TLJ KD 3.1 MEMAHAMI RAGAM APLIKASI KOMUNIKASI DATA

Memahami Ragam Aplikasi Komunikasi Data

• Pengertian Komunikasi Data

          Komunikasi Data adalah proses pengiriman dan penerimaan data/informasi dari dua atau lebih alat yang terhubung dalam sebuah jaringan.

• Komponen-komponen Komunikasi Data:

        - Pengirim : Piranti atau perangkat yang mengirimkan

        - Penerima : Piranti atau perangkat yang menerima

        - Data : Bahan/informasi yang dipindahkan atau dikirimkan

        - Media Pengiriman : Media yang digunakan untuk mengirimkan data

        - Protokol : Aturan yang menyesuaikan atau menyelaraskan hubungan

• Komunikasi dibagi menjadi 3 bagian, meliputi:

1. Komunikasi Audio
2. Komunikasi Video
3. Komunikasi Audio Video

• Pengertian Komunikasi Audio

          Komunikasi Audio adalah bentuk komunikasi yang dilakukan dan terjadi melalui media audio atau suara.

• Contoh Komunikasi Audio:

1. Telepon
   
2. Radio
   

Keuntungan Komunikasi Audio:

1. Harga murah dan variasi program lebih banyak
2. Sifatmya mudah untuk dipindahkan
3. Dapat digunakan bersama-sama dengan alat perekam radio
4. Dapat merangsang partisifasi aktif pendengaran

Kelemahan Komunikasi Audio:

1. Memerlukan suatu pemusatan pengertian pada suatu pengalaman yang tetap dan tertentu, sehingga pengertiannya harus didapat dengan cara belajar yang khusus.
2. Media Audio yang menampilkan simbol digit dan analog dalam bentuk auditif adalah abstrak sehingga pada hal-hal tertentu memerlukan bantuan pengalaman visual.
3. Karena abstrak, tingkatan pengertiannya hanya bisa dikontrolmelalui tingkatan penguasaan perbendaharaan atau kata-kata atau bahasa saja.
4. Media ini hanya dapat melayani orang yang mempunyai kemampuan berfikir abstrak.
5. Penampilan melalui ungkapan perasaan atau simbol analog lainnya dalam bentuk suara harus disertai dengan perbendaharaan pengalaman analog tersebut pada si penerima.

• Pengertian Komunikasi Video

          Komunikasi Video adalah bentuk komunikasi yang dilakukan dan terjadi melalui video atau visual.

• Contoh Komunikasi Video:

1. Televisi
   

Keuntungan Komunikasi Video:

1. Dapat digunakan untuk menyampaikan informasi tanpa harus bertemu penerima.
2. Dapat digunakan untuk berkomunikasi dengan orang lain tanpa mengenal waktu
3. Dapat digunakan sebagai media pembelajaran.

Kelemahan Komunikasi Video:

1. Sebagaimana media audio-visual yang lain, video juga terlalu menekankan pentingnya materi ketimbang proses pengembangan materi tersebut;
2. Pemanfaatan media ini juga terkesan memakan biaya tidak murah
3. Penanyangannya juga terkait peralatan lainnya seperi videoplayer, layar bagi kelas besar beserta LCDnya, dan lain-lain.

• Pengertian Komunikasi Audio Video

          Komunikasi Audio Video atau Komunikasi Audio Visual adalah dapat berkomunikasi secara Real-time yang datanya dapat berupa Audio dan Visual.

• Contoh Komunikasi Audio Video:

          Whatsapp, Skype, Google Duo.

Whatsapp Video Call

Keunggulan Komunikasi Audio Video: 

• Memperjelas penyajian pesan agar tidak terlalu bersifat verbalistis (dalam bentuk kata-kata, tertulis atau lisan belaka)
• Mengatasi perbatasan ruang, waktu dan daya indera.

Kelemahan Komunikasi Audio Video : 

• Terlalu menekankan pentingnya materi ketimbang proses pengembangannya dan tetap memandang materi audio-visual sebagai alat Bantu guru dalam mengajar.
• Terlalu menekankan pada penguasaan materi dari pada proses pengembangannya dan tetap memandang materi audio visual sebagai alat Bantu guru dalam proses pembelajaran. Media yang beoriantsi pada guru sebernarnya
• Media audio visual cenderung menggunakan model komunikasi satu arah.
• Media audio-visual tidak dapat digunakan di mana saja dan kapan saja, karena media audio-visual cenderung tetap di tempat.

