IP Address - In the most widely installed level of the Internet Protocol (Internet Protocol) today, an IP address is a 32-binary digit number that identi- fies each sender or receiver of information that is sent in packet across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to. At the other end, the recipient can see the IP address of the Web page requestor or the e-mail sender and can respond by sending another message using the IP address it received.

IPCONIFG - A utility that provides for querying, defining and managing IP addresses within a network. A commonly used utility, under Windows NT and 2000, for configuring networks with static IP addresses.

ISP - An ISP (Internet service provider) is a company that provides individuals and companies access to the Internet and other related services such as Web site building and virtual hosting.

LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building).

MAC Address - The MAC (Media Access Control) address is a unique num- ber assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level.

mIRC - mIRC runs under Windows and provides a graphical interface for log- ging onto IRC servers and listing, joining and leaving channels.

Network Mask - also known as the “Subnet Mask”.

PCMCIA - The PCMCIA (Personal Computer Memory Card International Association) is an industry group organized in 1989 to promote standards for a credit card-size memory or I/O device that would fit into a personal computer, usually a notebook or laptop computer.

Ping - (Packet INternet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by send- ing out a packet and waiting for a response.

Wireless Network Access Point

RJ-45- A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices.

Roaming - The ability to use a wireless device and be able to move from one access point’s range to another without losing the connection.

Static IP Address - A permanent IP address that is assigned to a node in a TCP/IP network.

Subnet Mask - The method used for splitting IP networks into a series of sub- groups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets.

TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (Internet Protocol) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packet) that a message is divided into for efficient routing through the Internet.

TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your comput- er is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

UDP (User Datagram Protocol) - A communications method (protocol) that offers a limited amount of service when messages are exchanged between com- puters in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one com- puter to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP.

WAP11 specifications

The Linksys WAP11 is a versatile and influential device in the realm of wireless networking. Released in the early 2000s, this wireless access point was designed to offer seamless connectivity for users who required reliable internet access without the constraints of wired connections. The WAP11 quickly became popular for home and office environments, allowing multiple devices to connect to the internet wirelessly.

One of the standout features of the Linksys WAP11 is its compliance with the IEEE 802.11b wireless networking standard. This standard enabled the WAP11 to deliver a maximum data transfer rate of up to 11 Mbps, which was impressive at the time of its launch. It also supported backward compatibility with 802.11g devices, enabling a broader range of connectivity options for users.

The WAP11 utilizes both infrastructure and ad-hoc modes, catering to various networking setups. The infrastructure mode allows for connection through a wireless router or switch, while the ad-hoc mode facilitates a peer-to-peer connection among multiple devices. This flexibility makes the WAP11 suitable for both small home networks and larger office settings.

Another notable characteristic of the WAP11 is its range and coverage capability. The device operates on the 2.4 GHz frequency and is designed to provide coverage in a typical home or small office. When deployed in an environment with minimal obstacles, the WAP11 offers a considerable range, ensuring that users can connect from various locations within the premises.

Security features are also a significant aspect of the WAP11. It supports Wired Equivalent Privacy (WEP) encryption, providing a basic level of security to protect data transmitted across the wireless network. While WEP has since been superseded by more robust security protocols like WPA and WPA2, it was a necessary feature for its time, giving users peace of mind regarding their data protection.

Installation and setup of the Linksys WAP11 are user-friendly, making it accessible even for individuals with minimal technical experience. The device comes with a web-based interface that allows users to configure settings, adjust security parameters, and troubleshoot network issues with ease.

In summary, the Linksys WAP11 is a remarkable wireless access point that laid the groundwork for the wireless networking standards we now take for granted. With its support for 802.11b, flexible operating modes, decent range, and user-friendly configuration, the WAP11 provided a reliable solution for expanding wireless connectivity. Its influence can be seen in the ongoing evolution of wireless networking technologies, emphasizing the importance of connectivity in our increasingly digital world.
