What is the maximum integer allowed in an integer-type variable?
That varies from each programming language. As a matter of fact, many languages do not put a limit on the maximum size of a variable. It will handle any string, integer, resource, pointer, or other type size, as long as it fits into the memory of the machine running the process.
What is memory allocation?
Memory allocation is the act of reserving a chunk of memory for some set of data. In programming terms, this is normally done by declaring a variable. Large arrays of data will require large blocks of contiguous memory, which the programmer must request from the operating system.
What are types of memory allocation?
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
What Linked list uses.type of memory allocation?
Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).
How many values can store a variable at a time?
The number of values a variable can store at a time depends on the data type of the variable. For example, a variable of type int (integer) in many programming languages can store a single integer value at a time. Similarly, a variable of type float (floating-point number) can store a single floating-point value. Other data types like arrays or lists can store multiple values at a time. The capacity of a variable to store values is determined by its data type and memory allocation.
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.
How is partitioned allocation different from relocatable partitioned allocation?
Partitioned allocation is a fixed memory allocation technique which memory spaces are divided into smaller fixed partition, while Relocatable partitioning use variable and repartitioning technique
What is meant by contiguous memory allocation in C?
Contiguous memory allocation in C programming refers to the assigning of consecutive memory blocks to a process. Contiguous memory allocation is one of the oldest and most popular memory allocation schemes in programming.
Which of the follwing gives the memory addrees of integer variable a?
The memory address of an integer variable a can be obtained using the address-of operator & in languages like C or C++. For example, using the expression &a will yield the memory address where the variable a is stored. This address is typically represented in hexadecimal format.

What is heaped?
The heap is a section of memory controlled by a program used for dynamic variable allocation. Heap size is the size of that section of memory.

What is the difference between contiguous and non contiguous memory allocation?
in contiguous allocation overhead during execution of a program.in non contiguous allocation address translation is performed during execution of a program..
What is the comparison between paged memory allocation and paging memory allocation?
Paged memory allocation and paging memory allocation essentially refer to the same concept in modern operating systems, where memory is divided into fixed-size blocks called pages. Paged memory allocation allows the system to manage memory more efficiently by loading only the necessary pages into physical memory, which helps prevent fragmentation. In contrast, paging memory allocation focuses specifically on the method of mapping virtual addresses to physical addresses using a page table. Both techniques aim to optimize memory use and improve process isolation and performance.
What is segmented page allocation?
Segmented page allocation is a type of memory management that uses base and bound registers to determine memory faults, similar to dynamic page allocation. More importantly it is different to dynamic page allocation since the entire process doesn't have to be in memory, similar to using virtual memory paging where the program is broken into pieces. Unlike virtual memory paging, the maximum virtual memory size is limited to the size of physical memory.
Compare and contrast dynamic memory allocation and the allocation of files in secondary storage?
Static Memory Allocation: Allocating the total memory requirements that a data structure might need all at once without regard for the actual amount needed at execution time. Dynamic Memory Allocation: The opposite strategy of static memory allocation - Dynamic Memory Allocation, involves allocating memory as-needed.
