Correct Answer
B. Arithmetical Logical Unit
Explanation
The Arithmetical Logical Unit (ALU) is responsible for processing data in the form of calculations and logic operations. It performs arithmetic operations such as addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, and NOT. The ALU is a crucial component of the CPU as it carries out the actual computations and logical decisions required by the computer program. It works in conjunction with the Control Unit to execute instructions and manipulate data within the CPU. The North Bridge and South Bridge are components of the motherboard that handle communication between the CPU and other parts of the computer system.
8.
Memory internal pada komputer yang mempunyai sifat penyimpanan tetap adalah ....
Correct Answer
A. ROM
Explanation
ROM stands for Read-Only Memory, which is a type of computer memory that retains its data even when the power is turned off. It is non-volatile and cannot be easily modified or erased. ROM is used to store permanent instructions or data that are essential for the computer's operation, such as the BIOS (Basic Input/Output System). Unlike RAM (Random Access Memory) or hard disk, ROM cannot be written to or changed by normal computer operations. Therefore, ROM is the correct answer as it is a type of computer memory that has the characteristic of permanent storage.
9.
Di bawah ini adalah merupakan bagian-bagian dari keyboard, kecuali ....
Correct Answer
C. Reset button
Explanation
The given options are all parts of a keyboard except for the "reset button." A function key is a key on a computer keyboard that is programmed to perform specific functions in various software programs. A numeric key is a key that includes numbers, usually arranged in a numerical pad on the right side of the keyboard. A typewriter refers to a machine used for writing in which characters are produced by striking keys. However, a "reset button" is not a part of a keyboard but rather a separate button that is usually found on electronic devices to reset or restart them.
10.
Di bawah ini adalah hardware komputer yang termasuk input device, kecuali ....
Correct Answer
D. CPU
Explanation
The CPU (Central Processing Unit) is the main component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions and coordinating the activities of all the other hardware components. Unlike the other options listed (scanner, keyboard, and mouse), the CPU is not an input device. It does not directly receive input from the user or external sources. Therefore, the CPU is not considered an input device in the context of computer hardware.
11.
Tipe monitor yang meiliki resolusi hingga 1024 x 768 adalah ....
Correct Answer
C. XGA
Explanation
The correct answer is XGA because XGA stands for Extended Graphics Array, which is a display resolution of 1024 x 768 pixels. VGA, CGA, and Green Monitor do not have a resolution of 1024 x 768, making them incorrect options.
12.
Hardware yang berfungsi sebagai alat pencetak adalah ....
Correct Answer
B. Printer
Explanation
The correct answer is printer. A printer is a hardware device that is used to produce hard copies of documents or images from a computer. It is specifically designed for printing tasks and is capable of reproducing text and graphics on paper or other physical media. Unlike scanners, monitors, and keyboards, which have different functions, a printer is specifically used for printing purposes.

Di bawah ini, urutan yang benar tentang satuan ukuran kapasitas memory komputer adalah ....
Correct Answer
A. Bit - Byte - Kilo Byte - Mega Byte - Giga Byte - Tera Byte
Explanation
The correct order of memory capacity units in a computer is bit, Byte, Kilo Byte, Mega Byte, Giga Byte, and Tera Byte. This order starts with the smallest unit, bit, which represents a single binary digit. Byte is the next unit, which is equal to 8 bits. Kilo Byte represents 1024 bytes, Mega Byte represents 1024 kilo bytes, Giga Byte represents 1024 mega bytes, and Tera Byte represents 1024 giga bytes. This order follows the convention of increasing size as the units progress.
