What is binary number system? Why is it used in computer system?
Answer:
Computers depend mainly on binary because it’s more time efficient for them to so.
Explanation:
It’s easier to identify 0 as “off” and 1 as “on”. As you may know, transistors are the fundamental blocks of microprocessors and ICs. The reasons this is the case is that these transistors form logic gates which can carry out basic logic operations. These logic gates are a huge step into making microprocessors/ICs/etc. And what do these logic gates depend on? They depend on binary.
Whoa whoa, wait a minute. Let’s first take a step back to know a thing or two about logic gates.
These logic gate can be constructed from transistors. They carry basic logic operations. You have one or more inputs “entering” the logic gate ——-> A certain operation is performed on them ——-> you get your output. The input is a voltage. This voltage it can be interpreted as an “on” or “off” according to the gate. Once again these offs and ons are 0s and 1s. For example the Inverter/NOT gate is a gate that simply takes an input and gives its inverse. For example:-
A low voltage/an “off” signal/ a “0” “enters” the NOT gate. ——-> A high voltage/an “on” signal/ a “1” is the result of the operation performed
(In the above example low voltage = “off” signal = 0, high voltage = “on” signal = 1)
As you can see, a 0 enters the NOT gate and a 1 comes out or vice versa. Now, if you were a logic gate, you’d prefer working with just 0s and 1s right? I would. This would be much easier to work with than a lot of different values.
It’s a herculean task to work with these though as a human. And fortunately, programming languages exist for giving the computer instructions to do in a “language” other than its own.

-used integrated circuits
IBM System/360, UNIVAC 1108, PDP-8/I, PDP-11/20 and PDP-11/45, etc.
mostly same I/O and memory as second generation
Fourth generation — 1971-present

Which of the following statements about RAID is correct? Group of answer choices All RAID configurations provide fault tolerance for up to one disk failure A RAID 1 configuration of 4 disks has higher storage capacity than a RAID 0 configuration RAID 5 allows up to two disk failures During a RAID 5 disk failure, read performance is not impacted A RAID 1 configuration of four 1TB disks has a storage capacity of 2TB
Answer:
A RAID 1 configuration of 4 disks has higher storage capacity than a RAID 0 configuration
Explanation:
Redundant Array of Independent Disks(RAID) are multiple physical drives arranged in logical units to provide data redundancy and increased performance. They are
RAID 1 configuration duplicates data storage, albeit of lower performance than RAID 0. Also called disk mirroring because it mirrors data on two or more disks, it provides at least two drives that are used interchangeably or together.
A RAID 1 is the configuration of the 4 disks that has higher storage capacity than a RAID 0 configuration. This option A is correct.
What is the RAID ?The RAID is a redundant array of the inexpensive disks and refers to the storage visualization technology that combines multiple physical disk drives. Its contract with earlies highly reliable mainframe disk drives.
The RAID one needs mini of two physical drives as the data is given simultaneously in two places. These drives are mirror images as ne fails the other can take over.

write difference between dvd r and dvd ram( Any 3 points or any a little big paraph for test)
Answer:
Following are the differences two the given questions:
Explanation:
DVD-R:
DVD-R is a common DVD recordable media that seems like a conventional DVD, and it can only be used once for writing data or analyzing information many times.It is identical to a regular DVD, however, it can be used to record data like a CD-R. Once a DVD-R is "burned," it cannot be read to anymore.There is a 650 nm range recording, nicknamed "Authoring DVD-R." "DVD-R for general" is another format with protection against duplicating, which records at 635 nm. Whilst DVD-R(a) and DVD-R(g) may read forms of one another, they cannot write formats of each other.DVD-RAM:
This is a technology for optical DVD storage where the information may be read, deleted & written constantly.It offers outstanding integrity of data, preservation, and avoidance of damages that can be used for basic storing data, data preservation, or data backup.Those disc drives can indeed be frequently recorded and deleted, and only compatible with DVD-RAM format devices produced by corporations.Your knowledge of algorithms helps you obtain an exciting job with the Acme Computer Company, along with a $10,000 signing bonus. You decide to invest this money with the goal of maximizing your return at the end of 10 years. You decide to use the Amalgamated Investment Company to manage your investments. Amalgamated Investments requires you to observe the following rules. It offers n different investments, numbered 1 through n. In each year j , investment i provides a return rate of rij . In other words, if you invest d dollars in investment i in year j , then at the end of year j, you have drij dollars. The return rates are guaranteed, that is, you are given all the return rates for the next 10 years for each investment. You make investment decisions only once per year. At the end of each year, you can leave the money made in the previous year in the same investments, or you can shift money to other investments, by either shifting money between existing investments or moving money to a new investement. If you do not move your money between two consecutive years, you pay a fee of f1 dollars, whereas if you switch your money, you pay a fee of f2 dollars, where f2 > f1.
a) The problem, as stated, allows you to invest your money in multiple investments in each year. Prove that there exists an optimal investment strategy that, in each year, puts all the money into a single investment. (Recall that an optimal investment strategy maximizes the amount of money after 10 years and is not concerned with any other objectives, such as minimizing risk.)
b) Prove that the problem of planning your optimal investment strategy exhibits optimal substructure.
c) Design an algorithm that plans your optimal investment strategy. What is the running time of your algorithm?
d) Suppose that Amalgamated Investments imposed the additional restriction that, at any point, you can have no more than $15,000 in any one investment. Show that the problem of maximizing your income at the end of 10 years no longer exhibits optimal substructure.

You work for a retail clothing chain whose primary outlets are in shopping malls and are conducting an analysis of your customers and their preferences. You wish to find out if there are any particular activities that your customers engage in, or the types of purchases made in the month before or after purchasing select items from your store. To do this, you will want to use the data mining software you are using to do which of the following?
a. Identify clusters
b. Identify sequences
c. Classify data
d. Identify associations
Answer: Identifying sequences
Explanation:
Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.
In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.
Therefore, the best option is B.
