A number of people overlook the importance of connectivity ports on the laptops while they are out to get a laptop for themselves. The reason is quite obvious; they just don’t understand how necessary these interfaces/ports are. And when they are done with the process of buying the laptop, the lack of relevant ports haunt them like ghosts.
In this article our aim is to give away some valuable information to the readers that will help them fathom the importance and relevance of the different ports that are found on the laptop bodies.
Expansion ports are different types of connection ports on a laptop that allow various kinds of external devices to be connected to the machine. There are numerous types of connectivity ports from the most basic USB till the latest Express card slot. So, let’s begin to explore all of them without further ado.
USB Port : Among all the connectivity ports the USB port is the most widely used interface. The USB lets you connect several types of devices to your laptop such as external hard drives, pen drives, cameras, keyboard, mice etc. It also helps in charging mobile phones and such small devices as it supplies small amount of power the connected devices. When the standard USB version 2.0 offers a transfer speed of 480 Mbps, the latest version 3.0 offers higher speed of 5Gbps.
ExpressCard Slot: ExpressCard slot is the largest Expansion slot on the body of your laptop. Devices might be plugged into the body of laptops via this slot. It allows devices like cellular broadband cards, memory cards, adapters, and network cards.
Thunderbolt Port: Thunderbolt port is a connectivity medium, which uses expansion bus to let the laptop be connected to the peripheral devices. It has been developed by the tech giant Intel and brought into the market by the Apple Inc. Now other companies also sport this interface on their respective devices.
HDMI Port: HDMI or high definition multimedia interface is relatively a new induction to the new age gadgets. The HDMI port is a compact audio/video connector that helps us to connect the laptops, tablets, or mobiles to the newer and popular entertainment things like HD LCD or plasma TV or HD DVD or BlueRay players. And it will not be wrong to say that with the help of HDMI on our machines we can connect to any high end electronic entertainment gadget.
Firewire/ IEEE 1394 port: Firewire is quite similar to the USB interface on all the fronts barring the technological one. It was first brought to light by Apple computers as the USB ports were lethargically slow at that time. Though, the USB 2.0 has, with its fast speed, has overwhelmed the Firewire a little bit but if it is inbuilt on your system it will only benefit you.
Memory Card Reader: Memory card reader is a slot, which is pretty common on modern day laptops as it allows you to insert any kind of memory card ranging from SD to 😄 to any other card like Sony Memory Stick into your system, hence better connectivity. Isn’t it a hassle-free method to transfer the pics from your camera by simply inserting the memory card in the card reader? This way you can avoid connecting USB cables to transfer the files. Some card readers even read 8 types of cards. It is a must on your system, readers.
VGA Connector: This is used to connect your system to any analog monitor or LCD TV. As we know that VGA is not a digital thing; it has been used to video connect devices for ages. It still remains relevant to the modern day laptops and is almost ubiquitous phenomenon.
External SATA or External Serial Advanced Technology Attachment: It is a means of faster data transfer. It is a bus interface which is used to connect host BUS adapters to the mass storage devices such as hard disks. It holds many advantages over the old interfaces like more efficient and fast data transfer and reduced cable size because it uses only 7 conductors instead of 40. A must port for every laptop.
RJ 45/Ethernet Port: RJ 45 is a jack standard registered for a modular connector that uses 8 conductors and is used to connect computers to a local area network (LAN) especially Ethernet. RJ 45 was previously a telephone thing standard. There was a time when it was considered indispensable but due to technological advances it has grown somewhat obsolete.
Modem Port: At the first glance one might take the modem port for standard telephone jack, but it is not the same. It connects an internal modem of a computer to a telephone line. And the modem of the system connects the computer to the internet by making a data call to a distant Internet Service Provider.
