In 2010, for the first time, PCs cross a million a day. A million PCs a day - built, shipped, and sold in the industry. Intel CEO Paul Otellini predicts PC sales will double to 2 million units per day by 2014.

The scientific name for a computer is "Electronic Numerical Integrator and Computer" (ENIAC).

Lady Ada Lovelace's contributions can be seen in the field of computer science, particularly in her work with Charles Babbage on the Analytical Engine. She is often credited as the world's first computer programmer for her notes and algorithms created for the machine. Her writing and vision laid the groundwork for modern computer programming and algorithms.

Personal refers to something that is related to a specific individual or their feelings, experiences, or actions. Impersonal, on the other hand, refers to something that lacks personal connection or emotions, and that is often objective or detached in nature.

The first electronic digital computer, known as the ENIAC, was developed during World War II by John Mauchly and J. Presper Eckert in the United States. It was completed in 1945 and was used by the military to perform complex calculations that would aid in the war effort. ENIAC was a groundbreaking development that paved the way for the modern computer age.

Sony actually invented the first VCR. They developed both the VHS and Beta formats, and sold the rights to JVC for the VHS format because they believed the Beta format produced a better picture (which it did, by the way).

The reason the Beta format lost out was because of the availaible time that could be recorded on a VHS cassette. The VHS would hold up to eight hours on a tape and the beta maxed out around 4 or 41/2 hours of recording time.

The beta system could have stored more, but because of the physical size of the beta cassette, there just wasn't enough room to accomodate the extra amount of tape required. The beta format also required the tape to run through the recording heads at a faster speed to be able to record the additional picture image information on the tape.

Windows, MacOS, and Linux are the most common.

It depends on how well you take care of the laptop. If you just turn it on and off a lot of times during the day, and do not generally take care of it by cleaning it, or dusting it off, or protecting it from viruses and such, the laptop may only last a year or two. A really well taken care of laptop can last anyone around 10 years at the maximum care, but at around ten years, most features on the laptop may become obsolete. The average laptop can last between 2-5 years, and 10 if it taken really well care of.

Data processing consists of six basic steps: data collection, data storage, data sorting, data processing, data analysis, data presentation, and conclusions. Processes can be done manually, mechanically, or electronically.
