Q.
1.Amazon.com tries to fake strategic advantage of its resources. of what physical resources does Amazon.com take advantage?
A.
The physical resources does amazon.com take advantage is its simplicity of that help the clients to avoid the cost and time in establishing their own storage network,one that is distributed around the globe and on which data elements are replicated, so that if one server is down,another can still provide the data.
Q.
2. Does amazon.com strategically leverage anything else in addition to physical assets?
A.
Yes,
Q.
3.What are the benefits of S3 for small company?
A.
The benefits of S3 for small company is that the company had rapid growth but has limited staff and data-center space,can store vast amount of data that must be accessible from any part of the world, and it is reliable,
Q.
4. At the current rates for S3 services,Amazon.com does not make a great profit ( or any at all). Why, then, do you think Amazon.com offers S3?
A.
Amazon.com offers S3 because provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites.

Enterprise Mobile Computing:
A Case Study
Presentation Abstract The explosive growth and evolution of smart phones and other mobile computing devices is redefining the way businesses interact with their customers and employees. OCI will present a case study about a local service business that had outgrown its ability to effectively manage its mobile workforce via phone, FAX, and personal computer. In just a few weeks, OCI developed a native smart phone application and hosted web service to enable scheduling and dispatching of workers, communications with workers at remote sites, recording of vital information about work performed, and integration with existing business processes and data. The presentation will discus how this client leverages huge public/private investments in communications infrastructure, GPS, mapping and street navigation systems, hosted services, and an open mobile operating system, to completely transform itself. The case study will explore the salient business drivers, architectural objectives and constraints, applicable standards, technology, and platform choices, and application design and implementation considerations of the solution developed by OCI for the small business.

Mobile computing
Mobile computing
is a form of human–computer interaction by which a computer is expected to be transported during normal usage. Mobile computing has three aspects: mobile communication, mobile hardware, and mobile software. The first aspect addresses communication issues in ad-hoc and infrastructure networks as well as communication properties, protocols, data formats and concrete technologies. The second aspect is on the hardware, e.g., mobile devices or device components. The third aspect deals with the characteristics and requirements of mobile applications.
Limitations;
Insufficient bandwidth: Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA and HSUPA 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed wireless LANs are inexpensive but have very limited range.
Security standards: When working mobile one is dependent on public networks, requiring careful use of VPN. Security is a major concern while concerning the mobile computing standards on the fleet. One can easily attack the VPN for a very huge number of networks interconnected through the line.
Power consumption: When a power outlet or portable generator is not available, mobile computers must rely entirely on battery power. Combined with the compact size of many mobile devices, this often means unusually expensive batteries must be used to obtain the necessary battery life.
Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
Potential health hazards: More car accidents are related to drivers who communicate with mobile devices. Cell phones may interfere with sensitive medical devices. There are allegations that cell phone signals may cause health problems.[citation needed]
Human interface with device: Screens and keyboards tend to be small, which may make them hard to use. Alternate input methods such as speech or handwriting recognition require training

cs case study
How HCI (Human-Computer Interaction) relates to the following fields?
HCI relates in Psychology to understand the role of mental functions in each person and its social behavior, while it is also explore the underlying physiological and neurological processes.
HCI relates in Computer Science through the study of the theoretical foundations of information and computation, and their practical techniques for their implementation and application in computer systems.
HCI relates in Language of CS and linguistics concerned with the interactions between computers and human languages, By extension the term also refers to the type of thought process, which creates and uses language, and it is also essential to both meanings is the systematic creation, maintenance and use of systems of symbols, which dynamically reference concepts and assemble according to structured patterns to form expressions and communicate meaning.
HCI relates in Sociology in which an interdisciplinary field focused on the interactions between the users and computer systems, including the user interface and the underlying processes which produce the interactions, it is now on understanding that the relationships among users' goals and objectives, their personal capabilities, the social environment, and the designed artifacts with which they interact. human-computer interaction is also concerned with the development process used to create the interactive system and its value for the users.
HCI relates in Ethnography in which it is often employed for gathering empirical data on human societies/cultures. Data collection is also often done through participant observation, interviews, questionnaires, etc. Ethnography aims to describe the nature of those who are studied through writing in the same way.
HCI relates in semiotics and branding where in The organization as a whole is looked upon as an informal IS, where
the values, beliefs and behaviour of individuals are important. The informal layer aggregates
the formal layer, which is the way individual actions and business processes should be carried
out according to rules in the organisation. It is also a part of
the formal system that is automated.
HCI relates in Design where in each of us provides comprehensive, state-of-the-art coverage of the field, and provides principles and skills for designing any technology through the use of many interesting and state of the art examples.
HCI relates in Engineering which is a practical usability engineering process that can be incorporated into the software product development process to ensure the usability of interactive computer products is presented. It has also basic elements in the usability engineering model are empirical user testing and prototyping, combined with iterative design.
HCI relates in Ergonomics and human factors in which provides a theoretical perspective on human factors and ergonomics (HFE), defined as a unique and independent discipline that focuses on the nature of human-artefact interactions, viewed from the unified perspective of the science, engineering, design, technology. It include a variety of natural and artificial products, processes and living environments.

To the man i loved before who inspired me to wrote dz poem...."A broken Promise"
the first time i saw you,
i dont know why i hate you.
until time come i've got to know you,
and you've make me feel blue.
I remember the month of may,
when you said "i love you to me".
my heart jump with joy,
and couldnt find the words to say.
You've promise you'd never leave me,
'til i say "yes" to what you say.
you've prove your love to me,
and make me feel so lucky.
But unexpected test comes our way,
yet, i did my best for you to stay.
and now that your gone away,
i struggle to leave my life each day...
thank god for having my family w/me,
and making me feel so loved & lucky.
surrounding me when i need someone to lean on,
wipe my tears and encourage me to move on...

"to my beloved nanay edith"..i wrote this for you..
Since you'd give birth to me
You'd never fail to let me see,
how precious i am to you
and letting me feel special & love by you.
i witness how you struggle to raise me,
& making me feel so loved & lucky.
you may not perfect on others eyes,
but for me,you'd been greater than perfect ..
i promise to treasure the love you shared,
with confident that you'd been w/us forever..
Guiding me as i faced this life ahead of me,
and keeping me safe all the way..
i thank god for the short time we shared,
together with pain,joy and laughters.
i may not show how much i love you,
i hope you feel it as i grow up w/you.
may the lord prepare your place w/him,
& find happiness w/the angels above & have fun w/ them.
may you find rest w/him peacefully,
and whisper us about gods beautiful story...
i missed you nanay....i love you soooo.... muchhhhhhd...
