Introduction to Software & Network Setup

PRC 110: Software Skills Practicum

🎯 Learning Objectives

By the end of this session, you will be able to:

  • ✅ Distinguish between System and Application software.
  • ✅ Install common software (MS Office, SPSS).
  • ✅ Configure Network Settings (IP Address).
  • ✅ Secure your computer (Firewall, Antivirus).

💻 What is Software?

Software is the set of instructions that tells the hardware what to do.

System Software

Runs the hardware and provides a platform for applications.

  • OS: Windows, macOS, Linux
  • Drivers: Printer driver, Graphics driver
  • Utilities: Antivirus, Disk Cleanup

Application Software

Helps users perform specific tasks.

  • Productivity: MS Word, Excel
  • Business: Accounting, CRM
  • Communication: Zoom, Outlook

🛠️ Installing Software

Before installing, always check:

  • System Requirements: OS, RAM, Disk Space.
  • Admin Rights: Do you have permission?
  • Source: Is it official and safe?

Example: Installing MS Office

  1. Download installer from office.com (or insert media).
  2. Run `Setup.exe` as Administrator.
  3. Follow prompts and enter Product Key if required.
  4. Wait for installation to complete.

🌐 Network Configuration

IP Address (Internet Protocol)

A unique address for devices on a network (e.g., `192.168.1.100`).

Static IP

  • Manually assigned.
  • Doesn't change.
  • Good for printers/servers.

Dynamic IP (DHCP)

  • Automatically assigned.
  • Changes periodically.
  • Standard for user devices.

    • ⚙️ Setting Up an IP Address

    Control Panel > Network & Internet > Network Connections

    
1. Right-click Adapter > Properties
2. Select "Internet Protocol Version 4 (TCP/IPv4)"
3. Click Properties
4. Choose "Use the following IP address" (for Static)
   OR "Obtain an IP address automatically" (for Dynamic)

    Verify with Command Prompt: `ipconfig`

    🛡️ Computer Security

    Firewall 🧱

    Monitors network traffic and blocks unauthorized access.

    Windows Firewall: Can blocking/allow specific apps.

    Antivirus 🦠

    Protects against malware, viruses, and ransomware.

    Examples: Windows Defender (Built-in), Avast, McAfee.

    🧪 Unit 1 Practicum

    Hands-on Exercises

    1. Check System Specs: Find your OS version and RAM using Settings.
    2. IP Config: Open CMD and find your IPv4 address using `ipconfig`.
    3. Ping Test: Check internet connectivity: `ping google.com`.
    4. Software Install: Download and install a safe utility (e.g., 7-Zip or VLC) from specific site.
