Compare solid-state storage to magnetic and optical storage media

  • A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads. SSDs, in contrast, use microchips which retain data in non-volatile memory chips, and contain no moving parts.
  • Magnetic storage and magnetic recording are terms from engineering referring to the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory.
  • Optical storage is a term from engineering referring to the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning disc.

Teleconferencing technology

  • Teleconferencing technology has provided businesses with an entirely new way of communicating over long distances.
  • In fact, it helps business save money on travel expenses and has also helped business owners increase the productivity of their business by providing them with the ability to communicate via telecommunication methods.
  • Teleconferencing technology gives businesses the ability to have meetings over long distances, conduct business briefings, employee training sessions, workshops, seminars, lectures and more between individuals who might not otherwise be able to easily get together.

Solid-state storage

  • Solid-state storage is a nonvolatile, removable storage medium that employs integrated circuits (ICs) rather than magnetic or optical media. It is the equivalent of large-capacity, nonvolatile memory. 
  •  Solid-state storage media lags behind electromechanical drives in terms of storage capacity. As of this writing, flash memory USB devices can store up to approximately 1 gigabyte (GB), whereas hard drives commonly hold 100 GB or more.

List of components and features that the student should consider when purchasing a computer.

  •  Verify first that the computer has no physical damage, inside and outside the case.So the computer will be performed.
  • Make sure a computer comes with any Cd's has no damage, and for the operating system that will be performed or to installed.
  • See the details of computer that could manufacturer of the company.

Computer’s power management settings

  • Power management of personal computers (PCs) and monitors has the potential to save significant amounts of electricity as well as deliver other economic and environmental benefits
  • One of the leading power-management advocacy organizations in the United States, recommends the following power-management settings:   Monitor/display sleep: Turn off after 15 minutes or less. Turn off hard drives/hard disk sleep: 15 minutes or less.System standby/sleep: After 30 minutes or less. 
  • You can save energy, save money, and help the environment by activating power management features on your computer. Benefits include. Cutting the electricity used by your PCs roughly in half, saving $25–75 per PC annually. Estimate your savings using our online calculator. Enhancing data security by reducing the chance that valuable personal information is displayed on an unattended PC.Saving time by eliminating the daily wait for computers to boot up.Helping the environment. Saving energy reduces air pollution associated with the burning of fossil fuels, and ultimately lowers the risk of global warming.

Dr. M.E." Ted " Hoff Engineer and Inventor of Microprocessor

  • He designed the computer-on-a-chip microprocessor (1968), which came on the market as the Intel 4004 (1971), starting the microcomputer industry.
  • November of 1971 Intel publicly introduced the world's first single chip microprocessor called the Intel 4004.  It was invented by Intel engineers Ted Hoff, Federico Faggin, and Stan Mazor.  The Intel 4004 was smaller than a thumbnail, packed 2,300 transistors, executed 60,000 operations a second, and sold for $200 at the time.
