    1. Workstation Equipment

    3. KVM Switch What does KVM stand for? Keyboard, Video, Mouse

    4. How does a KVM Switch work? Control between computers is switched between devices connected with a KVM switch. The KVM passes the signals between the computers and the keyboard, mouse, and video. Devices differ in the number of computers that can be connected. In Lab 136 four computers can be connected.

    5. KVM Switches Useful when there are multiple computers that need to be connected, but no need for additional keyboards, mice, and monitors. Frequently used in server racks Data centers PC repair shops

    6. When purchasing a KVM switch… How many computers will you be connecting? How and where will the KVM switch be mounted? Do the computers have PS2 (purple and green connectors on back of the computer) or USB ports for keyboard and mice connectivity?

    7. PS2 Connectors The name PS2 comes from the IBM Personal System/2 a series of personal computers back in 1987.

    9. NETGEAR GS605 Five Ports (1 – 5) on the front Link, Speed, and Activity indicators Auto negotiates between 10/100/1000 Mbps (In other words senses the right speed and whether a device is full or half duplex mode.) Plug and Play Technology

    12. Half Duplex Provides communication in both direction, but only one direction at a time. Typically when one device is receiving a signal it must wait for the transmitter to stop transmitting before replying An example: ?

    13. Half-Duplex Walkie-Talkie

    14. Full-Duplex Allows communication in both directions simultaneously. Example: ?

    15. Full-Duplex Telephone (Both Land Line and Mobile) Two way radios can be designed as full-duplex whereby they transmit on one frequency and receive on a different frequency.

    16. Full-Duplex Connections Ethernet connections work by making simultaneous use of all four physical pairs of twisted cable. Two pairs are used for receiving packets Two pairs are used for sending packets Benefits of full duplex: no wasted time no retransmitting of frames, because there are no collisions
