Study Notes
Interconnecting Computers
- A computer network allows computers to communicate and share resources
- Nodes are connection points on the network that can receive, create, send or store data
- Transmission Media connects devices using wires, cables or radio waves
- Protocols govern how devices communicate
- Networks allow resource sharing, communication, data exchange, and information sharing over broad areas.
Key Components of a Computer Network
- Computers
- Cables connecting computers
- Network Interface Card (NIC) formats data, sends data, and receives data at the designated node
- Switches
- Operating System (OS) software
Benefits of Computer Networks
- Sharing resources like printers and software
- Connectivity allowing communication between computers
Sharing Resources
- Hardware such as printers, modems, fax machines, CD-ROM players, etc.
- Software reduces the cost of installation.
Additional Benefits of Computer Networks
- Increased speed
- Reduced cost
- Improved security
- Centralized software management
- Flexible access
Disadvantages of Computer Networks
- High installation cost
- Requires time for administration
- Server failures
- Cable faults
Types of Computer Networks
- Local Area Network (LAN): Used for communication in an office building or home
- Metropolitan Area Network (MAN): Spans a larger area than a LAN, like a whole city
- Wide Area Network (WAN): connects multiple LANs together, the internet is the world's most popular WAN
- Personal Area Network (PAN): Connects a single persons' devices like a Bluetooth headset to a phone
Local Area Network (LAN)
- Enables sharing of resources like files and hardware
- Advantages: speed, cost efficiency, security, email, resource sharing
- Disadvantages: expensive installation costs, requires administrative time, file server failure, potential cable breakage
Metropolitan Area Network (MAN)
- Optimized for a large geographical area
- Examples include high-speed DSL and cable TV networks
Wide Area Network (WAN)
- Multiple LANs connected through devices like bridges, routers, and gateways, enabling them to share data
- The internet is the most widely known WAN
