Cisco Chapter 9 Study Guide

You have been hired to upgrade a network of 50 computers currently connected to 10 Mbps hubs. This long-overdue upgrade is necessary because of poor network response time caused by a lot of collisions occurring during long file transfers between clients and servers. How do you recommend upgrading this network? What interconnecting devices will you use, and what benefit will you get from using these devices? Write a short memo describing the upgrade and, if possible, include a drawing of the new network.

PRACTICE 3: Do you know how to make sentences using the correct form so that they are parallel? Think!

is as good as the unitary nanosecond, and thus the delays in arrival time produced by the

Today the CertBlaster® Network+ N10-006 practice tests helps you prepare for CompTIA’s Network+ N10-006 exam. With over 500 practice questions similar to the ones on the actual exam, this is an exceptionally comprehensive and complete practice test offering. Here is a quick overview of the main features of the CertBlaster for Network+ exam preparation:

R17. With a length of 1000 km, a rate of 10 Mbps, and a packet size of 1 kB, the sender finished transmitting before the first bit of the packet reached the receiver. With a length of 10 km, a rate of 1 Mbps, and a packet size of 500 bytes, the first bit of the packet reached the receiver before the sender was finished transmitting.

Explain to the staffs what the expectations from them. Supervisors should inform their staffs the reasons to be initiative, and the benefits incurred for both individuals and organisations. When staffs take the initiatives, the results will be improved customer loyalty, cost cutting, new products invention and problem-solving processes.

1. Compose a theoretically sound and conceptually rich essay that demonstrates knowledge of fundamental subject areas of a student’s academic discipline and specialization.

Each link can make sure that an IP datagram sent over link which can be received at the other end of the link and there is no errors during this process. However, IP datagrams may not be in the proper order when they arrive at the ultimate

Ans: Sequence numbers are necessary for a receiver to find out whether an entering packet has new data or it is a retransmission in reliable data protocol.

1. A technician arrives and asks a customer, "Can you describe the problem?" The customer replies, "All email messages that I send have the wrong date. I have restarted the computer several times, but this does not seem to help."

Multipoint video conferencing - allows the transmission of audio and video signals between several (more than two) locations. In this mode you will need to use additional network devices such as video conferencing servers (video conferencing bridges), gateways, gatekeeper, etc. In this mode you can make another division into:

Units like "trillion skimming point operations for each second (Teraflops or TFLOPS)" give a metric to separating the cost of grungy enlisting after some time or by the producer. A benchmark can be utilized to quantify throughput. In information transmission, arrange throughput is the measure of information moved suitably starting with one place then onto the accompanying in a given period, and reliably measured in bits reliably (bps), as in megabits reliably (Mbps) or gambits reliably (Gaps).

Ethernet II framing structure is also commonly referred to as DIX Ethernet (Carrell, Chappell, Tittel & Pyles, 2013). This frame structure was developed by DEC, Intel, and Xerox and thus the DIX acronym that represent these major players in its development (Carrell et al., 2013). The Ethernet II defines a two-octet field of EtherType (Carrell et al., 2013). The MAC address and the destination come before this Ethernet frame. This precedence helps in the identification of the upper layer of the encapsulating protocol (Carrell et al., 2013). This Ethernet standard has a unitary data link layer. Besides, the type field in use in Ethernet II helps to extricate between different client protocols. Moreover, the Ethernet II applies the MAC frame format in its TCP/ IP protocol (Carrell et al., 2013). The minimum frame size for Ethernet II is 64 bytes while the maximum frame size for the same Ethernet II is 1518 bytes (Carrell et al., 2013). The introduction of VLAN made the maximum frame size to be increased to 1522 bytes to accommodate VLAN tagging (Pyles, Carrell, & Tittel, 2016). The preamble in Ethernet II is 8 bytes long while the destination address contains a data link address field that is 6 bytes long (Carrell et al., 2013). Furthermore, the source address field and type field are 6 bytes and 2 bytes respectively (Carrell et al., 2013).

Data transmitted on a network is a packet, which is a sequence of zeros and ones (binary) (Strangio, 2016). Packets are first wrapped in a frame, which has all the labels or addresses of both the sending and receiving computers on the network. When a router receives a packet, it examines the frame to see who sent it, and to which device on the network is it going to, then it forwards the packet to the destination. Below in a chronological order of how computer A will send a data (packet) to computer B on the network above.
