Answer:
letter C
They only have one chip with two complete microprocessors on it, both of them share one path to memory and peripherals.
Answer:
D
Explanation:
Two dimensional array contain both rows and columns. Each row represented one record and each column represent one filed in that record.
for ex: int grades[5][3];
here array grades contains 5 rows and in each row we have 3 columns
if we have grades[i][j] then " i " represents number of rows and j represents the number of columns in that row.
j<grades[i].length represents i=0 to 2[here no of columns are 3, array index starts from 0 to 2]
The Answer is D
Answer:
RAM
ROM
PROCESSOR
MOTHER BOARD
HARD DISK
Explanation:
Random access memory or RAM store data temporary
Read only memory or ROM permanently store data and have a programming needed to start (PCs) or other electronic device
CPU or processor refers to brain of computer
Mother board the main internal hardware component of system unit
Hard disk is electro mechanical data storage
The answer is ascending because ascending is the numbers from smallest to largets
