NETWORK

A network is a collection of interconnected devices that communicate and share resources. It’s like a digital highway that connects computers, servers, and other devices, allowing them to exchange information and perform various tasks.

Key Components of a Network:

• Nodes: Individual devices, such as computers, smartphones, or servers,
• Links: The connections between nodes, often cables or wireless signals.
• Protocols: The rules and standards that govern communication within

Types of Networks:

• Local Area Network (LAN):  confined to a small geographic area, like a home or office.
• Wide Area Network (WAN): that spans a large geographic area, such as a country or the entire world. The internet is the largest WAN.
• Metropolitan Area Network (MAN): that covers a city or a large campus.
• Personal Area (PAN): That connects devices within a short range, like Bluetooth devices.

Benefits of Networking:

• Resource Sharing: Sharing hardware (printers, scanners) and software (files, applications) across
• Communication: Email, instant messaging, video conferencing, and other forms of communication facilitated
• Centralized Management: Easier administration and security
• Collaboration: Working on projects together, sharing information
• revolutionized the way we live and work, enabling global connectivity, remote work, and digital transformation.
