To manage the computer memory by controlling and coordinating act as memory management. It has resides hardware component, operating system and other applications. Hardware requires according to system requirement such as RAM, chips and hard disks. Operating system such as processor. Programmer does not know where request is gone all the work done by memory management it is in-built functionality. Memory requires two types of logical and physical. In logical part internal allocation of memory has been done. In physical part, hardware must satisfy the external requirement. It manages the process of allocating memory during runtime. Memory management does two task such as when a program needs a block a memory this would be managed by memory management and assigns the memory another one is when a program no longer needed that is deleted or deallocate by memory management. Main objective of it’s run time mapping from virtual to physical addresses.

Unit 5: Discussion - Technology Ethics The textbook, \"Technology in Action\", states: \"Because technology moves faster than rules can be formulated to govern it, how technology is used is often left up to the individual and the guidance of his or her personal ethics. Ethical considerations are never clear-cut. Theyâ€˜re complex and reasonable people can have different, yet equally valid views.\" What, in your opinion are some examples of how technology is being used unethically? What are some examples of how technology can support ethical behavior? What ethical behaviors do you think are most often ignored by people when using technology? Course: Intro to Computer (CS140) ***PLEASE CITE ANY AND ALL REFERENCES*** Solution Technology is never developed according to ethics rather it was developed according to the need and the intention for which it is made off. technology is developed by a group of person who belongs to some community or may be from different community Each and every community has a different ehtical value and prosperity so it is quite obvious that technology is being used unethically, becasue as said earlier technology is developed according to the need Ethical behavior has become even more unclear than before thanks to technology. Having a code of conduct. Technology is used unethically as human communication over internet allowing people to bully online. Some technology can be use to hack information etc Technology helps to have a code of conduct, resove conflits between and many more like this Ignored ethical behaviours Acceptable behaviour, accepting the user polocies, privacy of any user of that technology and many more .

Two parallel plates are seperated by a distance 2H. The plates are moved in opposite directions with constant velocity U0. Each Plate is maintained at uniform temperature T0. Taking into consideration dissipation , determine the heat flux at the plates. Assume Laminar flow and neglect gravity effect. Solution lets start the discussion by assuming e1 and e2 as absorptivities and E1 and E2 as emmisive powers of the plates,and also surfaces to be be diffuse and the parallel plates are infinittely long as no information is provided about their lengths.Also consider the space between plates is vaccum. At surface 1 E1=e1*sigma*T^4 surface 2 E2=e2*sigma*T^4 Now of flux E2 a fraction e1*E2 will be absorbed by surface 1 and rest (1-e1)*E2 will be diffused to surface 2.in the same sense of above e2*(1-e1)*E2 will be reflected on surface towards surface 1. hence net radiant heat flux leaving surface 2 is=E2 - e2(1-e1)E2 - e2(1-e2)*(1-e1)^2 ......... on summing up geometric series =E2[e1 / (e1 + e2 -e1*e2)] similarly radiant heat flux on surface 2 from surface 1 is =E1 [e2 / (e1 + e2 - e1*e2)] The above solving is for constant distance Now considering our moving plates issue solid angle is given by = Area / D^2 where D is distance between plates whic is D=2H+U(0)*t But E=integration(i(n)*d(solid angle)) just substituting this expression in above solved method we will get the required solution .

Typing Answer is Mandatory! Explain the difference between cyclic hydrocarbons, aliphatic compounds, and aromatic compounds. Solution ALIPHATIC COMPOUNDS Compounds whose carbon atoms are linked in open chains, either straight or branched, rather than containing a benzene ring. Alkanes, alkenes, and alkynes are aliphatic compounds. For example methane, propane AROMATIC COMPOUND: Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single an double bonds. when they follow huckle rule they are called aromatic thisÂ Â rule states that if a cyclic, planar molecule has 4n+2 ? electrons, it is considered aromatic. For example benzene, toluene CYCLIC HYDROCARBONS cyclic compounds are formed when carbon atoms bond together to form ring like structures. All the carbon carbon bonds are single bonds unlike aromatic compounds. For example cyclohexane. .

type of accounts Solution Solution: 1. All of the three are types of Accounts Receivable Uncollectible methods i.e. 2. To arrive at an accurate balance in Bank reconciliation statement, deposits in transit should be subtracted in book . Example - Book balance after deposit of $ 5,000 - $ 10,000 Bank balance during deposit in transit - $ 5,000. In order to match the balance, $ 10,000 - $ 5,000 = $ 5,000 3.To arrive at an accurate balance in Bank reconciliation statement, the service charged should be subtracted or debited from the cash book. Example - Suppose service charged by the bank is $ 50, already subtracted, in order to meet tha balance, this should be subracted from cash book as well. 4. Double declining method and written down value method ignore salvage value of the asset. 5. Current assets can be defined as the assets which held to be sold within in a period od 12 months. Assets which are held for more than 12 months are non-current assets. Further, current assets are either cash or cash equivalents which can be converted into cash within one year or 12 months. .

Two KPMG auditors, Kevin Hall and Rosemary Meyer, were accused of improper professional conduct in the audit of the financial statements of USFoodservice, a distribution company. US Foodservice in?ated the revenue reported by the company by recognizing income from ?ctitious promotional allowances or recognizing the promotional allowance early. The two KPMGauditors identi?ed valuation, existence, and completeness of the promotional income and receivable as a signi?cant audit area. During the audit, they found numerous cases where the company recognized promotional income when they should not have. In vouching vendor payments received by the company, the auditor discovered that the company had recognized signi?cant unearned prepayments of promotional allowances as income. The working papers show that the auditors identi?ed the revenue recognition attached to these prepayments as audit adjustments, but the adjustments were subsequently removed by liquid white-out. The very existence of the prepayments in the vendor payment ?le contradicted management Solution 1)a)The auditor must state in the auditor\'s report whether the financial statements are presented in accordance with generally accepted accounting principle. b)The auditor must obtain a sufficient understanding of the entity and its environment, including its internal control, to assess the risk of material misstatement of the financial statements whether due to error or fraud, and to design the nature, timing, and extent of further audit procedures. c) The auditor determines that informative disclosures are not reasonably adequate, the auditor must so state in the auditor\'s report. In this case, all three points are ignored. 2)No, the auditor not meet the requirements because auditor have improfessional conduct on his report. 3)Auditor failed to do proper Standards of Field Work as well as Standards of Reporting. .

Question 19 of 20 5 0 Points A important part of weather science is \"hot air rises\". This is an example of A. conduction B. convection C. radiation es Previous Save F5 FO F F4 F3 F1 F2 Esc Solution \'Hot air rises\' is an example of Convection . It takes place due to bulk motion of molecules within a fluid. Gases and liquid can both be considered fluids. Convection occurs naturally on earth as fluid motion takes places due to differences in density occuring because of change in the temperature gradient. A rise in temperature reduces the density of a fluid and causes it to float over the regions of high density and creates a gap. This gap is filled with surrounding cooler air which rises up again due to heat. This sets up convection current and forms the basis for weather patterns, sea breezes etc Radiation is heat transfer by electromagnetic waves at the speed of light. A hot object radiates heat in the form of waves and it does not require any material medium for propogation. Example for radiation is the Sun\'s energy reaching earth through space which basically is Space (vacuum) having no medium while earth\'s atmosphere consists of air (a composition of gases). .
