Type of Connectors Used in a Laptop
Connectors are found in most electronic devices; Laptops come packed with a variety of these components. A better understanding of the connector ports present in a laptop can help increase efficiency and ease of use.
Connecting a portable USB drive or external hard drive via the USB port is no longer a big deal. Anyone with a laptop will be familiar with USB ports; however they might not be aware of different variants in the market such as USB 1.0, USB 2.0 and USB 3.0. These are classified on the basis of speed performance and efficiency.
While USB 1.0 is the slowest, USB 3.0 can give you the highest data transfer speed. USB 1.0 and 2.0 are very similar and easy to identify. They have a rectangular metal interface with four connection pins made of brass. USB 3.0 is a newer version and offers very fast; although they are similar in shape, they have nine connection pins. USB 1.0 and 2.0 can be exchanged in place of each other, while USB 3.0 can only be used in devices specified for this type of connector.
Audio connectors are another common finding in laptops. Previously, laptops featured a phono plug that offered mono sound. This has been upgraded to dual phonos providing stereo sound. These days, a single stereo jack with a microphone input is used. These connectors are used to transmit audio signals in and out and are easily identified by their small circular design.
The latest laptop models come with the HDMI connector (High Definition Multimedia Interface), which helps to connect to a modern High Definition TV for video transmissions. HDMI connectors have largely replaced the VGA output used in older laptops to transmit video signals to larger monitors or televisions. These HDMI connectors have two rows, one with nine pins and the other containing ten pins, which account for a total of nineteen connections. On the other hand, VGA connectors had three rows with five pin holes in each row in a rectangular shape with curved ends. HDMI connectors offer improved video quality with more contact interfaces.
In addition to these connectors, the RJ45 connector is present for the network connection. It comes with a square design and eight brass pins. The cable is held to the connector by means of a catch. These are usually used to connect the router box or network cable directly to the laptop. Older laptops had a smaller version of this connector, which only had four pins. This was used to get an internet connection through a landline.
Understand the purpose and method of connection, to ensure the long-term efficiency of your gadget. In addition to this, many high-end connectors such as PCI Express (PCIe), Board-to-Board, M.2, SAS, SATA, and DDR4 memory module sockets are used in the laptop box, and they are not visible to the consumer.
