Lenovo ThinkPad z60t Review (PICs, Specs)
That's not an exhaustive list, but covers the major brands. if you don't care whether your laptop is widescreen or standard screen then the amount of notebooks available proliferates, the ThinkPad T43 is of course available as a 14 "standard screen and alternative buyers might end up being unsure of whether to go with the z60t or T43 14" if they want a thin-and- light ThinkPad, but don't care what the screen

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization.
The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling
The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall

Asynchronous Io is an essential feature of modern operating systems. It makes valuable CPU computing resources not wasted waiting for slow Io. Its behavior is intuitive. after sending an IO request, the user thread do
each block device or partition of a block device has its own request queue (request_queue), and each request queue can select an I/O Scheduler to coordinate the request submitted . The basic purpose of the I/O Scheduler is to arrange requests according to the sector code they correspond to on the block device to reduce the movement of the heads and improve efficiency. Requests in the request queue for each device are responded to in order. In fact, in addition to this queue, each scheduler itse
