Explanation:
The use of numerical systems arose from the need of man to improve certain mathematical calculations as time goes.
Several factors demanded the study and application of mathematical operations using decimal numbers. Among these factors, technological advancement essentially from the first experiments in the use of electronics.
There are several numeric systems, but four of them stand out: decimal, binary, octal and hexadecimal.
The decimal system is used every day in countless ways and, no doubt, is the most important number system. He has ten digits with which can form any number through the law.
Non-decimal systems such as binary, octal and hexadecimal are critical in the areas of digital and computer techniques. Through these systems is possible to perform logical combinations and working with computer programming languages. This article will show the link between the logical circuits and these numbering systems.
2 - The Binary Numbering System
The binary numbering system is composed of only two digits:
Zero (0)
One (1)
To represent zero amount using the number 0; to represent a quantity, use the digit 1.
Assuming you need to represent the number two. Which digit you can use, if there is no number 2 in that system?
We have the following response. In the decimal system, we do not have the number ten and represent the amount of ten using the digit 1 followed by the digit 0. In this case, the number 1 means that we have a group of ten and the digit 0, no drive, which means ten.
In the binary system, do likewise. For you the amount of two, we use the digit 1 followed by the digit 0. The figure 1 means that there is a group of two elements and 0, a group of any unit, thus representing the number two.
The table below helps us to understand the differences between the decimal and binary system, using this rule. The number sequence displayed to the number nine.

2.1 - System Conversion binary to Decimal System
To better understand the conversion we use a decimal number either, for example, 356. This number means:
3 x 100 + 5 x 10 + 6 x 1 = 356
Hundred ten unit
3 x 10 � + 5 x 10 � 6 x 10 + 10 = 356
We realize that the least significant digit (6) multiplies the unit (1), the second digit (5) multiplies the ten (10) and the most significant (3) multiplies the hundred (100). The sum of these results will represent the number.
In General, the formatting rule of a number is the sum of each digit multiplied by the corresponding base (in the example, the number ten) high for an index as the positioning of the digit in the number.
In another situation, we will use a binary number, for example, the number 101. We can conclude that it is equivalent to number 5 in the decimal system. Using the concept of a number, we will convert the number to the decimal system as follows:
1 0 1
1 x 2� + 0 x 2� + 1 x 2

I need urgent help. which of these network has minimum data loss. a. LAN b. MAN c. WAN
Answer:
The correct option is;
a. LAN
Explanation:
The computer networks listed vary in their transmission medium from the wired transmission medium using the network cable for the Local Area Network (LAN) network, to the wireless transmission network used in the Wide Area Network (WAN), while the Wide Area Networks, (WAN) consists of several LAN networks connected to a larger network through telephone lines.
Of the three network types, the type that has the least amount of data loss is the LAN, due to its structure, being the smallest unit of wired network that can handle direct port to port data flow through physical network switches, which ensures sufficient bandwidth and lesser opportunity for congestion which results in packets of data losses.
By changing the field size for text to the maximum number necessary,
A. The file will not take up as much space on the database
B. The field will autocorrect any terms over the size
C. The field will select the most important information if over the text limit
D. The file will be stored in a different format.
Answer:
The correct option is;
A. The file will not take up as much space on the database
Explanation:
Changing the field size of a field that does not contain data limits the size of taken up by the data values added to the field. The field size for text field determines the disc space that each value of the field allowed to take up by Access
When the field size is changed for fields containing data, the data values in the field that have values higher than the maximum field size are truncated while the field size of subsequent data are limited as stated above.
