Barcode Readers

A barcode scanner is a device designed to read barcodes printed on a retailer’s products for the purpose of stock control and to recover the latest pricing. They are also known as barcode readers and they are electronic devices that have a light source and a light sensor, used for translating the optical image of the printed barcode into an electrical image. The electrical information can be linked to an electronic till or some form of computerised system designed to read the information.

Handheld barcode scanners are probably the most popular because of the flexibility of movement and the mobility they provide. A handheld barcode scanner can be used by an operator to locate the barcode and run the scanner over the barcode.

Desktop barcode scanners are also very popular and can be found in may retail outlets such as department stores and supermarkets where the item containing the barcode is located over the scanner in order to obtain the image. They can often be co-located with handheld scanners so operators can locate barcodes placed on awkward areas of a product.

Cloud Computing Intro For Beginners

The Internet and email each revolutionized the world in their own ways, and cloud computing looks all set to be the next iteration. There are libraries full of books on this subject, each with a different view of what it means. The simple definition is that the internet is used to provide on-demand access to resources, data and applications.

This functions in a way similar to utilities such as an electricity grid. A user just opens up a browser and accesses the required application and/or resource. The user then gets billed based on the usage, same as with utilities.

In order for this to work, providers offer data centers which simultaneously handle the resource requests from multiple clients. With everything in the data centers, the company does not need to have its own IT setup. This means companies can get rid of existing setups and the associated staff.

What Is A mp3?

The mp3 is type of format for digital music that is used to create sound files of a high quality. Since the inception of the mp3, listening to music has never been the same. Perhaps the greatest attraction of the mp3 is that it is able to compress files into more versatile and convenient files.

The quality of sound in the mp3 is quite similar to the older music formats although there is no chance of skipping due to the fact that mp3s do not have moving parts.

How the mp3 Works

The mp3 compresses the music files by removing out many of the song’s sounds that the ears are incapable of hearing. The file then uses complex mathematical equations in order to further reduce the size of the files.
Due to the extent of the file’s compression, the result is a track that is approximately eleven times smaller in size than their music file predecessors.

What Is an IP Address?

It is a default private IP for various NAT/network devices such as routers. In order to resolve the issue of shortage of IP to be used on the Internet, these IP addresses were devised. RFC 1918 defines the ranges of the private IP.

An IP, where IP stands for Internet Protocol, is a numeric identification that is assigned to all the devices or machines, which are a part of any computer network. All the devices, which are connected to a network, have a unique IP. As we have said earlier, these addresses are numeric representations, which are divided into four parts, and each part is separated by a period (dot) between them. For instance, an IP normally looks like 192.168.1.1.

One series of these numbers is classified as private IP. Generally, this set of numbers range from 192.168.0.0 to 192.168.255.255. Each of these numbers is retained and unique as compared to other IP addresses. The word unique here is used in the sense that these numbers are unique within the network they belong. To make this clear let us take an example of your college or office computer, which is assigned an IP 192.168.1.1 in network and you, will have the same IP address in your home network as well and it won’t create any conflicting issue.

Files, Folders and Defrag – Help Organise Your PC

A file on your computer is much like a file that you would keep in your filing cabinet. Each file has a unique name and is kept in a specific location. Each computer file has a three character extension which is separated from the file name by a period. The extension is often hidden however there is an option in Windows to display this if you wish. The extension relates to a specific program. This tells the computer which program to open it with. For example, a file extension xls or xlsx relates to Microsoft Excel.

Some file extensions, such as.mp3 can be opened in a variety of programs.

What is a Folder?

A folder usually contains a collection of files similar to a folder in a filling cabinet. You can have folders within a folder. These are known as subfolders. You may sometimes hear folders referred to as directories.
