How it Works and Complete Types of Computer Printers

Silahkan sesuaikan nada chord dengan suara anda

Computer Science - A printer is a piece of hardware that is connected to a computer and has the function of printing text, images and other displays from the computer onto paper or similar media. The term known for printer resolution is called dpi (dots per inch). What this means is the number of dots in an area of ​​1 inch. The higher the resolution, the better the resulting print. On the other hand, if the resolution is low then the print results will be bad/not good. 

HISTORY OF COMPUTER PRINTER
Printing techniques were implemented simply in China in the 14th century. Chinese innovation has succeeded in creating ink and block printing which have had a major influence on the writing tradition. However, the development of printing techniques in China was not as great as the developments that occurred in Europe. This is because the Chinese alphabet has thousands of specific ideograms, which are very difficult to implement on a typewriter. As a result, there has been almost no significant change in terms of production efficiency in China as has occurred in Europe.

In the early 1950s, there was very rapid cultural development in Europe which created the need for a fast and cheap written document production process. It was Johannes Guternberg, a German goldsmith and entrepreneur, who succeeded in developing printing machine technology which revolutionized printing techniques. Printing itself was perhaps the most important invention of the last millennium, although its impact on the global economy was not that great. The invention of the printing press allowed the Bible to become the first mass-produced book.

Technology - Computer - Explantation of SSD - SSD stands for Solid State Drive or Solid State Disk, is a data storage device that uses a series of ICs as memory used to store data or information.

As an analogy, we may be familiar with USB Flash Drives or USB Thumb Drives or USB memory sticks. An electronic device that we use to store data, which we often carry everywhere, which is plugged into the computer's USB terminal when we want to retrieve or save data.

SSD can be considered an advanced version of a USB Flash drive with a much larger capacity and functions as a replacement for the hard disk that is currently used in computer devices . So an SSD is an electronic device that functions to store data like a hard disk (HDD: Hard Disk Drive) but its construction is like a USB Flash Drive, which is composed of several ICs as memory.

Like USB Flash Drives, SSDs do not have moving components inside them. Data or information is only stored in microchips. This is different from a hard disk which has a mechanical arm that moves back and forth to write and read data on the magnetic disk. This difference makes SSDs work much faster than hard disks.

13 Effective Ways to Make Your Laptop/Computer Last Longer

Silahkan sesuaikan nada chord dengan suara anda

Techlnology - Computer - Today's technological developments grow so fast and are increasingly difficult to predict, in just a matter of years, various creations and discoveries immediately color our activities until they are able to fulfill most of our daily needs. One of them is a computer /laptop which is also an inseparable thing in it.

However, the use of laptops/computers that do not comply with the instructions for use is often a crucial problem whose handling is rarely known by users, and this is of course a special concern for computer angels out there who voluntarily want to share knowledge about ways and tips to maintain laptops/computers. Your computer can be durable and long-lasting.

OK, without further ado, here are 13 effective tips to ensure that your laptop/computer is durable and long-lasting which we quoted from  https://blogger-sidrap.blogspot.com  :

1. Don't play heavy games for too long.
Continuously playing heavy games is the most common cause of laptop damage. If you just play Farm Frenzy, you want to play until your eyes start to cry, there's no problem. The problem is if you use it to play heavy games, such as GTA V, Watch Dogs, etc. for long periods of time. I have limited specs, I'm forced to play heavy games, it takes a long time to play. Poor laptop. So, what happened? The laptop will overheat. Where if this is allowed to continue to happen, it will cause damage to the laptop hardware.

2. Keep it away from anything wet.
Laptops are electronic items. So yes, we are very anti-water, especially water that contains minerals. The problem is that if it is exposed to water that contains minerals, it will corrode certain parts. If there is a lot of corrosion, your laptop will be damaged. The serviceman will raise his hand. Therefore, when using a laptop, keep it away from 'wet' items. I'm afraid that the wet water will spill, hit the laptop, and the water will get into the inside. It looks trivial but is very dangerous for the condition of the laptop.

3. Don't use it on a mattress.
This is a habit for many people. Placing a laptop on a mattress while in use can hinder air circulation inside the laptop. As a result, the internal hardware will overheat and as I said earlier, it could result in burnt out. That's because when you use your laptop on a mattress or in places that are not flat (which prevents air from escaping), the hot air produced by the laptop cannot escape and interferes with the performance of the laptop's hardware itself and can damage the hardware. damaged.

