10.1 Introduction to Management Information System (MIS)
“An organized combination of people, hardware, software, communication networks, data resources, and policies and procedures that helps an organization to collect, process, store and distribute information for decision-making and control.”
It transforms data into meaningful information that can be used to make better decisions at all levels of management.
Objectives of MIS
· To support management in decision-making at strategic, tactical, and operational levels.
· To improve organizational efficiency and productivity.
· To provide timely and accurate information.
· To integrate data across various departments.
· To automate repetitive tasks like payroll and billing.
Components of MIS
1. Hardware
o Devices like computers, servers, printers, networking devices.
2. Software
o Application programs that help process and analyze data (e.g., ERP software, database systems).
3. Database
o Central repository to store all business data in an organized way.
4. People
o Users (managers, staff, IT professionals) who interact with the system.
5. Procedures
o Instructions and rules followed to operate the system efficiently.
6. Network

10.7 Communication Networks and Client-Server Architecture
1. Communication Networks
A communication network is a system that allows computers and devices to exchange data and share resources.
Types of Communication Networks:
|
Type |
Description |
Example |
|
LAN (Local Area Network) |
Connects devices within a small geographic area (office, building). |
Office network |
|
WAN (Wide Area Network) |
Covers large geographic areas (cities, countries). |
The Internet |
|
MAN (Metropolitan Area Network) |
Network spanning a city or large campus. |
City-wide Wi-Fi network |
|
PAN (Personal Area Network) |
Network for personal devices (phones, tablets). |
Bluetooth connection |
Network Components:
· Nodes: Devices such as computers, printers, servers.
· Transmission Media: Physical or wireless channels like cables, fiber optics, Wi-Fi.
· Switches and Routers: Devices to route and manage data traffic.
· Protocols: Rules for communication (e.g., TCP/IP, HTTP).
Importance of Communication Networks:
· Enables resource sharing (files, printers, internet).
· Facilitates communication via email, chat, video calls.
· Supports distributed applications and cloud computing.
· Essential for business operations and global connectivity.
2. Client-Server Architecture
Client-server architecture is a network design model that divides tasks or workloads between servers and clients.
Components:
· Client:
o The user device or application that requests services or resources.
o Examples: Web browsers, email clients.
· Server:
o A powerful computer that provides services or resources to clients.
o Examples: Web server, database server, file server.
How it Works:
1. The client sends a request to the server (e.g., request for a web page).
2. The server processes the request.
3. The server sends back the response (e.g., web page data).
4. The client displays or uses the data.
Types of Client-Server Models:
|
Model |
Description |
|
Two-tier Architecture |
Client directly communicates with the server. |
|
Three-tier Architecture |
Adds a middle layer (application server) between client and server for processing. |
Advantages of Client-Server Architecture:
· Centralized management and control of data and resources.
· Easier maintenance and upgrades.
· Scalability: Can add more clients or servers.
· Supports multiple clients simultaneously.
· Better security as data is stored centrally.
Examples of Client-Server Applications:
· Web applications (browser = client, web server = server).
· Email systems.
· Online banking systems.
· File sharing networks.
