BANDWIDTH
• In computing bandwidth describes the maximum data transfer rate of a

network or Internet connection
• Bandwidth is measured as the amount of data that can be transferred from
one point to another within a network in a specific amount of time
• Typically, bandwidth is expressed as a bitrate and measured in bits per
second (bps)
• The term bandwidth refers to the transmission capacity of a connection and
is an important factor when determining the quality and speed of a
Description network or the internet connection
• For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps
(125 megabytes per second)
• The difference between internet speed and bandwidth is : Internet
bandwidth is about how much data can be download or uploaded from
your computer, while Internet speed is how fast can the data be uploaded
or downloaded on your computer
• Streaming video - Netflix, YouTube and Hulu all require substantial amount
of bandwidth for smooth, high-definition video delivery
• Cloud Applications - Cloud services offer you the advantage of accessing
your data using multiple devices and you can connect to the Internet from
anywhere, but these services can also require significant bandwidth
especially if not properly configured. Some cloud storage services allow you

treating the online storage as if it were simply another folder on your hard
drive.
• Malware - A sudden spike in bandwidth usage can also be the fault of a
malware infection. Many types of malware attempt to disable your system’s
security features to allow the author of the program to take control of your
computer, turning it into a "zombie."
