She should report it to the superviser
In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.
Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.
Relative performance between programmed I/O and DMA:
For determining the relative performance between programmed I/O and DMA, important factors are:
1. Size of data
2. Frequency of operations
In the case above, An example of SaaS (Software as a service) are DropBox, UserGuiding and Salesforce.
<h3>How does SaaS (Software as a service) impact organizational security posture?</h3>
Software-as-a-Service (SaaS) security posture management (SSPM) is known to be a kind of a group that is made up of an automated security tools that is used for tracking security threats in regards to SaaS applications.
<h3>What is organization level security in Salesforce?</h3>
The organizational level is known to be one that gives room for a person to decide if and from where a given users can be able to access the system.
Note that SaaS platforms is made up of software that is said to be available via third-party and they include BigCommerce, Salesforce and others.

Answer:
It can be repaired with disk utility / recovery algorithms
In UNIX it can be done by scanning
In FAT file scan the FAT looking for free entries
Explanation:
When the crash happens, it is not a problem for UNIX and FAT file system
It can be repaired with disk utility/recovery algorithms.
The recovery algorithm is a list of all blocks in all files and takes a compliment as new free file.
In UNIX scanning can be done at all I-nodes.
In FAT file problem cannot occur because there is no free list .If there was any problem than it would have to be done to recover it to scan the FAT looking for free entries.
The device that this network administrator is most likely installing in the infrastructure is a Network Attached Storage (NAS).
<h3>What is a
Network Attached Storage (
NAS)?</h3>
A Network Attached Storage (NAS) can be defined as a file-dedicated storage device that is designed and developed to enable multiple end users and other heterogeneous client devices to store, share and retrieve data anywhere from a centralized disk, especially through a network.
In this context, we can infer and logically conclude that a Network Attached Storage (NAS) is the device that this network administrator is most likely installing in the infrastructure because it doesn't require licensing and the data stored on it at the file level can be accessed anywhere.
