The concept of Computer Systems CPU ( Central Processing Unit ) / Processor Input / Output Memory ( RAM and ROM ) AMD CPU @ jagadreview.com INTEL CPU @ cpu-world.com The main part of the computer because the processor serves toregulate all activities
Konsep Sistem Komputer Input/Output Memory ( RAM dan ROM ) Memory function for store the data and programs. Various types of memory is the fastest access to the too late. Based on the speed of access can be made memory hierarchy as in table 1.1. follows. CPU ( Central Processing Unit ) / Processor
8 Register Memory Cache Memory Main Memory Secondary Memory Is a type of memory where the fastest access speed, memory iscontained in the CPU / Processor Memory ( RAM and ROM )
9 Register Memory Cache Memory Main Memory Secondary Memory Limited-capacity memory, high speed is more expensive than main memory . Cache memory is there between main memory and processor registers, so that processors do not work directly referring to the main memory so that performance can be improved. Cache Memory There are two kinds: Cache Memory which is located on the internal processor, cachememory of this type of very high-speed access Chace Memory, which are outside of the processor, which is locatedon the motherboard. Memory ( RAM and ROM )
10 Register Memory Cache Memory Main Memory Secondary Memory Memory function for store data and programs. Main memory types: ROM (Read Only Memory) is memory that can only read data orprogram . On your PC, ROM contained in the BIOS (Basic InputOutput System) is located on Mother Board which functions forsetting the peripherals available on the system. Chace Memory,located outside the processor, which is located on the motherboard RAM (Random Access Memory) which has the capacity for conversion of data or programs stored on it. Memory ( RAM and ROM )
11 Register Memory Cache Memory Main Memory Secondary Memory An additional memory function to store the data or programs . Example : Hard drive, Floppy Disk etc. Memory ( RAM and ROM )
Input / Output Unit is part of the computer to receive data and display the data after processing by the processor. Input / Output unit is divided into two parts, namely: Port I/O Peripheral I/O CPU ( Central Processing Unit ) / Processor Input / Output Memory ( RAM dan ROM ) The concept of Computer Systems
Port Paralel (LPT1 atau LPT2) Port Serial (Com1, Com2 ) = Port AT / PS2 USB Port Port VGA Port Audio 13 Input / Output Port I / O
The first category consists of equipment that perform input and output operations, this category includes the keyboard, trackball, mouse, printers, and video display. The second category consists of equipment in priority to the secondary data storage, where storage is mainly provided by the computer's main memory. 14 Input / Output Peripheral I/O Peripherals is something that refers to the external equipment is connected to a computer. Computer peripherals can be divided into two categories based on function .
FUNCTION COMPONENTS / PHERIFERALPC Component - component of the PC are: CPU (Central Processing Unit) atau Processor Motherboard Memory Casing dan Power Supply Keyboard dan Mouse Expansion Card
16 FUNCTION COMPONENTS /PHERIFERAL PC Printer The printer is an output component is classified as a Hard Copy Device . Which is a device used to print the output of the process performed by the computer either text or graphics directly using paper or other media.
Dot Matrix Printers, The workings of this printer with printhead slammed into the ribbon to form characters on the print media. Inkjet Printers, How it works, with a squirt of liquid ink onto paper. Laser Printers, printers for computers that use light diode technology to obtainsmall particles of toner cartridge to the paper. This printer has a high speed. 17 PRINTER There are three types of printers in the market: Dot Matrix Inkjet Laser
Conektor Paralel Port USB Port . 18 PRINTER According to the printer connector there are two kinds :
19 FUNCTION COMPONENTS /PHERIFERAL PC Scanner Scanner adalah suatu alat elektronik yang fungsinya mirip dengan mesin fotokopi , scanner hasilnya ditampilkan pada layar monitor komputer dahulu kemudian baru dapat dirubah dan dimodifikasi sehingga tampilan dan hasilnya menjadi bagus yang kemudian dapat disimpan sebagai file text, dokumen dan gambar .
Component - component of the PC are: CPU (Central Processing Unit) atau Processor Motherboard Memory Casing and Power Supply FUNCTION COMPONENTS / PHERIFERALPC
CPU (Central Processing Unit) or Processor Processor / CPU (Central Processing Unit) is a computer brain . Processor can be classified from differences in the amount of data bus. Example there is an 8 bit processor, it means the processor has 8 data bus, processing speed and the number of cores you have. There are several processors to PC manufacturers , like Intel, AMD, Cyrix, and IDT Winchip .
MOTHERBOARD The motherboard is a board where all the devices installed startingfrom the processor, memory, expansion slots, etc .. That should be considered in selecting or assembling a computer is that every motherboard has different specifications for each brand or type that is: Processor Socket RAM Capacity and how many slot ready PCI Slot Is Support for AGP motherboard for VGA card, AGP support will be more profitable to stock if desired increase in graphics capabilitiesof computers by installing a AGP card . Chipset adapter card is available onboard
MOTHERBOARD
MEMORY RAM ROM Random Access Memory In accessing data stored in memory is done by random ( Random)rather than sequential manner (sequential) as in the streamer. This means for accessing the memory elements located anywhere within the module, will be accessed in the same time . Based on the manufacture, RAM classified into two main parts,namely : Static RAM Dynamic RAM
MEMORY ROM RAM Read Only Memory Data is written in the memory can not be changed with the normal process and can only be read only. It is stored in the BIOS when the computer starts and the first steps is known as bootstrapping. This type of ROM include : PROM (Programmable ROM) EPROM (Erasable Programmable ROM) EEPROM (Electrically Erasable PROM)
CHASING and POWER SUPPLY CASING The casing is a box which contain the processor chip (CPU),memory chip, and comes with a motherboard and power supply. Somet imes the casing also contains a secondary storage device . Casings found on the computer desktop or tower models. The casing contains the power supply and fan to prevent excessive arrow. POWER SUPPLY
CHASING and POWER SUPPLY CASING used as a tool to convert AC to DC current so that the computer can work. Owned power capacity power supply to determine the ability of the peripherals can be connected to the computer. Selection of anappropriate power supply is also very necessary to get the maximumperformance of your computer. POWER SUPPLY
IDENTIFICATION OF THE HEALTH AND SAFETY . Definition philosophy , A thought and effort to ensure the integrity and perfection of bothphysical and spiritual labor in particular and people in general, worksand cultures towards a just and prosperous society Science , Science and its application in an attempt to prevent possible accidents and occupational diseases . Practical : protection efforts so that workers are always in asafe and healthy during a work wrought work, and do the work in the workplace and the source and production process can be safe andefficient in its use. Target Preparation and Safety in Assembling PC.
IDENTIFICATION OF THE HEALTH AND SAFETY . Definition Guarantee the physical and spiritual perfection as well as the work oflabor and culture Prevent and reduce accidents and (Work Due to Illness ) guarantee : Every labor and other people who are in the workplace have the protection of the safety Any source of production can be used and used safely and efficiently The production process runs smoothly Target Preparation and Safety in Assembling PC.
IDENTIFICATION OF THE HEALTH AND SAFETY . Definition Screwdrivers, pliers, AVO meter (if any), solder, tin solder, insulation, wire rope and record evidence. Current and voltage measurement is only performed if the components used is the old component is still unknown whether or not AVO meter should not use if the motherboard is still good, because you do not know where the points are a point of measurement . Carelessness in this regard could lead to deadly consequences . If you already know the power source voltage of the power supplylook at the computer (located in the cashing / computer box) if it is set on a scale voltage corresponding to the electrical voltage at your place or not. Target Preparation and Safety in Assembling PC.
