Definition And Function RAM on Your Computer and Smartphone

Perhaps for those who frequently use the gadget, said RAM often you hear or you encounter. When buying a device, often you also check how much RAM the device. So what exactly is meant by RAM and what does it do?
understanding RAM

RAM (Random Access Memory) is a device inside a computer or gadget that can access random memory quickly. RAM is sometimes also referred to as main memory in a device.

RAM ability to randomly access data enables faster data display. Additionally RAM can also store data on the device when the device is turned on and the data have not been stored on the hard drive. It can be said that the RAM is the fastest storage device in a computer than with other types of memory devices such as HDD or Hard Disk Drive and SSD or Solid State Drive.

However, another thing that distinguishes RAM to other storage devices is the stored memory is temporary and will disappear automatically if the computer or device is turned off.
Can be explained in general that when we open the program of transfer of data from the hard disk to the RAM, why? Because the data in RAM faster and more accessible compared with the data on the hard disk or memory. Accessing data from the RAM requires no lag time or time to wait. So the more RAM into a gadget the faster memory data or a program can be accessed.
In fact, the RAM capacity can be enlarged to increase the speed of a computer device or other gadgets such as laptops and smartphones.RAM function
A device must have a function in a gadget, as well as RAM. The main function of RAM, among others:1. Reading DataData stored in the hard disk will typically longer displayed because it could be said the hard drive is a storage device that works slowly.This is because the hard drive is stored a lot of data and it takes time to find them, especially if the data is fragmented. To reduce delays in a process of retrieval, once a file or data is first opened, the data will be read and stored in RAM temporarily so that the data will be more quickly accessed when the program is still running and the computer has not been turned off.As already explained earlier that the RAM to work very fast, even faster than the solid state drive so that the data is being read and re-opened in a program will still run and can be opened again quickly when moving from one program to another as long as the program does not closed.
2. Temporary Storage
In addition to reading the data, the RAM also serves as a temporary data storage when a program is running.

For example, when typing text in Microsoft Word or another program, then the words are written will be stored in the program even though storage is temporary and not permanent. By storing data temporarily in RAM, the program can run faster and responsive.

Given the nature of storage in RAM is temporary, do not forget to save the data in a format that is permanent for undesirable events, for example a power failure or other things can cause data to be lost and can not be accessed again.
RAM size

To check how much RAM in a computer, you can read the tutorial here. The amount of RAM will affect the performance or the speed of a computer.

If the computer is running slow, check the size of the RAM in the computer and if the entire RAM capacity is almost fully charged then add RAM or upgrade the RAM will be able to speed up the performance of the system in a computer device.

Adding RAM in a computer with a capacity of 1 GB or 2 GB would not be so pronounced if it is used to open several programs such as games, photos, videos and so forth. RAM can be accessed more quickly, but why computer or an entire system does not store the data in RAM? The main reason is because the size of the RAM of a gadget is always smaller than the size of the hard drive.

For example in a computer hard drive size can reach 10 TB of memory while the RAM in it usually only reaches a maximum of 8 GB, RAM capacity even Windows 8 Enterprise version can only reach a maximum of 512 GB.

This is the definition and function of the CPU and its components are that might not You Know

When buying a computer device normally someone would see the specifications first. We also often hear the term Pentium and some specifications such as quad-core Intel i7 3.5 GHz, and so forth. This term refers to the speed of a computer processor or called by the CPU.You are already familiar with the term CPU may have a clear idea of ​​understanding and the CPU function, but for those who do not know, it's good to learn it.understanding CPUCPU stands for Central Processing Unit is the hardware component of the hardware or the main data processor in a computer. CPU can be referred to as the computer brain of the CPU organizes all activities and running all applications or software programs included in it.Whatever it all matters relating to the process of the computer system either a trivial process will always be set by the CPU. For example, when you press the letter "H" on the keyboard while typing, the letter "H" will appear on the screen, the CPU was the one who allowed it to happen. Thus, in the absence of a CPU in a computer, the computer will not be able to do anything or the computer can not run the program.CPU also technically more commonly referred to as the processor, therefore the time to read and identify the actual specifications for the processor then you're reading the specifications of the CPU of a device.components CPUA CPU at least have a "processor" or a chip that is embedded in functioning in the process of computer calculations. However, rapid technological developments also allows a CPU has more than processor or also known as the "processor core".The terms we often hear today comes from the CPU technological developments, for example technology "dual core" in which a CPU has two processing cores, or quad core, which has four processing cores. A sophisticated CPU even have the technology with six (hexa-core) or eight processing cores (octo core).

