Answer:
Explanation:
It can be said that the best way to obtain such a statistical profile would be to issue a periodic timer interrupt, then you would simply need to monitor which what code was running when the interruption took place. This information is especially helpful to the programmers as it would allow them to optimize the specific sections of the code that are consuming the most CPU resources, and thus making the overall program more efficient.
Answer:C) Uninterruptible power supply
Explanation:Uninterruptible power supply(UPS) is the device that is used when the input source of power does not work or fails and thus it acts as a power supply in the emergency situation.This electronic devices in the protection of the hardware components of computer system etc.
Other option are incorrect because power strips, surge protector and password generator are no the devices that work during the power black out situation.Thus, the correct option is option(C).
Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
