Difference between Impact and Non-Impact Printers
A printer is an output device that produces information or computer outputs on a paper. Depending upon the technology used, printers are classified into two categories namely, Impact Printers and Non-Impact Printers. An impact printer is one that operates by striking a printing head (made up of metal or plastic) against an ink ribbon, whereas a non-impact printer is one that prints characters and graphics without direct physical contact between the printing head and the paper. Read this tutorial to find out more about Impact and Non-impact Printers and how they are different from each other. What is an Impact ...
Read MoreDifference between Holography and Photography
The primary difference between holography and photography is that holography is a technology used to create three-dimensional (3D) images of an object, whereas photography is one that creates two-dimensional (2D) images of a three-dimensional object. Read this tutorial to find out more about Holography and Photography and how they are different from each other. What is Holography? Holography is a technique to generate 3-dimensional images using interference and diffraction of light. It uses a coherent and monochromatic source of light. A hologram is needed to regenerate an image. In other words, holography can be defined as the process of wave ...
Read MoreDifference between Fundamental data types and derived Data Types
In computer programming, a datatype represents the type and nature of data that is to be used by the user. It is the data type that tells the compiler or interpreter how to deal with the data and provide corresponding storing location in computer memory. According to the nature of data, the data types can be of two types namely Fundamental Datatype and Derived Datatype. Both these datatypes are extensively used in computer programming. They are equally important when we require to implement the business logic over the data. Read this tutorial to find out more about Fundamental and Derived ...
Read MoreDifference between DOS and Windows
Both DOS and Windows are types of operating systems. DOS is a single-tasking, single-user and CLI-based OS; whereas Windows is a multitasking, multiuser and GUI-based OS. Read this tutorial to find out more about DOS and Windows and how these two operating systems are different from each other. What is DOS? DOS (Disk Operating System) is a character-based operating system that was developed in the 1980s for IBM-compatible computers. DOS is one of the oldest and widely used computer operating systems. It is a set of computer programs. DOS can perform major functions like file management, allocation of system resources, ...
Read MoreDifference between Data Warehouse and Operational Database
A data warehouse is a repository for structured, filtered data that has already been processed for a specific purpose. It collects the data from multiple sources and transforms the data using ETL process, then loads it to the Data Warehouse for business purpose. An operational database, on the other hand, is a database where the data changes frequently. They are mainly designed for high volume of data transaction. They are the source database for the data warehouse. Operational databases are used for recording online transactions and maintaining integrity in multi-access environments. Read this article to learn more about data warehouses ...
Read MoreDifference between Data Scientist, Data Engineer, Data Analyst
Data scientists, data engineers, and data analysts are all professionals who work with data in some way. However, they have different roles and responsibilities. Read this article to find out more the job profiles of data scientists, data engineers, and data analysts and how you can distinguish among them. Who is a Data Scientist? A Data Scientist is one who analyses and interprets complex data in digital form. Data scientists are responsible for extracting insights and knowledge from data. They use a variety of techniques, including machine learning, to analyze data and communicate their findings to stakeholders. There are several ...
Read MoreDifference Between CAD and CAM
CAD and CAM are the advanced computer-based technologies used in product designing and manufacturing processes. The most basic difference between the two is that CAD (Computer Aided Design) is used for designing of products using some designing software, whereas CAM (Computer Aided Manufacturing) is a software used to control the machines (like CNC machine) involved in industrial processes. Read this article to find out more about CAD and CAM and how they are different from each other. What is CAD? CAD stands for Computer Aided Design. CAD is basically the implementation of digital computers in engineering designing processes. A CAD ...
Read MoreDifference between Arc Welding and Gas Welding
Welding is a process of melting and joining different types of materials together. There are several types of welding processes available that are used based on the types of materials being joined or melted. Two most extensively used types of welding are arc welding and gas welding. The fundamental difference between arc welding and gas welding is that arc welding uses electric current to produce heat for joining of metals, while the gas welding uses flammable gases to produce heat for welding process. Read this article to learn more about Arc Welding and Gas Welding and how they are different ...
Read MoreDifference between Electric Field and Magnetic Field
There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...
Read MoreDifference between Spam and Phishing Mail
Spams and phishing mails are related to social engineering wherein a cyberattacker tries to manipulate a person to reveal the personal information such as password, account details, and many other security credentials. Therefore, we should be very careful while sharing our personal information through digital platforms. But, both spams and phishing mails are quite different from each other in the way they operate and manipulate their victims. The basic difference between the two is that a spam mail is a kind of advertisement tool but it is untargeted, while a phishing mail is a type of targeted social engineering attack. ...
