36. What is translation lookaside buffer (TLB) ?
A translation lookaside buffer is a memory cache that is used to reduce the time taken to access a user memory location. It is a part of the chip’s memory-management unit. The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache.

37. What is Operation Code ?
Operation Code, which is the part of an instruction in machine language to specify the operation to be performed. A complete machine language instruction consists of an opcode and zero or more operands with which the specified operation is performed.

38. What is Rambus Dynamic Random Access Memory (RDRAM) ?
Rambus Dynamic Random Access Memory (RDRAM) is a memory subsystem designed to transfer data at faster rates. Typical SDRAM has a data transfer rate of up to 133 MHz, while the RDRAM can transfer data at a speed of upto 800 MHz. RDRAM is also known as Direct RDRAM or Rambus.

39. What is the process of routing ?
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. … Packet forwarding is the transit of network packets from one network interface to another. Intermediate nodes are typically network hardware devices such as routers, gateways, firewalls, or switches.

40. What is instruction set architecture (ISA) ?
The instruction set architecture (ISA) is a protocol that defines how a computing machine appears to a machine language programmer or compiler. The ISA describes the (1) memory model, (2) instruction format, types and modes, and (3) operand registers, types, and data addressing.
