The area of the computer networking is full of computer networking equipments. There are many layers of computer networking, so there are hundreds of computer networking equipments for all. Since there are hundreds of computer networking equipments used at present, it is worthwhile to have a look at a few of them.
Routers are one most important computer networking equipment in the field of computer networking. These devices make sure that the data communication correctly takes place between the network devices. As an example, if you want to explore the Cyberspace for something, you will open a web browser and type the web address (URL) of the website you want to navigate and press enter. Then the browser tries to figure out the website and load the web pages stored in the website.
For this, the router makes sure that the data communication between the computer and the Net is smooth and proper. Unless there is a router engaged for home computing, it is virtually impossible to have broadband Internet at home.
Next, the network interface cards or the devices are the most important category of computer networking equipments. These are connected to the device which needs to be networked. Usually almost all the laptops and desktops do carry network interface devices by default at present. When it comes to laptops, there are wireless network interface devices installed as well. There are many forms for network interface devices.
First of all, they came in ISA card form and they are no longer in use. Then it changes itself to a PCI card and PCI cards are still in use for desktop computers. For laptops, network interfaces are internal. When it comes to linking the computers to the network, RJ45 cables, or in other words the network cables are connected to the network port of the network interface card.
The hub is one of the important equipment which also has kind of a universal use when it comes to computer networking. This computer networking equipment connects multiple computers locally where the computers can find and access one another. Due to the advance capabilities of hubs, bandwidth and latency in accessing the rest of the network have enhanced. This device performs the same jobs as a router, other than the ability of connecting the Internet to the computers.
Since the hubs and switches look the same, many people make mistake when identifying them. They think both the devices perform similar jobs. Dissimilar to hubs, switches are employed for connecting two or more networks so they can perform as a single network.
