What is the acronym for ISP? It stands for “internet service provider,” which is an acronym for a business or organization that charges businesses and consumers for access to the internet. ISP services allow users to browse the internet and do online tasks like emailing, shopping, and working from home.
An information service provider, a storage service provider, an internet service provider, or any combination of the three may also be included in the industry’s definition of an ISP.
The types of internet service providers can be commercial, community-owned, non-profit, and private. Examples of ISPs include Virgin Media, EE, BT and AOL. Some ISPs may also provide other services such as web hosting, domain registration, email and browser services.
There are different tiers of ISP, ranging from local providers to tier one companies owned by infrastructure providers (fibre-optic cables, telecom networks). A local ISP would buy access from a larger ISP to sell to customers.
The internet was initially only used for official government purposes. Computers functioned as a kind of phone line before the advent of commercial ISPs; they called one another to create a connection through a procedure called a handshake. The introduction of the internet gradually limited the number of individuals who could access it from a number of public access points to private schools and universities. To enable more people to join online, The World, the first commercial ISP, was established in 1985. The number of internet service providers increased during the 1990s as more people wanted to have an online presence.
How crucial is an Internet service provider for communication and computer operations? The manner in which ISPs connect over a wide area suggests that they act as a communications highway. Backbones, or major communication routes made possible by satellites and other media, are used to construct connections. The term “media” describes the actual physical connections—such as cables or lines—that a residence makes to the internet. For a charge determined by the provider, ISPs can connect towns, nations, and even continents.
History of ISP
The internet was developed as a network between government research laboratories and participating universities to communicate in the 1950s. By the late 1980s, there was increased internet use in the form of email using dial-up connections through a phone line. Full access to the internet was not readily available.
ISPs such as CompuServe and American Online (AOL) were the first commercial internet service providers in the US to provide limited access to the internet by email. Boston, US-headquartered The World was the first commercial ISP to provide an internet network service to the world.
Despite the growing popularity of email and rising internet activities, the internet remained largely inaccessible in the late 1980s as users required technical knowledge to dial into the system. Additionally, there was no agreement on how documents on the network were formatted.
British computer scientist Tim Berners-Lee developed the World Wide Web, a way of structuring and linking all the information on the internet, making it quick and easy to access data. Following that development, the internet and the World Wide Web became an established phenomenon by the mid-1990s.
The internet is often confused with the World Wide Web. The internet is a network infrastructure that connects devices together. The world wide web is a way of accessing information through the internet medium.
Internet connectivity options and speed continued to improve in the 2000s as ISP developed broadband technology, a higher bandwidth connection to the internet compared with the standard phone line.
Some of the top ISP providers in the US are:
- AT&T: AT&T is one of the biggest ISPs in the US, offering high-speed internet services to millions of customers in many states. It offers Digital Subscriber Line (DSL) broadband, fixed, and fiber wireless internet service.
- Verizon: Verizon is among the first ISPs that offered fiber optic internet services. Its presence is in various US states serving over 30 million customers. It also offers DSL services with fast internet speeds.
- Xfinity: Xfinity offers internet, cable TV, wireless, and telephone services. About 50+ million people living in around 40 states use Xfinity for their businesses and homes. It provides extraordinary fast internet service ranging from 20 Mbps to hundreds.
- Spectrum Internet: Introduced quite recently in 2014, this ISP serves 25+ million consumers from around 41 states. It offers a variety of fiber and broadband services both for commercial and residential purposes.
- CenturyLink: Around 52 million people from 36 states use CenturyLink for its internet services like DSL, fiber-based internet, etc. It also offers bundled services with DIRECTV so that you can avail of the complete package.
Other providers in the US are Frontier, Cox, Sparklight, Mediacom, Windstream, Earthlink, and more.
Types of ISPs
Back in the 90s, ISPs were one of three types: dial-up services, DSL by phone providers, and broadband by cable companies. Over the following two decades, though, dial-ups grew rarer, owing to low speed, while other options flourished.
Let’s look at the different types of ISPs available today.
Dial-Up Internet Providers
Dial-up internet uses your current phone line to connect you to the internet. To establish connectivity, it requires you to dial an access number (similar to a phone number) with a modem. When you are online, you can’t make a phone call with your number, unlike with a DSL connection.
Dial-up is easily accessible via landline, and it’s secure and cost-efficient. However, it’s very slow — 56 kbps is the maximum internet speed you can attain with it. Given the advanced technologies we use today, this speed is not sufficient for most operations, especially as some web pages or apps will show trouble loading and may time out before they load.

This is why people are shifting to other options. According to a 2021 Statista report, only 1.9% of households used dial-ups in the US. It’s used in some rural areas with no broadband availability, but it’s been otherwise abandoned.
Digital Subscriber Line (DSL) enables internet connection through a telephone line. The services are widely available because houses are wired for phone connections already. It’s provided by traditional phone companies.
The DSL technology leverages extra signals that telephone signals don’t use. It utilizes a DSL router to connect to a telephone jack through a phone cable. These capabilities enable the users to use the internet even when using their telephones or the telephone is ringing.
DSL is not shared among the users and can be the best option if you don’t have other options accessible at your place. It offers average internet speed and does not require you to invest in expensive equipment. Just buy a modem, and your telephone connection will enable you to connect to the internet. So, when you buy a DSL connection, make sure you are close enough to the service provider because the speed affects distance.
According to another Statista report published last year, around 57% of US consumers use broadband such as DSL and cable, making it the most popular option.
