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 callsCircuit-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 frequenciesIn 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 dynamicallyTDM systems are more flexible than FDM

Explanation:

(A) In its simplest term, packet switched network allows packets to be broken into smaller bits and then each bit is made to be sent independently across the network. In this type of network, communications between communicating devices might not necessarily be set up before communication can be initiated.

On the other hand, in a circuit switched network, communications between communicating devices must be set up before communication can be initiated. An example of this is the analog telephone network communication where there has to be a connection between the two end telephones before communication can begin.

The following are the advantages of circuit switched network over a packet switched network;

i. Since there is a need to establish connection before communication and once connection is made communication starts, circuit switched experiences lower delay compared to packet switched network.

ii. Also, since there is a need to establish connection before communication, a circuit switched network provides more data transmission reliability than a packet switched network.

iii. Circuit switched networks can be used for real time delivery of data while packet switched networks cannot be used.

(B) TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two common methods of combining multiple signals into a single signal - this is called multiplexing. They both act by dividing channels.

TDM splits and assigns time slices to each channel while FDM splits the channel into two or more non-overlapping ranges of frequency.

The following are the advantages of TDM over FDM in a circuit switched network;

(i) TDM provides flexibility than FDM

(ii) TDM provides efficiency by logically assigning time slices to signals according to how much bandwidth they need. This is an advantage that is lacking in FDM.

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server. so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words. size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words. size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
