CHAPTER 1: EXPLORE THE NETWORK - Coggle Diagram

- - - - web serber
      - email server
      - file server
    - - Advantages:
      - Simple setup and cost-effective (no need for centralized servers).
      - Suitable for small networks (e.g., home or small office networks).
      - Devices can simultaneously act as both clients and servers.
      - Disadvantages:
      - Not scalable for large networks.
      - Less secure since all devices are equally exposed to risks.
      - Performance can degrade as the number of connected devices increases.
      - End Devices
        
        End devices are the source or destination of data in a network.
        
        Examples:
        
        PCs and Laptops: For productivity, browsing, and accessing services.
        
        Smartphones and Tablets: For mobile computing and communication.
        
        IoT Devices: Sensors, smart thermostats, and connected appliances that enable automation and data collection.
        
        Intermediary Devices
        
        These devices facilitate the movement and management of data within a network.
        
        Examples:
        
        Routers: Direct traffic between different networks, often connecting a local network to the internet.
        
        Switches: Operate within a network to connect multiple devices and manage data traffic.
        
        Firewalls: Monitor and filter incoming and outgoing traffic to enhance network security.
        
        Network Media
        
        The physical or wireless pathways through which data is transmitted.
        
        Types:
        
        Wired Media:
        
        Includes Ethernet cables (e.g., CAT5, CAT6).
        
        Reliable and less susceptible to interference.
        
        Wireless Media:
        
        Includes Wi-Fi and cellular networks.
        
        Offers mobility but can be affected by interference and range limitations.
        
        Fiber-optic Media:
        
        Uses light to transmit data, offering high speed and long-distance capability.
        
        Expensive but highly efficient for large-scale and high-bandwidth requirements.
- - - - Advantages:
        
        Flexibility for employees.
        
        Cost savings.
      - Challenges:
        
        Data security issues.
        
        Device compatibility.
  - - - Challenges:
        
        Dependency on the internet.
        
        Security concerns.
        
        Advantages:
        
        Cost efficiency.
        
        Scalability.
    - - Uses:
        - Distance learning. - Hybrid or remote work.
