The Future of communication.
The Future of communication -"Behind every man now alive stand thirty ghosts, for that is the ratio by which the dead outnumber the living. Since the dawn of time, roughly a hundred billion human beings have walked the planet Earth. --Now this is an interesting number, for by a curious coincidence there are approximately a hundred billion stars in our local universe, the Milky Way. So for every man who has ever lived, in this universe, there shines a star." (from Clarke's foreword in 2001, A Space Odyssey, 1968) I think the next century; the educational revolution will ensure that learning will be completely liberated from the tyrannies of schedules and locations. Anybody, anywhere will be able to study any subject, and access any form of information - at his or her most comfortable speed. This will make education the life-long process it must be.*** I defiantly think the future of communications is in people. People will become more open to discussion or chat. Interaction of any kind is an important form learning, even body language; people will be more expressive and affectionate with each other. Who knows? The world may be a safer and ever more comfortable place to live…. I mean, we have seen single-interest groups - pro-choice, environmental, animal rights, and gay rights groups being the most prominent in the past centuary. Although I am always feeling since
Unit 21: Working with ICT Hardware and Equipment
Unit 21: Working with ICT Hardware and Equipment The working Process Building a pc for a school When building a pc for a school I need to ensure that it is built to the requirements. As the pc go out to the schools and the connexions centre they need to have specific software etc on the computers for them to run correctly without any problems. When building a pc for a school I need to check the following: Customer Requirements Customer requirements can be from what they need i.e.: * The basic - computer * Which software they are requiring in this case Citrix as the main programme. (Citrix is used to remotely connect to the server from over the internet). * It could also need a certain amount of memory in the computer * A better machine so that it does not cause them the hassle that the old one did. This can be helpful especially if the customer is on their computer all through the working day. Personal advisers that are in schools also need to have computers that can be as fast as required as they tend to hold a lot of interviews with the pupils at the school. * Any extra ram or drivers that are needed need to be placed into the computer carefully. As the ICT team are regularly asked to make sure that computer speed is kept at its maximum for all computers in the business it is important that extra ram is put in carefully, ensuring that health and safety rules are
Solving and Reducing Internet Problems
(M1) Solving and Reducing Internet Problems (M1) Introduction: This report was produced by undertaking research into the ways of solving and reducing some of the problems associated with different types of business activities. I have identified the problems and what solutions would be. The report was produced by Haroon Sheikh and requested by Websters Supermarket. The report was compiled and submitted on 25th FBY 2008. Findings: I have found that less than one-third of Internet users have any idea what phishing is, and less than four percent have changed their online habits, despite most users being the target of numerous phishing scam attacks. Phishing scams are criminal attempts to steal users' personal information by masquerading as a trustworthy business, such as a bank or auction site, in emails or other electronic communications. Any personal data captured is used for identity theft, credit card fraud, and other crimes. Risks of Internet Connection A business with only physical premises to look after still needs to consider security, a business that presents it self on the Internet immediately has many other forms of threats. There are some issues that can affect e-commerce businesses at any time and these must be considered and monitored. These include: Spam - Not-required rubbish or junk mails, which can be blocked through easily installed filters on email
Communications Technology - Assignment 1
Communication Devices - P1 Here I will explain three different communication devices that can be used for worldwide communication. The three that I am going to explain are modems, satellites and mobile phones. Modems (modulator-demodulator) - modems are used to allow computers to communicate with each other over long distances via telephone lines. Essentially their job is to convert a digital signal into an analogue signal and vice versa. This basically means that they convert the digital data (or binary) into modulated electrical signals in the voice frequency of a telephone line. A modem on the receiving end then demodulates these electrical signals into digital data. A section of a telephone line is designated for the use of a broadband connection whilst the other part remains available for voice calls. These are technically the "bands" of a phone line; this is where broadband gets its name from. Broadband filters that are used separate these two bands so that they do not interfere with each other. Modems are generally classified by the amount of data they can send in a given amount of time; usually measured in bits per second. Satellites - satellites are used to transmit a signal from one place to another. They are used to broadcast data all over the world. A satellite can send a signal from somewhere on Earth to a communications satellite in space which then
control questions
I will be looking at different search engines in order to find the information that I am looking for. The information that I am going to be researching is house price data. I'm going to compare 3 search engines to see which one is most appropriate in what I'm looking for. Text based search engine: For this section I'm going to use Google as the text based search engine. In my personal experience many people use Google as their primary search engine. I'm going to search house price data in Google's search bar and see what results I get back from it. The index returned 125,000,000 hits relating to my topic. Directory search engine: For the directory search, I will be using the live search to see what results I get from the topic that I am researching. The results from the search came back with 67,200,000 hits relating to my topic. Meta search engine: For this section I'm going to use ask.com search engine. Ask.com is a little different from the other two search engines because it allows you to actually type a question in e.g. 'how do you build a website' this will return a list of reference related to building a website which I feel is good. I'm going to research the same topic as I did in the other two search engines and see what results I get. The result from this search engine is that I received 4,477,000 hits relating to house price data. Comparing my results
