WHAT IS SINGLE USER CONTIGUOS SCHEME?
Single user contiguous scheme is a memory allocation technique where a single block of contiguous memory is allocated to a process. This means that the entire memory space needed by a process must be available in a single block without any breaks or fragmentation. It simplifies memory management but can lead to wastage of memory due to fragmentation.
Difference between contiguous and non contiguous memory?
In contiguous allocation there is no overhead during execution of a program. In noncontiguous allocation address translation is performed during execution Contiguous memory allocates single area of memory Noncontigious memory allocates several memory areas - one memory are to each component of a process
Compare Contiguous memory allocation with internal fragmentation?
in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!
What is the difference between contiguous and noncontiguous text?

What are some of the benefits of using an array as opposed to a medium-sized list of variables?
Arrays exist in contiguous memory, so you can use simple pointer arithmetic to access any element by its offset from the start address (the array name is an alias for the start address), and can pass the entire array to functions as a single entity. Lists of variables are not guaranteed to exist in contiguous memory, and cannot be passed to functions as a single entity.
What are the different between array and variables?
A variable is a reference to a single object (often a number, character, or string of characters). An array is a reference to a contiguous block of memory in which zero or more individual objects.
What are the linked list utility in memory management?
A simple linked-list is an approach is to store the freelist of memory blocks, where each node of the linked list contains a pointer to a single free block in the memory pool.
What does 80486 microprocessor from Intel consist of?
It contains a 32 bit CPU, a floating-point math coprocessor, unified instruction and data cache memory and memory management unit in a single IC.
What is the real estate definition of Floor contiguous?
Contiguous Space: Multiple suites/spaces within the same building and on the same floor which can be combined and rented to a single tenant.
What is the advantage of a single fixed pulley?
a directional advantage
What is a single and double sided memory?
Single-sided memory has memory chips on only one side of the module, while double-sided memory has memory chips on both sides. Double-sided memory typically has a higher memory capacity than single-sided memory due to more chips being present.
