Reorder the following speeds in ascending order (from lowest to highest)

• 1000kbps

• 100mbps

• 1000mbps

• 1GBps

• 10gbps

Answer explanation

Speed generally refers to the maximum rate you can transmit data. Typically, this is measured in Mbps, however there are many.

1) Kbps: Kilobit(s) per second; no-one nowadays uses this measurement, hence this is considered the lowest. 1000kbps = 1mbps

2) Mbps: Megabit(s) per second; this is the standard that many companies use. 1000mbps = 1gbps.

3) Gbps: Gigabit(s) per second; typically, this is used when there are many devices that are simultaneously connected i.e. companies or big households may use. 1000gbps = 1tbps

______ is when a movie or music downloads faster than generally

Answer explanation

Buffering occurs when a movie or music track plays faster than it downloads.

For instance, you are watching tiktok and the videos start and stop; this is generally because the internet speed is much more slower.

However, companies such as TikTok, YouTube, Netflix, Disney+, etc; they store some of the file in a buffer until it can begin playing the whole video.

This is why sometimes your internet may drop but you can still watch TikTok,.
