The OS shell allows access to the operating system services
Answer:
FF-FF-FF-FF-FF-FF and 255.255.255.255
Explanation:
FF-FF-FF-FF-FF-FF can be defined as the layer 2 address broadcast which is often used on ethernet frames as well as help to broadcast all equipment due to the fact broadcast is made possible through Ethernet networks in which the Frames are addressed to reach every computer system on a given LAN segment as far as they are addressed to MAC address FF:FF:FF:FF:FF:FF.
255.255. 255.255 can be seen as the layer 3 address which help to address the exact same hosts because it enables the broadcast address of the zero network which is the local network due to the fact that the IP broadcasts are often used by BOOTP and DHCP clients to find and send requests to their respective servers in which a message sent to a broadcast address may be received by all network-attached hosts.
Therefore the Layer 2 and Layer 3 destination addresses which the message contain are FF-FF-FF-FF-FF-FF and 255.255.255.255
Answer:
Option B is the correct answer for the above question.
Explanation:
The control structure is a decision type structure which can be either true or false. It has two options-- If this then, does this otherwise do this. When the user wants to write he control structure then he can do this by the help of the following syntax in python language--
if(condition):
do this
else:
do this
The above question wants to ask about the concept which is used in the programming for a decision then the answer is control structure which is referred from the option B. Hence B is the correct option while the other is not because--
- Option A states about the flowchart which is the picture form of the instruction.
- Option C states about the pseudocode which is the language form of the instruction.
- The operator is also not the correct option because it is used to perform the operation.
Answer:
Disadvantage of having too many features in a language is that:
- There are many functions with same name but perform different function or task so it will create an issue or problem.
- Features do not duplicate one another as, there are different possible syntax for the same meaning.
- In a mathematical function, sometimes user function and mathematical variable name collide with language base features so it will create problem.
The answer has to be true because everything makes sense
