What is the history of computer and how did computer generations develop?
The history of computers dates back to the 1800s with the invention of the first mechanical computers by pioneers such as Charles Babbage. However, the modern digital computer was not invented until the mid-20th century, with the development of the first electronic computers such as the ENIAC. Following this, computer generations developed, each characterized by a major breakthrough in technology, such as the use of integrated circuits in the third generation and the development of personal computers in the fourth generation.

After finishing the installation of Windows on a system with four physical hard disks, the installation process created system and C: volumes on the first disk (Disk 0) while the second disk (Disk 1) and third disk (Disk 2) were initialized without any volumes created. What are the expected statuses for Disk 1 and Disk 2?
Disk 1 and Disk 2 would have unallocated space.
Operating Systems Problem Four (15 points) Comparing page replacement algorithms Physical memory consists of 4 page frames, initially all empty. The following reference string is processed: 0 1 4 0 2 3 0 1 0 2 3 4 2 3 Show which pages are resident under the optimal page replacement algorithm. Indicate when page faults happen. Show which pages are resident under the FIFO page replacement algorithm. Indicate when page faults happen. Show which pages are resident under the LRU page replacement algorithm. Indicate when page faults happen. Problem Five (15 points) Comparing page replacement algorithms Physical memory consists of 4 page frames, initially all empty. The following reference string is processed: 0 1 4 0 2 3 0 1 0 2 3 4 2 3 Show which pages are resident under the second chance page replacement algorithm. Indicate when page faults occur. Assume that references to page 1 are write references (modifying page 1) and all others are read references. Show which pages are resident under the third chance page replacement algorithm. Indicate when page faults occur.
Optimal Order: 0 1 4 2 3, Page Faults: 9. FIFO Order: 0 1 4 2 3, Page Faults: 9. LRU Order: 0 1 4 2 3, Page Faults: 9. Second chance order: 0 1 4 2 3, Page Faults: 9. Third chance order: 0 1 4 2 3, Page Faults: 9.
