Single-Mode Fiber uses a very narrow glass core and can transmit data at very high speeds or long distances. Multi-Mode Fiber uses a thicker glass core than single-mode fiber. As I have discussed each cabling solution has its own advantages and disadvantages. Copper cabling is best
Typically, the utilization of switch ports is low and can lead to higher costs compared to other implementations of the hierarchical star. 2. Placing horizontal cross-connections and work group switches closer to equipment outlets is called FTTE (fiber-to-the-telecommunications enclosure). The benefits include savings

Reducing operational surprises, aligning risk appetite and strategy, and reducing costs of control 2. Which of the following is not considered a component of enterprise risk management? a. Internal environment b. Internal auditing c. Objective setting d. Control activities 3.
It depends on why I need the RAID. If had a type of high traffic situation I would use, RAID 0 with a high speed situation, and I would use RAID 1 if I needed high availability. 7. What is the difference between software RAID and hardware RAID? Hardware RAID requires specialized hardware to handle the drives and is more reliable compared to software RAID.
ATM uses fixed size packets (53 bytes) for data communication; frame relay uses variable packet sizes depending on the type of information to be sent. Both information blocks have a header in addition to data block and transfer is connection oriented. Frame Relay is used to connect Local Area Networks (LAN) and it is not implemented within a single area network contrast to ATM where data transfers are within a single LAN. ATM is designed to be convenient for hardware implementation and therefore, cost is higher compared to frame relay, which is software controlled. Therefore frame relay is less expensive and upgrading is easier.
Explain the activity and your code. Write a 200- to 300-word short-answer response for the following: What are the advantages and disadvantages of sequential and random access files? Provide an example in which a sequential file is a better choice than a random access file. Explain why. Provide an example in which a random access file is better than a sequential file.

TORK CORPORATION COMPETITIVE COST ANALYSIS 1. What are the primary cost drivers for room air conditioning? How do the drivers differ between LG and Tork? The primary cost drivers are Design, Geography, Facility and Execution. The differences over cost driver between LG and TORK are mainly come from the followings, please see below: Design: LG uses the plastic parts which the weight is lesser than Tork steel’s part and also the cost are cheaper.
1. Describe the electromagnetic spectrum; make sure you discuss the patterns that occur with frequency and wavelength, as well as the different types of EM waves. Fiber optic data transmission systems send information over fiber by turning electronic signals into light. Light refers to more than the portion of the electromagnetic spectrum that is near to what is visible to the human eye. The electromagnetic spectrum is composed of visible and Near infrared light like that transmitted by fiber, and all other wavelengths used to transmit signals such as AM and FM radio and television.
Measuring the position Radio signals and codes Each GPS satellite transmits two radio signals, L1 (1575.42 MHz) and L2 (1227.60 MHz). The L1 signal is modulated with two pseudo-random noise (PRN) ranging codes, P-code and C/A code. The Precision or P-code can be encrypted for military use. The Coarse/Acquisition or C/A code is not encrypted. The L2 signal is modulated with the P-code only.
