Which memory storage system seems to last indefinitely?
fixed memory
What is the difference between fixed and variable partition?
in the fixed partition the partition is once allocated is fixed. in fixed partition more memory wastage because of internal & external fragmentation.... in variable partition when a process comes then according to need of process the size of memory is allocated to the process
Does jailbreaking the itouch make infinite memory space?
An ipod's Hard drive/flash memory is fixed.
What does absolute address mean?
It is the fixed location of computers memory
What is fixed partition main memory management technique in operating systems?
A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time. The main memory (which is the volatile memory where active programs and data are held during use), is divided into partitions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run. So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size. And a process is loaded into a partition big enough to hold it.
Difference between fixed partition and dynamic partition in memory management?
Fixed partitions have fixed size and usually cannot be easily expended or shrunk. Dynamic partitions can change size by themselves when they need it. There are some advantages of using fixed partitions because you control its size. It might happen that you can run out of free space when you are using dynamic partitions.
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 a fixed read-write head?
A fixed read-write head is a type of hardware in a computer. It is the sub-section of the optical or hard disk used for storing a specific amount, or fixed amount, of memory.
What the advantages and disadvantages of using variable length instructions?
. fixed-length instructions · advantage: fixed-length instruction is fast and results in better performancewhen instruction levelpipelining is used. · Diadvantage: wastes space b. variable-length instructions · Advantage: Variable-length instruction saves storage space/ · Disadvantage: more complex to decode
Is the root directory of a disk should be placed at a fixed address in main memory?
NO.. it can be at any address in main memory.. But is should be at fixed location on hard disk because root directory needs to be loaded every time the pc boots.. thus it is kept at fixed location in disk to avoid the searching for it at every boot
