hi, my name is Anisha and I study in standrews international school. This is my learning page and I hope you enjoy it.


Computer controlling can control alot of things ex.fish tanks, heat sensors and traffic lights. All are controlled by one computer.
Now there are even green-house gases house which have electronic water sprinklers and sensors. Computer controlling can make life more easier and affordable.



Assessed by Karan. Peer assessment. Not alot of work in there. especially in level six. You need to cover more things

I do agree with everything by the peer assesment done by karan but for one of the features which was the annotation skill i think I have annotated it well and I should get a one for it. Next time I will follow the criteria properly and try use most of them.

The roles of computer are:

Computers can respond very rapidly to change.
Systems can run 24 hours a day, 365 days a year.
Control systems can operate in places that humans would find dangerous or awkward.Outputs are consistent and error freComputers can process data quickly and machines can operate faster than humans.



Today in the 19/01/12 I learnt about Controlling.

Control means to set a structure. Computer control normally has to do with robotic systems to work without human employees and to save time.
The control systems:
HTML: WEBPAGES
JAVA: GAMING
ROBOTS: LOGO
To control the robot first we have to start with "pen down". ex. pendown turn left 90 degrees to 3 metres.

2/2/12


Basic commands:
  • fd & bk
  • lt & rt
  • pu & pd

Control can be used in thermometer, hospitals, traffic signals amd even memory cards.

ADC is Analog-to-digital converter.
DAC is Digital to anator converter

2 new information that I learnt :
Pos :Returns a two member list with the x and y position of the turtle. You can either assign the list to a variable, or get a value from the list.
setpos [x y] :Sets the absolute x and position of the turtle. If the pen is down, it will draw a line from it's previous position.
ST :Shows the current turtle.

Today I learnt:
new formulas to do logo ex. repea

Pressure sensor
Signal sent to actuator to switch fan on or off




for my assesment i think i will get a 60 out of 1oo for doing a clorful logo and data valistaion wellfor the flowetr task i think i got a 60 out of 1oo as I used data validation but vlookup had got confusinh
