The correct answer is option D, the last one! <3
Answer:
Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
A CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing basic arithmetic logical, control and input/output operations specified by the instructions.
Knowing this, the answer is both C - That it coordinates the flow of instructions and data within computers, And A - That a control unit performs arithmetical and logical computations.
If you can only select one answer, I'd personally go with A.
I'd say B: the amount and type of security placed on an application.
This is a common problem that exists between IT and other user departments. The IT department is well known for closing up certain sites and applications needed by other departments all in the name of security. As a result, it might slow down operations within different department and may cause inefficiency.
