The source code is transformed by a compiler into bytecode, an intermediate language that connects high-level source code and low-level machine code. A unique kind of software called a compiler converts statements in source code into bytes, machine code, or another computer language. Lexical, s...
Socket programming is a technique for connecting two applications, or nodes, on a network by using sockets as endpoints for transferring and receiving data. It is a key networking concept that allows programs to communicate data over local and remote networks. In Python, the socket module contains...
A final class in Java is a concept of object-oriented programming where a class is declared using the "final" keyword. This type of class cannot be extended or inherited by other classes, making it inflexible. In this article, we will discuss the basics of the final class in Java, includ...
The Java bytecode is not completely compiled, but rather just an intermediate code sitting in the middle because it still has to be interpreted and executed by the JVM installed on the specific platform such as Windows, Mac or Linux. Upon compile, the Java source code is converted into the...
75% of the heap is live with objects from 128 bytes – 20 MB (humongous objects) If you’d like to follow along at home, here’s an example command line: jdk-17.0.2+8/bin/java-Xms80G-Xmx80G-Xlog:gc*,gc+ref=debug,gc+phases=debug,gc+age=trace,safepoint:file=<GC log file>-XX:...

bits. it can represent a single character, such as a letter, number, or symbol, in computer language. bytes are used to measure the size of computer files and storage capacity, with larger files requiring more bytes to store and transmit. what is the relationship between bites and file ...
HTTP request smuggling is a type of attack that exploits the difference in interpretation of a set of HTTP header values between two devices.
在引入 cache 之后,处理器访问主存首先通过 cache ,而 cache 与主存存取的单位通常为 1 cache line (通常为 64 Bytes) MMU 进行虚拟内存地址映射时,单位为 page (通常为 4 KiB)。例如0x10000虚拟地址映射到0xF0000, 指的是0x10000-0x1FFFF这连续的 1 page(假设为 4 KiB)地址空间映射到0xF0000-0xFFFFF。
