3. (8pts) The purpose of this problem is to interpret the specification information found on a computer Apple iPhone 8 - Specifications Width Height Thickness Weight Write a review Specifications Display Camera CPU BatterySAR Prices Dimensions: 67.3 x 138.4x 7.3 mm Weight: 148 g SoC: Apple A11 Bionic APL1W72 CPU: 2x Monsoon, 4x Mistral, 2100 MHz, Cores: 6 Cores: 3 RAM: 2 GB Storage: 64 GB, 256 GB Display: 4.7 in, IPS, 750 x 1334 pixels, 24 bit Battery: 1821 mAh, L-Hon OS ios 11 Camera: 4032 x 3024 pixels, 3840 x 2160 pixels, 60 fps SIM card: Nano SIM Wi-Fi a, b, g, n, n 5GHz, ac, Dual band, Wi-Fi Hotspot USB 2.0 Bluetooth: 5.0 Positioning: GPS, A-GPS, GLONASS, Wi-FI, Cell ID Prices Add for comparisonSuggest an edit Provide a few sentences of explanation for each item in the specification above. Just providing the words that the acronyms stand for is not sufficient. You will probably have to do some research, as the class notes did not cover all of these terms. a. b. The display type is often referred to as Retina HD display. Do some research to find out what this means Identify one upgrade to the iPhone 8 to make it more to your liking. Provide sufficient detail so someone could price shop for you. Finally, justify the upgrade (i.e., what will it do to make the machine "better"). c. IT101-Homework 2 4. (6pts) Use the specifications from the previous problem to answer the following questions. a. Assuming nothing is compressed, how many megabytes are required to hold the phone's display? Show your work to receive full credit How many times could you copy this information into RAM? There are two cameras. Pick one and show the storage size of a 30second video. b. c. 5. In your AFS file space, do the following: (2pts)Change the permissions on your home directory and the IT101 directory (see in class lab) so that I (UCID llw2) can list and read your files. In your homework WORD document, type the command you used to make this permission change. a. b. (2pts)In your under the "IT101" directory, make a new directory called "homework2" using mkdir (It should automatically inherit the permissions from your home directory if you did step Sa first otherwise you will need to change permissions manually on homwork2). In your homework WORD document, type the commands you used to show the afs and UNIX permissions for homework2 (4pts)Create a short text file containing your name and major. Name the file IT101-HW2.txt and place it in your homework2 directory. It is probably easiest to create the file on your usual computer and then use MobaXterm to transfer the file to AFS. Use notepad or wordpad, not Word, to create the file. c. d. (1pts)Use pwd to get the absolute path to directory homework2 Write the absolute path to directory homework2 into the WORD document you submit for this homework. I will grade this problem by trying to read your file, so double-check that the path is correct. 3.
