My Slow Computer..At Ma House

I think that my computer is really slow...I dont know why, but it just is..Mr.West told my class how you can tell how fast and slow our computer is. He gave us all these tech words that we need to know about a computer..my computers OS Name is Microsoft Windows XP Home Edition, my Processor is 1803 MHz..which to me sounds really slow. My total physical memory is 512.00MB, total avaibile physical memory is 79.68 MB, and total virtual memory os 2.00MB. My computer is slow and i no it, but i might clean some stuff out of it, like Mr.West shown us.
