The protection of memory allocated to one program from unauthorized access by another program is called memory protection. It may refer to protection among various programs in a multi tasking environment or in between OS and a program in a single tasking environment. It is needed to prevent a bug within a process from affecting other processes. It also prevents system crash in case of error on OS.
Memory allocation: When a program asks for memory and gets it.Contiguous allocation: When the memory is in one big block, for example memory addresses 1000-2000, as opposed to "fragmented allocation" where the memory comes as several smaller blocks in different places, for example memory addresses 1000-1050, 2050-2125, ...Memory protection: Normally some sort of limitation on who can write to which memory, to reduce the risk that a bug or a virus can damage data or bring down the computer.
if a variable is of value type memory is allocated on stack memory.. if it is of reference type,memory is allocated on heap memory..
functions of utility program is to perform specific tasks related to the management of computer functions,resources or files as password protection,memory management,virus protection and file compressionThis utility reads all V3 MMS output files, print out the header, partial sub-header and a value from all fields in the dataset.
the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU. the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU.
primary memory is built in memory on a computer it is the main type of memory.... eg RAM ROM and HDD
The write protection on the USB memory card readers is both a hardware and software protection.
The write protection switch on the secure digital memory card helps prevent the accidental erasure of the data in the memory card.
Adjust the switch on the memory card adapter
CPU protection Memory protection I/O protection Dual mode protection. Research more about these and maybe you will get where you are going.

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.

Removing write protection from a memory card is simple. Just insert it into the USB drive, and then double click on the flash drive icon when it pops up in the tray. Next, go to properties, and then click the checked box beside 'write protection.' That will remove the write protection from the drive.
