Spatial Computing Basics, Working, Advantages, Disadvantages and Applications
What is Spatial Computing? Spatial computing is a technological field that combines components of physical world and computer science to create a user interface which is more immersive and interactive. Spatial computing involves the tools and processes to record and process the three-dimensional data. The major elements of spatial computing include the advanced technology tools like virtual reality (VR), augmented reality (AR), mixed reality (MR), IoT, artificial intelligence (AI), physical controls, etc. All these components combine the digital systems and physical world together. Fundamentally, spatial computing uses technology that understand and interact with the world in spatial terms. Spatial computing ...
Read MoreBlue Screen of Death (BSOD) in Windows and its Common Stop Error Codes
What is the Blue Screen of Death? Blue Screen of Death (BSOD) is an error screen which displayed due to driver error or hardware failure in a Windows OS based computer system. It is called BSOD because it is one of the critical system errors at the Windows Kernel level. Hence, the system cannot be recovered from it. The following picture depicts a Blue Screen of Death (BSOD) with a stop error code “CRITICAL_PROCESS_DIED”. Whenever the Blue Screen of Death error occurs, the system stops working and a blue screen is displayed with an error message. The error message ...
Read MoreBasic Computer Instructions in Computer Organization
In computer organization, a computer instruction is a set of commands that tells the computer hardware to perform a specific operation. Therefore, computer instructions are the primary building blocks of a computer program and hence a software, because computer instructions are entirely responsible for execution of the program or software. In this article, we will learn the basic computer instructions in computer organization. The format in which the computer instructions are to be written is defined by the instruction set architecture (ISA) of the computer. The instruction set architecture defines the set of instructions that are supported by the processor ...
Read MoreScheduling with Deadline
Within the field of computer science, productive task scheduling plays a pivotal part in optimizing resource allocation and assembly time constraints. Scheduling with deadlines is a principal concept that spins around allocating tasks or processes to resources while considering time limitations or deadlines. The objective is to ensure that tasks are completed within their assigned time limits, minimizing lateness, and ensuring timely execution. This article explores the concept of scheduling with deadlines in computer science, its significance in different spaces, and the approaches and procedures utilized to meet time constraints. It dives into the challenges related to scheduling tasks within ...
Read MoreDifference between System Call and Library Call
In computer programming, system calls and library calls are essential mechanisms used to interact with the underlying operating system and perform various operations. While they both involve invoking functions or routines, there are distinct differences between system calls and library calls. Understanding these differences is crucial for developers to efficiently utilize these mechanisms in their applications. This article explores the dissimilarities between system calls and library calls, shedding light on their respective characteristics and functionalities. What is System Call? A system call is a mechanism provided by the operating system that allows user-level programs to request services from the operating ...
Read MoreDifference between Firmware and Operating System
A Firmware is a set of instructions or a block of code that is programmed in hardware devices. It instructs the hardware to perform its function when the call is made. Firmware is present in computers and electronic devices. Operating system is a software that sits in between the software and hardware of the computer system. It acts as a mediator and provides the interface to interact with them. Operating systems are used in computers, laptops, TV, mobiles, etc. What is a Firmware? A Firmware is a small code embedded in the hardware. They are modified software versions. The ...
Read MoreDifference between Encoder and Decoder
A combinational circuit is one that contains logic gates. Encoders and decoders are such combinational circuits in which one changes the input data into binary code and the other one decodes it to its original input signal. Both encoders and decoders are multiple input and multiple output devices Encoding allows the input signal to function on various systems. For instance, when we search something in the web browser, it is converted into a binary code (encoding) which can be understood by it then search for it and send the results back to the user by converting the binary form into ...
Read MoreDifference Between Keyword and Identifier
Every programming language has keywords and identifiers. Both keywords and identifiers can be processed by a compiler, however they are quite different from each other. The basic difference between the two is that keywords are the reserve words which are predefined and have a special meaning in the language, whereas an identifier is a unique name assigned to a variable, function, class, etc. Read this article to learn more about keywords and identifiers and how they are different from each other. What is a Keyword? Keywords are reserved words that have a special meaning in a programming language. Therefore, we ...
Read MoreDifference Between Identifier and Variable
An Identifier is a name assigned to an entity in a computer program so that it can be identified distinctly in the program during its execution. On the other hand, a variable is a name assigned to a memory location that stores a value. Read this article to learn more about identifiers and variables and how they are different from each other. What is an Identifier? Identifiers are used to name a variable, a function, a class, a structure, a union. In other words, an identifier is created to give a unique name to an entity. It can consist of ...
Read MoreDifference between Header file and Library
In C, C#, Java or any other programming language, both header files and libraries provide some specific APIs and their functionality to be used in the main file. Both the header file and the library are combined and used as a single unit. But, on the basis of nature of files, we can distinguish between a Header File and a Library. Read this tutorial to learn more about header files and libraries and how they are different from each other. What is a Header File? The file that contains all the header names which are to be used in the ...
