Study Notes
Business Information Systems
- Computers are essential for storing, managing, and analyzing large amounts of data, leading to "Big Data" analysis in commerce.
- Businesses use computers to understand buying patterns, trends, and consumer preferences.
- Computers are vital tools in every aspect of business operations, including product development, marketing, accounting, and administration.
- Choosing the right computers, software, and peripherals is crucial for businesses.
- Business technology automates back-office functions like record-keeping, accounting, and payroll.
- Secure environments for sensitive business/consumer information are enabled by technology.
- Communication with customers can be improved using technology
Advantages of Computers in Business
- Access to more information sources.
- Increased opportunities for collaboration and networking.
- Easier access to information resources.
- Increased efficiency.
- Increased services.
Computer Components ("HW & SW")
- Desktop Computers: Designed to remain in one location on or under a desk.
- Laptop Computers: Portable personal computers that fit on a lap and are powered by batteries.
Types of Software
- Word Processing Software: Used for creating, editing, printing, and saving documents.
- Multimedia Software: Combines text, audio, images, animations, and video for interactive content.
- Web Browsers: Applications for accessing websites.
- Graphics Software: Used to manipulate images and models visually on a computer.
- Freeware: Software offered for free.
- ERP (Enterprise Resource Planning): Software system streamlining core business processes (finance, HR, manufacturing, supply chain, sales, and procurement) providing a unified view of activity and a single source of truth.
Computer Software Examples
- Operating Systems: (Microsoft Windows, Linux, macOS)
- Productivity Software: (Microsoft Office Suite, Word, Excel, PowerPoint, Internet Browsers; Firefox, Chrome, Safari)
Functions of Operating Systems
- Providing a consistent way for applications to work with the CPU.
- Managing computer hardware.
- Scheduling, coordinating, and managing tasks.
- Managing files (accessing, arranging, saving, deleting).
Computer Hardware
- Motherboard: The main printed circuit board (PCB) acting as the computer's central communication hub.
- CPU (Central Processing Unit): The "brain" of the computer, performing calculations. It's a microprocessor containing millions of transistors.
- ALU (Arithmetic Logic Unit): A digital circuit within the CPU that performs billions of arithmetic and logical operations per second.
- RAM (Random Access Memory): High-speed, short-term memory for the computer's CPU.
- ROM (Read-Only Memory): Stores startup instructions (firmware) for the computer.
- Cash Memory: Specialized memory for frequently accessed information, improving system performance.
Memory Hierarchy
- Arranging storage devices based on size, cost, access speed, and roles within application processing.
- Levels of memory (Level 1, 2, 3 cache; Main memory; Magnetic disk; Optical disk; Magnetic tape).
- Level 1 cache is built directly into the CPU for the fastest data access, followed by subsequent levels with more storage capacity but slower speeds.
- The CPU uses a hierarchy of memory for different types and speeds of access.
Storage Devices
- Hard Drives: Physical components storing data, including programs, pictures, documents, and operating systems. Can be internal or external.
- Solid-State Drives (SSDs): Common storage drives that are smaller, faster, and quieter than hard disk drives, using electronic memory and without moving parts.
Input/Output Devices
- Monitor: Displays information pictorially or textually.
- Computer Mouse: A hand-held pointing device that detects motion relative to a surface, controlling the graphical user interface of a computer.
