Answer:
Advantages of a circuit-switched network over a packet-switched network are:
- In Circuit-switched networks, resources needed to provide communication between the end systems for the duration of the session are usually reserved unlike in packet-switched networks where they are not reserved.
- Circuit-switched networks have faster communication, so they can be used for Voice/Video calls
- Circuit-switched networks have less errors in communication
- Circuit-switched networks are more suitable for real-time services. Packet-switched networks are simpler, more efficient, and less costly to implement. They also offer better sharing of transmission capacity than circuit-switched network
Advantages does TDM have over FDM in a circuit-switched network are;
- In TDM, all connections operate at the same frequency , but In FDM, all connections operate at different frequencies
- In TDM there is low interference between the signals that are being multiplexed as compared to FDM.
- In TDM, bandwidth is saved by allocating time slots on demand dynamically
- TDM systems are more flexible than FDM
Answer:
Explanation:
There are all sorts of possibilities for, say, inserting new technologies into existing processes. But most of these improvements are incremental. They are worth doing; in fact, they may be necessary for survival. No self-respecting airline, for instance, could do without an application that lets you download your boarding pass to your mobile telephone. It saves paper, can't get lost and customers want it.
But while it's essential to offer applications like the electronic boarding pass, those will not distinguish a company. Electronic boarding passes have already been replicated by nearly every airline. In fact, we've already forgotten who was first.
Answer:
Option D is correct i.e., =DATEDIF(C2, $AE$2, "y").
Explanation:
The user's supervisor well into the following department tells him to compose the feature which measures the amount that times staff has served in their company utilizing the DATEDIF feature. Consider whether C2 includes the hiring dates for that staff and then that cell $AE$2 includes the cut-off point for whom to evaluate the hiring time with the duration of the service.
So, therefore the following option is correct according to the given scenario.
Search for it in the start menu. Once you find it, right click and press "Pin to taskbar."
Im not sure about B. but if you can choose mutiple pick C,D,E but if you can shoose only one than pick A
