Major innovation made from establishment of abacus to the development of fifth dev of computer generation

Computers and Technology

expeople1 [14]3 years ago
7 0

<u>Explanation</u>:

The establishment of the Abacus brought about one of the first counting device (calculator). This device was a mechanized computer that supported numeric calculations. However<u>, the process was entirely manual and mechanized. </u>This innovation led to;

First-generation  of computers, although not entirely manually operated like Abacus, made use of vacuum tubes, were very big in size and could store only a small amount of information.

Second Generation of computers unlike the first generation that uses vacuum tubes, this one came with new technology; the use of transistors. The computers were smaller in size than vacuum tubes.

Third Generation  computers made use of IC (Integrated circuits) for the first time. Contained higher storage capacity and was more reliable than previous generations.

Fourth Generation computers became known as the personal computer generation. This generation brought the use of personal computers on a personal level as they use microprocessors, was easy to carry about, had larger storage capacity and faster speed of operations.

Fifth-generation of computers is known as the age of artificial intelligence. These computers were programmed with the ability to make decisions just like a human being would.

Answer:

Explanation:

demo.java Shapes 2 Shapes Polymorphism Create a set of classes derived from an abstract class Shape, which provides a common interface, for managing various 2D geometric shapes. In our model, each Java object will represent a shape somewhere in a Cartesian coordinate system. However, note that unlike in Mathematics, the positive y-axis grows down from the origin. Shapes All shapes have the following properties: color, area, perimeter, location, and bounds. Shapes are mutable, for example any shape can be moved.

Drag each label to the correct location on the image.
andrezito [222]

Answer:

1.) Relative cell reference - A1

2.) Absolute cell reference - $D$2

3.) Mixed cel reference - $D2

Explanation:

In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.

A cell reference is a cell address or a range of cell addresses that can be used in a formula.

There are three types of cell references and they are;

a) Relative reference

b) Absolute reference

c) Mixed reference

A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.

An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.

Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.

You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav
asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

<u>RAID 0:</u> does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

<u>RAID 1:</u> Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

<u>RAID 5:</u> Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is \frac{n-1}{n} of the total disks: \frac{7}{8} of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.

Which of the following is a valid IP address that can be used on the Internet (meaning the public addressing scheme)? Group of a
VladimirAG [237]

Answer:

168.16.1.1 is correct.

Explanation:

168.16.1.1 is the legitimate Internet Protocol address that can be used on the Internet.

Internet Protocol 10.10.1.1 and internet Protocol 172.30.1.1 are the private internet protocol addresses so they could not be used on the internet.

The Internet Protocol 234.1.1.1 has been used as a multicast address so they may not be used on the Internet.
