One-Pass CompilerOne pass compiler reads the code only once and then translates it. The one-pass compiler passes only once through the parts of each compilation unit. It can translate each part into its final machine program. In the one-pass compiler, when the line source is processed, it is scanned and ... Read More

Both compilers and interpreters are the language processors used to convert software codes written in high-level language into machine language codes. Compilers and interpreters are types of system software. They are required because a computer cannot process a code written in high-level programming language like C, C++, Java, etc. Therefore, ...

There are various classification of security attack is as follows − Cryptanalytic attacks These attacks are combination of statistical and algebraic techniques objective at make sure the secret key of a cipher. These technique inspect the numerical properties of the cryptographic algorithms and aims at discovering distinguishers of the output ... Read More

There are various applications of cryptography which are as follows − Secrecy in Transmission Some existing secrecy systems for transmission access a private key system for converting transmitted data because it is the quickest approach that functions with rational guarantee and low overhead. If the multiple conversing parties is minute, ... Read More

Cryptography is an automated mathematical tool that plays an important role in network security. It supports the confidentiality and integrity of information and provide authentication and non-repudiation to the users. Cryptography is frequently used in distributed applications to transfer recognition and authentication information from one system to another over a ... Read More

The physical layer meets all these requirements out. The set of rules and procedures for interaction between physical layers are called Physical layer protocols. The layer provides a physical connection different from the physical transmission path because it is at the bit level while the transmission path is at the ... Read More

Problem − Consider the following grammar − E → TE′ E′ → +TE′|ε T′ → FT′ T′ → FT′|ε F → (E)|id Solution − Step1− Elimination of Left Recursion & perform Left Factoring As there is no left recursion in Grammar so, we will proceed as it is. Also, there ... Read More

Computer registers are high-speed memory storing units. It is an element of the computer processor. It can carry any type of information including a bit sequence or single data.A register should be 32 bits in length for a 32-bit instruction computer. Registers can be numbered relies upon the processor design ... Read More

RSA is a cryptosystem for public-key encryption, and it is broadly used for securing sensitive information, specifically when being sent over an insecure network including the Internet.RSA algorithm is the most popular asymmetric key cryptographic algorithm depends on the mathematical fact that it is simply to discover and multiply large ...

Instruction includes a set of operation codes and operands that manage with the operation codes. Instruction format supports the design of bits in an instruction. It contains fields including opcode, operands, and addressing mode.The instruction length is generally preserved in multiples of the character length, which is 8 bits. When ... Read More
