1. LAN (Local Area Network)
A small network typically used within an office or building. LAN connects devices in a limited geographic area, such as an office or store.
Advantages: Fast, low-cost, ideal for small businesses.
Example: Computers connected to a printer within the same office.
2. MAN (Metropolitan Area Network)
A network that covers a broader area compared to LAN, typically a city or a group of buildings.
Advantages: Ideal for connecting branch offices within a city.
Example: A company with multiple branches in one city can use a MAN.
3. WAN (Wide Area Network)
A network that covers a vast geographical area, such as a country or a continent. The Internet is the largest example of a WAN.
Advantages: Suitable for companies with global offices.
Example: A multinational company connecting its branches across countries.
4. PAN (Personal Area Network)
A small-scale network used for personal devices, such as linking a laptop and smartphone via Bluetooth.
Advantages: Ideal for personal use.
Example: File synchronization between a smartphone and computer.
Wired Network
A network that uses physical cables (such as Ethernet cables) to connect devices.
Advantages: Stable, fast, and with minimal interference risks.
Example: Computers in an office connected via LAN cables.
Wireless Network (Wi-Fi, Bluetooth)
A network that uses wireless technology, such as Wi-Fi or Bluetooth, to connect devices.
Advantages: Flexible, perfect for areas where cables are difficult to install.
Example: A Wi-Fi hotspot in a café or office.
Intranet Network
A private network within an organization used exclusively by employees.
Advantages: Secure and restricted to employees.
Example: An employee portal for sharing internal documents.
Extranet Network
A network that allows access to external parties, such as business partners or customers.
Advantages: Facilitates collaboration with external stakeholders.
Example: Clients accessing specific documents through a portal.
Internet

Functions of a Networks
Why are networks so important for your business? Here are some of the key functions:
- Resource Sharing: You can share printers, internet connections, or even software to enhance efficiency.
- Communication and Collaboration: A network system supports fast communication through email, video calls, or collaboration apps like Slack.
- Data Storage and Access: Data can be stored centrally on a server, allowing all users to access it whenever needed.
Business Example: An intranet network in a company allows employees to share important files without having to send multiple emails.
Types of Network Architectures
Networks can also be categorized by their topology or architecture:
- Star Topology
All devices are connected to a central point (hub/switch). This topology is ideal for small businesses because it is easy to manage. - Bus Topology
Uses a single main cable to connect all devices. It is low-cost but difficult to expand. - Ring Topology
Devices are connected in a circular fashion. Each data packet passes through each device before reaching its destination. - Mesh Topology
All devices are directly connected to each other. It is highly reliable but expensive. - Hybrid Topology
A combination of two or more topologies, offering more flexibility for complex business needs.
