Chapter I. INTRODUCTION1. What is design mode?Design patterns are the core solutions that people use to solve similar problems and solve such problems. Design patterns are used to implement design reuse.2. Four elements of design patternName: Describes the problem, solution,

In the course of learning, I found it was actually quite interesting. gave a certain degree of confidence.

XML version of HTML 4.0.1 and named XHTML1.0. The main difference between XHTML1.0 and HTML4.01 is that it complies with the XML encoding provisions. This means that unlike regular HTML, all XHTML attributes must contain quotation marks.All elements must be closed. 6. Document type, DOCTYPE switch browser mode document type is a set of machine-readable rules. They define what is allowed in a particular version of XML or HTML, and what is not allowed. When parsing a Web page, the browser uses th

scoped than the custom variable, such as the shell environment variables acting on itself and its child process. In all Unix and Unix-like systems, each process has its own set of environment variables, and by default, when a process is created, it is explicitly specified in the process creation, and it inherits most of the environment settings of its parent process. The shell program also runs on the operating system as a process, and most of the commands we run in the shell will run as a chil

lower layer. Due to locality, writing back can significantly reduce bus traffic.The disadvantage is increased complexity.Another problem is how to deal with write Miss.Write allocation: load the corresponding lower-level block to the cache, and then update the cache block. The disadvantage is that each Miss will cause a block to be transferred from the lower layer to the cache.Non-write allocation: Avoid high-speed caching and write the word directly to the lower layer.Performance impact of hig

where the contents of the disk sector should be stored. The logical block number translates a sector address and then transfers the content to main memory without CPU interference, a process known as direct memory access. This data transfer is called DMA transfer. When the volume of a disk sector is securely stored in main memory, the disk controller notifies the CPU by sending an interrupt signal to the CPU.

I recently read the design model. I like this book very much, and the content is also very understandable. I am a little addicted to reading it. Haha, I first looked at the object-oriented basics. I have been familiar with object-oriented basics before, I have a further understanding of the three features of object-ori

layer and find it in the cache content at the K layer. You can directly read data at the K layer, which is called cache hit. Cache miss. No data is found at the K layer. The cache at the K layer needs to retrieve the block containing objects from the cache at the K + 1 layer. If the K layer is full, overwrite an existing block. Cool hit, the K layer has nothing, so it does not hit. High-speed cache memory, mainly the size (p426) and probability (p431)Summary of test errors last week 2018-201

Today, the basic program design courses of the next younger brother and sister will be held in the summer, and the daily time is up to 8 hours. Let's look back at the dilemma of getting started programming, if you are free of charge, you will be added later. I hope it will be helpful to you. If you have any questions about C ++, please contact QQ (414445050) or email (qq mailbox) In those years, I learned the bas
