanted. But, as time passed, people grew tired of those long, cloudy conversations and teenagers who drummed all night. They started sending messages on horse and rider. And eventually, through wires. People like Claude Chappe, who invented the telegraph in 1792, and Alexander Graham Bell, who first sent voice transmissions in 1876, made communication easier with the use of wires. Needless to say, the Pony Express went to the glue factory. And people started running to their phones every time they rang. It wasn't until 1894, outside of Bologna, Italy, that wireless communication got back on track. Late one night, 20-year-old Gulielmo Marconi woke his mother to show her another one of his crazy inventions. He tapped out a message in Morse Code. And in response to the signal, a bell rang on the other end of the room. Because the signal traveled through the air, Marconi called it 'Wireless'. So, since Bell's telephone wires could carry the human voice, naturally scientists began to search for ways Macron's Wireless could broadcast speech too. And in 1906, Reginald Fessenden did it by changing sound waves into signals through a process called amplitude modulation, or AM for
Unit 3 - Impact on Information Availability
Task One - Impact on Information Availability What electronic information do I access and what impact has this had on my life The internet has had a huge impact on people's lives throughout the world, it allows people from all over the world to communicate and meet in one place, and the impact is clearly visible in today's society. Originally used for communication and business the internet has quickly grown and everything can now be found on the internet quickly and easily. Personally, the internet plays a big part in my life as it is easy to find any information that I may require. It assists me in my school work and revision with sites like BBC Bitesize set up with revision resources and links to other helpful sites. I also use the internet for the latest news (and weather) using sites such as BBC News which contain all the days main headlines as well as discussion by the public on these stories. More recently I have been using the internet for online shopping, which is particularly helpful for events such as Christmas, with sites like Amazon and Play supplying goods for cheaper prices than most high street retailers as well as quick and efficient delivery. All of these websites listed are everyday sites which I use as helpful aids in my life, but I also use the internet for my interests and hobbies. I frequently visit sites such as Skysports to check all the latest
Assignment 2 Set up a Computer System
Task 1 Virus Protection In today's technology there are load of viruses that are harmful to any computer systems, however as the years go on they are to me becoming a thing of the past because we are more protected and most of us know what to do when we are attacked. I am not saying that no to worry but not to fear as long as we are protected and we are constantly backing up we will be fine. Types of virus There are loads of viruses out; here is a list of most common Trojan horse A Trojan horse virus is common, but yet difficult to remove, as it tricks people by hiding it's self in an application. The role of the Trojan horse is to allow other virus in by making a gateway to target computer systems. Spy ware Spy ware is a type of malware that is installed on computers and that collects information about users without their knowledge. Spy ware programs can collect various types of personal information, such as Internet surfing habits and sites that have been visited. Spy ware interferes with the control of the computer in other ways. An example of this would be installing additional software and redirecting Web browser activity and personal information like bank details, passwords. Worm Computer worms are one of the most common viruses, the worm is quite cleaver as it makes copies of itself. Unlike many other viruses the worm does not need to attach it's self to
Artificial Intelligence.
Define what is meant by the term Artificial Intelligence Artificial intelligence is a branch of computer science that deals with the creation of computer programs that can provide solutions that otherwise humans would have to solve. On a broader spectrum artificial intelligence attempts to imitate human behavior and intelligence to generate these computer programs. However artificial intelligence is the youngest of studies, and is evolving every day. The ultimate aim of artificial intelligence and its study is to imitate and/or duplicate intelligence of humans in computers and robots. Artificial Intelligence improves productivity, personnel upgrading, new training and to aid in the solving of difficult problems. With the aid of a suitable diagram, illustrate the branches of A.I and define where Expert Systems reside within it. [http://distancelearning.ksi.edu/demo/509/ch01a.html] The diagram above illustrates the seven (7) areas that Artificial Intelligence is comprised of. Of course with the speed of progression of such a complex study such as Artificial Intelligence these areas are rapidly growing however they are more commonly defined in to one of these seven 'branches'. "AI has many areas of interest. The area of expert systems is a very successful approximate solution to the classic AI problem of programming intelligence."
