1. Technical documentation which is more or less used by the programmer for system maintenance.
2. User documentation.

What to include in the two documentations should be considered well in the documentation phase.

Next, it is implementation and real/live data testing phase. Please compare the different ways of the testing.

• Direct changeover
• phasing
• pilot running
• parallel running

The last phase is Evaluation/maintenance. When we evaluate a system, we have to evaluate it against the objectives set by us at the beginning of design. Limitation and necessary improvement should be further considered and evaluated.

Here is a more detailed introduction of flow chart.

When we are at analysis phase, we need to ask the following 3 questions:

• How is the job done at present?
• What are the problems with the current system?
• Can a new system solve the problems?

Information has to be collected. But how? What are the advantages and disadvantages of the different methods?

All the collected information should be recorded and collated.

Requirements specifications can then be developed. In other words, what exactly will the new system do? To answer the question, inputs, processing and outputs must be considered.

Next, we need to know how to make algorithm design, which is, to make a sequence of steps to complete a task.

• Internet security
• methods of system security
• data security

Viruses

• how viruses work
• virus prevention

Look here for more details.

• describe what hacking is
• describe what viruses are and how you can catch viruses

What are the advantages and disadvantages of a hospital control system? What is its impact on society?

What are the economic reasons for the use of computers?

What changes has the use brought in the working environment,employment? Please visit here to find out changes in work patterns.

Then, please read here for a short revision.

Miscellaneous areas such as education and training,entertainment:

• CAL
• Music
• computer graphics and animation

Please visit the sites and answer the question - What are the input, processing, output and storage for the following applications?

• a library system
• process control in industry
• payroll

And then, please visit the following links to have an idea of the usage of computer systems in real life:(this will be your homework: please write a summary for each application - how computing system is used? Due day: Friday)

• weather forecasting
• robotic and embedded control
• stock control and order processing
• booking system
• computer system in hospitals
• billing system

Most systems nowadays are able to send and receive messages to and from other computers. They are linked in a network, maybe to the internet. The following concepts were discussed today:

• modem,
• LAN and WAN

Homework for today: Please specify what e-commerce means and how it is used in our lives. Please also list the advantages using an electronic and video conferencing (using Skype, for example).  Due day: Wednesday (10/08).

A* to E means you have it. U means, try again...............but don't worry, you have a chance in a few months time. Take a break now and then get back on track and figure out a proper study programme for yourself.

In case anybody asks you, University of Cambridge tell us :

''IGCSE was created as a GCSE examination for international use and the academic demands (‘standards’) of IGCSE are equivalent to those of GCSE. IGCSE examinations are tailored for a multi–cultural, multi–lingual audience in a way that UK GCSE examinations are not. They are aligned to the standards of the UK GCSE, and equivalent on a subject–for–subject, grade–for–grade basis. ''

IGCSE A*-C is roughly equivalent to Cambridge Advanced ESOL or a 6.0 on the IELTS band.

Here is a link to Kuwait University : http://reg.kuniv.edu.kw/

The English language is like anything else: before you can convincingly break the rules, you first must know them..........who said that?

Why is IGCSE coming under so much criticism as of late ?

''Worries that tests are being "dumbed down" became so prevalent earlier this school year that an "independent watchdog", breaking from the qualifications and curriculum authority, was specifically commissioned to battle rumours of inadequacy and any truth behind them.

Headed by the education secretary, Ed Balls, the body was meant to ensure that exam standards were "robust" and that Great Britain did not fall behind "international competitors" in the business of producing bright young minds.

The main objection the dubious students have adopted is that the skills used in the exam are non-transferable; and I agree that these boys are unlikely to ever have a damsel rush up to them in a moment of urgency and ask them to examine the use of metaphor in Passage A.''

Seems like our IGCSEs are way ahead those  GCSEs kids................way ahead.They'd rather have all this project nonsense perhaps......

For some reason we, and others, had thought IGCSE was in some way easier than the GCSE ( an exam in English often  taken by ''foreigners''- it had to be ).Apparently the opposite is true. On a google search for ''what is the difference between IGCSE and GCSE'' the following came up:

http://www.guardian.co.uk/education/2006/sep/01/schools.uk1

''Independent school leaders today said it was "illogical" that the government did not recognise the International GCSE (IGCSE), widely seen as a more challenging qualification to the GCSE.

Ujian Matematika kemarin, sungguh-sungguh pengalaman pahit untuk saia. Terutama paper 2, padahal, saia suka matematika... [tapi boong', hhehehehe]. Mungkin terlalu tegang karena pertama kali ujian seperti itu tapi kayaknya ga mungkin deh, soalnya tangan gw ga gemetar tuh. Dan lagi, sempet-sempetnya gw menghibur diri.. Ingat banget tuh gw waktu 15 menit terakhir masih ada 3 soal yang masih kosong...

