The structured approach to software development consists of the five steps: define the problem, plan the solution, build the solution, check the solution and modify the solution. The first stage focuses on defining the problem and lists the requirements of the software. In the second stage the data and processes of the existing system are analysed so that the development team know how the system works. Stage 3 involves building the solution. This is followed by the testing stage, after which the software is placed in operation. While in operation, there is a constant evaluation, the results of which are used to modify the program.

english ideas... from dylan's blog

1. Really technical sci-fi story, revolving around a society living in a Dyson Sphere-world, ie. an artificial sphere around a sun, with gravity generated by rotation around 3 axes. The society has been isolated and stagnant for so long, and would have lost much knowledge and has regressed from their scientific/technological pinnacle, and so much of the workiings, theories and ideas behind the functioning of their world would be incomprehensible to them. The story would be based on a malfunction in the sphere, causing "natural" disasters, which causes the keepers of knowledge, a group called (for now) the Aluminati Guild... <-- working label only, whose members have to travel around the world, and eventually stumble? upon an series of counter-rotating airlocks (3 to be exact, as there are three axes to counter-rotate against) and see the outside universe... and find maybe an dysfunctional-yet-sagelike master computer, and starts a revolution scientifically and technologically wise.

2. Possibly-epic story, set in the distant future. We have faster-than-light travel, but it is almost prohibitively high, with wormhole generators needing to power up for years to open a viable 'slipstream' ablel to carry a significant amount of mass. (the basic point of this is, we have colonies, but aren't anywhere near proficient in stellar travel) We stumble upon a world with sentient life, they are of course, humanoid, but are not as advanced as us... until a scientist discovers and proves that some parts of their anatomy cannot have evolved naturally, and they and a small group of fauna on the planet are radically different in make-up from other fauna on the planet... --> leads to a search for their 'home' planet through anthropologic/archeological trips to the planet, and the recon/research group becomes stranded when... something happens... and have to live on their own...

3. Fantasy/Sci-Fi story, set on a unknown world, almost industrial age technology, but industry is not thriving (i.e. no industrial revolution) because there is a sect of 'magik-wielders' who have arcane knowledge, and are sabotaging industrial progress. The story would revolve around a knight of the sect, who is dissatisfied, and so becomes recruited by a law-enforcement officer... detective kinda guy. They become alienated by both sides (ie. da magik sect and the technology ppl), and become fugitives. In their travels (they have to travel, they can't really stay in one place for long) they uncover collaboration between the two opposing sides (magik and tech), and either a) expose it, or b) find that there is someone behind the scenes and pulling the strings...

Project Description
This project is about keyboards, and how they work. This presentation will be on Microsoft Powerpoint, and this report is written and editted in Microsoft Word. Adobe Photoshop was also used for the background in the presentation.

IPO Chart

Input: Text from keyboards, clicks from mouse
Processes: Formatting of text in both word and powerpoint. Used brushes and filters in Photoshop, to create background.
Output: Final report on paper, presentation saved on school network.

Project Log
1st March
Started researching for presentation, had a look on

5th March
Started seriously researching, looked through, did some background research on the dvorak layout and forgot all about the actual project. I must keep on task in the future.

8th March

Researched gantt chart, googled and downloaded ganttproject 2.0. I had a fiddle with it for about 5 min, then went to wikipedia and read most of the keyboard related articles. should start presentation soon, due this time next week.

11th March

Decided to work on and hopefully finish the presentation today. All was fine and good, until I attempted to backup. Hit ctrl + s, and suddenly the computer restarted. This has happened before, but only when playing ultra resource hogging games. Tried to do presentation again. Crash and restarted. Gave up on powerpoint, decided to do a gantt chart in excel. I managed to get a graph that looked kinda like a gantt chart. I leant back from the keyboard for a sec, and the computer crashed AGAIN. I was very annoyed at that stage, decided to let the computer rest overnight.

12th March

This was a bad day. I tried to do a different project first, tried to start typing it up in ms word, it crashed as soon as it loaded. Rebooted. Decided to print something off from, but computer crashed as soon as the print command thing was sent. Was confused. Decided to try word again. Crashed. Tried powerpoint. Crashed. Gave up, and decided to try and do it monday morning. Very panicky at this stage

13th March
Got up extra early to try and do the powerpoint at school. managed to do half of it. asked ms. chen for an extension, as i could only do it at school. got one, then off to the library to do some more.

14th March
Almost completed powerpoint in class today, will not be able to finish by wednesday. Maybe thursday.

15th March.

Did some more work in the morning, fixing up powerpoint. was not able to work in class, had to pay attention to presntations.

16th March.

Added a background to presentaion, completely finished. decided to compress some of the points in the powerpoint, and copy the excess to word for my accompanying speech. got some more pictures also. bell rang, and i went to print off the speech when word suddenly froze. started panicking, as the word document hadnt been saved yet, and most of my points were on it. quickly saved powerpoint, although in hindsight i should have just left it and lost my lunches work, instead of a couple of days work. Unable to access powerpoint from home, so unable to work out a rough speech. ill see if i can do it before sd tomorrow.

17th March

Decided not to have a speech, but to rather do it ad lib. I am sure i can remember most of what i researched.