I don't know how to avoid using it on the mattress permanently. Because I myself also like this. The thought of "just once in a while" becomes my grip every time I use the laptop on the bed. But if this "one-time problem" happens repeatedly it will also damage the laptop.

4. Don't put heavy items on the laptop.
Some people are used to putting items on laptops that are idle. Starting from paper, pencils, books, cellphones, tablets, etc. The habit of storing things, especially heavy ones, means you will have to deal with heavy things later. Most likely what is damaged is the screen. If you frequently put heavy items, your desktop will change to a dark theme.

If you've changed it to dark themes, return it to the expensive default. The costs vary, depending on the laptop brand. If the MacBook is damaged, that's fine. If the work is easy, it's better to just buy a local netbook, which costs 700 thousand.

5. Don't move the laptop while it's on
Without realizing it, we are used to moving laptops with the condition still on. Usually we do this when we want to show something to someone, for example showing the results of our work to a boss who is quite close. So, why can't it be like this? If the laptop is on, the hard disk will definitely be on too. The hard disk is spinning. So, when the hard disk disk rotates, if you move it, the disk will definitely change its tilt.

And of course there will be scratches on the hard disk disk. As a result, the hard disk will experience bad sectors, namely a significant decrease in read/write speed. All processes will be slow. And if you do things like that regularly, then it's just a matter of time before your laptop gets damaged.

6. Clean the laptop screen regularly.
Apart from the interior, the screen also needs to be cleaned. The thing is, when you use a laptop, one of the things we look at the most is the screen. It's impossible for us to use a laptop, not focus on the screen but instead focus on something else, the power button for example. If the screen is dirty, our work will definitely not be comfortable. Even if the dust on the screen doesn't colonize, it still needs to be cleaned. The way to do this is to wipe the screen, just use a tissue, a regular tissue or a wet tissue, not another tissue.

Apart from making it comfortable to look at, cleaning the screen prevents dust from getting lost every day. There might even be spots on the screen and that will interfere with use. When it comes to cleaning your laptop screen, it's best to clean it at least once a week. But if it hasn't been a week and your laptop screen is already dusty, just clean it with a wet tissue.

7. Don't browse and download carelessly.
Everyone hates viruses or malware. What is called a virus is definitely annoying, depending on the level of intent of the creator. If it's just for fun, it's not that dangerous. But what if the intention was to rob? It's like a virus that locks and makes all files captive and asks for a certain amount of money if you want to unlock it.

It turns out that the viruses on the computer mostly come from obscure sites that we access. The site will transfer files (viruses) to visitors' computers invisibly. For this reason, every time you surf the internet, make sure the antivirus is on and can be used. This antivirus will warn us if the site we want to access is dangerous. Even if we continue, the antivirus will prevent the magical download.

8. Don't let the battery reach 0%
I said above, use a laptop like normal people use it. If people use a laptop that is not normal, they will usually avoid shutting it down before the battery reaches 0%. This should not become a tradition that we continue to do. Using the laptop until it turns off at 0% will reduce battery life. What used to be able to last up to 4 hours, due to frequent use it only lasts up to 1 hour. It also interferes with work later. Avoid using a laptop until 0%. Try to turn it off immediately before the battery power reaches 20%, so that the battery lasts longer.

9. Pay attention to laptop temperature.
Anything that is connected to electricity will definitely increase the temperature. Likewise with laptops. If the laptop is used for a short time, the laptop engine (hardware) will start to heat up. The longer it gets hotter, the more it rumbles. The nominal laptop temperature depends on the situation and conditions. How to use it, place it on a mattress or on a fan that is lying on. Laptop is used for Photoshop or just Ms. Paint. Used to play Virtua Cop or play GTA IV.

It's up to you what you want to use the laptop for and where you put it. The important thing is, don't let the laptop temperature get hotter than usual, or it might feel very hot. If it's like this, it's better to just turn it off straight away. I'm afraid that if I leave it, the hardware will burn, because of that heat.