FUNGSI DAN TUJUAN KOMUNIKASI DATA:

1. Efisiensi pengiriman data dlm jmlh besar (tanpa kesalahan dan ekonomis)
2. Memungkinkan penggunaan sistem komputer & peralatan pendukungnya dr jauh (remote computer use)
3. Sistem komunikasi data memungkinkan orang dan bisnis yang mempunyai lokasi geografi berlainan dapat saling berkomunikasi.
4. Mendukung manajemen dlm hal kontrol krn memungkinkan penggunaan sistem komputer secara terpusat maupun tersebar
5. Memungkinkan kemungkinan pengelolaan data dan pengaturan data yg ada dlm berbagai macam sistem komputer

Article About VIVO V11 Pro || Information Of Smartphone

Article About VIVO V11 Pro || Information Of Smartphone

Pick up the new Vivo V11 Pro, and the first thing you notice is a sleek design. And it is not just the looks, but the fact that it also packs in a lot of interesting features which we will explain in detail. Does all that make the V11 Pro worth your money? After all, this has a lot of competition at the Rs 26,000 price point, and consumers are spoilt for choice. The VIVO V11 Pro comes with a noticeable screen size of 6.41 inches. This is the first V-series phone to get a 'waterdrop' notch with in-screen fingerprint option. It sports a super AMOLED screen which is efficient and looks good. The in-display fingerprint display is visible very prominently as soon as you will open the device and is highlighted with a circular display.


Although the phone is big in size and weighs 156 gm, it is surprisingly light and not as heavy as the premium offering by the company - the Nex. The body is curvy on the edges which give it the smoother finish. V11 Pro comes with a 3.5mm headphone jack and supports dual sim. The speakers and the charging port at the bottom are quite similar so nothing new on the button layout front. What we find missing in the phone is the water and dust resistant body so you have to be extra careful on that front.

Once you set up the in-screen fingerprint sensor, all you need to do is press your finger down on the display and it should unlock the phone. During our extensive use of the phone, the in-screen fingerprint recognises the finger most of the time, but the key to it is placing your finger properly with a slight pressure on the screen. It is a little disconcerting to press down hard on your phone's display, but that is what this technology demands. In contrast to that, the facial recognition feature works pretty fast, just raise the phone to the eye level and its all done. The response time is quite minimal and it worked accurately for us.

The camera is an important and major highlight of the Vivo V11 Pro. It comes with a 12 MP+ 5MP dual rear camera setup. The front camera has a massive 25 MP super-high-resolution sensor. Pictures clicked during the day captures are fine details along with good colours. You get a lot of options and different modes such as panorama, Doc, Professional and AI Face Beauty to select from. AI Face beauty mode Every time you will open the camera to click pictures you will see AI Face beauty as the default mode. the AI low light mode algorithm has been optimized, and it takes multiple images at different exposures and combines them for enhancing brightness in low light conditions while retaining the details and bright picture. The videos recorded on the V11 are jerk free and you get options like the Slow motion and time lapse along with face beauty feature. Though one feature which we missed is the electronic stabilisation.

The V11 Pro packs a 3400 Mah battery which is non-removable. it is equipped with what Vivo calls the dual-engine charging. This charges up the large 3400mAh battery quite quickly. In terms of battery life, we got over a day and a half of backup on our regular usage, which is good considering a 6.4-inch screen.

The Vivo V11 Pro tries its best to deliver everything a casual user seeks in a mid-range smartphone, priced at 25,990. It has shortcomings, such as a sluggish fingerprint sensor, but overall the V11 Pro offers a good mix of features and performance that cannot be ignored.Thanks to the Qualcomm Snapdragon 660AIE Octa-core processor the V11 Pro offers decent overall performance. The processor gets the required support from the 6 GB RAM which the phone is offering. We tried a lot of games and apps for a considerable amount of time and not once did the phone show any signs of lagging. We didn't face any heating issues during our extensive use of the phone either. The VIVO V11 comes with a 64 GB inbuilt storage which is expandable upto 256 GB via a microSD card. From the 64GB of the inbuilt storage, you will get around 46 GB for your apps, media content and files.

