Answer:
Cokies
Explanation:
Cokies are files that saves on a website server that enables the website to recognize a computer when it visit the website. So for the first time a computer visit a website, the website brings a little pop up that ask the user to accept Cokies and if the user accepts, the website will be able to recognize the computer when next it visit.
Answer:
Option 2: a type of mini chart that users can insert into a worksheet
Explanation:
A graph or chart is used to show trends and changes in a dataset.
When we have to show trends or changes in MS Excel, there are a lot of options available. One of them is Sparklines. Sparklines are like mini charts that can be used to show data graphically.
Hence,
The correct answer is:
Option 2: a type of mini chart that users can insert into a worksheet
From server do some file transfer to client PC to sync to the server.
<u>Explanation:</u>
As IT System administrator if PC or client or workstation or laptop not connected to network more than 3 months from windows server we need to refresh the connection and redo the connection from server to the client to do sync the activities.
Moreover from domain server refresh and re sync activities to establishing the connection.
Go to client PC or workstation or desktop login log and logout from the PC and login to domain account by changing the password.
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.