An explanation to the benefits of computer conferencing and collaborative technologies
An explanation to the benefits of computer conferencing and collaborative technologies Contents Page Executive summary 1 Terms of reference 1 Methodology 1 Findings 2 Conclusions 4 References 4 Executive Summary There are various benefits to computer conferencing however there are still a few problems. The best way to eliminate most of these problems is to diversify the ways of communication. Terms of Reference Report From Chris Kiarie Report to Amanda Walker Due Date 26-11-2004 Topic An explanation to the benefits of computer conferencing and collaborative technologies Methodology Well I used the search engine yahoo I typed in "what is computer conferencing" then looked through all the websites available. However the subject matter was too broad so went to advanced search and excluded the word equipment because I was getting too many websites offering the equipment. The evidence for this is on the references it's the yahoo website. Findings Firstly I would like to explain what computer conferencing does. It is the gives the opportunity for interactive group communication, learning and decision-making. This is done by the use of software and either the Internet or a network. The key features of computer conferencing are; * Asynchronous Communication - This means that communication is not affected by geographical location
Database Analysis & Design
Assignment 1 Introduction Within this report I will explain the following areas in detail, * Explain the different types of databases - flat file, hierarchical and relational. Compare the advantages and disadvantages of each. * Describe two analysis methodologies and again compare the advantages and disadvantages. This time use examples to illustrate your key points. * Describe the concepts involved in Logical Data Modelling. * Identify and describe potential modelling constraints that could arise from a logical data model using examples. * Finally discuss the benefits of Logical Data Modelling. Databases There are many different types of databases available for use; the three most common ones are, * Flat file database * Relational database * Hierarchical database I will now explain each database listing the advantages and disadvantages of each. Flat File Databases This section will show a description about flat file databases and the advantages and disadvantages Description A Flat File Database is a text file commonly only containing a record for each line in the file. This sort of database would be used for a simple phonebook sort database, showing peoples names with there telephone numbers and possibly addresses. This could also be used to keep track of friends. An example of a flat file database is a personal phonebook storing names and telephone
Under what conditions would it be appropriate to use a process costing system?
Strayer University Graduate Chapter Questions: Ch. . Under what conditions would it be appropriate to use a process costing system? Process costing system can be used in industries that produce essentially homogenous products on a continuous basis, such as bricks and paper. 2. In what ways are job-order and process costing similar? Job-order and process costing are similar in three ways that the book declares. One, both systems have the same basic purposes- to assign materials, labor, and overhead to products and to provide a mechanism for computing unit product costs. Second, both systems use the same basic manufacturing accounts, including Manufacturing Overhead, Raw Materials, Work In Process, and Finished Goods. Third, the flow of costs through the manufacturing accounts is basically the same in both systems. 3. Costing are accumulated by job-order costing system; how are cost accumulated in a process costing system? Under process costing, costs are accumulated by department, rather than by order, and assign these costs uniformly to all units that pass through the department during a period. 4. What two essential features characterize any processing department in a process costing system? The first feature is the activity performed in the processing department must be performed uniformly on all units passing through it. The second feature is the output of the
Regenerative Braking
REGENERATIVE BRAKING Abstract The purpose of this report is to analyse a recent development in Braking Systems - Regenerative Braking. The report discusses the processes and ideas involved behind regenerative braking, as well as detailing its advantages and uses in modern vehicles (e.g. the Honda Insight). Introduction As the natural fuel sources of the Earth continue to be depleted, new methods of technology and innovations are being investigated to allow engineers to design more efficient methods of transportation. The result has been cars like the Honda Insight, which uses advanced mechanisms to provide fuel efficiency. In modern cities, a typical car in city traffic wastes a lot of energy each time it brakes. In effect, the energy of the forward momentum is lost in the form of heat in the car's brakes. More energy is then needed to reaccelerate the vehicle back to its previous speed. However, recent developments of braking systems have led to a much more efficient and resourceful mechanism of braking - regenerative braking. The idea behind regenerative braking is to recapture some of the energy that would otherwise be wasted during braking. This energy is stored in batteries, so that the energy can later be used on reacceleration. This idea is widely used in both pure electric and hybrid electric vehicles. How it works The Honda Insight uses regenerative braking to
Assess the view that the most important feature of an electoral system is proportionality.
Assess the view that the most important feature of an electoral system is proportionality. Many people citizen many of the electoral systems are that they try to produce a single winner therefore distorting proportionality and the distribution of preferences among the voters. These systems are designed to produce a balance between the total number of votes and the total number of seats which it receives from the legislation. Proportionality is basically about fairness but elections are not always fair, for example, In 1997 Labour only won 44% or the votes but won 64% of the seats using the first past the post system. In a truly proportional system the labour party would only have been entitled to 44% of the seats. Proportional representation tries to prevent this distortion between votes and seats, although it is not always successful. This is the most proportional system where votes are equal to the seats. There are many various forms of P.R, and the most commonly used one is called the P.R List system. This is used in all European countries except for the UK Ireland and France. Parties list there candidates in the order in which they want them to be elected. There are 2 variants of the list system, Closed List and Open List. In the closed list system is used in Israel and Spain. This system can be used in multi-member constituencies, but in Israel there is one
