Hasil konversi dari bilangan biner 0110011 ke bilngan decimal adalah …
Correct Answer
C. 51
Explanation
The given binary number 0110011 can be converted to decimal by using the place value method. Starting from the rightmost digit, each digit is multiplied by 2 raised to the power of its position. Adding up these products, we get the decimal equivalent of the binary number. In this case, the calculation would be: 0*2^0 + 1*2^1 + 1*2^2 + 0*2^3 + 0*2^4 + 1*2^5 + 1*2^6 = 0 + 2 + 4 + 0 + 0 + 32 + 64 = 102. Therefore, the correct answer is 51.

Apabila kita menjalankan banyak program dalam satu waktu , namun komputer bekerja dengan lambat, maka hardware yang perlu di upgrade adalah ….
Correct Answer
B. Memori
Explanation
If a computer is running multiple programs at the same time but is working slowly, the hardware that needs to be upgraded is the memory. This is because the memory, also known as RAM (Random Access Memory), is responsible for temporarily storing data and instructions that the computer needs to access quickly. When the memory is insufficient, the computer may struggle to handle the workload, resulting in slow performance. Upgrading the memory can increase the computer's ability to handle multiple programs simultaneously and improve overall performance.

Partisi untuk swap pada linux disarankan minimal adalah ....
Correct Answer
B. 2 kali memori computer
Explanation
The recommended swap partition size on Linux is at least twice the size of the computer's memory. This is because the swap partition is used as virtual memory when the physical memory (RAM) is full. Having a swap partition that is at least twice the size of the memory allows for efficient swapping of data between the RAM and the swap partition, ensuring smooth performance and preventing system crashes due to insufficient memory.
16.
Jumlah minimal partisi yang dibutuhkan oleh sistem operasi Linux adalah…
Correct Answer
B. 2
Explanation
The minimum number of partitions required by the Linux operating system is 2. This is because Linux requires at least two partitions: one for the root directory ("/") and another for the swap space. The root directory partition is where the operating system and all system files are stored, while the swap space partition is used for virtual memory. Having separate partitions for these purposes allows for better organization and optimization of system resources.

Correct Answer
C. 128 bit
Explanation
IPv4 uses a 32-bit format for addressing, allowing for approximately 4.3 billion unique addresses. On the other hand, IPv6 uses a 128-bit format, which provides a significantly larger address space. This allows for approximately 340 undecillion unique addresses, ensuring that the growing number of devices connected to the internet can be assigned a unique IP address.
18.
Jika kita mempunyai IP class C, dengan subnet mask 255.255.255.192, berapa jumlah host/subnetnya ....
Correct Answer
D. 62
Explanation
The given subnet mask 255.255.255.192 indicates that there are 6 bits reserved for subnetting. With 6 bits, we can have 2^6 = 64 possible subnets. However, since two subnets (all zeros and all ones) are reserved for network and broadcast addresses, the number of usable subnets is 64 - 2 = 62. Therefore, the correct answer is 62.

Fungsi kecil dari router yang gunanya menggandakan IP address sehingga perangkat yang ada di belakangnya bisa mengakses jaringan Internet adalah ....
Correct Answer
A. NAT
Explanation
NAT (Network Address Translation) is a small function of a router that duplicates IP addresses, allowing devices behind it to access the internet. NAT translates private IP addresses used within a local network into a public IP address that can be recognized and routed on the internet. This allows multiple devices to share a single public IP address, conserving the limited supply of IPv4 addresses. NAT also provides a level of security by hiding the internal IP addresses of devices from external networks.
21.
Untuk menghubungkan hub dengan switch lainnya digunakan kabel ....
Correct Answer
D. Crossover
Explanation
To connect a hub with another switch, a crossover cable is used. A crossover cable is designed to connect two devices of the same type, such as two switches or two hubs, without the need for a crossover adapter. It allows the transmit (TX) signal of one device to connect to the receive (RX) signal of the other device, ensuring proper communication between them. This is different from a straight cable, which is used to connect devices of different types, such as a switch and a computer.

Untuk menerjemahkan IP ke nama domain dibutuhkan ....
Correct Answer
D. DNS server
Explanation
To translate an IP address into a domain name, a DNS server is required. A DNS server is responsible for resolving domain names into their corresponding IP addresses. When a user enters a domain name in a web browser, the DNS server translates it into the associated IP address, allowing the user to access the desired website. Without a DNS server, it would be impossible to navigate the internet using domain names, as IP addresses are the actual identifiers used by computers to communicate with each other.

Komputer yang bertugas menyimpan informasi halaman web yang pernah diakses sebelumnya adalah …
Correct Answer
E. Proxy Server
Explanation
A proxy server is responsible for storing and retrieving web pages that have been previously accessed. It acts as an intermediary between a user's device and the internet, allowing the user to request web pages through the proxy server. When a user accesses a web page, the proxy server stores a copy of that page. If the user requests the same page again, the proxy server retrieves the stored copy instead of fetching it from the original web server. This helps in improving performance, reducing bandwidth usage, and providing caching capabilities. Therefore, a proxy server is the correct answer for the given question.

Suatu sistem yang memungkinkan nama suatu host pada jaringan komputer atau internet ditranslasikan menjadi IP address disebut …
Correct Answer
E. DNS
Explanation
DNS stands for Domain Name System. It is a system that translates domain names (such as google.com) into IP addresses (such as 172.217.9.14) so that computers can communicate with each other on the internet. DNS acts like a phone book for the internet, allowing users to access websites and other resources using easy-to-remember domain names instead of complex IP addresses. Therefore, DNS is the correct answer because it enables the translation of host names into IP addresses.
