The Central Processing Unit (CPU) is the command center in a computer or mobile computing device, hosted on the device's microprocessor. The CPU takes in commands and executes them. In multi-core CPUs, more commands can be executed at once.

Single-core CPUs have traditionally powered smart-phone and tablet devices, but dual-core processors and even tri- and quad-core CPU-powered devices are being introduced in 2011. (See CES 2011: Top 10 Cool Things at CES, CES 2011: Acer Demos Dual-Core Tablets, CES 2011: OS Watch Goes Gadgets, Moto, AT&T Intro Atrix 4G and Samsung & LG Dual It Up.)

Companies that make CPUs include Intel Corp. (Nasdaq: INTC), Texas Instruments Inc. (NYSE: TXN), Advanced Micro Devices Inc. (NYSE: AMD), Marvell Technology Group Ltd. (Nasdaq: MRVL), Qualcomm Inc. (Nasdaq: QCOM), Samsung Corp. , Freescale Semiconductor Inc. and Nvidia Corp. (Nasdaq: NVDA).

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
