Study Notes
WAN and Network Architecture
- WAN (Wide Area Network) connects multiple LANs (Local Area Networks) over large distances.
- Network Architecture is the design and configuration of a computer network, also called network model or network design.
- Two main types of network architecture:
- Peer-to-Peer Network: Connects fewer than 10 computers with equal capabilities.
- Client/Server Network: One computer (server) provides services to other requesting computers.
Network Topology
- Topology refers to the physical or logical arrangement of network devices, cables, and nodes.
- Different types of network topologies include Bus, Ring, Star, Extended Star (Tree), and Mesh.
Bus Topology
- Features a single central cable connecting all devices.
-
Advantages:
- Simple, inexpensive, easy to implement and extend.
- Suitable for temporary networks; does not affect other stations if one fails.
-
Disadvantages:
- Challenging to administer and troubleshoot; limited cable length.
- A break in the cable can incapacitate the entire network; no redundancy.
Ring Topology
- All nodes are connected in a closed loop.
-
Advantages:
- Organized structure with better performance than Bus topology.
- Does not require a server for connectivity; adding components does not disrupt the network.
-
Disadvantages:
- Data must pass through all nodes, slowing down communication.
- a failure at any node affects the entire network.
Star Topology
- Devices are connected to a central device (hub or switch).
-
Advantages:
- Superior performance compared to Bus topology; easy to add nodes.
- Centralized management allows better monitoring.
- Failure of one node does not affect the network.
-
Disadvantages:
- Central device failure causes total network failure.
- Costs increase due to reliance on hub or switch.
Extended Star Topology (Tree)
- A hybrid of star topology that allows easier network expansion.
-
Advantages:
- Existing networks can be easily expanded; suitable for temporary use.
-
Disadvantages:
- Requires technical expertise for configuration; maintenance can be complex.
Mesh Topology
- All devices are interconnected, providing multiple pathways between nodes.
-
Advantages:
- Faster message transmission; multiple connections allow concurrent communication.
- New nodes can be added without disrupting existing connections.
-
Disadvantages:
- High maintenance due to numerous connections.
Networking Basics
- Data: Information collected for analysis, including text, numbers, or images.
- Packet: Unit of data routed between devices on a network.
- Ethernet: Local area network technology.
- Bandwidth: Communication speed; typically measured in bits per second (bps).
- Network Host: Any device connected to a network.
- Wi-Fi: Wireless networking technology using radio waves for connectivity.
- Internet Service Provider: Company providing internet access (e.g., PLDT, SMART).
- Broadband: Describes high-speed internet connections.
- Workstation: A computer designed for technical use, often multi-user capable.
- Protocol: Rules for data exchange over a network; common example is HTTP.
- MAC Address: Unique identifier assigned to network interface cards.
Types of Networks
- Local Area Network (LAN): Connects devices within a limited area (e.g., homes, offices).
- Metropolitan Area Network (MAN): High-speed network covering a city or town, connecting multiple LANs.
- Wide Area Network (WAN): Covers large geographic areas; combines various media such as telephone lines and radio waves.
