<u>Implication of technological literacy to a teacher training today
:</u>
- First of training has to be under technology literacy before training starts. Trainer also should have enough knowledge on technology literacy.
- Trainer can take printed materials to share the document on the topic which to be covered and circulated to trainers
- Since it given as general topic, training teacher has to cover the following topic, general on computer and purpose of computer today's life, life cycle of computer grown from old PC to laptop and tablet.
- Next topic such be covered operating system and explain about the operating system and different technology is used.
- Revolution on technology should be also covered and explained in details.
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.
Answer:
In designing LAN networks, network designers tend to design err on the side of providing for less capacity than what is currently necessary.
Explanation:
In designing LAN networks, network designers tend to design err on the side of providing for less capacity than what is currently necessary is not true about network design.
