Variables

Variables

Programs may need to store data when running and it stores that data in a variable A variable is a named storage location in the computer’s memory The following types of data (or variables) can be stored: local variables parameter variables class-level variables world-level variables
Alice

Alice

A tool for learning algorithmic problem solving 3-D graphics 3-D models of objects Animation Objects can be made to move around the virtual world (a video game or simulation implemented in 3-D)
Custom Methods

Custom Methods

Some actions are naturally associated with a specific class of objects. Examples A person walking A wheel rolling We can write our own methods to define actions for a specific class of objects; These methods are known as custom methods.
Boolean Values

Boolean Values

4.1 True or False? Boolean values are abstract concepts used in computations?
Interactive Animations

Interactive Animations

Flow of Control -- how the sequence of actions in a program is controlled. What action happens first, what happens next, and then what happens…and so on. In movie-style programs the sequence of actions is determined by the programmer Creating a storyboard design Writing program methods to carry out the designed sequence

Writing Methods What is a method? set of instructions that execute create methods by dragging tiles into the Method Editor these tiles are the instructions my first method
Functions

Functions

A function asks a question (to check a condition) or computes a value. In Alice, a function is used to get the information we need about the properties of objects Is the snowwoman's face red? the relationship of one object to another What is the distance between the mummy and pyramid? a current condition What key (on the keyboard) was pressed? Let's look at an example…

Factors for Routing Algorithms

Factors for Routing Algorithms

Performance Criteria: Source of Network Information: Number of hops None Cost Local Delay Adjacent node Throughput Nodes along route   All nodes Time When Decision is Made:   Packet (datagram) Time of Network Information Update: Session (virtual circuit) Continuous   Periodic Place Where Decision is Made: Major load change Each node (distributed) Topology change Central node (centralised)   Originating node (source) Routing algorithms written to maximise performance of network (hence performance criteria) Draw a network of routers and explain each criteria However, lots of other factors to be taken into account when designing or choosing a routing algorithm. ‘Node’ = router Why does it make a difference which option is chosen for each factor? – take each factor in turn and explain
LAN Design Goals

LAN Design Goals

Frequent goals of network design: Functionality - the network must work Scalability - the network must be able to grow Adaptability - network must be able to adapt to new technologies Manageability - network must facilitate network monitoring and management These goals are typical of most networks ·         Functionality-The network must work. That is, it must allow users to meet their job requirements. The network must provide user-to-user and user-to-application connectivity with reasonable speed and reliability. ·         Scalability-The network must be able to grow. That is, the initial design should grow without any major changes to the overall design. ·         Adaptability-The network must be designed with an eye toward future technologies, and it should include no element that would limit implementation of new technologies as they become available. ·         Manageability-The network should be designed to facilitate network monitoring and management to ensure ongoing stability of operation.

Challenges of Managing Large Networks

Network critical to running of business Complexity of network – requiring automated management tools Large number of devices, increased probability of device failure Likelihood of devices from different manufacturers Physical distribution of network assets – requiring management of assets across the network itself
