You are describing the boot process to a friend and get to the step where the device loads the operating files into RAM, including the kernel. Your friend starts to laugh because she was not aware that there were kernels in her computer. What do you tell her? A. The kernel triggers a series of steps and checks as the computer loads the operating system.

B. The kernel executes a series of test to check the components and identifies connected devices and checks their settings.

C. The kernel is a temporary storage area designed to help speed up processing time.

D. The kernel is the core of an operating system that manages memory, runs programs, and assigns resources.

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e. g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?
