Answer:
SuperFetch
Explanation:
Superfetch is a memory management technique on windows service that enables or fetch frequently use applications on systems and launch them faster because the frequently use applications has been preload into the system memory for easy access when they want to be used.

One of the most important part of Superfetch is that it saves alot of time because you don't have to search the applications before you get access to them in as far as the application was frequently used.
Answer:
a. 2^6, or 64 opcodes.
b. 2^5, or 32 registers.
c. 2^16, or 0 to 65536.
d. -32768 to 32768.
Explanation:
a. Following that the opcode is 6 bits, it is generally known that the maximum number of opcodes should be 2^6, or 64 opcodes.
b. Now, since the size of the register field is 5 bits, we know that 2^5 registers can be accessed, or 32 registers.
c. Unsigned immediate operand applies to the plus/minus sign of the number. Since unsigned numbers are always positive, the range is from 0 to 2^16, or 0 to 65536.
d. Considering that the signed operands can be negative, they need a 16'th bit for the sign and 15 bits for the number. This means there are 2 * (2^15) numbers, or 2^16. However, the numbers range from -32768 to 32768.
