Introduction to information and computer science

Introduction to Information and Computer Science

The Future of Computing

Lecture b

This material (Comp4_Unit10b) was developed by Oregon Health and Science University, funded by the Department of Health and Human Services, Office of the National Coordinator for Health Information Technology under Award Number IU24OC000015.


The future of computing introduction lecture b

The Future of ComputingIntroduction – Lecture b

  • Describe the latest advances in technology (Lecture a, b)

  • Discuss the implications of advances in technology for healthcare systems, including potential risks (Lecture a, b)

Introduction to Information and Computer Science The Future of Computing Lecture b


Cloud computing

Cloud Computing

Introduction to Information and Computer Science The Future of Computing Lecture b

"Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.“ (NIST, 2011)


Distributed computing

Distributed Computing

Introduction to Information and Computer Science The Future of Computing Lecture b

  • Sharing the processing workload between connected computer systems

  • [email protected]

    • examines radio telescope data for signs of intelligence using computers connected over the Internet

    • volunteer computing resources


Cloud computing characteristics

Cloud Computing Characteristics

Deployment models

Deployment Models

Introduction to Information and Computer Science The Future of Computing Lecture b

Private cloud

Community cloud

Public cloud

Hybrid cloud


Virtualization

Virtualization

Introduction to Information and Computer Science The Future of Computing Lecture b

Multiple virtual computer systems running on a single physical system

Component of cloud computing

Not a new idea; IBM’s Virtual Machine Facility/370 released in 1972

Each user appeared to have a dedicated system


Hypervisor

Hypervisor

Introduction to Information and Computer Science The Future of Computing Lecture b

Virtual systems do not have to be the same operating system or instruction set as the physical hardware

Virtual systems are managed on the physical system by a hypervisor

The hypervisor emulates the instruction set of the virtual hardware

Available through open-source software and commercial vendors

90% of all e-mail is estimated to be spam

Rejected by ISPs or mail servers


Instant messaging

Instant Messaging

Introduction to Information and Computer Science The Future of Computing Lecture b

Initially used to communicate to computer mainframe operators

Could communicate between users on same system

Can now be used to send text between users over global Internet

Computers have become portable

Laptops since the 1990s

Netbooks since the early 2000s

Personal Digital Assistants (PDAs)

Computers are everywhere

Cars

TVs

Home appliances


Personal area networks pans

Personal Area Networks (PANs)

Introduction to Information and Computer Science The Future of Computing Lecture b

Bluetooth

Wireless connection

1 to 100 meter range connection radius

Used for mice, keyboards, headsets, etc.


Implications for healthcare
