Importance of Electric Device Knowledge in Computer Science Education

  1. 1. • Syed Ahmed Zaki (131-15-2169) • Md. Sazzad Hossain (131-15-2368) • Md. Nazirul Mobin (131-15-2511) • Md. Rabiul Karim (131-15-2509)
  2. 2. Electronic device is a device that accomplishes its purpose electronically. Mainly electronic devices are those small elements on the the electronical systems which uses to make easy current flow through the whole system. As a whole electronic devices are diodes, transistors , integrated circuits , vacuum tubes etc. Diodes Integrated Circuits(IC) Transistors
  3. 3. Nowadays all of the modern electronics devices like Laptops,Tablet pcs,Smartphones are made up with semiconductors. That is electronic devices.They use semiconductors because: An insulator substances do not conduct electricity very well. And conductors are substances that conduct electricity readily. But a semiconductor is a man made material that can be made to conduct electricity at some times and not conduct at other times. Semiconductors are used to create discrete electronic circuit elements, like, transistors, and diodes, and to simulate resistances, inductance and capacitance, also integrated circuit chips.
  4. 4. The heart of all modern electronic devices are semiconductors and those semiconductors are two types 1. Pure or Intrinsic semiconductors Example: Silicon, Germanium etc. 2. Impure or extrinsic semiconductors They are also two types: p-type semiconductors n-type semiconductors Both n and p type semiconductors are made with doping on the pure semiconductors. As pure semiconductors conductivity is not up to the mark. We use doping method on pure semiconductors to increase conductivity.
  5. 5. P-type materials formed by when the 4 valence electron base Silicon or Germanium mixed with three valence electron base like Boron, Gallium, Indium etc. And by this acceptor whole is created. And it is known as positive type semiconductors n-type materials formed by when the 4 valence elctron base Silicon or Germanium mixed with five valence electron base like Antimony, Arsenic, Phosphorus etc. And by this donor electron is created. And it is known as negative type semiconductors
  6. 6. • The story starts with a man named William Shockley. He was a brilliant academic from equally brilliant roots. His father was a mining engineer fluent in eight languages, and his mother was a highly successful Stanford graduate. • In the 1940s, Shockley was involved in various war-related research efforts surrounding radar and anti-submarine warfare • Through research Shockley created the world's first transistor in 1947 in Bell Lab. • The transistor soon became one of the single most important inventions of the 20th century and is now a key component in just about every modern electronic devices on the market. • He began developing silicon-based semiconductors through the Shockley Semiconductor Laboratory in 1956, the same year he received a Nobel Prize in Physics.
  7. 7. The importance of those electronic devices is huge in computer science education and we will discuss some of these in here: • These devices are made with silicon are the heart of every personal computer. • Semiconductors allow electricity to be used to perform just about all of the useful functions we see in everyday life. • Simple wrist watches to cell phones and others digital devices are made by semiconductors. • Simple calculators to scientific calculators are made with semiconductor chip. • A large number of these semiconductor switches (called transistors) can be built on tiny pieces of silicon and used perform calculations. Even in supercomputers there has been usage of semiconductors • Not only these, In computer signaling we use LED systems which is also made by diodes. • Digital Signaling system is totally dependent on semiconductor technology. • Each and every digital circuit systems like CPU motherboard,Graphics Card,Wrist watch circuit boards etc. are using semiconductor chipset and microchips • Even in memory card to flash drive are using semiconductor technologies for saving data
  8. 8. • Big data center is using semiconductors systems • Cloud computing is totally based on data center • Techgiants like google,facebook,twitter are making millions of data .To save those information they are using harddrives, on the big computer systems which are totally based on semiconductor technologies.
  9. 9. • There are lots of demand of semiconductors on the electronics industries • There has been created lots of semiconductors companies in this world.Some of those prominent companies are:  Intel - the largest maker of Computer CPUs in the world  Texas Instruments - maker of the most popular electronic  calculators and thousands of other semiconductors  Samsung - prominent Korean manufacturer of memory circuits and other electronics  Toshiba - large Japanese manufacture
  10. 10. • Those silicon based semiconductors are made from silicon(Atomic number 14 on the periodic tables) . Those silicon’s came from sands which is known as silica(Silicon Dioxide Si푂2). The silicon is less temparature sensitive and most abundant materials on earth. • As per semiconductor industry is growing huge and big so that in USA at Northern California state a city named Palo Alto which is named after silicon that is Silicon Valley for the purposes of the importance of the place. • Lots of techgiant like Intel,hp,Yahoo,ebay,Google,Apple started their business from this silicon valley.
  11. 11. Without semiconductors this 20th century is like impossible things. Because now, From simple calculator to wrist watch,tablet pcs, personal computers and each and every digital devices are built with semiconductor technologies. Whole data base systems are now rely on semiconductors directly or indirectly. Even the digital lighting systems to surrounding systems all are following semiconductors technology So that this modern age would be impossible without semiconductors that means without electronic device knowledge in the computer science education the modern era would be impossible.
