Refraction represents a change in the direction of propagation when beams of light encounter a medium with a different density.
Reflection is the return of light to the medium it came from when it encounters a mirror.
Answer: Buffered
Explanation: Buffered memory is the memory contains registers between the modules of dynamic random access memory(DRAM).It is also known as registered memory. The purpose of using buffered memory to increase the stability and decrease the electrical load.
Other options are incorrect because ECC(error correcting code)memory is for correction and detection of incorrect data, non- parity memory is that don't utilize ECC module and multi-channel used for the increment in the rate of transmission between memory controller and DRAM.
Thus,the correct option is option buffered memory because of serial communication pattern with memory controller and parallel communication technique with chips .
A tool in administrative tools which you should open if you want to view messages to troubleshoot errors is an: b. event viewer.
<h3>What is an operating system?</h3>
An operating system (OS) can be defined as a system software that's usually pre-installed on a computing device by the manufacturers, so as to manage random access memory (RAM), software programs, computer hardware and all user processes.
<h3>What is an
event viewer?</h3>
An event viewer can be defined as an administrative tool that is found in all versions of Windows Operating System (OS) which is designed and developed to enable administrators and end users in viewing the event logs of software application and system messages such as errors on a local or remote machine.
In this context, we can reasonably infer and logically deduce that an event viewer is a tool in administrative tools which you should open if you want to view messages to troubleshoot errors.
