CHAPTER 2 - Introduction to Computer Architecture

EMBEDDED SYSTEMS

refers to the use of electronics and software within a product, as opposed to a general-purpose computer, such as a laptop or desktop system.

IOT

refers to the expanding interconnection of smart devices, ranging from appliances to tiny sensors.

IOT

primarily driven by deeply embedded devices

-Information technology (IT)

-Operational technology (OT)

-Personal technology

-Sensor/actuator technology

Embedded Operating Systems

Two General Approaches: Take an existing OS and adapt it for the embedded application—Design and implement an OS intended solely for embedded use

Cloud computing

its services first became available in the early 2000s

2012

Apple's iCloud was launched in ____ and had 20 million users within a week of launch

20

Apple's iCloud was launched in 2012 and had __ million users within a week of launch

Cloud computing

A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources

Cloud networking

refers to the networks and network management functionality that must be in place to enable cloud computing

Cloud Service Provider

maintains computing and data storage resources that are available over the Internet or private networks.

Software as a service

saas

SaaS cloud

provides service to customers in the form of software, specifically application software, running on and accessible in the cloud.

Platform as a service

paas

PaaS cloud

provides service to customers in the form of a platform on which the customer's applications can run.

Infrastructure as a service

iaas

IaaS

provides virtual machines and other abstracted hardware and operating systems, which may be controlled through a service application programming interface (API).
