Understanding and Modifying MAC Addresses in Network Devices
What Is a MAC Address?
A MAC (Media Access Control) address serves as a unique hardware identifier assigned to a network interface controller (NIC). It operates at the data link layer of the OSI model and is essential for local network communication. Unlike IP addresses, which can change dynamically, MAC addresess are typically hardcoded into t ...

Implementing I2C Communication with AT24C02 EEPROM on 8051 Microcontrollers
Overview of Memory Types
Memory is broadly categorized into RAM (Random Access Memory) and ROM (Read-Only Memory). RAM offers fast access but loses data when power is removed. ROM is slower but retains data without power.
RAM Variants
SRAM (Static RAM): Utilizes flip-flops for data storage, providing very high speed. Commonly used in CPU cache ...

FPGA Implementation of EEPROM Communication Using the I2C Protocol
The Inter-Integrated Circuit (I2C) interface operates over a bidirectional two-wire connection. The serial data line is designated as SDA, while the serial clock line is labeled SCL. To acommodate multiple devices sharing the same bus, these lines typically utilize an open-drain configuration, requiring external pull-up resistors to maintain pr ...
