More Internet-enabled phones will be sold and activated in 2009 than personal computers.

Today, the computer for the rest of us is a phone.

Our infrastructure has to keep up with this growth just to maintain our current level of quality, but to actually make search smarter, our index and infrastructure need to grow at a pace FASTER than the web.

A network is simply a collection of computers or similar devices that can communicate over a transmission medium.

To actually send any data from one computer to another we need to make use of a network protocol. A network protocol is a set of common rules that defines how data should be sent.

Without a common suite like TCP/IP, the internet would not be possible.

This alignment is important because well-designed learning spaces and enabling technologies encourage students to spend more time on campus, increasing engagement and improving retention.

They appear to prefer learning-by-doing rather than learning-by-listening and often choose to study in groups. Much to the consternation of adults acculturated to lectures, they become impatient in situations where they don't feel engaged.

While many student attributes may be important to educators, five characteristics seem particularly applicable for learning spaces: Digital Mobile Independent Social Participatory

parents should consider monitoring the amount of time spent on-line.

Some computer-sex offenders have even obtained toll-free 800 numbers, so that their potential victims can call them without their parents finding out.

The upper layers of the OSI model deal with application issues and generally are implemented only in software. The highest layer, the application layer, is closest to the end user. Both users and application layer processes interact with software applications that contain a communications component. The term upper layer is sometimes used to refer to any layer above another layer in the OSI model. The lower layers of the OSI model handle data transport issues. The physical layer and the data link layer are implemented in hardware and software. The lowest layer, the physical layer, is closest to the physical network medium (the network cabling, for example) and is responsible for actually placing information on the medium.

Internetwork addresses identify devices separately or as members of a group. Addressing schemes vary depending on the protocol family and the OSI layer. Three types of internetwork addresses are commonly used: data link layer addresses, Media Access Control (MAC) addresses, and network layer addresses.

A data link layer address uniquely identifies each physical network connection of a network device. Data-link addresses sometimes are referred to as physical or hardware addresses.

put the relative threat of online predators in perspective, while at the same time noting that schools and parents must to more to give students the media literacy skills required to use the Internet responsibly.

On the other side of this digital divide, there are countless young people who feel like they are masters of digital technology, despite the fact they often use these tools naively or recklessly because of a lack media literacy and critical thinking skills.

ore than a decade ago, schools began investing heavily in laptops at the urging of school boards and parent groups who saw them as the key to the 21st century classroom. Following Maine’s lead in 2002, states including Michigan, Pennsylvania and South Dakota helped buy laptops for thousands of students through statewide initiatives like “Classrooms for the Future

Classrooms for the Future

Many school administrators and teachers say laptops in the classroom have motivated even reluctant students to learn, resulting in higher attendance and lower detention and dropout rates.
