What is Windows Azure?
Set of tools for cloud computing. Storing and managing databases, storing and running softwares, etc.
Ex: Host websties and web applications.
What is a float?
A data type that represents fractional numbers.
What is floating point number?
A method for representing the same fractional number in several possible ways.
3425 = 3.425 X 10 ^ 3
3425 = 34.25 X 210 ^ 2
The result is that the point floats through the different numerals.
What is a Registry:
A place where records are kept.
What is a Registry in Windows?
A database that stores settings of the operating system, drivers and applications.
Ex: when a new program is installed, instructions (such as how to start it and how the program should work) are stored in the registry.
What is KVP?
Key-value pair.
Two linked data:
- Key -> a unique identifier for some data.
- Value -> the data identified by the key.
What is a Tree?
A nonlinear datas structure.
What a tree is composed of?
- Nodes.
- Arcs or edges.
What are nodes?
A simple data structure that holds data and links to other nodes.
Which are the two special case of nodes in a tree?
- Root node.
- Leaf node.
What is a Root node?
The first node of a tree. It has no parents.
What is a leaf node?
A node at the end of a branch. It has no children.
What is an Arc/edge?
The representation of the relationship between nodes.
How is called the relationship between nodes?
Parent/child relationship.
What is a subtree?
The repetition of the tree structure at each level.
What is a binary tree?
A tree with thre restriction that nodes can have no more than two children.
How you can implement a binary tree in memory?
Each node of the tree should be compose of tree values: the data of the node and two pointers. Each pointer will point to the data of a child node. The leaf nodes will have null value for the pointers.
What is a subkey pair in the windows registry?
Its a node in the tree data structure of the windows registry. It’s the key + value.
What tool can be used to launch the windows registry?
Windows Registry Editor or Regedit.exe.
What is a flowchart?
Diagrams that represent algorithms, workflows, or a process.
Like a blueprint of the program, flowchart is a solution that breaks the problem bit by bit in order to facilitate understanding of a problem.
Describe the Terminator flowchart symbol.
A rectangle with rounded cornes.
Indicates the beginning and the end of the program.
Describe the Decision flowchart symbol.
A diamond shape.
Indicates a decision point between two or more paths in a flowchart.
Describe the Process flowchart symbol.
A rectangle.
Indicates any processing function.
Describe the Dataflowchart symbol.
A parallelogram.
Can represent any type of data in a flowchart.
