Explanation:
Because it is a broadcast packet, it is sent to a special MAC address that causes all machines on the network to receive it. Any machine with the requested IP address will reply with an ARP packet that says "I am 192.168. 1.1", and this includes the MAC address which can receive packets for that IP.
Answer:
a)
inv([1 1; 100 100])
warning: matrix singular to machine precision
warning: called from ATest at line 1 column1
ans =
Inf Intf
Inf Inf
b)
A = [4, 9; 5, 11]
B = inv(A)
A*B
B*A
4. 9
5 11
-11.0000 9.0000
5.0000 4.0000
ans . 00000 -0.00000
0 . 00000 1.00000
ans 1.00000 0.00000
0.00000 1.00000
c)
x = [5; 10]
y = A*x
x = [5; 10]
y=
110 135"
d)
B * y is
5.0000
10.0000
e)
B * y
ans 5.0000
10.0000
Virtual memory frees up RAM by transferring data that hasn't recently been used to a storage device, such as a hard disk or solid-state drive (SSD). Virtual memory is useful for multitasking, running large programs, and speeding up the system.
<h3>
What is the role of virtual memory in disk storage space?</h3>
Virtual memory fulfills two functions. First, by using disk, it enables us to increase the utilization of physical memory. Because each virtual address is converted to a physical address, it also enables memory protection.
An operating system may load programs larger than its physical memory thanks to virtual memory, which is its fundamental benefit. The users get the idea that the machine has boundless memory. Additionally, it offers memory security.
Therefore, operating systems move code and data, as necessary, to a portion of the disk that is used as if it were memory, not just disk storage space.

Port replicator is the type of device should you choose to provide all the functionality above.
<h3>What does a port replicator do?</h3>
- A tool used to connect a laptop's accessories rapidly. Permanent connections are made to the port replicator, which is connected to the laptop via the USB port, by the keyboard, mouse, network, monitor, printer, and port.
- A docking station's functionality may be partially or entirely provided by a port replicator, and the words are interchangeable.
- However, a port replicator often offers a universal solution for all laptops through USB, in contrast to a docking station that connects to the computer using a proprietary connector. check out docking station.
- A port replicator is an add-on for a notebook computer that enables many devices, such a printer, big screen, and keyboard, to be attached at once.
