Desktop computer VS Laptop computer

When deciding between purchasing a desktop computer or a laptop computer, you'll need to consider a handful of criteria and make a determination that fits your needs the best. Below is a chart that compares the two types of computers, providing pros and cons for each to help you make a more informed purchasing decision.

Topic	Desktop	Laptop
Cost	There is a wide variety of component options available for desktops, allowing for a large range of prices, but the starting point is relatively cheap. Desktops can start as low as $400 for a full package (computer & monitor) and still be a pretty powerful system.	Laptops can have a fairly wide variety of component options, but they are more limited than desktops. To get a more powerful laptop (higher speed, better graphics, more storage space, etc.), the price can be considerably higher, ranging up to $1500 or more, depending on the brand.
Portability	Desktops are large in size and have a separate monitor. While it's possible to take a desktop from place to place, it's cumbersome and not the choice for portability. They are designed to be used in a single location and not moved around much, if at all.	Laptops are very portable due to their compact size. They were designed to be taken from place to place, carried in a backpack or laptop carrying case. They are great for on-the-go use.
Processor	Desktop processors are a little bit larger in size, but this also means the desktop processors can be more powerful than laptop processors. New, advanced processors on the market are typically available in desktop computers first.	Laptop processors have nearly caught up to desktop processors, but are still limited when compared to desktop processors. Gaming laptops can have an equal performance, but have a much higher price.
Ease of assembly	Setting up a desktop takes a bit of extra work to hook everything up, start it up, and begin to use. It also requires more space to set up. While it's not difficult to connect everything together, it is still more cumbersome than a laptop.	Laptops are built to be easy to use, requiring little time to get running. Take it out of the box, plug it in and press the power button. Within minutes, the laptop is ready to use.
Keyboard	Desktops can make use of full size keyboards, including a number pad. There are really no limitations.	Smaller laptops with the 14" and 15" screens typically have smaller keyboards and don't feature a number pad on the right side. Larger laptops with 17" screens do have larger keyboards and may include a number pad, but the laptops are bulkier and heavier.
Screen size	Desktop monitors can be 19" or larger. It is even possible to hook up a desktop to a TV, so screen sizes could be as large as a TV. This provides for great flexibility on what the desktop is used for and in what environment.	Since portability is a big feature of laptops, smaller screen sizes are necessary and screen sizes typically range from 10" to 17". However, a laptop can still be connected to an external display and support any size of monitor, screen, or projector.
Power Usage	Desktop computers typically use more power than a laptop. They have to power a higher wattage power supply, multiple components inside the computer, and a monitor. If the power fluctuates or goes out, including brown outs, any documents being worked on and not saved can be lost.	Laptop computers use less power than a desktop computer. Smaller components means less power is needed to make them work. Laptops also have a battery, so power fluctuations and outages will not cost any unsaved work to be lost. The battery kicks in immediately when power fluctuates or goes out.
Upgrading	Most components in a desktop are easily removable, making it easier to upgrade and since desktop cases are usually much bigger they're easier to work in when doing any upgrading.	Memory and hard drive are about the only components that can be upgraded in a laptop. The remaining components are either built-in and not removable or the laptop is not designed to work with an upgraded version of a component. A need to upgrade anything other than the hard drive and memory usually requires a new laptop.
Gaming	Desktops are capable of using high-powered video cards that have higher power requirements and require better heat reduction/dissipation. Due to the space in a desktop and the capability of using 1000+ Watt power supplies, virtually any video card could be used in a desktop, including two or more video cards at the same time.	Physical space is limited in a laptop, which can limit the graphics capabilities. While higher-end laptops can provide better than average graphics for gaming and CAD-based applications, the heat reduction/dissipation is limited by the space in the laptop case. Power is also limited which doesn't allow for video cards needing those higher amounts of wattage to run.
Repair	Repairing a desktop computer is much easier since most of the hardware can be easily purchased off the shelf of any local computer retail store.	For most users opening a laptop to repair a part can be difficult and finding a replacement part often requires calling the computer manufacturer or ordering from another online site.

The main difference between 3G and 4G is speed – 4G brings broadband to your phone. If you want to future-proof your mobile communications and entertainment, you need 4G, with speeds of up to ten times faster than 3G.

