What is techniques of storage allocation in compiler design?
There are various storage allocation techniques are as follows −Static AllocationIt is the simplest allocation scheme in which allocation of data objects is done at compile time because the size of every data item can be determined by the compiler.Recursive Subprogram and Arrays of adjustable length are not permitted in a language. In static allocation, the compiler can decide the amount of storage needed by each data object. Thus, it becomes easy for a compiler to identify the address of these data in the activation record.FORTRAN uses this kind of storage allocation strategies.AdvantagesIt is easy to implement.It allows type checking ...
Read MoreHow to get environment variable value using PowerShell?
Environment variables are an essential part of the Operating System. They store various information like the path of the system files and folders, the number of processors system running, current user details, and more. Processes and programs utilize these environment variables to retrieve the data for their execution.Environment variables in PowerShell are stored as PS drive (Env: ). To retrieve all the environment variables stored in the OS you can use the below command.Get-ChildItem -Path Env:Name Value ---- ...
Read MoreOne’s Complement
Binary Number System is one the type of most popular Number Representation techniques that used in digital systems. In the Binary System, there are only two symbols or possible digit values, i.e., 0 (off) and 1 (on). Represented by any device that only 2 operating states or possible conditions.Generally, there are two types of complement of Binary number: 1’s complement and 2’s complement. To get 1’s complement of a binary number, simply invert the given number. For example, 1’s complement of binary number 110010 is 001101. To get 2’s complement of binary number is 1’s complement of given number plus ...
Read MoreHow to Convert Decimal to Hexadecimal?
Decimal system is most familiar number system to the general public. It is base 10 which has only 10 symbols − 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Whereas Hexadecimal system is most familiar number system color representation in Computers or digital systems. It is base 16 which has only 16 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F. These A, B, C, D, E, F use as single digit in place of double digits, 10, 11, 12, 13, 14, 15 respectively.Conversion from Decimal to Hexadecimal ...
Read MoreDifference between Intrinsic and Extrinsic Semiconductor
Semiconductor devices are extensively used in the field of electronics. A semiconductor is a substance whose resistivity lies between conductors and insulators. Semiconductors have negative temperature co-efficient. The resistance in semiconductors increases with the decrease in temperature and vice versa. The conducting properties of a semiconductor changes, when a suitable metallic impurity is added to it.In this article, we will highlight the major differences between intrinsic and extrinsic semiconductors by considering different parameters such as doping level, conductivity, charge density, etc.What is an Intrinsic Semiconductor?A semiconductor material in its pure form is known as an intrinsic semiconductor. Thus, the intrinsic ...
Read MoreWhat are the Factors Affecting Consumer Behaviour?
What is Consumer Behavior?Consumer behaviour is the study of how individual customers, groups or organizations select, buy, use, and dispose ideas, goods, and services to satisfy their needs and wants. It refers to the actions of the consumers in the marketplace and the underlying motives for those actions.Engel, Blackwell, and Mansard define consumer behaviour as “…the actions and decision processes of people who purchase goods and services for personal consumption.”Factors Affecting Consumer BehaviorConsumer Behaviour is influenced by many different factors. The five major factors that influence consumer behaviour are as follows −Psychological FactorsHuman psychology plays a major role in understanding ...
Read MoreFixed Point and Floating Point Number Representations
Digital Computers use Binary number system to represent all types of information inside the computers. Alphanumeric characters are represented using binary bits (i.e., 0 and 1). Digital representations are easier to design, storage is easy, accuracy and precision are greater.There are various types of number representation techniques for digital number representation, for example: Binary number system, octal number system, decimal number system, and hexadecimal number system etc. But Binary number system is most relevant and popular for representing numbers in digital computer system.Storing Real NumberThese are structures as following below −There are two major approaches to store real numbers (i.e., ...
Read MoreHow to recover YouTube Channel?
When you mistakenly delete or lose access to your YouTube channel at some point in your life, you want to retrieve your previous YouTube account. Whatever the reason, this behavior will have a host of repercussions, particularly if you attempt to trademark your company or yourself. As a result, we have put together this guide on rebuilding your YouTube account and some hints for you to help alleviate these issues. Why Does YouTube Channel Delete Accidentally? Violates Guidelines and Copyright issues − There are standards for posting material, photos, captions, hashtags, and other things on every online platform ...
Read MoreDifference between Active and Passive Components (in Electronics)
In electrical and electronics engineering, the closed path followed by the electric current is known as electric circuit. Every electric circuit is composed of many circuit components such as sources of power, resistors, capacitors, inductors, diode, etc. Therefore, the circuit components are the basic building blocks of an electrical or electronic circuit.Depending upon the power delivering or absorbing ability, the circuit components can be classified in following two types −Active componentsPassive componentsThe most significant difference between active components and passive components is that an active component can supply power to an electric circuit, whereas a passive component cannot deliver power, ...
Read MoreThree Level Architecture of Database
The ANSI-SPARC database architecture is the basis of most of the modern databases.The three levels present in this architecture are Physical level, Conceptual level and External level.The details of these levels are as follows −Physical LevelThis is the lowest level in the three level architecture. It is also known as the internal level. The physical level describes how data is actually stored in the database. In the lowest level, this data is stored in the external hard drives in the form of bits and at a little high level, it can be said that the data is stored in files ...
