A network card is a component of a computer system unit or a part of a laptop that allows connection to the Internet or a local network through an external interface. Converting data sent from a PC or receiving packets of information to it can be done wirelessly via Wi-Fi or wired - by directly connecting a cable to the port. You can look for a new device, or you can buy a used network card for a PC for very modest money. The quality is unlikely to change, the main thing is to study the parameters of the device.
Characteristics of network cards
The card receives and transmits data from PC to PC or is part of a network and provides communication between devices. Its tasks include preparing information for sending, using a transceiver to convert data into serial data, some models support encryption and send packets. When receiving, the process is reversed. Each card has a unique address that allows you to identify the source and target of the data stream.
A modern computer network card can have a number of characteristics that you should familiarize yourself with before buying. There is a standard classification of network cards:
- built-in,
- external,
- internal.
Network card parameters:
- data packet transfer rate,
- manufacturer,
- network adapter interface.
The transmission speed can range from 10 to 1000 Mbps. The higher the rate, the faster the information is transmitted. The highest performance is provided by fifth-generation Gigabit Ethernet technology.
There are models from different companies on the market. The highest quality are used network cards from:
- TP-Link,
- D-Link,
- Dell,
- Edimax,
- HP,
- Tenda.
The connection interface can be PCI Express or USB. PCI is used for built-in cards, and USB is used for external cards, for example, in laptops. A USB network card makes it easy to use the Internet anywhere. Buying a used network card with Wi-Fi is a solution that eliminates the need for cables. The transmission is carried out through the air via a built-in or external antenna.
Some network cards have their own RAM. Simple ones reserve space on the PC's RAM, while more sophisticated ones use their own. Gaming cards are usually equipped with their own memory.
