• Healthcare and the arts
• Computer simulations
• ## The Integrated Circuit (IC)

• First developed in the late 1950’s
• ## Understanding of fundamental concepts

• Once understood, will not be replaced • ## Stephen Gray (transmitted electrical charge over long distances on silk thread) • ## Alessandro Volta – 1799 (voltaic cell) • ## Wilhelm Röntgen – 1895 (X ray) • ## Aleksandr Popov – first radio message

• “Heinrich Hertz”

• ## Lee De Forest – 1906 (first amplifier) • ## Color television – 1960s • ## ENIAC – 1946 University of Pennsylvania • ## Bell Telephone Laboratories –1947

• Point-contact transistor

• ## First commercial grade IC – 1961 - Fairchild Corp. • ## If a unit of measurement is applicable to a result or piece of data, then it must be applied to the numerical value • ## The proper unit of measurement is applied to the result • ## The standards of some units are quite interesting

• Meter
• Kilogram • ## When writing numbers, consider:

• format used
• number of digits being included
• unit of measurement to be applied

• ## Rounding off numbers • ## Powers of 10

• 1=100 1/10 = 0.1 =10-1
• 10 =101 1/100 = 0.01 =10-2
• 100 =102 1/1000 = 0.001 =10-3
• 1000 =103 1/10,000 = 0.0001 =10-4 ## Powers of Ten

• When adding or subtracting numbers in a powers-of-ten format, be sure that the power of ten is the same for each number. Then separate the multipliers, perform the required operation, and apply the same power of ten to the result • ## Multiplication

• When multiplying numbers in the powers-of-ten format, first find the product of the multipliers and then determine the power of ten for the result by adding the power-of-ten exponents • ## Division

• When dividing numbers in the powers-of-ten format, first find the result of dividing the multipliers. Then determine the associated power for the result by subtracting the power of ten of the denominator from the power of ten of the numerator • ## Powers

• When finding the power of a number in the powers-of-ten format, first separate the multiplier from the power of ten and determine each separately. Determine the power-of-ten component by multiplying the power of ten by the power to be determined • ## Fixed-Point, Floating-Point, Scientific, and Engineering Notation

• There are generally four ways in which numbers appear
• Fixed-point
• Floating-point notation
• Scientific (standard) notation
• Engineering notation • ## Prefixes

• Specific powers of ten in engineering notation have been assigned prefixes and symbols • ## Convert kilometers (km) to millimeters (mm) • ## Perform the required mathematics to obtain the proper magnitude for the remaining unit of measurement ## 1.10 Symbols • ## Anticipatory thinking will eliminate the possibility of mistakes • ## Initial settings

• Format and accuracy
• ## Order of operation • ## Language

• C++, Basic, Pascal, and Fortran
• ## Software packages Yüklə 462 b.
