Activity #1

1. Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT).

2. Data are simply facts or figures — bits of information, but not information itself. When data are processed, interpreted, organized, structured or presented so as to make them meaningful or useful, they are called information. Information provides context for data.

3. Input Devices

A digital camera or digicam is a camera that captures photographs in digital memory. Most cameras produced today are digital, and while there are still compact cameras on the market, the use of dedicated digital cameras is dwindling, as digital cameras are now incorporated into many devices ranging from mobile devices to vehicles. However, high-end, high-definition dedicated cameras are still commonly used by professionals.

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. 

4. Output Devices

a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.



5. Storage Devices

A CD-ROM (/ˌsiːdiːˈrɒm/) is a pre-pressed optical compact disc which contains data. The name is an acronym which is short for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs, which are not writable or erasable.
