A:Answer Thanks for your question. A Toshiba laptop featuring an Intel Core i processor will generally run faster and more efficient than a Toshiba laptop featuring an Intel Celeron processor. You will be able to open programs faster and multitask more efficiently with a Core i processor. You will also generally experience better battery life with a laptop running a Core i processor over a laptop running an Intel Celeron processor. However, if you are looking for a laptop for basic tasks like surfing the web, Microsoft Office applications, online banking, etc. the Intel Celeron processor will perform just fine.
