Computer A uses Stop and Wait ARQ to send packets to computer B. If the distance between A and B is 40000 km, the packet size is

5000 bytes and the
bandwidth is 10Mbps. Assume that the propagation speed is 2.4x108m/s
a) How long does it take computer A to receive acknowledgment for a packet?
b) How long does it take for computer A to send out a packet?

The time that it takes the computer to receive acknowledgment for a packet is 0.1667 seconds. The time it takes to send out a packet is  4 x 10⁻³seconds

<h3>1 The acknowledgment time for the packet</h3>

speed =  2.4x108m/s

Distance = 40000 km,

Time = distance/ speed

= 40000 x10³/ 2.4x10⁸m/s

= 0.1667

The time that it take is 0.1667 seconds.

b. Number of bytes = 5000

5000x 8 = 40000bits

10 mbps = 10000 kbps

10000 kbps = 10000000

packet size / bit rate = 40000/10000000

= 4 x 10⁻³seconds to send a packet out

deff fn [24]

Answer:

Reorder terms.

y=52x−1

Cancel the common factor of 22.Factor 22 out of −2-2.

y−4=5x2+52⋅(2(−1))y-4=5x2+52⋅(2(-1))

Cancel the common factor.

y−4=5x2+52⋅(2⋅−1)y-4=5x2+52⋅(2⋅-1)

Rewrite the expression.

y−4=5x2+5⋅−1y-4=5x2+5⋅-1

Multiply 55 by −1-1.

y−4=5x2−5

The pci express version 4.0 can provide up to what amount of throughput with 16 lanes for data?
netineya [11]

The PCL express version 4.0 can provide up to 32 gigabytes with 16 lanes for data.

<h3>What is PCI Express?</h3>

PCI Express, often known as PCIe or PCI-e, is a high-speed serial computer expansion bus standard that was developed to replace the previous PCI, PCI-X, and AGP bus standards.

Thus, it is correct to state that the PCL express version 4.0 can provide up to 32 gigabytes with 16 lanes for data.

MakcuM [25]

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment

Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :

EMI

RFI

Explanation:

  • EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
  • During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
  • EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
  • Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
  • The internal circuits of personal computers generate EM fields in the RF range.
