Windows 7

Today we are in another classroom with no computers, due to year 10 exams in the computer rooms. So our teacher printed sheets about Windows 7. We just read it and had to answer some questions.

1.What versions is Windows 7 available in ?

• Home premium
  
• Professional
  
• Ultimate


• OEM


• Enterprise
  

2.Describe some of the features of the new task bar.

Pinned programs usinglarge, easy-to-see icons. Mouse over one and all windows associated with that program appear in preview. Hover over the preview to show a full-size preview of the program.

3.What are jump lists and how will they be useful?

Jump lists are made to make the recently opened documents easier to get to.

4.How can one quickly size two windows to fill the desktop side by side?

If you want to use 2 programs at once.

5.Research and describe the 9 multi touch gestures that windows 7 uses?

Tap and double tap; Basic touch action. This is what a click and double click does.

Panning with Inertia; This is for scrolling. Drag any part of the page up or down with one or more fingers. This works in most applications that use standard scrollbars.

Selection/Drag; This is like drag ans selection. Touch and slide your finger on the screen. This will move icons around the desktop.

Press and tap with second finger;This is like a right click. Press on target and tap uising your second finger.

Zoom;This is the same using the CTrL key + scrolling. Pinch two fingers or apart to zoom in or out on a document.

Rotate;Touch two spots on a digital photo and twist to rotate it is just like a real photo. Move two fingers in opposite directions or use one finger to pivot around another.

Two finger tap;Tapping with two fingers zooms in about the center of the gesture to default zoom.

Press and hold;Same as right click. Hold your finger on screen for a moment and release after the animation to get a right-click.

Flicks;Flick left or right to navigate backwards and forwards in a browser or application. This is very natural when one wants to flick.

Scratch

Today i also started playing around with the program called scratch. It looks pretty hard soo i am going to see wat i can get out of it today. So far i got the three control structures and they are:

• sequence



• selection
  


• repetition

Sample flowcharts

Basically the flowcharts just explain the steps of what you are doing. You just need to follow the instructions in the flowchart.

“Computers never do what you want them to do, they only do what you tell them to!"

Algorithms: an algorithm is an effective for solviong a problem using a finite sequence of instructions.

Pseudo code: This cannot be compiled, there is no real formatting rules. It is simply just one step - in producing the final code.

Machine language: Only used by the languages that are understood by the computers. This is almost impossibel to use because it it entirely numbers.

High level computer language: These are translated into assembly or machine language by a complier.
