Hi! I want to share a method to easily convert a decimal number into binary number and vice versa. I learned this method of converting decimal to binary while I was studying for my C1003 Mathematics for Computing.

The Basic Concept

The basic concept of this method is looking at the fact that we just need to add one zero each time we multiply the decimal equivalent of a binary number by 2 (two).

Let me give an example:

I have posted the proposal for this module in the previous post. Now I will start to post the documentation of this module’s project.

TABLE OF CONTENTS

1.0 CURRENT SYSTEM

Super Gamers (SG) is a gaming center in Singapore that rent games from various game consoles for everyone to play on the shop. A group of university student founded it in 2001. SG was so famous among gamers in Singapore because it allows the member to play games with affordable price, vast selection of game console, and has a wide collection of games ranging from old era games to the most recent games. No wonder, SG has so many customers and keep increasing every year because of its excellent reputation.

Hi! This is the last module that I take in my IDIC (International Diploma in Computing) course, C Programming! Similar to C1004 HTML, this is a project based module that requires me to create a simple program using C language.

The documents that need to be submitted in this module are:

1. Project Proposal
2. Project Documentation
3. Working program (using C language)

An issue that me and my friends get when we start this project is to find an IDE (Integrated Development Environment)/Development software. Finally, we decided to use Borland C++ 5.02 it works quite good with only few errors.

The program that we need to create for this module is a program that have these five basic functions:

1. Add data
2. Display data
3. Update/Edit data
4. Search data
5. Delete data

Additionally,

Hi!
This time I will post the assignment that I get for C1022 Introduction to Java module in Term 1 2008.

SECTION A

A1.      Write Java statements to accomplish each of the following:

a)      Declare a variable ‘reply’ to be of type char.

char reply;

b)      To compare the contents of both variables ‘pass’ and ‘word’ of type String.

pass.compareTo (word) > 0;

pass.compareTo (word) == 0;

pass.compareTo (word) < 0;

pass.compareTo (word) > 0;

pass.equals (word);

pass.equalsIgnoreCase (word);

c)      To assign a float value 2.5 to a variable ‘number.

float number = 2.5f;

d)     Display a message ‘happy new year’ using a method from the Systems class.

Hi! This post is about my C1002 Program Design assignment that I take in Term 1 2008, this post will contain the assignment’s questions only, I will post the answer in the next post.

These are the questions:

Question 1

Scenario

The Post-office in country X still using a manual way of weighting the letters and check whether the senders have paid enough postage. The government wants the mail service to be computerized so the mailing process will be faster.

The proposed system is as follows:

All letters will go through machine A to capture the weight, and the computer will automatically calculate the postage value that the sender supposes to pay. Machine B will scan the value of the stamp and compare the value of the stamp with the required postage value. If the postage value is greater then the stamp’s value, a message will display on the screen so the operator can take action accordingly. This program will display number of letters that the postage are underpaid and paid correctly in the summary before the program end.

Hi! I would like to post my C1001 Computers and Information Processing module’s assignment, this was my assignment in Term 1 2008. Well, basically this module is the most basic module in IDIC (International Diploma in Computing) course. The assignment also just consist of simple questions and answer, not much research or self study need to be done.

So, here is my assignment:

1. Three Types of Scanners:

a) Optical Scanner

Optical Scanner is an input device that works using bright light that moves across paper or the document. After that, the image reflected through series of mirror and converted to digital signal by the software.

The image is stored as rows and columns of dots called bitmap.

b) Optical Reader (e.g. Optical Mark Reader)

Optical Reader is a device that able to read characters, marks, or codes from a paper, document, or any physical medium. Then convert it to digital signal that can be processed by the computer.

Kinds of Optical Reader are:
