Voice Over Internet Protocol (VoIP)

Voice over Internet Protocol or Voice over IP or VoIP is a general term for a family of transmission technologies for delivery of voice communications over internet protocol networks such as the internet or other packet-switched networks. Other terms frequently encountered and synonymous with voice over internet protocol are internet protocol telephony, internet telephony, voice over broadband, broadband telephony, and broadband phone. Internet telephony refers to communications services – voice, facsimile, and/or voice-messaging applications – that are transported via the internet, rather than the public switched telephone network. Definition of Voice Over Internet Protocol (VoIP) Voice over internet protocol can be defined as the ability to make telephone calls and to send facsimiles over internet protocol- based data networks with a suitable quality of service and a much superior cost/benefit. Equipment producers see Voice over Internet Protocol (VoIP) as a new opportunity to innovate and compete. The challenge for then Continue reading

Architecture and Key Characteristics of Cloud Computing

Cloud Computing Architecture Cloud computing architecture, the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services and 3-tier architecture. This resembles the Unix philosophy of having multiple programs each doing one thing well and working together over universal interfaces. Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts. The two most significant components of cloud computing architecture are known as the front end and the back end. The front end is the part seen by the client, i.e. the computer user. This includes the client’s network (or computer) and the applications used to access the cloud via a user interface such as a web browser. The back end of the cloud computing architecture is the ‘cloud’ itself, comprising various computers, servers and data storage devices. Continue reading

Reasons for Divergences Between De facto and De jure Exchange Rate Policies

The first reason for the divergences between de facto and de jure exchange rate policies is that, de facto exchange rate stability is just an incidental side effect of a monetary policy strategy in which the exchange rate is only one of the many variables that the central bank monitors and reacts to. This is as; whatever decision of the authorities of the country that is being made in turn will have an effect on the pricing of its goods and services, economic wellbeing of the country and also its exchange rate. The second reason to it is that, the central bank thinks that the economy will occasionally be affected by idiosyncratic shocks that will require significant exchange rate adjustments. This means that the central bank does not want the exchange rate to be tied by a previous commitment that might make the adjustments more difficult to be carried out. Continue reading

Human Resource Management (HRM) – Definitions, Objectives, Scope and Importance

Definitions of Human Resource Management (HRM) Human Resource Management (HRM) is concerned with the “people” dimension in management. Since every organization is made up of people, acquiring their services, developing their skills, motivating them to high level of performance and ensuring that they continue to maintain their commitment to the Organization are essential to achieving organizational objectives. This is true regardless of type of organization – Government, business, education, health, recreation or social action. Those organization that are able to acquire, develop, stimulate and keep outstanding workers will be both effective, able to achieve their goals, and efficient (expanding the least amount of resources necessary). Those organization that are inefficient and ineffective risk the hazards of stagnating or going out of business. According to Thomas G. Spates, Human Resource Management (HRM)  is a code of the ways of organizing and treating individuals at work so that they will get the Continue reading

Data Transmission Modes in Computer Networks

Data communication circuits can be configured in a huge number of arrangements depending on the specifics of the circuit, such as how many stations are on the circuit, type of transmission facility, distance between the stations, how many users at each station and so on. Data communication circuits can however be classified as either two point or multipoint. A two-point configuration involves only two stations, whereas a multipoint configuration involves more than two stations. Regardless of configuration, each station can have one or more computers, computer terminals or workstations. A two point circuit involves the transfer of digital information from a mainframe computer and a personal computer, two mainframe computers, two personal computers or two data communication networks. A multipoint network is generally used to interconnect a single mainframe computer to many personal computers or to interconnect many personal computers. Coming to transmission modes, there are three modes of transmission Continue reading

Case Study: Henry Ford’s Contributions to Organizational Behavior and Leadership

Henry Ford, born in 1863 with his innovative ideas in producing motor vehicles and excellent engineering works went on to become the hero of people in the industry. His primary goal was always to produce petrol propelled motor vehicle and in 1896 he developed his first self propelled vehicle which he called the quadricycle. After a lot of struggles and legal battles, he founded the Ford Motor Company in 1903 with only $28000. He dreamed of making efficient affordable cars and in 1908 produced the popular model T. Henry Ford changed the world with his revolutionary ideas and transformed the motor industry with his leadership. The main aim of this case study is to describe his major contributions to the study of organizational behavior and discuss his leadership style. Every manager or leader’s aim is to achieve a workplace that has a pleasant setting, consists of employees who want to Continue reading
