Computer Network – Comprehensive View – Part 1
Oct 23rd
Wireless networks enable people to communicate, access to applications and information without wires. That means access to the freedom of movement and the ability to expand the applications in different areas of the building, or near the city anywhere in the world. People, for example, while in the house search in the Internet, they can search in quiet places away from the noise of children or the rioters in front of the television presence of the entire family. Wireless networks allow people to interact with e-mail or surf the Internet from anywhere they like.
Wireless networks exist around us for many years, in fact, is the early forms of radio communications by the use of Native American Leather Ox for radio contact by putting it on the fire and remove it in waves for sending smoke signals to the other over great distances. Also the use of light pulses carrying information between the ships by Morse code which still form important contacts.
kind of cellular telecommunications is common today for talks with some people across the world.
Introduction to concepts:
Wireless networks play a crucial role in people’s lives, whether at home or at work or in public areas. The objective is simple networks to provide wireless communication between users and information sources without the use of wires. It is necessary to address the basic concepts of wireless networks by understanding how to operate. This chapter provides a full definition of wireless networks and how users use them in a variety of applications.
wireless communications systems are for many but the characteristic feature of wireless networks, said it was investigating the communication between the computers, these devices include a Personal Digital Assistant (PDA) Personal Digital Assistant and laptops and PCs

Wireless networks located in multiple categories, depending on the size of the physical area that can be covered by network.
The following types of wireless network meet the needs of multiple users:
* Wireless personal – Area network (PAN).
* Wireless Local Area network (LAN).
* Wireless Metropolitan-Area network (MAN).
* Wireless Wide – Area network (MAN).
This is using the expansion all major cables for wired networks (such as LAN or WAN) used for years before it enters the wireless network.
Each type of wireless network has the advantages of complementary meet multiple requirements. The following paragraphs explore each type of wireless networks in a concise manner.
Wireless networks (PANS):
The area of wireless networks is a relatively short (up to 50 feet) and most of their effectiveness to meet the needs of a small room or in the cargo area.
PANS networks is the performance of the average of data rate of up to (2MBPS). Imperatives followed these advantages for the replacement of cables in many cases.
PAN wireless network includes a person synchronize personal PDA with his laptop computer or personal computer. In a similar, PAN wireless network can provide radio communication to the printer. The advantage of the abolition of knots in the wire when using this type of computer is very useful, where the initial installation of the equipment is easy.
Wireless networks (LANS):
Networks wireless LANs provide high performance within and around office buildings and labs, and homes often have the users in these areas laptop computers, personal computers, PDA screens and processors to support large applications.
LANS meet the requirements of communication for these types of computers effectively.
