Question and answer
Explain the impact of evolution of computers hardware and accompanying evolution of operating systems software?
In many ways, computer hardware and operating systems grow together - changes in hardware have to be accomodated by changes in the operating system to support them, [ [ conversely the way the operating system uses the hardware may well influence hardware designers to improve aspects of their work. Example When Windows XP was released, DVD writers were fairly rare and expensive devices and XP
did not directly support them; third party writing software had to be used. When Vista was released, the operating system accomodated the new hardware. Conversely, Windows computers rely heavily on DirectX technology for graphics. Video adaptor designers specifically try to make their devices so they run DirectX well. Computer companies such as IBM and Apple produce both the computer and the operating systems, so they can more tightly couple the two together for simpler operation ] ]

What is your expository essay topic?Negative effects divorce has on children. Why did you select this topic? Why is this topic important for your audience?

Compared to children from homes disrupted by death, children from divorced homes have more psychological problems. (Robert E. Emery, Marriage, Divorce and Children?s Adjustment?

Your body uses good healthy food to create the energy needed for you to move around, work and enjoy life. The fruits, vegetables, meats and fish that you eat on a regular basis all provide your body with what it needs through the nutrients they contain. Energy by definition is the ability to do work. Your body takes the foods you eat and breaks them down so that their stored energy can be used on a daily basis. The amount of energy that a food provides is measured in the number of calories that it contains. The more calories means the more energy available. This is important because is affects the wellbeing of everyone. Everyone needs to eat, and by expressing how to do so to others may contribute to the wellbeing and health benefits for them as well.
