Safety Procedure For User During
Computer Assembling
• Keep the work area free of clutter and clean.
• No drinking or eating in the work area
• Remove all jewellery and watches
• Make sure fre extinguisher and frst aid kit are available
• Make sure the power is of and the power plug has been removed from the socket when working inside computer.
Safety Procedure To Prevent From
Data Loss and Damage
(Anti Static Precaution)
• Electronic equipment is most vulnerable to ESD or
electrostatic discharge. A safety measure to avoid loss of data or damage is by using anti-static wrist strap when handling electronic equipments
• Other than that, using anti-static mat ensures
equipment pulled from computer is protected when set aside.
• Any equipment not in the computer must be stored
in anti-static bag, a specially designed bag that sheds whatever static electricity you have when you touch it thus preventing damage to the
Safety Procedure To Prevent From Data
Loss and Damage
(Electrical Precaution)
•
make sure all power cords are disconnected
•
This is particularly important if you have one
of the latest ATX-based cases where power is
constantly fowing to devices in the system,
even when you think they are switched of.
•
This power supports the case on-of switches
• ensure that network and telephone lines are not connected to PC
• Peripheral devices such as the keyboard and mouse should also be disconnected, just to be extra safe. • Dismantling discrete electronic components such as
your Power Supply or Monitor is dangerous. They contain high voltage capacitors, which can cause a severe electric shock if you touch them. These hold a charge even when the unit is not plugged in and are capable of delivering a fatal shock

Loss and Damage
Types of Power Disturbance
• Noise – any unwanted signal usually varying quickly that is mixed with the normal voltage entering the computer.
Noise is caused by external devices such as fuorescent lighting, radios and television as well as components within the computer. Generally not a risk to hardware, software and data.
• Undervoltage – occurs when power supply drops more than fve percent below the normal volts and can cause data loss but generally doesn’t cause equipment damage.
• Overvoltage – also known as power surge occurs when incoming power increases more than fve percent above the normal volts. A momentary overvoltage called spike occurs when overvoltage last less than one millisecond.
Computer Ports
• Port is the point at which a peripheral attaches to or
communicates with a system unit so that the peripheral can send data or receive information from the computer.
• port is a specialized outlet on a piece of equipment to which a plug or cable connects
• Hardware ports may be physically male (unusual, since protruding pins easily break) or female (usual on
equipment).
• hardware ports can almost always be divided into two groups based on the signal transfer:
• Serial ports send and receive one bit at a time via a single wire pair (Ground and +/-).
Computer Ports
• After ports are connected, they typically require
handshaking, where transfer type, transfer rate, and other necessary information is shared before data are sent.
• Hot-swappable ports can be connected while equipment is running. About the only port on
personal computers that isn't hot-swappable is the keyboard PS/2 connector
• Plug-and-play ports are designed so that the

USB
• USB (Universal Serial Bus) is a specifcationto establish
communication between devices and a host controller (usually personal computers).
• USB is intended to replace many varieties of serial and
parallel ports.
• USB can connect computer peripherals such as mice,
keyboards, digital cameras, printers, personal media
players, fash drives, and external hard drives. For many of those devices, USB has become the standard connection method.
• USB was designed for personal computers, but it has
become commonplace on other devices such as
HDMI
• HDMI (High-Defnition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data.
• It represents a digital alternative to consumer analog standards, such as radio frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA.
• HDMI connects digital audio/video sources—such as set-top boxes, Blu-ray Disc players, personal
SATA
•
The
serial ATA
(serial advanced technology
attachment), or
SATA
computer bus, is a
storage-interface for connecting host bus adapters to
mass storage devices such as hard disk drives
and optical drives. The SATA host adapter is
integrated into almost all modern consumer
laptop computers and desktop motherboards.
•
SATA ofers several compelling advantages over
the older parallel ATA (PATA) interface: reduced
cable-bulk and cost (reduced from eighty wires to
seven), faster and more efcient data transfer,

Computer Assembling
Procedure
1. Install power supply unit after
disassembling the casing panel.
2. Install the processor / CPU into the
socket.
3. Place heatsink and fan onto the
processor after applying the thermal
paste. Connect the fan to CPU fan
connector.
4. Install memory (RAM) into memory
slot.
