Computer Networks and VSAT Systems

VSAT Systems

• VSAT systems allow companies full control over their communications, regardless of location, without relying on other companies.
• Businesses can use VSAT for sales and inventory information exchange, advertising, and presentations between headquarters and store managers.
• Examples include stores in Minneapolis, London, and Boston connecting to a New York headquarters via satellite.

Computer Networks

• A computer network connects two or more computers to allow data or resource sharing (like printers).
• A common type is the client-server network.
• Clients (laptops or desktops) request data or resources from servers.
• Servers provide shared services to clients.
• Large organizations assign specific tasks to servers (e.g., application server stores programs and documents).
• A print server manages printers, collects printing requests and distributes printouts.
• An email server handles incoming and outgoing emails.
• Sharing resources avoids duplication.

Network Classification

• Networks are classified by geographical area and connection method (wired or wireless).
• Wide Area Networks (WANs) connect computers over large distances (statewide or national) using phone lines, microwaves, or satellites.
