Interconnection devices 1.interconnection devices allow connection between devices examples of these are such as router, switch, wireless access points. 2.A wireless repeater resends a signal when it is received to increase the wireless signals reach. 3.A hub receives data and transmits it to all connected PCs but a switch stores the mac address for all connected pcs so will only transmit to specific PCs not all that are connected. 4.a network bridge connects two or more networks together and is similar to a switch because it sends the correct information to each connected pc .it can be hardware or software.
Router encryption: A router is a gateway to a network. The default password and username is public knowledge for most models. A typical attack, if a hacker gets into the router, is a DoS (Denial of Service ) attack.
6. True or False: NetStumbler can check for wireless networks and their signal strength, review which channels are being used, and then compare competing networks to monitor interference. 7. Wireless networks were identified by drawing
This will allow us to create a secure connection to the network over the internet. With this design the campus will have a much more reliable network to its
Every node sharing data transmission through a more reliable usage of the routing scheme, for balancing the left node energy and enhance the survival time of the whole network. 3. Fault tolerance: Routing protocols should have fault tolerance. WSNs nodes are susceptible to failure, therefore, a protocol should make full usage of the network information which is simply retrieve by a node for calculating routes, so as to assure that the routing failure can be recovered as soon as possible; multi-path transmission can also enhance the data transmission reliability. 4.
• ICMP; is one of the main rules of the internet protocol suite. It is used by system devices, like router, to send error messages showing, for example, that a demanded service is not offered or that a crowd or router could not be touched. • DHCP; Dynamic host configuration protocol is a customer server rules that repeatedly delivers an internet rules (IP) address and other linked arrangement information such as the subnet mask and avoidance entry. • Bluetooth; Bluetooth is a wireless communication technology that lets people to usefully connect their plans with other policies “and “the character of the technology is developing to not only allow devices to talk with one another, but actually allow the all-in-one communication between devices, native requests and the cloud.” •
Network internet layer This can be used to set the border line of what people can think of about the network. With this layer it will be able to interconnect with networks and will decide how the layers can do this process. It will be able to can concentrate and determine how the data will get from one remote network to the computer. Also it will take care with devices which are local. This is mainly tasked to take care of is routing which allows data to be moved the data across the series of networks which are connected.
9. What is the function of a network server? The function of a network server is to connect a group of workstations. It can communicate with the connected workstations and other devices.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
Devices like a hub or a switch; has much less capabilities as they are only capable of performing basic network functions. For example, a hub is usually used to transfer data between computers and network devices, but however, it doesn’t analyse or do anything with the data it contains. In the other hand, routers can analyse the data being sent and transferred over a random network, then change how it is packaged and once it has done that it can send it to another network. There are two different types of a routers out there, they are: the router and the wireless router. In the example picture above, the router allows all the computers and other network devices to access the internet.
Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 Andrew LeLusche Professor Gregory Roby Colorado Technical University 1/6/2017 Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 In order to choose the correct network for your needs, it is important to first understand the differences, advantages, and disadvantages between a peer to peer network and a client/server network. Whether you are a family home, a mom and pop shop, a data center or large corporation- there is a network for your needs. A network is a system of operating machines that allows a user to access an interface suitable for creating and saving documents, access webpages and video/audio content, run administrative programs to serve clients based on whatever business model or service provider you are. First let’s discuss a peer to peer network.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
Relational Database Management System: This type of database management system that stores the data in the form of related tables. It is a social database administrator which deals with some typical kind of queries and uses SQL for the development of the database. This type of database is a very powerful database as it deals with the relations which makes the data manipulations easier other than any other database. It has the features of data entry, data deletion, and creating of new entry and records etc. the database provides the ease of accessing and maintaining data easily.
Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.
Introduction: The term 'advanced development technology ' in construction industry covers an extensive variety of present day techniques and practices that envelop the most recent improvements in materials technology, design methodology, amount studying, offices management, administrations, structural examination and design, and management skills used in construction industry. Technological advancements in different fields such as medical industry, business industry, electrical engineering, mechanical engineering, civil engineering etc. have brought many positive impacts. Fusing advanced development technology into construction industry can expand levels of value, proficiency, safety, maintainability and incentive for money. The advanced technologies in construction industry are very useful for all type of small and large scale construction projects.
