Base two is also referred to as the binary number system.In the decimal system we use 10 different digits (0 to 9) to represent numbers. However, all numbers in binary consist of a combination of only 2 different digits; a "0" and/or a "1".All numbers can be represented using only these 2 digits.
The sum of binary numbers is also a binary number.
No and Yes... No because as such the two numbers are different and convention will define what the bit pattern should represent. However, with 16 bits, the UNSIGNED bit pattern for 32768 is the same as the SIGNED pattern for -32768 BUT the two numbers are being represented in different ways (ie in different number systems). If the binary representation is a SIGNED number then the top bit will be set if it is negative and with 16 bits the possible range of numbers is -32768 to +32767 and so it is IMPOSSIBLE to represent +32768. With an UNSIGNED number of 16 bits the top bit has no such special meaning and the range possible is 0 to +65535, so it is IMPOSSIBLE to represent -32768. ie it is IMPOSSIBLE with 16 bits to represent -32768 and +32768 in the same number system as they have the same bit pattern, BUT in different number systems the bit pattern can be used to represent the two numbers as the different number systems cannot represent BOTH -32678 and +32768.

Binary is simpler than decimal. And it is easy to represent binary numbers with signals, since only two states are required. For example, a low voltage state might represent a zero, and a high voltage state might represent a one. Or vice versa.
No.
The only numbers involved in the binary number system are one and 0. They are called binary numbers because it relates to exponents of the number two.
The binary number 10000000 represents the decimal 128
The term binary is applied to a number of different things, such as binary stars, binary numbers, or binary chemical agents. Your question should be more specific.

In order to answer that, it would first be necessary to know the numbers that "O", "K", and "A" represent.
110.101 is already a decimal number. Unless that is intended to be two binary numbers with a decimal point between them for some reason. (decimal points are not used to represent fractional numbers in the binary system).
