How to Check Computer Specifications

Three Methods: Windows, Mac OS X & Linux

 Software အသစ္တစ္ခုကို Computer မွာ Install လုပ္ေတာ့မယ္ဆိုရင္ မိမိကြန္ပ်ဴတာႏွင့္ ကိုက္ညီမႈ ရွိမရွိ အရင္ဆံုး စစ္ေဆးရပါမည္။ ထို႔ေၾကာင့္ မိမိကြန္ပ်ဴတာ Model အဆင့္ကိုၾကည့္တက္ရပါမည္။

Method 1 of 3: Windows 

1)      Open the System window. This can be accessed by pressing the Windows key + Pause, or by right-clicking on Computer/My Computer and selecting Properties. In Windows XP, this is called System Properties. 

2)      Find your system specs. They are located in the “System” section of the Properties window, or the “Computer” section in Windows XP. You will see the following information:

• Processor - This is the speed of your CPU. Virtually all processors will be Intel or AMD. If you are unsure what the processor model means, do a web search to see the details.
• Memory (RAM) – This is the amount of memory you have on your computer. If you have a 32-bit operating system, you can only have up to 4 GB of RAM, even if you have more installed.
• System type – This will tell you what version of Windows you are running. Newer versions of Windows will also tell you if you have a 32-bit (x86) or 64-bit (x64) processor.

3)      Check your installed graphics card. Click the Device Manager link in the System window. Expand the “Display adapters” section of the list. Your installed graphics adapters will be shown. 

4)      Check your free hard disk space. Open Computer/My Computer/This PC. Newer versions of Windows will show a bar of the amount of free space available, as well as list the numbers. If you are using Windows XP, right-click on the drive and select Properties. The free space will be represented by a pie chart.

Method 2 of 3: Mac OS X 

1)      Click the Apple menu. Select “About This Mac”. 

2)      Click “More Info”. This will open a new window that lists your Mac system specs. You will be able to see the following system information:

• Processor - This is the speed of your CPU. Virtually all processors will be Intel. If you are unsure what the processor model means, do a web search to see the details.
• Memory (RAM) – This will show the amount of system memory you have installed. The more memory you have, the greater your capability to run multiple programs at once or memory-hungry programs like Photoshop.
• Graphics Card – This will display your installed video adapter, if any. You can do a web search on the make and model for more details on what kind of capabilities your adapter has.
• Software version – This is the version of OS X you are running. Both the name (Lion) and the version number (10.7) will be displayed.

3) Check your free hard disk space. Click the Storage tab at the top of the About This Mac window. Your hard drives will be listed, along with the space that you are using and the amount of space you have remaining.^[1]

Method 3 of 3: Linux 

1)      Open your distribution’s graphical system monitor. Most modern Linux distributions have a graphical interface that can display your system specifications much like Windows. For example, the program is called System Monitor in Ubuntu. Programs such as these will display:^[2]

• Operating system – Your operating system (Ubuntu) and version number will be shown at the top.
• Memory – This is the amount of RAM you have installed on your system. More RAM means your ability to run multiple programs is increased.
• Processor – This is the CPU you have installed. If there are multiple identical processors listed, each one represents one of the cores on your processor. Do a web search for your processor model to see detailed specs.
• Available space – This is the amount of free space you have on your hard drive.

2)      Download a more detailed program. You can get programs that give you much more details about all of your installed hardware. These are typically available from your distribution’s repository. For example, on Ubuntu you can install a program called HardInfo.

3)      Use the terminal. As with virtually everything on Linux, you can check the specs of your computer from the terminal. There are several ways you can go about this, and they are similar for virtually all Linux distributions.

• The folder/proc/ contains information about your system setup. Each aspect of the system has a separate file. Use the cat command to read the files you need. The most useful ones include:
• cat /proc/cpuinfo - This will show you information about your installed processor.
• cat /proc/meminfo - This will show information on your installed RAM.
• cat /proc/partitions - This will show information on your hard disk partitions.
• Use lshw to display your system specs. You may need to install it before you can use it. To install lshw, use the following command: sudo apt-get install lshw. Run lshw by typing sudo lshw to display a full list of your hardware, or sudo lshw -short for a brief list.[3]

How to Print to a Shared Mac OS X Printer from Windows 7 & Windows 8

There are a number of indirect ways that you can trick Windows 7 and Windows 8 into printing from a shared printer attached to a Mac, but the best way to do it is through Bonjour. That’s because with every version change - either between Windows or OS X - the process gets muddled and a new solution has to be devised. But Bonjour has been fairly reliable even as both operating systems have evolved. In this tutorial, you’ll learn how to set up OS X so that its shared printers are available to Windows computers and devices.
NOTE: This guide has been updated for Mac OS X Mountain Lion (version 10.8).

How to Enable Print Sharing in Mac OS X

In Mac OS X, first open System Preferences. In the Internet & Wireless section, look for the Sharing button. Click on it.

The Sharing window opens. Enable the checkbox near Printer Sharing. OS X then lists the printers installed on your Mac.

You can go ahead and share them from here. Check the box near the printer you want to share. Then, in the Users section, configure the sharing permissions. Select the users you allow to print and the permissions level assigned.
When done, close the Sharing window, and the System Preferences window.

How to Share a Printer Connected to a Mac OS X

Even though enabling printer sharing provides the options required to share a printer, there’s another way to share printers. First, printer sharing needs to be turned on.
Open System Preferences. In the Hardware section, look for the Print & Scan button and click on it.

The Print & Scan window opens. Here, you see the printers installed on your Mac. Select the printer you want to share. Then, check the box that says "Share this printer on the network".

If you want to customize how the printer is shared, click the Sharing Preferences button.

How to Add a Mac OS X Shared Printer to Windows 7 or Windows 8

Download Bonjour Print Services for Windows from the Apple Support website. As of this writing, the current version is Bonjour 2.0.2, which supports Windows XP Service Pack 2 or later. It also works in Windows 8. Installation is straightforward: run the setup file, agree to the terms (read them, if you’d like) and keep clicking Next until it’s finished.
Now, run the "Bonjour Printer Wizard". Make sure your Mac is up and running, connected to the network and the printer is connected and turned on. If all is well, Bonjour will automatically detect the shared printers. They’ll be listed as "PRINTER NAME @ COMPUTER NAME". Choose the printer you’d like to install and click Next.

If prompted, install the printer drivers. If you have the printer drivers installed on your computer already, you can choose them from the list. If not, you’ll have to locate them manually by clicking Have Disk. Make sure that you install the proper drivers for your specific printer model, otherwise you may have limited or no printer function.

After choosing the drivers, you’ll have an opportunity to verify the settings before finishing the printer setup. Click Finish if all looks good.

Now, the OS X shared printer will be available in the Devices and Printers panel of Windows. You can print to your Mac OS X shared printer as you would on a local printer, from the Print dialogue of the program you are using.
