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:
Network diagram is the type of graphical networking chart that is basically used in the various type of computer telecommunication. The network diagram is useful for the networking designer and also for the network engineer for compiling the network documentation in detail.
Wiring semantic is the type of open source prototype platform which basically composed of the programming language and the IDE ( Integrated development environment). The wiring semantic consumer can affect the triggering the new data or information from the existing concepts.
Answer:
Increased processor speed and multi core technologies.
Explanation:
The development of processors over the years is overwhelmingly fast. The CPU use to be cumbersome, expensive and computational speed was moderate.
As it evolves, the CPU was minimized to give rise to microprocessors.
Microprocessors are very fast, running millions of processes on its core. The multiple core processors helped to increase the speed of these processors.
When there are more than one core in a processor (dual, quad or octal core), it processes data in parallel reducing the time of execution compared to a one core processor.
A company having computers with single core would need to upgrade to a new computer with multi core processor to promote speed in data processing.
Sharing network resources requires abiding by certain constraints, as follows:
<span>Security: Organizations present ongoing opportunities for unauthorized shared resources. Security mechanisms should be implemented to provide efficient parameters.Compatibility: Various client-server operating systems may be installed, but the client must have a compatible OS or application to access shared resources. Otherwise, the client may encounter issues that create communication delays and requires troubleshooting.Mapping: Any shared OS hardware drive, file or resource may be accessed via mapping, which requires a shared destination address and naming conventions.<span>File Transfer Protocol (FTP) and File Sharing: FTP is not affected by shared resources because the Internet is FTP’s backbone. File sharing is an LAN concept.</span></span>
Explanation:
Check the type of hard drive installed.
hope this helps you ❣️
