Many businesses today have discovered the many advantages of computer networks. The obvious question is which network will be the best for your home or business. There are 2 main options which are available: wireless networks and cable networks. If you plan on connecting many portable devices such as laptops or smartphones, you may want to take the wireless route. The disadvantage with wireless networks is they are generally slower and their latency is higher. Many companies still choose cable networks over wireless networks. The reason for this is the transfer speeds are extremely good. Today, Ethernet networks can achieve speeds of up to 1000mbps. You will be able to buy network card adaptors that either support cable or wireless networks.
