Networks

Networking.
Networking is a complex part of computing that makes up the bulk of the IT industry. Without networks, almost all communication in the world would happen. It is because of the creation of networks, TV phone, internet, work, etc..
One way to classify computer networks is in its geographical scope, though many real-world networks interconnect Local Area Networks (LAN) over Wide Area Networks (WAN) and wireless networks [WWAN]. These three (broad) types are:
Local Area Network (LAN)
A local area network is a network of services covering an area relatively small and offers a small number of people. Depending on the number of people using a Local Area Network, a peer-to-peer or client-server method networking can be used. A peer-to-peer is where each client shares their resources with other workstations on the network. Examples of peer-to-peer networks are networks of offices small where resource use is minimal and a home network. A client server network is where each client connects to the server and each other. Client-server networks use servers of different capacities. These can be classified into two types: single-end servers where the server performs a task such as file server, print server, etc, while other servers can not only perform in the capacity of file servers and print servers, but also perform calculations and use these to provide information to customers (Internet / Intranet Server). The computers are connected via Ethernet cable, can be joined, either directly (one computer to another), or through a network hub that allows multiple connections.
Historically, LANs have featured much more WAN high speeds. This is not necessarily the case when the WAN technology appears as Metro Ethernet, implemented over optical transmission systems.
Wide area network (WAN)
A wide area network is a network in a variety of resources are deployed across a large area or internationally. An example this is a multinational business that uses a WAN to interconnect their offices in different countries. The largest and best example of a WAN is the Internet, a network of of many smaller networks. The Internet is considered the largest network in the world. [6]. The PSTN (Public Switched Telephone Network) is also a very large network that is converging to use Internet technologies, although not necessarily through the public Internet.
A wide area network that includes communication through the use of a wide range of different technologies. These technologies include Point-to-Point WANs such as Point-to-Point Protocol (PPP) and High Level Data Link Control (HDLC), Frame Relay, ATM (Asynchronous Transfer Mode) and SONET (Synchronous Optical Network). The difference between the WAN technologies is based on the switching capacity they perform and the speed at which the sending and receiving bits of information (data) occur.
For more information on WANs, see Frame Relay, ATM and SONET.
Wireless networks (WLAN, WWAN)
A wireless network is basically the same as a LAN or WAN, but there are no cables between computers and servers. The data is transferred over sets of radio transceivers. Such networks are beneficial when it is too costly and inconvenient to run the necessary cables. To more information, see Wireless LAN and wireless wide area network. The protocols for access to media for local area networks come from the IEEE.
The most common IEEE 802.11 WLANs cover, depending on antennas, ranges from hundreds of meters to kilometers below. For larger areas, either communications satellites of various types, cellular radio, or wireless local loop (IEEE 802.16) have advantages and disadvantages. Depending on the type of mobility needed standards can come from the IETF or the ITU.

What idea for a magazine you like best?

Idea 1: a composition book http://upload.wikimedia.org/wikipedia/commons/e/e5/Composition_book.jpg idea 2: gel pen magazine with all black pages the magazine would be lined http://www.storepulls.com/products/Black_Board_Basic_Deluxe_Journal-239209-4463.html of poetry and things of that nature

I like the idea of a magazine gel pen ... like putting a little color to the darkness. I do not know. but really miss these things. can do much more with a composition i guess. but the magazine finally gel pen.
