C. The amplitude changes over time. 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose tow answers.)
Continuity Tester - is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. 13. Category 5e/6 Cable - is a twisted pair cable for carrying signals/ is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the
Pentium Flaw Intel was founded in July 1968 by American engineers Robert Noyce and Gordon Moore. Their Pentium microprocessor was first introduced in 1993. The Pentium was the first Intel chip for PC’s to use parallel processing, which significantly increased its speed. It had 3.1 million transistors on one chip, compared to its predecessor the 80486 with 1.2 million transistors per chip. In 1994 the public began to notice a flaw.
What 3 things do electronic hardware devices need in order to function? 1. A method for the CPU to communicate with the device 2. Software for instruction 3. Electricity for power 5.)
5. Tin's actual atomic radius is 140 pm. Use the math equation below to determine the percent error of your estimated value. (140-145) x100 = 3.5 140 1. The atomic radius you estimated from your graph is most likely not exactly the same as the true atomic radius of tin.
What are limitations of these three file systems? 1. Ntfs- names limited to 255 utf – 16 code words / maximum volume size / maximum file size 2.Fat- clusters can’t be 64 kb / must contain 65,527 clusters 3. Hpfs under 200 mb large 400 mb some performance degradation. What is windows registry, and what is its purpose?
1. What is an ultracapacitator? Device used for storing electrical energy 2. What Carnegie Mellon University professor was the first person to use :-) as a horizontal smiley face in a computer message in 1982? Scott E. Fahlman 3.
6. Briefly explain how nuclear fuel is converted to electrical energy in a nuclear power plant. In a nuclear-fueled power plant, water is turned into steam, which in turn drives turbine generators to produce electricity, and the heat to make the steam is created when uranium atoms split, which is known as fission. 7. How is radon harmful to people?
The first 286 pedaled along at 6MHz and, like the original 8086, would later double in speed. However, clock for clock, the 286 boasted twice (or more) the performance of the 8086, a generational leap in the x86 architecture that has never been duplicated to this day. Throughout the decade, the 286 became synonymous with IBM PCs, and within 6 years of its release, Intel estimates there were 15 million 286-based PCs installed worldwide. The 386, which was later named 386DX to avoid confusion with a lower cost 386SX variant that would debut three years after launch, initially ran at 16MHz and, once again, would eventually double in speed to 33MHz. It also doubled the number of transistors from its predecessor to 275,000 and was Intel's first 32-bit processor.
Project Report Spin Transport in Semiconductors EE-453 U1 Group Members: Fatemah AlSejari- 17429 Fatema AlMuteiry-15020 Spin Transport in Semiconductors Introduction Semiconductors are special materials that have diffusive and drift current, that there is a significant interaction between a diffusive spin current and a drift charge current. In semiconductors such as silicon the electrochemical potential (μ_Spin) of the spin is not constant through the material. The spin accumulation considered as a function of magnitude at each point. Because of that, there are many features of the spin transport in semiconductor such as spin conversion between drift and diffusion currents, and a gain/damping of the spin current by a charge current.
