Quantum figuring contemplates hypothetical calculation frameworks (quantum PCs) that make coordinate utilization of quantum-mechanical marvels, for example, superposition to perform operations on data. Quantum PCs are unique in relation to binary digital PCs in light of transistors.While regular advanced registering requires that the information is encoded into twofold digits (bits), each of which is dependable in one of two distinct states (0 or 1), quantum calculation utilizes quantum bits, which can be in superpositions of states. A Quantum Turing Machine is a hypothetical model of such a PC and is otherwise called the general quantum PC.What are they?Starting at 2017, ... Read More

Python is a scripting language while C is a programming language. C/C++ is relatively fast as compared to Python because when you run the Python script, its interpreter will interpret the script line by line and generate output but in C, the compiler will first compile it and generate an output which is optimized with respect to the hardware. In case of other languages such as Java and.NET, Java bytecode, and .NET bytecode respectively run faster than Python because a JIT compiler compiles bytecode to native code at runtime. CPython cannot have a JIT compiler because the dynamic nature of ... Read More

When you develop a web application, before hosting to the web, testing is very important to prevent the hackers. There are three types of tests, Black, gray and white box tests which are conducted to ensure that an attacker cannot reach your application code.White Box (or glass box) testingWhite Box (or glass box) testing is the process of giving input code to the system and checking how the system processes it how the output is generated using that code. This is the test where the team tests the internal logic of the code written.It is the process of checking how ... Read More

The 8085 is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology that can address 64K Byte of memory. It has 40 pins DIP (Dual Inline Package) IC.In bellow fig, the pin number, and its associated functions are indicated for each of the 40 pins:Data pinsAD7-0 are known as data pins and carries lower order address bits of memory and  I/O Address. These pins are bi-directional pins. The same lines are used for both receiving information and sending out information because, at any instant of time, the processor is either receiving or sending out information, but not both.Address pinsA15-8 ...

The sign-magnitude binary format is the simplest conceptual format. In this method of representing signed numbers, the most significant digit (MSD) takes on extra meaning.If the MSD is a 0, we can evaluate the number just as we would any normal unsigned integer. And also we shall treat the number as a positive one.If the MSD is a 1, this indicates that the number is negative.The other bits indicate the magnitude (absolute value) of the number. Some of the signed decimal numbers and their equivalent in SM notation follows assuming a word size of 4 bits.Signed decimalsign-magnitude     +6   0110    ... Read More
