What is 3G?

This is collection from India and Nepal.

Current WAP speed in India is nothing great but it has improved. I understand from my friends who are experts in telecom that you cannot improve the speed performance of WAP any further on a GSM network (which is 2G). I am told only 3G can improve things. So what is 3G? Continue reading “What is 3G?”

Software Project Planning

Software planning involves estimating how much time, effort, money, and resources will be required to build a specific software system. After the project scope is determined and the problem is decomposed into smaller problems, software managers use historical project data (as well as personal experience and intuition) to determine estimates for each. The final estimates are typically adjusted by taking project complexity and risk into account. The resulting work product is called a project management plan.

Content management systems

A CMS is a piece of software that manages website development. It can keep track of all changes to a website. It will record who changed what, and when, and can allow for notes to be added. A writer can create a new page (with standard navigation bars and images in the same location on each page) and submit it, without using HTML software. An editor can receive all the proposed changes, and OK them, or send them back to the writer to be corrected. If you are working in an organization that’s changing its website more than once a day, with several people working on it, using a CMS can bypass a lot of annoying problems, and save a lot of time.
