This is called a "heat sink", essentially, a metal plate makes indirect <span>(its separated by thermal paste)</span> contact with the heat spreader of a cpu (central processing unit). The concept is that the heat sink is made of highly conductive materials thus conducting heat away from the CPU, quite often you'll find a fan attached to further disparate heat away from the heat-sink. These days you'll alternative cooling methods, the most common alternative is to use watercooling (another topic). GPU (graphic processing units) also have heatsinks.
Answer:
The answer is below
Explanation:
Computer System is widely known for its ability to perform its functions faster by giving out information.
The computer system operation follows certain principles, some of which are:
1. It makes use of the OPERATING SYSTEM to link the hardware and the software together, without it, the computer system is useless.
2. It works with INPUT DEVICES such as keyboards or stylus. Without input devices, there is no way humans can communicate with the computer system
3. It works with OUTPUT DEVICES such as monitors and speakers. Without output devices, there is no way computers can communicate or give back information to humans.
4. It works with the NETWORK such as LAN or WIFI to provides the sharing of data files to other users or computers. Without the network, the computer system can only work within certain spaces, with no way to share data or files with others far away.
Answer
First part:
The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.
Second part:
The invalid bit sequence are option a. 01001000 and d. 11100111
Explanation:
Explanation for first part:
In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.
If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.
If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.
Explanation for second part:
A valid odd parity bit sequence will always have odd number of 1s.
Since in option a and d, total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.
And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.
Answer:
C. Rulers indicate the margins, tabs, and indents in a presentation slide.
Explanation:
Answer:
Early school starting times cause poor performance on tests, inattention in class, and drowsiness.
Explanation:
Carskadon study on early school starting time showed that it cause increased rate of rapid eye movement sleep in students and they doze off during lecture. Insufficient sleep lessens attentiveness levels in the class which affects students' potential to learn. The study showed that students do not perform well on tests. In addition to the difficulty in learning, there is an increased danger of accidents for those who drive to school due to dizziness.
