Study Notes
Hardware Components
- Hardware: physical parts of a computing device
- Digital devices that can be touched, including:
- Desktop computers
- Laptop computers
- Mobile phones
- Tablets
- E-readers
- Storage devices like USB drives
- Input devices like keyboards, mice, scanners, styluses
- Output devices like printers and speakers
- Ports: Allow devices to be added for input and output to connect to the motherboard, such as USB and HDMI ports
- Wireless
- Bluetooth:
- Connects devices to each other within 10-100 meters
- Requires each device to have a Bluetooth chip and to be 'paired'
- WiFi:
- Connects devices to each other and the internet
- Communicates through the local WiFi network
- Bluetooth:
Internal Hardware Components
- Motherboard: The main circuit board that holds the CPU, memory, and storage components; everything connects to it.
- CPU (Central Processing Unit): Carries out commands sent to it by the software and returns results.
- Speed measured in Hertz.
- CPU chips can have multiple processor cores, such as quad-core or Core i9 (with 16 cores), which increases speed
- Memory (RAM - Random Access Memory):
- Temporary working area where applications are loaded to run faster.
- When the computer is powered off, RAM is cleared.
- Bigger RAM is faster
Hardware: Storage
- Hard Disk (HD): Longer-term, permanent storage of data; uses spinning disks.
- Solid State Drive (SSD): Lighter and faster than HD; no moving parts.
- Removable Media: USB drives that can be connected and removed for use on different computers
Storage Measured in Bytes
- Digital devices process electronic signals in 1’s and 0’s called bits.
- This is called Binary.
- Eight bits = 1 byte
- Binary Prefixes:
- Kilobyte (KB): one thousand bytes
- Megabyte (MB): one million bytes
- Gigabyte (GB): one billion bytes
- Terabyte (TB): one trillion bytes
Software
- Software: Set of instructions that tells the hardware what to do.
- Two main types of software:
- Operating Systems
- Application Software
- Productivity Software
- Utility Software
- Programming Software
- Applications for the Enterprise (ERP)
Software: Operating Systems
- All devices have an operating system that manages the hardware.
- Creates the interface between the hardware and the user.
- Key Functions:
- Manage the hardware
- Provide the user-interface components
- Provide a platform for software developers to write applications
- Examples: Microsoft Windows, Apple Mac OS, and Linux
Software: Application Software
- Software that allows users to accomplish a goal or purpose.
- Three Categories:
- Productivity software: Helps employees complete their job duties efficiently, such as Microsoft Office.
- Utility software: Fixes or modifies a computer, such as antivirus software.
- Programming software: Helps to make more software. Programmers can code, test, and convert into a format the computer will understand. Usually free from the company that developed the programming language.
- Enterprise Application Software:
- Enterprise Resource Applications (ERP)
- Customer Relationship Management (CRM)
- Supply Chain Management (SCM)
- Mobile Applications
Software: Enterprise Application Software
- Enterprise Resource Applications (ERP): Provide a common application that supports functions across the entire enterprise for a company’s employees.
- Can contain the general ledger and its subsidiaries such as accounts payable, accounts receivables, etc.
- Builds in best business practices for an enterprise.
- SAP is the most popular ERP.
- Customer Relationship Management (CRM): Manages an organization’s customers.
- Personalizes the relationship with the customer.
- Example: Salesforce
- Supply Chain Management (SCM): Manages an organization’s links between its suppliers, manufacturing facilities, and distributors.
-
Organization*
Suppliers Manufacturing Facilities Distributors
- ERP may include CRM & SCM
Cloud Computing
- Internet-based applications, services, and data storage.
- Example: Email, Google Drive.
- Advantages:
- No software to install or upgrade.
- Access it any time with internet access.
- No need to worry about losing data if your hard drive crashes.
- Quick access to new apps.
- Disadvantages:
- Your information is stored on someone else’s computer - how safe is it?
- Internet access is required.
- Relying on someone else to provide these services.
Open Source Software vs. Closed Source Software
- Open-Source Software:
- Code is shared with everyone to use and add features or fix bugs.
- Large programmer groups can fix bugs and add features.
- Software is available for free.
- Source code can be reviewed prior to installing.
- May increase the risk of attack as everyone knows how your software works.
- Examples: Firefox browser and Linux operating system.
- Closed-Source Software:
- Company that developed the software provides technical support.
- Employs a large number of programmers to enhance the product.
Information Systems Emerging Trends
- Smartphones:
- Mobile use is climbing.
- Mobile commerce is 72.9%* of all e-commerce traffic.
- Internet of Things:
- A network of billions of devices collecting data.
- Examples: Fitness trackers, apps to close garage doors, refrigerators with grocery lists, thermostats, home security, and medical devices.
