To save a gimp file in a different file format, which step would you start with? question 9 options: save save as save a copy export as question 10 (1 point) question 10 unsaved what is considered to be the building blocks of digital images? question 10 options: picas pixels points question 11 (1 point) question 11 unsaved which of these tools makes it easier to see and work with the details in an image? question 11 options: crop tool free select tool move tool zoom tool question 12 (1 point) question 12 unsaved match the following terms with their correct definition. question 12 options: the balance between image file size and image resolution. the number of pixels in a digital image. 1. resolution 2. image optimization question 13 (1 point) question 13 unsaved how do you measure the resolution of an image? question 13 options: dpi mpi ppi rpi question 14 (1 point) question 14 unsaved true or false. the more pixels in an image increases the resolution and makes the image appear smoother. question 14 options: true false question 15 (1 point) question 15 unsaved true or false. the more pixels an image has the larger the file size and the longer it will take to share with others over the internet. question 15 options: true false question 16 (1 point) question 16 unsaved true or false. to optimize an image for the internet, use the smallest number of pixels that still allows the image to look good for the audience. question 16 options: true false question 17 (1 point) question 17 unsaved true or false. you can learn the file size, pixel dimensions and resolution about your image in gimp by selecting image properties from the image menu. question 17 options: true false question 18 (1 point) question 18 unsaved which tool in gimp allows you to optimize an image for screen or for print? question 18 options: measure tool scale tool perspective tool alignment tool

Consider a slotted aloha system, where the time slot equals the fixed duration of each packet. assume that there are 4 stations a, b,c, d sharing the medium. (a) stations a, b,c, d receive one packet each from higher layers at times 1.3, 1.5, 2.6,5.7 respectively. show which transmissions take place when, according to the slottedaloha protocol; describe all transmissions until all four packets have been successful. when needed, each station has access to the following sequence of random number, provided by a random number generator and drawn uniformly between 0 and 1: (1) station a draws numbers: 0.31, 0.27, 0.78, 0.9, 0.9, 0.11, 0. (2) station b draws numbers: 0.45, 0.28, 0.11, 0.83, 0.37, 0.22, 0. (3)station c draws numbers: 0.1, 0.2, 0.3, 0.4, 0. (4) station d draws numbers: 0.36, 0.77, 0.9, 0.1, 0.1, 0.1, 0.1, 0. (b) in slotted aloha, a station transmits in each time slot with a given probability. what probabilities would you assign to each of the four stations so as to: (i) maximize the efficiency of the protocol? (ii) maximize fairness among the four stations? (c) will the efficiency increase or decrease if we modify slotted aloha as follows: (i) get rid of slots and allow stations to transmit immediately? (ii) implement carrier sensing? (iii) implement collision detection? (iv) implement collision avoidance?

1. which of the following statements are true about routers and routing on the internet. choose two answers. a. protocols ensure that a single path between two computers is established before sending packets over it. b. routers are hierarchical and the "root" router is responsible for communicating to sub-routers the best paths for them to route internet traffic. c. a packet traveling between two computers on the internet may be rerouted many times along the way or even lost or "dropped". d. routers act independently and route packets as they see fit.
