When you use something in daily life, you must know about the basics of the device. Laptops and Computers have various connectivity ports on the sides. Each port has its significance, but we will provide you a detailed explanation of it. It’s very important to check for your required port before buying your new laptop. The different types of ports are –
Universal Serial Bus (USB) is the most common type of port on a Computer or Laptop. The purpose of the USB port is to transfer data from one device to another (like Laptop, Computer, smartphone, printers, etc.). There are different versions of USB ports – USB 1.1 (transfers data at 12 megabits per second), USB 2.0 (hi-speed USB transfers data at 480 megabits per second), and USB 3.0 (Superspeed USB transfers data at 5 gigabits per second).
Usually, laptops offer two to three USB ports (except MacBook Pro that has only one port available). You can also use the USB for charging small devices like smartphones, Bluetooth speakers, etc. There are three types of USB ports – USB type – A, USB type – B, and USB type – C.
- USB type A: It is the most common type of USB port. It is available on almost all laptops and computers.
- USB type B: It is a type of USB that connects into a peripheral device (like a smartphone, printer, etc.).
- USB type C: It came into action when Apple’s 12-inch MacBook was launched with type C design.
Micro USB port
It is also known as Micro-B and is used as a charging connector to charge low-power devices like smartphones, tablets, Bluetooth speakers, etc. It supports USB 2.0 speed that is 480 Mbps. But some external hard drives have a micro USB 3.0 port with some extra pins and offers faster transfer of a file.
Mini USB port
It is also known as Mini-B port. It is not a widely used USB port; hence you can’t find it in most devices like smartphones, tablets, computers, etc. But few devices support Mini USB ports, and there it can play the role of primary importance.
Today, most of the devices (laptops and computers) come with Wi-Fi enabled features that allow internet access without wire connections. Therefore, we need an ethernet port to connect the device to the internet. It is also known as Registered jack – 45 (RJ-45) or Jack or Socket ethernet jack. Ethernet cables come with LED lights that indicate the signal strength. It is found on business laptops and desktops. Ethernet ports are beneficial when you stay at hotels or a place where the wireless network is slow.
We use the high definition multimedia interface (HDMI) ports for transferring video and audio signals from your laptop to TV, other laptops, projectors, etc. It has different versions. Out of them, the latest port is HDMI 2.1. But we can easily find HDMI 2.0 and HDMI 1.4 in older laptops and computers. Depending on your laptop’s graphics card, the HDMI port may provide an output of up to resolution.
SD Card Reader
It is also known as 3-in-1 card reader or 4-in-1 card reader or 5-in-1 card reader or SDHC card reader. You can use an SD card when you want to transfer files to and from the card. The most common use of an SD card reader is that you can use it to read the memory from digital cameras to transfer pictures from a DSLR or mirrorless camera to your device (laptop or computer). There are older computers and laptops in many households that do not contain SD card reader functions. The alternative for them is that they can purchase an external USB based reader to read the data from SD cards.
Displayport or mini display port
It is similar to the HDMI port and used to transfer audio/video signals from one device to another. It is of two types – Standard Display port and mini DisplayPort. As the name suggests, small-sized laptops come with a mini Display Port, and bigger ones come with the standard display port. The standard display port can produce an output of 4k resolution at 60 Hz. Most laptops have display ports, and like HDMI cable, display ports can produce output audio and video on the same cable.
Digital Visual Interface (DVI) is an ideal port to connect TV monitors to display videos. DVI-I is the most common DVI type. It offers higher bandwidth than an HDMI port and is an excellent choice to get most out of a high frame rate. DVI can produce an output of up to 1920*1200 at 60 Hz (standard refresh rate). To create an output of 2k or 4k resolution using a second connection (like aka and dual-link DVI)
Video graphic array (VGA) port is standard in computers. It comprises 15-pins for connection to transmit video signals from CPU, projectors to monitor screen. The negative part about this port is that it is not compatible with transferring HD resolution videos and, hence, sending outputs up to 1920*1200.
All the modern devices (smartphones, laptops, computers, etc.) come with an audio jack or headphone jack. An audio jack’s standard size is 3.5 mm (except iPhones and Pixel Smartphones that have unique designs of audio jacks).
It looks similar to a USB type C port, but their functions are different. Unlike HDMI type C thunderbolt 3 supports a speed of 40 GB per second. Hence flash three can work as HDMI type C, but the reverse is not valid.
All these ports are of great utility, and hence a laptop is incomplete without them. These are essential parts of a computer or computer. Therefore, before you shop for a new device, keep the ports in mind so that you can get the best product. The number of connectivity ports varies with the type of computer you have (Desktop Computer, Laptop Computer, Tablet Computer, or a Smartphone).
