| Question | Answer |
| what is psuedocode | a simplified version of code which is the root of all programing language. |
| what is a algorythem | step by step instructions for a computer to folow |
| flowchart: start/stop | flowchart: oval |
| flowchart: process | flowchart: rectangle |
| flowcharts: input/output | flowcharts: paralelogram |
| flowcharts: pre-defined process | flowcharts: rectangle with lines at the edges |
| flowcharts: decision box | flowcharts: diamond |
| flowcharts: connectors | flowcharts: arrows |
| logic gates: and | half circle half square both elements have to be true to go to z |
| logic gates: or | curvy kite one of the elements need to be true to go to y |
| logic gates: not | triangle with dot statement need to be false to go on |
| integer | a number |
| double | a decimal number |
| string | multiple characters |
| boolean | true false, yes no, 0 1 |
| char | one single character |
| variable | a thing which holds a value and that value can be changed through the program, in VB to iniiate a variable you do Dim (var name) As (datatype) |

| Binary | A piece of code that only involves zeros and ones, this is known as Base 2 |
| denary | This piece of code only involves 10 digits. The system contains number from 0 to 9, not 10 as the computer counts the zero as part of the 10 numbers also known as Base 10 |
| Hexidecimal | A piece of code that uses 0 to 9 but as well as that uses A to F so 16 numbers |
| computer systems | A system of interconnected computers that share a central storage system and various electronic devices such as a printers, scanners, or Wi-Fi. |
| data processing | using input devices data processing – using a microprocessor, typically the Central Processing Unit (CPU) |
| record | a horizontal line of info. contains info about one particular thing |
| primary key | a number which represents a record |
| field | the verticle information. conatins answers to one single question e.g. all of the name or all of the ages |
| entities | things in a database which we want to know about e.g. in a register (yes that's a database) the entity would be pupils |
| queiry | A query is a request for data or information from a database table or combination of tables |
| forms | a simple user interface that fill data into a database |
| CPU | The CPU is responsible for executing a sequence of stored instructions called a program. |
| GPU | Graphics Processing Unit: These features are designed to lessen the work of the CPU and produce faster video and graphics. |
| RAM | RAM is a fast temporary type of memory in which programs, applications and data are stored. where the operating system, applications the graphical user interface (GUI) are stored. If a computer loses power, all data stored in its RAM is lost. |
| Disk Drive | A place where you put in a disk and the computer reads the disk |
| two types of storage | SSD (solid state drive) HDD (hard disk drive) |
