the new 4G dongle that will be available in mid 2010

4G networks, released in April this year has been thought to be able to reach speeds of up to 100mb p/s, 10 times quicker than the fastest 3G speed available today. Despite the launch of the network, at the moment there are no handsets on the market that supports 4G. Stockholm in Sweden and Oslo in Norway will be the first places on Earth to test the network out, the telephone company Telia Sonera have asked customers to test out the network in the early part of this year. 4G uses Long Term Evolution Technology (LTE).

Pro’s : access to faster broadband wherever you are.

Cons: people have to spend more money to buy it!

the difference of components inside and ouside a laptop. so what different? well all components inside a laptop are smaller, they have to be, to make a laptop as portable and as compact as possible for example, below there are two pictures, the one on the left being a laptop motherboard, and the one on the right, a PC motherboard.

this is smaller than a normal desktop motherboard.

Most laptop components are designed differently to internal desktop components.

this is larger than a laptop motherboard becasue there is more room in its base unit.

Laptop processors are designed to use less power and create less heat, therefore if laptop processors create less heat, they will not need the huge cooling devices (fans) to  keep the internal components cool, however if they were needed, it would make the laptop less portable and would also make the laptop heavier.

its my first post people!!
