What else can I help you with?
Why is it not possible to enforse memory protection at compile time?
Memory protection cannot be enforced at compile time because it relies on runtime information about how memory is accessed and used by a program. The compiler does not have complete knowledge of the runtime environment, such as dynamic memory allocation, pointers, or the interactions between different modules. Additionally, certain behaviors, like buffer overflows or access violations, may only become apparent during execution. Thus, enforcing memory protection requires mechanisms that operate at runtime, such as operating system support and hardware features.
How is protection affected in sgmentation of memory?
Protection in the segmentation of memory is protected by disallowing a process that is in use to access the memory of other processes that are not being used. It is a barrier between processes to protectÊthose not in use from possible virus infection or malicious software infection.
What do you do when the switch to remove write protection on a memory card does not work?
you should remove the contents if possible and reformat
What is compile-go loader?
compile and go loader is a type of loader function to have an assembler run in one part of the memory and places the assembled machine instructions,data as they are assembled,directly into their assigned memory location.
At what time the memory is allocated for variable in c and c?
Static memory allocation occurs at compile time where as dynamic memory allocation occurs at run time.
Is the write protection on usb memory card readers hardware or software write protection?
The write protection on the USB memory card readers is both a hardware and software protection.
What is the difference between static memory versus dynamic memory?
Dynamic memory can be declared at run-time using the new and delete operators (or malloc and free in C), while static memory must be declared at compile-time.
What does the write protection switch do on a Secure Digital memory card?
The write protection switch on the secure digital memory card helps prevent the accidental erasure of the data in the memory card.
When you compile source code where the variables stored?
When you compile source code, the variables are stored in memory during program execution. The compiler translates the source code into machine code, which allocates memory for variables in different segments, such as the stack (for local variables) and the heap (for dynamically allocated memory). The specific location and management of these variables depend on the programming language, the compiler, and the architecture of the system. Additionally, constants and global variables may be stored in separate memory regions.
How do you disable write protection on a memory card?
Adjust the switch on the memory card adapter
Does certain USB memory card readers support write protection for SD memory cards?
memory password forget
What is hardware protection mechanism in operating systems?
CPU protection Memory protection I/O protection Dual mode protection. Research more about these and maybe you will get where you are going.
