Degree: MEng Computer Science G401 (Masters) - Southampton University
Im reading Computer Science at the University of Southampton, and am an all round computer enthusiast. I love to talk anything computers and am happy to help with any mathematics or computing based work you might have.
What I can help you with:
I can also help with a wide range of A-level or GCSE level computing and GCSE mathematics work, having studied both subjects at A-level and having Maths as an integral part of my Computer Science course at university.
In our sessions you will very much guide what I teach. It helps if you let me know what exam board you are doing an exam for so I can find the specification for it online, but if you dont then all you need to do is let me know what you want to learn and I can help you with what you need to know.
Get in touch with me for a quick talk about what I can offer and what you want out of our sessions!

A HDD is a mechanical form of storage, using electromagnetism to store and write data.
Mechanical drives are very prone to data lose and breaking when moved around, due to their mechanical nature.
They consist of two main components, an actuator (Consisting of an "Arm" that does the reading and writing), and a platter on which the data is stored.
Data is arranged in concentric (Non spiral) tracks around the platter and are further divided up into segments which run from the center of the pllatter to the outside (Think slices of pizza).
When reading or writing, the arm moves out to the correct segment and then the platter spins so that the arm can get to the correct segment. At this point the arm can either receive the bits of data on the HDD or send out electric signals to re-write the bits on the disk.see more
