American History - Essay Example Through speeches and demonstrations, black Americans to a considerable extent had their grievances heard. Among such blacks include; Booker T. Washington whose accommodative perspective as witnessed in his famous speech delivered in 1895 at the Cotton States Exposition in Atlanta fundamentally appealed for the understanding of the significance of the mutual relationship between blacks and whites which was popularly termed as The Atlanta Compromise while Stokely Carmichael who while at Howard University became the chairman of the Student Nonviolent Coordinating Committee, that later changed its goal to a violent organization that could be used to forcefully address issues faced by black Americans gave rise to the famous slogan of The Black Power. This paper, through the analysis of Washington The Atlanta Compromise and Stokely’s The Black Power seeks to illustrate the differences, similarities, goals, and perceptions towards members of the white community by these two famous pe ople within the context of American history. In the famous Atlanta Compromise address, Washington underscores the essence of a friendly relationship between the whites and blacks.... He emphasized on the need to cultivate friendly relations between blacks and whites across all professions, be it in mechanics, agriculture, domestic service, and in commerce. Washington passionately appealed to the black Americans never to permit their grievances to overshadow their opportunities through asserting that meaningful life ought to progress from the bottom and not the top. He primarily underscored the need for a compromise between the black and white communities in order to attain common consensus in decision making. Just in the same way he reprimanded his fellow members of the black race, Washington conveyed the same message to the whites, â€Å"To those of the white race who look to the incoming of those of foreign birth and strange tongue and habits of prosperity of the south, Cast down your bucket where you are† (Booker 28). From the Atlanta Compromise speech, it is apparent that blacks while serving as slaves to whites, they did it honestly and diligently. Th is is expressed in his own appeal â€Å"†¦ Negroes whose habits you know whose fidelity and love you have tested in days when to have proved treacherous meant the ruin of your firesides, cast down your bucket among these people who have, without strikes and labor wars, tilled your fields, cleared your forests, build your railroads and cities,† (Booker 28). According to Washington, blacks in essence have the most beneficial characteristics that the white community had to tap. He describes blacks as being the most patient, faithful, law-abiding, and unresentful group of people that the world has seen (Booker 28). He appeals to the white community while guaranteeing that this relationship between

Investigate data representations - Essay Example The above scheme can work fine as long as there are â€Å"unsigned† numbers. A strategy had to be evolved to represent â€Å"signed† numbers with consistent representation of negative as well as positive numbers. Several representation systems exist to represent signed numbers like the sign-and-magnitude, one’s complement, two’s complement, etc. Sign-and-magnitude and one’s complement both use the most significant bit to represent the sign of the number with 0 for positive and 1 for negative sign. An anomaly arises in the representation of the number zero itself. Since the most significant bit denotes the sign, a zero can be both â€Å"negative†, as in 10000000, as well as â€Å"positive†, as in 00000000. This ambiguity has led modern computer systems design to adopt the two’s complement which does not have this ambiguity. Two’s complement represents positive numbers by converting simply from decimal to binary. So, a decimal 4 in 4-bit representation would become 0100. Zero is uniquely represented by 0000. Negative numbers are first complemented and then a 1 is added to the result. A generic formula would be 2N-A+1 where N is the number of bits used and A is the number to be converted. See example of converting decimal -3 to two’s complement below: Arithmetic functions can be purely addition based and no subtraction remains necessary. Subtraction can be performed by adding the two’s complement representations. The resulting number is the two’s representation of final result. The range of uniquely representable numbers in N-bit systems are -2N-1 to +-2N-1-1 (Dandamudi 886). Floating point numbers are represented differently. They are divided into three parts, the sign bits for exponent and mantissa, the exponent and the mantissa. For example, if 205.347 is to be represented, it is first brought to a â€Å"normal form† of 2.05347 x 102 where 205347 is the mantissa and the power of 2 is the
