Which of the following best describes a situation where software should be upgraded instead of replaced? a three-year-old laptop was dropped, the screen was cracked, and it doesn’t turn on anymore. a one-year-old budget computer could be upgraded to an entertainment computer for 75% of the price of a new one. a six-year-old computer needs a new cpu to run the latest video production software. a six-month-old computer would run new database software faster with more ram installed.

Consider how gaming consoles initially relied on joysticks and joypads and then made the switch to modern gaming controls, which include analog sticks, buttons and switches, touch controls, accelerometers, motion controls, etc. name at least two kinds of gaming experiences that are possible with these new control devices but were not possible on original joysticks. explain how new technologies made this newer game style possible.

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
