Difference between DDR3 and DDR5
DDR stands for Double Data Rate. It is a version of RAM (Random Access Memory). The DDR RAM is capable of transferring data on both edges, i.e. falling edge and rising edge of the clock pulse. Thus, it doubles the data transfer rate, hence it named so. The DDR RAM also comes in several versions (or generations), such as DDR, DDR2, DDR3, DDR4, and DDR5. Each version/generation of the DDR RAM offers enhanced performance in terms of speed, storage capacity, energy efficiency, etc. In this article, we will discuss the two generations, i.e. DDR3 and DDR5 of the DDR RAM, ...
Read MoreDifference between AVR and ARM
A microcontroller is a small processing device which is primarily designed to perform specific functions within a large system. For example, a microcontroller is used in an air conditioner to automatically control and adjust the temperature of a room. The main parts that a microcontroller has are: central processing unit (CPU), memory unit, and I/O interfaces. All these components of the microcontroller are formed on a single chip. A microcontroller can be programmed using various programming languages like C language, assembly language, etc. to perform a specific function. Microcontrollers are widely used in a variety of electronic devices, such as ...

Read MoreDifference Between MLC and SLC
MLC and SLC is a form of NAND flash memory that are used in SSDs, USB drivers, and memory cards. MLC (Multi-Level Cell) flash memory is a form of NAND flash memory that can store several bits of data per memory cell. SLC stands for single-level cell, and each cell holds only one bit of information. Read this article to find out more about MLC and SLC and how they are different from each other. What is MLC? MLC stands for multi-level cell, and it stores two or more bits of information per cell. This means that each memory cell ...
Read MoreDifference Between DMA and PIO
DMA (Direct Memory Access) and PIO (Programmed Input/Output) are two techniques of data transport between a peripheral device and a computer system. DMA (Direct Memory Access) is a data transfer method in which a peripheral device can directly access system memory without involving the CPU. PIO is a technique that allows the CPU to handle data transfers between a peripheral device and system memory. Read this article to find out more about DMA and PIO and how they are different from each other. What is DMA? DMA is a data transfer method in which a peripheral device can directly access ...
Read MoreDifference between EEPROM and Flash
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 MoreWhat is Remote Code Execution (RCE) ?
Remote code execution(RCE) is an arbitrary code running on a remote system using security vulnerability and connecting it to a private or public network. Physical access is not required. The RCE can have severe consequences of Malware, loss of data, Service disruption, and ransomware deployment. The RCE vulnerability is exploited by the attacker without any access to the victim's system. When we download malicious software or application then it gives rise to the use of RCE by cyber attackers. The OWASP has recognized Remote procedure code as a vulnerability for cyber attacks. Overview Definition Remote Code Execution is a remote ...
Read MoreTypes Of Memory On A Cisco Device
Cisco provides products and services to help in building computer networks, including switches, routers, and software at individual and business scales. All the networking hardware, operating systems, and routers use different types of memory and it is determined by what functions the memory serves in the system. For example, a router ensures a secure path for the successful delivery of data transmission. Router uses a routing table where static and dynamic addresses are allocated which helps in successful transmission. These addresses are stored in memory. For easy and effective handling of data and information, memory is categorized into different types. ...
Read MoreDifference between Hard drives and Flash drives
Hard drives and flash drives are the two major types of storage devices used in computer systems for permanent data storage. The most basic difference between these two storage devices is that a hard drive is an electromechanical storage device having some movable parts, whereas a flash drive is an electronic storage device made of integrated circuits. Read this article to learn more about hard drives and flash drives and how they are different from each other. What is a Hard Drive? A hard drive is an electromechanical storage device used in computer to store data and information permanently. ...
Read MoreCopy on Write in Operating System
Copy-On-Write (COW) memory management is a memory optimization technique employed by operating systems to reduce overheads when creating new processes. It facilitates multiple processes to share the same memory pages until one process modifies them. Upon modification, the operating system creates a duplicate copy of the original page, which is exclusively granted to the modifying process, while the other processes continue to share the original page. This technique is especially advantageous while creating new processes, as it enables the new process to share the memory pages of the parent process until it requires modifying them. By significantly saving memory and ...
