Decision Statements in VB .Net Definition A decision statement in VB .NET is used to control the flow of execution of a program statement by allowing different blocks of code to execute based on conditions or logical expressions. Need for Decision Statements Decision statements are required to: Make programs dynamic Read more…
Array Introduction An array in VB .NET is a simple and static data structure. Definition In VB .NET, an Array in VB .NET is a collection of elements of the same data type stored in contiguous memory locations and accessed using a single variable name with an index. However, if an array Read more…
Introduction of NFS It was originally developed by Sun Microsystems in 1984 and is widely used in UNIX/Linux systems. NFSv4.1/4.2 is the latest version of NFS. Definition of NFS Network File System (NFS) is a distributed file system protocol that allows a user on a client computer to access remote files over Read more…
Introduction File Transfer Protocol (FTP) is a standard network protocol used to transfer files between a client and a server over a TCP/IP network. Linux provides several FTP services that allow secure and efficient file sharing between systems. FTP Services in Linux Linux supports multiple FTP solutions or services, each Read more…
Introduction Software metrics and models play a crucial role in software engineering by providing measurable and objective information about software processes and products. Software metrics models enable better planning, control, and continuous improvement in software development. Definition Software metrics are quantitative measures used to evaluate, control, and improve the software Read more…
Machine Code Generation is the phase of a compiler where the intermediate code is finally translated into target machine code or assembly language. It involves:- Translating expressions: This step converts high-level arithmetic or logical expressions into machine instructions. Register allocation: This step chooses registers for variables to improve execution speed. Read more…
Code optimization aims to improve the intermediate code or machine code so that it executes faster, uses less memory, and consumes fewer resources. There are the following types of code optimization techniques:- Peephole Optimization This optimization looks at a small sequence of consecutive instructions and replaces them with more efficient Read more…
Intermediate Code Generation is a step in compiler design where the compiler converts high-level source code into an intermediate form that lies between the source code and the machine code. The main purpose of this intermediate code is machine independence, which allows the same front-end of the compiler to be Read more…
Introduction Semantic analysis is performed by the Semantic Analyzer. Definition Semantic analysis is the third phase of a compiler that verifies the semantic errors (undeclared identifiers, type mismatches, duplicate declarations, etc.) of the valid parse tree generated during the syntax analysis phase to ensure it is logically correct. Characteristics Semantic Read more…
