application window

The main window for an application, which contains the application's menu bar and work area. An application window may contain multiple file windows.


arrow keys

The arrow keys are used to navigate around your screen. Each key is named for the direction the arrow points. There is an UP ARROW, a DOWN ARROW, a LEFT ARROW, and a RIGHT ARROW key.


ASCII

An acronym for American Standard Code for Information Interchange, a coding scheme that assigns numeric values to letters, numbers, punctuation marks, and certain other characters. By standardizing the values used for these characters, ASCII enables computers and computer programs to exchange information.


attributes

Information that indicates whether a file is a read-only, hidden, or system file, and whether the file has been changed since a backup copy of it was made.


Back button

Goes back to the Help topic you have just viewed. Use this button to backtrack through the topics you have viewed so far. The Back button is in the Help button bar near the top of the Help window.


branch

A segment of the directory tree, representing a directory and any subdirectories it contains.

CRC

An abbreviation for cyclical redundancy check, a procedure used by communications protocols in checking for data transmission errors. CRC error checking uses a complex calculation to generate a number based on the data transmitted. The sending device performs the calculation before transmission and sends its result to the receiving device. The receiving device repeats the same calculation after transmission. If both devices obtain the same result, it is assumed that the transmission was error free. The procedure is known as redundancy checking because each transmission includes not only data but additional error-checking values.


current address

A network address that is assigned to the network card by software on the computer, overriding the permanent address for most purposes.


default button

Ethernet

A widely implemented LAN from which the IEEE 802.3 standard for contention networks was developed. Ethernet uses a bus topology and relies on the form of access known as CSMA/CD to regulate traffic on the main communication line. Network nodes are connected by either thin or thick coaxial cable, or by twisted-pair wiring. Information on an Ethernet network is sent in variable-length frames containing delivery and control information plus up to 1500 bytes of data.

group

A collection of related options in a dialog box.


Help button bar

Contains the Help buttons you can use to move to topics. It is located near the top of the Help window.


hexadecimal

The base-16 number system that consists of the digits 0 through 9 and the uppercase or lowercase letters A (equivalent to decimal 10) through F (equivalent to decimal 15). Hexadecimal, usually called hex, is commonly used in programming as a compact means of representing the binary numbers used internally by a computer. Hexadecimal is particularly useful because it fits neatly into the 8-bit bytes on which computer memory and storage are based. Because any of 16 digits can be represented in 4 bits, two hexadecimal digits (one for each 4 bits) can be represented in a single byte.


highlighting

A means of selecting characters on a screen to display them in a different color or intensity.

From the address list, you can sort the address database by either the network address, computername, or comment field.


address pair

The source and destination addresses involved in a data transmission. The destination can be a single address, multicast, or broadcast. In captured data, the source address is a specific address. In filter specifications, the source address can be a specific address or it can be Any, but cannot be broadcast or multicast.


Summary pane

The pane in a Frame Viewer window that lists the frames contained in the capture file. This pane lists, for each frame:  the frame number, the time the frame was captured, the source and destination addresses of the frame, the protocols that were used to send the frame, and a brief description of the frame.  In addition, if a raw address also has an associated IP or IPX/XNS address, these addresses are displayed in the Src Other Addr, Dst Other Addr columns. The address type (IP or IPX/XNS) is displayed in the Summary pane's Type Other Addr column.

When a frame in the Summary pane is highlighted, the associated data in the Detail and Hex panes is also highlighted.


Detail pane

The pane in the Frame Viewer window that gives detailed information about the protocol properties in the frames included in the capture file.

You can view more or fewer fields by expanding or collapsing the listed protocols, or by adjusting the protocol levels through the Protocol Levels/Colors dialog box.

By default, this pane appears as the center pane in the window.


Hex pane

The pane in the Frame Viewer window that shows the hexadecimal bytes transmitted in frames included in the capture.

By default, this pane appears at the bottom of the window.


capture file

decision tree

A query-like structure graphically represented in the main window of the Capture Filter and the Display Filter dialog boxes. In a decision tree, statements are linked together by colored AND, OR, and NOT tabs. Combined, these statements specify the kinds of data you want to capture or to display in the Frame Viewer window.


packet

Also called a frame. A package of information transmitted as a single unit over a network. Every frame follows the same basic organization and contains control information, such as synchronizing characters, station address, and an error-checking value, as well as a variable amount of data.


secondary mouse button

data stream

The sum of the traffic travelling across the network at a given time.


floating menu

A menu that appears in a window and that is not attached to a menu bar.


contention

Competition among computers for the opportunity to use a communications line or network resource. Contention describes a situation in which two or more workstations attempt to transmit at the same time, thus causing a collision. Contention also describes a free-for-all method of controlling access to a communications line, in which the right to transmit is awarded to the computer that wins control of the line. In this type of contention, each computer listens to the line and waits for it to become inactive. When the line is free, any computer that wants to transmit bids for the line by sending a request-to-send message to its intended recipient. If the response is positive, the computer is free to transmit, and all other computers must wait until the line is free again before attempting any transmission of their own.


Network Monitor Agent

A component that resides on a Windows NT computer and that enables that computer to be used remotely to capture data from the network.  When a Systems Management Server Network Monitor installation connects remotely to the Network Monitor Agent and initiates a capture, statistics from the capture are transferred over the network to the managing computer at intervals specified when the connection is made.

Windows NT Server Network Monitor cannot capture remotely.


topology header

The section of a frame that is added by the networking topology. For example, on an Ethernet network, 14 bytes are added to the frame at the Ethernet layer. In a TokenRing environment, the number of bytes varies.


dedicated capture mode

A Network Monitor capture option that is designed to conserve system resources and to minimize the number of frames dropped. When you use dedicated capture mode, capture statistics are not displayed or refreshed as the frames are copied to the capture buffer.


counter

A mechanism used by the Windows NT Performance Monitor to graphically log the behavior of any system resource or process over time. For example, one of the Performance Monitor counters provided by Network Monitor is called "Total Bytes." It describes the total number of bytes travelling over the network per second.


sublayer

A layer within one of the layers defined in the OSI model. A sublayer is designed to accomplish part of the overall purpose of the layer of which it's a component. For example, the Data Link Layer, which is responsible for checking the data consistency of frames and of ensuring the safe delivery of frames from one node to another, consists of the Logical Link Control (LLC) and Media Access Control (MAC) sublayers. The LLC sublayer establishes and maintains the link between two network nodes. The MAC sublayer controls access to the transmission medium and detects data collisions.


per second statistics

The statistics in the Capture window that represent the average amount of data captured by Network Monitor every second.


capture buffer

A reserved area in memory into which Network Monitor copies captured frames. The size of the capture buffer can be increased to the amount of memory available on a system. When the Systems Management Server Network Monitor remote agent is used to capture on a remote computer, the size of the capture buffer is limited to the amount of memory available on the remote computer.

Windows NT Server Network Monitor cannot capture remotely.