Article About SAMSUNG GALAXY A7(2018) || Information Of Smartphone

Article About SAMSUNG GALAXY A7(2018) - Information Of Smartphone

Samsung Galaxy A7 (2018) is reportedly receiving its stable Android 9.0 Pie update in Russia. The new update is said to bring One UI on top Android Pie and come along with the February 2019 security patch. The Galaxy A7 (2018) was launched with Android 8.0 Oreo along with Samsung Experience UX on top last year, though it received a beta update based on Android Pie-powered One UI last month. Recently, Samsung was found to have released the Android Pie update for the Galaxy A9 (2018) and Galaxy A8+ (2018). The South Korean company also brought a One UI beta update with Android Pie specifically for the Galaxy A6 (2018).

The Samsung Galaxy A7 is a phone that you might notice because of its looks, explore because of its display and buy because of its camera. That's the kind of balance that Samsung has tried to strike with their first triple camera phone.

From what we saw on paper, the Galaxy A7 (2018) looked like a phone that's made for everyone. And by everyone, we mean that it packs a decent set of hardware in a premium looking shell and a camera you can get creative with.

At its price, the 4GB RAM variant of the Galaxy A7 competes against the likes of the POCO F1, Honor Play, Nokia 7 Plus and Vivo V11 Pro. Among all the competing handsets, there's hardly any option that serves different consumer demands without any compromise.  For instance, the POCO F1 offers raw power, but the Vivo V11 Pro shines in the design and display department. Whereas, the Nokia 7 Plus offers the best software experience among all.
Key features
Three rear cameras
6-inch FHD Super AMOLED display
Looks like a flagship, performs like a mid ranger
The Samsung Galaxy A7 (2018) is the first Samsung phone to boast of a triple camera setup, and the second one in India after the Huawei P20 Pro. Of the three cameras, the primary is a 24-megapixel sensor with a f/1.7 aperture, the secondary is an 8MP sensor and ultra-wide lens with a f/2.4 aperture, and finally, there's a 5MP depth sensor with a fixed-focus lens and f/2.2 aperture. The highlight here is the 8MP sensor as it has a 13mm 'ultra-wide' lens with a 120-degree field of view.

It also has a big 6-inch Super AMOLED full HD (1080p) display, that's best in the league for multimedia consumption. The company also emphasizes on the Widevine L1 certification, which enables users to stream content in HD.

Design
Metal and glass design
micro USB charging
Flat surface
From the very first look, it's easy to guess that the Galaxy A7 is a Samsung phone. The quality of material and the precision of finish is seen on flagship phones like the Galaxy Note 9. Similar to its predecessor, the Galaxy A7 (2018) comes in a glass and metal sandwich design, but without any curves on the sides. It gets a rich-looking reflective glass surface on the rear, that shifts shades in different light.

Since it's back is all glass, it's a given that it's a fingerprint magnet and prone to cracking when dropped with an impact. But I have an instance to share. It was my first day with the Galaxy A7 and I accidentally slipped it on a marble flooring from a height of about three feet. The sound gave me instant chills, but to my surprise, it survived. While that doesn't qualify it to be called as a shatterproof phone, but I would still call it a sturdy and well-built handset.

A sturdy body-colored aluminum rim surrounds the body. It has rounded corners and curves to give it a pleasant in hand feel. Although, its big size makes it difficult to operate with one hand.

There's a welcome change in the design this time. After experimenting with the fingerprint sensor on their phones, Samsung finally put fingerprint into the power/lock key like Sony Xperia handsets. You don't have to make an extra effort to reach, as it falls right under the thumb while holding it with the right hand. The power button is still clickable, but you don’t need to press it to unlock the phone.

The triple camera placement is very subtle. The setup resides on the top left corner with a LED flash below it. We must say that Samsung does a great job at keeping the handsets void of any unusual camera protrusion. Even on the Galaxy A7, there's a very tiny bump despite the three cameras.

You can pick up the 64GB Samsung Galaxy A7 now for $459 or £309. No Australian release has been confirmed.

In addition to SIM-free options, the phone is available on contract for around £19 per month in the UK.

Key features
Three rear cameras
6-inch FHD Super AMOLED display
Looks like a flagship, performs like a mid ranger
Sporting a glass front and back coupled with a plastic frame, the Galaxy A7 2018 features a mix of mid-range and flagship materials.

It does however feature an impressive Super AMOLED screen, amongst the best you can get in this price range. The 1080 x 2220 resolution is perfectly respectable and the 6-inch size is big, without being overly cumbersome.

