Answer: Local Area Network (LAN)
Explanation:
A Local Area Network (LAN) is a computer network that interconnects computers within a limited physical area such as a residence, school, laboratory, university campus or office building.
An example of LAN network is "Phone, Computer and TV connected to a single network (such as a Home Network) via Cables, Wifi, Bluetooth or Hotspot". When the devices are interconnected or connected to a LAN, it becomes accessible between each other.
A simplest example of a LAN Device is a <em>Home Router.</em>
Answer:
•Make sure doorway openings are at least 32 inches wide and doorway thresholds are no higher than 1/2 inch.
•Keep aisles wide and clear for wheelchair users.
•Make sure all levels of the lab are connected by a wheelchair-accessible route of travel.
For students with mobility impairments, make sure there are procedures in place for retrieving materials that may be inaccessible.
Make sure ramps and/or elevators are provided as an alternative to stairs. Elevators should have both auditory and visual signals for floors. Elevator buttons should be marked in large print and Braille or raised notation and easily reachable for wheelchair users.
Locate the lab near wheelchair-accessible restrooms with well-marked signs.
Service desks need to be wheelchair-accessible.
Provide ample, high-contrast, large-print directional signs throughout the lab. Mark equipment in the same fashion.
Provide study carrels, hearing protectors, or private study rooms for users who are easily distracted by noise and movement around them.
Provide at least one adjustable-height table with easily reachable controls for each type of computer.
Have wrist rests available to those who require extra wrist support while typing.
Keep document holders available to help users position documents for easy reading.
Answer: The goals of computer security are to protect computers and users from data theft or loss as well as damage to any part of the computer.
Explanation: Common means of achieving computer security are firewalls, anti-virus software and this can fail due to hardware problems or
weaknesses that prevent malicious attacks.
To answer this question, think of a time when you experienced any one of these. For example, personally, I was once an unfortunate victim of a general malicious attack that took advantage of a weakness in my anti-virus software. After clicking on a link on a dodgy website, a virus was installed on my computer. My computer finally crashed, without any hope of restarting it. I lost all my data and I had to buy a new computer. This was a malicious attack.
However, sometimes people can be specifically targeted to steal their data or monitor their activities.
Answer:
Line second and third i.e, "typing the cell name, like "B4" and clicking the cell to reference
" the correct answer.
Explanation:
It relates to some kind of set of cells on the worksheet, which could be used to calculates the formula. It also helps to locate the information, which you want to analyze in the calculation. It can also provide the cell reference in more than one formula in the same worksheet, that relates to Information on many other workbooks, and wrong choices can be described as follows:
- Hovering provides the basic details, in which we hover, that's why it is wrong
.
- Zooming is used in projection, it can't be used in the cell reference, that's why it is wrong.
Answer:
348 + 395 = 743
Hence, together they have 743 pennies and not 653 pennies. And we cannot perform the rounding, as that is the case when we have the decimal number or the float number. Only then we have the digits after the decimal. And if it's more than 5, we add 1 to the previous or else leave the number as it is. And we go on performing from right to left, and till the number of decimal places, we need to round off. However, here its purely an integer, and hence we cannot round off, as that will result in a significant loss, and which is not acceptable. However, if we want to round off before decimal places as well, then in that case 743 will be $7s, and 653 pennies will be 6+1= $7s, and if this level of loss is acceptable then we can assume that they have the same sum of money. However, here the answer is given in pennies, and hence this is not the case. And hence the answer given in the question is not correct.
Explanation:
The answer is self-explanatory. And since both are numbers, rounding is not required(as explained in the answer section), as it is required in case of decimal and float(as explained in the answer section). And as explained in the answer section, if we can tolerate very heavy loss, then the numbers as well can be rounded off as explained in the answer section. But that is not the case here, as the answer is given in pennies.
