TAILIEUCHUNG - Lecture Network Certification: Chapter 17 - Microsoft Press

Chapter 17 - Network troubleshooting procedures. Chapter summary: Computers have a variety of ports, some of which are implemented by the motherboard and others by expansion cards; computers use many different types of connectors fortheir various interfaces, and in some cases the same connector type can provide different functions; SCSI host adapters can use any one of several types of connectors, which are not interchangeable;. | Chapter Overview Identifying Network Components Troubleshooting a Network Locating Ports The ports on a typical computer are located either on the motherboard or on expansion cards that plug into the system bus. If the same type of port can have more than one function, you can sometimes tell what a port does by where it is located. The locations of the motherboard ports vary, depending on the design of the computer.
