solidity memory vs storage

The structure of the storage of these several, has long been clear on the chest. But recently the actual operation, suddenly feel not so know it, simply in turn out to see, is a kind of experience. The general called "stack" in data structure is a kind of last-in-first-come-out. It is a concept, or a logical technique, that is independent of language and platform.The "Stacks" in memory management are actual

classes. That is to say, the basic principle of Slab allocator is to divide the allocated memory into blocks of a specific length according to the predefined size, To completely solve the memory fragmentation problem. The principle of slab allocation is quite simple. Split the allocated memory into chunk blocks of various sizes, and split the chunk blocks with t

Storage Class of local variables and global variables in C Language (static, extern, auto, register) 1. Local and global variablesAs mentioned in the discussion of the parameter variables of a function, the parameter variables are allocated memory units only during the call period, and are released immediately after the call ends. This indicates that the parameter variable is valid only within the function

frame for the thread method (which can be understood as a storage area in the JVM stack space). This stack frame is used to store local variable tables, operand stacks, dynamic links, and method entry information.Java memory is often differentiated into heap memory (heap) and stack memory (stack), which is coarser, an

Label: style blog color ar use SP data Div on 1. Preface In code writing, we often call back one method or another (function). But do we know how to allocate various parameter types in memory? Not necessarily. At least I didn't know much about it before. We may think that this is only a small problem. We feel that we can only know what the method is and call the method, so we ignore this. The following describes how the parameters in the method are a

memory allocation of the program In a computer system, the data that runs the application is stored in memory, different types of data, and the memory areas that are saved are different, including:1. Stack area [stack]: Automatically allocated by the compiler release, store the function parameter value, local variable value and so on. It operates in a manner simi

, you need to make large-scale memory release so that the process can run, and secondly, in physical memory, the different processes are "visible", That is, a process can "access" other processes in some way, which creates a tremendous degree of insecurity. Virtual memory/Virtual storage can be said to solve the above

Storage Method of floating point and floating point in memory, floating point First, let's talk about how to convert decimal places to binary decimal places. The computer doesn't even know the decimal data. He only knows 0 and 1. So, decimal decimal places are represented by binary decimal places in the computer. Decimal decimal to binary decimal: It can be simply summarizedReturns an integer in the positiv

Future Review We learned earlier that the byte sequence of data storage differs depending on the schema of the CPU's End mode Be Big-endian big-end mode , the most intuitive byte-order address low storage value of high, address high storage value of low , data filling, do not consider the corresponding relationship, just to the

It is clear that the binary representation of decimals is sometimes impossible to be precise. In fact, the reason is very simple, decimal system

The following articles mainly describe the actual application of Process Memory in the Oracle storage structure. We all know the actual application processes of Oracle except for the SGA (System Global Area, the following three global zones are also frequently used: The Process Global Area (PGA ); The User Global Area (UGA ); The Call Global Area (CGA ). Many people do not know the difference between PG
