Difference Between NC and CNC
In this post, we will understand the difference between NC and CNC −NC (Numerical Control)It stands for Numerical Control.The input mechanism is punched tapes and punched cards.The modification in the machine programs can be done by changing the information on punched cards.The operational parameters can’t be changed.There is no memory to store instructions in them.It is less expensive.It requires very less maintenance.It is moderately accurate.The operators using this need to be highly skilled.It is not very flexible.It consumes more time.CNC (Computer Numerical Control)It stands for Computer Numerical Control.The input mechanism is that the program is fed data with the help ...
Read MoreDifference Between RGB and CMYK
In this post, we will understand the difference between RGB and CMYK colour schemes −RGB Colour SchemeIt is used with digital works.The primary colours in this scheme are ‘Red’, ‘Green’, and ‘Blue’.It is an additive Type Mixing scheme.The colours of this scheme’s images are more vibrant.It has a wide range of colours in comparison to CMYKThe file formats to work with this colour scheme are JPEG, PNG, and GIF.CMYK Colour SchemeIt is used with print works.The primary colours in this scheme are ‘Cyan’, ‘Magenta’, ‘Yellow’, and ‘Black’.It is a subtractive Type Mixing scheme.The colours of this scheme’s images are less ...
Read MoreDifference Between USART and UART
In this post, we will understand the difference between USART and UART modes −USART (Universal Synchronous/Asynchronous Receiver/Transmitter)The half-duplex mode is used.The speed of USART is more in comparison to UART.It uses data signals as well as clock to work.The data is transmitted in the format of blocks.It can work similar to UART.It is more complex in comparison to UART.The receiver doesn’t require to know the baud-pace of the transmitter.This is because it gets information by the master and the clock signal.The data is transmitted at a definite (specific) rate.UART (Universal Asynchronous Receiver/Transmitter)It uses full-duplex mode.Its speed is less in comparison ...
Read MoreDifference Between WordPress.com and WordPress.org
In this post, we will understand the difference between wordpress.com and wordpress.org −Wordpress.orgIt is also known as the real WordPress.It is open source, and can be used by anyone.A domain name and a web hosting service is required to use this.It is also referred to as self-hosted WordPress.User has full control of the website.WordPress plugins that are free, or paid can be added to the website.The website and all of its data is owned by the user.Google analytics can be used to perform customized analytics.Advertisements can be run and revenue can be generated.User has to keep several backups of the ...
Read MoreDifference Between Website and Blog
In this post, we will understand the difference between a website and a blog −WebsiteIt is a collection of webpages and multimedia content.This is made available under one domain on the World Wide Web.The websites are usually hosted using a web hosting service.This allows the web pages and the content of the website to be accessed by people all over the world.It can be an internal site that could be accessed through a secure local area network.The fundamental unit of a website is content.It doesn’t have any kind of order.Commenting on a website is not possible all the time.There are ...
Read MoreDifference Between Hypertext and Hypermedia
In this post, we will understand the difference between hypertext and hypermedia −HypertextIt refers to the system of managing the information related to the plain text.It involves only text.It becomes a part of the link.It is the part of hypermedia.It allows the user to traverse through text in a non-linear fashion.It allows users to move from one document to another in a single click.The user can click on the hypertext or the ‘goto’ links.It helps the user move to the next document.It also helps the user move from one page of a document to the other page.It doesn’t provide a ...
Read MoreDifference Between Internal and External fragmentation
In this post, we will understand the difference between internal and external fragmentation −Internal FragmentationThe difference between the memory allocated and the space required is known as internal fragmentation.In this fragmentation, fixed-sized memory blocks are used to process data.This process occurs when a method or process is larger than the required memory.The method used in internal fragmentation is ‘best-fit’ block.It occurs when the memory is divided into fixed sized partitions.External FragmentationThe unused spaces that is formed between fragments of non-contiguous memory, which are too small to help with a new process, is known as external fragmentation.It uses variable-sized memory blocks ...
Read MoreDifference Between Linker and Loader
In this post, we will understand the difference between a linker and a loader −LinkerThe main function of the linker is to generate executable files.The linker takes the input as the object code which would be generated by a compiler/assembler.The process of linking can be understood as a method to combine different snippets of code in order to obtain executable code.There are two types of linkers available: Linkage Editor and Dynamic Linker.Linker also helps combine all the object modules.Linker is responsible to arrange the objects in the program’s address space.LoaderThe main function of a loader is to load executable files ...
Read MoreDifference Between Stack and Heap
In this post, we will understand the difference between Stack and HeapStackIt is a linear data structure.Memory is allocated in a contiguous (continuous) block.The memory for a stack is allocated and deallocated automatically using the instructions of the compiler.It costs less to build and maintain a stack.It is easy to implement.It is fixed in size; hence it is not flexible.Its only disadvantage is the shortage of memory, since it is fixed in size.If all the blocks are not occupied, memory gets wasted too.It takes less time to access the elements of a stack.It has an excellent locality of reference.HeapIt is ...
Read MoreDifference Between Trigger and Procedure
In this post, we will understand the difference between trigger and a procedure.TriggersIt is implicitly invoked when an event such as INSERT, DELETE, and UPDATE occurs in a table of a database.Nesting of triggers can be achieved using a table.A trigger can’t be called or defined inside another trigger.Transactional statements such as ‘COMMIT’, ‘ROLLBACK’, ‘SAVEPOINT’ can’t be used in triggers.They are used to maintain referential integrity.This is done by keeping a record of the activities performed on a table.No values are returned in a trigger.No value can be passed as a parameter to a trigger.Syntax to define a trigger:CREATE TRIGGER ...