Not only that, a sophisticated computer server can have more than one CPU with many processing cores inside.
CPU functions

As a major component in a computer, the CPU has several important functions. Among these functions are: 
 1. Fetching 
Fetching is a term used in computer science and is understood as a process of extraction or retrieval. In a computer, the data is stored in the hard disk on CPUs with an address. 
Likened data within the processor or CPU arranged in a set of addresses and when a program is executed the CPU will take data from the address stored in the component. 
2. Decoding
 In a system CPU, a program to be executed or to be executed, shall be in accordance with the code of instructions that will be translated so that the CPU can recognize it in binary instruction code. It can be concluded that the decoding is a process of translating a program into a language understood by the CPU. 
Decoding occurs in the CPU and all the programs running on the computer device to go through the process of decoding first. 
3. Executing 
When a program is executed then the CPU will execute the program. The point is that the CPU will do the one thing that is doing the calculations or calculations using a component therein called the ALU or Arithmetical Logical Unit. 
Component ALU itself is responsible for all the mathematical calculations and logic in the computer. Besides the function execution of a CPU is also meant as a process of moving data from one storage device to the other memory devices. 
4. Storing 
Storing or storing data is one of the other functions of the CPU. When someone uses a computer then he needs a device to keep it provisionally or permanently.If someone needs data quickly and temporarily save it then the CPU will store it in RAM while the data is permanently stored in the hard disk will be entered into. Both functions are performed and controlled entirely by the CPU.

To run these functions rely on the CPU not only the processor but also involves several other devices including hard disk, motherboard, RAM, floppy drive, sound card, USB port, VGA Card and so forth. All of the parts are arranged in such a manner and are connected to each other. The faster the CPU is working, the better the performance.

CPU speed is measured in Hertz, which means one operation per second, and is usually written in units of GHz or Giga hertz. 1 GHz CPU speed is defined as one million in performing operations in a computer. Do you now understand what is meant CPU in a computer and their functions?

How to Install Drivers Laptop or Computer for Beginner

As I explained in this article, so that hardware PC or laptop to function properly, you need to install drivers. These drivers are used to bridge the operating system with the hardware of your PC or laptop. Without the driver, it is impossible operating system can recognize and communicate with hardware such as a LAN, Chipset, VGA, and so forth.
To install the drivers on the PC, the most frequently used is DriverPack Solution. The program contains millions of drivers which will certainly be very helpful for computer users in their PC driver installation.Why DriverPack Solution?
I'm here there is no intention to promote this software. DriverPack Solution Because this is really useful for computer users, especially those who lay in the computer world. Suppose you just bought a new laptop, you definitely get a driver CD is not? After that you need to install one by one.
Well usually the drivers that are included in the CD out to date or old version of the driver. Maybe it would not be a problem for some people. Now the case that I often hear is the drivers CD is missing, do not quite understand how to install drivers and so forth. Therefore, DriverPack Solution is a very appropriate choice.The file size is very large ?
As I have said before that this program contains millions of drivers in their databases, so do not be surprised if the file size of the monster, hehehe. Besides the more up to date version you use, usually the larger the file size. Oh yeah, make sure you download the latest version because the database is far more drivers and up to date.How to use DriverPack Solution
Because the program has a .iso format, so to unlock it first make sure you've installed the software CD / DVD image file PowerISO or a tool such as DAEMON Tools.
1. First, start the program as usual.
2. You will see the initial appearance of DriverPack Solution as shown below. The version I use is veri that 'pretty' new. So as I said before, try using the latest version.

3. After the driver scanning process is completed, you will see the number of drivers to be installed. For example, on a laptop my sister there were 14 drivers will be installed. To install all the drivers, just click the Install button Automatically.

4. In the following steps, you please wait a few minutes. Old or not this process depends on how many drivers installed.

5. If the driver already installed all finished, you will see a screen like the image below. Do not forget to reboot / restart your PC after installing all the drivers completed.

That's how to install drivers or laptop computer with ease, even laymen who I think will be able to do it yourself. Suppose you prefer to download one by one driver on his official website, it's okay.

Not that I do not want to write about how to download drivers from the official website. Because each vendor how to download drivers laptop is definitely different. Therefore, I strongly recommend using this method to make it more simple and easy to understand.

Microsoft Gives You The Windows 10 Upgrade Whether You Want It Or Not!

Microsoft recently confirmed that it has been pre-loading Windows 10 installation bits onto devices whose owners have not "reserved" a copy of the operating system, let alone showed any interest in it at all. Naturally, this has upset some users of Windows 7 and Windows 8.1 with many complaining that the unsolicited downloads have caused them to exceed data caps from their internet service providers or seized storage space without their consent.

