Answer:
is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer.
2. Data link Layer.
3. Network Layer.
4. Transport Layer.
5. Session Layer.
6. Presentation Layer.
7. Application Layer.
Hence, the Open Systems Interconnection (OSI) Reference Model is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Additionally, each layer has its unique functionality which is responsible for the proper functioning of the communication services.
Answer:
Encryption
Explanation:
Encryption is a term in the field of computer security (Cryptology) this is a process of encoding information in a way that hackers and eavesdroppers cannot read. The process of encryption involves a plain text (message) been converted into a scrambled text (cipher text) with an encryption algorithm (key) in this way, if the message is intercepted by a hacker he/she is unable to read the contents. Only the authorized party with a decryption key will be able to decrypt back to a plain text and read the contents of the message

Answer:
#include <stdio.h>
void printValues ( unsigned char *ptr, int count) // count is no of cells
{
for(int i=0; i<count; i++) {
printf("%d ", ptr[i]);
}
}
int main ( )
{
unsigned char data[ ] = { 9, 8, 7, 5, 3, 2, 1} ;
printValues( data, sizeof(data)/sizeof(data[0]) );
}
Explanation:
Remember that the sizeof() mechanism fails if a pointer to the data is passed to a function. That's why the count variable is needed in the first place.
Answer:
Tracks
Resilient File System (ReFS)
Explanation:
- Concentric circles on a disk platter where data is stored is called Tracks
- The new file system developed for Windows Server 2012 is called Resilient File System (ReFS). It allows increased stability for disk storage and improved features for data recovery and error checking
