- Are you in agreement with the statement that "there is no idea of client and server sides of a communication session" while using an application that facilitates peer-to-peer file sharing? There are both positive and negative reasons for doing this.1) Write a bash script to count the number of files in a directory and all the subdirectories.Here is an example of a page that has encountered an error. On what portion of the OS do they rely? The most fundamental question is, what does this blunder entail?
- The If-Modified-Since header can be used to check whether a cached page is still valid. Requests can be made for pages containing images, sound, video, and so on, as well as HTML. Do you think the effectiveness of this technique is better or worse for JPEG images as compared to HTML?This header may be used to determine if a cached page has been modified since it was last accessed. Requests may be made for pages that include pictures, sound, video, and other types of media, in addition to HTML. Do you believe that the efficacy of this approach is greater or worse when used to JPEG pictures as opposed to HTML code? Consider the definition of "efficacy" carefully, and then provide an explanation for your choice.To implement LRU, each page uses a referenced bit. If we wanted to implementa least frequently used (LFU) page removal algorithm, where the least-usedpage would be removed from memory. what would we need to add to thetables? What software modifications would have to be made in order tosupport this new algorithm?
- GFS snapshots enable nearly instantaneous copies of huge files or entire directory structures. How does GFS do this quickly? a) By acknowledging the request immediately and performing the copies in the background. b) By pipelining writes through multiple chunkservers at once. c) By storing all the data in memory. d) By having multiple files point to the same set of chunks until one of the files gets modified.33 In Ms-Word, which of the following is not a type of page margin? Select one: a. Center b. Left c. Right d. TopSending a large file requires the usage of cypher block chaining or cypher feedback mode. How much more efficient is one?
