How long to transfer my file on my 1500kbps ADSL broadband?

First of all, you have an ADSL plan that is 1500kbps downstream and 384kbps upstream. SO if you are downloading a file from a high speed website, you should achieve 1500kbps, but if you are uploading the file to the same high speed site, you are going at 384kbps – assuming no one else is using the broadband.

 

So how fast this that? This is an estimate:

• Take 1500kbps (kilobits per sec.) divide by 8 = 187.5Kbps (kilobytes per sec.)
• Give and take 20% TCP/IP overheads on the bandwidth.
• So the actual throughput is around 150Kbps for download or 38.4Kbps for upload.
• If your file is 1MB or 1024Kb, you would need around 7 seconds to download or 30 seconds for upload.
• If your file is 1GB or 1024Mb, you would need around 7,000 seconds (116 mins or almost 2 hrs) to download or 30,000 seconds (500 mins or 8.3 hrs) for upload.

This is JUST an estimate, remember!

So see professional advise and do benchmark testing should you think of maximizing your bandwidth for file transfer or remote backups.

BTW, if you think you have a 8mbps, 10mbps, 25mbps or 100mbps broadband connection and enjoy that speed, you are in for a surprise!

Buying desktop PC? Better go for laptop/notebook!

If you are thinking of buying desktops for office use, it is time to consider laptops/notebooks/netbooks! Reasons are: -

• Desktop PC uses more electricity!
• Laptops/notebooks/netbooks uses less power and the battery acts as a UPS/backup power!
• Laptops/notebooks/netbooks can be cheaper than desktops PC.
• Laptops/notebooks/netbooks is almost as fast as desktops PC, and more portable!

Lets look at electric power. I visited http://services.spservices.sg/cs_services_energy-audit.asp and did an estimation, see results returned for each item: -

Thank you for using the Home Electricity Audit.
Your estimated electricity consumption in a month is:
840 kWH or $210.59
(Based on the current tariff rate of 25.07 cents/kWH)
This is a breakdown of the electrical appliances which contributes to the electricity consumption in your home:
Description	Electricity consumed per month (kWH)	Electricity Cost per month ($)
Computer – 300W	720	$180.50
Notebook – 50W	120	$30.08

So for each item, 10 units of notebooks (8 hours per day)’s power usage only S$30.08/month, a wooping savings of S$150.42 X over a period of 36 months = Saved S$5,415.12!

Therefore 3 years later, you can own new additional 3-5 more notebooks with the savings if you switch to laptops/notebooks/netbooks today!