Microsoft released a statement acknowledging the downloads stating, "For those who have chosen to receive automatic updates through Windows Update, we help customers prepare their devices for Windows 10 by downloading the files necessary for future installation. This results in a better upgrade experience and ensures the customer's device has the latest software. This is an industry practice that reduces the time for installation and ensures device readiness."

If a Windows 7 or Windows 8.1 user has Windows Update set to the default option, which was recommended by Microsoft, that allows the operating system to download and install security and other bug patches automatically in the background then Microsoft will push the Windows 10 upgrade files to the drive.

This upgrade can range from over 3GB to almost 6GB and is placed in the hidden "$Windows.~BT" folder. This folder has long been a destination for Windows upgrades and the Windows 10 upgrade will remain here until the user expresses an interest in installing the operating system...at least that's what we hope.

Microsoft has been pre-loading the Windows 10 upgrade on systems since the end of July, though it was believed that the practice was limited to PCs whose users had accepted Microsoft's free offer and reserved a copy of the operating system through an app the company automatically installed back in the spring and early summer on nearly every single PC running Windows 7 Home and Windows 8.1 Home, and on many PCs running Windows 7 Professional and Windows 8.1 Professional.

Once the Windows 10 upgrade was downloaded to the device, the user was notified via the app that installation was ready. But this new scheme is completely different in the fact that the bits are downloaded to the PC, regardless of the fact that the user has not asked for the upgrade whatsoever. What's not surprising is the people who noticed this first were the ones with data caps mandated by their internet service providers, especially those who relied on cellular connection to the internet.

There is a particularly long thread on Slashdot that has several commenters claiming that they had exceeded their caps because Microsoft downloaded this massive update to their devices without their approval. One comment reads, "I had to travel recently, so I took a laptop with clean Windows 8.1 Pro install. At my destination, I purchased a SIM (they only had 1GB data packages) and put it into the 3G/Wi-Fi router I carry. I powered the laptop, connected to Internet via said router, checked a few things, then went away for a few hours. When I got back to the apartment, my data package (and Internet connectivity) was killed because Microsoft idiots decided to start downloading Windows 10 even though I have explicitly closed/rejected all the offers."

Other users did not appreciate the unwanted upgrade that landed on their limited storage space. Anyone with a 128GB SSD would be very unhappy if 5% of their storage capacity was suddenly occupied without their approval. Others wondered whether Microsoft would take the next logical step by either giving users notifications telling them to apply the installed upgrade or make the move of triggering the download automatically.

If they triggered the download automatically it wouldn't be much different from what they've already done with those users who accepted the free upgrade and reserved a copy. It is also possible that a lot of users on the receiving end of the notifications would approve of the upgrade or even appreciate the fact they didn't have to wait a long time for the download to complete. However, if Microsoft downloaded the update without consent (again) then the people may very well grab their torches and pitchforks.

IBM Creates A Limitless Linux

With significant drivers expanding the mission critical applications in the industry, it's no surprise that Linux is the fastest growing operating system in the business. Speed, agility, a unified development environment and cost are all factors to this success. In addition to that, Linux's quality has advanced in recent years with mobile driving an increased focus on this platform. IBM has a lot of eggs in this basket, pushing its z Systems platform to take advantage of this trend and provide the strongest large scale offering around. IBM is convinced that they can expand their capability by taking Linux to new heights and are doing so by announcing the expansion of their coverage. Customers have begun wanting IBM to take Linux and give it the same focus as the company's most capable systems, and that's exactly what IBM is doing.

IBM's LinuxOne Portfolio is designed to provide a selection of Linux distribution of its choosing and with the scale and support you would expect from IBM's most powerful systems, like the z System. In addition to that, there are two other offerings, both of which are named after penguins. These two systems are known as the LinuxONE Emperor and the LinuxONE Rockhopper. Emperor is the premier offering, providing the greatest flexibility and scalability along with performance and trust for business-critical Linux applications. Emperor also has the greatest capacity range and no top end, meaning it can be expanded whenever and however you need to. Rockhopper is the entry system that starts much smaller than Emperor and provides a solution for a smaller company or unit.

