- 1The control unit is responsible for decoding the instructions. It sends out signals to control how data moves around the parts of the CPU (flow of data within the system)The ALU carries out the calculations and logical decisions required by the program instructions e.g. + - < >
- 2Accumulator (ACC) Memory Address Register (MAR) Memory Data Register (MDR) Program Counter (PC)Logic Error - Where the code runs but not as expected
- 3Run Time Error - An error that occurs whilst the program is runningSyntax Error - Errors which break the grammatical rules of the programming language and stop it from being run
- 4Variable - A value stored in memory that can changeSequence - The order in which the code runs
- 5Selection - A program's decision to run code based on meeting certain conditionsString - Collection of letters, numbers and symbols
- 6Integer - Whole numberBoolean - True/False
- 7Char - Single number, letter or symbolReal/Float - Decimal
- 8Casting - Converting one data type into anotherArray - A series of memory locations for storing data
- 9Network - Two or more devices connected together in order to communicate and share resourcesNode - A device connected to a network
- 10Packet - A chunk of data that forms part of a messageHardware - The physical parts of a network
- 11Local Area Network (LAN) - A network that covers a single building or small siteWide Area Network (WAN) - A network that covers a large geographical area of at least one mile
- 12Router - A device that sends packets between networks. It makes decisions on where to send data and by what routeWireless Access Point (WAP) - A device that allows devices to connect to a network using standards such as Wi-Fi and Bluetooth
- 13Switch - Filters and forwards data packets directly to the intended recipientHub - Filters and forwards data packets to all connected nodes
- 14Network Interface Controller (NIC) - A computer component that allows a computer to connect to a networkMAC Address - A unique number assigned to each NIC. Identifies any device on a network
- 15IP Address - A unique number that identifies a device on the internetClient Server Network - Most common way to organise a LAN. One or more computers are designated servers. A server typically looks after: Login and security, file handling, printing and internet access
- 16Peer to Peer Network - All computers are considered equal. Functionality can be divided amongst nodes. Each computer can act as a serverTopology - The physical layout of a network
- 17ASCII - ASCII code is where a number represents a character such as 'a' or '@'
