How Is Network Performance Measured Basic Guide!

Internet speed is measured in bits per second

First of all, this guide may help newbies around the globe, it’s not that you know already lets someone get knowledge who never considered on such measurements.

Computer network performance — sometimes called internet speed — is commonly measured in units of bits per second (bps). This quantity can represent either an actual data rate or a theoretical limit to available network bandwidth.

Explanation of Performance Terms

Modern networks support enormous numbers of bits per second. Instead of quoting speeds of 10,000 or 100,000 bps, networks normally express per second performance in terms of kilobits (Kbps), megabits (Mbps), and gigabits (Gbps), where:

  • 1 Kbps = 1,000 bits per second
  • 1 Mbps = 1,000 Kbps
  • 1 Gbps = 1,000 Mbps

A network with a performance rate of units in Gbps is much faster than one rated in units of Mbps or Kbps.

Examples of Network Performance Measurements

Most network equipment rated in Kbps is outdated and low-performance by today’s standards.


The following are some common speeds and capacities:

  • Dial-up modems support transmission rates up to 56 Kbps.
  • The Federal Communications Commission requires broadband internet connections to have download speeds of at least 25 Mbps and upload speeds of at least 3 Mbps.
  • Theoretical speed in a home network using an 802.11g Wi-Fi router is rated at 54 Mbps, while newer 802.11n and 802.11ac routers are rated at 450 Mbps and 1300 Mbps, respectively.
  • The gigabit Ethernet in an office has a transmission rate approaching 1 Gbps.
  • A fibre-optic internet provider often reaches actual download speeds of 500 Mbps.

Bits vs. Bytes

The conventions used to measure the capacity of computer disks and memory appear similar at first to those used for networks — but don’t confuse bits and bytes.

Data storage capacity is normally measured in units of kilobytes, megabytes, and gigabytes . In this non-network style of usage, the uppercase K represents a multiplier of 1,024 units of capacity.

The following equations define the mathematics behind these terms:

  • 1 KB = 1,024 bytes
  • 1 MB = 1,024 KB
  • 1 GB = 1,024 MB
