1. How does multipoint circuit differ from a point-to-point circuit? Multipoint is also called a shared circuit. In this configuration, many computers are connected on the same circuit. This means that each must share the circuit with the others, much like a party line in telephone communication. The disadvantage is that only one computer can use the circuit at a time. When computer is sending or receiving data, all others must wait. The advantage of multipoint circuits is that they reduce the amount of cable required and typically use the available communication circuit more efficiently. Multipoint configurations are cheaper than point-to-point configurations. Point-to-point configuration is so named because it goes from one point to another (e.g., one computer to another). These are also called as dedicated circuits because they are dedicated to the use of these two computers. This type of configuration is used when the computers generate enough data to fill the capacity of the communication circuit. This can get very expensive, particularly if there is some distance between the computers.

2. Describe the three types of data flows. Circuits can be designed to permit data to flow in one direction or in both directions. There are three ways to transmit: simplex, half-duplex, and full duplex. Simplex is one-way transmission, such as that with radios and TVs. Half-duplex communication link is similar to a walkie-talkie; only one computer can transmit at a time. With full-duplex transmission, you can transmit in both directions simultaneously, with no turnaround time.

...Nt1110 Unit 6 Research Paper Nas * What is an NAS devise? A Network Attached Storage device is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role. * What is the speed of the network adapter available on a NAS device? There are many varieties of NAS devices, depending on if you build it yourself or purchase it. The speed is usually 1GB Ethernet connection but it can be changed to multiple Gb, 10Gb, fiber optic by adding a PCIe network card(s). * What is the capacity range? The capacity range also varies. With a port replication and add on hardware drive controller cards there really isn’t a limit on size. A board that has six SATA ports can be replicated allowing for thirty drives to be attached, if 3TB drives are used in RAID 50,that would be 72TB of storage. * Is there any fault tolerance (such as RAID) built into a NAS device? If set up correctly RAID 50 is fairly stable, RAID 10 has been touted as on of the best set ups because more drives can fail at one time with having data loss. * Are management features available?

...13 Agent-Oriented Novel Quantum Key Distribution Protocol for the Security in Wireless Network Xu Huang, Shirantha Wijesekera and Dharmendra Sharma University of Canberra Australia 1. Introduction Wireless security is becoming increasingly important as wireless applications and systems are widely adopted. Numerous organizations have already installed or are busy in installing “wireless local area networks” (WLANs). These networks, based on the IEEE 802.11 standard, are very easy to deploy and inexpensive. Wi-Fi allows LANs to be deployed without cabling for client devices, typically reducing the costs of network deployment and expansion. As of 2007 wireless network adapters are built into most modern laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in ever more devices. Wi-Fi has become widespread in corporate infrastructures, which also helps with the deployment of RFID technology that can piggyback on Wi-Fi. WiFi is a global set of standards, unlike mobile telephones, any standard Wi-Fi device will work anywhere in the world. Other important trends in wireless adoptions are including the introduction of wireless email with devices such as the Blackberry and The Palm VII, rampant digital cell phone use, including the use of short message service (SMWS), and the advent of Bluetooth devices. But the risks associated with the adoption of wireless networking are only now coming to light. A number of impressive......

...Networks are hardware, software, and media that can be used to connect computers together allowing them to communicate, exchange information and share resources. Networks allow multiple users to access shared data and programs. There are five kinds of networks; LAN, WAN, CAN, MAN, and HAN. The two main types of networks are LAN and WAN. LAN stands for local area network, and WAN stands for wide area network. According to our text “A local area network (LAN) is a data communication system consisting of several devices such as computers and printers.” (The McGraw−Hill Companies, 2006). These devices are physically connected to one another by cables, wireless media, or infrared links. Any network within a building or several that are next to each other is a LAN. A WAN, also known as a wide area network is made up of two or more LAN’s geographically connected. An example of a WAN is when a company or business located in one place has its main offices in one place and other smaller parts of the company in other places all data is shared within the network. There are also three types of hybrid networks, CAN’s, MAN’s, and HAN’s. A CAN or campus area network is like a LAN but on a bigger scale and more diversified, allowing different campus offices and organizations to be linked. For example, at a college the registrar’s office is connected to the bursar’s office. MAN’s which are metropolitan area networks are a large type of network that connects many corporate LANs together.......

