Latihan soal untuk kompetensi dasar "Rangkaian Logika dan Gerbang Dasar Logika"

• 1.

### Dalam rangkaian logika gerbang logika yang manakah yang menghasilkan output 1 jika inputnya 0 dan outnya 0 jika inputnya 1

• A.

AND GATE

• B.

NAND GATE

• C.

OR GATE

• D.

NOR GATE

• E.

NOT GATE

E. NOT GATE
Explanation
The NOT gate is the correct answer because it is the only gate that can invert the input signal. When the input is 0, the NOT gate will output 1, and when the input is 1, the NOT gate will output 0. This behavior matches the condition stated in the question, where the output should be 1 when the input is 0, and the output should be 0 when the input is 1.

### Operasi aljabar untuk rangkaian logika AND GATE adalah ......

• A.

Y = a.b

• B.

Y = a + b

• C.

Y = a (+) b

• D.

Y = a O b

• E.

Y = a - b

A. Y = a.b
Explanation
The correct answer is y = a.b because in an AND gate, the output is true only when both inputs are true. In this case, y will be true (1) if and only if both a and b are true (1), and it will be false (0) otherwise. This behavior corresponds to the logical operation of the AND gate.

Rate this question:

• 3.

• A.

1971

• B.

1961

• C.

1991

• D.

1981

• E.

1891

A. 1971
Explanation
The first microprocessor, the Intel 4004, was introduced in 1971. This marked a significant milestone in the history of computing as it was the first single-chip microprocessor, combining the functions of the central processing unit (CPU) onto a single integrated circuit. The Intel 4004 had a clock speed of 740 kHz and was primarily used in calculators and other small-scale devices. Its introduction paved the way for the development of more powerful and complex microprocessors, leading to the modern-day computers and technology we have today.

### Yang menghubungkan semua komponen dalam unit mikrokomputer adalah .....

• A.

Dioda

• B.

Conector

• C.

Transistor

• D.

Led

• E.

Bus

E. Bus
Explanation
The bus is the component that connects all the components in a microcomputer unit. It acts as a communication pathway, allowing data and instructions to be transferred between the different components, such as the processor, memory, and input/output devices. Without the bus, the components would not be able to communicate with each other and the microcomputer would not function properly.

### Data dalam RAM bersifat volatile, artinya adalah ....

• A.

Permanen

• B.

Aktif berkala

• C.

Akan hilang bila power mati

• D.

Dibaca dan ditulis

• E.

Hanya dapat dibaca

C. Akan hilang bila power mati
Explanation
The correct answer is "akan hilang bila power mati". This is because data in RAM (Random Access Memory) is volatile, meaning that it requires power to maintain its stored information. When the power is turned off or lost, the data stored in RAM will be lost as well. Unlike permanent storage devices like hard drives or solid-state drives, RAM is not able to retain data without a continuous power supply.

### Mikroprosesor pertama yang digunakan untuk komputer di rumah adalah

• A.

Intel 4046

• B.

Intel 80286

• C.

Intel 80386

• D.

Intel 8080

• E.

Intel 4004

• F.

Intel 80486

B. Intel 80286
Explanation
The correct answer is intel 80286. The Intel 80286 was the first microprocessor used for home computers. It was released in 1982 and offered significant improvements over its predecessor, the Intel 8086. The 80286 introduced a 16-bit architecture and provided better performance and multitasking capabilities, making it suitable for personal computers. It was a popular choice for early home computers and helped pave the way for future advancements in computer technology.

### Bus dengan delapan penghantar, data dapat diteruskan dalam arah bolakbalik (lebar data 8 bit) yaitu dari mikroprosesor ke unit memori atau modul I/O dan sebaliknya adalah tipe data bus....

• A.

• B.

Bol Bus (bus-B)

• C.

Control Bus (bus-C)

• D.

Data Bus (bus-D)

• E.

Enrolment Bus (bus-E)

D. Data Bus (bus-D)
Explanation
The given passage mentions that data can be transferred in both directions between the microprocessor, memory unit, and I/O module. This indicates that there is a need for a bus that can handle bidirectional data transfer. Among the options given, the Data Bus (bus-D) is the most suitable because it is responsible for carrying data between the microprocessor, memory, and I/O devices. The other buses mentioned, such as Address Bus, Control Bus, Bol Bus, and Enrolment Bus, do not specifically deal with data transfer.

### Prosesor intel 386 merupakan contoh dari .....

• A.

Sistem komputer

• B.

Mikroprosesor

• C.

Komputer

• D.

RAM

• E.

ROM

A. Sistem komputer
Explanation
The Intel 386 processor is an example of a computer system. It is a central processing unit (CPU) that is designed to function as the main component of a computer system. The processor is responsible for executing instructions and performing calculations, making it a crucial part of any computer system. Therefore, the Intel 386 processor can be considered as an example of a computer system.

### Instruksi debug apa yang digunakan untuk melihat semua isi register setelah menjalani setiap satu baris instruksi ....

• A.

R

• B.

W

• C.

A

• D.

T

• E.

B

A. R
Explanation
The correct answer is "R". This suggests that the instruction is asking for the debugging instruction used to view all the contents of the register set after executing each instruction.

### Konversikan bilangan binnary 11110010 ke desimal adalah .....

• A.

242

• B.

243

• C.

240

• D.

256

• E.

265

A. 242
Explanation
The given binary number 11110010 can be converted to decimal by multiplying each digit by its corresponding power of 2 and adding them together. In this case, the calculation would be: (1 * 2^7) + (1 * 2^6) + (1 * 2^5) + (1 * 2^4) + (0 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0) = 128 + 64 + 32 + 16 + 2 = 242. Therefore, the correct answer is 242.
