What is a computer Application?
-It is a type of software that allows you to perform specific
tasks.
◦ Desktop Applications
◦ Mobile Applications
You may have heard people talking about using a program, an application, or an app. But what exactly
does that mean? Simply put, an app is a type of software that allows you to perform specific tasks.
Applications for desktop or laptop computers are sometimes called desktop applications, while those for
mobile devices are called mobile apps.
When you open an application, it runs inside the operating system until you close it. Most of the time, you
will have more than one application open at the same time, which is known as multi-tasking.

App is a common term for an application, especially for simple applications that can be
downloaded inexpensively or even for free. Many apps are also available for mobile devices and even
some TVs.

4. Desktop Applications:
WEB/INTERNET BROWSERS
◦ A web browser is the tool you use to access the Internet
Web browsers: A web browser is the tool you use to access the Internet. Most computers come with a web
browser pre-installed, but you can also download a different one if you prefer. Examples of browsers
include Internet Explorer, Mozilla Firefox, Google Chrome, and Safari.
Slide 6
Desktop Applications:
GRAPHIC DESIGN SOFTWARE
◦ This refers to apps and programs that graphic designers use to create, edit,
and manipulate digital images. They allow designers edit and resize
images, produce original illustrations, combine text, color, and shapes,
and bring their vision to life.

Desktop Applications:
REAL-TIME COMMUNICATIONS (RTC)
◦ This is any mode of
telecommunications in which all
users can exchange information
instantly or with negligible
latency or transmission delays. In
this context, the term real-time is
synonymous with live. In RTC,
there is always a direct path
between the source and the
destination.

6. What Does Mobile Application Mean?
A mobile application, most commonly referred to as an app, is a type of application software designed to run on
a mobile device, such as a smartphone or tablet computer. Mobile applications frequently serve to provide users
with similar services to those accessed on PCs. Apps are generally small, individual software units with limited
function. This use of app software was originally popularized by Apple Inc. and its App Store, which offers
thousands of applications for the iPhone, iPad and iPod Touch.
Mobile applications are a move away from the integrated software systems generally found on PCs. Instead,
each app provides limited and isolated functionality such as a game, calculator or mobile web browsing.
Although applications may have avoided multitasking because of the limited hardware resources of the early
mobile devices, their specificity is now part of their desirability because they allow consumers to hand-pick
what their devices are able to do.
The simplest mobile apps take PC-based applications and port them to a mobile device. As mobile apps become
more robust, this technique is somewhat lacking. A more sophisticated approach involves developing
specifically for the mobile environment, taking advantage of both its limitations and advantages. For example,
apps that use location-based features are inherently built from the ground up with an eye to mobile given that
the user is not tied to a location, as on PC.
•Gaming apps: The equivalent of computer video games, they are among the most popular types of apps. They
account for one-third of all app downloads and three-fourths of all consumer spending.
•Productivity apps: These focus on improving business efficiency by easing various tasks such as sending
emails, tracking work progress, booking hotels, and much more.
•Lifestyle and entertainment apps: Increasingly popular, these encompass many aspects of personal lifestyle
and socialization such as dating, communicating on social media, as well as sharing (and watching) videos.
Some of the most widely known apps such as Netflix, Facebook or TikTok fall into this category.
Application vs. Apps
Applications are software programs developed for end-users to accomplish specific computing tasks. Apps, on
the other hand, mostly refer to programs developed for mobile devices. Both depend on the platform and
operating system they were designed for.

What is a computer Device/Driver?
A computer driver is a set of files that help your computer’s operating system interface with
certain pieces of hardware, like a graphics card.
Computer driver definition
A computer driver is a set of files that help your computer’s operating system interface with certain pieces of
hardware, like a graphics card. Think of it as a team of translators passing instructions between a factory’s
management and its machinery operators. As long as the drivers are doing a good job, things are likely to run
smoothly. But like a scene from a bad sitcom, mistakes from the translators can lead to chaos on both ends.

What do computer drivers do?
Computer drivers help your operating system use hardware correctly.
Each piece of hardware has its own drivers, and usually, drivers are written by the hardware
manufacturers.
Some hardware may not work at all without a driver, while others may only offer basic functions.

advanced functionality, you may need to install the drivers.

Why do computer drivers cause
crashes?
➢Buggy coding
➢Faulty installation
➢The drivers are outdated
➢Conflicts with other drivers
➢Conflicts with hardware
Computers crash for many reasons. Your machine may suffer performance issues due to a faulty component,
an inadequate power supply, or defective hardware, or it may crash because of a malware infection (you can
check by using a free antivirus scan). But you may also see the Blue Screen of Death (BSoD) due to
malfunctioning computer drivers. In fact, most crashes occur because of bad drivers (double entendre not
intended).
Here are a few reasons why computer drivers may be crashing your computer:
•Buggy coding- If you have a website or an online application, one of the things that you will run into is buggy
code. It's a fancy term for coding that either works in a specific way or doesn't work at all. When you have this
type of issue, you will have to fix it.
•Faulty installation-
•The drivers are outdated
•Conflicts with other drivers
•Conflicts with hardware
