Networking & Servers

Key Components

  • Servers: Powerful computers that provide resources, data, and services to other computers (clients) over a network. Types include web servers, database servers, and application servers.
  • Network Switches: Devices that connect multiple devices on a local area network (LAN) and use packet switching to forward data to the destination device.
  • Routers: Devices that connect different networks, directing data packets between them, typically between a local network and the internet.
  • Firewalls: Security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules, protecting the network from unauthorized access.
  • Access Points: Devices that allow wireless devices to connect to a wired network using Wi-Fi.

Benefits

  • Resource Sharing: Enables sharing of resources such as files, applications, and hardware (e.g., printers) among multiple users.
  • Improved Communication: Facilitates communication through email, instant messaging, and collaboration tools.
  • Scalability: Easily expand network capabilities and add new devices without significant infrastructure changes.
  • Centralized Management: Simplifies the management of network resources and security policies from a central location.
  • Data Security and Backup: Ensures data is stored securely on servers with regular backups to prevent data loss.
