A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). Technically, network switches operate at layer two of the OSI model.

HUB
Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
RING
The ring topology is a type of computer network arrangement where each network computer and devices are connected to each other forming a big circle. Each packet is sent around the ring until it reaches its final destination. Today, the ring topology is hardly ever used.

Focused Differentiation
•Choice to be made between focused differentiation and broad differentiation if growth required
•Difficult when the focus strategy is only part of an organisation’s overall strategy
•Possible conflict with stakeholder expectations
•New ventures start off focused, but need to grow
•Market situation may change, reducing differences between segments

Failure Strategies
•Increase price without increasing product/service benefit
•Reduce benefits whilst maintaining price
•Reduce benefits whilst maintaining price
Hybrid Strategy
•Achieve greater volumes
•Clarity about activities on which differentiation can be built (core competences)
•Reduce costs on other activities
•Entry strategy in market with established competitors

Differentiation Strategies
•Success depends on
–Identification of strategic customers and knowing what they value
–Knowing the competitors
•Narrow competitor base – focused differentiation
•Wide competitor base – address bases of differentiation valued by customers

Low Price Strategy
•Pitfalls of low price strategy
–Margin reduction (competitor reaction)
–Inability to reinvest leading to loss of perceived benefit of product
•Need a low cost base
–Low cost itself not a basis for advantage
–Low cost achieved in ways that competitors cannot match to give sustainable advantage
