INFORMATION SHEET 3.1-1Safety Measures Policies & Procedures in Computer

Configuration

Learning objectives

After reading this information sheet, you must be able to:

1. Define Computer Health & Safety

2. Explain the correct procedures in computer configuration

Occupational health and safety (OHS) refers to the legislation, policies,procedures and activities that aim to protect the health, safety and welfare of all

people at the workplace.

Occupational health and safety (OHS)is a cross disciplinary area concerned

with protecting the safety, health and welfare of people engaged in work oremployment. The goal of all occupational health and safety programs is to foster

a safe work environment. As a secondary effect, it may also protect co-workers,family members, employers, customers, suppliers nearby communities and othermembers of the public who are impacted by the workplace environment.

Safetyis the state of being safe (from French sauf), the condition of being

protected against physical, social, spiritual, financial, political, emotional,

occupational, psychological, educational or other types or consequences offailure, damage, error, accident, harm or any other event which could beconsidered non-desirable.

Health is the level of functional and/or metabolic efficiency of a livingbeing. In humans it is the general condition of a person in mind, body and spirit

usually meaning to Being free from illness, injury or pain (as in good health or healthy).

Quality of Lifeis used to evaluate the general well-being of individuals andsocieties. The term is used in a wide range of contexts.

Every worker has a right to healthy and safe work and to a workenvironment that enables them to live a socially and economically productive life.Safety practices should be learned early and always adhered to when workingwith any electrical device including personal computers and peripherals.

Personal safety while working with PCs

Here are some safety precautions to take before working with any computerdevices:

Before doing anything, listen to your teachers instruction to preventaccidents or any unwanted events that may occur on your workplace.

Do not work on computer when you are wet because you might getelectrocuted.

Do not remove internal devices of the computer when it is turned on.

Be sure not to mix electronic components and water.

Avoid playing or running while inside the room.

Always wear personal protective equipments (PPE) like coverall, shoes with

rubber sole, anti-static wrist strap, etc. Ask for assistance from your teacher when it comes on dealing with

computer devices.

Applying safety measure when handling tools and equipment are necessary

to avoid certain damages.

The student is further expected to maintain good health, to be neat inpersonal appearance and to practice safe working procedures at all time withappropriate equipment.

SOP for Computers

Standard Operating Procedure for Computers

When you get a computer, there is no list of exactly what to do or how touse it. Your manual will describe some basics about the computer but for day-today use you are left on your own to figure out the procedures for use to keepthings going smoothly.

In addition to reducing hardware costs by sharing expensive printers andother peripherals among multiple users, networks provide additional benefits tothe users.

Software and data files can be shared for access by multiple users

Electronic mail (email) can be sent and received Collaboration features allow contributions by multiple users to a single

document Remote-control programs can be used to troubleshoot problems or shownew users how to perform a task

SHARED HARDWARE COMPONENTS

Virtually any storage or output device can be shared over a network, butthe most common devices to be used over a network include:

Printers

Disk drives CD-ROM and optical drives

Modems

Fax

Tape backup units

Network topology

Network Topology signifies the way in which intelligent devices in thenetwork see their logical relations to one another. The use of the term "logical"

here is significant. That is, network topology is independent of the "physical"layout of the network. Even if networked computers are physically placed in alinear arrangement, if they are connected via a hub, the network has a Star

topology, rather than a Bus Topology. In this regard the visual and operationalcharacteristics of a network are distinct; the logical network topology is notnecessarily the same as the physical layout.

Bus Topology

It is often used when network installation is small, simple or temporary. On

a typical bus network the cable is just 1 or more wires with no active electronicsto amplify the signal or pass it along from computer to computer. This makes thebus a passive topology. When 1 computer send a signal up the wire all the

computers receive the information but only one with the address that matchesaccepts the information, the rest disregard the message.

Bus Topology

Advantages:1) Easy to use and to understand.2) Requires least amount of cable to connect the computers together. It is

therefore less expensive than other cabling arrangements.3) It is easy to extend a bus; two cables can be joined into 1 longer cable with aBNC, Barrel connector making a longer cable and allowing more computers tojoin the network.

Disadvantages:1) Heavy network traffic can slow a bus considerably as only 1 computer cansend a message at a time.2) It is difficult to troubleshoot the bus. A cable break or loose connector causesreflection and stops all the activity.

STAR TOPOLOGY

In this kind of topology all the cables run from the computers to the central

location where they are all connected by a device called hub or switch. Eachcomputer on a star network communicates with a central device that resends themessage either to each computer or only to the destination computer, example ifit is a hub then it will send to all and if it is a switch then it will send to onlydestination computer. When network expansion is expected and when the greater

reliability is needed, star topology is the best.

Star Topology

Advantages:1) It is easy to modify and add new computers without disturbing the rest of thenetwork.2) The center of the star network is a good place to diagnose the faults.3) Single computer failure does not necessarily bring down the whole starnetwork.

Disadvantages:1) If the central device fails the whole network fails to operate.2) Star networking is expensive because all network cables must be pulled to onecentral point, requires more cable than other network topologies.

RING TOPOLOGY

In this type each computer is connected to the next computer with the lastone connected to the first. Each retransmits what it receives from the previouscomputer. The message flows around the ring in one direction. The ring networkdoes not subject to signal loss problem as a bus network experiences. There is no

termination because there is no end to the ring.

Advantages:1) Each node has equal access.2) Capable of high speed data transfer.

Disadvantages:

1) Failure of one computer on the ring can affect the whole network.

2) Difficult to troubleshoot the network.

Types of networks

Below is a list of the most common types of computer networks in order of scale.

Personal Area Network (PAN)

A personal area network (PAN) is a computer network used forcommunication among computer devices close to one person. Some examples ofdevices that may be used in a PAN are printers, fax machines, telephones, PDAsor scanners. The reach of a PAN is typically within about 20-30 feet(approximately 6-9 meters).

