What is the total capacity of this disk?




1. A multiplattered hard disk is divided into 1100 sectors and 40,000 cylinders. There are six platter surfaces. Each block holds 512 bytes. The disk is rotating at a rate of 4800 rpm. The disk has an average seek time of 12 msec.;a. What is the total capacity of this disk?;b. What is the disk transfer rate in bytes per second?;c. What are the minimum and maximum latency times for this disk? What is the average latency time for this disk?;2. A typical published page consists of approximately forty lines at seventy-five characters per line. How many published pages of 16-bit Unicode text would fit on a typical 600MB CD-ROM? How many published pages of text would fit on a netbook computer with an 80 GB flash memory?;3. A high-quality photographic image requires 3 bytes per pixel to produce sixteen million shades of color.;a. How large a video memory is required to store a 640 ? 480 image during display? A 1600 ? 900 image? A 1440 ? 1080 image?;b. How many 1024 ? 768 non-compressed color images will fit on 4.7 GB DVD-ROM?;4. For a motion picture image it may be necessary to change every pixel in the image as many as thirty times per second, although usually the amount of change is somewhat smaller. This means that without data compression or other tricks that a large number of pixel values must be moved from main memory to video memory each second to produce moving video images. Assume a video image on the screen of 1 1/2 ? 2, with a pixel resolution of seventy-two dots per inch and a frame rate of thirty per second. Calculate the required data transfer rate necessary to produce the movie on the screen. Do the same for an image of 3 ? 4.;5. In printer jargon, ??replaceables?? are the items that are used up as part of the printing process.What are the replaceables in a laser printer? In an inkjet printer? In a dot-matrix impact printer?;6. Explain the difference between pixel graphics and object graphics, and discuss the advantages and disadvantages of each.;Chapter 10 in attachment;Attachment Preview;The_Architecture_of_Computer_Hardware_Systems_Software__Networking_An_Information_Technology_Approach_4th_ed_I._Englander_Wiley_2009_BBS.pdf Download Attachment;Additional Requirements;Level of Detail: Show all work
