I would like to ask some internet related questions like why does a speed test for instance download is 3mbps which equivalent to 375kbps when it uploads at 30kbps? What are cables, dsl and adsl means? Can my router affect my internet connection and make it slower?
You would always want the download speed to be faster than upload speed. Download speed is the rate at which you pull out data from the internet. Upload speed is the gauge in you transferring your file to the internet. Download and Upload speed are always interconnected and your internet connection speed is quite ideal. As for cables, there are different kinds of them. LAN Cables which are either your straight through or cross over cables are the common cables used at home. Variations of these include CAT5, CAT5e, CAT6, etc. Another cable is fiber glass, which has tremendous transfer speeds are used for offshore services, primary networks in companies, etc. and there are more kinds of cables. ADSL is Asymmetric Digital Subscriber Line, has focus on download speed and capped off upload speed. DSL is Digital Subscriber Line, the common digital connection in this generation. A properly configured router (port forwarding settings, pool of users, etc.) can be of help in making your connection faster.
About the download and upload speed you are asking, both are particularly dependent on your Internet Service Provider and the plan you subscribed to. It is your Internet Service Provider or ISP who has full control over your internet connection speed. The actual download and upload speed is, most of the time, lower than the advertised speed of your subscription plan.
Your speed is also affected by the number of people using the service. This is one reason why at night, maybe from 7 PM to 10 or 11 PM, internet connection is bad because this is the peak hours or there are more people doing their thing on the internet. Cable, DSL, and ADSL are types of wired internet. DSL stands for “Digital Subscriber Line”.
With a DSL subscription, users get a high speed bandwidth connection using the phone line. This is the successor to the former dial-up connection and it allows you to make phone calls even while using the internet because DSL works within the frequencies that the telephone doesn’t. ADSL stands for “Asymmetric Digital Subscriber Line” and is one variant of the DSL service.
It was specifically designed to exploit the one-way nature of the majority of multimedia communication where large amounts of information flow toward the user and only a small amount of interactive control information is returned and provides an “always on” or continuously available connection.
