In computer terms, a memory stick is a small, portable electronic storage device. Memory sticks are mostly used in portable devices, like digital cameras, to store electronic data. In the case of a digital camera it will store photographs. Most modern computing devices, for example computer laptops, have ports where you can plug in the memory stick to download or copy the data from the memory stick to the computer.
The term memory stick was first created by Sony to describe their flash memory devices but today, the term memory stick, is used to describe these types of devices in general.
A pixel is the smallest measurable and addressable unit of a raster image on a computer or electronic display. A single dot in this cartoon image can be referred to as a pixel on the computer screen.
One Mega pixel (MP) is in fact a million pixels. Mega pixels, are used to indicate the number of pixels in an image, the number of image sensors in digital cameras or the number of display elements of electronic or digital displays.
The Kindle is an electronic device used for reading electronic books or e-books. The Kindle is developed by Amazon and hugely popular under e-book consumers. The e-books can be purchased online from Amazon or various other e-book retailers.
The Kindle can be used in bright sunlight and can be used for up to a month on a single charge (with wireless off). It can store up to 3500 books and is the number one best seller on the Amazon web site.
In computer or electronic terms a clock cycle is a single electronic pulse of the internal oscillator that drives the speed of the internal circuitry like the CPU. The oscillator is designed to run at a specific frequency and is measured in hertz.
Modern computers runs in the region of a couple of Gigahertz (GHz)
A CPU fan is a cooling fan used to cool a computer’s processor or CPU (central processing unit). It is usually used in conjunction with a heat-sink to dissipate the heat generated by the processor. Some computer systems can detect the CPU temperature and control the CPU fan speed accordingly.
In computing terms, a mouse is a device that is linked to a computer and used as a pointing device. The mouse is usually equipped with one or more buttons and a sensor or ball underneath to detect movement. A mouse is used on a flat surface or on a special mouse pad. The mouse is shaped in such a way to comfortably fit into the palm of the computer user’s hand. The mouse controls the movement of the pointer (an arrow by default) on the computer screen. The computer mouse comes in various shapes and sizes with varied functionality. Some examples are:
The gaming mouse is a variable resolution device, specifically designed for computer games and comes with a number of cotrollalbe buttons. Most of them can be programmed to perform specific gaming commands. These mice are designed for speed and accuracy.
The original design of the computer mouse used a ball to detect the movement across the surface the mouse is resting on but modern designs use optical sensors to accomplish this. These optical sensors are more accurate and less prone to physical damage.
The Apple mouse is a mouse designed by the Apple Inc computer company and used with the Apple range of computers. The original design of the apple mouse had only one button where most mice have more than one.
A cordless mouse is a mouse that is not linked to the computer via a physical cable but makes use of electronics signals to communicate with the computer.
The laser mouse uses a laser sensor to detect movement and is used in high precision applications.
