How do you set up a ping pong net?
Measure 5.3" up from the base.
You must screw it on the table. You want to make sure it is straight up and down and that it is right in the middle of the table.
What is the tap off in cable network?
Tap off in cable networks is a point in the network where a branch cable is connected in order to connect a customer or a subscriber. It is usually done by a splitter or a coupler. Tap off points are also used to measure the signal strength or to monitor the quality of the transmission. The tap off point is usually connected from the main trunk cable to the side branch cable. Tap off points are also used to connect amplifiers and other devices in the network.
- Tap off points are used to connect branch cables to the main trunk cable.
- Tap off points can be used to measure signal strength or monitor transmission quality.
- Amplifiers and other devices can be connected to tap off points.

What is a characteristic of Spanning Tree Protocol?
A spanning tree protocol, or STP, is characteristic to a LAN. It provides a loop-free topology for networks within the system.

it is a MAC Media acces control each network adapter on you adapter has a uniquie number (like a serila number) assigned to it by the manufactor.
What is handshaking in networking?
A handshake in networking happens when a computer wants to talk to another computer. Before anything is sent and received the hand shake takes place. This example is from the TCP protocol: Machine 1 sends a SYN packet to Machine 2 Machine 2 sends a SYN/ACK back to Machine 1 Machine 1 sends an ACK back to Machine 2 SYN = Synchronise ACK = Acknowledge
a computer network in which devices are connected through copper wire cables
What is OLP in server license?
OLP = Open License Program Microsoft Open License is a Volume Licensing program for small to midsize organizations that have fewer than 250 desktop PCs. The program provides a simple, flexible, and cost-effective way to buy the latest Microsoft technology to meet your organization's needs and procurement procedures. http://www.microsoft.com/licensing/programs/open/default.mspx NL = No Level
Some Microsoft Volume License programs have "Levels", which are basically bulk discounts. Some other companies call these "price bands". Depending on the number of licenses purchased at once, discounts get applied. If you don't purchase enough for a discount, this is called No Level or NL.
For example:
Microsoft Exchange Server 2007 Standard CAL has two discount Levels: No Level - for 1 to 49 users Level C - for 50+ users
Are the distinct units of the data that are exchanged between nodes on a network?
Data packets

What is the maximum effect of 2 ms burst of noise on data transmitted at 1500 bps?
We can say that :
Vulnerable bits = data rate x burst duration
= 1500 x 2 x 10^-3 = 3 bits
What is the purpose of the TCP three way handshake?
The three-way handshake in Transmission Control Protocol (also called the three message handshake) is the method used to establish and tear down network connections. This handshaking technique is referred to as the 3-way handshake or as "SYN-SYN-ACK" (or more accurately SYN, SYN-ACK, ACK). The TCP handshaking mechanism is designed so that two computers attempting to communicate can negotiate the parameters of the network connection before beginning communication. This process is also designed so that both ends can initiate and negotiate separate connections at the same time.
Ipconfig is used to show all current TCP/IP network configurations values and connections in Microsoft Windows. It is a command line tool.

A gateway is a node (a router) on a computer network that serves as an access point to another network.
A Default Gateway is the node on the computer network that is chosen when the IP address does not belong to any other entities in the Routing Table. In homes, the gateway is usually the ISP-provided device that connects the user to the internet, such as a DSL or cable modem. In enterprises, however, the gateway is the node that routes the traffic from a workstation to another network segment. The default gateway is commonly used to be the node connecting the internal networks and the outside network (Internet). In such a situation, the gateway node could act as a proxy server and a firewall. The gateway is also associated with both a router, which uses headers and forwarding tables to determine where packets are sent, and a switch, which provides the actual path for the packet in and out of the gateway. In other words, it is an entry point and an exit point in a network.
