Basic Software:
The basic software is also referred to as utilities. Basic software packages are available for performing operations such as data entry and validation, sorting and merging files and editing data. A data entry and validation software typically allows the user to define a format to be displayed on a screen (VDU) and by using other prompts enables data to be entered in the specific format defined by the user. Some simple checks on the data entered are also possible with this software, for instance, ensuring that there are no alphabetic characters in a numerical data field, etc. File sorting and file merging facilities are provided in such packages. Some sophisticated packages offer editing capabilities of certain specific lines in the text or even full
Q. Define the Register Addressing mode? When operands are taken from registers implicitly or explicitly it is known as register addressing. These operands are termed as regis
Functionality under load can be tested by running various Vusers concurrently. By enhancing the amount of Vusers, we can verify how much load the server can sustain.
