So it is fastest processor ever designed, what about its power consumption? Does 1000 cores dissipate more energy? Developer UC Davis claims that this processor is not only fast but is power efficient too it can run on single AA size battery (0.7W) and use energy so efficiently that each core is independently clock and shut down when they are not being used. The cores also transfer data directly among each other, rather than leaning on a shared cache of memory which save use of extra power.

Should we find a better way to store and secure our data? The answer is YES, Let’s see how? DNA molecules will store data. DNA molecules can store data more compactly than current data storing techniques. Developers have developed a complete system to encode, write and retrieve data from DNA molecules but the system is still in developing process, Researches from university of Washington and Microsoft are making lots of improvements in this system to secure data in efficient way.
Optical device can store 10GB/mm^3. Recent research reported feasibility of optical discs capable of storing 1 PB data, yielding a density of about 100 GB/mm3. But still storing data in Zetta Bytes requires millions of units, its durability is also critical and requires maintenance to replace faulty units. DNA molecule can store digital data for long term and is extremely dense, estimated half life of DNA molecule is about 500 years. The write process (synthesis) for DNA storage maps digital data into DNA nucleotide sequences. Reading the data involves sequences the DNA nucleotide and decoding it back to retrieve original data. DNA storage technology is growing faster, in 1999 DNA-based storage was encoding and recovering a 23 character message while in 2013 developer successfully stored and retrieved 739kb data. Now the researches successfully saved and retrieved four images without losing a single bit of data. The 555 timer is the most popular integrated chip. It is used as oscillator in electronics circuits, the 555 timer is capable of being used in astable and mono stable circuits. Its output always alternates between VCC and zero volts. 555 timer is usually used in counter IC's and where we need clock pulse, so it is important to know how to properly wire 555 timer circuit and how to set required duty cycle of output clock.
You can set duty cycle of output clock by changing the values of R1, R2 and C1 as follows 1- Increasing R1 will increase High Time and increase Low time. 2- Increasing R2 will increase High Time but will not change low time 3- Changing C1 will change cycle time and reduce the frequency of output generated clock. Note: If your timer is not working check pin number 4 (Reset Pin), as you can see in diagram pin 4 is active low so make sure it is connected to positive terminal. Every electronics device need specific voltage to perform operation, In some circuitry voltage fluctuation is fatal (e.g in microcontrollers) so we need constant output voltages, for this purpose we use different voltage regulators. There are so many different ways to regulate the voltage, one of them is using "Voltage Regulator IC's". These IC's come in series of 78xx. e.g Use IC 7805 to 5 volts output, 7806 to 6 volts, 7809 to 9V and similarly 7812 regulates 12V output DC voltages.
These IC's have three terminals input, ground and output. 1- Input 2- Ground 3- Output The maximum input voltages for 7805 is about 35 volts. IC would damage if input voltage exceeds the limit. Higher the input voltages, the more will be heat liberated. Note: If your IC is getting hot use heat sink to cool down IC and it save from damaging. Use capacitors with IC for more stable voltage supply. |
