Suppose memory for the address space (process image) is allocated contiguously using dynamic memory allocation. What extra hardware is needed to generate a physical address and why? Solution Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Its function i to track whenever some memory gets freed or unallocated .It then updates the status.There are 2 ways dynamic and static. dynamic routines of the library are stored on a disk in relocatable form and are loaded into memory only when they are needed by the program.A reference to the dynamic module is not used to link the library with the program when dynamic linking is used. Dynamic Link Libraries (DLL) in Windows and Shared Objects in Unix are examples of dynamic libraries.memory pool allocation is used. virtual memory may also be used.The Translation Lookaside Buffer (TLB ) is the main component of the processor responsible for virtual-memory..

Memory management Assignment Help
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.

Solution
2. (a) Virtual Memory: In computing,virtual memoryis a memory management technique that is
implemented using both hardware and software. It mapsmemory addresses used by a program,
calledvirtual addresses, intophysical addressesin computer memory. Main storage as seen by a
process or task appears as a contiguous address space or collection of contiguous segments. The
operating system manages virtual address spaces and the assignment of real memory to virtual
memory. Address translation hardware in the CPU, often referred to as a memory management
unit orMMU, automatically translates virtual addresses to physical addresses. Software within
the operating system may extend these capabilities to provide a virtual address space that can
exceed the capacity of real memory and thus reference more memory than is physically present
in the computer.The primary benefits of virtual memory include freeing applications from having
to manage a shared memory space, increased security due to memory isolation, and being able to
conceptually use more memory than might be physically available, using the technique of
paging.
Virtual memory makes application programming easier by hiding fragmentation of physical
memory; by delegating to the kernel the burden of managing the memory hierarchy(eliminating
the need for the program to handle overlays explicitly); and, when each process is run in its own
dedicated address space, by obviating the need to relocate program code or to access memory
with relative addressing. Memory virtualization can be considered a generalization of the
concept of virtual memory.
Virtual memory is an integral part of a modern computer architecture; implementations require
hardware support, typically in the form of a memory management unit built into theCPU. While
not necessary, emulators and virtual machines can employ hardware support to increase
performance of their virtual memory implementations. Consequently, older operating systems,
such as those for the mainframes of the 1960s, and those for personal computers of the early to
mid-1980s (e.g. DOS), generally have no virtual memory functionality, though notable
exceptions for mainframes of the 1960s include:

Find all elements of our ring R that have norm 1. Show that no element has norm 2 or 3.
Solution
a) This element is clearly non-zero, and not a unit. If it is a product of two
non-units, then its norm is a product of two integers of absolute value greater than
1, a contradiction
b) for this we will assume that P is the principal
We need to show that
P s not principal, since
P^2= (2) (easy to check by direct
computation) its order in the class group divides 2, Now P has one generator , then the norm of
this generator is 2
so we can say in the equation it has no principal
it means if it has no principal with elements it has no norm
so we orove for 3 similarly.

At a sudden contraction in a pipe the diameter changes from D_1 to D_.pdf
At a sudden contraction in a pipe the diameter changes from D_1 to D_2. The pressure drop.
Delta p, which develops across the contraction is a function of D_1 and D_2. as well as the
velocity, V, in the larger pipe, and the fluid density, and viscosity, mu. Use Du K and n as
repeating variables to determine a suitable set of dimensionless parameters. Why would it be
incorrect to include the velocity in the smaller pipe as an additional variable?
Solution
Let DP= F(D1,d2,v,RHO,MU)
units dims pressure F/L^2
L
V =L/t
D = L
rho = FL^-4T^2
Mu= F L^-2T
First dimensionless group using D1 V mu are recurring variables
Pi1 = DelP * D1^a V^b MU^c
since this is non dim, obtains Pi1 = DELP *D1/(V*MU)
Similarly for P2: new entering variable D2, obtain D2/D1
Similarly Pi3, using rho as entering variable,
Pi3 = Rho*D1*V/Mu.

Solution
1.Now a days Internet offers extraordinary opportunities for \"speakers,\" broadly defined.
Political candidates, cultural critics, corporate gadflies -- anyone who wants to express an
opinion about anything -- can make their thoughts available to a world-wide audience far more
easily than has ever been possible before.
Mass Media (one to many): Similar to mass media (radio, television, print media),
Internet allows the broadcaster to reach a large audience. But, unlike mass media,
Internet enables any user to be a publisher or broadcaster since editorial control is
shifted from a small elite; editors and producers, to every user. Where mass media
represent a closed, edited, communication system, Internet holds an open, interactive
communication sphere where everyone can be both speaker and listener.

