An M.2 key is a notch on the pin contact surface of an M.2 expansion card which prevents insertion into an incompatible socket. The M.2 key IDs include 12 available letters from A to M. These letters correspond to the locations of notched pins on the card's contact surface and designate which interface the card is compatible with. M.2 expansion cards that are used for solid-state storage applications have key IDs of B and M. The B-keyed M.2 SSD cards use 2 PCIe lanes (lower read/write speed), while M-keyed M.2 SSDs use 4 PCIe lanes (higher read/write speed). M.2 SSDs with 2 notches on the card's pin contact surface (B + M) increase the card's compatibility as they can be installed in either of the two types of expansion slots on the motherboard. A. True
B. False

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year.txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

You have inserted new slides based on a word outline. how do you format these new slides to match the powerpoint presentation formatting? a. select all slides in the presentation and click format on the home tab. b. select the new slides and click reset on the home tab. c. select all slides in the presentation and click reset on the home tab. d. select the new slides and click format on the home tab.

Many everyday occurrences can be represented as a binary bit. for example, a door is open or closed, the stove is on or off, and the fog is asleep or awake. could relationships be represented as a binary value? give example.
