Who decides the size of RAM?

Speed is the prime factor that anyone consider while purchasing a new computer system. Generally, speed of the computer depends on two factors, that is microprocessor used and main memory (RAM) available. Here, I will give focus on the RAM which directly affects the speed of the system. Many computer users think that you can attach any amount of RAM (main memory) to your computer system, But this is not true. I will explain this concept form engineer's point of view. As an example a 32-bit microprocessor with 32-bit address lines can access and use maximum of 4 GB of the RAM.

Let's see the basic computer architecture first.

Configure Wget for Proxy

As terminal is a strong component of Linux Operating System, we can use it for many ways and it is found that we can download files through terminal. Wget is the command from which we can download wweebpages, videos etc. But it is found that many us are bound to proxy. So it is possible to configure the proxy for the wget command.

1. First check whether you have installed wget or not, if not then install it using the command. 

Enable And Disable USB

In all operating system we are able to enable or disable hardware by configuring them. We can do same in Linux system from control center. In this blog we are going learn how to disable USB drive with the help of Linux file system. To do this we must know the file system used by Linux. Because  Linux uses file to configure every hardware connected to it. We get all driver files in /dev directory. The programming module of every driver is located at /sys/modules. From this module we are able to configure hardware changing in programming module. To disable the USB we have to look for USB module in same directory.
USB module is located at /sys/modules/usbcore, from this module we are able to configure the USB device. We can get all information of USB. This module contain all information regarding USB such as speed, buffer-size, version number, etc. There are lot of files that can be configured, but to do this we require root authority. We are able to read files from normal account but can not edit them. Now let's check our USB version number: Open file “/sys/module/usbcore/drivers/usb:usb/usb2/version”.

PHP: INCLUDE and REQUIRE command

Hi friends, I am Jakir Patel and today in the series of PHP tutorials we will learn how to include any file into some other file.

            Just like C,C++ and JAVA which includes many inbuilt header files in the program to enhance its usage and reduce the size of actual program code; Similarly, we can also include previous files into our current file to make repetitive code to be included easily.

INSTALL MULTIPLE SERVERS

Hello Linux lovers, today I am going to discuss about Servers Installation. Okay I am not going to show installation of every server that you need in your life, for example apache server,DNS server,PHP server etc. Instead of that I will show how to install all that servers in your workstation. Mainly we need server on Linux Server but it might be happens that you want to install those server on your Personal Computer for your commercial or Non-commercial usage.

When people start installation of server they don’t get any idea how to install that server. They started searching on Google and they find some commands to install it. But think is, when you want to install more servers that time finding commands to install each server is takes lots of time as well as you have to do more installations. Instead of doing this all kind of lengthy stuffs, we have a great command which make your installation so much easier than previous tasks.

TASKSEL is a command which helps you to install top 20 servers in your PC. TASKSEL is by default installed in Ubuntu Servers, but we can install it in your PC also by using command sudo apt-get install tasksel .

Fig:- Installing tasksel

After installing tasksel you can view it’s manual page also on terminal by typing man tasksel. When you use tasksel command in terminal it will show you all the top 20 server names. To install those servers use space button to select your server, then click on OK button and those servers that you have selected for installation they will start installing in your system. This is a easier way to install servers on your system, I hope it will help you.
