These have historically been used to support desktop publishing software but now also offer a comparable system for general office use. The CPU is responsible for processing opentape.org all information from programs run by your computer. The ‘clock speed’, or the speed at which the processor processes information, is measured in gigahertz .
- Downloading and installing the latest versions of your programs might not only protect your PC, but can keep it working quickly.
- We regularly review our course content, to make it relevant and current for the benefit of our students.
- Designed for use on touchscreen mobile devices such as smartphones and tablets, Android is a mobile operating system created entirely by Android Inc., which Google bought in 2005.
- The first version of Windows was introduced in November 1985 as a graphical operating system shell in response to an increasing interest in graphical user interfaces.
Short range wireless broadband technology, also known as Wi-Fi is the essential piece of technology required for people around the world to access the internet, wirelessly. From schools and offices to homes, coffee shops and even cars, Wi-Fi is at the heart of modern connectivity. Large interactive touchscreens, touch tables, and touch walls are essentially much larger versions of handheld tablets, and were made popular in 2008 when Microsoft unveiled its ‘Surface’ table top. These tablets typically have a directional pad (D-Pad) attached to make the gameplay experience run more smoothly by giving greater user control. Electrical or non-electrical – motherboard or mouse mat, though when the exam board refer to PC hardware, they are referring specifically to electrical hardware. The keyboard and mouse usually come as part of a bundle, but you may be able to select wireless devices that make desktops neater.
Computers and hardware
The only safe use of direct clock speed comparisons is within a single family. A 1.2 GHz Tualatin-core Pentium III, for example, is roughly 20% faster than a 1.0 GHz Tualatin-core Pentium III, but even there the relationship is not absolutely linear. And a 1.2 GHz Tualatin-core Pentium III is more than 20% faster than a 1.0 GHz Pentium III that uses the older Coppermine core. Also, even within a family, processors with similar names may differ substantially internally. This course is specially designed to bridge the gap between electronics/hardware engineering and computer science/software engineering.
The hard disk stores the data you create in your business, as well as the programs you use. A typical office computer will have at least 500GB of hard disk space. Most new laptops and performance computers come with solid state drives . These drives are silent because they have no moving parts and are five to eight times faster than the standard magnetic hard disk drives used in most desktop computers. Although SSD can offer significant performance advantages, the cost per GB of storage can be two or three times more expensive for the same storage capacity.

It also limits the number of programs malware might “hijack” to gain access to the system. Power surges can put harmful stress on your computer, and in some cases damage the power supply and other components. Did you know surge protectors can lose their protection after undergoing just one power surge? Even if they still appear “on,” they may not be providing the protection you need. So it’s a good idea to check them from time to time, especially after a notable power surge. To help detect hard drive issues before they lead to other problems, Microsoft Windows provides a Check Disk tool.
Choosing the Right PCs and Laptops
Students opting for either the work placement or study abroad module will be registered on a non-credit bearing module. Whilst the modules do not bear credits, they do require completion of marked activities reflecting on your placement/study abroad or work placement experience. Following successful completion of the activities, the module selected will appear on your final academic transcript.
Let’s take the PC for example – are you looking for a relatively cheap Intel Core i5 processing power or something to play games on? For gaming nowadays, almost everyone goes for the more cutting-edge Intel Core i7 processors. You can go for a 128GB if you’re budget-conscious, 500GB if you’re looking for the perfect balance or a 1TB SSD drive for the ultimate in storage technology.
