Confusing words

1. How long has the internet been inaccessible from within the local LAN? This inaccessibility can be due to different reasons: problems at your ISP, a defective router, a configuration error, whatever. It clearly means that internet is not accessible to ALL users, so if one guy cannot reach one or more websites, it should not be counted.

2. How long has a part or all of your network been unavailable? So again, for any reason, like a defective hub, a faulty cable, or a misconfigured router. And again, not counting the one guy that has a faulty patchcable.

3. This depends a bit of what connection you're talking about. Suppose it's about your 1 Mb/s internet connection: if you're constantly noticing 0,9 Mb/s passing through it, itis used quite efficiently, but with hardly any room for growth. Suppose it's about your local network, it again depends. Ethernet is pretty heavily used at about 10-20%, Token Ring can safely go up to 50% or more. You'll need either information from a router with management capabilities, or from some sniffer software. The average use indicates how much traffic is really going through your cables, and is needed to determine if you should change or upgrade or add anything.

1) Downtime for Internet is the time that the internet was unavailable as a resource. That is, not how long the internet was down but how long your connection to it was unavailable.

2) Downtime for internal network is the ammount of time network connectivity was lost between two or more computers on the local network.

3) Bandwidth is the amount of network traffic used. For example if you use (on average) 40 Mbits per second of a 100Mbit ethernet link you would have 40% bandwidth usage.
If these are contractual terms then I would get them clarified before accepting. Some major questions would be "What constitutes downtime?" Is it when all users cannot get access or maybe 1 or more. This is all open to interpretation and depends onthe terms of reference. If you need a clearer answer I would have no know the context they are mentioned in.
