What is partition? Partitioning refers to telling the operating system that the disk is divided into several partitions by the cylindrical range. For example, 1-50 cylinders are used as sda1, and 51-cylinder are used as sda2 partitions. In this way, a hard disk (or lun) is divided into smaller and better management units. Next we can format different partitions into different file systems.What is formatting? What is the purpose of formatting a partiti

Sectors Available Note: Why fail in failure? Note: I am trying to add a primary partition, it seems to be a failure, why fail? Because we see the primary partition + extended partition run out of the entire disk, look at the extension of the end of the partition, and then look at the P output information has a cylinders; it's best to look at the previous part; So we can only add logical partitions.

expected Frame Rate and resolution. The CPU is responsible for the frame rate, while the GPU is mainly responsible for the resolution. To sum up, the main performance bottleneck lies in: CPU Too many Draw CILS Complex script or physical simulation Vertex Processing Excessive vertices Excessive vertex-by-vertex Computation Fragment Processing Excessive fragment and overdraws Excessive pixel-by-pixel computing Bandwidth

Coordinate system and basic elements (1) Direct3d Basic Elements Primitives is a basic graphic representation defined in direct3d. It is a set of vertices that constitute a single object. The simplest element is a set of multiple vertices in a three-dimensional coordinate system. It is called a point list ). A polygon is a polygon. A polygon is a closed graph composed of at least three edges. The simplest p

process of running the program. It is also called Run-time polymorphism. Dynamic polymorphism is realized through virtual function (virtual fiinction). Here is an example of a connecting link. On the one hand, it is an example of an integrated application of inheritance and operator overload content, which can be used to further integrate what has been learned earlier, and, on the other, as a basic use case for discussing polymorphism. I hope you will patiently and thoroughly read and digest

installing Swift 3D V4, start the program and click the Advanced Modeler tab to switch to the Advanced Modeler workspace, with a editing mesh (edit grid) button on the right side of the toolbar, and if not, press this button. 2, we use cylindrical body as the original object of making coffee cup. Click on the Create Cylinder mesh (Create cylinder grid) button on the main toolbar, where the

following is the square just we set the red material resources, shader set the properties of the map, is currently gui/textshader. It indicates that the rendering level of this material is on the GUI, which is the first level of precedence. For example, no matter how many models are drawn in front of the grid model, it will always be displayed first. For this example, its existence is not necessary, in fact, there are many options shader, transparent, non-transparent, mirror, reflection and so

source node, each subsequent to find a shortest path, the corresponding vertex is added to the set S, until all the vertices are added to the s) The second group is the vertex set of the indeterminate shortest path U. During the join process, the shortest path length that is always maintained from the source node V to the vertices in S is less than the shortest path length from the source node V to any ver

. In order to take into account the knowledge integrity, or simply do a brief introduction, interested students can go to the Internet to find the keyword CHS. The earliest hard disk has multiple platters, each with a head (head) to scan it, a platter divided into concentric rings, each of which is called a track, and each track is divided evenly into multiple arcs called sectors (Sector). It is important to note that the concentric rings here, regardless of radius, are divided into the same num

, information is recorded in these tracks in the form of a pulse string. These concentric circles are not recorded continuously, but are divided into arcs of the segment. The angle velocity of these arcs is the same. Because the radial length is different, the line velocity is also different. The line velocity of the outer ring is higher than that of the inner ring. That is, the outer ring is in the same time period at the same speed, the length of the arc to be crossed is larger than that of th

important role. MBR (Master Boot Record), which is also known as the Master Boot Sector. Located in the entire hard disk, the 0-cylinder, 0-head, and 1-sector (which can be regarded as the first sector of the hard disk). After the BIOS executes its own program, it will jump to the first instruction in MBR. Control of the system is handed over to MBR for execution. In the master boot records of a total of 446 bytes, the MBR boot program occupies the f
