Study Notes
Internet vs. Intranet vs. Extranet
- The main difference between Internet and Intranet is that the Internet is a public, global network, while an Intranet is a private, limited network, typically used within an organization.
- A key feature of Extranet is that it is a private network, but accessible to partners or suppliers, and is often used for collaborative projects.
Network Characteristics
- The Internet is defined as a 'network of networks' because it connects multiple computer networks globally.
- Intranet is specifically aimed at sharing internal information among employees.
- No single agency has control over the Internet, making it a decentralized system.
Network Types
- 'Distributed' in the context of the Internet refers to the ability of the network to function without a central point of control.
- A Local Area Network (LAN) connects computers within a limited area, such as a school or office building.
- A Metropolitan Area Network (MAN) is a collection of LANs linked together within a town or city, and is distinguished by its larger geographic area.
- A Wide Area Network (WAN) allows connection to other computers over a wider geographical area, and is distinguished from LANs by its greater distance coverage.
Ownership and Accessibility
- A WAN is owned by the same organization that owns the attached devices.
- WANs are distinguished from LANs by their greater distance coverage.
Internet Characteristics
- The Internet is a global network of interconnected computers.
- The main characteristic of an Intranet is that it is a private network, accessible only to authorized personnel.
- An Extranet differs from an Intranet in that it is accessible to partners or suppliers, while an Intranet is only accessible to employees.
Data Communication
- A protocol plays a crucial role in data communications, as it defines the rules and standards for data transmission.
- The sender is the device that initiates data transmission.
- A transmission medium refers to the physical or wireless channel through which data is transmitted.
