It is when a single company has control of a certain commodity or service.
Freedmen's Bureau, during the Reconstruction period after the American Civil War, popular name for the U.S. Bureau of Refugees, Freedmen, and Abandoned Lands, established by Congress to provide practical aid to 4,000,000 newly freed African Americans in their transition from slavery to freedom.
Explanation:
- The Freedmen's Bureau provided food, housing and medical aid, established schools and offered legal assistance. It also attempted to settle former slaves on land confiscated or abandoned during the war.
- Despite handicaps of inadequate funds and poorly trained personnel, the bureau built hospitals for, and gave direct medical assistance to, more than 1,000,000 freedmen. More than 21,000,000 rations were distributed to impoverished blacks as well as whites.
- Less success was achieved in civil rights, for the bureau’s own courts were poorly organized and short-lived, and only the barest forms of due process of law for freedmen could be sustained in the civil courts. Its most notable failure concerned the land itself.
- The Freedmen’s Bureau , a government agency established to aid former slaves, oversaw some 3,000 schools across the South, and ran hospitals and healthcare facilities for the freedmen.
Using the bitwise AND operation, the result of 1 AND 0 is 0.
10100100 XOR 11010101 = 01110001.
A common way to detect whether a value is even or odd is to use the AND 1 operation to test if the least significant bit is set.
Combining multiple flags into a single variable can be accomplished via the OR operation.
