Government tenders & Online tenders
Tender refers to the process that Governments invite bids for their projects. Every tender has a deadline that any company participating in tender should send its proposal before that deadline. Tendering is expression of interest or making a proposal in response to invitation for tender that is announced by Governments, Funding Agencies or Private Buyers and Tender Holders.
Bidding source is an online tenders information Center that provides World government tenders information to all companies in all business fields across the world. Bidding Source helps companies to find business opportunities. Competitions among companies are so hard that without using tenders services they will lose many opportunities for their business. All government tenders are gathered from all countries and published in Bidding Source website every day. We have various teams in different countries that work on gathering this information. All online tenders information is processed and categorized by information processing professionals and finally published by publishing team on Bidding Source international portal.
Tenders information is gathered from newspapers, thousands of online websites… and there is some special information that we receive directly from companies for publishing on Bidding Source website.
Below we try to give more information about Tendering process.

E-mail, short for electronic mail and often abbreviated to e-mail, email or simply mail, is a store and forward method of composing, sending, receiving and storing messages over electronic communication systems. The term "e-mail" (as a noun or verb) applies both to the Internet e-mail system based on the Simple Mail Transfer Protocol (SMTP) and to X.400 systems, and to intranet systems allowing users within one organization to e-mail each other. Intranets may use the Internet protocols or X.400 protocols for internal e-mail service supporting workgroup collaboration. E-mail is often used to deliver bulk unsolicited messages, or "spam", but filter programs exist which can automatically delete some or most of these, depending on the situation.
Different kinds of Email
What are all these "free email" services I see on the Internet and just what is the difference between these and the email account I have now?
There are four kinds of email:
ISP based email
Juno
Internet based
Forwarding
ISP based email
-- The first, the most basic, and what you are now using is most likely ISP based email. ISP (Internet Service Provider) email is the email that you get from the service you use (like AccessFlorida.net or the much more expensive other guys like AOL, Earthlink, AT&T, etc.) to access the Internet. This kind of email service requires that you set up your computer to check this account. Specifying and setting up such things as a POP3 (simply means Post Office Protocol) your incoming mail server and a SMTP (Single mail Transfer protocol) your outgoing mail server. (See the tutorial regarding setting up your email.)
Drawbacks - If you wanted to check your email and you were not at home or at your terminal at work, you would have to change the email set up on the computer you are on, just to check your mail and then change it back to the original user's configuration. Easy to check at home or work, very troublesome to check from somewhere else. This email account is tied to the service you use. Your employer may also assign you an email account. In either case, if you change ISP's or change jobs, your email account is lost. You now need to get a new email account and notify all friends and family of your address change. Always a hassle.
Juno was the best deal I know of if you just want email and not bother with the Internet. It used to be free, now they charge a small fee. You get a local phone number to dial (no long distance charges). The only requirements are that you own a computer with a modem and have a telephone. You can get the software you need to use Juno from someone else who uses the service, from Juno's website or by phone, from Juno direct, they'll mail you a copy of the software via snail mail (that's what email users call the US Post Office). Once you have the software, install it on your computer. The program sets itself up, and all you do is click on "check mail" and the system dials up Juno's service and downloads your mail. Same with sending. After you have written an email, click on send, and your computer dials into the local number and off goes your email. Your phone is only tied up for the brief time it takes to log on and process your mail, usually just a minute or two. This is too good to be true, you ask! Well, you will have to put up with the ads (that's how it's paid for, it's advertiser supported) and you cannot attach files which means that if you want to see the latest picture of your new baby granddaughter, you'll have to wait for the snail mail.
Internet based This is the "free" email that you see plastered all across the Internet. Microsoft offers it (theirs is called Hotmail). Most of the Internet search engines offer free email accounts (like Yahoo!). Netscape also offers free email. So what's the benefit, if I already have an email account? Built in virus protection, for one.
Other than that, depends on how you use your email. If you only check your email occasionally, and almost always need to check it from just one location like home or work, this is probably not for you. If, however you live in a home with lots of other email users (like my wife and two kids), this is a way that everyone can have their own email address. If you have a need to check your email from somewhere else, this is a great tool. With Internet based email, you can check your email from any computer, anywhere and at anytime, without having to go through a change in the computer's setup. It is yours, free, for life. You'll never need to notify all your emailers that you've changed your email address (again). You can even check your mail at the public library. You simply go to your email service's home page, login and there's your mail. Ready to be read, replied to or forwarded. Attachments -- yes! Most allow you to attach files and graphics (like photos of grandkids). Sounds like a hassle -- Will I need to check each and everyone of these different accounts? This can be handled in a couple of different ways, depending on how you use your email. If you have multiple accounts and you check your email from the same place all the time, say from home or from the office, then configuring you computer's email program is the way to go. Microsoft's Outlook Express will check multiple accounts and v5 specifically support's Microsoft's Internet based email, Hotmail. Many Internet based email services now offer a way to check your other email accounts via their website. What does this mean? It means that you visit your brother-in-law in upstate New York. You ask if you can check your email? Your skeptical in-law watches in amazement as you not only check your home email, you also check your office email and your Internet email, print out what you need and are off his computer in just a couple minutes. He now thinks you are an Internet guru.
