Duration is the total time to complete a task. The unit of measurement
is hour.
Duration is quite different
to effort, which is the number of person hours to complete a task.
e.g. If a task takes 8 hours to complete, then it has a duration
of 8 hours. If 10 people work on this task for the duration of
8 hours, then the effort is 80 hours. |
| :
Effort is the amount of time it takes one person to do a task.
The unit of measurement is person hour. |
Firewall:
A firewall is a set of related programs, located at a network
gateway server, that protects the resources of a private network
from users from other networks. Basically, a firewall, working
closely with a router program, filters all network packets to
determine whether to forward them toward their destination. A
firewall is often installed away from the rest of the network
so that no incoming request can get directly at private network
resources. There are a number of firewall screening methods. A
simple one is to screen requests to make sure they come from acceptable
(previously identified) domain names and IP addresses. For mobile
users, firewalls allow remote access in to the private network
by the use of secure logon procedures and authentication certificates
(see also Using
MetriQ with a firewall). |
| The duration
of a folder from start to finish. Does not include the time to
set up the folder and assign resources by the manager. |
| Gantt
Chart: A chart (named for Henry Laurence Gantt) that
consists of a bar chart that graphically displays project schedule,
depicting progress in relation to time and often used in planning
and tracking a project. |
| hms:
For brevity, we use hms to represent hours:minutes:seconds in
Reports. Units may also be used within MetriQ where each unit
represents a predefined number of minutes. |
| IP
Address: Network addresses are usually of two types:
(1) the physical or hardware address of a network interface card;
for Ethernet this 48-bit address might be 0260.8C00.7666. The
hardware address is used to forward packets within a physical
network. (2) The logical or IP Address is used to facilitate moving
data between physical networks and is made up of a network number,
a sub-network number, and a host number. |
| IPX:
Internet Packet Exchange. The Novell NetWare protocol that provides
datagram delivery of messages. A built-in networking protocol
for Novell Netware. It was derived from the Xerox Network System
protocol and operates at the network layer of the OSI protocol
model. |
| Linux:
A freely available Unix-like operating system based on a kernel
originally written for the Intel 386 architecture by (then) student
Linus Torvalds. Once his 32-bit kernel was available, the GNU
utilities made it a usable system and contributions from many
others led to explosive growth. Today Linux is a complete Unix
replacement available for several CPU architectures -- Intel,
DEC/Compaq Alpha, Power PC, both 32-bit SPARC and the 64-bit UltraSPARC,
SrongARM, . . . -- with support for multiple CPUs on some architectures.
Linux FreeS/WAN is intended to run on all CPUs supported by Linux
and is currently (February 1999) known to work on Intel, Alpha
and StrongARM |
| Localhost:
A placeholder for the name of the computer on which a program
is running; localhost uses the reserved loopback IP address 127.0.0.1.
|
| NetBEUI:
NetBEUI is short for NetBios Enhanced User Interface. It is an
enhanced version of the NetBIOS protocol used by network operating
systems such as LAN Manager, LAN Server, Windows for Workgroups,
Windows 95 and Windows NT. Netbeui was originally designed by
IBM for their Lan Manager server and later extended by Microsoft
and Novell. |
| Protocol:
A protocol is a standardized means of communication among machines
across a network. Protocols allow data to be taken apart for faster
transmission, transmitted, and then reassembled at the destination
in the correct order. The protocol used determines the way errors
are checked, the type of compression, the way the sender indicates
the end of the transmission, and the way the receiver indicates
that the message has been received. Protocols can describe low-level
details of machine-to-machine interfaces (e.g., the order in which
bits and bytes are sent across a wire) or high-level exchanges
between allocation programs (e.g., the way in which two programs
transfer a file across the Internet). |
| Proxy:
An intermediate server that sits between the client
and the origin server. It accepts requests from clients, transmits
those requests on to the origin server, and then returns the response
from the origin server to the client. If several clients request
the same content, the proxy can deliver that content from its
cache, rather than requesting it from the origin server each time,
thereby reducing response time. (see also Firewall) |
| RDBMS:
Relational Data Base Management Systems (RDBMS) are database management
systems that maintain data records and indices in tables. Relationships
may be created and maintained across and among the data and tables.
|
| Resource Costs are
costs assigned by the Full User when a Folder is being created.