10. Keep away from sunlight.
Not only laptops, it is actually not recommended to use all electronic devices under hot sunlight, especially during the day. The reason is clear, so as not to damage the hardware. Look, electronic devices obviously contain electrons, electric current, and definitely have a temperature (can increase the temperature). So, if the device itself already contains heat, what if you add heat from outside? Moreover, sunlight?

The sunlight was fierce. Even human skin can be damaged by too much sunlight. Especially laptops. So, avoid direct sunlight. For example, this is in a wifi corner, or anywhere in the open. The place we want to sit is exposed to sunlight. My advice is it's better to just sit somewhere else.

11. Keep away from food and drink.
It's best to play while snacking on your laptop. It's not wrong. But if you eat snacks, be careful, don't make a mess. It is feared that the snack crumbs that resulted from the failure to bite will get between the keyboards. Even though this isn't that big of a problem, it's still annoying. Yes, if it's a key that's rarely used, like F6, "`", or a key that has a spare like shift, ctrl, and alt.

What if it was the letter keys that were hit? Quite annoying. We will be bothered by copying and pasting letters that cannot be pressed from other places. Therefore, it is better for you to use a keyboard protector to protect the keyboard on your laptop so that if your laptop comes into contact with food, your keyboard can still be safe and protected so that you can type comfortably on the keyboard.

12. Install only the necessary software.
Sometimes, large storage makes us forget the purpose of buying a laptop. Those who initially bought a laptop were used to learn programming, where the software only needed to code websites, for example a web server, IDE, browser, and several others. Since there is still a lot of storage remaining, it can be a mistake. Install applications that are not important. Not very important, but installed. Only used once, after the installation process. After that it was never used again, or even forgotten.

This application will burden the running process. As a result, when we run an application, whatever it is, it will feel slower. For this reason, from now on delete all applications that we rarely use, that we don't need.

13. Limit Startup Applications Startup applications
, running applications, start automatically when the PC boots and enters Windows. This startup feature can sometimes improve the UX. But it can also affect laptop performance. Especially if the specs are mediocre. Usually, these startup applications are invisible, but run in the background. This will speed up the process of opening the application. But on the other hand, the boot process will be burdensome and will take a little longer than usual. Yes, it takes a while, because it is accompanied by opening a startup application. And usually there is not just one startup application, of course the process is carried out together.

Hopefully this is useful...

Technology - Computer Science - There is a classic saying that says "Prevention is better than cure" or "Prepare an umbrella before it rains". The expression above is not just an expression, no one can predict when and where your computer /laptop will be hit by a disaster, be it a virus attack or hardware damage that can cause your computer datato become damaged and unsalvageable. And one of the indications or signs that your laptop is at risk of data loss is "Computer/Laptop Frequently Hangs".

A computer that often hangs has the potential for a lot of damage, such as hardware damage, software damage, and other problems such as viruses. Computers are one proof of the rapid development of technology that is occurring today. Starting from computers with standard and functional sizes and specifications, to computers with thin, small sizes but with extraordinary performance, there are many in circulation today.

This is also supported by the development of network technology, which allows every computer to be connected to each other, even smartphones. However, even though we have high technology and impressive performance, it turns out that computer hang problems occur very often, even with computers with high specifications. At least, the cause of a computer hanging can occur due to two things, namely:

5 Levels of Hackers Based on Their Abilities

Silahkan sesuaikan nada chord dengan suara anda

Hackers News - The following are the levels in the world of hackers.

5. Lamer
They are people without experience & knowledge who want to become Hackers (wanna-be Hackers). They usually read or hear about Hackers & want to be like that. Their computer use is mainly for playing games, IRC, exchanging private software, stealing credit cards. Usually hacking uses trojan, nuke & DoS software. Usually brag via IRC channels etc. Because there are many drawbacks to reaching elite, in their development they will only reach the level of developed kiddie or script kiddie.

4. Script Kiddie
Like developed kiddie, Script Kiddie usually carries out the activities above. Like Lamers, they only have very minimal technical knowledge of networking. Usually it can't be separated from the GUI. Hacking is carried out using trojans to scare & make life difficult for some Internet users.

Silahkan sesuaikan nada chord dengan suara anda

Technology - World Hackers - Basically Hackers are Good "Hackers are a Good Human" . The evil and heartless are the rulers who oppress their people and impoverish the mindset of the younger generation with lies and misleading deceptions. Quoted from the Computer Angel Forum page , one of the best voluntary communities in Eastern Indonesia which is famous for its principle of helping without compensation, especially for repairing computer problems, both systems and hardware.

