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
This is how I would go about it:
1. Ask user to key in numbers. I could take each number in a single line.
2. save each input in a vector.
3. print out the vector starting at location (vector.size()-1) to location 0
Answer:
Structured programming also known as Modular programming in which the program is made as a single structure.The execution is instruction by instruction.It mainly focuses on improving the quality,clarity and development time of a computer program.
The top-down approach works by breaking a complex algorithm into smaller parts called modules. The modules keep breaking until there is no space left for breaking them without hindering the originality.The breaking of the modules is prohibited after achieving a certain level of modularity . C language uses this approach.
Bottom up works exactly opposite of how the top-down approach works.This approach works in the most elemental level of solving a problem and going up with combination of several parts of the solution to achieve required results.