Documentation of backup procedures
I attempted to backup my powerpoint, however the computer crashed before the file was saved, resulting in the loss of data. I should have been able to autorecover, although this did not occur. The reason for this is that I finished the first draft of my presentation in under the thirty minute mark, when autorecover first saves. If I had been able to save however, I would also have copied the file to memory stick, saved it at school, and also emailed it to myself.

ag draft, published after final is finalised

The Goals of this Development Plan
The goals of my development plan are:
To increase the aesthetic appeal of the development area and introduce a pleasant smell into the area.
Increasing privacy in and around the development area
Reducing the work required to look after the garden (easy care)

Climatic Conditions around the Development area
The garden faces towards the southwest, while winds around the garden do vary as they begin to pick up speed as autumn starts and then turning into heavy winds that occur every week or so in winter. As the weather becomes warmer, the winds do tend to die out although during summer a few mild breezes may blow. *Temperatures do vary and the monthly minimum and maximum temperatures can also vary depending on the season. In summer the area experiences a monthly maximum and a minium of respectively of 21 °C and 18°C. In winter temperatures can peak at a maximum of 18°C and a minimum of 13°C.

*Please note that this information may have changed due to increase in temperatures due to human interference i.e. global warming and urban heating.

Special conditions within the Garden
The position of the garden does give the plants an advantage over other plants. The development area is a balcony which is located on the topmost floor. This allows more sunlight to reach any plants that maybe located on the development area, benefiting the plants’ growth and nutrient intake.

How the plan will achieve its goals
The garden development plan will achieve its goals by:
Purchasing tall, large plants that will provide privacy
Purchasing plants that are easy to care for and creating a system that does not require much maintenance or care.
The purchase of plants that will enhance the aesthetic appeal of the development area.
The purchase of plants that will introduce a new pleasant smell into the development area.

Problems that maybe Encountered
Problems will be encountered as the development plan is implemented so that the 3 goals may be achieved. Those problems are:
Cost i.e. size of the budget
Climatic conditions of the plants and the area

Solutions to the Problems
The problems mentioned above can easily solved by:
Selecting plants and materials that are effective in achieving the 3 goals but are relatively inexpensive.
Spacing can be overcome by buying plants that do not require large pots but have provided a reasonable amount of coverage and shade.
The appearance problem can be rectified by purchasing good looking plants that also fulfil the goals that have been set.
To solve the climatic conditions problem hardy and adaptable plants as well as plants suitable to the climate of the garden development area must be found and purchased.

The Landscaping
Landscaping is not an available option for the garden development area as it is too small and, landscaping would hardly have any impact on the aesthetic appeal of the development area. Also no landscaping changes are required in my plan.

Choice of Plants and why they were chosen
The following plants were chosen:
Golden Cane Palm
Mock Orange

They were chosen because:
The Golden Cane Palm was tall, able to provide shade and was suitable for increasing the privacy of the development area.
The Clivia plant was chosen for the same reason as the Golden Cane palm although it was smaller. It is also affordable.
Totem was very appealing and would probably be able to increase the aesthetic appeal of the development area.
The Cumquat was selected because the fruit combined with the plant itself was deemed to be able to contribute to the aesthetic appeal of the garden.
Mock Orange was chosen because of the scent that it had. This could introduce the pleasant smell that was wanted in the goals.

All of these plants are affordable and are easy to incorporate into the garden development area.

The budget will be approximately $300. The prices of the plants that were selected are listed below:

Name of Plant
Golden Cane Palm
Mock Orange

SD work


1. Explain the functions of the operating system. Give examples of some operating systems in use today.

An operating system usually provides the link between the application program and i/o devices.
Its main tasks are in the management of resources and to isolate the user from the direct use of hardware items.


Custom software is specifically designed to meet a need that off the shelf software will not meet.

Dedicated software is purchased by the user to complete a specialised taks.

Custom software: Adobe Photoshop
Application software: Oasis
System software: Macintosh


The user wishes to perform an application task. When switched on, the computer runs a bootstrap program stored in ROM which automatically loads the operating system, stored on the disk drive, into RAM. This then allows selective access to the application programs, also stored on the disk drive. Once selected, the application programs is loaded into RAM and begins running. The user is then able to perform the task required. The instructions from the from the application programs work together with the instructions in the operating system to allow appropriate application input, processing of the data and production of the required outpot. When the user has finished the task, the application program is removed from the RAM.


a) The function of a bus is to carry electronic signals between cpu and other system devices
b)Ram-cpu-rom uses bus, outside hardware-inside is cable.


b) Cable connects externally, and bus is internal.


A buffer is temp stoarge.


Microprocessor chip and memory chip.


A peripheral is an external device attached via cable


The purpose of any computer system is to input data, process it, and output it.


System software controls the hardware of a computer system.


The bootstrap program is in ROM


When you start your computer you must turn on the power. Modern computers are electrical machines. They have a electrical power supple which moderates the normal electrical current and voltage to make them the correct values to be used in all the parts of the computer. All of the hardware devices which make up a modern computer use electrical power. If their electricity power supply fails no computer can operate for very long.

Exercise 2.11

1/ Hardware foolows the instructions provided by software. The CPU moves through the steps of the fetch-execute cycle as it executes the instructions one by one, The first stage in the fetch execute cycle is for the central processing unti to fetch the the instruction.This step is followed by the process of decode, where the central processing unti works out what to do. The last two steps are called the execute-store cycle. This cycle begins with the cpu carrying out the instructions, following which the central processing unit sends the result to primary storage.
