What is computer speed?


Updated: 08/03/2018 by Computer Hope

Speed may refer to any of the following:

1. In general, speed is the overall time something takes to complete. For example, if a computer is fast it will open program in less than a few seconds depending on the size of the program. Often many fast computers can open smaller programs in less than a second. However, if a computer is slow it can take several seconds or maybe even a minute or more to open a big program.

Tip: See our slow definition for all links related to why a computer or parts of a computer (e.g., Internet) may be slow.

There are several factors that contribute to the overall speed of a computer. These factors include the processor, cache, memory, bus, hard drive, video card, operating system, and software. A full breakdown of how each of these components affect the speed of a computer is on the following pages.

2. When referring to the Internet speed and network speed, speed or high-speed should be referred to as bandwidth, which is how much data the connection is capable of transferring. For example, a dial-up modem is capable of a small amount of bandwidth (at most 56.6k a second) and a broadband connection has a much larger bandwidth, typically several MB a second. Your connections maximum bandwidth, the remote computers bandwidth, the latency, and number of hops between the two computers all determines your Internet speed.

Note: Keep in mind that your connection may be an asymmetrical connection, which means it has a different download and upload speeds. For example, a broadband cable modem connection has a faster download speed than upload speed. Although most of what people do on the Internet is download, when using VoIP or other upload intensive service, the upload speed is another contributing factor to the overall Internet speed.

3. The access speed or drive speed is how fast a computer drive can read and write data. For example, one of the factors that determine a hard drive speed is the rotations per minute (RPM). A hard drive that only spins at 5400 RPM will have a slower drive speed than a hard drive that spins at 7200 RPM. Solid-state drives (SSDs) that have no rotating platters can still be benchmarked by determining the IOPS.

4. The mouse speed or touchpad speed is how fast the mouse pointer moves on the screen. If the mouse cursor speed is too slow or too fast, it can be adjusted through the operating system or software installed with the mouse.

5. The printer speed is how many pages per minute (PPM) a printer is capable of printing. See our PPM definition for further information on this term and related printer speed measurements.

6. The speed at which you type or your typing speed is measured by words per minute (WPM) and GWAM. See our WPM and GWAM pages for further information and related links on these terms.
