It offers transmissions speeds at up to 54 Mbps in the 2.4-GHz band. A Access point It is the hardware interface between a wireless LAN and a wired LAN. The access point attaches to the wired LAN through an Ethernet connection. Applet Applets are small Java programs that can be embedded in an HTML page. The rule at the moment is that an applet can only make an Internet connection to the computer form that the applet was sent. ASCII American Standard Code For Information Interchange, it is the standard method for encoding characters as 8-bit sequences of binary numbers, allowing a maximum of 256 characters. ARP Address Resolution Protocol. ARP is a protocol that resides at the TCP/IP Internet layer that delivers data on the same network by tran slating an IP address to a physical address. AVI Audio Video Interleave, it is a Windows platform audio and video file type, a common format for small movies and videos. B BOOTP Bootstrap Protocol is an Internet protocol that can automatically configure a ne twork device in a diskless workstation to give its own IP address. C Communication Communication has four components: sender, receiver, message, and medium. In networks, devices and application tasks and processes communicate messages to each other over media. They represent the sender and receivers. The data they send is the message. The cabling or transmission method they use is the medium. Connection In networking, two devices establish a connection to communicate with each other. D DHCP Dynamic Host Configuration Protocol was developed by Microsoft a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can ev en change while it is still connected. DHCP also suppor ts a mix of static and dynamic IP addresses. This simplifies the task for network administrators because the software keeps track of IP addresses ra ther than requiring an administrator to manage the task. This means a new computer can be added to a network without the hassle of manually assigning it a unique IP address. DHCP allows the specification for the service provided by a router, gateway, or other network device that automatically assigns an IP address to any device that requests one DNS Domain Name System is an Internet service that translates domain names in to IP addresses. Since domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses every time you us e a domain name the DNS will translate the name into the corresponding IP address. For example, the domain name www.network_camera.com might translate to 18.104.22.168. E Enterprise network An enterprise network consists of collections of networks connected to each other over a geographically dispersed area. The enterprise network serves the needs of a widely distributed company and operates the company’s mission-critical applications. Ethernet The most popular LAN communication technology. There are a variety of types of Ethernet, including 10 Mbps (traditional Ethernet), 100 Mbps (Fast Ethernet), and 1,000 Mbps (Gigabit Ethernet). Most Ethernet networks use Category 5 cabling to carry information, in the form of electrical signals, between devices. Ethernet is an implementation of CSMA/CD that operates in a bus or star topology. F Fast Ethernet Fast Ethernet, also called 100BASE-T, operates at 10 or 100Mbps per second over UTP, STP, or fiber-optic media. Firewall Firewall is considered the first line of defense in protecting private information. For better security, data can be encrypted. A system designed to prevent unauthorized access to or from a private network. Firewalls are frequently used to prevent unauthorized Internet users from acce ssing private networks connected to the Internet, especially Intranets all messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria. G Gateway A gateway links computers that use different data formats together. Group Groups consist of several user machines that have similar characteristics such as being in the same department. H HEX Short for hexadecimal refers to the base-16 number system, which consists of 16 unique symbols: the numbers 0 to 9 and the letters A to F. For example, the decimal number 15 is represented as F in the hexadecimal numbering system. The hexadecimal system is useful because it can represent every byte (8 bits) as two consecutive hexadecimal digits. It is easier for humans to read hexadecimal numbers than binary numbers. I IEEE Institute of Electrical and Electronic Engineers. Intranet This is a private network, inside an organization or company, that uses the same software you will find on the public Internet. The only difference is that an Intranet is used for internal usage only. Internet The Internet is a globally linked system of computers that are logically connected based on the Internet Protocol (IP). The Internet provides different ways to access private and public information worldwide. Internet address To participate in Internet communications and on Internet Protocolbased networks, a node must have an Internet address that identifies it to the other nodes. All Internet addresses are IP addresses IP Internet Protocol is the standard that describes the layout of the basic unit of information on the Internet (the packet) and also details the numerical addressing format used to route the in formation. Your Internet service provider controls the IP address of any device it connects to the Internet. The IP addresses in your network must conform to IP addressing rules. In smaller LANs, most people will allow the DHCP function of a router or gateway to assign the IP addresses on internal networks. IP address IP address is a 32- binary digit number that identifies each sender or receiver of information that is sent in packets across the Internet. For example 22.214.171.124 is an IP address, it is the clos et thing the Internet has to telephone numbers. When you “call” that number, using any connection methods, you get connected to the computer that “owns” that IP address. ISP Internet Service Provider, is a company that maintains a network that is linked to the Internet by way of a dedicated communication line. An ISP offers the use of its dedicated communication lines to companies or individuals who can’t afford the