If the floating-point number representation on a certain system has a sign bit, a 3-bit exponent and a 4-bit significand: What is the largest positive and the smallest positive number that can be stored on this system if the storage is normalized? (Assume no bits are implied, there is no biasing, exponents use two’s complement notation, and exponents of all zeros and all ones are allowed.)         What bias should be used in the exponent if we prefer all exponents to be non-negative?    

A task runs alone on a CPU. The task starts by running for 5 ms. The task then waits for 4 ms while the operating system runs some instructions to access disk. The CPU is then idle for 2 ms while waiting for data from disk. Finally, the task runs another 10 ms and completes. (2.5 points)   a. The elapsed time is ________________ ms.     b. The user CPU time is ________________ ms.     c. The CPU time is _____________ ms.     d. The system performance is _______________ ms.     e. The CPU performance is ______________ ms.

A victim’s estate filed a wrongful death action against a defendant, alleging that she murdered the victim. The victim was killed at 3:00pm, and the defendant has claimed that she could not have done it because she was at work when it happened. At trial, the victim’s estate called the defendant’s co-worker to the stand, expecting him to say that he noticed the defendant leave the office at 2:00pm on the day of the murder. However, on direct examination, the co- worker testified that he saw the defendant leave the office at around 4:00pm. After giving theco-worker the opportunity to explain or deny his statement made at his deposition that the defendant left the office at 2:00pm on the day of the murder, the victim’s estate seeks to introduce the deposition statement into evidence.  Is the co-worker’s statement from the deposition admissible?

Marge is setting up access controls for her company’s AWS infrastructure. She wants to ensure that Homer can only view specific S3 buckets, while Bart has full administrative rights to EC2 instances, and Lisa can only access billing information. Which AWS service would allow Marge to implement these different permission levels?

Nelson is evaluating two different IT infrastructure options for his business. Option A requires him to purchase and install equipment on his own premises, while Option B allows him to pay a cloud provider based on actual usage. Which statement best describes the key difference between these two approaches?

A polymer beam was designed to sit on three supports, but the middle support was accidentally placed 0.2 mm lower than the others. Determine the magnitude of the vertical reaction force at B after moment M = 0.80 N·m is applied and causes the beam to rest on all three supports. Let a = 50 mm, b = 50 mm, and EI = 0.85 N·m2. Assume that the supports allow rotation, no deflection at A and C, and no additional deflection at B.

A polymer beam was designed to sit on three supports, but the middle support was accidentally placed 0.4 mm lower than the others. Determine the magnitude of the vertical reaction force at B after moment M = 0.78 N·m is applied and causes the beam to rest on all three supports. Let a = 56 mm, b = 56 mm, and EI = 1.00 N·m2. Assume that the supports allow rotation, no deflection at A and C, and no additional deflection at B.