The ‘G’ in 3G and 4G stands for ‘generation’. With 4GEE, EE has the latest and fastest phone network in the country, enabling you to watch live TV, stream a film or try multiplayer gaming on your phone.

Our 4GEE network is the biggest in the UK and it’s still growing. Why not check your coverage now?

And there’s also double speed 4GEE, already available in 20 towns and cities.

Rent the latest films from our Film Store and watch them on your phone, tablet or laptop. With double speed 4GEE, a film from the EE Film Store can now take just three minutes to download instead of 20 minutes on 3G.

With Deezer, our mobile music add-on for your phone or tablet, you get access to a catalogue of over 30 million tracks. 10 million people already use Deezer every month, so, whatever you're into, you'll find what you want on Deezer. With 4GEE and Deezer, downloads are far quicker and streaming is so much smoother than before.

JPG vs PNG

There is no one-size-fits-all for image file formats. With multiple options to save or export your images, the decision can seem complicated. Fear not! This post will cover two of the most popular file format options, JPG vs. PNG, including when to use them and why.

Qualifying questions

There are two main questions to ask yourself when you decide which image file format to use.

First, what type of image is it? Is it a casual picture of your dog, or a detailed graphicwith a professional purpose? Will it need to be altered or resized from it’s current state?

Second, how do you plan to use this image? Will it be published on a company website? Or, will it be for your own personal use?

The answers to these questions will help guide you to select your optimal file type.

What is a JPG?

The JPG image file type, typically pronounced jay-peg, was developed by the Joint Photographic Experts Group (JPEG) in 1992. The group realized a need to make large photographic files smaller, so that they could be more easily shared.

Some quality is compromised when an image is converted to a JPG. The reason is because the compression is lossy, which means that certain unnecessary information is permanently deleted. A JPG does, however, allow you to create smaller file size than you could with a PNG.

A JPG should be used in any situation when it’s important to have a small file. Beyond the initial saving as a JPG, there are tools that will allow you to shrink the file further. This is useful for web images, as the smaller size will increase the speed at which the page loads.  As broadband internet connections become more universal, this is becoming less of an issue. However, those with slower internet connections or older, less powerful computers will thank you for your consideration.

What is a PNG?

The PNG file format, usually read aloud as ping, was created in the mid-1990’s to act as a replacement for the Graphics Interchange Format (GIF). Limitations of the GIF prompted the creation and prevalence of the PNG.

An important benefit, and oftentimes deciding factor for using a PNG file, is that–unlike a JPG–they support transparency. This allows you to have a transparent background around an irregular-shaped object and avoid a white (or other colored) box outlining your image. If you require transparency, you’ll definitely want to opt for a PNG.

File compression for a PNG is lossless. Like the term indicates, lossless compression retains all of the data contained in the file, within the file, during the process. Lossless compression is necessary when you have images that are still in the editing process. PNGs are often used if size is not an issue and the image is complex, because a PNG file holds more information than a JPG. 

What Is a Keyboard Shortcut?

In computing, a keyboard shortcut is a set of one or more keys that invoke a command in software or an operating system.

They are typically an alternate means for invoking commands that would otherwise be accessible only through a menu, a mouse, or an aspect of the user interface. These shortcuts can expedite common operations by reducing input sequences to a few keystrokes.

These shortcuts can provide an easier and quicker method of using computer programs. These commands are commonly accessed by using the Alt ket (on PC computers), command key (on Apple computers), Ctrl, and Shift in conjunction with a single letter.

These shortcuts are for the following programs and applications.

• Word

How to Create a Windows Shortcut Key

1. Open the folder or directory that contains the program you wish to create a shortcut for.
2. Right-click on the program and click Create Shortcut.
3. This will create a shortcut named "Shortcut to <your program>" in the directory you are in. If you wish to rename this shortcut, right-click the file and click Rename.
4. Once the above steps have been completed, you can copy this shortcut and paste it anywhere to execute this program.

Once the shortcut has been created, you can assign a keystroke to that Windows shortcut.

1. Right-click the shortcut and click Properties.
2. Click the Shortcut tab.
3. Click in the Shortcut key box and press a letter. For example, if you press "p", the shortcut key will automatically be made to Ctrl + Alt + P. Which means that if saved, pressing Ctrl and Alt and P will run that shortcut.
