I am working for a local web development company and I have been asked to help design and develop Alumwell B&E College’s (ABEC) website. Throughout this project I will meet with my project manager to clarify the website requirements in more detail and report my progress. In addition to the design and creation of the website I will look at the security, legal and performance issues involved with web development. I will compose a report which focuses on the user and server side factors that influence website performance.
User Side Factors
Download speed is the speed that data or a program can be transferred from a central computer or website to a peripheral computer. The internet speed of a user’s internet connection determines how fast you can browse within the internet, how fast pages, pictures or videos load.
There are four types of different internet connections including, dial-up, ISDN, DSL and Broadband. Dial-up is a connection that is inexpensive but slow. It uses a modem connected to a PC, users can then connect to the internet when the computer dials a phone number and connects to the internet. The modem converts received data to digital and vice versa. Because dial-up uses telephone lines the quality of the connection is not reliable and data rates are limited. A dial-up has an average speed from 2400bps to 56Kbps. It isn’t used widely today as it has been replaced with more efficient options like DSL and Broadband.
ISDN is another internet connection. It stands for Integrated Services Digital Network. It is an international communications standard for sending voice, video and other data over digital telephone lines or normal telephone wires. The average speed ranges from 64kbps to 128kbs.