Both of the systems allow you to choose your distribution, hypervisor, runtime, management tools, your choice of databases, and your choice of analytics. There are other coverages on hypervisors as well, including PR/SM. z/VM, and KVM. Languages include Python, Pearl, COBOL, Java, and Node.js. On the management side, we have WAVE, IBM Cloud Manager, OpenStack, Docker, Chef, Puppet, and VMware vRealize Automation. In terms of databases, there's Oracle, DB2LUW, Maria DB, MongoDB, and PostgreSQL with analytics include Hadoop, Big Insights, DB@BLU, and Spark. The range of offerings is also pretty good, including single platform, multi-platform, on premise, off premise, and multiple mixed cloud environments with a common toolset.

When it comes to pricing, things are pretty flexible. There's a Pay-Per-Use model with no upfront payment needed, a fixed monthly or quarterly payment, and variable costing that scales based on usage. A second pricing model uses a 36-month fixed lease with a 36-month usage contact and a right to return after 1 year. The final payment style is a Pre-Core rental model that allows you to order what you need when you need it, add licenses as needed, decrease licenses as needed or cancel with a 30-day notice.

Scale out and up supports up to 8 thousand virtual servers in a single system along with tens of thousands of containers, tens of thousands of concurrent users, and the ability to run test, development, and production in a single system. There is a significant focus on speed here as IBM has included its fastest processor, biggest I/O pipe, up to 10TB of memory, and 4 levels of cache, all of which brings you a sub-second end user response time at full load. The platform is designed to run at 100% utilization and to spin containers and virtual servers in a matter of minutes, automatically provide physical resources as needed in seconds via automatic resources provisioning and reallocation.

IBM testing has shown that it can handle up to 30 billion RESTful web interactions per day with up to 350,000 database read and writes per second. This is twice the performance of competitors for any NoSQL database, along with the longest single DB node. This assists in avoiding costs, complexity, and overhead of sharding.

This is Linux without limits. The Open Mainframe Project is a key element in the effort and it is being pushed forward by the Linux foundation in order to drive capabilities and growth. IBM is showing a commitment to driving this project with a lot of funding and company resources. This includes IBM Linux Technology Centers, Open Source Community Contributions, Academic Initiative and Training Programs, and open access to Mainframe community clouds. Members of this project include CA, CompuWare, BMC, Marris College, and the University of Washington.

IBM is pulling out all the stops here and this is definitely one of the most significant moves by the company in the past 10 years. IBM is enabling its centers worldwide to port, test, and benchmark key applications with free access to the Mainframe Community Cloud for developers and students across a plethora of top-tier universities. IBM definitely sees its future tied closely to Linux and a score of students coming from educational institutions and is focused on ever more mobile, flexible, applications.

New Solid-State Batteries From Samsung/MIT Could "Last A Lifetime"

Batteries. We need them for almost everything we use. They're in our laptops, our smartphones, our video game controllers, our remotes, and anything we use that is now wireless. But the one thing wrong with batteries in today's world is that they are finite. Eventually, they will run out of power and there's not a whole lot we can do about that. Or is there?

Researchers have recently developed a new material for a basic battery component that, according to them, will allow almost any battery indefinite power storage. This new material, known as a solid electrolyte, could increase battery life as well as battery storage capacity and safety as liquid electrolytes are the leading cause of battery fires.

The standard lithium-ion batteries that we use today use a liquid electrolyte. This liquid electrolyte is an organic solvent that has been known to overheat and cause fires in things like cars, commercial airliners and even smartphones. With a solid electrolyte, there is absolutely no safety problem whatsoever.

According to Gerbrand Ceder, a professor of materials science and engineering at MIT and one of the main researchers on the project, "You could throw it against the wall, drive a nail through it - there's nothing there to burn." In addition to that, a solid-state electrolyte will have virtually no degradation, which means that such batteries could last through "hundreds of thousands of cycles," Ceder continued.

Organic electrolytes also have limited electrochemical stability, which means that they lose their ability to produce an electrical charge over time. In addition to MIT, scientists from the Samsung Advanced Institute of Technology, the University of California at San Diego and the University of Maryland also conducted research on the project.

The findings were published in the peer-reviewed journal Nature Materials and the researchers described the solid-state electrolytes as an improvement over the current lithium-ion batteries we are using today. Electrolytes are one of three main components in a battery along with anode and cathode terminals.

The electrolyte component of the battery separates the battery's positive cathode and negative anode terminals while allowing the flow of ions between terminals. A chemical reaction then takes place between the two terminals, producing an electric current.

Previous problems with solid electrolytes are that they were incapable of conducting ions fast enough to be efficient energy, producers. The team of researchers from MIT and Samsung say that they have overcome that problem. Another advantage of a solid-state lithium-ion battery is that it can perform under very cold temperatures with Ceder calling this breakthrough "a real game-changer" that creates an "almost perfect battery".
