Computer Questions

What is important to look at when buying a computer? Which model would you recommend?

When you buy a computer you look if have the characteristics necessary for your workplace ,if have enough hardware characteristics for what you wanna do or for how much cost. I can recommend desktop because you can upgrade all the hardware when start be slowly and is faster to play games or something, but if you wanna take a computer you need to take one for what you wanna do, if you normally don't stay in your house and you need a computer in your work you buy a laptop, but if you only need the computer for your home it's better buy desktop.

How can I change my computer into a newer and faster version? Is this a good option or should I buy a new computer?
You normally can buy all the pieces individually and change for your necessity, some pieces are compatible with other pieces but you can search and buy specific models. I normally upgrade my computer before buy a new because is cheaper but in some cases you need to buy a new computer because your hardware is old and you can't find compatible pieces.

How many types of monitors are there in the market? What are the differences? Which would I advise to buy?

LCD and CRT.

LC stands with liquid crystal display and is newer and a flatter type of computer screen.

CRT stands with cathode ray tube, is the traditional glass-screen television used like monitor.

It is better to buy LCD monitors because they don't have a big difference of price compared with CRT and are the best option to buy. CRT monitors are hard to find because people don't wanna buy.

What is secondary memory? What are the devices used for this kind of memory? Which are the best ones in the market?

A secondary memory is a type of mass and permanent storage, with high size to store but less speed compared with RAM.

Floppy disc drive (FDD), Hard Disc Drive (HDD), Tape drive, Reader or Burner Optical Disc (OD), Flash card and Solid-state drive (SSD).

For me SSD are the best in the market because they are faster than other and let you use less RAM when you use a program but are expensive and have less storage.
