Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
Answer:
64 bits.
Explanation:
Secure Hash Algorithms (SHA) :- These are a family of cryptographic hash functions. There are basically four types of secure hash algorithms for generating cryptographically secure one-way hash.They are as following:-
SHA-0
SHA-1
SHA-2
SHA-3
SHA -2 consists of SHA-512 and the word size used by it is 64 bits.
Answer:
B. Role-based access controls
Explanation:
Roll-based access control is a way to control access to the network and to data which depends on the position of employees in a department. This way the permission to access information are granted according to roles that are assigned to employees. This type of access control allows access privileges to employees only to the folders and data files which they need in order to perform their tasks and it does not allow them to access the data or information which is not relevant to them. This helps the department to secure the sensitive information and data files and reduces the risk of data breaches.
Answer:
DDR3 SDRAM having twice rate of data transferring as compared to DDR2 SDRAM both have 240 pin connection. DDR3 memory power consumption is 40 % less as compared to DDR2. both are transfers data on a 64 data bits wide bus. The physical difference occur in both type a cut is present at bottom along pin in DDR2 it is occur probably in center and In DDR3 it is occur at left through center.
Answer:
interference
Explanation:
The most likely reason for the connectivity problems is interference. This interference can be caused by many factors but in this scenario the most likely factor would be the metal studs and all the metal used to create the ceiling/floor. Metal is a huge interference when it comes to wifi signals. Depending on the type of metal and the amount it can greatly diminish the signal strength or even completely prevent the signal from passing to it's destination, regardless of how close the destination device is located.
