I would recommend first familiarizing yourself with the program Access by watching introductions.
If you have even more time to spare and want hands-on experience, use Wise Owl exercises. Search up college classes assignments or guides. (Boy, do they love their big workbooks.) Essentially, do practice exercises.
Answer:
The Python code with the function is given below. Testing and output gives the results of certain chosen parameters for the program
Explanation:
def first_last(seq):
if(len(seq) == 0):
return ()
elif(len(seq) == 1):
return (seq[0],)
else:
return (seq[0], seq[len(seq)-1])
#Testing
print(first_last([]))
print(first_last([1]))
print(first_last([1,2,3,4,5]))
# Output
( )
( 1 , )
( 1 , 5 )
Answer: The response that is expected when it broadcast an ARP request is one or zero.
Explanation: ARP request means Address Resolution Protocol which is a protocol responsible for the mapping of the IP(Internet protocol)address of a system to the MAC(Media Access Control) layer. Only one response is received only if the IP address is present in the ARP otherwise if the IP address does not matches then no response is returned.Thus only one or zero response can be received when a ARP request is process.
Answer:
The User Datagram Protocol (UDP) is called the connectionless protocol because:
It does not attempt to fix bad packets or resend lost packets.
Explanation:
Ports are openings or entrance doors through which data packages have access to a PC or server. TCP and UDP are transport protocols with port numbers. TCP means Transmission Control Protocol. They are used to connect two devices over the internet and other networks. UDP means User Datagram Protocol. They are used to connect applications and to speed the transfer of data. Comparatively, UDP is faster, simpler, and more efficient than TCP. TCP enables retransmission of lost data packets, which UDP cannot do.