If you do not wish to go through the hassle of setting up either your own terminal for multiple accounts or an Internet based account, then maybe a Forwarding account is the way to go. You get a permanent Internet based email address, Bigfoot offers a free, lifetime service where your bigfoot email address automatically forwards your email to any up to five different accounts you specify. This means that your mail will be delivered to any other email address you want. You can have it go to your home email account, plus your office account and even to your brother-in-law's in upstate New York all at the same time, automatically. And you can change it at any time, from any computer that has access to the Internet.

Origins of the Internet
The first recorded description of the social interactions that could be enabled through networking was a series of memos written by J.C.R. Licklider of MIT in August 1962 discussing his "Galactic Network" concept. He envisioned a globally interconnected set of computers through which everyone could quickly access data and programs from any site. In spirit, the concept was very much like the Internet of today. Licklider was the first head of the computer research program at DARPA, 4 starting in October 1962. While at DARPA he convinced his successors at DARPA, Ivan Sutherland, Bob Taylor, and MIT researcher Lawrence G. Roberts, of the importance of this networking concept.Leonard Kleinrock at MIT published the first paper on packet switching theory in July 1961 and the first book on the subject in 1964. Kleinrock convinced Roberts of the theoretical feasibility of communications using packets rather than circuits, which was a major step along the path towards computer networking. The other key step was to make the computers talk together. To explore this, in 1965 working with Thomas Merrill, Roberts connected the TX-2 computer in Mass. to the Q-32 in California with a low speed dial-up telephone line creating the first (however small) wide-area computer network ever built. The result of this experiment was the realization that the time-shared computers could work well together, running programs and retrieving data as necessary on the remote machine, but that the circuit switched telephone system was totally inadequate for the job. Kleinrock's conviction of the need for packet switching was confirmed.
In late 1966 Roberts went to DARPA to develop the computer network concept and quickly put together his plan for the "ARPANET", publishing it in 1967. At the conference where he presented the paper, there was also a paper on a packet network concept from the UK by Donald Davies and Roger Scantlebury of NPL. Scantlebury told Roberts about the NPL work as well as that of Paul Baran and others at RAND. The RAND group had written a paper on packet switching networks for secure voice in the military in 1964. It happened that the work at MIT (1961-1967), at RAND (1962-1965), and at NPL (1964-1967) had all proceeded in parallel without any of the researchers knowing about the other work. The word "packet" was adopted from the work at NPL and the proposed line speed to be used in the ARPANET design was upgraded from 2.4 kbps to 50 kbps. 5
In August 1968, after Roberts and the DARPA funded community had refined the overall structure and specifications for the ARPANET, an RFQ was released by DARPA for the development of one of the key components, the packet switches called Interface Message Processors (IMP's). The RFQ was won in December 1968 by a group headed by Frank Heart at Bolt Beranek and Newman (BBN). As the BBN team worked on the IMP's with Bob Kahn playing a major role in the overall ARPANET architectural design, the network topology and economics were designed and optimized by Roberts working with Howard Frank and his team at Network Analysis Corporation, and the network measurement system was prepared by Kleinrock's team at UCLA. 6
Due to Kleinrock's early development of packet switching theory and his focus on analysis, design and measurement, his Network Measurement Center at UCLA was selected to be the first node on the ARPANET. All this came together in September 1969 when BBN installed the first IMP at UCLA and the first host computer was connected. Doug Engelbart's project on "Augmentation of Human Intellect" (which included NLS, an early hypertext system) at Stanford Research Institute (SRI) provided a second node. SRI supported the Network Information Center, led by Elizabeth (Jake) Feinler and including functions such as maintaining tables of host name to address mapping as well as a directory of the RFC's. One month later, when SRI was connected to the ARPANET, the first host-to-host message was sent from Kleinrock's laboratory to SRI. Two more nodes were added at UC Santa Barbara and University of Utah. These last two nodes incorporated application visualization projects, with Glen Culler and Burton Fried at UCSB investigating methods for display of mathematical functions using storage displays to deal with the problem of refresh over the net, and Robert Taylor and Ivan Sutherland at Utah investigating methods of 3-D representations over the net. Thus, by the end of 1969, four host computers were connected together into the initial ARPANET, and the budding Internet was off the ground. Even at this early stage, it should be noted that the networking research incorporated both work on the underlying network and work on how to utilize the network. This tradition continues to this day.
Computers were added quickly to the ARPANET during the following years, and work proceeded on completing a functionally complete Host-to-Host protocol and other network software. In December 1970 the Network Working Group (NWG) working under S. Crocker finished the initial ARPANET Host-to-Host protocol, called the Network Control Protocol (NCP). As the ARPANET sites completed implementing NCP during the period 1971-1972, the network users finally could begin to develop applications.
In October 1972 Kahn organized a large, very successful demonstration of the ARPANET at the International Computer Communication Conference (ICCC). This was the first public demonstration of this new network technology to the public. It was also in 1972 that the initial "hot" application, electronic mail, was introduced. In March Ray Tomlinson at BBN wrote the basic email message send and read software, motivated by the need of the ARPANET developers for an easy coordination mechanism. In July, Roberts expanded its utility by writing the first email utility program to list, selectively read, file, forward, and respond to messages. From there email took off as the largest network application for over a decade. This was a harbinger of the kind of activity we see on the World Wide Web today, namely, the enormous growth of all kinds of "people-to-people" traffic.
