Software, Compiler, Disadvantages - Coggle Diagram

- - - - Human Computer Interface
        
        Provides interface between user and system
        
        GUI - Graphical User Interface
        
        CLI - Command line interface
      - Users
        
        Including user accounts, passwords and levels of access and biometric database
        
        Levels of access - create, read, write, amend, delete
      - Memory
        
        It knows when RAM is full and partitions a swap space in virtual memory
      - Peripheral devices
        
        Using interrupts
      - Security
- - - - Portable (Can be moved between different hardware architectures)
        
        Easier for programmers to learn and comprehend - uses english and mathematical symbols
    - - An interpreter reads statements from the program written in high level language, translates it and executes the statement. This process is repeated for all remaining statements.
        
        Programs have to be compiled every time they are run. If an error occurs, execution ceases and an error message is sent along with the line of code that the error has occurred on.
        
        Simulates a computer that understands high level languages. E.g. Python, Java
        Python is an interpreted programming language and an example of an IDE (Integrated Development Environment). Interpreted programs are portable, which means they will run on any device. A program written on a Macbook will also work on a HP laptop.
      - Advantages
        
        More flexible - you don't need to go through the steps of compiling and executing a program.
        
        Will read the program line by line and stop when there is a problem.
      - Disadvantages
        
        Programs cannot be run without the interpreter
        
        Programs will take longer to execute
      - Interpreters are more commonly used for developing programs
  - - - Takes up very little memory
        
        It is fast to run/execute - it directly manipulates the hardware.
    - - Takes a lot longer to write and debug programs
        
        Harder to understand
    - - All instructions use binary, written as string of ones and zeros
        
        Only language that is directly understood by the computer
    - - The assembler converts the assembly language to machine language for the machine to understand.
        
        An assembler is a computer program that translates assembly language into machine code so the task can be executed. Assemblers use mnemonics/hexadecimal/ symbols and abbreviations.
  - - - Run-time environment - Runs the program under development and allows the programmer to move through the program to run one line at a time or to set a breakpoint to stop the execution of the program at a certain point of the source code.
        
        Program translators - Stops each time there is an error
        
        4. Error diagnostics - Information that is presented following the detection of some error condition and is mainly intended to assist in identifying the cause of the error.
        
        Auto-completion - offers suggestions for text competition such as variable names and reserved words
        
        6. Auto-correction - Dynamic error checking finds possible errors as the program is being typed and alerts the programmer when an error has been detected and suggests a correction.
        
        Prettyprint - Utility module in Python, colour codes the key components of the program, such as variables.
