  1. 1CPU Central Processing UnitThe brains of the computer that can Fetch, Decode, Execute instructions
  2. 2Fetch, Decode, ExecuteFetch: the instruction.
    Decode: the the instruction.
    Execute: the instruction.
  3. 3CoresCore(s): how many possessor there are in the CPU that can fetch, decode, execute at the same time.
  4. 4Clock SpeedClock speed: the amount of times per seconds each core can fetch, decode, execute.
  5. 5Memory storage'sCache
    Ram
    Hard Drive
  6. 6CacheCache: A small easily accessible memory storage in the CPU, this makes it really easy to fetch, decode, execute.
  7. 7RamRandom Access Memory (RAM): A bigger memory storage located further away from the CPU. Therefore takes more time to fetch, decode, execute.
  8. 8Hard DriveHard Drive: The biggest storage, located furthest from the CPU, it therefore takes longest time to fetch, decode, execute.
  9. 9CPU partsThe Control unit
    The Arithmetic logic unit (ALU)
  10. 10The Control UnitThe control unit controls the 'Fetch' part of 'fetch, decode, execute'
  11. 11The arithmetic logic unit (ALU)The ALU controls the 'decode' part of 'fetch, decode, execute'
  12. 12RegistersThe parts that control the 'execute' part of 'fetch, decode, execute'
    Accumulator (ACC)
    Memory address register (MAR)
    Memory data register (MDR)
    Program counter (PC)
  13. 13VariableA value stored in memory that can change
  14. 14SequenceThe order in which the code runs
  15. 15SelectionA programs decision to run code based on meeting certain conditions
  16. 16StringA collection of letters, numbers and symbols
  17. 17integerwhole number
  18. 18Booleantrue or false
  19. 19Charsingle number, letter or symbol
  20. 20Real/FloatDecimal
  21. 21CastingConverting one data type to another
  22. 22=assign a value
  23. 23==compare a value
  24. 24ArrayA series of memory locations for storing the same type of data
  25. 25Logic ErrorWhere the code runs but not as expected
  26. 26run-time errorAn error that occurs while the program is running
  27. 27Syntax errorErrors which break the grammatical rules of the programming language and stop it from being run
  28. 28IterationRepeating steps over and over again in a loop
  29. 29Count controlled loopRepeating code for a set amount of times
  30. 30Condition controlled loopRepeats code while a condition is being met
  31. 31ConstantA value stored in memory that does not change whilst the program is running
  32. 32NetworkTwo or more networks connected together in order to communicate and share resources
  33. 33Nodea device connected to a network
  34. 34Packeta chunk of data that forms part of a message
  35. 35HardwareThe physical parts of a network
  36. 36LAN local area networka network that covers a single building or a small site
  37. 37WAN wide area networka network that covers a large geographical area of at least 1 mile
  38. 38routersa device that sends packets between networks it makes decisions about where to send data an by what route
  39. 39WAP wireless access point (wireless network point)a device that allows devices to connect to a network using standards such as Wi-Fi and Bluetooth.
  40. 40switchfilters and forwards data packets to the intended receptant
  41. 41HubFilters and forwards data packets to all connected nodess
  42. 42NIC Network interface controllerA computer component that allows a computer to connect to a network
  43. 43MAC address Media access control addressa unique number assigned to each NIC, identifies any device on a network
  44. 44IP address internet protocol addressa unique number that identifies a device on the internet (usually assigned to a router) and can change
  45. 45ServerHigh end machine that manages a network
  46. 46client network servermost common way to organise a LAN, one or more computers are designated servers. as server typically looks after: logins/security. file handling, printing and internet access
  47. 47Peer to peerall computers are considered equal funcunality can be divided amongst nodes each computer works as a server.
  48. 48Topologythe physical layout of a network
