to and from the central node) plus any delay generated in the centralnode. An active star network has an active central node that usually has the means to prevent echo-related problems. Components to Operate The Star Network Topology (HUB, Switch, & Router) HUB Hub is digital cable and satellite television channel. In star topology, each computer isconnected to a central hub using a point-to-point connection. The central hub can be acomputer server that manages the network, or it can be a much simpler device that onlymakes the connections between computers over the network possible.
2.1 Wireless LAN Infrastructure Devices Proper WLAN infrastructure design requires understanding and deploying QoS (Quality of Service) on the wireless network to ensure end-to-end data / video/voice quality on the entire network. Like a traditional wired LAN, WLAN is a grouping of computers and peripheral devices that share a common communications backbone. As per the name itself, a WLAN allows users to connect to the LAN through radio transmission. The below mentioned are the most common components of a WLAN. Access point - The access point is an external device which is used for linking a wireless network to a wired LAN.
This saves time for the user, reduces communication costs, and decentralizes network structure. Distributed computing interacts with different computers through a network. The latency and network traffic of interactions often seriously affect the quality and coordination of two programs running on different computers. If one of the programs is a mobile agent, it can migrate to the computer the other is running on communicate with it locally. That is, mobile agent technology enables remote communications to operate as local
In IP networking, the router maintains both a LAN address and a WAN address. The Transmission Control Protocol (TCP) It is one of the core protocols of the Internet protocol suite (IP), and is so common that the entire suite is often called TCP/IP. TCP provides reliable, ordered and error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer. HTTP, HTTPS, SMTP, POP3, IMAP, SSH, FTP, Telnet and a variety of other protocols are typically encapsulated in TCP.
To attach a device to a network, connect to the adapter machine and connect it to any port on any other adapter. AppleTalk broadcasts a network address number operated by internal protocols and automatically distributes the computer's readable name, and records the names and other types of other machines in the network so the user can navigate the devices. If you have more than one daughter in the same room through a GuI-based selector, AppleTalk is very easy to use those ad-hocked networks. Apple will use an advertisement that shows a network created from two seats in an
• MAC Address :- A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model. MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the card 's read-only memory or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer 's registered identification number and may be referred to as the burned-in address (BIA).
A network is a group of two or more computer systems linked together. A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices pass data to each other along network links for data connections. The connections between nodes are established using either cable media or wireless media. Network computer devices that originate, route and terminate the data are called network nodes.
Regional offices will communicate with head office through modern communication systems such as electronic mail (e-mail), video conferencing, voice over internet protocol (VoIP), instant messaging and groupware also known as workflows. These systems enable users in different regions to exchange data seamlessly without being hindered by physical boundaries. Communication systems use hardware and software to send and receive information between computers linkedthrough local area networks (LANs) or wide area networks (WANs) such as the internet. These networks are usually limited to a single building or sites located in different geographical areas, respectively (Boonstra, Boddy and Kennedy,
A network is any collection of independent computers that communicate with one another over a shared network medium. It can also define as a collection of two or more connected computers. Once these computers are linked in a network, persons can share files and

INTRODUCTION A wireless network is open data communications system, which uses wireless media such as radio frequency technology to transmit and receive data over the air, minimizing the need for wired connections. Wireless networks are used to augment rather than replace wired networks and are most commonly used to provide last few stages of
