INTERNET :History of Internet and Types of Internet.
The internet |
Welcome to techassam. Today you will know all about the internet.
If you'r reading this article, it's likely that you spend a fair amount of time online.
Today, we are going to tell on such a topic which is available in everywhere, in world,in your area, in your life.
Without this you can't do anything , any work, without this our life is incompleted, without this you can't see this article too you understand that which topic we will tell you today, the internet.
Internet:- Internet is a huge network of computers which links Many different types of computer to each other.
INTERNET stands for Interconnected Network That is a network System That connects millions of web servers. with the help of Internet ,The entire world is Connected.
The internet is global network of billions computer and other electronics devices.With internet it's possible to access almost any information, communication with each other. In Today's world life can't be imagined without internet. internet has made our life easier and quicker.
internet includes Several high bandwidth data likes that comprise the internet"backbone".These likes are connected to major internet hubs that distribite data to other locations, such as web servers and ISP.
History of Computer :-
The first computer networks were dedicated special-purpose systems such as SABRE (an airline reservation system) and AUTODIN I (a defense command-and-control system), both designed and implemented in the late 1950s and early 1960s. By the early 1960s computer manufacturers had begun to use semiconductor technology in commercial products, and both conventional batch-processing and time-sharing systems were in place in many large, technologically advanced companies. Time-sharing systems allowed a computer’s resources to be shared in rapid succession with multiple users, cycling through the queue of users so quickly that the computer appeared dedicated to each user’s tasks despite the existence of many others accessing the system “simultaneously.” This led to the notion of sharing computer resources (called host computers or simply hosts) over an entire network. Host-to-host interactions were envisioned, along with access to specialized resources (such as supercomputers and mass storage systems) and interactive access by remote users to the computational powers of time-sharing systems located elsewhere. These ideas were first realized in ARPANET, which established the first host-to-host network connection on October 29, 1969. It was created by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense.
ARPANET was one of the first general-purpose computer networks. It connected time-sharing computers at government-supported research sites, principally universities in the United States, and it soon became a critical piece of infrastructure for the computer science research community in the United States. Tools and applications—such as the simple mail transfer protocol (SMTP, commonly referred to as e-mail), for sending short messages, and the file transfer protocol (FTP), for longer transmissions—quickly emerged.
In order to achieve cost-effective interactive communications between computers, which typically communicate in short bursts of data, ARPANET employed the new technology of packet switching. Packet switching takes large messages (or chunks of computer data) and breaks them into smaller, manageable pieces (known as packets) that can travel independently over any available circuit to the target destination, where the pieces are reassembled. Thus, unlike traditional voice communications, packet switching does not require a single dedicated circuit between each pair of users.
Wireless internet :-
Wireless broadband connects a home or business to the Internet using a radio link between a small receiver on your home or business.
Wireless technologies using longer-range directional equipment provide broadband service in remote or sparsely populated areas where DSL or cable modem service would be slow, unavailable, or costly to provide.
This is fantastic simple technology, and is something that Solway Comms specialises in. We have a network of masts in north and west Cumbria that transmit this wireless internet to a receiver on your property.
Download and upload speeds are upto 20mb/s.
DIA (Direct Internet Access) :-
Dedicated Internet Access means that the specified amount of bandwidth sold has been carved out and dedicated for your use.
You won’t be sharing with anyone else, but will be connected directly to the internet superhighway. Other means of connecting to the internet are impacted by how many other people on your street are using the internet, but for DIA customers this isn’t an issue.
Solway Comms can provide a wireless DIA connection. This is a fantastic solution for businesses because it means you get a strong reliable dedicated connection, without having to dig up the street (expensive!) to lay a new cable.
Fibre to the premises :-
In Fibre to the premises, fast-fibre optic cables run directly to homes and offices, providing a more stable, efficient and reliable connection than the hybrid copper and fibre systems.
They can also support broadband speeds of up to 1Gbps, enough to download an HD TV programme in five seconds.
Fibre optic technology converts electrical signals carrying data to light and sends the light through transparent glass fibres about the diameter of a human hair.
Fibre transmits data at speeds far exceeding current DSL or cable modem speeds, typically by tens or even hundreds of Mbps. Especially when you have a FTTP (Fibre to the premises) connection, which isn’t shared with anyone else.
Solway Comms is able to install fibre optic internet to your business.
It can be a more expensive option.
We don’t provide the following services however we can advise on them…
DSL (Digital Subscriber Line)
DSL is a wired connection that transmits data faster over traditional copper telephone lines already installed to homes and businesses.
DSL-based broadband provides transmission speeds ranging from several hundred Kbps to millions of bits per second (Mbps).
The availability and speed of your DSL service may depend on the distance from your home or business to the closest telephone company facility.
In Cumbria, the infrastructure to provide people with a DSL connection isn’t always in place, meaning an alternative such as wireless internet is a good choice.
Satellite :-
Satellite
Just as satellites orbiting the earth provide necessary links for telephone and television service, they can also provide links for broadband.
Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased, the consumer’s line of sight to the orbiting satellite, and the weather. Typically a consumer can expect to receive download speeds of about 500 Kbps and uploads at a speed of about 80 Kbps.
One of the main downsides associated with satellite Internet is slow speeds. The has to reach the satellite almost 22,000 miles away and return back to earth with the requested data, which can make it slow.
Dial up:-
Remember dial up internet? This analog signal is converted to digital via the modem and sent over a land-line serviced by a public telephone network.
Telephone lines are variable in quality and the connection can be poor at times.
The lines regularly experience interference and this affects the speed, anywhere from 28K to 56K.
Since a computer or other device shares the same line as the telephone, they can’t be active at the same time.
Mobile internet (4G and 5G):-
Mobile technology provides wireless Internet access through mobile phones.
The speeds vary depending on the provider, but the most common are 4G and now 5G. 3G is becoming increasingly obsolete.
A 3G is a term that describes a 3rd generation mobile network obtaining mobile speeds of around 2.0 Mbps.
4G is the fourth generation of mobile internet and is much faster than this, but not always available in areas of Cumbria.
5G is being rolled out in what providers call the places ‘that matter most’ – which doesn’t include Cumbria currently.
