What is peer2peer?

Peere2peer is where the files are stored on and served by personal computers of the users. Most people who engage in file sharing are also downloading files that other users share. Sometimes these two activities are linked together. P2P file sharing is distinct from file trading in that downloading files from a P2P network does not require uploading, although some networks either provide incentives for uploading such as credits or force the sharing of files being currently downloaded A peer-to-peer (or P2P) computer network relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes. Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology. A pure peer-to-peer network does not have the notion of clients or servers, but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network. This model of network arrangement differs from the client-server model where communication is usually to and from a central server. A typical example for a non peer-to-peer file transfer is an FTP server where the client and server programs are quite distinct, and the clients initiate the download/uploads and the servers react to and satisfy these requests

What layer of Windows 200 and XP is most responsible for interacting with hardware?

HAL (Hardware Abstraction Layer). Limiting access to hardware mainly to the HAL increases OS integrity because more control is possible. With this isolation, an application cannot cause a system to hang by making illegal demands on hardware. (Source: CompTIA A+ Guide to Software Managing, Maintaining, and Troubleshooting.

Why do you have computer keyboards?

The QWERTY layout was created in the early 1870s by Christopher Sholes, a Milwaukee newspaper editor and printer, who, with the help of his friends Carlos Glidden and Samuel Soule, built an early typewriter and filed a patent for it in 1867.

The first model used a piano like keyboard with 2 rows of keys arranged in alphabetical order like this:

3 5 7 9 N O P Q R S T U V W X Y Z

2 4 6 8 . A B C D E F G H I J K L M

However, it had 2 problems - 1: the keys were mounted on metal arms, which would clash and jam if neighboring arms were pressed simultaneously or one after the other, and 2: the user had to open the paper carriage to fix the jam.

Sholes tried to perfect the invention over the next 6 years, and eventually came up with a layout similar to the modern QWERTY:

2 3 4 5 6 7 8 9 - ,

Q W E . T Y I U O P

Z S D F G H J K L M

A X & C V B N ? ; R

Shole's backer, James Densmore, sold manufacturing rights to E. Remington and Sons, who modified it further. The layout became popular with the Remington No. 2 typewriter, the first one to include a shift key for both upper and lower case letters, and later with the advent of personal computers.

Part of the reason why the QWERTY layout works is also because the letters are arranged in diagonal columns. The idea that the QWERTY layout is meant to slow typists down is incorrect - it's instead meant to prevent jams when the typist is typing rapidly.

How does mobile internet work?

The mobile node is the device that provides Internet mobility. The home agent is the router that communicates with the mobile node. A foreign agent is another router that the mobile node accesses in a foreign network. In each network there are correspondent nodes (mobile Internet servers hosting the mobile website). The job of the foreign node is to tag a temporary Internet address on to the mobile node. The home IP address is sent to the mobile node in small packets of data through the air via radio frequency towers. The home agent and foreign network constantly broadcast the network service. The mobile node registers a new IP address in response to the signals received from the home agent.

First off, make sure your speakers are plugged into the right socket. Check that the speaker plug goes into the GREEN OUTPUT socket. After that, check to see if you have the latest drivers for your sound card or onboard sound. Finally, make sure that these drivers are in effect at all times. That, or your speakers are broken.
