Internet

The TCP/IP suite of protocols is the set of protocols used to communicate across the internet. It is also widely used on many organizational networks due to its flexibility and wide array of functionality provided. TCP/IP is a set of protocols which is used to govern the web. The division of TCP/IP protocols layer wise and function wise is as follows: * SLIP - Serial Line Internet Protocol. This protocol places data packets into data frames in preparation for transport across network hardware media. This protocol is used for sending data across serial lines. There is no error correction, addressing or packet identification. There is no authentication or negotiation capabilities with SLIP. SLIP will only support transport of IP packets. * CSLIP - Compressed SLIP is essentially data compression of the SLIP protocol. It uses Van Jacobson compression to drastically reduce the overhead of packet overhead. This may also be used with PPP and called CPPP. * PPP - Point to Point Protocol is a form of serial line data encapsulation that is an improvement over SLIP which provides serial bi-directional communication. It is much like SLIP but can support AppleTalk, IPX, TCP/IP, and NetBEUI along with TCP/IP which is supported by SLIP. It can negociate connection parameters such as speed along with the ability to support PAP and CHAP user authentication. * Ethernet - Ethernet is not really called a protocol. There are also many types of ethernet. The most common ethernet which is used to control the handling of data at the lowest layer of the network model is 802.3 ethernet. 802.3 ethernet privides a means of encapsulating data frames to be sent between computers. It specifies how network data collisions are handled along with hardware addressing of network cards. * ARP - Address Resolution Protocol enables the packaging of IP data into ethernet packages. It is the system and messaging protocol that is used to find the ethernet (hardware) address from a specific IP number. Without this protocol, the ethernet package could not be generated from the IP package, because the ethernet address could not be determined. * IP - Internet Protocol. Except for ARP and RARP all protocols' data packets will be packaged into an IP data packet. IP provides the mechanism to use software to address and manage data packets being sent to computers. * RARP - Reverse address resolution protocol is used to allow a computer without a local permanent data storage media to determine its IP address from its ethernet address. * TCP - A reliable connection oriented protocol used to control the management of application level services between computers. It is used for transport by some applications. * UDP - An unreliable connection less protocol used to control the management of application level services between computers. It is used for transport by some applications which must provide their own reliability. * ICMP - Internet control message protocol (ICMP) provides management and error reporting to help manage the process of sending data between computers. (Management). This protocol is used to report connection status back to computers that are trying to connect other computers. For example, it may report that a destination host is not reachable. * FTP - File Transfer Protocol allows file transfer between two computers with login required. * TFTP - Trivial File Transfer Protocol allows file transfer between two computers with no login required. It is limited, and is intended for diskless stations. * NFS- Network File System is a protocol that allows UNIX and Linux systems remotely mount each other's file systems. * SNMP - Simple Network Management Protocol is used to manage all types of network elements based on various data sent and received. * SMTP - Simple Mail Transfer Protocol is used to transport mail. Simple Mail Transport Protocol is used on the internet, it is not a transport layer protocol but is an application layer protocol. * HTTP - Hypertext Transfer Protocol is used to transport HTML pages from web servers to web browsers. The protocol used to communicate between web servers and web browser software clients. * BOOTP - Bootstrap protocol is used to assign an IP address to diskless computers and tell it what server and file to load which will provide it with an operating system. * DHCP - Dynamic host configuration protocol is a method of assigning and controlling the IP addresses of computers on a given network. It is a server based service that automatically assigns IP numbers when a computer boots. This way the IP address of a computer does not need to be assigned manually. This makes changing networks easier to manage. DHCP can perform all the functions of BOOTP. * BGP - Border Gateway Protocol. When two systems are using BGP, they establish a TCP connection, then send each other their BGP routing tables. BGP uses distance vectoring. It detects failures by sending periodic keep alive messages to its neighbors every 30 seconds. It exchanges information about reachable networks with other BGP systems including the full path of systems that are between them. Described by RFC 1267, 1268, and 1497. * EGP - Exterior Gateway Protocol is used between routers of different systems. * IGP - Interior Gateway Protocol. The name used to describe the fact that each system on the internet can choose its own routing protocol. RIP and OSPF are interior gateway protocols. * RIP - Routing Information Protocol is used to dynamically update router tables on WANs or the internet. A distance-vector algorithm is used to calculate the best route for a packet. RFC 1058, 1388 (RIP2). * OSPF - Open Shortest Path First dynamic routing protocol. A link state protocol rather than a distance vector protocol. It tests the status of its link to each of its neighbors and sends the acquired information to them. * POP3- Post Office Protocol version 3 is used by clients to access an internet mail server to get mail. It is not a transport layer protocol. * IMAP4 - Internet Mail Access Protocol version 4 is the replacement for POP3. * Telnet is used to remotely open a session on another computer. It relies on TCP for transport and is defined by RFC854. * BAP - Bandwidth Allocation Protocol is a bandwidth control protocol for PPP connections. It works with BACP. * BACP - Bandwidth Allocation Control Protocol. * IP - Internet Protocol. Except for ARP and RARP all protocols' data packets will be packaged into an IP data packet. IP provides the mechanism to use software to address and manage data packets being sent to computers. * SLIP - Serial Line Internet Protocol. This protocol places data packets into data frames in preparation for transport across network hardware media. This protocol is used for sending data across serial lines.

