Introduction
- Computer competency refers to acquiring computer-related skills-indispensable tools.They include how to effectively use popular application packages and the Internet.
- Fives parts of an information system :
1) People
2) Procedures
3) Software
4) Hardware
5) Data
- Computer competency is important because :
1. Microcomputers are common tools in all areas of life.
2. New forms of learning have developed. (e.g. Web learning, Wed courses )
3. New ways to communicate, find people with similar interest, and buy goods are available.
(e.g. e-Bay, Facebook )
INFORMATION SYSTEMS
- A system is a set of interrelated parts( there are 5 of them) that work together to enable people to accomplish tasks more effectively by providing access to data.” (Beekman, Quinn, 2008, pg. 432). Examples, an e-mailing system (vs. snail mail), an e-learning UTM.
1.) People
- An essential part of the system.
- The purpose of imformation systems is to make people, or end users like you, more productive.
- Contact with IS :
a. Directly (Obvious; using Microsoft Word)
b. Indirectly (on-line listening to music, medical scans)
- Computers are used in Business, Entertainment, Education & Medicine.
- Features that help you become computer competent and knowledgeable :
a. Making IT work for you ( interesting and practical applications )
b. Tips (variety of suggestions)
c. Careers in IT ( job descriptions,employment demands, educational requirements,e.g )
d. Computing essentials web site ( integrates the textbook with information on the Web )
2.) Procedures
- Rules or guidelines for people to follow when using software, hardware, and data.
- Example : To access the UTM e-learning system,you need to key-in your name and password,click on the file icon to download files
3.) Software
- A program consists of the step-by-step instructions that tell the computer how to do its work.
- Another name for programs.
- Convert data (unprocessed facts) into information (processed facts)
- 2 major kinds of software : i.) System software (not a single program but a collection of
program, consists operating systems, utilities, and device drivers)
ii.) Application software(end-user software,consists 2 major
categories which are Basic Application and Specialized Applications )
4.) Hardware
- Consists of electronic devices that can follow instructions, accept input, process, and produce
information.
- Types of computers :
i. Supercomputer (e.g. earthquake simulation )
ii. Mainframe computers (e.g. insurance company)
iii. Minicomputers (midrange, e.g. production department)
iv. Microcomputer (least powerful, most widely used, e.g. desktop, notebook or laptop, tablet
PC, handheld )
- There are 4 categories of hardware devices :
i.) System unit (electronic circuitry, e.g. microprocessor,RAM)
ii.) Input/Output devices (e.g. keyboard,monitors)
iii.) Secondary storage ( e.g. hard disks, flash memory cards )
iv.) Communication devices (e.g. modem )
5.) Data
- Raw, unprocessed fact
- Processed data becomes information
- Stored electronically in files : Document
Worksheet
Database
Presentation
Connectivity and The Internet
- Sharing of information
- Wireless communication has widespread use
- Computer networks connected communication system of computers
- Largest network in the internet
