What decimal value does the 8-bit binary number 10011110 have if it is on a computer using two's complement representation?
The 8-bit binary number 10011110 have decimal value of -98 if it is on a computer using two's complement representation.
The MSB displays the sign in the 2's complement representation of binary integers by using a '0' for the positive sign and a '1' for the negative sign. Magnitude representation is done using the remaining bits. The largest value that an 8-bit binary number can represent is decimal 255, or binary 11111111. Its calculated as follows: 1*128 +1*64+1*32+1*16+1*8+1*4+1*2+1+1 = decimal 255.

If you have a computer with three hard disks, what type of raid fault-tolerant configuration will make best use of them?
Answer:
RAID 1 or RAID 5
Explanation:
RAID 1 mirrors data across all disks, if you lose 1 disk, you still have 2 copies of that disk.
RAID 5 spreads data evenly across all disks with parity, if you lose 1 disk then lost data can be reconstructed. If you lose 2 disks then all data is most likely lost.
RAID 1 is ideal for important information. RAID 5 is ideal for storage efficiency and security.

What law projects network bandwidth will grow at least three times faster than computer power, whcih means that if bandwidth doubles every 12 months, every 10 years, the network bandwith will have 1000 times greater capacity?.
Answer: Gilder's Law
Explanation:
Bandwidth grows at least three times faster than computer power. While computer power doubles every eighteen months (Moore's law), communications power doubles every six months.
Gilder's Law is the law projects network bandwidth will grow at least three times faster than computer power.
What is Gilder's Law?The overall bandwidth of communication systems triples annually, according to George Gilder's Law, which he proposed as a prolific author and pioneer of the modern technological era. Recent events, which seem to show that bandwidth availability will expand at a rate that does, seem to validate Gilder's Law.
According to Metcalfe's Law, the value of a network increases as it grows. Moore's Law states that as capability increases, so are the costs associated with using such capabilities. They all suggest that continuing network growth cannot be stopped.
Bandwidth rises at least three times faster than computer power, according to Telecosm author and visionary George Gilder. Moore's Law states that if computing power doubles every 18 months, communications power should do the same.
Thus, Gilder's Law is the law.

How can I design a digital prototype from a paper prototype?
2 Sentences!!
To get a digital prototype from a paper prototype, the designer should endeavor to:
Note the design that they want to test and draw them with the use of markers. Then, they can convert these to digital form and run them.How can a digital prototype be created?A digital prototype can be created by first understanding the design that is to be created. Designers can either choose to have a digital or paper prototype. The problem with the paper prototype is the fact that it does not allow for user interaction. However, it is still a good way to understand things like color schemes.
So, when a designer gets an idea, he or she can note this on paper and even make some colorings that will allow for a better understanding of the material. Next, they can create the digital form of the design and test run this on a system. When they follow all these steps, they will e able to obtain a better result.