According to Andi AM, founder of Angel Kompiter IT , there are three hacker groups that are most feared in the world, both in terms of their history of actions and their toughness when acting to paralyze their targets.

1. ANONYMOUS - Social movements
The first best hacker group is Anonymous, a group that moves more frequently socially and is the most respected in the world. This hacker group does not have a clear structure, its name is also Anonymous.

This group is also often associated with Black-hat Hackers, an anonymous group (without a name) who often appear with the attributes of a Guy Fawkes mask in the film 'V for Vendetta'. They have attacked several large websites such as the FBI, Department of Justice, Universal Music Group, # PayPal, MasterCard, Sony PlayStation Network and other big sites for obvious reasons.

Hackers News - Technology - How are you Dumay friends, this time the admin will share a little about the activities of hackers who are famous for their skills in hacking or taking over and even destroying their target sites. Yes... Recently, we have often encountered hackers' actions on various sites which are considered to be detrimental to several parties. The effect of this displeasure ultimately led to attacks on target sites that were considered problematic.

Apart from all that, whether behind the attack there is another motive or just wanting to test a site's defenses, this is very common, so to anticipate serious damage from hacker attacks, of course the opponent must also be equal. Is this worthy of being categorized as an operation by hackers or crackers, we are all confused, because hackers and crackers are sometimes misunderstood, and quite a few even consider both to be "Evil"..

Well... here the admin shares the 2 most dangerous types of hacker attacks and scary in the world according to the Computer Angel Forum..

What is Quantum Computing (Quantum Computing) Future Technology?

Silahkan sesuaikan nada chord dengan suara anda

Technology - What is Quantum computing?
In general, Quantum Computing or Quantum Computing is a computing technology that has the potential to provide superpowerful computers capable of solving difficult problems in a matter of seconds. In the fields of science, health, and finance, quantum computing can accelerate discovery and innovation.

Quantum computing can be classified as a multidisciplinary field consisting of aspects of computer science, physics, and mathematics that utilize quantum mechanics to solve complex problems faster than classical computers. The field of quantum computing includes hardware research and application development. 

Quantum computers are able to solve certain types of problems more quickly than classical computers, by exploiting the effects of quantum mechanics, such as superposition and quantum interference. Some applications where quantum computers could provide such speed improvements include machine learning (ML), optimization, and simulation of physical systems. Use cases could ultimately be portfolio optimization in finance or simulation of chemical systems, solving problems that are currently impossible for even the most powerful supercomputers on the market.

Quantum Computer Components And Working Principles (Future Technology)

Silahkan sesuaikan nada chord dengan suara anda

Technology - What are the principles of quantum computers?
In general, a quantum computer is a super powerful computer that can solve difficult problems in a matter of seconds. In the fields of science, health, and finance, quantum computing can accelerate discovery and innovation.

Quantum computers work using quantum principles. Quantum principles require a new dictionary of terms to fully understand, terms that include superposition, entanglement, and decoherence. Let us understand the principles below.
  • Superposition Principle
    Superposition states that, like waves in classical physics, you can add two or more quantum states and the result will be another valid quantum state. Conversely, you can also represent each quantum state as the sum of two or more different states. This superposition of qubits gives quantum computers their inherent parallelism, allowing them to process millions of operations simultaneously.

  • Principle of Entanglement
    Quantum entanglement occurs when two systems are so closely connected that knowledge of one system gives you direct knowledge of the other system, no matter how far apart they are. A quantum processor can draw conclusions about one particle by measuring another particle. For example, a quantum processor can determine that if one qubit spins up, another will always spin down, and vice versa. Quantum entanglement allows quantum computers to solve complex problems more quickly.

    When a quantum state is measured, the wave function collapses and you measure the state as zero or one. In this known or deterministic state, the qubit acts as a classical bit. Entanglement is the ability of a qubit to correlate its state with other qubits.

  • Decoherence Principle
    Decoherence is the loss of quantum states in qubits. Environmental factors, such as radiation, can cause a qubit's quantum state to collapse. A big engineering challenge in building quantum computers is designing features that try to delay state decoherence, such as building special structures that protect qubits from external fields.
