  1. LAN Considerations BUS 188 Chapter 9

  2. LAN Implementation Alternatives • Dedicated servers • Non-dedicated servers • Large central computer systems • Service bureaus • Contracting out • Zero-slot LAN • Connecting computers with existing serial or parallel ports

  3. Sub-LANs • A different approach that provides a subset of LAN capabilities – good for peripheral sharing and file transfers • Has lower data transfer rates • Lower costs • Gets implemented with physical data switches • However, hard to expand • Contention problems

  4. LAN Selection Criteria • Cost • Number of workstations • Types of workstations • Number of concurrent users • Type of use • Number and types of printers • Distance and medium

  5. LAN Selection Criteria Cont. • Speeds • Applications • Expandability • Device connectivity • Connectivity to other networks • Adherence to standards • Vendor/support • Manageability • security

  6. LAN Management Tasks • Users/group oriented • Printer oriented • Hardware/software oriented • General • Backups/recovery • Education • monitoring
