You're just confused when you're looking for computers. Many newcomers are frustrated and it seems that the vendor in the local big box store seems to speak a foreign language. Numerous terms and words apply to the computer industry, which does not apply to other living conditions. What is software? What is hardware? What about CPU? ROM? RAM? Let's look at some instant computer hardware.
Computer hardware is just that, the "hard" surfaces you can access. Hardware is a computer. Software is software running on hardware that tells the computer what to do when the computer is used to balance the checkbook, to view email or surf the web. Examples of computer hardware:
o Monitor – viewing results as a television.
o The CPU is a central processing unit where all the complicated maths and computing takes place.
o CD or DVD ROM – This is the drive that reads CDs or DVDs. ROMs are non-burning, "read-only".
o CD or DVD RW – These drives "burn" or "make" CDs and DVDs. Typically you can write and write to a CD or DVD.
o Memory – This is how you read it; the more memory your computer has, the better it will be.
o Printer – This allows you to print documents (autobiography, images), and printers often have more features. Many printers can duplicate such as scanners, fax machines, and copiers.
o Wireless or wired routers – these are devices that allow you to connect to a "network" for other computers. They can operate independently or through the "modems" that are devices that allow you to connect to the Internet.
Although the above list is quite extensive, it does not include all the examples of computer hardware that you can learn. Most devices are hardware. (Do not forget to touch the hardware.) The list of non-listed devices includes cds and dvds, flash drives, floppy disks and disks, the mouse and the keyboard, as well as hard drives for operating systems and software is stored.
Computers have different hardware configurations. Some people offer more memory, storage or optional drives. The type of computer you want to buy depends on what you are doing. There are many configurations available for practically every application and desire. Whether you're playing games, sending e-mails, surfing the web, or depicting the distance between planets and stars, there is a computer that is ready to buy. Each one is configured a bit differently, depending on the extent to which your applications are picking up the hardware.
Hopefully, you are now better able to understand the various examples of computer hardware and make informed choices when purchasing the next computer.
