Bandwidth Bottlenecks – A Limit of Enterprise Cloud Computing?

Posted on June 28, 2012 by Cornelia Nussbaum, PhD

More and more enterprises are transferring their data into the cloud and excitement about scalability, cost-saving, improved data and customer management. With increasingly improved security management, cloud computing seems to be the ultimate solution of any IT problem.

The limiting factor for data transfer from Local Area Networks (LAN) into the cloud is b bandwidth.

Network bandwidth, or digital bandwidth, is defined as “computer network’s net rate” which is the amount of data transfer, channel capacity or maximum throughput of a logical or physical communication path. It is measured as “bytes per second (bps)” for digital services or Hertz (Hz) for analog devices. Continue reading “Bandwidth Bottlenecks – A Limit of Enterprise Cloud Computing?” »

Supercomputers

Posted on June 28, 2012 by Cornelia Nussbaum, PhD

Supercomputers, also referred to as High Performance Computing (HPC), is technology at the forefront of present processing abilities, particularly as being the fastest type of computing today.
Indeed, supercomputers are millions of times more powerful than regular traditional desktop computers Continue reading “Supercomputers” »

DNA-Based Computation

Posted on June 25, 2012 by Cornelia Nussbaum, PhD

DNA computing uses chemical reactions to solve problems with DNA (deoxyribonucleic acids) strands acting as “bits”.

The pioneer of DNA computing is Leonard Adelman (University of Southern California) who in 1994 proposed that DNA computers (nanocomputers) can solve complex mathematical problems. He proved his concept by using DNA to solve the Hamiltonian path problem (Traveling Salesman Problem). Continue reading “DNA-Based Computation” »

Cyber Security Threats III – Malware

Posted on June 25, 2012 by Cornelia Nussbaum, PhD

Malicious software, or malware, means hostile, intrusive or annoying software, script or code that is designed to alter or damage computer operation, collect private and sensitive information and gain unauthorized access to computer systems.

Microbots – How small can a computer be?

Posted on June 21, 2012 by Cornelia Nussbaum, PhD

Microbots, also called nanobots, are miniaturized, sophisticated machines with power and control on-board that perform specific tasks repetitively with precision.

Microrobots usually are as small as a fraction of a millimeter – up to several millimeters and can be either autonomous or insect-like. Continue reading “Microbots – How small can a computer be?” »

Business as a Service (BaaS) – The New Cloud Management Concept

Posted on June 21, 2012 by Cornelia Nussbaum, PhD

More and more enterprises seek the help of third-parties to host business solutions rather than sourcing hardware and software themselves. The Software as a Service (SaaS) model allows those enterprises to get more efficient to achieve business agility. SaaS is reused across multiple channels, markets and customer segments. Continue reading “Business as a Service (BaaS) – The New Cloud Management Concept” »

Migrating the Cloud

Posted on June 18, 2012 by Cornelia Nussbaum, PhD

Moving a software application to the cloud merely means running it in the web rather than on the traditional data center infrastructure.
The main advantages to migrate data and software operations to the cloud include Continue reading “Migrating the Cloud” »

Cybersecurity Threats II – DoS and DDoS attacks

Posted on June 18, 2012 by Benjamin Nussbaum

Denial of Service (DoS) attack is a network attack that prevents users from accessing a website or service by overloading a web server with “useless” information.
Most of these compromised systems attack a single target by flooding it with a huge number of incoming messages in high frequency. Since a server can only process a certain amount of requests at once the attack overwhelms the processing capacity and forces the system to shut down, thus, rendering the website as inaccessible and denying the service to the real users. Continue reading “Cybersecurity Threats II – DoS and DDoS attacks” »

Nanotechnology in Manufacturing

Posted on June 14, 2012 by Cornelia Nussbaum, PhD

Manufacturing at the nanoscale is also called “molecular manufacturing” or “nanomanufacturing”. It involves scaled-up, reliable, clean and cost-effective manufacturing by moving atoms and molecules into desired nano-sized materials, structures, devices and/or systems to build immensely small electronic circuits and mechanical devices.
The development and use of such atomically precise manufacturing has the capability to radically change the manufacturing capabilities of the whole world. Continue reading “Nanotechnology in Manufacturing” »
