Sociology - Wal-Mart - Essay Example Eventually, the only thing that is left is Wal-Mart, and the people have no choice left but to shop there. This can cause an effect similar to a monopoly in a small town. People may have no stores for miles except for Wal-Mart because ever place has had to close because it couldn't compete with Wal-Mart. This then leaves people with no choice BUT to shop at Wal-Mart, and this only continues the vicious cycle elsewhere in other small towns. This can cause devastation effects on a town's economy. Wal-Mart then becomes the ONLY major player still in the economy of a town. This not only puts small stores out of jobs, but gets rid of the basis for all business, competition. This can then lead to Wal-Mart business policies becoming lax, as they no longer have to compete and now are the only game in town. The entire point of business is to have competition, but Wal-Mart makes sure to destroy all competition it can have early on. Wal-Mart also has many problems that go deeper than just the problems after the store comes in. If everybody who shopped at Wal-Mart sat down and watched this movie about how bad Wal-Mart treats its employees, and the poor wages that the corporation tries to pass by. Examples are given of major sexism against women, and how unfairly the Wal-Mart Corporation treats women.

Number Systems - Coursework Example In this system, 0 is called as the Least Significant Bit (LSB) while 1 is called the Most Significant Bit (MSB). Binary system is the computer language by default because 0 and 1 in computer signify voltage positions of on and off. Hexadecimal system uses base-sixteen system for computing. It has 16 digits but since numbers are only from 0-9, letters are also termed as valid hexadecimal digits (Ratzan 18). As such, letters from A to F are included in hexadecimal system after counting 0-9 where A stands for 10, B for 11 and so on. In this system, one digit is equivalent to 4 bits. Inter-relationship of these three systems is depicted in Appendix 1. When converting from decimal to hexadecimal, the same rule of successive divisions is followed as mentioned above. When reverse is done, same power raising method is used but now with 16 as the base and place values as exponents. In this conversion, the binary digit is grouped in blocks of four, starting from right hand. Additional zeroes are added to the left to complete the grouping. After grouping is completed, corresponding hex digit for binary blocks is noted down from the conversion table. For example, (0010101001)2 comprises of 10 bits. Thus we have to add two additional zeroes to its left to complete blocks of 4. Addition and subtraction of 2’s complement is actually always addition, just the subtrahends are converted to their negative forms when carrying out subtraction. In binary form, leftmost digit 1 represents a negative number while leftmost digit 0 represents a positive number. Let’s have a look at the addition and subtraction of 2’s complement (Finley
