Consider a banking systems that has 4000 ATMs situated across many places in a particular region. The bank customer can carry out many transactions like balance check, money withdrawal and deposit, password reset. These transactions takes 4, 8 and 6 bytes respectively. Each of this transaction has a timestamp attached to it which takes 8 bytes. This transaction data needs to be stored at different places like at ATMs, at an immediate buffer at streaming system side and in a persistent storage. Narrate the three use-cases which require the data to be stored at these three places and estimate the sizing required for the same and suitable option for the storage

Consider user accounts on a computer system with a Web server configured to provide user Web areas. In general, this uses a standard directory name, such as “public_html,” in a user’s home directory. However, access control needs to be properly set to allow users (with or without user accounts on the system) to browse the webpages. Assuming there are one main page (index.html), two pictures files (a.jpg and b.jpg) stored in an sub-directory (Image) and one pdf file (c.pdf) stored in an sub-directory (Doc), all under the public_html. Specify the access control for each directory and files that allows everyone to view the webpage.

For example, Computer A can communicate with computer C by using TELNET. At the same time, computer A communicates with computer B by using the File Transfer Protocol (FTP). For these processes to receive data simultaneously, we need a method to label the different processes. Could you explain that method?
TELNET, for example, allows Computer A to interact with Computer C. At the same time, computer A and computer B interact using the File Transfer Protocol (FTP). We need a mechanism to designate the various processes so that they may get data at the same time. Could you describe how you came up with that method?
For an old computing system with 2K bytes physical memory, and the virtual address has 13bits. Suppose that the size of page/frame is 256 bytes. For a process A, it has its codes and data inpage 0, 1, 2, 10, 11, 28, 29, where pages 0, 1, 10, 29 are in frame 1, 3, 4 and 6, respectively.Moreover, frame 0 contains kernel OS code/data and all other frames are free.a. Show the page table and the content of each PTE for process A;b. Use a figure to illustrate the address translation for virtual address 1110000100000 and explainwhat happens during the translation (interaction among page table, physical memory, disk, andoperating system);c. Suppose that there is a TLB with 4 entries and the current content has the mapping informationfor pages 0, 1. Draw a new figure to illustrate the translation of address 101000011000 andexplain what happens during the translation process.
We use the concept "paging" to map logical address to physical address. If the process size is 9216 bytes, the page size is 2048 bytes, how many frames should be allocated to this process? Do we have fragment? If so, please indicate the size of fragment?
Suppose there are four processes (P1 - P4) with respective arrival times of 0, 10, 30, and 40, and burst times of 30, 20, 50, and 20 ms. These processes are scheduled from a ready queue on first come first served. The average waiting time is?
How do dependability and availability relate to one another in the setting of a computer network? It's no longer relevant due to the aforementioned drawbacks. Is this long conversation really required?
Consider a file system that uses indexed allocation with a maximum of one index node per file. Suppose the index node occupies 4096 bytes, that each block pointer occupies 4 bytes. Ignore the metadata associated with the file that is usually contained in the index node. How large should a block be (in bytes) so that this scheme is able to completely access files on a 1 GB file system?
The physical platforms can be organized in different ways. For example, we canhave an Ethernet LAN that has a single coaxial cable shared by all nodes, or a hubconnecting the nodes with twisted pair cables into a star-like network. Moreover, thenumber of nodes and their capabilities can also vary from LAN to LAN. If we wantto run a massive networked application over a diverse set of physical platforms, wehave to implement a workload balancing mechanism to the logical platform to makeit more dynamic.How can we make communication, data, and control architectures more dynamic inthe following cases? Approach the problem from the point of view of roles, responsibilities, and functionalities and consider how they are interconnected.(a) Dynamic communication: If we have a server-network on a LAN, how can weincrease and decrease the number of servers on the fly without informing thischange to the clients?(b) Dynamic data: Suppose the data is distributed among the nodes on a WANand we want to…

Scheme that causes the most faults: a) First in First out b) LRU and FIFO are the same number of faults c) FIFO and Opitimal are the same number of faults d) All have the same number of faults e) Least Recently Used f) No faults occurs g) LRU and Optimal are the same number of faults h) Optimal NUMBER OF FAULTS CAUSED: a)
A given process has a page table as shown below. Assume that the page size is 2048 and that all the pages are in main memory. What do the numbers 3, 2, 6, 7, and 11 represent? Be specific. To which logical address will the physical address 7356 correspond? To which physical address will the logical address (3,420) correspond?
