In the first two sections, we loaded a piece of code into system memory through a floppy disk, and instructed the CPU to execute the code that was added to the memory, in fact, the operating system kernel was loaded. But we load the code, the maximum can only be a byte, an operating system kernel, less than hundreds of trillion, thus, the system kernel can not directly read into the system memory from the floppy disk.As a general rule, a program of bytes loaded into memory is actually a kernel l

Otherwise, the damage to the hard disk will be accelerated after dust enters. In addition, the track-seeking servo motor of the hard drive head mostly uses the audio ring rotation or linear motion stepping motor to precisely track the track of the disc under the adjustment of the Servo Tracking, whe

Basic Structure of Automobile
Modern cars are composed of multiple devices and mechanisms. The basic structure of vehicles produced by different models, types, and manufacturers is composed of four parts: Engine, chassis, electrical equipment, and body.(1) Engine
An engine is a device that powers an automobile. Its role is to make fuel combustion generate power, and then drive the car through the chassis drive whee

The hard disk is 80 GB, with 255 magnetic surfaces; 63 sectors; 9729 magnetic columns; the capacity of each cylinder (magnetic column) is 8225280 bytes = 8225.280 K (about) = 8.225280 M (about );

of a card. Most mature accurate cards are built on the preliminary concept.(2) Order of cards from other companiesWe have already mentioned this in the "control the next house" section. We should remember the order of cards played by another house at any time, and we can guess-why did he play that one first and then this one? It makes sense.For example, you can create two bins at home and then four at home. He may have split the building; he may have caught a pair of five cylinders while four c

Second, the working principle of hard disk
The hard disk is logically divided into tracks, cylinders, and sectors.

Each side of each platter of the hard disk has a read and write head, and the partition of the disk surface area is shown in the figure.

Currently, many open-source cross-platform software are available, which makes the performance of Linux and Windows software comparable. mongomed Saleh made a Ubuntu 8.04 (download) and Windows XP SP3 (download) software performance comparison.
The test mainly includes multimedia performance and hard disk performance. The former is mainly used to test the performance of software such as blender (download) and avidemux (download, the latter mainly uses

When people use a computer, sometimes because of abnormal operation, sometimes because of virus attack, can cause a partition to disappear or hard drive cannot start. The reason is that the hard disk partition table is damaged. The hard disk partition table can be said to support the hard disk normal work skeleton. It is the operating system that divides the hard disk into partitions, and then creates the file system in each partition and writes the data file. This article is mainly about the lo
