Answers
The computer does its work in a machine called CPU (Central processing Unit) that converts data input to information output. Is a circuit that executes stored program instructions. All computers, large and small, must have a central processing unit(CPU),The CPU have two parts: control unit and the arithmetic/logic unit.How Computers Work...The program instructions and data are placed in memory from an input device or a secondary storage device once the data and instruction are in memory, the CPU performs the steps for each instruction: The control unit gets the instruction from memory.The control unit decodes the instruction and directs that the necessary data be moved from memory to the arithmetic/logic unit. These first two steps together are called instruction time, or I-time.The arithmetic/logic unit executes the instruction. That is, it performs the operation on the data.Thc arithmetic/logic unit stores the result of this operation in memory or in a register. The control unit directs memory to release the result to an output device or a secondary storage device. The combination of I-time and E-time is called the machine cycle. Advantanges of Computer.Access huge amount of information that is available on the internet. Allow us to analyze data very quickly, saving both time and money.With computers and the internet, businesses can sell their products to people far from where they are.It has the time saving nature.Using the computer save natural resources by limiting our need of paper and pencils.Increases the productivity.Can store vast amounts of information and reduce waste.DisadvantagesThey are addictive. computers creates problem when they break down. Many people do not know how to fix them and have to take them to be repaired.Computers uses a great deal of Power that is electricity and they can be dangerous when disposed of improperly.
