Easy Tutorial and Guide Use a Digital Voice Recorder

Digital voice recorders are useful compact devices, which are used for recording voice data. They have an improved sound quality due to the advanced sound technology. Scroll down to learn more about this device along with information on how to use it.

Well, this device functions almost in the same way as a tape recorder, except that, it doesn’t have a tape. As the recording and listening process is easy and quick, it is widely used by students, interviewers, academicians, journalists, etc., to record their voices and re-record them if they choose to. Digital voice files are incorporated to record the voice data. The voice data is stored in the form of discrete numbers, and the value depends on the air pressure involved during the voice modulations. But the input is a continuous stream of analog data. The analog signal is converted into digital signal by Analog-to Digital Converter (ADC). The output of the ADC is in the form of stream data consisting of 0s and 1s, which is stored in the memory and later converted to analog data. It is important to convert the digital data into analog data, because, we can hear only analog signals.

How to Use This Device

This device looks like a USB device, it’s just that it records voice data. Its three main components are:
1. Microphone , to capture the sound waves
2. Amplifier, to amplify the incoming data
3. Recording Device, to record the voice data

Components
1. Some of the commonly used buttons are play, stop, record, forward and rewind, menu. Some versions can also have some buttons combined, such as play/pause or record/stop.
2. Identify some other components such as microphone, USB, headphone jack, speaker, in your device.
3. The screen will display the recording time left, indicator to show the recording process, location of the data file, battery life, etc.

Process of Recording the Voice

2. After choosing the file location, press the record button and start recording your voice through the microphone.
3. Ensure that the indicator in the display screen of your recorder, indicates the recording process.
4. Now you can go back to the file location and listen to the voice recorded, by pressing the play button.
5. By pressing the forward and rewind keys, you can control the action. You can also increase and decrease the volume by pressing the ‘+’ and ‘-‘ buttons, respectively.

Use Usenet

It was and is still used for file sharing, discussion on various topics, and is still popular among geeks as a forum. Many people don’t know that it is still around and its power can be harnessed to gain specialized data and information.

Using it

Usenet predates Internet technology and has been around since the 1970s. As a resource, it is still quite alive and kicking today, due to its huge amount of content in the form of binary files which can be downloaded quite fast and specialized newsgroups.
It is controlled by a decentralized set of connected servers that host newsgroups and data files. Be it any topic of your interest, it has newsgroups numbering in thousands, catering to it. It is not a peer-to-peer service, but a paid one. Here are some tips on using it for those of you, who want to connect to this enriching source of information.

Select a Service Provider
First and foremost, to use Usenet, you must connect to a service provider, who can grant you access to its resources. For that, you must have a registered account with one of them. Many Internet service providers offer accounts or you may gain access through third-party sources. Most of the service providers charge a monthly or yearly fee for access. The amount depends on the size of bandwidth you demand. The fees are quite nominal and affordable. ‘Giganews’ is one of the most popular service providers.

Get a Software Client
To access Usenet resources through your account, you need to get a special software, often known as a reader. This software connects with the various servers available on the Internet, to grant you access to its resources. These software programs are generally freely downloadable or available as shareware at a minimal cost. This software is analogous to a web browser that is used on the world wide web. Download a software that is compatible with your operating system. There are dedicated clients for each operating system which includes Linux, Windows Vista, and Macintosh.

Install The Reader
The next step is installing this software after downloading it. Make sure that the ‘download location’ that you select has enough storage space as Usenet files can be large.

Configuring the Reader
Once you have subscribed to a service provider, you must configure the reader, according to the user name, password, and server address provided to you by the service. This is an essential step as you cannot access Usenet, without a valid user name and registration.

Search and Subscribe to Various Groups
How can you use the newsgroups? Once you are logged in through the readers, portals of the Usenet world are open to you. You can download a list of group archives now and access a variety of such newsgroups according to your area of interest. The reader allows you to subscribe to any one of these newsgroups. Once you subscribe to any one of them, all the latest posts and developments on it are downloaded automatically to your computer.

Information Infrastructure Design

Information technology (IT) involves the management of information on computer-based information systems. IT deals with the use of computers to store, process, and retrieve information. The construction and design of a safe, reliable, and an always-available information infrastructure is an important constituent of information systems.

Information Infrastructure
It is the collection of communication networks and the software associated with it. It refers to networks and software, which support interaction among people and organizations or the currently available networks and the prospective facilities that they will make available. It includes the Internet, the telecommunication networks, and the embedded systems as also computers. Internet that is regarded as the network of networks is the information infrastructure of today. It is a collection of interconnected computer networks that transmit data in the form of packets using the Internet Protocol. Each of the networks carries information and services like mail and file transfer. World wide web, a collection of documents and other resources, is a service offered by the Internet.Information infrastructure design is concerned with issues like privacy, security, translation, right to information, and most importantly, software and hardware compatibilities. Let us look at each of them.

Privacy: Privacy of information is related to the collection of personal information. Many a time, we are asked to furnish our personal details on the web. It might be in case of an online transaction or in the process of a registration. Such information collected over the web has to be kept private and confidential. People should feel safe while letting out such information. For this purpose, it is important to include information privacy in the design of information infrastructure.

Information Security: Securing information is about protecting it from unauthorized access, disclosure, or modification. An unauthorized access to information should not result in the destruction of that information. Information security deals with confidentiality, availability, and integrity.

Free Information Infrastructure
It is a term used in Europe and it resembles the National Information Infrastructure. The use of the word ‘free’ is intended to focus on freedom and on the internet which is freely accessible. It comprises no software patents. It sometimes refers to open source software. It is about free access, open standards, network neutrality, and less control by state.

Global Information Infrastructure
It is an upcoming communication framework that is meant to connect the computer and telecommunication networks all over the world. Currently, the Internet is considered as the Global Information Infrastructure.
Information infrastructure in IT is actually a vast subject. It deals with the creation, design, and organization of information. It focuses on an infrastructure that caters to the security and access needs of information. In the words of William Pollard, “Information is a source of learning. But unless it is organized, processed, and available to the right people in a format for decision-making, it is a burden, not a benefit.” This briefly describes the goal of an information infrastructure design.
