Answer is Wrong!
The correct answer is C. CPU. A CPU is a Central Processing Unit, which is the main processor in a computer. It is not a method of accessing the web.
A modem is a device that converts digital signals from a computer into analog signals that can be transmitted over a telephone line. ISDN is a type of digital subscriber line (DSL) that provides high-speed Internet access over regular phone lines. DSL is a type of broadband Internet access that uses existing phone lines to deliver high-speed data.
