She uses the Radio-frequency identification(RFID) which is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects.These tags contain electronically-stored information.the passive tags collect energy from a nearby RFID readers interrogating radio waves.They contain an integrated circuit and an antenna which are used to transmit data to the RFID reader also called an interrogator.

The OSI model is a useful tool in troubleshooting a network because it enables you to isolate a problem to a particular software

lutik1710 [3]

Answer:

1) Layer 4, transport

2) Layer 2, datalink

3) Layer 5, session

4) Layer 7, application

Description of Problems are as below:

1) One of your servers has been exhibiting sluggish network performance. you use a network-monitoring program to try to evaluate the problem. You find considerable TCP retries occurring because the server is being overwhelmed by data, and packets are being discarded.

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Explanation:

OSI Model is a reference model to determine how applications communicate over a network. OSI consists of seven layers, and each layer performs a particular network function. The seven layers are:

Layer 7 - Application.

Layer 6 - Presentation.

Layer 5 - Session.

Layer 4 - Transport.

Layer 3 - Network.

Layer 2 - Data Link.

Layer 1 - Physical.

Layer 4, transport

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

Layer 2, Data Link

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

Layer 5, session

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Layer 7, application

Q1). Write a python program to pass a list to a function and double the odd values and half even values of a list and display li

zepelin [54]

Answer:

$\textsf{\large{\underline{Solution}:}}$

The given problem is solved using language - Python.

def f(x):

new_list=[]

for i in x:

if i%2==0:

new_list.append(i//2)

else:

new_list.append(i*2)

return new_list

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(my_list)

print('Modified List:',my_list)

$\textsf{\large{\underline{Logic}:}}$

Create a new list.
Iterate over the list passed into the function.
Check if the element is even or not. If true, append half the value of element in the list.
If false, append twice the value of the element in the list.
At last, return the new list.

There is another way of doing this - By using map() function.

—————————————————————————————

def f(x):

return list(map(lambda x:x//2 if x%2==0 else 2*x,x))

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(2my_list)

print('Modified List:',my_list)

—————————————————————————————

$\textsf{\large{\underline{O{u}tput}:}}$

Original List: [1, 2, 3, 4, 5]

Modified List: [2, 1, 6, 2, 10]

What is segmentation and paging?

iogann1982 [59]

Over the years, operating systems have sought to be more efficient, which is why it is vital that the use of main memory such as ram be as intelligent as possible, so that operating systems are more efficient.

Segmentation is a process of dividing the program into logical units, such as sub functions, arrays, variables, etc., making it possible to have processes divided into pieces so that it is easy to access each of the processes that this leads to its execution. Segmentation allows the programmer to contemplate the memory as if it had several address spaces or segments. References to memory consist of an address of the form segment number - offset.

Pagination is a technique where memory space is divided into physical sections of equal size, called page frames. The programs are divided into logical units, called pages, that are the same size as the page frames. In this way, an information page can be loaded in any page frame. The pages serve as an information storage unit and transfer between main memory and auxiliary or secondary memory. Each frame is identified by the frame address, which is in the physical position of the first word in the page frame.
