The document summarizes the history and major developments of Intel and AMD, the two largest microprocessor manufacturers. It describes how Intel was founded in 1968 and became the dominant player with innovations like the Pentium processor and Intel Inside marketing campaign. AMD was founded a year later and grew by partnering with other companies, eventually producing its own x86-compatible processors. Both companies introduced numerous processor families over the decades as clock speeds and core counts increased. Intel remains the market leader while AMD focuses on graphics and accelerating CPU functions.Intro ch 05_b

A System on Chip (SoC) is a microchip that integrates all components found in a computer onto a single chip, making it function as a whole computer. It contains a microcontroller, microprocessor or digital signal processor core, memory blocks like RAM and ROM, timing sources, peripherals, external interfaces, analog interfaces, and power management circuits. While a microcontroller typically has under 100kB of RAM and is a single-chip system, an SoC is more powerful and requires external memory to run software like desktop operating systems. It allows smartphones and tablets to function as smaller computers by integrating all necessary components onto one chip.Assic 28th Lecture

Namun, penjajahan Portugis, Belanda, dan British seterusnya telah memberikan kesan terhadap struktur masyarakat dan politik yang wujud di tanah melayu, membentuk identiti pelbagai budaya yang kita lihat hari ini.edu pengurusan bilik darjah sekolah rendah
