• What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in
lions [1.4K]

Answer:

Advantages of both circuit switched networks and TDM are given below:

Explanation:

Advantages of circuit switched network over packet switched network:

  • Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
  • Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.

Advantages of TDM over FDM in a circuit switched network:

  • TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
  • Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
  • In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.

O How basic blocks are identified and how the blocks are used to construct control flow graphs
OLEGan [10]

Basic blocks are identified  because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.

Note that  Basic Block is said to be a composition  of statements that is known to be one that often always executes one after other, and this is often done in a sequence.

<h3>How do you create a flow graph from the basic blocks?</h3>

Flow graph  is gotten by:

  • Lets Block B1 be the initial node and also Block B2 will tend to follows B1, so from B2 to B1 there is seen a kind of an edge.

Note that the first task is for a person to partition a sequence of three-address code and this is done into basic blocks.

Hence, Basic blocks are identified  because they are known to be a straight line that is known also as a code sequence that tends to have no branches in regards to its in and out branches and its exception is only to the entry and at the end.

Which of the following is NOT a design choice when using the ER model?
wlad13 [49]

Answer:

Relationship vs N-ary Relationship

Explanation:

It is not part of the design choice in ER model because N-ary reflects an indefinite form or better still creates an identifying attribute in an ER relationship. Example is the process of creating an auto-generated ID value
