Timeline of Computer History
Computer History Museum, 2016. Timeline of Computer History: Memory and Storage. [Online] Available at: https://www.computerhistory.org/timeline/memory-storage/ [Accessed 10 September 2016].
This resource is a website of the computer history museum which discusses the timeline of computers. The author has discussed Williams Tube and Magnetic Core Memory along with other mass storages technologies that existed prior to 1980. According to this site, Williams-Kilburn Tube which was tested in 1947 was the first completely electronic memory having high speed which made use of a cathode ray tube for the storage of bits in the form of dots on the surface of the screen. There was constant refreshment of information as every dot would last for only a fraction of a second prior to fading away. The changes in electrical charge were determined by a metal pickup plate. On the other hand, Magnetic Core Memory was the first system of high speed RAM that was considered to be reliable and till the 1970s it had wide usage as the computers’ main memory technology.
History of Data Storage Technology
This resource is a blog by the Zettta staff and it discusses the data storage technology’s history. As per this website, Delay Line Memory was used from 1949 onwards and it consisted of imparting a pattern of information into a “delay path”. The information recirculation was allowed by a close loop that was formed if the delay path connected to the start via time and amplifying circuits. The function of this storage is similar to the input of a telephone number from the directory that is repeating till it is dialled by the person. Another mass storage technology that this website describes is the DRAM cells. The technology of memory cells or the “Dynamic Random Access Memory” consisted of a single transistor. The bits of information were stored by the cells in a circuit in the form of electrical charge. The overall density of memory was increased by DRAM cells.

Griffin, D., 2011. How does the Global Positioning System work ? [Online] Available at: https://www.pocketgpsworld.com/howgpsworks.php [Accessed 10 September 2016].
This resource is an article from a weekly newsletter pocketgpsworld. In this the author Griffin speaks about the working of the Global Positioning System navigation system, an embedded operating system. Griffin explains the way in which the signals are transmitted by the GPS satellites to a GPS receiver and that the operations of GPS are dependent on time reference that has to be highly accurate and this is given by the atomic clocks that are present on board the satellites. The transmission of data by each satellite is an indication of its location as well as the current time. I found this information to be useful as the author explains in detail not only the satellite network but also the way in which the GPS is used for determining the position. The way in which the operations are synchronised by all GPS satellites is also well explained by the author.
Operating Systems in Microwave Ovens
Gish, W., 2016. Operating Systems in Microwave Ovens. [Online] Available at: https://www.ehow.com/info_12177413_operating-systems-microwave-ovens.html [Accessed 10 September 2016].
This resource taken from the e-How website talks about the operating system in microwave systems. According to the author Gish, there are two systems that are present in all the microwave ovens – the “electrical operating system” due to which heating and cooking of food occurs and the “computer operating system” which helps in transferring directions from the controls to the first system. The author also explains the parts of the two systems in order to understand its working. According to me this article is very useful in understanding the differences that are there between the embedded systems and the operating systems and the way the embedded systems work especially in the case of microwave ovens wherein the embedded systems perform the role of translating the simple commands. The article explains that in microwave ovens the operating system works as a command device and hence microwave oven contains a simple programming.
