intel atom processor;

According to the website, the benefits and capabilities of the Intel Atom Processor is:
• A new range of power-efficient devices with excellent performance enabled by industry-leading 45nm high-k metal gate technology and soon, 32nm silicon process technology
• Highly integrated application processor that transforms every day devices
• Smaller, more compact designs with a thermal design power (TDP) ranging from less than 1 watt to 13 watts
• Low power options in select devices enabling incredibly low idle, allowing devices to conserve energy
• Better performance and increased system responsiveness enabled by Intel Hyper-Threading Technology

multitasking;

Like the word suggests, multitasking is doing multiple tasks at once. In terms of processing, multitasking allows the computer to stream through more data streams and programs. A dual core processor boosts the system's multitasking computing power. Dual core processors provide two complete execution cores instead of one. Sicne each core has its own cache, the operating system has sufficient resources to handle intensive tasks in parallel, which provides a noticeable improvement to multitasking.

dual core processor;

A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.

In a single-core processor, the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. The situation is compounded when multi-tasking. In this case, the processor must switch back and forth between two or more sets of data streams and programs - this affects the CPU's performance.

In a dual core processor, each core handles incoming data strings simultaneously - this improves its efficiency and performance.

the cpu;

Central Processing Unit;

The CPU, also known as the microprocessor, is a complete computation engine that is fabricated on a single chip. It is a microchip that serves as the computer's 'brain' and 'heart'. It is this chip that recives data input, processes information and executes instructions.

The name of the first single chip micropressor was Intel 4004. It was introduced to the public in November 1971.

The following is a table of the progression of the CPU from its initial introduction to 2004.

MIPS measures the performance of the CPU according to how many 'millions of instructions per second'.

multimedia service;

The multimedia application that would be hardest to be without is the World Wide Web/Internet. A key advantage of the Internet is the ease of communication. In today's society, individuals

using multimedia;

Multimedia is simply multiple forms of media integrated together. Individual content forms combined in multimedia are: text, audio, still images, animation, video footage and interactivity.

Examples of multimedia application include:
• World Wide Web
• TV (eg. interactive)
• computer games
• virtual reality
• PowerPoint
• Computers
• DVD
• BluRay
• iPods
• mobile phones

nbn;

National Broadband Network;

The NBN will be using a combination of fibre optic technology, fixed wireless and satellite technology (mainly fibre optic). Fibre optic technology converts electric signals carrying data to light and sends the light through narrow transparent glass fibres.

The expected speed of NBN for an average broadband is 100Mbps. The peak speed of NBN is 1Gbps (1024 megabits).

Connections at 25Mbps start at $37.50/month and run up to $84.50/month for 200G of data and a 10Mpbs uplink.

I think that Australia should invest in the NBN. I believe that the NBN will improve the online experience (considering it has a colossal expected speed). Even if the expected cost is quite high, I believe that it will reduce and the NBN will be a good deal.

providers;

The following are Internet Service Provders (ISPs) and the cost for 500GB ADSL2+:
• BigPond - $159
• Optus - $69.99
• TPG - $29.99

Comparing a different plan (50GB Cable):
• BigPond - $49.95
• iiNet - $ 69.95
• Optus - $49.95

fibre optic;

Fibre optic technology converts electrical signals carrying data to light and sends the light through very narrow transparent glass fibres. Fibre optic technology is more expensive than other broadband delivery.

Fibre optics provide extremely high bandwidth - no other cable-based data transmission medium offers the bandwidth that fibre does. It is easy to accomodate increasing bandwidth and it has a resistance to electromagnetic interference 0 it has a very low rate of bit error. It provides a secure transmission medium where cable damages can be detected early and there are secure transmissions.

The installation costs are still very high, despite the prices dropping. Special test equipment is often required - which are additional costs. Fibre optics are susceptible to physical damage since it is a small and compact cable, it can be cut or damaged. The cables can cause wildlife damage - to birds who peck at the fibre cable jackets.

Speed:
Similar to cable modem, fibre optic has speeds of up to 8 Mbps, 9.9 Mbps, 17Mbps and 30Mbps - it exceeds DSL or cable modem speeds.

adsl/dsl;

(Assymetric) Digital Subscriber Line;
DSL broadband service leverages existing copper telephone lines already installed in most businesses and homes to deliver broadband.

ADSL offers independent services where loss of high speed data does not mean you lsoe your telephone service. There is more security so that each subscriber can be configured so that it will not be on the same network. ADSL offers a high bandwidth and has cheap line charges from the phone company.

ADSL broadband can be quite expensive - counting the installation costs. The data rate depends on how far you live from the DSLAM (DSL Access Multiplexer) - which has a lower data rate the further away you are. Because of this, there is limited access with rural areas getting shorted.

Speed:
256kbps/64kbps to 1500kbps/256kbps

cable;

Cable modem broadband service allows cable providers to deliver broadband using coaxial cables which deliver cable TV service to many consumers.

With cable broadband, it has a high-speed connection and data transfer rate - useful for online gaming. Since it is faster, you will spend less time online and get the most value out of your designated usage hours. Also, it does not require a phone line which means that you always have a ready connection, there is no dialing for that connection, there is no dial-up fee and you can stay connected at all times without being cut off by incoming calls.

The speed, however, differs depending on how many people in your area are connected at the same time - so it does not always operate at the highest possible speed. The connection can be expensive and not all areas can access cable Internet. For those who do not use the internet regularly, cable may be a wasted expense.

Speed:
up to 8 Mbps, 9.9 Mbps, 17Mbps and 30Mbps

wireless;

Wireless broadband uses a radio link between the user's location and the service provider's facility. Wireless broadband Internet providers can provide permanent Internet access solutions to customers (often in rural areas) who do not have access to wireline services. This type of wireless broadband access is provided by Wireless Local Area Networks (WLANs) and is often used for public Internet access.

The main advantage of wireless broadband is that you can take your Internet connection anywhere you want. They provide high speed internet access without wires or cable infrastructure. It provides versatility in terms of providing good service not only in lightly populated areas, but also to highly populated aresas. The cost to set up a wireless broadband is cheaper than setting up 'wired broadband'.

The disadvantages of wireless broadband is that it has limited availability, security issues and you would need to have some technical knowledge if you want to set up the wireless network completely.

Speed:
200kbps to 3000kbps (3.0Mbps)

broadband;

The definition of bandwidth ranges according to the context.

In terms of telecommunications, broadband refers to a signaling method that includes or handles a relatively wide range (or band) of frequencies, which may be divided into channels or frequency bins. The definition of bandwidth ranges according to the context.