high monthly cost for a direct connection. J JAVA Java is a programming language that is specially designed for writing programs that can be safely downloaded to your computer through the Internet without the fear of viruses. It is an object-oriented multithread programming best for creating applets and applications for the Inte rnet, Intranet and other complex, distributed network. L LAN Local Area Network a computer network that spans a relatively small area sharing common resources. Most LANs are confined to a single building or group of buildings. N NAT Network Address Translator generally applied by a router, that makes many different IP addresses on an internal network appear to the Internet as a single address. For routing messages properly within your network, each device requires a unique IP address. But the addresses may not be valid outside your network. NAT solves the problem. When devices within your network request information from the Internet, the requests are forwarded to the Internet under the router's IP address. NAT distributes the responses to the proper IP addresses within your network. Network A network consists of a collection of two or more devices, people, or components that communicate with each other over physical or virtual media. The most common types of network are: LAN – (local area network): Computers are in close distance to one another. They are usually in the same office space, room, or building. WAN – (wide area network): The computers are in different geographic locations and are connected by telephone lines or radio waves. NWay Protocol A network protocol that can automatically negotiate the highest possible transmission speed between two devices. P PING Packet Internet Groper, a utility used to determine whether a specific IP address is accessible. It functions by sending a packet to the specified address and waits for a reply. It is primarily used to troubleshoot Internet connections. PPPoE Point-to-Point Protocol over Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as DSL or cable modem. All the users over the Ethernet share a common connection. Protocol Communication on the network is governed by sets of rules called protocols. Protocols provide the guidelines devices use to communicate with each other, and thus they have different functions. Some protocols are responsible for formatting and presenting and presenting data that will be transferred from file server memory to the file server’s net work adapter. Others are responsible for filtering information between networks and forwarding data to its destination. Still other protocols dictate how data is transferred across the medium, and how servers respond to workstation requests and vice versa. Common network protocols responsible for the presentation and formatting of data for a network operating syst em are the Internetwork Packet Exchange (IPX) protocol or the Internet Protocol (IP). Protocols that dictate the format of data for transferors the medium include token- passing and Carrier Sense Multiple Access with Collision Detection (CSMA/CD),implemented as token-ring, ARCNET, FDDI, or Ethernet. The Router Information Protocol (RIP),a part of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, forwards packets from one network to another using the same network protocol. R RARP Reverse Address Resolution Protocol, a TCP/IP protocol that allows a phys ical address, such as an Ethernet address, to be translated into an IP address. RJ-45 RJ-45 connector is used for Ethernet cable connections. Router A router is the network software or hardware entity charged with routing packets between networks. S Server It is a simple computer that provides resources, such as files or other information. SMTP The Simple Mail Transfer Protocol is used for Internet mail. SNMP Simple Network Management Protocol. SNMP was designed to provide a common foundation for managing network devices. Station In LANs, a station consists of a device that can communicate data on the network. In FDDI, a station includes both physical nodes and addressable logical devices. Workstations, sing le-attach stations, dualattach stations, and concentrators are FDDI stations. Subnet mask subnetmask. In TCP/IP, the bits used to create the subnet are called the T (TCP/IP) Transmission Control Protocol/Internet Protocol is a widely used transport protocol that connects diverse computers of various transmission methods. It was developed by the Department of Defense to connect different computer types and led to the development of the Internet. Transceiver A transceiver joins two network segments together. Transceivers can also be us ed to join a segment that uses one medium to a segment that uses a different medium. On a 10BASE-5 network, the transceiver connects the network adapter or other network device to the medium. Transceivers also can be used on 10BASE-2 or 10BASE-T networks to attach devices with AUI ports. U UDP The User Datagram Protocol is a connectionless protocol that resides above IP in the TCP/IP suite. ULP The upper-layer protocol refers to Application Layer protocols such as FTP,SNMP, and SMTP. User Name The USERNAME is the unique name assigned to each person who has access to the LAN. Utility It is a program that performs a specific task. UTP Unshielded twisted-pair. UTP is a form of cable used by all access methods. It consists of several pairs of wires enclosed in an unshielded sheath. W WAN Wide-Area Network. A wide-area network consists of groups of interconnected computers that are separated by a wide distance and communicate with each other via common carrier telecommunication techniques. Windows Windows is a graphical user interface for workstations that use DOS. Workgroup A workgroup is a group of users who are physically located together and connected to the same LAN, or a group of users who are scattered throughout an organization but are logica lly connected by work and are connected to the same network group. Workstations Workstation refers to the intelligent computer on the user’s desktop. This computer may be an Intel- based PC, a Macintosh, or a UNIXbased workstation. The workstation is any intelligent device a user works from.