Broadband Cable Providers
Cable TV companies generally offer broadband cable services. Broadband cables use coaxial cables, which deliver cable TV to homes. The service providers also offer internet services that are reliable and fast to help you perform a variety of operations at home or office. You may achieve internet speeds from one to a hundred Mbps.
The benefit of using broadband cables is they involve low latencies, which doesn’t affect you much. You may experience fewer lag times while performing certain actions like opening a website, watching a video, or playing an online video game.
Due to their wide availability, broadband cables are popular among internet users. You can also refer to the above statistic, where more than 50% of consumers use it to connect to the internet. However, these services also depend upon your geographic location. It’s shared by different users in your neighborhood, and the bandwidth allotted is distributed between everyone. So, the fewer users or traffic coming from them, the faster the internet connection will be.
Using a broadband cable gives you the option to save some money by allowing you to bundle your services, like the internet and cable TV.
The internet connection leveraging the technology of fiber optics is the fastest internet service. The ISPs offering this service use fiber-optic cables created from glass strands for data transmission at the speed of light. It does not use copper. The reasons for using fiber are numerous — it’s a medium to transmit light and results in qualities like:
- Immunity from electromagnetic interference
- High bandwidth capability like gigabytes per second
- Higher transmission signals of a maximum of 150 miles
- Consistency and reliability
Fiber offers the maximum speed and lowest latencies while using the internet. You can expect to experience few delays while playing games online, doing video conferencing, streaming videos, and so on. Fiber connection is built to support heavy internet usage, with maximum bandwidth and support to allow users to stream videos simultaneously, share large files, and use IoT devices at home or office.
At present, new advancements are being made, such as establishing connections between countries via fiber optics running along the ocean bed for incredible speeds without interference. However, this type of connectivity is expensive, so there are fewer areas and establishments where fiber-optics connectivity is enabled.
In addition, many areas are still not wired to help this technology reach consumers. Since it’s a relatively new concept, efforts are made to increase its availability through satellite dishes.
A popular example of fiber-optics connectivity is Google Fiber, offering a full gigabyte of bandwidth at a similar price as many DSL and cable providers. A 2021 report says that fiber usage has exceeded 30% of broadband subscriptions in many countries.
Satellite Internet Providers
Satellite internet service providers utilize geostationary satellites for data transmission between the internet and users.
Since data travels from space to earth — a distance of 22,000 miles — these high distances may cause considerable delays. In fact, satellite internet offers the highest response delays among all the other types of connectivity. In addition, speed can be severely impacted by weather conditions. Speed is also dependent upon network congestion, or how busy a network is at a particular time.
Another drawback with satellite is that you can constantly be disturbed by limited bandwidth. It won’t be sufficiently reliable if you want consistent connectivity to conduct your business process or play online games.
However, it’s the only hope for many people in rural areas, deserts, mountainous places, and farms who want relatively high speeds. It’s a better option than mobile internet and dial-ups. Although it’s not that fast compared to other types of connectivity, the benefit is that it poses fewer environmental impacts and offers greater location flexibility. (It’s also a great option for recovery centers after a natural calamity.)
Another type of ISP provider is the one that offers Wi-Fi connections. Multiple users can access Wi-Fi connectivity with ease and flexibility like nowhere else because a modem isn’t required. Using Wi-Fi gives you the option to move around while staying connected. Nowadays, you can get Wi-Fi connections using a small pocket device that you can carry anywhere and work with much independence.
Moreover, Wi-Fi is also offered by governments, hotels, restaurants, and train stations freely in various parts of the world. This allows internet access to larger masses and helps people who can’t afford internet plans.
Access providers offer internet access by using various technologies to establish the connection for the users. They may use computer modems, fiber optics, TV cables, and telephone lines. Small businesses and individuals can use traditional options like copper wires for dial-ups, cable modems, asymmetric digital subscriber line (ADSL), etc.
For large and medium-sized organizations with consistent, high-speed internet needs, access provider ISPs offer ethernet, faster DSLs, synchronous optical networking (SONET), and more. In addition, they can also use satellite internet connections for disaster recovery, wireless access, etc.
Hosting ISPs
Web hosting companies can act as an ISP to offer services like web hosting solutions, online storage systems, email providers, cloud solutions, server operations, virtual servers, and more. Numerous hosting providers are available, such as Kinsta, offering exceptional performance, speed, scalability, and flexibility.
Mailbox providers offer services to host email domains with storage access for mails. They offer email servers for sending, receiving, accepting, and storing emails for organizations and individuals.
There are different levels of ISP providers. Upstream ISPs have larger networks than contracting ISPs, which provide access to contracting ISPs that can’t access parts of the internet by themselves. It works similarly to how customers pay for internet access: Contracting ISPs pay upstream ISPs.
The different levels are:
- Tier 1
- Tier 2
- Tier 3
- Networks
- ISPs
Virtual ISPs (VISP) buy services from other ISPs (or wholesale ISPs). They allow the VISP’s customers to use the internet operated and owned by the wholesale ISP.
VISP can be local exchange carriers to enable voice communication or mobile virtual network operators.
Internet Service Providers are the ones you must thank for opening the enormous world of the internet for you that’s filled with opportunities and fun. They help you support your business by offering internet connectivity and services so you can continuously serve your customers.
Whether it’s online shopping, chatting with friends from across the world on social media, or playing online games, the ISPs supply you with the capability to help you browse the internet with security, speed, and reliance.
So, when you choose an ISP, look for the type of connectivity available in your area, speed and bandwidth, customer support, SLA, and other points highlighted above to ensure you choose the right one based on your needs and budget.
