[description], Story, any other text you want to use. Setting Up a Network -- Wired or Wireless? by: Deryck Richards
To Wire or Not to Wire Wireless networks are en vogue, but your installation won't be successful unless you chose the right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone. If the computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even across the street. Aside from the obvious benefit of not having wires, wireless networks are more convenient since the setup, configuration, and reconfiguration can often be done within minutes, without extensive planning. Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one. Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you don't have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to access the network, or do both. Do It Yourself or Call a Professional? If you decide to use a wired network, consider whether you will install it yourself or hire a professional. If you have a small number of computers that are all situated very close to one another, you may be able to buy pre-assembled network cables and connect them yourself. If you need to wire multiple floors and lay wire through ceilings and walls, you need a professional installation. If you go this route, it is best to begin with a floor plan of your office or home, determine what your current needs are, and consider how the network design can be adapted to future needs. A professional installer should be familiar with EIA/TIA standards, local wiring and electrical codes, and making custom cables. Network cabling professionals are often judged by the neatness of their work, because sloppy cabling is more apt to deteriorate over time, harder to manage, and poses more of a fire risk. Having a wireless network or a wired network is not mutually exclusive. Many small offices have a wired network in addition to one or more wireless networks, depending on their needs. Wireless networks are continuing to get faster, more secure, and less expensive. Wired networks will continue to coexist with wireless networks, often in the same homes and offices.
rep
Netscape Corporation has created the best known secure server technologies. It uses a security protocol called Secure Sockets Layer (SSL) that provides data encryption, server authentication, message integrity and optional client authentication for a TCP/IP connection. When a client seeking to purchase rep connects with a secure server, they exchange a *handshake* which initiates a secure session. With this protocol, the same server system can run both secure and unsecured web servers simultaneously. This means an rep organization or company can provide some information to all users using no security, and other information that is secured. For example, a business that sells rep online can have its storefront (merchandise catalog) unsecured, but ordering and payment forms can be secure. Why are these developments important? As the Internet becomes a way to buy and sell rep products and services, financial transactions become essential. Right now, most rep transactions involve the exchange of credit card information, either directly over the network, or by phone, to complete a transaction initiated online. Eventually, you will be able to use cash as well as credit, directly over the network. There are two basic kinds of digital cash, anonymous cash and identified cash. Anonymous cash is just like paying for rep with paper cash but it also carries no information about the person making the transaction, and leaves no transaction trail. You create it by using numbered bank accounts and blind signatures. Identified cash, on the other hand, contains information revealing the identity of the person who withdrew it from the bank. Like credit card transactions, identified cash can be tracked as it moves through the system and involves fully identified accounts and non-blind signatures. Whether you use digital cash when purchasing rep is entirely up to you. We suggest you employ the purchasing avenues available from the rep supplier we recommend.
