What are machine dependent and machine independent features?
January 2018) (Learn how and when to remove this template message) Machine-dependent software is software that runs only on a specific computer. Applications that run on multiple computer architectures are called machine-independent, or cross-platform.
Which one of the following is machine independent?
Answer: A Machine Independent language is one that can run on any machine. An example of this would be Java. Because of the Java Virtual Machine or JVM it can take the compiled code for any given Java App and run it on the machine you are attempting to run it on.
What is a bootstrap loader explain?
A Bootstrap Loader (BSL) is a small program which can be activated immediately after a microcontroller has been powered up, in order to load and execute another program in a well defined manner. No need to open the device’s housing, or replace the program memory chip.
What is relocation in system programming?
Relocation is the process of connecting symbolic references with symbolic definitions. For example, when a program calls a function, the associated call instruction must transfer control to the proper destination address at execution. This member gives the location at which to apply the relocation action. …
