Both flash memory and EEPROM are non-volatile memories, which means they can hold onto data even when the power is turned off. However, the two forms of memory do differ in several significant ways. New data can be written immediately after flash memory's contents have been erased. On the other hand, in order to write fresh data to an EEPROM, it must first be wiped. Flash memory can normally be overwritten about 100, 000 times, before it begins to degrade. Only a few thousand times can an EEPROM typically be written before it needs to be changed. Flash memory ... Read More

Before discussing the above categories, let's define computer memory. The data is kept as 0s and 1s so the user can save and retrieve it. Memory is like a person's brain. Computer memory allows speedy data access. The CPU may talk to the application faster. Without computer memory, the user couldn't save anything.Computer memory stores data either temporarily or permanently, based on which it is classified as either primary (internal memory) or secondary (external memory).There are two types of memory −External Memory − Most of the time, external memory means storing files on an external hard drive or on the ...

We can define an address mode as the way in which the memory address of an operand is specified in a computer instruction. Address modes specify how the location of an operand in memory is represented in an instruction. Operations are performed with the help of some data and the data is stored in a computer memory or registers. On the basis of that, there are two types of addressing modes namely, memory address mode and register address mode. The most basic difference between the two is that in the memory address mode, the address of the operand is present ... Read More

In the field of cognitive science and artificial intelligence, the knowledge of brain and computer is very useful. In artificial intelligence, the human brain is analyzed and used to model different kinds of artificial neural networks to develop a computerized expert system. The basic difference between the brain and computer is that the brain is a natural organ of human body that can make decision on its own, while the computer is a manmade machine that requires sufficient data and instructions to make a decision. In this article, we will discuss all the major differences between brain and computer ... Read More

SIMM and DIMM are types of memory modules which are designed to eliminate the use of Dual Inline Package (DIP) chips because the installation of DIP chips is difficult. The basic difference between the two is that SIMM has only one side that is usable at a time because it has only one set of connector, whereas DIMM has different usable pins at each side. Read this article to learn more about SIMM and DIMM and how they are different from each other. What is SIMM? SIMM stands for Single In-Line Memory Module. SIMM is a type of memory module ...

SIMD and MIMD are types of computer architectures that are used to improve the performance of certain types of computational tasks. The basis of this classification is the number of data and instruction streams. SIMD, short for Single Instruction Multiple Data, computer architecture can execute a single instruction on multiple data streams. On the other hand, the MIMD (Multiple Instruction Multiple Data) computer architectures can execute several instructions on multiple data streams. Read this article to find out more about SIMD and MIMD architectures and how they are different from each other. What is SIMD? SIMD is a form of ... Read More

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 ...

There are two types of addressing modes, namely, direct addressing mode and indirect addressing mode. In direct addressing mode, the actual address of the data is mentioned in the instructions itself. On the other hand, indirect addressing mode contains the effective address of the memory location where the actual address of the data resides. Read this article to find out more about direct and indirect addressing modes and how they are different from each other. Let's start with a basic introduction of these two types of addressing modes. What is Direct Addressing Mode? The Direct addressing mode is one that ... Read More

What is USB?A Universal Serial Bus (USB) is a communication interface that allows devices to communicate with a host controller such as a computer system. It links peripheral devices including digital cameras, mice, keyboards, scanners, printers, media players, flash drives, and external hard drives to a computer.A USB may be used for a multitude of things, including providing electrical power, which is why the USB has replaced an array of interfaces like the parallel and serial ports.USB ports are used to connect peripheral devices to computers in a variety of ways.USB 1.xIt is an external bus standard that supports up ...

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 ...
