You are the system administrator for a multi-user operating system, and users have reported performance issues, particularly slow system response times. Affer investigation, you suspect memory management issues. Explain the concept of memory management in operating systems, how it affects system performance, and identify potential canses of slow system response times related to memory. Discuss strategies and mechanisms that ean be employed to optimize memory management and improwe system performanoe in this scenario. Question \#7 Concurrency You are a sottware developer responsible for designing a real-time monitoring application that collects and processes data from nualtiple sensors simultaneously. The application must efficiently manage coocurency to ensure that sensor data is processed in real-time. According to the given below scenario in which concurrency issaes can affoet the real-time data processing. Explain in detail the key considerations and synchronization mechanisms that can be employed to address concurrency challenges and meet the real-time requirements. Scenario: Imagine a scenario where the application teceives data from various sensors monitoring crifical infrastructure, such as a power grid. The sensors send data at different intervals and coocurrently. The application most process this data in real-time and raise alerts of take corrective actions based on the received data. Question 48 Disk Scheduling You are the wystem administrator for a file server that stores and serves large volumes of datn to users. Users have cocnplained about slow flle acsess times, particularly during peak usage hours. Explain the coesept of divk sheduling in eprating systems and hew if inpacts file access times. Identify potential causes of slow file access times related to disk sheduling and discuss strateges and mechanisms that can be employed to optimine disk scheduling and improve file access performance in this scenario
