Computer security, in basic terms means keeping your computer and the data that is in it safe and secure. More of our personal data is stored in or accessed from our computer, now more than ever before. Yet most people lack even the basic understanding of how to keep their computers safe and secure. By following just a few simple rules you can dramatically improve the overall security of your computer.Your computer has many windows and doors, not all of which are locked. New flaws are being found everyday, often with the fix not coming until days after. Just like you would not leave your front door unlocked, you should not leave your computer wide open either. The first two things we will discuss to help with this task are installation of a quality firewall and regularly updating There are two basic types of firewalls and both perform the same functions. One is hardware the other is software. A hardware firewall is probably included in your router if you are using one, while you may or may not have software firewall installed. To continue our house analogy, a firewall is like building a wall and gate around your home and giving the guard at the gate instructions on who to let in and out. While this does give a great deal of protection, it is not all that is required. Someone may know a way around or under your wall, or even be able to coerce the guard into letting them in. your installed software.A large percentage of infections are caused by the computer user themselves.
Over time a computer may be slow down due to various factors and reasons. Few of the important such as low memory, faulty hardware, system related errors, any computer virus and other infections and even many more factors can affect the computer and its functionality. If you eliminate all the factors that are causing the slow computer the system will be optimized automatically.
People are often frustrated when they have to call a help desk technician to get assistance with computer problems This is due partially to the fact that having computer problems is a frustrating experience so that sets the tone for a none-too-pleasant set of circumstances
A PC can be a powerful and great tool. It provides you a variety of Benefits, as well as the Ability to quickly turn out High-quality work. It also permits you to be taught New skills that are an
Important part of today's World.
A computer is an electronic device that manipulates information, or "data." It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the Internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.
All general-purpose computers need these hardware components:
Motherboard with a CPU.
The CPU is under the fan on the motherboard. The motherboard is the main circuit board in the computer. The Central Processing Unit (CPU), is used to communicate with other components.Traces carry signals and voltages across the motherboard. The motherboard has multiple layers carrying data for the Processor, Memory bus, and BIOS. An important component of a motherboard is the microprocessor's chip-set, which provides the supporting interfaces between the CPU and the various buses and external components. Motherboards include logic and connectors to support commonly used input devices, and include logic and connectors to support commonly used input devices.
Memory: allows a PC to store, a minimum of, information and programs.
Mass storage device: permits a PC to permanently retain giant amounts of knowledge. Common mass storage devices are disk drives.
Input devices: a keyboard and mouse, the input device is the conduit through which information and directions enter a PC.
Output device: a visual display unit, printer, or alternative device that permits you to see what the PC has accomplished.
Central processing unit (CPU): the center of the PC, this is the part that truly executes directions.
In addition to those elements, each PC needs a bus that transmits information from one part of the pc to a different.
All of these devices work together to make it happen.

I started in computers with an Electronics degree back in 1983 when Electronics meant troubleshooting to the component level. An average computer at that time cost around
$10,000. Understanding circuits and troubleshooting was the key to success. Now changing Boards are all thats needed to know. After school I went to work for a Start-Up Company as Production Manager and designed 7 surge protectors that the company patented. I also hold 33 Certifications in HP and OKI printer repair. In 2002 I went back to school for an a Associate of Computer & Networking Degree.
