What is Broadband?
Broadband is a high-data-rate connection to the Internet. The technology gets its name as a result of the wide band of frequencies that’s available for information transmission. Information can be multiplexed and sent on numerous channels, allowing more information to be transmitted at a given time.
The standard broadband technology in many areas is cable Internet and asymmetric digital subscriber line (ADSL), but newer technologies, such as VDSL, cable, fiber optic and wireless broadband are becoming more widespread. Broadband is also known as wideband.
Broadband allows users to access the Internet and its related services at higher speeds than those available through dial-up Internet access services.
The speeds differ based on the type and level of services offered. There are two groups of broadband technologies: fixed-line broadband and wireless technologies. Fixed-line solutions communicate through physical networks that provide direct wired connection from customer to service supplier. Wireless solutions, on the other hand, use radio or microwave frequencies to provide connections between operator and customer networks.
Unit Measurement of Data:
Data usage is usually measured in units known as gigabyte (GB) megabyte (MB) or kilobyte (KB), with 1MB = 1000 KB and 1GB = 1000 MB
What is Bandwidth?
Bandwidth generally refers to the volume of information per unit of time that a transmission medium (like an internet connection) can handle. An internet connection with a larger bandwidth can move a set amount of data, like a video file, much faster than an internet connection with a lower bandwidth. Bandwidth is typically expressed in bits per second, like 60 Mbps or 60 Mb/s, to explain a data transfer rate of 60 million bits (megabits) every second.How much bandwidth you need depends on what you plan on doing with your internet connection. For the most part, more is better, depending on your budget. Using plumbing as an analogy, data is compared to available bandwidth, as water is compared to the size of the pipe. As the bandwidth increases, so does the amount of data that can flow through in a given amount of time, just like as the diameter of the pipe increases, so does the amount of water that can flow through during a period of time.
Personal Activities: How much Internet data are you using?
The table below shows how much data some standard online activities may use. These figures are only rough estimates and your actual usage will vary based on a number of factors.
Commercial Activities: How much Internet bandwidth does your business need?
Factors to consider when calculating bandwidth needs
Some simple calculations can predict what you’ll get in terms of network traffic. Planning ahead can ensure that applications that take up a lot of bandwidth, like VoIP video calls or video conferencing, won’t slow down your internet to the point that you can’t get other work done. It’s also important to remember that as you increase the number of simultaneous internet tasks, the speed of each one can decrease. Your internet service has a maximum speed and your tasks will slow down as you approach that maximum threshold. You can increase your internet speed/bandwidth, or plan around doing things at the same time. For example, you can schedule data-intensive backups to occur after business hours.
The table below can help with determining data traffic and bandwidth requirements
1. Determine how many people will use your internet at the same time.
2. Factor in what they will be doing.
3. Calculate the bandwidth needed per task.
4. Total up the bandwidth you need for all tasks happening at the same time.