High-context vs. Low-context Culture
With the quick development of globalization, different countries in the world become increasingly related to each other in many fields including culture. Nowadays people have more chances to communicate with other people coming from different countries thus intercultural communication has been quite frequent and common. With regard to communication, one of the most important components is context and cultures can be divided into high-context cultures and low-context cultures (Hall cited in Singh, Zhao and Hu 2005:135). As Jandt (2004:61) mentioned, when people from high-context cultures and low-context cultures meet, they are very likely to encounter problems since different cultures may affect understandings of communication in different ways. The aim of this essay is to compare high-context cultures with low-context cultures and illustrate how each type of culture react in situations involving language, time, personal space, and interpersonal relationships. It will also examine the problems occurring in the process of communication between these two cultures and try to provide the ways of overcoming the difficulties. Context can be defined as "the environment in which the communication takes places and which helps to define the communication" (Jandt 2004: 33). The theory of high-context and low-context cultures was firstly put forward by Dr. Edward Hall in 1976 (Jandt
ICT Systems in Organisations - Broadoak Community School.
ICT Systems in Organisations - Broadoak Community School This report is going to be based on the ICT system in Broadoak Community School. It will include the main hardware and software components that we use, the networks and connections and an analysis of the hardware, software and the system's efficiency. HARDWARE The physical, touchable, material parts of a computer or other system. The term is used to distinguish these fixed parts of a system from the more changeable software or data components, which it executes, stores, or carries. Computer hardware typically consists chiefly of electronic devices (CPU, memory, display) with some electromechanical parts (keyboard, printer, disk drives, tape drives, loudspeakers) for input, output, and storage, though completely non-electronic (mechanical, electromechanical, hydraulic, biological) computers have also been conceived of and built. [Definition according to Dictionary.com] Hardware can be divided into three categories, Input, Output and Process. Input hardware is defined as an object used to enter information into a computer such as keyboards and scanners. Output hardware is defined as an object used to extract information from a computer such as printers and monitors. Process hardware is the objects that process the information inside the CPU such as processors. The school uses many types of hardware including: ?
According to Weber, what makes bureaucracies efficient? Do you agree?
According to Weber, what makes bureaucracies efficient? Do you agree? Introduction This essay set out to understand what, according to Weber makes bureaucracies efficient. To understand the efficiencies of Weber's bureaucracy, we have to understand why bureaucracies have formed and how they have formed. Furthermore, we have to understand their inherent characteristics which creates efficiencies and how this has caused by rationalisation. I will then look at the different types of rationalisation and understand which type of rationalisation Weber was referring to in the construction of the rational bureaucracy. Their characteristics have then to be analysed and thus understood how these efficiencies work and whilst analysing these characteristics, we have to see if there are any irrationalities or inefficiencies which can arise out of what Weber views as efficient. With this, I will then look at argument against Weber's Ideal Type of bureaucracy, and why some sociologists do not believe that Weber's bureaucracy is efficient. Thus, by looking at both arguments, I would be able to drawn a personal conclusion. Types of Bureaucracy and their Functions Bureaucracies form, according to Weber, primarily because there are pressures by the capitalist market economy which demands that administration either private or public "be discharged precisely, unambiguously, continuously

A Brief History of the Internet Introduction This research report will present a brief history of the Internet, focusing on some of the milestones in the development of such a fundamental international computer network system. In order to convey thorough understanding each milestone will be discussed in significant detail, thus expressing an in depth study allowing one to develop a thorough comprehension of the growth, use and possible future developments of the Internet. When it comes to technology, all we want is more. We want it faster, we want it accessible, and we want it now. It's a trend that has always existed, and will continue existing while there is pressure from the population. Since the creation of the Internet in 1969, the Internet has rapidly developed and nowadays for most the Internet is a crucial tool for daily life. The Internet has changed the way we communicate with others due to social networking sites such as Twitter. The Internet has changed the way we express ourselves with the likes of anonymous video commenting to personal online blogging. The Internet has changed the way we advertise business and sell products through the expansion of e-Commerce. The Internet has changed the way we deliver news with many current political and foreign affairs easily accessible nowadays public outrage is exacerbated, e.g. the US 'murder' of Osama Bin Laden (May