Uhh, perjuangan waktu itu...

"Waduh total skor soalnya 10 nih. Ya ampun, gw ga mau kehilangan poin 10 dari 70. Angka yang signifikan, gyaaaaaaaaaaaaa.." kata2 gw dalam hati, nyaris keluar dari mulut, apalagi kata yang terakhir.

"Ya, 15 menit lagi", kata Bu Rina

Gw semakin tegang, gw meyakinkan diri sendiri supaya bisa mengerjakan soal dengan baik.. Weee aduh gimana nih???

Dor~ Tiba-tiba gw dapet ilham, entah darimana.. yes.. gw nemu jawabannya...

2 lagi, bung...

ctakctikctukctakctikctuk... yesss, amen, 1 lagi selesai, aljabar, akhirnya.. terakhir...segitiga...

cosine rule, iya pake cosine rule, gw tahu pake rumus ini, tapi kok jawabannya gak ketemu2...

"1 menit lagi..." kata Bu Rina

AAAAAaaaaaaaaaaaaaaaaaaaaaaa, hell, gimana nih, cara di depan mata tapi kok jawaban tertutup kabut. huaaaaaaAAAAAAA...

Haduh2, dah stres dan saat gw sedang klimaks2nya...

YA AMPUN, GINI AJA GW LUPA??

Ternyata gw melupakan hal dasar dalam matematika, yah kayak pondasi buat bangun rumah gitu...

Pertambahan dan perkalian, menurut lo yang mana yang dikerjain dulu???

Perkalian kan? Ya, perkalian dikerjain duluan. Tapi kok dari tadi gw ngerjain tambah2an seh????

ctakctukctakctukctakctuk

Waktunya habis..

Hah??? Haduh gimana nih, masih ada satu soal lagi yang ga ada jawabannya, hiks, apes gw lolos lah satu soal.. sementara itu, waktu gw lihat ke depan,seorang teman gw, yang jenius, nama disamarkan, dengan muka santainya nyengar-nyengir, wah sialan ni orang, yang lain dah pasang muka stres juga, hu uh.

Sampe di rumah, gw nyoba soal tadi, dan ga nyampe 5 menit jawabannya ketemu, hiiiii sadis. Namun nasi sudah jadi defekasi apa boleh buat.Nah, terus waktu gw belajar paper4 buat berikutnya, barulah bokap gw menyadarkan gw kalo kalkulator gw modenya ada yang berubah, apa gitu dibilang papa. Namun,seperti yang udah gw bilang, nasi sudah menjadi defekasi, ternyata gw salah lagi karena gw ga cek kalkulator dulu sebelum ujian. Ya, ampun. Cukup sudah menyesal, tidak mau lagi mengulang kesalahan di paper4 dan untuk fisika.

Sudahlah, masi ada ujian di depan mata, yang non-subjek juga udah ngantri... hew3....

REGIONAL PROBLEMS:

UNEMPLOYMENT - those in the working population who are able and willing to get a job but cannot get a job. 
CONGESTION - overcrowding
INCOME INEQUALITY - large gap between the rich and poor

solutions:

UNEMPLOYMENT -

training and re-education 
government grants to start up firms
reduction in tax burdens
government spending in region on infrastructure - creates jobs (i.e. construction workers), attracts investment (from FDI, firms)  

CONGESTION-

make LABOUR more MOBILE
- training (occupational mobility) 
- government spending on roads, airports (geographical mobility)

INCOME INEQUALITY 

INCOME TAX - redistribution of income
^ progressive tax: proportion of income taxed rises as income rises. 
government spends revenue on welfare benefits. 

The alternating current in the primary coil, produces a changing magnetic field; this produces an alternating magnetic field around the secondary coil; which then induces a current.

• teach the rest how to write cohesive, sophisticated, dripping-with-rich-vocabulary-and-literary-devices, whilst avoiding embarrassing jokes that are funny only to Spanish people, yet crude and unamusing to native English speakers
• grade many practice essays (also for the Cambridge First Certificate)
• tomorrow night: party at the Embassy (what to wear?!?!)

• fix or replace my recently broken bed, thanks to whom i have had to sleep like a bat, with my head low to the ground and my feet levitated. the only potential upside to this (no pun intended) is the fact that the increased bloodflow to my brain could possibly help it perform better during the GREs.
• did i mention i had GREs this week?
