Sorry to be vague but I am not sure what is relevant.
A middling budget is not a problem but I do not want to spend money on software/hardware that I will never use.
The last television I had was analogue and when that went digital, I watched programmes on this laptop with a plug in mini amp. This laptop is a 4GB DDR3 memory / 500 GB HDD and the screen is approx. 38 cm. I would like double that size and I would like good speakers. Should they be integral or separate? I have not had a problem with memory, however laptop is slow and fibre optics have not reached this part of the world. The laptop is old. When I get my new one I will keep it for years, so I want to get it right. I presume there are 3 hardware parts to the set up, a processor, a screen and a keyboard and maybe speakers if not integral. When I go to a shop to buy, I want to offer more than, "I want a computer, please." However, I am learning already, I understand I should have SSD and HDD. Thanks.
Integrated speakers typically are very, very bad. If you care about audio fidelity, you want to look for external speakers.
So if I understand you currently you're more looking for a general guide of what to be aware of. Right.
SSD (Solid State Drive) > HDD (Hard Disk Drive). SSD and HDDs are the components that hold the data your computer stores - that would mean videos, photos, text documents etc. are stored on this component.
SSD's are a ton faster than traditional hard drives - this means a overall much faster computer. They are however more expensive than hard drives per gigabyte. If you're up for paying the little extra, an SSD is absolutely worth it.
Memory (also called RAM) determines how good the computer is at multi-tasking. More memory results in better performance when using multiple tabs, documents, etc. The standard nowadays is around 8GB of RAM.
What you will need to buy: a computer (I believe you are confusing this with the processor. The computer is the actual box that contains the computers components. The two aforementioned components comes in this box), a screen, a keyboard, a mouse and potentially a set of speakers.
I hope that helps. Let me know if you encounter any further questions.
