Pure and impure interpreters
In a pure interpreter, the source program is maintained in the source form throughout its interpretation. This arrangement acquires substantial analysis overheads when interpreting a statement.
An impure interpreter carries out some preliminary processing of the source program to decrease the analysis overheads during interpretation. The preprocessor transforms the program to an intermediate representation (IR) that is used during interpretation. This speeds up interpretation since the code component of the IR that is the IC, can be analyzed more resourcefully than the source form of the program.
What is the main function of the memory-management unit? The runtime mapping from virtual to physical addresses is done by a hardware device known as a memory management unit (
Explain Chaining to Handle Collision Chaining: One easy scheme is to chain all collisions in lists attached to the suitable slot. This permits an unlimited number of collision

Q. More than one disk drive is able to be attached to a SCSI bus. Especially a fast wide SCSI-II bus can be connected to at most 15 disk drives. Remember that this bus has a bandw
Hashed page table method A general approach for managing address spaces larger than 32 bits is to use a hashed page table with the hash values being the virtual-page number.
