Answer:

True

Explanation:

Semaphores are variables of abstract data types in programming used to control or restrict access to resources by multiple concurrent processes to avoid system failure like race conditions, by evaluating the available resources. There are various types of semaphores like the binary and counting semaphores which is used to lock and count resources respectively.

In C, the semaphore used to clean up the IPU objects is the WRITE_SEM.

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a
ANTONII [103]

Answer:

a) the average CPI for machine M1 = 1.6

the average CPI for machine M2 = 2.5

b) M1 implementation is faster.

c) the clock cycles required for both processors.52.6*10^6.

Explanation:

(a)

The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4

= 1.6

The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4

= 2.5

(b)

The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6

Given 80MHz = 80 * 10^6

The average MIPS ratings for M1 = 80 x 10^6  / 1.6 x 10^6

= 50

Given 100MHz = 100 * 10^6

The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6

= 40

c)

Machine M2 has a smaller MIPS rating

Changing instruction set A from 2 to 1

The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)

and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.

Difference between Computer safety practices and precautions
nika2105 [10]

Answer: This is a partial list of basic safety precautions to use when working on a computer: Remove your watch and jewelry and secure loose clothing. Turn off the power and unplug equipment before performing service. Cover sharp edges inside the computer case with tape. Never open a power supply or a CRT monitor.

Make sure the space underneath your desk is free from clutter and your legs have room to move. Use your mouse as close to the keyboard as possible. Adopt good posture while at the computer. Know how to adjust your chair to the most comfortable position.
