Generation of Computer

Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.

The iPad is one of the hottest gadgets of 2010

The iPad essentially revolutionises the concept of a tablet computer. Previously tablet devices addressed a legitimate consumer need (casual, lazy, couch-bound computing), but left most people frustrated with a stylus-driven handwriting recognition system and an operating system that was really designed to be used on a desktop PC.

The Technology of Mobile Phone

Mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these more general computing capabilities are referred to as smartphones.

The Technology of Internet

The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.

The Categories of Software

Software is often divided into application software (programs that do work users are directly interested in) and system software.

mathematical formulas. Spreadsheets are indispensable tools for anyone who works with numbers.



USAGES OF SPREADSHEET SOFTWARE