You must have an ISP (Internet Service Provider) - after that in your local network, you must have the FF. devices Modem, which is basically connected to your phone line, then a straight-through cable (RG45) that connect from your modem to your PC, and if you need a wireless network, you can have a wireless router to distribute your Internet connection to your place.

Hope this will help ^_^

Computers are wonderfully efficient when they are working properly, but they are very complicated and have endlessly many different ways of breaking down, and when they do break down they are often very difficult to fix. Compare record keeping with a computer or with a pen and a piece of paper. The computer records can be much more easily updated and edited than paper records can be, but the paper will never crash, even if there is a power failure.

The first private Internet service providers (ISPs) began to emerge in the late 1980s and early 1990s. However, it was not until 1991 that a series of agreements made it possible for traffic from private ISPs to traverse the full breadth of the Internet "backbone," which was then maintained by the National Science Foundation (NSF), with government funds and therefore subject to a fairly rigorous acceptable use policy that generally forbade all but educational and research uses. E-commerce took hold in a limited way from 1991 onward but 1995 is when the Internet really took off as a fully private and commercial venture--this was the year that the NSF withdrew its support from the Internet backbone, turning it over to private control and therefore universally lifting anti-commercial acceptable use policies; that Internet registrar Network Solutions was allowed to charge for registering domain names; and that credit card encryption made large-scale e-commerce both practical and appealing to consumers. Add in the introduction of Netscape, which was, after Mosaic, the second widely available web browser with a graphical user interface (GUI) in 1994 (and a smash hit), and you had all the ingredients in place for the .com boom that occupied the rest of the 1990s. So the answer to your question is: it started in the late 1980s in a limited way, picked up steam in the early 1990s, and was fully realized in 1995--though saying that the Internet became "a commercial product" is not really an accurate way of putting it; the Internet does not properly refer to a product of any sort but rather the infrastructure and protocols (largely TCP/IP) that make seamless interconnection of multiple networks possible.

It might refer to high speed internet but for todays applications that is really slow. You would not be able to stream, download or do a lot of stuff with that kind of speed. There is a reason they use Mbps for speed nowadays. Look into IVC Telecom for high speed internet plans in Canada.

The development of what we now call the Internet started in 1957 when the Soviet Union launched Sputnik 1, the first satellite, beating the United States into space. The powers behind the American military at the time became highly alarmed as this meant that the USSR could theoretically launch bombs into space, and then drop them anywhere on earth. In 1958 the concerns of people in the US military triggered the creation of the Defence Advanced Research Projects Agency Network (DARPANET).
In 1962 MIT students were working on the origins of graphical programs and JR Licklieder writes about his idea of a "intergalactic network." Kleinrock does a dissertation on communication networks. In 1963 Licklieder contracts with MIT, UCLA, and BBN to work on his "network." Syncom the first communications satellite is launched. MIT works on secure packet switching networks in 1964 and IBM 360 computer goes on the market. In 1965 MIT connects computers on telephone line. The modem is invented in 1967 and in 1970 file transfer is developed. In 1973 30 institutions connect on networks. In 1974 Ethernet is invented. Apple II begins sales in 1977 and in 1978 small computers with modems go on sale. In 1981 200 computers connect and in 1982 first coaxial cable interface is made. Macs go on sale in 1984 and by 1985 2,000 computers are connected. By 1987 there is now 10,000 computers connected, and 1988 sees 80,000 computers connected. In 1990 there are 300,000 and in 1991 10 billion packets per month with 600,000 computers in 100 countries are connected. As it can be seen the Internet is not new.

I would say that some sources found over the internet are reliable while others are not. This is often because in many websites, people get to post whatever it is that they want without someone checking to see if the information presented is correct. However, this depends on the type of website that you are referring to. All in all, however, books are ALWAYS reliable because the information in them are always checked for 100% accuracy.

A torrent is a file sharing techniqie that allows some one computer to download a file from many computers at one time allowing for much faster downloads of large files such as movies.

