Answer:

A, B and E

Explanation:

Option A is a correct choice, this is because using an unknown device and connecting it to a network may cause malware to spread on the network or allow a third party unauthorised access to the network.

Option B is also very important because it means that no equipment will be tampered with, keeping it secure is essential.

Option C is not correct as it is simply not possible.

Options D and E are, in my opinion, both correct but I would see how option E is more viable than option D.

Option E is a method hackers use to gain access or data from devices, they do this by making a network that is free and open to everyone and when a device connects, all the data is routed through that network and the person who created it (this is called a man in the middle attack).

Hope this helps!

Computer system with a 32-bit logical address and 4k-byte page size. assume that each entry of a page table consists of 4bytes.
Annette [7]

The number of bits in the physical address is 26 bits. The number of entries in a page table is \mathbf{2^{20}} entries. The size of the page table in a one-level paging scheme is 4MB.

<h3>
What is paging in Operating System?</h3>

Paging is a storage method used in operating systems to recover activities as pages from secondary storage and place them in primary memory. The basic purpose of pagination is to separate each procedure into pages.

We are given the following parameters:

  • 32-bit logical address
  • Page size = 4 KB = \mathbf{2^{12} \ bytes }
  • Size of each Page table entry = 4 bytes

Suppose the system supports physical memory size = 64 MB = \mathbf{2^{26} \ bytes}

Thus, the number of bits in the physical address is computed as:

= \mathbf{log_2 \{Physical-memory-size\}}

=\mathbf{log_2(2^{26})}}

= 26 bits

The number of entries in a page table = logical address space size/page size

The number of entries in a page table \mathbf{= \dfrac{2^{32}}{2^{12}}}

\mathbf{=2^{20}} entries

In a one-level paging scheme, the size of the table is:

= entire no. of page entries × page table size

= \mathbf{2^{20}\times 4 \ bytes}

= 4 MB

b.

suppose that this system supports up to 2^30 bytes of physical memory.

  • The size of the page table will be the same as 4 MB due to the fact that the number of entries, as well as, the page table entry size is the same.

Since the size of the page table surpasses that of a single page. A page cannot include a whole page table. Therefore, the page table must be broken into parts to fit onto numerous pages, and an additional level of the page table is required to access this page table.

  • This is called the Multi-Level Paging system.

Therefore, we can conclude that the number of bits in the physical address is 26 bits, the number of entries in a page table is \mathbf{2^{20}} entries, and the size of the page table in a one-level paging scheme is 4MB.

True or False?
Nadya [2.5K]

False.

The different between break and continue instruction is that with break you exit the loop, and with continue you skip to the next iteration.

So, for example, a loop like

for(i = 1; i <= 10; i++){

   if(i <= 5){

       print(i);

   } else {

       break;

   }

}

will print 1,2,3,4,5, because when i=6 you will enter the else branch and you will exit the loop because of the break instruction.

On the other hand, a loop like

for(i = 1; i <= 10; i++){

   if(i % 2 == 0){

       print(i);

   } else {

       continue;

   }

}

Will print 2,4,6,8,10, because if i is even you print it, and if i is odd you will simply skip to the next iteration.

explain the joke, “There are 10 types of people in the world: those who understand binary and those who don’t.”
tino4ka555 [31]

Answer:

Binary is made up of only 2 digits: a one and a zero. 1011 is eleven in our counting system.

So 10 in binary = 2 in our counting system.

Read the joke as follows. There are 2 types of people in the world: those who  understand binary and those who do not.

I guess it's not really that funny, but computer programmers like it.

You are configuring a network attached storage (nas) appliance. what file sharing protocol(s) could you use to allow access to w
kicyunya [14]

Most clients should support Server Message Block (SMB)/Common Internet File System (CIFS).

<h3>What is CIFS used for?</h3>

Common Internet File System (CIFS) is a network filesystem protocol used for providing shared access to files and printers between machines on the network. A CIFS client application can read, write, edit and even remove files on the remote server.

<h3>What are CIFS servers?</h3>

CIFS stands for “Common Internet File System.” CIFS is a dialect of SMB. That is, CIFS is a particular implementation of the Server Message Block protocol, created by Microsoft.
