What is a Local Area Network (LAN)?
A network inside one organization or building.
Uses wired connections (e.g., Ethernet) to connect devices like PCs and printers to shared resources.
Offers fast, reliable data transfer.
Example: In a corporate office, LAN connects employee computers to a shared server.
What is a Wide Area Network (WAN)?
A network spanning computers in widely separate locations, such as different cities.
Connects via public infrastructure (e.g., telephone lines).
Example: A bank’s network linking offices and ATMs across cities.
What is a Virtual Local Area Network (VLAN)?
A LAN segment isolated within a larger LAN for security or organizational purposes.
Operates under one organization and isolates sensitive resources.
What is a Wireless Local Area Network (WLAN)?
Also called Wi-Fi, connects devices wirelessly through access points.
Performance depends on proximity to the router and obstructions.
Example: In a café, WLAN allows customers to access the internet wirelessly.
What is a Storage Area Network (SAN)?
A specialized network providing access to large amounts of storage.
Virtualized, so users do not need to know where data is physically stored.
Example: Data centers used by organizations.
What is a Virtual Private Network (VPN)?
Provides secure, private connections over public networks like the internet.
Encryption is crucial for maintaining security.
Example: Remote workers accessing a company’s network securely from home.
What is a Personal Area Network (PAN)?
Connects devices for one user or a family, typically via a wireless router.
Example: Connecting a phone, smartwatch, and laptop in a home.
What is a Peer-to-Peer Network (P2P)?
Connects devices as equals without a server.
Commonly used for file sharing over the internet.
Example: Torrenting files directly between users.
How has globalization been accelerated by network development?
Technical advances in networks, such as LAN, WAN, and the internet, enable faster communication and resource sharing.
They connect businesses, people, and services globally, driving economic and cultural integration.
What is Internet?
The internet is a globally connected network system that uses the TCP/IP protocols to transmit data via various types of media. (Network of networks)
What is Intranet?
A private network used by an organization to share information and resources internally among employees.
What is Extranet?
