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.

Pig Latin is ______ and fits very naturally in the pipeline paradigm while SQL is instead declarative.
alisha [4.7K]

Answer:

Option b) is correct

Explanation:

Pig Latin is a language game in which English words are altered either by adding a suffix or such kind of suffix can be created by adding a syllable (vocalic). For example, ''hello'' becomes ''ello-hay''.

Pig Latin is <u>procedural</u> and fits very naturally in the pipeline paradigm while SQL is instead declarative.

What is the difference between computer architecture and computer organization?
alukav5142 [94]
The distinction between "computer architecture" and "computer organization" has become very fuzzy, if no completely confused or unusable. Computer architecture was essentially a contract with software stating unambiguously what the hardware does. The architecture was essentially a set of statements of the form "If you execute this instruction (or get an interrupt, etc.), then that is what happens. Computer organization, then, was a usually high-level description of the logic, memory, etc, used to implement that contract: These registers, those data paths, this connection to memory, etc. Programs written to run on a particular computer architecture should always run correctly on that architecture no matter what computer organization (implementation) is used. For example, both Intel and AMD processors have the same X86 architecture, but how the two companies implement that architecture (their computer organizations) is usually very different. The same programs run correctly on both, because the architecture is the same, but they may run at different speeds, because the organizations are different. Likewise, the many companies implementing MIPS, or ARM, or other processors are providing the same architecture - the same programs run correctly on all of them - but have very different high - level organizations inside them.

Which of the following is generally true about Open Source Software?
JulijaS [17]
<span>Open source software is usually free to download and install, and it can be studied, changed, and distributed according to the rights of the software. I don't believe there is any copyright laws on this type of software. The most known open source software is Linux and it's available for most operating systems right now. Typically, open source owners just ask for donations for their work.</span>

What is the data transmission time, assuming no errors or overhead, to send a 2 GByte file over a link with a 2 Gbps line rate?
schepotkina [342]

Answer:

The data transmission time will be 8 seconds (8.0s)

Explanation:

Using the formular:

T =A/S

T=Time = ?

Amount of Data = A = 2GByte

Speed = S = 2Gbps

The units of A and S are different

A is expressed in Bytes(B)

S is expressed in bits(b)

But :

1 Byte(B) = 8 bits(b)

T = A/S = 2GB/2Gb

since 1 Byte = 8 bits

T = 2 × G ×( B =8bits) / 2 × G × b

T = 2 × G × 8b / 2 × G × b

T = 2 × G × 8 × b / 2 × G × b

The common terms(2,G,b) cancel out

T = 8 seconds
