Definition A set of interrelated elements or components that
collect (input), manipulate (process), and disseminate (output) data and information and provide a feedback mechanism to meet an objective

Hardware Computer equipment used to perform
input, processing, and output activities The objects that you can actually touch,
like disks, disk drives, display screens, keyboards, printers, boards, and chips.
![Page 38: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/38.jpg)
Hardware refers to objects that you can actually touch, like disks, disk drives, display screens, keyboards, printers, boards, and chips. In contrast, software is untouchable. Software exists as ideas, concepts, and symbols, but it has no substance.
Books provide a useful analogy. The pages and the ink are the hardware, while the words, sentences, paragraphs, and the overall meaning are the software. A computer without software is like a book full of blank pages -- you need software to make the computer useful just as you need words to make a book meaningful.
![Page 39: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/39.jpg)

Software Computer programs that
govern/determine/control the operation of the computer
Computer instructions or data
![Page 41: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/41.jpg)
Software is computer instructions or data. Anything that can be stored electronically is software. The storage devices and display devices are hardware.
The terms software and hardware are used as both nouns and adjectives. For example, you can say: "The problem lies in the software," meaning that there is a problem with the program or data, not with the computer itself. You can also say: "It's a software problem.“
![Page 42: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/42.jpg)
The distinction between software and hardware is sometimes confusing because they are so integrally linked. Clearly, when you purchase a program, you are buying software. But to buy the software, you need to buy the disk (hardware) on which the software is recorded.
Software is often divided into two categories. Systems software includes the operating system and all the utilities that enable the computer to function. Applications software includes programs that do real work for users. For example, word processors, spreadsheets, and database management systems fall under the category of applications software.
![Page 43: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/43.jpg)

Database An organized collection of facts and
information A collection of information organized in
such a way that a computer program can quickly select desired pieces of data
![Page 45: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/45.jpg)
A database is a collection of information organized in such a way that a computer program can quickly select desired pieces of data.
You can think of a database as an electronic filing system. Traditional databases are organized by fields, records, and files. A field is a single piece of information; a record is one complete set of fields; and a file is a collection of records. For example, a telephone book is analogous to a file. It contains a list of records, each of which consists of three fields: name, address, and telephone number.
![Page 46: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/46.jpg)
An alternative concept in database design is known as Hypertext. In a Hypertext database, any object, whether it be a piece of text, a picture, or a film, can be linked to any other object. Hypertext databases are particularly useful for organizing large amounts of disparate information, but they are not designed for numerical analysis.
To access information from a database, you need a database management system (DBMS). This is a collection of programs that enables you to enter, organize, and select data in a database.

Telecommunications The electronic transmission of signals for
communications; enables organizations to link computer systems into effective networks
Refers to all types of data transmission, from voice to video
![Page 50: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/50.jpg)

Network Used to connect computers and
computer equipment in a building, around the country, across the world, to enable electronic communications
A group of two or more computer systems linked together
![Page 52: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/52.jpg)
There are many types of computer networks, including:
local-area networks (LANs) : The computers are
geographically close together (that is, in the same building).
wide-area networks (WANs) : The computers are farther apart and are connected by telephone lines or radio waves.
![Page 53: 01 intro to mis](https://reader033.vdocuments.mx/reader033/viewer/2022052903/5577801fd8b42a56728b53ea/html5/thumbnails/53.jpg)
In addition to these types, the following characteristics are also used to categorize different types of networks:
topology : The geometric arrangement of a computer system. Common topologies include a bus, star, and ring.
protocol : The protocol defines a common set of rules and signals that computers on the network use to communicate. One of the most popular protocols for LANs is called Ethernet. Another popular LAN protocol for PCs is the IBM token-ring network .
architecture : Networks can be broadly classified as using either a peer-to-peer or client/server architecture.

Computers on a network are sometimes called nodes.
Computers and devices that allocate resources for a network are called servers.

MIS is short for management information system or management information services, and pronounced as separate letters
MIS refers to a class of software that provides managers with tools for organizing and evaluating their department. Typically, MIS systems are written in COBOL and run on mainframes or minicomputers.
Within companies and large organizations, the department responsible for computer systems is sometimes called the MIS department. Other names for MIS include IS (Information Services) and IT (Information Technology).

An expert system is… A computer application that performs a task
that would otherwise be performed by a human expert
gives the computer the ability to make suggestions and to act like an expert in a particular field
Examples: diagnose human illnesses, make financial forecasts, schedule routes for delivery vehicles
Expert systems typically include “artificial intelligence” (next slide)

AI is… A branch of computer science concerned
with making computers behave like humans
Term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology
Draws from many areas, including cognitive psychology

Artificial intelligence includes games playing: programming computers to play games such as chess and checkers
expert systems : programming computers to make decisions in real-life situations (for example, some expert systems help doctors diagnose diseases based on symptoms)
natural language : programming computers to understand natural human languagesneural networks : Systems that simulate intelligence by attempting to reproduce the types of physical connections that occur in animal brainsrobotics : programming computers to see and hear and react to other sensory stimuli

Attempted to replace humans in decision making
However did not take into account How humans actually reason Human information needs (doctors do
not want their decision making replaced, but rather want it supported)
