Answer 1). Many IT managers focus solely on mastering new tech skills to increase their value to their employers -- a strategy that makes perfect sense, but only up to a point. Once a manager reaches that point, he is viewed as only technically proficient and being perceived as unskilled in business planning and learning how to communicate and collaborate well with customers, coworkers, and service providers. Having a balance of these "hard" technology skills and "soft" business and people skills

overlap. Few people thoroughly understand where data goes as it is switched through the "cloud." What is important is that data goes in, travels through the line, and arrives at its destination. | Central Office (CO) | The central office is a switching facility connected to the WAN, and is the nearest point of presence for the WAN provider. It provides WAN-cloud entry and exit points. | Local loop | The local loop is the cable that extends from the central office to the customer location. The

ABSTRACT In the context of the rapid growth of mobile computing penetration in developing countries, mobile telephony is currently considered to be particularly important for such development. Yet, until recently, very little systematic evidence was available that shed light on the developmental impacts of mobile computing. The objective of this paper is to evaluate the problems and prospects of mobile computing in Nigeria. The paper will be analyzed by theme in order to provide a thematic overview

transfer an n-byte file along a path composed of the source, destination, seven point-to-point links, and five switches. Suppose each link has a propagation delay of 2us, bandwidth of 4Mbps, and that the switches support both circuit and packet switching. Thus you can either break the file up into 1-kB packets, or set-up a circuit through the switches and send the file as one contiguous bit stream. Suppose that packets have 24 bytes of packet header information and 1000 bytes of payload, that store-and-forward

Packet Switching The concept of packet switching was first developed in the early 1960s, by researchers at the Massachusetts Institute of Technology. Packet switching is the dividing of messages into packets before they are sent, transmitting each packet individually, and then reassembling them into the original message once all of them have arrived at the intended destination. Packets are the fundamental unit of information transport in all modern computer networks, and increasingly in other
