Cache memory and register both are the memory units of the computer. But they are not the same in terms of speed, size, access time, etc. Cache memory is an individual memory unit that stores the data that has been used recently by the processor. On the other hand, the register is a high-speed storage element that holds the data that the CPU is currently processing. Whenever the processor fetches any instruction or the associated data from the main memory into the processor chip (registers), … [Read more...]

Cache and main memory both are inboard computer memory. The cache holds the frequently used data. On the other hand, the main memory (RAM) holds the data that is currently in execution. The cache is much faster and more expensive than the main memory. However, both of these computer memories are directly accessible by the processor. Now before going ahead let us discuss what is computer memory. What is a Computer Memory? Memory is a hardware device used to store programs or data. Memory … [Read more...]

The CPU and ALU are the parts of the computer, without which a computer would never work well. Here, the main difference between CPU and ALU is that the CPU handle almost all the task that goes in the system while ALU handles the only arithmetic operation of the computer. CPU is intended to use the information in the program memory (instruction) to control the operation of the device. These instructions operate on the data memory and to operate on the data memory the logical arithmetic unit is … [Read more...]

We know that with computers we need to do the manual insertion of the inputs in the early developing stages of the computers. So, the OMR and OCR are the technologies designed to directly capture and enter the data into the system without needing any human intervention. These methods of inserting the data directly to the system is very useful as it facilitates bulk data entry with accuracy. The major differences between the OMR and OCR is that OMR is a data collection technology. In contrast, … [Read more...]

The FPGA and CPLD devices were developed with the intent of achieving the circuit density and speed like ASIC (Application Specific Integrated Circuit) but with a smaller turn around time for the programmable devices. The main difference between the FPGA and CPLD is that FPGA provides extensive logic resources as compared to the CPLD, which is simple and contain less number of interconnections. For segregating the FPGA and CPLD, mainly two things are considered. First, is their architecture … [Read more...]

For displaying the content over the various display devices, a various organization has developed the display standards. VGA and SVGA fall in the category of these standards used for channelling the video data to a suitable visual output. VGA (Video Graphics Array) supports smaller resolution videos and images while SVGA is a standard provide large resolution for the displaying the content. Content: VGA and SVGA Comparison Chart Definition Key Differences … [Read more...]

The MPLS and VPN are the acronyms majorly used in networking, where both intend to perform different functions. The significant difference between MPLS and VPN is that the MPLS is used for generating a predetermined route with the help of labels that behaves like circuit-switched connection, but it can deliver layer 3 IP packets also. On the other hand, the VPN establishes a secure encrypted connection with the help of an additional server for delivering the information. Furthermore, the MPLS … [Read more...]

Hue and saturation are properties of the colour. The main difference between them is that the hue is the purest form of the colour whereas saturation is the degree of brightness and dullness of a hue. Generally, the colour are measured in the range of 0 to 360 degrees where red lies in 0, green at 120 and blue at 240. Now, most of the colour wheels work in degrees where angles in the colour wheel are measured, but in the case of computers, the concept is quite modified where everything exists … [Read more...]

The USART and UART can be fundamentally distinguished by the fact that UART transmits and receives asynchronous serial data. In contrast, the USART is intended to transmit-receive the synchronous serial data. Furthermore, the USART is a combination of both USRT and UART, which means it can perform both synchronous and asynchronous transfer of the data. These peripherals - USART and UART are mainly used as the auxiliary device with the microcontrollers for translating the ingoing and outgoing … [Read more...]

USB 2.0 and USB 3.0 are the different specifications of the USB where the USB 2.0 specification was released before the USB 3.0. The latter version USB 3.0 has many advantages over USB 2.0 as it is the successor of the version of 2.0. The most crucial difference lies within the speed of the data transfer, where the USB 2.0 transfers at the rate of the 480 Mbps. On the other hand, the USB 3.0 support the speed up to 5 Gbps. There are several more differences between the USB 2.0 and USB 3.0 … [Read more...]
