Difference between Leaptop & laptop

Posted by Suchismita | 7:28 AM

LapTop-- A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which usually weighs 2-18 pounds (around 1 to 8 kilograms), depending on size, materials, and other factors.

Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.

As Personal computers, laptops are capable of the same tasks as a desktop computer, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external keyboard or mouse can usually be attached.

While a Leaptop is meant for small kids from ages 3 and up to give them very basic knowledge...

Expandable Memory lets mobile devices use additional removable memory cards for increased storage space.

Memory cards are non-volatile, meaning they do not need power to maintain the information stored. In addition, memory cards offers fast read access times and better kinetic shock resistance over hard disks, ideal for storage on portable devices due to being able to withstand intense pressure, extremes of temperature and immersion in water. Different card formats exist in the mobile arena, varying in size and storage capacity

MMC (MultiMediaCard)

RS-MMC (Reduced-Size MultiMediaCard)

Memory Stick

SD (Secure Digital)

miniSD (Mini Secure Digital) .

microSD (Micro Secure Digital) / TransFlash

What is Netbook??

Posted by Suchismita | 12:50 AM

A netbook is a laptop computer designed for wireless communication and access to the Internet.

Primarily designed for web browsing and e-mailing, netbooks rely heavily on the Internet for remote access to web-based applications and are targeted increasingly at cloud computing users who require a less powerful client computer.

Netbooks typically run either Windows XP or Linux operating systems rather than more resource-intensive operating systems like Windows Vista.

The devices range in size from below 5 inches to over 13, typically weigh 2 to 3 pounds (~1 kg) and are often significantly cheaper than general purpose laptops..

Operating System

An operating system is a computer program that runs a computer and all its other programs
It is a software which organizes and controls hardware and software so that the device it lives in behaves in a flexible predictable manner.
It actually provides the platform to the hardwares like keyboard, mouse, CD drive, etc to run. It helps the computer to manage information and forms the basic working environment of the system. It is an interface between the computer and its application programs.

OS recognises the input from the input devices operates it & then produces out the output by displaying it on the screen or printing it out etc.It also keeps track of files and directories on the disk, and control peripheral devices such as disk drives and printers.I does CPU & memory management also.

Whenever we download or install any software, it is the OS who helps us in running it or we can say OS provides platform to run a program or software.

1. Windows
It is the most commonly used operating system & it is used worldwide. Microsoft windows has so many versions. Some of the versions are:-
Windows 7, Windows Vista, Windows XP, Windows 2000, Windows 98, Windows 2003, Windows ME, Windows 98, Windows NT, Windows 95 etc.
2. Macintosh
Macintosh was the most commonly used operating system before the Microsoft Windows.
3. Palm
4. Linux
5. Unix
7. NextStep
8. OS/2 Warp/eComStation
9. Sendla
10. Amiga

Even mobile phones use operating system

1. Symbian OS :- It is the most popular and widely used smart phone OS
