Storage and memory are terms people often get confused when they talk about computers. Some people even use these terms synonymously. Although both storage and memory are used to store information, they differ significantly. Storage holds the information permanently until the user deletes that information. However, the memory holds the information temporarily until the processor is using that information or until the system is powered off. Storage and memory are two of the major holding … [Read more...]

Flash drive and pen drive are memory modules developed using flash memory. Thus, they have similar capabilities and are fundamentally alike. Indeed, a pen drive is just one more form of a flash drive. But the fact is, a flash drive has uses that extend beyond those of pen drives. The flash drive is a larger flash memory module that is now a day rapidly replacing the hard disk drive. On the other hand, a pen drive is just a portable storage tool that uses a USB port to connect to the system. … [Read more...]

RJ11 and RJ12 connectors are standard registered jacks that people use to wire their telephone lines. Both of them use the same six-slot connector but differ in the wiring pattern and the number of wires they use. In RJ11, only four wires are terminated in the connector, whereas in RJ12, six wires are terminated in the connector. This section will identify all the differences between them. So let’s start with the comparison chart. Content: RJ11 Vs RJ12 Connectors Comparison Chart … [Read more...]

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...]
