2. True or False, labeled as T/F ( 20 points) Remember to write the answer in the following form. (1) Arithmetic unit is the core part of arithmetic logic operation unit although it has many parts. (2) A storage unit is a collection of all storage elements that hold two bytes. (3) The purpose of using 2's complement in computer system is to simplify the design of computer. (4) The 1 's complement representation of ' 0 ' is unique. (5) DRAM is faster than SRAM, but its integration is lower. (6) The speed of a computer is related to frequency, and is also related to word length, computer architecture, etc. (7) Compared with external memory, internal memory is characterized by small capacity, fast speed and high cost. (8) The condition for responding to an interrupt request is when the peripheral work is done and the interrupt flag trigger is " 1 ". (9) The purpose of adding a Cache between the main memory and the CPU is to increase the capacity of the main memory. (10) In disk storage, the search time is the time required to move the head to the cylinder to be found. \&Computer Principles\$ Final-term Exam 3.
