Which of the following is the main circuit board of the system unit group of answer choices?
The System Unit. The Motherboard is the main circuit board for the computer, containing both soldered, nonremovable components along with sockets or slots for components that can be removed. The motherboard holds the CPU, RAM and ROM chips, etc. The Central Processing Unit (CPU) is the “brain” of the computer.

When 8 bits are grouped together as a unit they form a?
byte
The binary system is a number that has just two unique digits, 0, 1, called bits. Bit is the smallest unit of data the computer can represent. When eight bits are grouped together as a unit, they form a byte, which provides enough different combinations of 0’s and 1’s to represent 256 individual characters.
What is the main circuit board inside the computer that connects different parts of computer together?
Motherboard
The correct answer is the Motherboard. The motherboard is the main circuit of the computer. It is also called a system board or logic board. It holds and allows connection between all the peripheral devices of the computer.
Which number system is used by a computer?
binary numeral system
In computers, the main numeral systems are based on the positional system in base 2 (binary numeral system), with two binary digits, 0 and 1. Positional systems obtained by grouping binary digits by three (octal numeral system) or four (hexadecimal numeral system) are commonly used.
When 8 bits are grouped together as a unit they form?
Common binary number lengths Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte.
What type of ROM chips contain permanently written data?
Firmware and its use Sometimes the chips come with pre-written data that is these contain permanent data, instruction or information written on it.
What numbering system uses only the numbers 0 and 1?
Binary number system
Binary number system, in mathematics, positional numeral system employing 2 as the base and so requiring only two different symbols for its digits, 0 and 1, instead of the usual 10 different symbols needed in the decimal system.
