Networks Introduction

Question	Answer
What is a Network Manager?	> Way to manage other computers over a network > Can manage other computers to update software, fix problems (e.g., incorrectly setup software), or generally helping users (e.g., resetting passwords)
Why are Networks usedful for Data Exchange?	> Data can be sent between computers without the need for an intermediate device (e.g., a USB stick), or some form of external storage
What are some Examples of Resources can be Shared on a Network?	> Printers > Scanners > Internet connections etc.
What is Bandwidth and how does it affect a Network's Performance?	> Amount of data that can be transferred in a given time (like the flow of a pipe) > Greater the bandwidth, the better the potential performance > Bandwidth is shared between all active users, so too many users will slow down the network
What is Topology and how does it affect a Network's Performance?	> How the computers are laid out and connected together > Has a large impact on the network performance and reliability, due to network collisions and other factors
How do Wired / Wireless Networks Compare in Performance?	> Wired networks are usually much faster and more reliable (since interference is much less likely) > Wireless performance depends on how well the computer can pick up a signal, and any other signal interference, so is often slower by a large margin
