What I learned so far...

      A browser is a program you use to surf the internet and within the browser there is a search engine. The top five browsers are Internet Explorer, Google Chrome, Safari, Mozilla Firefox, and Opera. Opera has a low profile which means it is a small program and does not take up a lot of space. Ad-ons are mini apps for your browser. You can use two types of software: one that you pay for and one that you can download for free. Free software is part of a project called open source software. A bit is the smallest amount of information a computer processes and is equal to a zero or one. It is also equal to the state of electricity on or off as zero is off and one is on. A byte is equal to eight bits. An AC adapter is known as an alternating current which is coming out of the wall. An AC adapter current has the ability to kill you. DC means direct current and will not kill you, just shock you. A system board is the core of the computer. The CPU is also known as the chip and a cord works faster than wireless.
      Desktops have motherboards and laptops have system boards. Motherboards are bigger than system boards and use expansion cards. Some examples of expansion cards are USB, sound expansion card, video expansion car, NIC (network interface card), and modem (for dialup). If a system board goes bad, then you have to replace the whole thing. Another name for a processor is the chip or CPU which is the central processing unit. It is the brain of the computer and does all the work. The hard drive stores all the long term information and the RAM or random access memory does short term information.

Definitions:

• Hard drive:
- An inflexible magnetic disk with greater storage capacity than a CD; can be internal to the computer or external
- A device used for storing large amounts of data for a computer that persist while the computer is turned off.

• RAM:
- Random access memory, This is a type of computer memory that allows data to be stored and retrieved as required. It is called random access because any part of the memory can be located without having to go through everything that comes before it.

• Processor:
- The Central Processing Unit (CPU) or the processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions.

• System board:
- A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals.

• Sound card:
- Is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs.

• Video card:
- A piece of hardware installed into a personal computer to allow it to send video signals to an external output device such as a monitor or projector

• Power supply:
- is a device that supplies electrical energy to one or more electric loads. The term is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy.
