Here's a C code snippet: #include <stdio.h> int main() { int year; printf("enter year:"); scanf("%d",&year); if(year>=2101) { printf("Distant future"); } else if(year>=2001&&year<=2100) { printf("21st century"); } else if(year>=1901&&year<=2000) { printf("20th century"); } else if(year<=1900) { printf("Long ago"); } return 0;} Output: enter year:2018 21st century.
</stdio.h>
Response:
a. Current disks do not reveal the actual locations of logical blocks.
Clarification:
Modern disks incorporate scheduling algorithms within the disk drive itself. This presents challenges for operating systems trying to optimize rotational latency. All scheduling methods end up having to perform similarly due to potential constraints faced by the operating system. Disks are typically accessed in physical blocks. Modern technology applies more electronic control to the disk.
Response:
d. RAID 6
Clarification:
RAID is a technological method for data storage that integrates several physical hard drive components into a unified logical structure. Its primary purpose is to ensure both performance and data redundancy.
RAID 0 is focused on data striping, but it lacks redundancy.
RAID 1 enhances performance to nearly double but restricts disk space usage to around 50%.
RAID 5 offers both redundancy and improved performance, though it is constrained by smaller drive sizes.
RAID 6 provides redundancy as well but with a decrease in performance.
RAID 10 boosts both performance and data security.
Hence, RAID 6 is the optimal choice that emphasizes redundancy at the cost of speed.
Answer: Sole Proprietorship. This question seeks to identify the business type mentioned in the scenario. In a Sole Proprietorship, the owner effectively is the business, managing all elements from operations to finance. Typically, this is the initial business form in entrepreneurship. The description fits Doug well; he operates the farming business independently, taking care of all its functions. Thus, it qualifies as a sole proprietorship.
The correct answer is C, MRI, I hope this assists!