...Network Attached Device Network-attached storage (NAS) is a dedicated hard disk storage device that is set up with its own network address and provides file-based data storage services to other devices on the network. It is attached to a local area network and assigned an IP address, allowing both application programming and files to be served faster because they are not competing for processor resources. NAS devices are usually configured with a web browser and do not have a keyboard or display. Consists of hard disk storage, including multi-disk RAID systems and can usually handle a number of network protocols, including Microsoft's Internetwork Packet Exchange and NetBEUI, Novell's Netware Internetwork Packet Exchange, and Sun Microsystems' Network File System. (Rouse, 2013) NAS devices speed is typically one gigabit Ethernet connection but this can be changed to multiple gigabit, 10 gigabit, fiber optic by adding a pci-e network card(s). Older parts can be used which may be limited to 10/100 megabit. If you need an exact answer for speed, simply look at the wiki on gigabit. The capacity range varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and add on hard drive controller cards there is hardly a limit on size. A board with 6 SATA ports can be replicated (1 to 5 port) allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage. As far as fault tolerance, raid 50...

...Network Design Following the acquisition of new premises comprising a two-story office in Adeplhi, Maryland this provides UMUC with the ability to revise and improve their network topology accordingly and ensure that not only is connectivity provided in a consistent fashion but also to provide the required security for information accordingly. One of the fundamental requirements is to ensure that data is segregated in terms of staff and students so this will require the creation of dedicated subnets accordingly to follow through and implement the solution, while there is also a requirement to provide wireless connectivity for students in the lobby area. Given that there is a specific opportunity to develop a comprehensive infrastructure it is important that the fundamental basis in terms of cabling is of a sufficiently high quality to support current and future operational requirements. Due to the size of the building there would be limitations if using Cat 5 based Ethernet cables for example and so therefore there should be a requirement to utilize Cat 6 based Ethernet as this will support a maximum cable length in excess of 300 ft without there being any connectivity or performance issues (Mitchell, 2014). Each of the two floors will have a designated server room that is designed to provide a central point of connectivity for all locations on that floor, and each of the rooms on the first and second floor will require a certain number of data ports based on their expected......

...Network Access Control (NAC) is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network.[citation needed] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access) into the network systems, allowing the network infrastructure such as routers, switches and firewalls to work together with back office servers and end user computing equipment to ensure the information system is operating securely before interoperability is allowed. A basic form of NAC is the 802.1X standard. Network Access Control aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over where users and devices can go on a network and what they can do. When a computer connects to a computer network, it is not permitted to access anything unless it complies with a business defined policy; including anti-virus protection level, system update level and configuration. While the computer is being checked by a pre-installed software agent, it can only access resources that can remediate (resolve or update) any issues. Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined within the NAC system. NAC is mainly used for endpoint health checks, but......

...2.1.1 Network History The history of computer networking is complex. It has involved many people from all over the world over the past 35 years. Presented here is a simplified view of how the Internet evolved. The processes of invention and commercialization are far more complicated, but it is helpful to look at the fundamental development. In the 1940s computers were large electromechanical devices that were prone to failure. In 1947 the invention of a semiconductor transistor opened up many possibilities for making smaller, more reliable computers. In the 1950s mainframe computers, which were run by punched card programs, began to be used by large institutions. In the late 1950s the integrated circuit that combined several, then many, and now millions, of transistors on one small piece of semiconductor was invented. Through the 1960s mainframes with terminals were commonplace, and integrated circuits were widely used. In the late 1960s and 1970s, smaller computers, called minicomputers came into existence. However, these minicomputers were still very large by modern standards. In 1977 the Apple Computer Company introduced the microcomputer, also known as the personal computer. In 1981 IBM introduced its first personal computer. The user-friendly Mac, the open-architecture IBM PC, and the further micro-miniaturization of integrated circuits led to widespread use of personal computers in homes and businesses. In the mid-1980s users with stand-alone......

... Networks, Telecommunications, and Wireless Computing | | | Telecommunication systems enable the transmission of data over public or private networks. A network is a communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together. Telecommunication systems and networks are traditionally complicated and historically ineffi cient. However, businesses can benefi t from today’s modern network infrastructures that provide reliable global reach to employees and customers. Businesses around the world are moving to network infrastructure solutions that allow greater choice in how they go to market—solutions with global reach.
