What is Internet
Internet is the way to connect online with others in world. Internet is a global wide area network that connects computer systems across the world. In other simple world it is the computer network. It allows computer users to connect with computers all over the world, and which carries email. The origin of internet is 1960. In present it is a part of studies. DARPA developed internet in US. The internet boost the experience of playing games buy online pay them. Internet also provide way to search job online. Internet is like bone arrow of Blogs. In common use and the media, it is often erroneously not capitalized, viz. the internet.
The second biggest use of the Internet is to send and receive e-mail. E-mail is private and goes from one user to another. Internet makes communication easy and communication can be dangerous too. It’s responsible for online scams. If the site contain https:// that mean it’s secure. Like our own blog https://amazingshining.com it’s secure to visit for you. Some websites may trick people into downloading viruses.
Some emails can also have harmful files with them as “attachments”. In internet chatrooms, people might be preying on others or trying to stalk or abuse them. The Internet contains content that many people find offensive such as pornography, as well as content intended to be offensive.
Some peoples confuse between Internet & Intranet. So here we are know guiding few things about Intranet.
What is Intranet
It is a private network accessible only to an organization’s staff. Intranets began to appear in a range of larger organizations from 1994. Certain aspects are non-static.
What is Computer Network
It is very well known as Data Network. Computer network is DTN which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. From 1973 to 1974, Cerf’s networking research group at Stanford worked out details of the idea, resulting in the first TCP specification. Some of the early TCP/IP stacks were written single-handedly by a few programmers. Jay Elinsky and Oleg Vishnepolsky of IBM Research wrote TCP/IP stacks for VM/CMS and OS/2, respectively. In 1984 Donald Gillies at MIT wrote a ntcp multi-connection TCP. Phil Karn created KA9Q TCP starting in 1985.
It is the principal communications protocol in the IPS. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974.
During the design phase of the ARPANET and the early Internet, the security aspects and needs of a public. The IETF has been pursuing further studies.
What is ARPANET
ARPANET is known as Advanced Research Projects Agency Network. It
was an early packet-switching network and the first network to implement the protocol suite TCP/IP. Both technologies became the technical foundation of the Internet. ARPANET packet switching was based on concepts and designs by Leonard Kleinrock, Paul Baran, Donald Davies, and Lawrence Roberts.
What is Coaxial Cable
Coaxial cable is a type of transmission line. Some of them have jackets.
The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. They used as transmission line for radio frequency signals.
Normally, the shield is kept at ground potential and a signal carrying voltage is applied to the center conductor. They use braided copper wire forming the shield.
What is Node
Node is either a redistribution point or a communication endpoint.
The definition of a node depends on the network and protocol layer referred to.
A passive distribution point such as a distribution frame or patch panel is consequently not a node. If the network in question is a distributed system, the nodes are clients, servers or peers. A peer may sometimes serve as client, sometimes server.
Internet Service Provider
ISP provides internet services to us. They may be organized in various forms.
Such as commercial, or otherwise privately owned. The internet was developed as a network. ISP provides email, & other services. Free ISPs are Internet service providers that provide service free of charge.
What is Email
Electronic Mail is a way to send message in just few seconds to others. It
is the most common form used online. Computer-based mail and messaging became possible with the advent of time-sharing computers in the early 1960s.
Over time, a complex web of gateways and routing systems linked many of them.
The diagram to the right shows a typical sequence of events that takes place when sender Alice transmits a message using a mail user agent (MUA) addressed to the email address of the recipient. Each message has exactly one header, which is structured into fields. Each field has a name and a value.
Informally, each line of text in the header that begins with a non-whitespace printable character begins a separate field. The field name starts in the first character of the line and ends before the separator character. Email header fields can be multi-line. Each line recommended to be no more than 78 characters. Although the technical limit is 998 characters. Most email software is 8-bit clean but must assume it will communicate with 7-bit servers and mail readers.
Most modern graphic email clients allow the use of either plain text or HTML for the message body at the option of the user. HTML email messages often include an automatically generated plain text copy as well, for compatibility reasons.
Messages are exchanged between hosts using the Simple Mail Transfer Protocol.
