test 2 esei,,8sept09,,question2

the process of developing a new system will have to follow a strict order of a cycle called the system development cycle.there are five phases in how to develop a new system.first, planning the proposal.we need to plan first what is the users' requirement, the feasibility of the system will be tested and the products want to be developed.the right proposal can build a good system.

for the second phase is analyzing.we have to analyze the proposal or plan that we have made.the system will be analyzed whether it is useful or not.this is to avoid the system from having any problem.

and the third one is designing.after analyzing the system, we can design the system according to the suitability of system.this will make the user to recognize the system easily.

then for the fourth phase is implementation.for the implementation phase, they will install and try the new programs.this program is also will train the users when using it.then they can develop into the new program.

for the last one is operating,supporting and security.the system will be operated and supported by any other programs so that they can be used.then, the system will be included with security so that the users can use it safely.

test 2 esei,,8sept09,,question1

feasibility means measure of how suitable system development will be to the company.there are four tests to evaluate feasibility which is operational feasibility,schedule feasibility,technical feasibility and economic feasibility which is also called cost or benefit feasibility.

the final activity in the implementation phase is to convert the old system to the new one.this change can take place using one or more conversion strategies.first is direct conversion.this conversion change the old system to the new system alternating.so this will be no confusion for the users to convert it.the other conversion is parallel conversion.this conversion is using both of old and new system in the same time.this make the users can make check and balance.for the phased conversion it is using one system in one time.for this the feasibility has not been tested.and the last conversion is called pilot conversion.in this conversion they use both of the system differently.for the users they cannot identified which is the best system.between all of the conversion strategies,whether it is good or not it is in the users' choice to choose the best one.

n da last chapter!12!!

what is enterprise computing?

enterprise means large organization such as multinational corporation,university,hospital,research laboratory, or government organization.meanwhile enterprise computing, meaning that use of computers in networks that encompass variety of operating systems,protocols and network architectures.this chapter tells us what is the purpose of enterprise computing and the uses.

we can know more about the technologies,e-commerce,computer hardware and many more that related to this enterprise.moreover we also can know how to make computer backup to save our important files to be lost.so that we do not have to worry about it anymore.there are also the ways how to recover disasters if this happen.

information system,development and programming languages

information system means that a set of components that interact to achieve common goal.for businesses use many types of systems.there are 5 phases of system development cycle which is planning,analysing,design,implementation and operating,support and security.to develop the system we have to follow these phases one by one in order.so that there will no problem in developing new system.

there are 2 level of programming languages which is low-level languages and procedural languages.we can identify and differentiate between them.we can also develop web page.mostly for big companies.

b0ut chapter 10

in this chapter i learn about computer security,ethics and privacy.

this chapter shows that how we can protect our computer from viruses,worms,Trojan horses,bot nets,denial of service attacks,back doors and spoofing.Spoofing means that someone can duplicate anyone else ID.this have to be stopped before they can intrude computer's privacy.so there are so many ways we can prevent this thing.

another thing we should know in this chapter is how to prevent health-related disorders when using computers.there are some types of injuries causes by due to using computers too much.so it is important for us to know too.

reach @ chapter 9,,huhu...

what is database??well it is a collection of data organized so you can access, retrieve and use it...that is what i learn in this lesson,,database management...how to use it easily.to manage it we have to know bout their database software.there are some advantages of organizing the data in a database.so that the content in it do not be mess.but to organize it we have to know the methods for maintaining the high-quality data..

of course there were a lot of type of databases we should know..they have their own role to analyze and administrate the datas...

n0w in chapter 8,,,

n0w in chapter 8...the lesson is about communications and network...how they work through the world in universal way,,there are a lots of network too we can use and learn.this lesson also told us how the computers joint with another device into a various network.

there are also various communications devices, media and procedures we can learn in this chapter.this can lead us to know and connect with more people in the world.

chapter 7??

in chapter 7,,i learn that how the operating systems work and about the utility programs.there were so many various of stand-alone operating systems,,network operating systems and embedded operating systems...such as linux,,windows vista,,windows XP and many more...

each of them have their own functions and i only know the common functions.it also introduce several utility programs commonly found in operating systems.not only that..it also describe about several stand-alone utility programs.

then,,chapter 6....

i have learn b0ut how to store datas and instructions.how to differentiate various CDs and DVD formats.i alsoo can identify the uses of tape.those things are very useful to store important data in them.this can help me make my job in good condition.

so,,chapter 5 said....

input and output...
we can process and organize input and output device as we know how it works.i also know about the data and instructions more detail.there are a lots of methods of input and output.we can do more as we know them better.

chapter 4,, i think....

i think what i can get in this chapter is recognize profoundly about CPU.know more b0ut this thing,,i think it is important because i can know better what is its components inside it.

furthermore,,i also learn how the memory stores data, instructions and information.
the example of memory such as RAm,,r0m or cache....
those memory can save a lots of memory or data we want.they can save the work we had done so we do not lose our work at all.

not only that,,i also can c0mpare the various of the pers0nal computer on market today.i can choose the most better computer on my own to do my work.as i know some of those personal computer,,so it not so hard to choose the better one!

as i have my own personal computer i also can take care of it on my own as i also learn how to clean the system unit.this is so important so that i do not get much trouble when using it.that's all...

what can we say ab0ut chapter 3?

what can i conclude here is,,i learn h0w to rec0gnize the applications of software.h0w they work f0r human in daily life.there are a lots of software we can use.they have their own functions to help hard work to be simply work.this is very important for who want to do business..they really need this application so that their will be more easier and flexible.so that they can avoid any mistake in doing complex job.the business also can do well and everyone will satisfy with their work.

people also can do their work more better and efficiently done.so i think it is important for us to know more about this lesson.just for those who want to do their wide business in universal way.

next...chapter 2,,

in this chaPTer , it eXplains h0w t0 accEsS anD c0nNect t0 dA inTerNet.s0 that it can help me t0 surf internet easilY.i als0 LeaRn h0w t0 find dA inf0rmaTi0n in inTernET quicklY siNce i haVe t0 find a l0t of inf0rmati0ns f0r my assignmEnTs,oF c0urse!i als0 got t0 kn0w h0w t0 meet with pe0ple inside 0r outside country easily.with chatting ,we can always keep in t0uch wherever we are.i als0 can get so much friends as i want in instant messaging or e-mail.we can share our interest in any t0pics just in a computer.although our friends are far from us.buT in suRfiNg internet,there are also netiquette.i learn h0w t0 behave with people in internet or web s0 they can respect us t0o as well.we have t0 kn0w the limit t0 surf in internet.

what can i say,internet is also important for us in our daily life.but 0nly f0r d0ing c0mpuls0ry things n0t use it t0 harm anyone else.....

c0nclusi0n 4 chapTer 1,,

intr0ducti0n t0 c0mputers...

for this chapter,i learn that how to recognize the importance of computer literacy.i know that computers are now everywhere around us.i also got knowledge about computer and understand how to use it.computers are also have their own advantages and disadvantages.they have input process and output process.they also can store a lot of data,instructions and information for future use.there are two main components of motherboard which are processor and memory.i also learn about networks and internet in this subject.it is used to share and also save our time and money too.not only that,we also got to know about computer software which is a program that control and maintain the operations of the computer and its devices.so we can install anything in our computer.there are also a lot of types of computer such as laptop and pda today.this things can make our life more easier.

moreover,the computers also have the applications in society.they can help people in doing hard works such as in travel,health care,science and publishing and the most important i think in manufacturing.so that's all i can conclude for this chapter.
