Von Neumann Model

Imagen
  Von-Neumann proposed his computer architecture design in 1945 .  He wanted a model in wich the instruction data and progam data were stored in the same memory.  COMPONENTS OF THE VON-NEUMANN MODEL:  CPU: Electric circuit responsible for executing the instructions of a computer program. Inside the CPU, we can find:  The ALU ( Arithmetic and Logic Unit) performs micro-operation for executing the instruction The registers   are  high-speed storage areas in the CPU. The data processed by the CPU are ran from the registers. The Control Unit controls the operations of the ALU, the memory and the I/O devices.  BUSES: Means that conect the CPU, the memory and the peripherals.  Address Bus Carries the address of data (but not the data) between the processor and the memory. Data Bus Carries data between the processor (CPU), the memory unit and the input/output devices. Control Bus Carries signals/commands from the CPU. MEMORY UNIT: Stores binary i...

Use of sound compressors and limiters

Imagen
  SOUND COMPRESSORS A compressor is a tool used to reduce the dynamic range of an audio signal. "Dynamic range" is understood as the difference in decibels between the highest and lowest peak of the signal. Therefore, the compressors are going to help us to reduce that difference.  Basic configuration parameters:              LIMITERS A limiter is an audio processor regardless of hardware or software that prevents the signal from increasing in volume above a set level.

MS-DOS

Imagen
MS-DOS , in full Microsoft Disk Operating System .  MS-DOS allows the user to navigate, open, and otherwise manipulate files on their computer from a command line .  HOW TO ACCESS MS-DOS?  Click on the Windows "Start" button. Select "Programs" Select "MS-DOS Prompt"  EXIT:  exit [/b] [<exitcode>] BASIC COMMANDS: COPY Syntax of this command is “C:\>copy [desired file name and address] [destination address]” . This command is used to copy a file from a drive to another drive. RENAME Syntax of this command is “C:\>ren [old file name] [new file name]” . This command is used to rename a file. Simply out the old name of the file and new name of the file and press enter. Your file name will be renamed. DELETE Syntax of this command is “C:\>del [path and filename]” . This command is used to delete a file from a directory or a folder.
