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.
Test your knowledge on types of information forms and the devices involved in the transmission process like sender, receiver, and transmission medium.