The A7 is running Android 8.0 Oreo; it’s a shame it didn’t get Android 9 Pie, the latest version of Google’s mobile operating system, although app support will still be excellent thanks to Google Play store support. It will get Pie, but no time-frame has been given by Samsung.

Design
Plastic and glass design
micro USB charging
Flat surface
Priced at the upper end of the mid-range spectrum, the A7 2018 is competing with the Huawei Mate 20 Lite, Motorola One and Nokia 7.1.

Like the competition, the Samsung A7 features a glass back and front. It looks good, but has a slightly hollow feel, so is bested by the beautifully designed Nokia 7.1 in this respect. The sides are also plastic and they feel it, further attesting to the phone’s mid-range positioning.

Still, at 7.5mm thin it’s slender, and the AMOLED screen tech separates it from the pack, while you have a good choice of color options, with the A7 available in black, blue, pink and gold. It’s a clean design, interrupted only by a couple of logos and a slight camera bump around the back.

Two volume buttons and a flat, recessed, easy to hit power button are on the right-hand side of the phone, while on the left is the SIM tray, with our dual-SIM version supporting two SIM cards and a microSD card.

The power button doubles as the fingerprint scanner, a design decision borrowed from Sony phones of old. While it’s not as quick as flagship fingerprint scanners, it works reliably, not even requiring a full press to unlock the A7 securely – and there’s also Face Unlock to work in tandem and get you into your phone fast.

Article About Xiaomi Black Shark || Information Of Smartphone

Article About Xiaomi Black Shark - Information Of Smartphone

Later we got the news that Xiaomi is working on a new ambitious project with a brand-new company that is also headquartered in China, Nanchang Black Shark Technology Co. Ltd. The project is the first smartphone smartphone compounding project which is claimed to be a true smartphone, designed to answer that need.

But what's interesting, Xiaomi said that some leaked photos of his Black Shark device were fake. The Redmi brand pembesut company itself has not revealed many things about the device in question. But recently a photo appears that looks more convincing, where it appears the back of a smartphone that is claimed to be the back of Xiaomi Black Shark.

The smartphone gaming fad is becoming massively popular and receiving a lot of attention from smartphone manufacturers. Early birds in the segment include Asus’ ROG which is a big name in the PC gaming community, ZTE’s Nubia, and Xiaomi-backed Black Shark. Xiaomi recently launched the much-improved Black Shark 2, powered by Snapdragon 855, effectively making it the gaming phone with the highest processing power. Its affordable flagship pricing is the cherry on the cake.

The Black Shark 2 has many quirks that resonate with games, including multiple RGB lights, detachable Nintendo Switch-like controllers, and a dedicated switch to launch “Shark Space” – a deep clean optimization mode so that all the resources are freed up and fed to games. But what is perhaps the most exciting part is the “Ludicrous” mode on the Black Shark 2 which results in robust gaming performance by the allocation of the smartphone’s total processing power to games.

Xiaomi was one of the first OEMs to jump on the gaming phone bandwagon back in 2017. The company followed it up with a direct successor last year, the Black Shark Helo, and could be set to continue down that part with another device soon, in the Black Shark 2. The Black Shark 2 surfaced on popular benchmark AnTuTu a few days ago, revealing a few details of the gaming phone.

Going by the AnTuTu listing, the Black Shark 2—ambitiously codenamed "Skywalker"—will be powered by a Snapdragon 855. Xiaomi already has a Snapdragon 855-powered device, the Mi 9, and any other SoC appearing on the Black Shark 2 would be the real surprise. The listing shows the device running on Android 9.

On board is 8 GB of RAM and 128 GB of storage. The Black Shark Helo featured 10 GB of RAM, so that’s the first real surprise. It’s possible, however, that the device shown on AnTuTu is the base model of the Black Shark 2. We expect the top of the line model to ship with up to 12 GB of RAM, and it's not a baseless expectation either, since a Black Shark 2 unit with 12 GB of RAM actually appeared on Geekbench a short while ago.

Finally, the overall AnTuTu score awarded to the unit is a handsome 359,973. That’s a bit below the Mi 9’s score of 371,849 but this is just a test unit and we expect production units to perform better.

The Xiaomi Black Shark 2 is expected to be unveiled on March 18, which means we won’t have to wait much longer for it.
