5 Common Types of Online PC Adapters and Ports Explained

When the very first computer was invented, it had just a display port for connecting the display. Today, modern computers carry a wide array of ports and adapters that allow them to be compatible with a large number of devices and accessories. Many older ports and adapters also evolved to accommodate modern media needs. Most of these ports and online PC adapters can be bought because of their standardized sizes and configurations.

Out of numerous ports, both custom and standard ones. These are the 5 most commonly used ports in computers:

Ethernet Ports


Internet connectivity is a must for any computer in today’s age, hence every computer comes with an Ethernet port. Wired internet is still unbeatable in terms of speed, stability, and reliability, so many businesses use wired internet connections that use the Ethernet port. One can even get an adapter if the computer lacks an Ethernet port, such as USB to Ethernet adapter.

3.5 MM Audio Jacks


Audio is as important to media as video, so 3.5 MM jacks, although shunned by mobile phone makers, still have a presence in computers and laptops. 3.5 MM jack is the standard audio jack that can play sound via any compatible earphone accessory or speakers. The latest slim laptops are skipping the legacy jack, so in their absence, a 3.5 MM jack adapter can be used for audio output. Audio adapters for PC can be bought online easily, and all adapters connect to USB-C ports.

HDMI


HDMI is the standard for video output and input, as no other port can do it better than HDMI. Modern HDMI standards have evolved a long way from the early days of video ports such as VGA ports, and often transfer audio in addition to video. HDMI ports are a standard in most computers, barring a few such as the latest MAC Book from Apple. In such cases, a USB-to-HDMI converter can be used, only if the USB port is capable of transferring video.

USB Ports


USB, like HDMI ports, have come a long way since their inception, both in terms of transfer speeds and capabilities. Early USB ports could only transfer power, whereas the latest ones can transfer power and data along with the video in case of advanced USB-C ports. Regular USB ports have been mainstream for computers, but they are slowly being phased out by USB-C ports that are much faster and more secure.

Card Readers


Card readers, although being phased into obscurity, are still present in many modern laptops. Card Readers come in mostly two types: Micro SD card readers and SD card readers. Micro SDs are smaller than SD and are actually their replacement. For laptops with only SD card readers, an adapter can be used to read micro SD cards, and adapters are also available for computers with no Card readers built-in.

USB 3.1 Type C Products Explained

Image
You might have heard about USB Type C- after all, USB ports are pretty ubiquitous in the world of tech and electronics. But do you know why USB 3.1 Type C product is different and why it’s kind of awesome? We will briefly go through the features and dive deeper into USB 3.1 type C. USB C is the newest generation of USB port, and it’s been getting a lot of attention lately. Its default protocol is USB 3.1 and the max speed is 10 Gbps. You will find this newer port on everything from smartphones to laptops. USB 3.1 (aka USB 3.1/gen 1 and USB 3.1/ gen 2) is the successor to USB 3.0. Identifiable by its port, USB 3.1/gen 2 doubles the transfer speed of 3.0 to a whopping 10 Gbps. USB Power Delivery 2.0 makes a big step forward as well with up to 100W of power. And like previous versions of USB, it is fully backward compatible with its predecessors. When used with the Type-C connection, things get interesting for 3.1. The 100W of PD v2.0 is enough to power and char

Detailed Breakdown of the Technology Used in Solid State Drives

Image
Solid-state drives, also known as SSD in short, are slowly replacing mechanical drives in computers. Mechanical drives are large and bulky, consume more power, and have a higher breakdown rate. SSDs are slimmer, have faster transfer speeds, and are long-lasting. HDDs will remain relevant for a few more years, as SSDs are still expensive and will take time to become affordable enough to completely replace HDDs.   ' Here is a detailed breakdown of components used in a solid-state drive: Connector: Serial ATA, also known as SATA, has been the standard for SSDs since its inception. They have already progressed to 3 generations, with SATA III being the latest standard. The connectors are still the same, with SATA I being compatible with SATA III connectors and vice versa. They only differ in terms of speed; SATA I supports speeds up to 1.5 Gb/s, SATA II up to 3 Gb/s and SATA III up to 6 Gb/s. Online PC adapters can be bought to connect SSDs and HDDs. SATA Express: SATA ex

Wireless networking with PCIe Adapters

Image
Peripheral Component Interconnect Express also abbreviated as PCIe, is how expansion cards communicate with your PC. It is a standard type of connection that has been around for several years but now there is an increase in adoption due to its speed for internal devices on a computer. Typically a PCIe adapter consists of one or more data transmission lanes connected serially, which can receive and transmit data. When you want to add wireless networking capability to your personal computer, without any second thought you can choose a PCIe network adapter. M.2 SSD to PCIe 3.0 X4 Card Speed: You might be thinking why not a USB wireless adapter as they are small, portable, and cheap but does that mean they are better than PCIe adapters? As compared to any other technology, say, SATA technology has a speed of up to 0.6 GB/s and PCIe enable interface speeds of up to 1 GB/s, which is capable of serving nearly every person in every network. But if your case is different
