Answer:
def prime_generator(s, e):
for number in range(s, e+1):
if number > 1:
for i in range(2, number):
if (number % i) == 0:
break
else:
print(number)
prime_generator(6,17)
Explanation:
I believe you want to ask the prime numbers between s and e.
- Initialize a for loop that iterates from s to e
- Check if the number is greater than 1. If it is, go inside another for loop that iterates from 2 to that number. If the module of that number to any number in range (from 2 to that number) is equal to 0, this means the number is not a prime number. If the module is not equal to zero, then it is a prime number. Print the number
The recommendation of the instructor for Gaven to include a personal statement in his work portfolio will allow him to identify his career goals. If he is unable to show this to his work portfolio then he may simply state it in the personal statement. Thus, the answer to this item is letter A.
Answer:
Chord is a set of rules for a peer-to-peer distributed hash table it collects key-value sets by allotting keys to several computers (known as "nodes"); a node will collect the values for all the keys for which that is reliable. Chord defines how keys are allocated to the nodes, and how a node can determine the value for a distributed key by first locating the node liable for such key.
Explanation:
A chord is a peer-to-peer lookup service. It Resolves the difficulty of establishing a data item in a combination of shared nodes, considering various node arrivals and removals The most crucial operation in most peer-to-peer method is the efficient position of data objects.
It is able of supporting only one operation i.e. given a key, it maps the key on a link.
Algorithm:
Algorithm shows working of the chord:
// x is a node used to find successor of id
x.find_successor(id)
if (id (x; successor])
return successor;
else
// query is being delivered around the circle
entrance successor.find_successor(id);
The allocation methods define how the files are stored in the disk blocks.
There are three main disk space or file allocation methods:
1.Contiguous Allocation-in this scheme,each file occupies a set of blocks on the disk. For example if a file requires x blocks and is given a block y as the starting location,then the blocks assigned to the file be :x,y+1,y+2,......y+x-1.
This means that given the starting block address and the length of the file(in terms of blocks required) we can determine the blocks occupied by the file.
Advantages
-both the sequential and direct accesses are supported
-this is extremely fast since the number of seeks are minimal because of contiguous allocation of file blocks.
2.linked allocation-in this scheme,each file linked list of disk blocks which need not be contiguous disk blocks can be scattered anywhere on the disk.
Advantages
it is very flexible in terms of file size.file size can be increased easily since the system does not have to look for a contiguous chunk
of memory.
this method does not suffer from external fragmentation and it makes it relatively better in terms of memory utilization.
3.Indexed Allocation-in this scheme,a special block known as the index block contains the pointers to all the blocks occupied by a file.Each file has its own index block.the entry in the index block contains the disk address of the block
Advantages
it supports direct access to the blocks occupied by the file and therefore provides fast access to the file blocks
it overcomes the problem of external fragmentation.
Explanation:
One of the main characteristics of computer viruses is related to the fact that they are programs created by hackers that attack the code of a computer, infecting files on the computer's hard drive or its source code. Once the virus has been copied onto the computer, it can contaminate other computers that come into contact with the machine.
