Computer Repair Services by The Tulsa Geek

   I'm building a glossary, a list of basic and common terms that are specific to computers, computer hardware and software. 

   Understanding things is always easier when we know what the words mean.  Have you learned any


CPU:

This is the acronym for "Central Processing Unit".   This is an older term for processor and microprocessor, the central unit in a computer containing the logic circuitry in your computer: think of it as the Brains of your system.

DEFRAG:

Defrag is short for defragmentation.  In the course of using our computers the files (documents, letters, book chapters, etc.) that we create gradually "fragment", break into pieces like a dinner plate that has been dropped on the floor.  One difference is that it happens gradually, not suddenly as with the dinner plate; the other difference is that our computers keep track of the exact location of each of the pieces.  Defragging puts all the pieces back where they belong.

Each time we decide to change any of these documents it takes longer for it to load onto your screen because we have to wait for the computer to find all the pieces and put them together before they can popup onto our screens.  You can imagine how having many fragmented files slows down your computer.  The way to speed up your computer, therefore, is to do a process called defragmentation (defragging).  When you defrag your hard drive all of the pieces of all of the files are assembled into a single item.  This means that the files will now load much more quickly because they do not need to be reassembled.  Your Windows computer includes a defragmentation tool that will do this process for you.  There are also several tools that you can install on your system that can do your defragging in the background whenever you pause in your work for even a minute.  This will keep your system defragged just about all of the time.

MALWARE:

Malware, created from the words malicious and software.  Malware is software designed to infiltrate or damage a computer system without the owner's informed consent. It is a general term used by computer professionals to mean a variety of hostile, intrusive, or annoying software or program code. The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, including true viruses.

NETWORK:

Two or more computers or computer systems that are electronically connected within a home or business or the Internet itself.
Networks can be connected by wires or wireless devices or by "ethernet" cards and modems to the Internet.

SOFTWARE:

Software refers to programs that do specific tasks.  A program, is similar to a recipe for cooking a meal.  Programs use step-by-step logic to produce desired informational results.  They can be games or programs that calculate your income taxes.

TROJAN:

The Trojan horse, also known as trojan, in the context of computing and software, describes a class of computer threats (malware) that appears to perform a desirable function but in fact performs undisclosed malicious functions that allow unauthorized access to the host machine, giving them the ability to save their files on the user's computer or even watch the user's screen and control the computer.  Trojans can appear to you as free screen savers, games, etc.  They can appear to be anti-virus programs when, in fact, they are the exact opposite; destructive viruses.
