  1. Do they use key words from the title or question?

  • Discuss the factors determining network specification for a small business.

    "In conclusion, if cost is your main issue and you are not too concerned about the flexibility of your network, a wired LAN is probably the best option. However, the cost of building and implementing a wireless network is decreasing as technology becomes more advanced, so is definitely worth considering if prepared to pay a small amount more. Security on both types of networks is moderate - ultimately, regardless of whether you go for wireless or wired, your network will be as secure as you are prepared to make it, with the introduction of firewalls etc. Both type of networks perform well and are generally similar in terms of reliability, although it is important to be aware of problems with newer hardware. Installing a wired network is more time consuming and costly, due to amendments to furniture/walls to accommodate cabling."
