What is a Cable Modem?

A cable modem is a peripheral device used to connect to the Internet. It operates over coax cable TV lines and provides high-speed Internet access. Since cable modems offer an always-on connection and fast data transfer rates, they are considered broadband devices. Dial-up modems, which were popular in the early years of the Internet, offered speeds close to 56 Kbps over analog telephone lines. Eventually, DSL and cable modems replaced dial-up modems since they offered much faster speeds. Early cable modems provided download and upload speeds of 1 to 3 Mbps, 20 to 60 times faster than the fastest ... Read more

What is FTP?

Stands for "File Transfer Protocol." FTP is a protocol designed for transferring files over the Internet. Files stored on an FTP server can be accessed using an FTP client, such as a web browser, FTP software program, or a command line interface. An FTP server can be configured to enable different types of access. For example, an "anonymous FTP" configuration allows anyone to connect to the server. However, anonymous users may only be allowed to view certain directories and may not be able to upload files. If anonymous FTP access is disabled, users are required ... Read more

What is DSL?

Stands for "Digital Subscriber Line." DSL is a communications medium used to transfer digital signals over standard telephone lines. Along with cable Internet, DSL is one of the most popular ways ISPs provide broadband Internet access. When you make a telephone call using a landline, the voice signal is transmitted using low frequencies from 0 Hz to 4 kHz. This range, called the "voiceband," only uses a small part of the frequency range supported by copper phone lines. Therefore, DSL makes use of the higher frequencies to transmit digital signals, in ... Read more
