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.
