Study Notes
Computer Networks
- Computer networks connect computers to share resources such as data, services, and devices.
- Networks are categorized by geographical coverage and purpose.
Network Types
- Personal Area Network (PAN): Connects devices in a small, private area (e.g., home). Uses Bluetooth and Wi-Fi technologies.
- Local Area Network (LAN): Connects computers within a local area (e.g., office) using a central device and cables (twisted pair, coaxial, fiber optic).
- Metropolitan Area Network (MAN): Connects LANs within a city or town using fiber optics and Gigabit Layer 3 switches.
- Wide Area Network (WAN): Spans a wide geographic area using dedicated telecommunication lines (telephone lines, leased lines, satellites). The internet is an example.
Network Components
- Networking Devices: Devices like routers and switches that facilitate communication within a network.
- Networking Media: Physical cables (like copper, fiber optic) that transmit data.
- Network Operating System (NOS): Software that manages network resources and communication.
Client/Server Roles
- Clients: Request access to resources from servers.
- Servers: Provide resources and manage access to those resources.
Hosts and Nodes
- Host: A device with an IP address that requests or provides network resources (e.g., clients, servers, routers).
- Node: Any network device that can transmit and receive data but might not have an IP address (e.g., a printer).
Network Architectures
- Peer-to-Peer (P2P): A network where hosts have no predefined roles and act as clients or servers dynamically. PANs are often P2P.
- Client/Server: A network where hosts have predefined roles (clients and servers).
Understanding Computer Networks
- Computer networks facilitate resource sharing, including data, services, and peripherals.
- Networks allow for communication across geographical distances.
- Computer network categories depend on area coverage and purpose.
Types of Computer Networks
- Personal Area Network (PAN): Connects devices in a private, protected area, often using Bluetooth or Wi-Fi.
- Local Area Network (LAN): Connects computers in a local area, often using a central device and wired connections (twisted pair, coaxial, or fiber optic cables).
- Metropolitan Area Network (MAN): Interconnects LANs within a town or city, typically using fiber optics and gigabit layer 3 switches.
- Wide Area Network (WAN): Covers a wide geographic area, using dedicated telecommunication lines like telephone lines, leased lines, or satellites. The internet is a prime example of a WAN.
Understanding Computer Network Components
- Networking Devices: Equipment that facilitates communication, such as routers, switches, hubs, and firewalls.
- Networking Media: Physical pathways for data transmission, like twisted pair cables, coaxial cables, fiber-optic cables, and wireless signals.
- Network Operating System (NOS): Software that manages network resources and allows devices to communicate.
Understanding Clients and Servers
- Clients: Devices that request access to network resources.
- Servers: Devices that provide and manage access to network resources.
Understanding Hosts and Nodes
- Host: Any device with an assigned IP address that requests or provides network resources. Clients, servers, and routers typically act as hosts.
- Node: Any device that can receive and transmit data on the network but lacks an assigned IP address.
Understanding Computer Network Architectures
- Peer-to-Peer (P2P): Also known as a workgroup, where devices have no predefined roles and act as both clients and servers, often seen in PANs.
- Client/Server: Also known as a domain-based network, where devices have predetermined roles as clients or servers. Clients request resources from servers.
