1. Radio Botton: Choice to allow one choice from each group of choice

Check Box: Choice button to allow more than one choice from each group

Command Button: A graphic labelled with text to indicate its function.

Cursor: Used to indicate the state of the system.

Text Box: Objects that contain text.

2. GUI or a graphical user interface is a user friendly environment which is simple and easy to use for novice or beginning programmers. This type of programming allows beginners to place objects into their forms such as buttons, text, boxes and data. They also allow the use of a wide range of data types. The smallest type of meaningful data used in any program is a character. Numeric data may be either integers or real numbers, also called decimals. Any series of characters is known as a string with special use of variables called the boolean data type used to hold only 2 possible outputs, such as .

3.

Data: cm and Inches

Types of Data

Numbers

Integers / floating point

Integers – Whole numbers

Floating Point – decimal number (with decimal places)

                        - Different languages with different terms for floating point numbers (e.g. Pascal uses REAL, Visual Basic.NET uses DOUBLE)

String

Alphanumeric data / text

Boolean

True/false

EBCDIC – Extended Binary Coded Interchange Code (8bits)

1bit      – the smallest unit of measurement holds a 1 or 0

8bits     – 1byte

1024 bytes – 1 kilobyte

1024 kb      – 1 megabyte

1024 mb     – 1 gigabyte

1024 gb      – 1 terrabyte

1024 tb      – 1 petabyte

1024 pb     -  1 exabyte

1024 eb     -  1 zettabyte

1024 zb     -  1yotabyte

Paint: Recent versions of Paint allow the user to pick up to three colours at a time: the primary colour (left mouse click), secondary colour (right mouse click), and tertiary colour (control key+ any mouse click).

The program comes with the following options in its Tool Box (from left to right in image):

The Image menu offers the following options: Flip/Rotate, Stretch/Skew, Invert Colours, Image Attributes, Clear Image, and Draw Opaque. The “Colours” menu allows the user to Edit Colours (only menu option under Colours). The Edit Colours dialog box shows the standard Windows colour picker which includes a 48-color palette and 12 custom colour slots that can be edited. Clicking “Define Custom Colours” displays a square version of the colour wheel that can select a custom colour either with a crosshair cursor (like a “+”), by Hue/Saturation/Luminance, or by Red/Green/Blue values. There are 28 colour wells in the workspace.

Advantages

Paint: The main advantage of paint is that it comes free if you are using windows operating system. It is the best tool for introducing new users to working with a graphics program as its simplicity and small size makes it easier to learn. It is a very basic image editor and does not require a great deal of system resources in order to run. This is an advantage for an old computer. It is also bug-free software.

Adobe Photoshop: It has great tools photo colour correcting and image manipulation. Its user friendly, multi-purpose, very comprehensive graphics program and excellent features. Photoshop is a vital program because it contains superior CMYK CLUT’s (colour lookup tables.)

Disadvantages

Paint: watermarking in Paint is not so easy and quick. Avery limited graphics program. It has very basic editing capabilities. Works only on windows operating system. It does not support layers.

Adobe Photoshop: Loading interface takes quite long, need to experiment in order to know the tools and features. Takes time to get used to the features and totally the whole program. A legal license for Photoshop is very expensive, and memory intensive as well if you work with high res graphics.

The best software package is Adobe Photoshop because of its high end graphics manipulation and easy to use tools which allow you to make easy image editing, animation and authoring. Adobe Photoshop is more user – friendly.

Problem-oriented languages, translation with compilers or interpreters, structured programming, database management systems. Typical languages: COBOL, FORTRAN, Pascal, Ada, C, BASIC, PL/I.

Fourth Generation (4GL):

non-procedural languages, integrated data dictionaries, dynamic relational databases; makes possible rapid system development and prototyping. Typical: FOCUS,
