What features do you personally find most important, and which model would serve those needs best? Sharing Wi-Fi Suppose your family pays for broadband Internet service, and you have a wireless router that allows everyone in the family to share the Internet connection. The wireless router has security on it, so that a code is required to connect to it. This prevents your neighbors from using your Internet connection without permission. A neighbor asks for the code so he and his family can use your Internet connection.

There are many different registers, each with its own special purpose. For example, there are registers that hold data, registers that hold instructions, registers that store logical states (yes/no), temporary values that serve as increment counters, and so on. Physical Composition of a CPU semiconductor Material that is electricity-neutral, neither a good conductor nor a flow preventer. Physically, a CPU is a very small and thin sheet of semiconductor material (usually silicon) with a complex array of tiny transistors and buses stamped into it with a die.

Dynamic memory Memory that does not retain its data unless it is constantly electrically refreshed. static memory Memory that retains its data without electricity being constantly applied. Random Access Memory (RAM) Memory that can have its values changed freely, an unlimited number of times. Read-Only Memory (ROM) In general, memory that cannot be rewritten. However, there are exceptions to that in newer types of ROM. How Computers Use Memory Computers use different types of memory in various ways.
