Chapter 1- Mastery Test

This is the continuation of the Mastery Test, Qu's 1-21 are written in my book.
Questions:
22. Identify the information technology and participants in a computerized library catologue/circulation information system.
- Information technology: Computer System ( which is a database of all the users who have borrowed a book) , modem,software application related to a library catologue system ( one that enables the user to search for books by its title, keywords, author etc.... and lets user know if its in in or out, where to find it, which section etc....)
- Participants:Librarian, School students, University students, teachers, children, anyone....

23. New developments in technology have influenced information systems by:
* Examples of the recent developments are:
- faster systems with more storage allows users to perform complex and difficult processing tasks.
- low cost, high quality digital imaging technology enable users to edit their own photographs and videos in the comfort of their own home.
- better optical storage technologies ( CD-RW and DVD):
CD-RW- enables a user to store and carry around their files.
DVD- enables users to experience a whole new level of watching movies in their own living room.
- the opening of the Internet to home users.
It has created a revolution in many information systems. Internet Banking, online shopping, access to information services, email, online chatting, video chatting ( through the invention of the web cam) etc.... has indeed changed the way people do things.
- Computer based information systems have introduced a whole new array of words, which we use quite often in our day to day lives, such as : "CD- ROM" , "email", "download" and it has given other words new meanings, " surfing the internet".
The development of technology has also led to higher expectations of information systems, such as:
- "demanding faster internet connection with more multimedia services"
- as computer can display video images, users expect video to be a "normal part" of computer information services, ( Internet).

24. Computer- based information technology has altered the roles of participants in information systems by:
As people are not only there to serve the technology but are also involved at all levels of an information system. In saying this, there are those who supply data to an information system, those who manage the data in the system ( E.G. data entry operator, web designer) and those who use the information the system provides.
Furthermore, there are those who simply receives the data/information produced by an information system, who are called end users. They are not specifically participants but simply those who use any of the technology in an information system to obtain information they need.

25. Computer- based information systems have become a vital part of our lifestyles as now everything is literally performed on the internet and on the computer. Writing letters to others on the other side of the country have been put aside by few, as emailing came into the picture. People are able to communicate online through MSN, Yahoo and are even able to video chat. As well as that, as some have had a tired day at work and have no time to go shopping, its just a simple click away, as online shopping at popular supermarkets such as Coles, Woolworths are common nowadays. Furthermore, people are able to view newspaper articles online, find the weather forecast, view TV guides, check out some recipes to cook for dinner, or the latest movie reviews. Of course, for the current generation, books are only a second resource when it comes to an assignment as well as homework, Google is literally just a click away. With the invention of face book and twitter, those few hours twiddling thumbs and maybe reading a book for an hour has disappeared.
Its not only the internet, which have become a vital part of our lives, but Mobile phones is a device nearly everyone has nowadays. This generation will go nowhere without it, its like a new pet, and as for some adults, their work is surrounded with the use of it. As technology has once again developed, such as the Iphone, which lets one watch movies, listen to music, go on the internet, download apps,has a maps, navigation (apps), its changing the way we do things even when going out.
As well as that automatic teller machines [ATM] have also become a vital part of our lives, if we need money all we have to do is get our card out and swipe it, we even get to know how we have in our account. Who would have though that back then, you would have to actually go to a bank teller and ask for money from your account.
As for electronic entertainment such as TV's, portable DVD players, Blu- Ray, DVD Players, PS P's, XBox, Wii, Ipods, its unbelievable to think that they never existed 20 years back or so. You can watch movies in high quality with your surround system, cinemas are just a second resource for those hot days. Its revolutionized the way people spend their time nowadays.
Computer- based systems have definitely become a vital and enormous part of our lifestyle, that it has got to the point of people saying " they cant survive without the the things listed above, that it would be a world of boredom without it".

26.
Personal information systems, are designed for the use of an individual. These systems collect, process, store and display data that are intended for the private use of one person. There is normally only one participant. The end users have total control over a personal information system.
Group information system are designed for a group of people. Many different people will add data and share the information they produce. Group information systems have many participants. The individual users ( end users) have little or no say in how it is used. They "usually" dont control the selection of the data to be entered, how it will be processed and how results will be used. Such decisions are made by an authoritative figure ( E.G. system manager).
