VIEW OF MEMORY ALLOCATION AND MANAGEMENT IN COMPUTER SYSTEMScseij
In this paper I have described the memory management and allocation techniques in computer systems. The
purpose of writing this survey paper is to elaborate the concept of memory allocation and management in
computer systems because of the significance of memory component in computer system’s hardware. It is
apparent from the work of computer scientists that effective and efficient main memory management and
virtual memory management in computer systems improves the computer system’s performance by
increasing throughput and processor utilization and by decreasing the response time and turnaround time.
Firstly I have compared Uniprogramming system with Multiprogramming system. After comparison I found
that Multiprogramming systems are quite better than Uniprogramming systems from the point of view of
memory utilization. Also the functionality of operating system routines which are responsible for user’s
memory partitioning must be improved to get better system performance in Multiprogramming system .In
Uniprogramming system , the processor remains idle most of the time but dividing the memory into
partitions for holding multiple processes as in Multiprogramming system does not solve the problem of
idleness of a processor. Mostly all of the processes need I/O access, therefore processor also remain idle in
Multiprogramming system. We have also discussed resource memory in detail and compared fixed
partitioning with variable partitioning. After in depth study we found that variable partitioning is more
advantageous than fixed partitioning because reallocation of page frames is impossible in fixed

Disasters can strike at anytime
Having a plan and the tools in place to make it on your own for a period of time can be crucial
Three simple steps can help you prepare for the unexpected

1. Unit 3 – Personal Preparedness
Taken from Beach, M. (2010). Disaster preparedness and
management. Philadelphia, PA, F. A. Davis Co. unless
otherwise referenced.
2. Please notice this unit does not
follow the order in your text. Use
Chapter 4 of your text to prepare
for this Unit of the Course.
3. Unit 3 Objectives
Course Objective met in this Unit is: #4- Select the needed
resources for preparation of large-scale disasters at various
levels.
•Organize a Plan
•Explore Needs of Families (Medications, Disabilities, Pets)
•Consider Supplies, Storage, & Shelter
•Examine Health Risks Post-disaster
•Consider Survival Until Restoration is Accomplished
•Recall Nursing Implications
4. Personal Preparedness Plan
• Means being personally prepared for
one’s self.
• Will include those you live with.
• For at least 3 days without outside help.
5. Risk Assessment
Questions to ask:
• What puts your town at risk?
• What may happen to the structure you live
in?
• If you evacuate, where will you go?
• Where are the local shelters?
• What about temperature extremes?
6. Risk Assessment continued
• What about first aid needs?
• Are there family members that need special medications
or have disabilities that require special needs? Pets’
needs?
• What are our water, food & sanitation needs?
• Will your family be able to manage without your
presence?
• How will communication be handled?
7. Begin your own PPP
Make your plan with paper & pen – the only way
to really get started! The following are helpful
guides:
Text book

system.
http://www.dhs.gov/files/publications/ntas-public-
guide.shtm
• National Terrorism Advisory System
• NTAS Alerts
• The NTAS Alert – How can you help?
15. Health Risks Post Disaster
• Victims and health care workers will be exposed
to conditions outside of normal. These
conditions will vary based on the type of disaster
and its various components
• Alertness, awareness, calmness & a positive
attitude are essentials in survival.
(Veenema, 2007)
16. Nursing Implications
• Nurses can influence those in their sphere of
contacts & share their knowledge of
preparation with them.
• Nurses should use extra caution in caring for the
ill or injured, protecting themselves with PPE
at all times until the health hazards can be
identified. (Veenema, 2007)
