Connectivity

Cost

How the network can be connected to by devices.

E.g. A user with a tablet for email & web access will need a wireless connection method.

How much purchasing and running the network will cost you or your business.

E.g. When setting up a WAN, a dedicated private connection would be much more expensive than a VPN.

Specification

The specific requirements for the network, in terms of data transfer speed, maximum bandwidth, power consumption & functionality.

E.g. A business network installing a LAN for file sharing will need a file server with certain hardware requirements.

Efficiency

How effectively tasks can be completed when using a network with as little wastage of resources.

E.g. An old-fashioned dial-up network waste time while waiting for a connection to be made.

User Needs

What actual tasks the user wants to perform using the network.

E.g. A graphic design business will need to transfer large files over the network and so will need a high bandwidth.

Compatibility

Factors affecting implementation include timescales, testing & downtime.

E.g. When choosing an ISP, the timescales involved with when they can activate your connection may affect your choice of supplier.

Network Performance

Productivity

The features & components of a network can affect its performance. For example:

  • A servers CPU/RAM being overloaded.
  • A slow data transmission method.
  • Firewalls slowing down data while checking.
  • SOHO networking equipment.

How quickly tasks can be completed when making use of the network.

E.g. An unreliable network that goes down regularly will reduce productivity.
