Imagine you and your friends are all selling toys. Each of you has a certain number of toys that you sell, and together you make up the total number of toys sold. This is kind of like how personal computer vendors work!
Personal computer vendors are companies that make and sell computers, like Dell, HP, and Apple. They all sell computers and together they make up the total number of computers sold, kind of like how you and your friends make up the total number of toys sold.
Market share is like a way of measuring how much of the toy selling market you and your friends have. In the case of personal computer vendors, market share measures how much of the computer selling market each company has.
For example, let's say there are 100 computers sold in a month, and Dell sold 40 of them, HP sold 20, and Apple sold 40. Dell's market share would be 40%, HP's market share would be 20%, and Apple's market share would be 40%.
This information is useful for the computer companies because they can see how they compare to their competitors. They can see if they are selling more or less computers than the other companies, and they can try to improve their products or marketing to increase their market share.
In the end, the market share of personal computer vendors is just a way of measuring how much of the computer selling market each company has, kind of like how you and your friends measure how much of the toy selling market you have.
