What is Computer CPU, Disk and Memory?

Computer Desktop Running Windows OS


If you are Windows user, then open task manager, you will see many processes running on your computer, each of the process has its own CPU, disk and memory usages. Sometimes it's using a lot of memory, sometimes it is using Disk or CPU. So what's that CPU, disk and Memory mean to us? Here's some little information i can provide.

1. CPU

It's stands for central processor unit (CPU), in computer is like the brain of computer, it so important component of a computer, to do it's computing job. It handles basic instructions and allocates the more complicated tasks to other specific chips to get them to do what they do best. It’s the core of your PC, smartphone, or tablet. and it’s what makes the whole device run as it should.

The famous CPU you often heard is the AMD CPU and Intel CPU. Intel is more popular by their Intel Core I series, like Core I7 and the latest Intel Core I9.

2. Disk

Disk storage is a general category of storage mechanisms where data is recorded by various electronic, magnetic, optical, or mechanical changes to a surface layer of one or more rotating disks. A disk drive is a device implementing such a storage mechanism.

In today's computer, there's two major types of computer disk, the HDD (hard disk drive or traditional hard disk) and SSD (solid state drive). HDD is cheaper meanwhile SSD can be twice as expensive, but the performance is correlated with the price.

3. Memory

Memory in computing refers to a device that is used to store information for immediate use in a computer or related computer hardware device. Memory is often called RAM (random access memory) is typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.

Type of memory or RAM is categorized by it's amount of storing capacity, it can be 4 GB RAM, 8 GB RAM, 16 GB, 32 GB, 64 GB and so on.

The three of that component is sometimes the most vital component for computer to be running in high speed or not. The three factor of computer, the higher number version of CPU, disk and memory is correspondence with the computing calculations speed. You can upgrade.

The easiest way to make your computer from slow performances to be slightly faster is to reduce the number of program you don't need. Even though you don't open it, sometimes it has program service that can run automatically whenever you start your computer. Uninstall the heavy computer program you don't need. In windows, to uninstall simply go to control panel, right click on the program, and hit uninstall.

To prevent program from running automatically when you start your computer, in Windows OS, go to Task Manager, then the Startup tab, right click on each program and click Disable. It has no downside effect even you disabled all items on the Start up.

Sometimes a computer program can use so many of your computer memory, sometimes the CPU, sometimes the Disk. That's depends on the developer of that software, whether they are optimizing those program to be user friendly or they just don't care or don't know about the computer resources management.

Google Chrome, the famous browser developed by Google is one of the example computer program that is usually use a lot of our computer memory and disk, it is because Google Chrome has so many process need to do in order to run the browser smoothly. That underlying process is essential for Google Chrome to be running and behave to make the best user experience possible.

MySQL and MariaDB password As already mentioned in the title of this blog, this error message sometimes occurred when we are trying to update our root password database, either MySQL or MariaDB, The error says: ERROR 1348 (HY000): Column 'Password' is not updatable This is because if we use this SQL command to update our database root password, and it turn out to be Restricted by MySQL to use update on mysql database. UPDATE mysql.user SET Password=PASSWORD('1234') WHERE User='root'; The solutions for MySQL Error1348 So you can not update a user password using Update commands, to update the password, use ALTER commands instead. like the following. ALTER USER 'root'@'localhost' IDENTIFIED BY '1234'; And then you need to do the flush privileges to commit previous queries (that alter command above) into the system, simply do like this. flush privileges; So now you have your root with password 1234. Although it is recommended to...

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po...

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl...