Why should anyone else care about what I do with my sewage on my own .pdf
Why should anyone else care about what I do with my sewage on my own property? Integrate
specific examples from course material in your response.
Solution
Anyone is going to care what you are going to do with house hold sewage generation and
disposal of sewage into the environment because sewage may causes high environmental
problem - climate change due to presence more non-degradable phosphorous & organic
compounds.
Human impacts on environmental change via sewage are leading to the following imbalance in
the ecosystem at trophic levels. Household-sewage and toxic lead pollutants are other factors
responsible for death of the photosynthetic microalgae & macroalgae result in dead zone with
photosynthetic biomass. This dead zone formation is mainly have higher impact on nitrogen
cycle level of water and nitrogen cycle is going to increase due to higher farm fertilizers mixing
into the aquatic zone via storm water finally bacterial activity is going to reduce “dissolved
oxygen level” available to the other aquatic species dramatically via aerobic respiration.

especially the production of IL-8, IL-12, IL-1, IL-6, and TNF-alpha?
What is the link between this and c-reactive protein levels in the blood stream?
Solution
The immune system is comprised of two branches: innate and acquired immunity. The innate
immune system is the first line of host defense against pathogens and is mediated by phagocytes
including macrophages and dendritic cells (DCs).
The innate immune response relies on recognition of evolutionarily conserved structures on
pathogens, termed pathogen-associated molecular patterns (PAMPs), through a limited number
of germ line-encoded pattern recognition receptors (PRRs), Upon PAMP recognition, PRRs
present at the cell surface or intracellularly signal to the host the presence of infection and trigger
proinflammatory and antimicrobial responses by activating a multitude of intracellular signaling
pathways, including adaptor molecules, kinases, and transcription factors. Several classes of
PRRs, including Toll-like receptors triggers functional maturation of dendritic cells and leads to
initiation of antigen-specific adaptive immune responses.
Macrophages activated at sites of tissue injury produce a number of cytokines into the
bloodstream, most notable of which are the interleukins IL-1, IL-6 and IL-8, and TNF-, which
induces hepatocytes to synthesize acute phase proteins (APP) including C- reactive protein. The
level of CRP in blood plasma can rise as high as 1000-fold with inflammation. Thus the greatly
raised level of c- reactive protein in the blood stream can be viewed as a strategy to overcome the
poplulation of pathogens..

What are two ways that meiosis could produce gametes that contain genetic material that is

What are two ways that meiosis could produce gametes that contain genetic material that is
different from the parent cell?
Solution
Answer:
The two ways that meiosis could produce gametes which differ genetically from its parent cells
are as under:
(1) During meiosis, homologous chromosomes undergo independent assortment. This means that
the chromosomes associate in no way with one another. Thus, the gametes so formed may have
any combination of paternal and maternal chromosomes.
(2) Crossing over results in the exchange of genetic material between homologous chromosomes,
resulting in recombinant chromosomes. It occurs during the pachytene stage of meiosis I. This
process gives rise to new recombinant varieties and thus the gamete so produced differ
genetically from the parentals..
what is the process in society that made this change to advertising .pdf

new level of diff
Solution
Over the years, the advertising objectives has changed with change in societal structure and its
morality. Advertising is a process to attract customer towards a product or service and it takes
the route to arouse various emotion of the target audience. As the societal value has changed
over the years, so has changed the pattern of advertisement to lure the consumer. In earlier days,
when advertisindg came into picture, the society used to be closely knitted and had joint families.
Hence, it was possible to capture a large audience at a go and that too with a well directed
common messaage that includes the societal value of being together. As time progressed,
families broken apart and nuclear families arose in the scene-so advertisers started targeting
individual people\'s choices and came up with 2-3 versions of a single advertisement that can
attract different customers having a same choice but with different mentality. Moreover, the
division of society into high income group, middle income group and lower income group made
the advertiser think in different ways.The concept of niche-advertising crept in- advertisers
started targeting people based on their income. Then came the era of internet that changed the
advertising objective all together. Initially the case was to attract the customer towards a product
now marketers try to present their product at a place and time when customers need it, Today
consumer is busy, having various options to compare - so reaching to the customer at a right time
and at a right place is very necessary-so came the practice of using direct mail communication,
tracking customer search history to know his/her preferences and present him/her with the exact
product they want, came the concept of testimony from satisfied customer to gain confidence of
other customers.
Qualitative changes over the years that represents a new level of difference:
- Niche advertising- Targeting preferences of individual class
- Personal Targeting through internet- helped to save conumer efforts and made the experience
rich..

Two cards are randomly selected from a 52-card deck. What is the pro.pdf
Two cards are randomly selected from a 52-card deck. What is the probability that the draw will
yield an ace and a face card?
Solution
There are 52C2 = 1326 ways to pick 2 cards in that order.
There are 4 ways to pcik an ace, and 12 ways to pick a face card. Those are 4*12 = 48 ways in
total.
Hence
P(ace and face) = 48/1326 = 0.036199095 [ANSWER].

Suppose memory for the address space (process image) is allocated co.pdf
- 1. Suppose memory for the address space (process image) is allocated contiguously using dynamic memory allocation. What extra hardware is needed to generate a physical address and why? Solution Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Its function i to track whenever some memory gets freed or unallocated .It then updates the status.There are 2 ways dynamic and static. dynamic routines of the library are stored on a disk in relocatable form and are loaded into memory only when they are needed by the program.A reference to the dynamic module is not used to link the library with the program when dynamic linking is used. Dynamic Link Libraries (DLL) in Windows and Shared Objects in Unix are examples of dynamic libraries.memory pool allocation is used. virtual memory may also be used.The Translation Lookaside Buffer (TLB ) is the main component of the processor responsible for virtual-memory.
