What is a Network?

A network is a collection of interconnected devices that communicate and share resources. These devices, often referred to as nodes, can include computers, servers, smartphones, printers, and even IoT devices like smart thermostats.

Key Characteristics of Networks:

• Interconnectivity: Networks link multiple devices together.
• Resource Sharing: Networks enable users to share files, printers, and internet connections.
• Scalability: Networks can grow by adding new devices without disrupting existing connections.

Types of Networks:

1. LAN (Local Area Network):
   • Limited to a small area like an office or home.
   • Example: Office Wi-Fi network.
2. WAN (Wide Area Network):
   • Covers large areas, often connecting cities or countries.
   • Example: The internet.
3. MAN (Metropolitan Area Network):
   • Covers a city or a campus.
   • Example: City-wide Wi-Fi network.
4. PAN (Personal Area Network):
   • Limited to an individual’s personal devices.
   • Example: Bluetooth connections between a phone and a smartwatch.

What is Networking?

Networking refers to the practice of designing, implementing, and managing networks to enable communication between devices. It encompasses both hardware and software aspects.

Key Elements of Networking:

• Routers: Direct data packets between networks.
• Switches: Connect devices within a single network.
• Protocols: Rules for data exchange (e.g., TCP/IP, HTTP).
• Cabling/Wireless: Physical or wireless means of connecting devices.

Benefits of Networking:

• Faster communication.
• Centralized data access.
• Cost efficiency by sharing resources.
