Access point - The access point is an external device which is used for linking a wireless network to a wired LAN. Effectively it increases the range of wireless network and also provides additional network management and security features. PCI Adapter - To get wireless connectivity for a desktop computer an external module called PCI wireless adapter card can be plugged in to the empty slot. Router – A router is a device used for sharing a single Internet connection across multiple computers. This is ideal in the home or office where
Basically, ATMare connect to host computer and host computer is connected to the bank computer (refer to diagram 5). Host computer are being a third party to maintain all their facilities and equipment. In this cases, internet service provider (ISP) is take part in this embedded system because ISP is used by ATM to communicate between host processors. After user input their detail, the information will passed to the host processor by the ATM. After that, the host processor will checks all the user details with authorized bank.
The address of the destination shows the user where the data frame is going. The following six bytes are what is called the source address and it holds information that tells us where the data frame has come from. A MAC address can be UA meaning universally administered to a device or LA meaning
Visa, Discover, and American Express. The other aspect of co-branded card portrays a different picture. Here, co-branded credit cards can also be the cards which are partnered up with multiple merchants and they can be used for making payments and getting cashback and reward points from a variety of merchants. What is a Branded Card: Each debit or credit card is branded
A wireless LAN radio NIC, also known as radio card, often implements the 802.11 standard. The cards implement one physical layer, such as 802.11a or 802.11b/g. As a result, the radio card must apply a compatible version of the standard to the wireless LAN. Radio cards come in a variety of form factors that include PCI, ISA, PC card, mini-PCI, and CF. PC normally utilize ISA and PCI cards; but for laptops, it use PC cards, mini-PCI, and CF
• 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).
The diagram shows a cluster with two nodes which are connected or interconnected all together by the means of a high-speed link which are use to exchange messages or data in other to manage the activities of the cluster. These links between the nodes can be shared using LAN with the help of other computers, which are not use as part of the cluster (Stallings 2013:655). Also showed in the diagram in the configuration of b, there is a disk use to connect to multiple computers in the cluster and there is a high-speed link of interconnection of the clusters. RAID is the name of the disk used. This type of disk is used when if there is a failed node, it does not conciliation the whole system.
Here network topology consists of three nodes: a fixed host, a base station and the mobile host, and evaluated throughput, packet delay and transfer time. TCP Reno shows high throughput, least transfer time and less packet delay than
