Study Notes
Computer Network Overview
- A computer network is a collection of two or more computers linked together to exchange data and resources.
- The arrangement of computers in a network, alongside the distribution of tasks among them, is termed network architecture.
Purpose of Communication Channels
- Communication channels facilitate the transmission of data between devices in a computer network.
- These channels are critical for connectivity and effective data exchange.
Local Area Network (LAN)
- LAN (Local Area Network) enables personal computers and workstations to share data, tools, and applications within a limited area.
- LANs are relatively simple to set up and manage.
Main Functions of Network Systems
- The primary function of a computer network system is to allow sharing of resources and data among connected devices.
- Enables efficient communication, resource sharing, and collaborative work.
Metropolitan Area Network (MAN) vs. Wide Area Network (WAN)
- MAN spans a larger geographic area than a LAN but is smaller than a WAN, serving cities and large campuses.
- WAN covers extensive geographic areas, often connecting multiple MANs or LANs across countries or continents.
Internet as a Network Type
- The Internet is considered a WAN, connecting millions of networks globally, allowing for wide-ranging communication and data transfer.
Connecting Devices in a Network
- A switch is the key device responsible for connecting multiple devices on a network, enabling direct data transfer from one device to another.
- A hub can also manage network connections, distributing a single connection to several devices, though less efficiently than a switch.
Communication Cables
- Twisted-pair cables and coaxial cables are the primary types of cables utilized for transmitting communication impulses within LANs.
- These cables are essential for maintaining connectivity and data integrity.
Linking LAN to Internet
- A router is the component used to connect a Local Area Network (LAN) to the Internet, directing data traffic effectively.
Speed Measurement
- The speed of data transfer in a Metropolitan Area Network (MAN) is typically measured in megabits per second (Mbps).
