                                " THE MOTHERBOARD COMPONENTS"


AGP SLOT- the AGP expansion slot connects AGP video cards to motherboard. Video expansion cards are
                    also known as graphic expansion cards. AGP stands for Accelerated Graphic Port. AGP video
                    cards are capable of a higher data transfer rate than PCI video cards.
PCI SLOT-the Peripheral Component Interconnect slots is commonly known as the PCI slots, refers to a
                  computer bus. The computer bus is used by a computer to connect to a peripheral add-on
                  devices, such as network cards, sound cards, tv tuner, fire wire cards, graphics cards and many
                  other types of extensions cards.
ISA SLOT-An ISA slot is an early types of expansion slot used to connect peripheral cards to a computer's
                  motherboard . ISA stands for Industry Standard Architecture. The original ISA bus slot was 8-
                  bit to coincide with the 8-bit data width of the Intel 8088 processor.
CMOS BATTERY- CMOS BATTERY OR (the Motherboard battery) has a unique purpose in a computer.

           The 3 Basic Operation Of A PROCESSOR(CPU)

The CPU, or Central Processing Unit, is the part of the computer where work gets done. The heart of the computer is the central processing unit or CPU. This device contains all the circuitry that the computer needs  to manipulate data and execute instructions.
Therefore, the three Basic of CPU's are:
*control unit- is the components responsible directing the flow of instructions and data within the CPU, it is    
                     actually built of many other selections circuits such as decoder and multiplexors. The decoder
                     and the multiplexors compose the unit.
                   - a control unit in general is a central part of the machinery that controls its operations and
                     organized enough to contain any such unit.
                   -without the control unit, the computer could not follow directions and might not functions
                     properly because true of electronics devices that require timing or logical thinking when in
                    operation and also synchronizing information.
*buses-the information highway for the CPU. Buses are bundles of tiny wires that carry data between
            components. The three most important buses are the address, the data, and the control buses.
            -it is computing, is a set of physical connections which can be shared by multiple hardware
             components in order to communicate with one another.
            -the purpose of buses:
            *is to reduce the number of pathways.
            *is to communicate between the components.
            *by carrying out of communications over a single data channel.
           -if only two hardware components communicate over the line, it is called hardware port.
           -such as:
           *serial port-represents the first interfaces to allow computers to exchange information with the outside
                             world.
           *parallel port-like serial port are built into the motherboard. It is also data transmission involve sending
                                data on a several channel.
*registers-are special memory locations that can be accessed very fast. Three registers are shown:
                *instruction register-is a part of CPU's control unit that stores the instruction currently being
                                              executed or decoded.
                *the program counter-is incremented automatically after fetching a program instruction, so that
                                                 instructions are normally retrieved sequentially.
                *accumulator-is a register in which intermediate arithmetic and logic results are stored.

LAPTOP is a personal computer for mobile use. It is also integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device and speakers into a single unit. And it is powered by mains electricity, can be used away from an outlet using a rechargeable battery.


FILE OPERATIONS:
*create- is to bring into being creation or cause to exist. You can  
              create a files, a documents, an important details, a folder      
              and etc.
*delete-is to remove by striking out, canceling and to eliminate.
*close-means to seal up, shut off, or make something

computer

Computer is a device that accepts information and manipulates it for some result based on a program it is also a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations.It has ability to store, retrieve and process data.You can also use 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.

Based on my own knowledge about Computer.You can communicate with other people or you will h ave a conversations for those people, and when it comes to the Computer they will know often a lot more than those of us. We all know that the Computer is a high technology because it can gives us our needs for educations and learn a lot of things.
   Computer is advance of technology not only develop the positive sides  but also the negative ones. It can create a difficulties to users because the important data will be lost if the users cannot manage well or there are lots of hackers that are eager to take advantages in this field, can provide effectiveness in many ways.
