Data Encryption Standard In 1972‚ the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security‚ a subject then in its infancy. One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data during transmission and in storage. Prior to this NBS initiative‚ encryption had been largely the concern of military and intelligence organizations. The encryption algorithms‚ i.e.‚ the

Characteristics and quality of data transmission – Dependent on characteristics of medium and signal – Guided medium ∗ Medium is more important in setting transmission parameters – Unguided medium ∗ Bandwidth of the signal produced by transmitting antenna is important in setting transmission parameters ∗ Signal directionality · Lower frequency signals are omnidirectional · Higher frequency signals can be focused in a directional beam • Design of data transmission system – Concerned with data rate and distance

1. PRIMARY ANDSECONDARY DATA We explore the availability and use of data (primary and secondary) in the field of business research.Specifically‚ we examine an international sample of doctoral dissertations since 1998‚ categorizingresearch topics‚ data collection‚ and availability of data. Findings suggest that use of only primarydata pervades the discipline‚ despite strong methodological reasons to augment with secondary data. INTRODUCTION Data can be defined as the quantitative or qualitative

serious macroeconomic imbalances - including multiple official exchange rates that overvalue the Burmese kyat‚ fiscal deficits‚ lack of commercial credit further distorted by a non-market interest rate regime‚ unpredictable inflation‚ unreliable economic data‚ and an inability to reconcile national accounts. Myanmar’s poor investment climate - including weak rule of law - hampers the inflow of foreign investment; in recent years‚ foreign investors have shied away from nearly every sector except for natural
