ICT applications

• communication applications include: newsletters, flyers and posters, applications used for publicity and corporate image publications, websites, multimedia presentations, cartoons, music scores, mobile phones and text messaging.
• when producing a newsletter is important to ensure that the document looks impressive while remaining readable without too many distracting effects.
• DTP (world procesor and/or a desktop publishing) applications allow for many different publishing formats with very little efort.
• Duplex: a feature of printers that enables automatic printing on both sides of a sheet of paper.
• Flyers and posters contain more text than a poster but it is eye-catching and more illustrative than a text-heavy newsletter.
• Examples of publicity and corporate image publications include business cards, letterheads, flyers and brochures, etc...
• A website is a collection of web pages, text, graphics, video and sound.
• A website is hosted on a web server on the internet.
• The information on the website can be viewed by internet users using a web browser.
• Websites are used to raise the profile of either a person or organisation and to communicate with others.
• Multimedia presentations use a mixture of different media to present information effectively and to maintain the interest of the viewer.
• Computer assisted learning (CAL) presentations are interactive and give the opportunity to manage your own learning.
• CGI: Computer-generated imagery software for creating cartoons.
• Music is written by a composer who then writes it on a 'staff' or 'stave', which is a series of parallel horizontal lines.
• MIDI interface translates the signals from the attached instrument into electronic data.
• 3G and 4G: communication protocols used by smartphones to connect to the internet, 4G being much faster that 3G.
• Text messaging is the least expensive way of communicating using mobile phones.
• using SMS (short messaging system) is usefull as it makes it quick and simple to send short messages.
• The Voice Over Internet Protocol (VOIP) allows the use of internet to carry voice data when making phone calls.
• Data handling applications include: surveys, address lists, club and society records, school reports, school libraries, etc..
• Data traking, data mining and data analysis are some of the most important tasks that most organizations are required to do.
• Data analytics (DA) is a relatively new science that analyses a large amounts of raw data so that conclusions can be made which can influence decision making more accurrately.
• Thee starting point whatever the data-handling application is data collection.
• Data collection can be done automatically but an other method are the surveys.
• Surveys are condoucted using data capture forms.
• Data capture forms can be done on paper, electronically and filled directly into the computer.
• Address lists or contact details are vey valuable due that organizations that deal with mail orders need to be able to send brochures to potential customers, so a list of names and addresses is something that can be used for their bussiness
• Club and societies need to keep data on their members. this data can be searched for specific members of the club so that they can be contacted.
• school reports include information such as: student specific data, student progress, absences and late arrival, teacher comments, date of the report.
• The school libraries handling applications will need to keep track of the students who can use the library and the books that they can borrow.
• The main thing that computers need to be used for in libraries is to keep a check on which books are out on loan and who has them.
• school libraries need 3 files , school library students file, school library books file and school library loans file.
• ISBN: International Standard Book Number, which consits of 13 digits, ISBNs include a check digit calculated using a mathematical formula to validate the number.
• A meashurment application has something to do with measuring a value or a set of values.
• sensors will measure analogue data will must be changed to digital data to be used by a computer system.
• ICT is better than a human providing great precision and taking measurements.
• An automatic weather station typically consists of a rechargeable battery, a data logger, and various sensors.
• The reasons for using ICT in meashurment are precision, reliability, accuracy, non-interference, computer- recorded data can be analysed more easily and quicky than a human-recorded data, and automated systems can operate where humans cannot.
• Many scientific experiments need to be controlled by processors which can take measurements and decisions based on the measurements they have taken.
• The use of sensor to take measurements during scientific experiments is important because sensor can be used where human beings cannot, findings are based on the accuracy of the measurements that are taken, there is a need for the measurements not to be missed and it is important to ensure that nothing interfered with the experiment that may change the results.
