Buzz Byte – basics.

Desktop, Laptop, or Tablet – the choice is yours!

This month, rather than advice, I thought we’d look at some of the abbreviations used in the industry and what they stand for.

The three main computers that are sold today are the desktop (the large tower unit), a laptop (flip-open device with screen and keyboard) or a tablet (often touch screen, but can come with additional keyboard). Once you have decided which device best suits your needs you need to look into the specifications to ensure it will meet your requirements.

The OS is the Operating System – usually either Windows or Mac (Apple). The majority of PCs stocked will come with Windows 10.

Now for the guts of the PC! HDD stands for Hard Disk Drive which stores the computer programmes and all your data. (That goes down and you’re in trouble). It is recommended to take regular backups as the data isn’t always retrievable. I know, I lost over 2k thousand words of a book I’m writing, but now I use Googledrive to keep a backup. Pop into any good computer store if your are worried to discuss how you can safeguard against loss of data – but remember, no protection is 100%!

The CPU, which is the Central Processing Unit, runs the programmes stored on the HDD. Each CPU will have a set GH (Gigahertz) which denotes the speed of processor; the higher, the faster. One last important factor to running a PC is the size of the memory; the lower the memory the slower the PC will run. Memory is referred to as Ram – Random access memory. When looking at specifications of PCs you will also come across some standard features such as Bluetooth (BT), HDMI which is a connection for an external monitor or TV and USB (Universal Serial Bus) which is the socket to plug in external devices ; you may need to consider how many external devices you need to run at any one time (most computer stores have hubs which increase the number of USB ports.)

Storage can be a tricky one to work out, as the sizes jump from a MB (Megabyte) to GB (Gigabyte) to TB (Terabyte), but basically the bigger the size the more you can store ; it does depend on the quality and initial size of the picture / file. For example Sandisk suggest that you can store over 45k images that are 4 megapixels or below on 64GB memory card.
