After making some wise short-term investments at a racetrack, Chris Low had some additional cash to invest in a business. The most promising opportunity at the time was in building supplies, so Low bought a business that specialized in sales of one size of nail. The annual volume of nails was 2,000 kegs, and they were sold to retail customers in an even flow. Low was uncertain how many nails to order at any time.

An apartment block has seventy units of accommodation. It is estimated that it is possible to let them all if the rent is $2,000 per month, and for each $100 per month the rent is increased there would be one unit vacant. LG, the manager of the block, finds that a vacant unit costs $100 per month to maintain whereas an occupied one costs $300. a. If profit from the lettings is measured as revenue minus maintenance costs, find an expression for profit in terms of the number of units let. b. What rent should LG charge to maximize profit? c. KA, a contractor, offers to be responsible for the maintenance of the entire block at a rate of $150 per unit, whether the units are occupied or….

A major federal intelligence agency has tasked your computer forensics team with performing a remote acquisition, required to do real-time forensics analysis of a possible terrorist cell operating at one of their satellite offices.

A major federal intelligence agency has tasked your computer forensics team with performing a remote acquisition, required to do real-time forensics analysis of a possible terrorist cell operating at one of their satellite offices.

The intelligence agency does not want the suspects to be aware of the ongoing investigation, so you are to identify in the presentation how the investigator will acquire the remote suspect without compromising the investigation. In addition, identify the real-time forensics procedures and actual tools (e.g., Encase Enterprise) used for computer imaging, image verification, and authentication over the network. Before performing the real-time forensics activity, the intelligence lead would like a presentation on how the forensics team will execute this investigation.

Assignment Guidelines

Provide the forensic real-time acquisition strategy in a presentation so the….

A two-level memory system has eight virtual pages on a disk to be mapped into four page frames {PFs) in the main memory. A certain program generated the following page trace:

(a) Show the successive virtual pages residing in the four page frames with respect to the above page trace using the LRU replacement policy. Compute the hit ratio in the main memory. assume the PFs are initially empty.

(b) Repeat part (a) for the circular FIFO page replacement policy. Compute the hit ratio in the main memory

(c) Compare the hit ratio in parts (a) and (b) and comment on the effectiveness of using the circular FIFO policy to approximate the LRU policy with respect to dais particular page trace.
