TOPIC: STAGES IN DATA PROCESSING
The repetitive nature of data processing can be well described as a processing cycle. It is simply a sequence of procedures or steps required to perform a given task repetitively.
Stages in data processing refer to various stages which data passes through before it becomes information. The stages include:
- ORIGINATION OF DATA This can be described as the creating and gathering of data from elements such as source documents.
- PREPARATION This step is associated with the transcription, sorting and arrangement of data before entry into a computer.
- INPUT DATA This is the process of entering data into the computer. It is the entry of data through the input devices e.g. keyboard.
- PROCESSING OF DATA It concerns all exercises of data processing such as calculating, sorting and classifying.
- OUTPUT OF DATA The desired end of the processing of data will finally be reached and produced. The output in soft copy or hard copy will take the shape of written reports, graphical representation, drawing, etc.
- STORAGE OF DATA This is the process of saving the result of the processed data in a manner that will permit easy retrieval.
- When data is fully processed it becomes ………………. (a) information (b) word (c) sentence (d) Raw
- The process of converting data into meaningful information is called………..(a) data processing (b) data creation (c) sorting (d) None
- The document of which data is first recorded is called ……………… (a) source document (b) object document (c) real document (d) code
- The process of getting data from source is called ………………. (a) data creating (b) data preparation (c) data validation (d) data collation
- Sending and receiving of data via telecommunication network is called …………….. (a) data transmission (b) data processing (c) validation (d) Output
