History:

Charles Babbage, an English mechanical engineer, and polymath was the first one to originate the concept of a programmable computer. Thus, he came to be known as the ‘Father of Computers’. Alan Turing suggested the theory of modern computers.

As the use of personal computers became more workable in 1971, the idea of portable personal computers soon followed. Alan Kay, at Xerox PARC in 1968, imagined a ‘personal, portable information manipulator’. The IBM 5100 was the first portable computer that appeared in September 1975 to be commercially available.

Talking about the projectors, there have been a few pieces of evidence that have been found in history. People at that time were not able to differentiate between the use of lantern projection and shadow play.

The tablet computer and its associated operating system came into existence with the development of pen computing. Early as 1888, electrical devices with data input and output on a flat information display existed with the telautograph.

The first computer printer design was the first mechanical-driven printer by Charles Babbage for his Difference Engine in the 19^th century, but it was not built until 2000. The first electronic printer was the EP-101, invented by the Japanese Company Epson and was released in 1968.

Types of Accessories:  

1. TABLETS – The range of Android tablets on the market makes it hard to compile specifications. Android tablets are just specialized computers in reality. A version of Google’s mobile operating system runs on all Android tablets. Older tablets could be stuck with a smartphone-designed Google operating system. Some Android apps may not be able to run the older versions of the operating system. The older the Android version, the fewer applications the computer will be able to run without problems.

• APPLE iPads – Each year, Apple launches a new iPad lineup, and although there are always a few key changes, the device largely stays the same. This is because the computer is still, for the most part, an iPad. It may be quicker, slightly lighter, and slightly faster, but most of the functions are still the same. Even the name appears to remain the same. Some of the important features of an Apple iPad are as follows:
• Retina Display
• Multi-Touch Display

• PROJECTOR – Nearly everyone is expected to convey to clients or colleagues the material, intent, and importance of his or her work. By extending the picture of your computer screen to be big enough for a room full of people to see, projectors assist the contact. When you choose a projector, by assessing its features and characteristics, you need to be confident that it meets your needs.
• Compact and lightweight design
• High brightness and low fan noise
• Superior Image Quality
• Simple Operation
• 3-D Digital Convergence.

• PRINTER – A color printer is a printer that enables color prints to be produced for pages or other objects. Color printers have developed over a number of decades to produce higher efficiency and sophisticated outcomes, including color televisions and other forms of equipment and consumer goods. Some of the features of the printer that one has to look for:
• Type of Printer – Inkjet vs Laser
• Ink type – Monochrome vs Color
• Print Speed
• Duplex Printing Support
• Automatic Document Feed
• DPI – Print Quality
• Paper Tray Capacity
• Cartridge Capacity
• Scanner Resolution
• Copy Speed
• Printer memory / RAM
• Security and Encryption Support

• SCANNER – In the abundance of other office equipment, scanners can be ignored, but they are increasingly vital to the productivity of your business. Here are some of the main scanner features to remember before purchasing a scanner:
• The Feeder Type
• Compatibility of the Software
• Color Depth and Resolution
• Scanning Bed Size
• Extra Amenities