Comast is a popular telecommunications company offering cable television, phone, and internet service. If a person wants to check for Comcast internet availability in their area, they only need to visit the Comcast website or call Comcast. Internet availability is based upon state of residence and zip code.

You can always try a reverse google image search. What you need to do is go to google images then drag and drop the image you are inquiring about in the search bar and provide any terms or words that help aid in the search. Google will then trace that image and see if it has any matches.

No, DSL uses the same telephone line you use to make calls.

A website address is also referred as a URL, or Uniform Resource Locator. It can also be called a site.

You can be hacked by giving out personal information, responding to spam emails or even visiting the wrong website. It is best to have the latest firewalls and security software to ensure that you do not get hacked.

It Depends, Go to ---- keepvid.com and there you go. :)

A URL is a lot easier to remember than an IP address. Trying to recall sets of numbers from memory can be difficult. Also, a URL will remain the same. Some ISPs use dynamic IP, which means that it will change periodically. So you would never get to remember the addresses for all of your favourite sites!

A URL can also link to a particular page within a server. Most servers don't have the website on the root of the Hard Drive, similar to saving things to My Documents rather than C:.

I recommend this site, which is used by most major companies 

In this Semrush review, I’m going to put one of the best-known SEO tools available to the test.  I’m going to discuss how it stacks up in terms of:  •Domain analysis •Keyword research features •Rank tracking •Backlink analysis •Link building tools •Site auditing •Ease of use •Pricing and value for money •Support …and more!  Let’s start with an important question… 

What is Semrush? Simply put, Semrush is a product that helps you optimize your website for search engines.  Created in 2008 by Oleg Shchegolev and Dmitry Melnikov, it now has a very large user base — over 7 million users, according to the company — and is one of the most popular SEO tools currently available.  Semrush works by giving you a lot of information, which you can use to either:  create new web content that is likely to attract traffic identify link-building opportunities tweak technical aspects of your site content so that it achieves a higher search ranking. For example, Semrush can give you keyword suggestions (based on phrases you enter) that can be used as the basis for writing blog posts that are likely to perform well in search results.  It can also tell you how difficult it will be to rank for specific search phrases.  It will suggest websites that might be worth approaching for backlinks.  And it allows you to perform an “SEO audit” on your website to find out if there are any technical improvements you can make to it that will help you achieve better search results.  That’s just the beginning though — there are many other features provided by Semrush that are designed to help you improve your site’s position in search results.  I’ll go through these in depth below, highlighting all their pros and cons.  So let’s dive in! I’ll kick things off by looking at something called domain analysis.

Controlling internet access comes in handy in areas like schools, libraries and even your home. Parents, teachers and librarians try to make sure children aren't visiting certain adult sites while on the computer.

TCP/IP is composed of layers, wherein each layer is responsible for performing certain operations on the data it receives and passing it to the higher layers. Each layer deals with certain issues related to the transmission of data and renders certain services to its higher layers.

The TCP/IP model consists of the link layer, the Internet layer, the transport layer and the application layer. Each layer consists of a set of protocols that function on the level of that layer. The link layer protocols are responsible for connecting the nodes in a network. The Internet layer consists of protocols, specifications and methods that are used to transport data packets across the network. The transport layer protocols deal with the transmission of data packets between source and destination network hosts. The application layer, the topmost layer in TCP/IP, directly interacts with application services. Thus, we see that TCP/IP functions at all the levels of communication between the components of a network. It is truly, the heart of network communication.

This is the same as asking it Television is a good thing. It really depends on who you are and what you are expecting to get from it. TV can be seen as a bod thing if you become too dependant on it for your daily life and your daily learning. The TV has been viewed as a "goggle box" that leads to the destruction of the viewers mind, it has also been seen as an educational tool. If we think about TV a little bit we can see that watching so called "pulp" TV shows (with little educational value) too often (or always) could be a bad thing, but then if we think about TV as being educational we can see that most schools and teachers show it to kids to educate them (ie: National Geographic, PBS etc.) The same goes for the Internet (pls note: capital I not lowercase because in this case it is a proper noun). So the answer comes down to what you watch on the net and not the net itself. It's a bit like the gun debate: (ie: guns don't kill people, people kill people). So regards the Internet, it's not the net that is the problem, it is the content on the net that can be the problem.

"Are landline phones passe? Not really! There are still many people who would prefer a landline phone to a cell or satellite phone. I imagine that with the passing years, landlines will be phased out but I can't see that happening too soon."

URL, Uniform Resource Locater.

Your computer does not have a url, only web servers have this service, all it does is point your web browser to the right hosting server.

If you were refering to your IP address, this could have many answers depending on your situation.
