Week 1: Cloud Computing Models
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources.
Software as a Service (SaaS)
- The consumer uses an application but does not control the operating system, hardware, or network infrastructure on which it’s running.
- Applications are restricted to business applications or applications that may normally be installed in a business network or personal computer.
- Examples:
- Business applications:
CD-ROM, DVD, and Flash Memory Storage Technologies
CD-ROM
Emergence and Evolution of the CD-ROM
The CD technology was a creation of Philips and Sony. In the middle of the decade, the first computer CD drive units were introduced. These units used the same physical format, the CD, but they could contain not only recorded music but also data and computer programs.
- CD-R: This is a recordable CD; however, there is no possibility to delete and start again to record information.
- CD-RW: This CD can erase and rewrite many times as desired.
The Operation of CD

Industrial Robots
An industrial robot is defined as an automatically reprogrammable, multifunctional material handler with three or more axes. It can be positioned and used to orient material, parts, tools, or special devices to perform work in various stages of industrial production, either in a fixed position or while moving. (IFR, ISO / TR 83,737, 1988)
Degrees of Freedom (DOF)
Each of the independent movements that each joint can make with respect to the previous one.
- 3 DOF – is the minimum (as

Flywheel
The flywheel is the part that stores kinetic energy of the working careers or dies and gives non-motor racing. It is also responsible for regulating the operation of motor rotation.
- Its size depends on the number of cylinders, and the greater the number of cylinders, the lower the irregularity of rotation.
Process control:
- Reduces engine vibrations.
- A certain number of revolutions in the car shake when you release the clutch: incorrect link starter pinion to the crown.
Semiconductor Fundamentals: Intrinsic, N-Type, and P-Type
Semiconductor Fundamentals
A semiconductor is a material element whose electrical conductivity lies between that of an insulator and a conductor.
The best-known semiconductors are silicon (Si) and germanium (Ge). Because the behavior of silicon is more stable than germanium against external factors that can alter its normal response, silicon (Si) is the most commonly used semiconductor element in the manufacture of solid-state electronic components. We will generally refer to silicon, keeping in mind
