During the <u>design</u> phase of system development, you would acquire all the necessary hardware and software.
<h3>What is SDLC?</h3>
SDLC is an abbreviation for system development life cycle and it can be defined as a strategic methodology that defines the key steps, phases, or stages for the design, development and implementation of high quality systems.
In Computer technology, there are seven (7) phases involved in the development of a system and these include the following;
Also, phased implementation simply refers to an implementation methodology in which smaller portions of functionality of a system are typically implemented one at a time (one after the other).
In conclusion, we can infer and logically deduce that you would acquire all the necessary hardware and software during the <u>design</u> phase of system development.

Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item
<h3>What is Parameter variable?</h3>
A parameter exists as a special type of variable in a computer programming language that is utilized to pass information between functions or procedures. The actual information passed exists called an argument. A parameter exists as a named variable passed into a function. Parameter variables exist used to import arguments into functions.
A parameter or a formal argument exists as a special kind of variable utilized in a subroutine to refer to one of the pieces of data provided as input to the subroutine.
The call-by-value process of passing arguments to a function copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function maintain no effect on the argument. By default, C++ utilizes call-by-value to pass arguments.
Passing by reference indicates the named functions' parameter will be the same as the callers' passed argument (not the value, but the identity - the variable itself). Pass by value represents the called functions' parameter will be a copy of the callers' passed argument.
Hence, Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item
