What Is RISC? RISC (Reduced Instruction Set Computer) is an architecture designed for simplicity and efficiency. Key characteristics include: What Is CISC? CISC (Complex Instruction Set Computer) features a more complex instruction set aimed at ease of programming. Key characteristics include: Key Differences Between RISC and CISC Instruction Set Design Register Usage Memory Access…
Introduction: MBR vs GPT – What’s the Difference? When setting up a storage drive, the choice between MBR vs GPT plays a critical role in performance and compatibility. MBR (Master Boot Record) is an older standard suitable for smaller drives and older systems, while GPT (GUID Partition Table) supports larger drives and offers advanced features for modern systems. What Is MBR? The Master Boot Record (MBR) is a traditional disk partitioning scheme widely used in early computer systems. It resides in the first sector (512 bytes) of a hard disk and contains a partition table and a small program (boot…
Introduction: WiFi vs Internet – What’s the Difference? When it comes to connectivity, WiFi vs Internet highlights two essential but distinct technologies. WiFi provides a local wireless network for device communication, while the Internet connects you to the global web. Understanding their differences can help you optimize your network and troubleshoot common issues. What Is WiFi? WiFi, based on the IEEE 802.11 family of standards, is a wireless networking technology commonly used for local area networking of electronic devices and Internet access. It enables devices like smartphones, tablets, laptops, and desktops to connect to a wireless access point or hotspot,…
What Is QSFP28? QSFP28 (Quad Small Form-factor Pluggable 28) is a high-density, hot-pluggable fiber optic transceiver standard designed for modern data communication networks. It is an evolution of the QSFP+ standard, offering higher data rates and port densities. How QSFP28 Works QSFP28 (Quad Small Form-factor Pluggable) transceivers operate on the principle of parallel optics, utilizing four independent full-duplex channels, each capable of transmitting data at a rate of 25 Gbps.
