our computer allows you to do some really amazing things. Digital photo editing, sophisticated computer gaming, video streaming—all of these things are possible because of different types of software. Developers are always creating new software applications, which allow you to do even more with your computer.
Installing from a CD-ROM
From the mid-1990s through the late 2000s, the most common way to get new software was to purchase a CD-ROM. You could then insert the disc, and the computer would walk you through through the installation.
Now, almost all software has moved away from this model. Many new computers no longer include a CD-ROM for this reason. However, if you do need to install software from a CD-ROM, simply insert the disc into your computer, then follow the instructions.
Installing software from the Web
Today, the most common way to get new software is to download it from the Internet. Applications like Microsoft Office and Adobe Photoshop can now be purchased and downloaded right to your computer. You can also install free software this way. For example, if you wanted to install the Google Chrome web browser, you can visit this page and click the Download button.
The installation file will be saved to your computer in .exe format. Pronounced dot e-x-e, this is the standard extension for installation files on Windows computers. You can follow the steps below to install an application from an .exe file.
Locate and download an .exe file
Locate and double-click the .exe file. (It will usually be in your Downloads folder.)
A dialog box will appear. Follow the instructions to install the software.
The software will be installed. You can now open the application from the Start menu (Windows 7) or the Start Screen (Windows 8).
What Is A Hardware Driver
In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.
A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

What Is A Computer Virus
A computer virus is malicious code that replicates by copying itself to another program, computer boot sector or document and changes how a computer works. The virus requires someone to knowingly or unknowingly spread the infection without the knowledge or permission of a user or system administrator. In contrast, a computer worm is stand-alone programming that does not need to copy itself to a host program or require human interaction to spread. Viruses and worms may also be referred to as malware.
A virus can be spread by opening an email attachment, clicking on an executable file, visiting an infected website or viewing an infected website advertisement. It can also be spread through infected removable storage devices, such USB drives. Once a virus has infected the host, it can infect other system software or resources, modify or disable core functions or applications, as well as copy, delete or encrypt data. Some viruses begin replicating as soon as they infect the host, while other viruses will lie dormant until a specific trigger causes malicious code to be executed by the device or system.
Many viruses also include evasion or obfuscation capabilities that are designed to bypass modern antivirus and antimalware software and other security defenses. The rise of polymorphic malware development, which can dynamically change its code as it spreads, has also made viruses more difficult to detect and identify.

What Is Touch Typing?
Touch typing is the ability to use muscle memory to find keys fast, without using the sense of sight, and with all the available fingers, just like piano players do. It significantly improves typing speed and eliminates errors. Touch typing simply makes you more productive and it is a skill worth learning. However, many people engage in the bad habit of ‘hunt-and-peck’ typing, even those seasoned professionals with years and decades of computer experience. It is easy to understand, though, as touch typing requires dedicated practice to learn it well.
