15/10/08

Today we went to a new website that Mr. Lennon said that we would be using this term. This site was 'http://scratch.mit.edu'
It was a site that basically allows you to play games.

Later, we played around with a new program called 'SCRATCH'. It's a program that allows you to make little animations and put them in motion.

Today is the first day back from the holidays and at first in our lesson we had to find out what certain words meant.



BACKGROUND ON PROGRAMMING



- ALGORITHM

- PSEUDOCODE

- MACHINE CODE

- HIGH LEVEL PROGRAMMING LANGUAGE

- FLOW CHART SYMBOLS





ALGORITHM - An algorithm is a procedure or formula solving a problem



PSEUDOCODE - Pseudocode is a kind of structured english for describing algorithms.



MACHINE CODE - Machine code is the elemental language of computers, consisting of a stream of 0's and 1's



HIGH LEVEL PROGRAMMING LANGUAGE - A system for communicating using symbols

FLOW CHART SYMBOLS -
Terminator - Terminators show the start and stop points in a process. When used as a Start symbol, terminators depict a trigger action that sets the process flow into motion.
Process - Show a Process or action step. This is the most common symbol in both process flowcharts and business process maps.
Predefined Process(Subroutine) - A Predefined Process symbol is a marker for another process step or series of process flow steps that are formally defined elsewhere. This shape commonly depicts sub-processes (or subroutines in programming flowcharts). If the sub-process is considered "known" but not actually defined in a process procedure, work instruction, or some other process flowchart or documentation, then it is best not to use this symbol since it implies a formally defined process.
Alternate Process - As the shape name suggests, this flowchart symbol is used when the process flow step is an alternate to the normal process step. Flow lines into an alternate process flow step are typically dashed.

ETC.