They represent resources, materials, travel and any other such
costs that the user will envisage. |
| MetriQ's patent
pending timing system, gives instant real-time analysis of a Folders
status. |
| Server:
A computer on a network that is dedicated to a particular purpose
and which stores all information and performs the critical functions
for that purpose. For example, a Web server would store all files
related to a Web site and perform all work necessary for hosting
the Web site. Most congressional offices have at least one server
that is dedicated as both a network server and a file server.
This means that, in its network server role, the computer is responsible
for holding the files and managing the processes that enable everyone
in the office to access and use the network. In its file server
role, it holds the central computer files and the CMS database |
| Staff costs are calculated
by multiplying the Staff Pay Rate by the Number of Staffing Effort
Hours. |
| SPX:
A common protocol used on Novell networks. It provides guaranteed
in-order delivery of packets. To accomplish this, it runs on top
of IPX and adds a layer of error correction and resend mechanisms.
SPX typically runs ten times slower that IPX. See also: IPX, Protocols.
|
| Synchronization: Synchronization is the process whereby two identical contact records are kept up to date in two different databases. For example, your company has a Master MetriQ database with all your user folders, clients etc. and you have 3 salespeople who cover three distinct territories, each having a portion of the master database on a laptop. Synchronization would be the process of updating the Master database with any new clients the salespeople obtain and enter into their localized database on their laptop. |
|
TCP/IP: (Transmission Control Protocol/Internet
Protocol) -- This is the suite of protocols that defines the Internet.
Originally designed for the UNIX operating system, TCP/IP software
is now available for every major kind of computer operating system.
To be truly on the Internet, your computer must have TCP/IP software. |
|
A graphical display of time spread across different activities
and Tasks. |
An
autonomous program that works in the background determining when
and where to start and stop timing for a given task (see The
MetriQ Environment). |
| WWW:
Loosely used, the WWW (or Web) refers to the whole constellation
of resources that can be accessed using gopher, FTP, HTTP, Telnet,
Usenet, WAIS, and some other tools. The WWW is a hypertext-based,
distributed information system originally created by researchers
at CERN, the European Laboratory for Particle Physics, to facilitate
sharing research information. The Web presents the user with documents,
called web pages, full of links to other documents or information
systems. Selecting one of these links, the user can access more
information about a particular topic. Web pages include text as
well as multimedia (images, video, animation, sound). Servers
are connected to the Internet to allow users to traverse ("surf")
the Web using a Web browser. |
Virtual Private Network:
The world has changed a lot in the last couple of decades. Instead
of simply dealing with local or regional concerns, many businesses now
have to think about global markets and logistics. Many companies have
facilities spread out across the country or around the world, and there
is one thing that all of them need: A way to maintain fast, secure and
reliable communications wherever their offices are.
Until fairly recently, this has meant
the use of leased lines to maintain a wide area network (WAN). Leased
lines, ranging from ISDN (integrated services digital network, 128 Kbps)
to OC3 (Optical Carrier-3, 155 Mbps) fiber, provided a company with a
way to expand its private network beyond its immediate geographic area.
A WAN had obvious advantages over a public network such as the Internet
when it came to reliability, performance and security. But maintaining
a WAN, particularly when using leased lines, can become quite expensive
and often rises in cost as the distance between the offices increases.
As the popularity of the Internet grew,
businesses turned to it as a means of extending their own networks. First
came intranets, which are password-protected sites designed for use only
by company employees. Now, many companies are creating their own VPN (virtual
private network) to accommodate the needs of remote employees and distant
offices.
A typical VPN might have a main LAN at the corporate headquarters of a
company, other LANs at remote offices or facilities and individual users
connecting from out in the field.
Basically, a VPN is a private network
that uses a public network (usually the Internet) to connect remote sites
or users together. Instead of using a dedicated, real-world connection
such as leased line, a VPN uses "virtual" connections routed
through the Internet from the company's private network to the remote
site or employee. In this article, you will gain a fundamental understanding
of VPNs, and learn about basic VPN components, technologies, tunneling
and security. Courtesy http://computer.howstuffworks.com/vpn.htm
