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.
Answer: (D) Select and install an App Exchange product to meet the contract generation needs.
Explanation:
The App exchange is the type of salesforce market place in the cloud platform and it included various types of cloud application and the services. We can select and then install the app exchange different types of product and services to meets the given generation needs.
The app exchange service is mainly used in the universal container that mainly needs for generating the document in the system. The user can able to install and access this type of app salesforce easily.
Therefore, Option (D) is correct.
Answer:
if (x > 7 && Math.sqrt(x) < 3)
Explanation:
The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.
So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.
Answer:
sample_str = "Help me pass!"
first_chars = sample_str[0:4]
print('First four character: ', first_chars)
Explanation:
sample_str = "Help me pass!"
first_chars = sample_str[0:4]
H has index 0, e has index 1, l has index 2, p has index 3. the space has an index as well, etc.
