Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes. 
Impulse noise (also referred to as spikes) is the primary source of errors in data communications.  Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.

The major types of systems in the organization are:
- Operational Level system
 - Management Level system
 - Strategic Level system  
 
The classification of information systems based on organization levels is determined by the specialties and interests in some functional areas.
Operational-level systems assist operational managers by tracking the organization's basic operations and transactions, as well as the movement of materials in a factory. The primary function of systems at this level is to respond to routine inquiries and to record the movement of transactions via the organization. In general, information must be easily accessible, up to date, and accurate.
Management-level systems support middle managers' observing, regulating decision-making, and administrative operations. The primary question tackled by such systems is:
-  Are things running smoothly?
 
 Management-level systems usually give regular reports rather than real-time operational data. 
Strategic-level systems assist senior management in addressing strategic challenges and long-drawn patterns, both inside the organization and in the external world. Their primary focus is harmonizing external adjustments in the environment with current organizational capacity. 
Therefore, from the above explanation, we can conclude that we've fully understood the types of systems in the organization of information systems.

Answer:
Kindly check explanation 
Explanation:
The environment is our abode which aids the continued survival and growth of plant, animals and humans. The most important components and natural resources which are neceaaaarybto dwell and survive are all waht a makes up an enviromment. The energy derived from the sun aids power generation, plant growthbduring photosynthetic activities which is rewired to produce crops and feed us. The air we breathe are all a part of our enviromment. Therefore, such environment which provides a canvas or platform for our existence must be greatly cared for and no technological innovation, project or design must be allowed to impact negatively on the enviromment. Thus the need for impact assessment of systems in other to ensure that our abode isn't threatened.
