Worksheet time: 14mins
What two topologies do you need to know, and be able to explain, for your exam?
Bus
Star
Ring
Mesh
Which of the four statements on Star topology is incorrect?
It is easy to add a new node
There is a hub or switch at the center of the network
If one node goes down the whole network stops working
Network traffic is kept to a minimum
Which of the four statements on Mesh topology is incorrect?
Data can be transmitted form different devices at the same time
If one node goes down there is always another route for the information to flow
Adding more device will not slow the data transmission
Over all cost is low as it does not require much cabling to set up a wired network

Body
Footer
Header
What is the name of the address hard coded into each and every network device and cannot change.
IP Address
MAC Address
Which is a feature of a Mesh Network?
Data can be transmitted from different devices simultaneously
Devices are dependent on a central sever.
The network uses terminators
The Server is usually based in the middle of the network
What is meant by a data packet?
A unit of data that travels along a network
The number of error found in data when it has been transmitted
The data a computer needs to connect to a network
A connection point in a network that allows data to be shared

Which generation would create the fastest code to execute?
1st Generation - Machine Code
2nd Generation - Assembly Language
3rd Generation - High Level Language
4th Generation - Declarative Language
An advantage of programming in a high-level programming language is:
Uses natural language and so can be easier to read/understand
Useful for device drivers
The final file size is smaller
Programs run more quickly at runtime
Software program which optimizes code, ready for execution:
Language Translator
Compiler
Interpreter
What is meant by source code?
The final executable program
The code written by the programmer
The additional information about errors
Code relating to sources of information on the Internet
Nearly all IDEs will have this to manipulate source code
Debugger
Compiler
Text Editor
Helps identify and fix errors in code
Debugger
Compiler
Text Editor
Translates source code from a high-level language to a lower level language
Debugger
Compiler
Text Editor
What is a debugger?
The final executable program
The code written by the programmer
Assists in the detection and correction of errors
Translates code
