Management Information Systems (Chapter 1) Flashcards
What is Management Information Systems?
Development and use of information systems that help businesses achieve goals and objectives.
What is Moore’s law?
“the number of transistors per square inch on an integrated chip doubles every 18 months”
Therefore, the speed of a computer chip increases in proportion to the density of the transistors.
{Density doubles, Speed doubles}
- In addition price and performance ratio falls. They become smaller and less expensive.
What is an information system?
A group of components that interact to produce information.
What are the components of an information system?
Hardware Software Data Procedures People
Define: Hardware
Give examples.
Input and output systems.
Processors, servers, networks, computers, routers, keyboards etc.
Define: Software

Software is the programs used on the hardware. Used to record things like customer details, purchase history, or simple information processing like word or excel.
Define: Data

Define: People
The people that work for an organisation doing tasks.
The ‘checkout chick’ that is scanning your products at the supermarket.
Why management information systems?
Due to Moore’s law the cost of data communications and storage is essentially zero.
Therefore business professionals need to be able to assess, evaluate and apply emerging information technology to businesses.
Do business professionals need to be involved in Information Systems?
Yes.
- Take an active role to ensure the system meets their needs.
- Consider how IT systems are constructed.
- Consider the user’s needs in development
- Learn how to properly employ them
- Take into account any other functions like security and backup used in IT.
How does Management information systems (MIS) help achieve organisational goals?
- People do not do anything on their own
- MIS empowers business people by helping them achieve their goals and objectives through the functions it provides.
How does IS differ from IT?
IT = Hardware + Software + Data (raw technology)
IS = IT + procedures + people
IS groups things together to make a system, which can achieve more together than its separate parts.
What is our role in IS security in terms of passwords?
- Never give it out
- Never write it down
- Do not share it
- If someone needs your password, go over to their machine and type it yourself
- Stay present while your password is in use
- Ensure that your account is logged out at the end of activity
Strong passwords have…
- Seven characters or more
- Do not use any name associated with you or the company (last name, first name etc. )
- Do not use a complete dictionary word
- Use upper and lower case letters, numbers and symbols.
