7. A type of KVM switch that is controlled through a mechanical switch on the box.






8. In Windows - an Advanced Options menu choice that starts Windows without several drivers and components and loads only very basic - non-vendor-specific drivers for mouse - video - keyboard - mass storage - and system services. Safe Mode also displays






9. The read-only DVD discs sold at retail stores - containing video or software and having a maximum capacity of 15.9 GB of data. This term also applies to the drives that can only read DVDs.






10. The amount of data that can travel over a network at a given time.

23. A TPM is a special microchip - installed on a motherboard - that stores passwords - keys - and digital certificates. Various services - such as BitLocker can store such security data in this chip.






24. Aka motherboard.






25. A communications network made up of personal computing devices - such as computers - telephones - and personal digital assistants.






26. A remote KVM switch that uses either Cat 5 or USB cabling. The distance it can be from the computers it controls is a function of the length limits of the cabling; it normally uses a proprietary protocol and special hardware.






27. Video RAM memory that uses a technique for using video RAM to perform Windows-specific functions to speed up the OS.






28. Aka Scalable Link Interface.






29. A WAN connection that uses existing copper telephone wire for the communication circuit. To accomplish this - a DSL modem splits the existing phone line into two bands; voice transmission uses the frequencies below 4000 Hz - whereas data transmission






30. The bus within a CPU that connects the CPU to external components.






31. A partition type that can exist on a basic disk and have one or more logical drive letters assigned to it. A Windows operating system cannot boot from an extended partition.

42. In a CPU - the speed at which it can potentially execute instructions - measured in millions of cycles per second






43. A firewall service that inspects (or filters) each packet that enters or leaves the network - applying a set of security rules defined by a network administrator - and not allowing packets that fail inspection to pass between networks.

49. Aka Wireless Fidelity.






50. A network device that is used to extend the range of a network by taking the signals received on a port from one network and regenerating (repeating) those signals to another port to transmit them on a second network.
