- 1NetworkA group of computers connected
together so they can communicate - 2LANLocal Area Network
- 3WANWide Area Network
- 4TopologiesThe layout of computers and
other elements of a network - 5Topologies- BusA single cable that runs through
the network. All of the devices
are connected to this. - 6Topologies- RingAre connected to each other in a ring.
Communication only goes in one
direction. It passes the message to the
next computer - 7Topologies- StarAll computers are connected to a central switch. The switch directs the traffic
to the appropriate computer. - 8AddressA unique identifier given to something
such as a house address. Computers on a network also need an address to identify them - 9Address Format32-bit binary value, this means it is made of 32 1s and 0s.
- 10What is the internet?A huge, global inter-connected network of devices.
- 11Internet TopologyThe layout of these nodes is called a Mesh Topology. Messages can take many different routes to each destination
- 12RoutingThe messages take a certain route, each node continually tests its connections and assigns them a "cost"- a lower cost means faster connection
- 13PacketsHuge amounts of data travels around the internet. All data on the internet is split up into small chunks called packets. Each packet is numbered and sent independently.
- 14What do spreadsheets do?For performing calculations and analysis of data. Spreadsheets can perform complex functions on data.
- 15CellThe spreadsheet is a grid. An individual rectangle in this grid is called a cell. Each cell has a unique cell reference, named after the columns letter and the rows number
- 16ColumnA vertical group of cells that extends infinitely is called a column. A columns reference is the letter above it
- 17RowA horizontal group of cells that extends infinitely is called a row. A rows reference is the number to its right.
- 18FormulasMathematical formulas can be entered into a cell instead of a value. All formulas must start with an "=", otherwise they wont be evaluated
- 19Formulas- symbolsAny mathematical calculation can be performed. Because the × and ÷ symbols aren't on the keyboard, * and / are used
- 20FormattingFormatting is the process of changing the colours, borders, fonts and data types of cells to make it easier to follow.
