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.

Spring Kafka - how to use ReplyingKafkaTemplate send and reply synchronously

By -

Microservice Spring with Apache Kafka Kafka is an asynchronous messaging queuing system, but when you have a case in your project that you need to have the result immediately from another service you can do that quite easily. Kafka from the client side produces a message to the server side, then waiting for the server to return back the message exactly what the client wants. It’s identified in the kafka header request named KafkaHeaders.CORRELATION_ID and a topic where the server should send. If the server side produces the same correlation id to the same topic in the request, then the client side will catch that message as its reply. Although you can work with kafka from a different framework and language other than Java and Spring. Here’s in this example i just specifically giving the example of sending and replying kafka messages using Spring Boot. The Project Overview The client-project will send a string message to the server-project over kafka, then the server-project wil

Usually you will need a pair of SSH username and password to connect to a remote server. But there's also another way to connect to the server via SSH but without password, just using a dot pem (example.pem) file. Here's how we usually do on Windows 1. Let’s SSH login using pem to confirm if it’s throwing error or the pem is fine, if error then we need to move to step 2 to fix it: ssh adam@10.0.0.123  -i server-cert.pem And here's the usual error that will throw if your pem file is not ready for SSH login. You need to follow the next step to make your pem certificate ready to login to your server via SSH. 2. Open Windows Explorer, then right-click on the pem file, then select "Properties". Navigate to the "Security" tab, and click "Advanced" 3. Disable inheritance 4. Delete all permissions, so it doesn’t have any permission 5. Now add you as the only only owner. By click button Add and then Select a principal, then Advanced. 6. On the showing p

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

flutter button left text Developing a flutter UI is very difficult for a beginner or I think any other technology it’s very intimidating for a starter. I remember my first time trying to make a button in Flutter that had left aligned text in it. I spent a lot of time on how to make it but never made it. Once you are getting familiar with flutter widget or component blocks, you can apply whatever style you want for your app. In html you can just do something like <button style=”text-align:left”>Text</button> but in flutter it is a bit tricky. So here I provide an example on how you can align text inside a flutter button to the left. Flutter button with left align text import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, visualDe
