Operating System

The invention of the _________ was the hardware revolution that brought about desktop and handheld computing.

Answer explanation

Microprocessor and multiprocessors belong to processor.

Processor is component of OS. Operate system contain:

• - Processor

• - Main memory

• - I/O modules

• - System bus

• Microprocessor: each chip(socket) contain a processor(socket)

• Multiprocessors: chip contain multiple processors

To satisfy the requirements of handheld devices, the classic microprocessor is giving way to the _________ , where not just the CPUs and caches are on the same chip, but also many of the other components of the system, such as DSPs, GPUs, I/O devices and main memory.

Answer explanation

To satisfy the requirements of handheld devices, the classic microprocessor is giving way to the SoC

The processing required for a single instruction is called a(n) __________ cycle.

Answer explanation

Instruction cycle quá trình xử lý lệnh là quá trình xử lý cần thiết cho một câu lệnh duy nhất.

The fetched instruction is loaded into the __________ .

Answer explanation

Fetched instruction is loaded into Instruction Register (IR)

lệnh sau khi được nạp sẽ được tải vào thanh ghi lệnh

Program counter là chương trình đếm lệnh nạp nó cộng thêm sau mỗi lần lệnh được nạp

Program counter hold address of fetched instruction.

When an external device is ready to accept more data from the processor, the I/O module for that external device sends an __________ signal to the processor.

Answer explanation

I/O module is intermediate between Processor and external devices

I/O move data between processor and external devices.

The __________ is a device for staging the movement of data between main memory and processor registers to improve performance and is not usually visible to the programmer or processor.

Answer explanation

cache bộ nhớ đệm là đơn vị bộ nhớ nhỏ và nhanh hơn, là một loại bộ nhớ volatile.

cache as an intermediary between CPU and main memory.

External, nonvolatile memory is also referred to as __________ or auxiliary memory.

Answer explanation

Secondary memory: or auxiliary, nonvolatile, external

used to store program and data files.

When a new block of data is read into the cache the __________ determines which cache location the block will occupy.

Answer explanation

Mapping Function Determines which cache location the block will occupy

Mapping -> location

In a _________ multiprocessor all processors can perform the same functions so the failure of a single processor does not halt the machine.

Answer explanation

Symmetric Multipleprocessors: a stand-alone computer system:
- All processors can perform the same function

• - Processors share the same main memory

A __________ computer combines two or more processors on a single piece of silicon.

Answer explanation

multicore computer = chip multipleprocessors

chip= socket, core = processor

Ta nói một máy tính đa core hay có thể gọi là chip đa bộ xử lý.

multicore computer combines 2 or more processors on a single piece of silicon.
