D. leased lines 2. What is WiMAX designed to do in WAN designs? D. To provide wireless access to fixed locations spanning large areas 3. What does DHCP do in a network? D. It is a protocol used by hosts to dynamically obtain an IP address (and other information) to use for a specified length of time.
Two TCP/IP data-link protocols are Ethernet and PPP. c Data-link protocols define addresses that identify devices connected to the underlying physical link. 18. a. It focuses mostly on the network between endpoints, rather than the endpoints. c. IP provides logical addressing and routing services.
It contains many routers that work independently, without network connection to the other routers. 4. Which of the following answers lists a fact that is true about a Tier 1 ISP, but not true about a Tier 2 ISP? C. Typically has many redundant high-speed links to other ISPs. 5.
__________protocols__________ are sets of rules used by communication devices. 3. The _______network_____________ layer of the OSI model is responsible for creating, maintaining, and ending network connections. 4. The __________internet protocol, IP_______________ is the software that prepares a packet of data so that it can move from one network to another on the Internet or within a set of corporate networks.
The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network. A personal area network - PAN - is a computer network organized around an individual person. Personal area networks typically involve a mobile computer, a cell phone and/or a handheld computing device such as a PDA.
Though this may be quite often in using Carrier Sense Multiple Access or the presence of a bus master’s who controls access to the shared bus resource. A ring network is a network topology in which each node connects exactly to two other nodes, forming a single continual pathway for each node - a ring” (Conjecture Corporation, 2003). In a ring network data travels from each node to the
Task 1 p3 & p4: Task 3 D2: Since the information is encoded differently in analogue and digital electronics, the way they process a signal is consequently different. All operations that can be performed on an analogue signal such as amplification, filtering, limiting, and others, can also be duplicated in the digital domain. Every digital circuit is also an analogue circuit, in that the behaviour of any digital circuit can be explained using the rules of analogue circuits. The first electronic devices invented and mass produced were analogue. The use of microelectronics has reduced the cost of digital techniques and now makes digital methods feasible and cost-effective such as in the field of human-machine communication by voice.
Protocol - When computers communicate with each other, there needs to be a common set of rules and instructions that each computer follows. A specific set of communication rules is called a protocol. 11. HTTP – Hyper Text Transfer Protocol HTTP is the underlying protocol used by the World Wide. 12.
Describe the application layer of the TCP/IP model. (p344) Application layer roughly correspond to the OSI application and presentation layers and includes many protocols. 4. Describe the network interface layer in the TCP/IP model(p 344) Network interface layer roughly equivalent to the OSI data link layer. This layer connects internet protocol to underlying network protocols in the physical layer.
Unit 3 Exercise 1: Specifications – Definitions by: Timothy Robertson 1. Application- The technology that will take advantage of cabling systems. Applications include telephone systems, Ethernet, token ring, ATM, etc. 2. Unshielded Twisted Pair- A cable used in computer networking that consists of two shielded wires twisted around each other.
