Do you think cookies come out of the oven? Pretty sure that the cloud belongs in the sky? Convinced that CSS is a type of boat? Never fear, Our Data & Technology Recruitment Consultant Ellie Martin talks us through the commonly misunderstood tech terms she has seen throughout her experience in the industry and in candidate's CVs!

As someone who previously worked as a software developer, and is now immersed in tech recruitment, I know my fair share of technical terms- however, what I’ve found is, a lot of people use them without really knowing what they mean! Below I’ve listed my top 10 misused and misunderstood tech terms…

6. What is a 'Cookie'?

Cookie is a term most avid internet users are familiar with, but are not sure what it actually means…

Simply put, cookies are text files with small pieces of data, such as your username and password, that are used to identify your computer. Specific cookies, known as HTTP cookies, are used to identify specific users and improve your browsing experience.

When you connect, data is created and stored in a cookie- which is then labelled with a unique; as the cookie is exchanged between your computer and the network server, the server reads the ID and can pull your specific information.


7. What are 'HTML' and 'CSS'?

Most of us have heard of HTML (HyperText Markup Language) and CSS (Cascading Style Sheet) but some may not know the exact difference between the two- essentially, HTML is used for the creation of webpages, and CSS is used to control the styling and layout.

HTML consists of elements and tags, which the browser can read to see the heading of the page, beginning and end of paragraphs, and so on.

CSS uses properties and classes that are mostly categorised broadly into presentation and layout- presentation defines text colour, font type, font size, background colour, images etc. and layout specifies the position of different elements.

A good way of thinking about it is HTML is the building blocks, and CSS is there to tell the blocks where to go and how to look (colour, shape, size etc.)

8. What is a 'Platform'?

Platform is a term that seems relatively self-explanatory, which is why it is so commonly misused… is it hardware, software, or both?

A computing platform, or digital platform, is the environment in which a piece of software is executed. It could be the hardware or operating system (OS), or even a web browser and associated application programming interfaces (or other underlying software)- as long as the program code is executed with it.


9. What are 'Memory' and 'Disk Space'?

I’ve heard my share of confusion around memory and disk space; in computing, memory refers to the temporary storage used by a computer; a computer loads programs and data into its memory to carry out tasks, this is known as RAM (Random Access Memory).

Disk space (or hard disk space) is a more permanent store, that holds files even after the computer is turned off; it’s from here that the computer loads programs and data into its memory.


10. What is 'Bandwidth'?

Last, but not least, we have bandwidth- we’ve all heard of it, and most of us have used it in conversation (probably incorrectly!), but what actually is it; bandwidth describes the maximum data transfer rate of a network or Internet connection- it measures how much data can be sent over a specific connection in a certain amount of time.

Bandwidth is used to describe network speeds, but it does not measure how fast bits of data move from one location to another, since data packets travel over fibre optic or electronic cables, the speed of each bit transferred is insignificant.

A good way to imagine this is thinking of a network connection as a tube, and each bit of data as a grain of sand- if you pour a large amount of sand through a thin tube, then it will take a longer time to flow through when compared to the same amount of sand flowing through a larger tube.
