Yes, or you can go to a college or university bookstore and buy their computer books. They have a wide range to choose from including huge thick ones that will teach you everything you need to know to take the MCSE, A+, CCNA/CCNP (Cisco), Network +, etc. I still have muy original book on computer troubleshooting (A+ Certified) and it is a great text.