Personal area networks may be wired with computer buses such as USB]and FireWire. A wireless personal area network (WPAN) can also be madepossible with network technologies such asBluetooth.

Personal Area Network

Local Area Network (LAN)

A network covering a small geographic area, like a home, office, or building.Current LANs are most likely to be based on Ethernet technology. For example, alibrary will have a wired or wireless LAN for users to interconnect local devices

(e.g., printers and servers) and to connect to the internet. All of the PCs in thelibrary are connected bycategory 5 (Cat5) cable, running the IEEE 802.3 protocolthrough a system of interconnection devices and eventually connect to the

The staff computers (bright green) can get to the color printer, checkoutrecords, and the academic network and the Internet. All user computers can getto the Internet and the card catalog. Each workgroup can get to its local printer.Note that the printers are not accessible from outside their workgroup.

Local Area Network

Client/Server Vs Peer-to-Peer Networks

Although every computer on a LAN is connected to every other, they do notnecessarily mean all communicate with each other. There are two basic types ofLAN, based on communication patterns between the machines, calledclient/server networks and peer-to-peer networks.

Client/Server Networks

Every computer has a distinct role, that of either a client or a server. A

serveris designed to share its resources among client computers on the network.The Client/Server is composed of:

Servers

These are located in secured areas, such as locked closets and datacenters, because they hold the organization's most valuable data and do nothave the accessed by operators on a continuous basis.

The server runs a special network operating system such as: Windows NTServer, Windows 2000 or Novell Netware.

Clients

-The rest of the computers on the network function as client. A clientstandard PC that is running an operating system such as DOS or Windows.

Example of Client/Server

Peer-to-Peer Network

In a peer-to-peer network, every computer is equal and can communicatewith other computer on a network to which it has been granted access rights.Essentially, every computer in this network functions as both server and client.Peer-to-peer network can be as small as two computers as many as hundreds ofunits.

There is no theoretical limit to the size of a peer-to-peer network,performance drops significantly and security becomes a major headache on peer -based network with more than 10 computers. Also, Microsoft imposes a 10-

Example of Peer-to-Peer Network

CAMPUS AREA NETWORK (CAN)

A network that connects two or more LANs but that is limited to a specificand contiguous geographical area such as a college campus, industrial complex,or a military base. A CAN may be considered a type of MAN (metropolitan areanetwork), but is generally limited to an area that is smaller than a typical MAN.This term is most often used to discuss the implementation of networks for a

contiguous area. This should not be confused with aController Area Network.

Metropolitan Network

Wide Area Network (WAN)

A WAN is a data communications network that covers a relatively broad

geographic area (i.e. one city to another and one country to another country) andthat often uses transmission facilities provided by common carriers, such as

telephone companies. WAN technologies generally function at the lower threelayers of the OSI reference model: thephysical layer, thedata link layer, and thenetwork layer.

LANs, satellite coverage areas, etc. The key challenge in mobile communicationsis "handing off" the user communications from one local coverage area to thenext. In IEEE Project 802, this involves a succession of terrestrialWireless localarea networks (WLAN).

Global Area Network

Internetwork

Two or more networks or network segments connected using devices thatoperate at layer 3 (the 'network' layer) of the OSI Basic Reference Model, such asa router. Any interconnection among or between public, private, commercial,industrial, or governmental networks may also be defined as an internetwork.

In modern practice, the interconnected networks use the Internet Protocol.There are at least three variants of internetwork, depending on who administers

and who participates in them:

Intranet

Extranet

Internet

Intranets and extranets may or may not have connections to the Internet. Ifconnected to the Internet, the intranet or extranet is normally protected frombeing accessed from the Internet without proper authorization. The Internet is

not considered to be a part of the intranet or extranet, although it may serve as aportal for access to portions of an extranet.

control of a single administrative entity. That administrative entity closes theintranet to the rest of the world, and allows only specific users. Most commonly,an intranet is the internal network of a company or other enterprise.

Extranet

An extranet is a network or internetwork that is

limited in scope to a single organization or entity butwhich also has limited connections to the networks of one ormore other usually, but not necessarily, trustedorganizations or entities (e.g. a company's customersmay be given access to some part of its intranet creating inthis way an extranet, while at the same time the customersmay not be considered 'trusted' from a security

standpoint). Technically, an extranet may also becategorized as a CAN, MAN, WAN, or other type of network,although, by definition, an extranet cannot consist of a singleLAN; it must have at least one connection with anexternal network.

Internet

A specific internetwork, consisting of a worldwide interconnection ofgovernmental, academic, public, and private networks based upon theAdvancedResearch Projects Agency Network (ARPANET) developed by ARPA of the U.S.Department of Defensealso home to the World Wide Web(WWW) and referredto as the 'Internet' with a capital 'I' to distinguish it from other genericinternetworks.

Participants in the Internet, or their service providers, use IP Addresses

obtained from address registries that control assignments. Service providers andlarge enterprises also exchange information on the reach ability of their addressranges through theBorder Gateway Protocol(BGP).

How to install a wired network adapter

To connect to a network, your computer needs a network adapter.Fortunately, most computer manufacturers know that connecting to the Internetor other computers is important to computer users, and they include a networkadapter with your computer.

If you need to add a network adapter, first choose which method you wantto use to install it. Most people prefer to use a USB (Universal Serial Bus)network adapter, because it's easy to install. If you have a portable computer,you might find a CardBus (also known as PCMCIA or PC Card) or CF networkadapter better meets your needs. If you have a desktop computer with the properamount of available space, you may also have the option of adding an internalnetwork adapter.

The instructions you follow to install a network adapter depend on how youconnect it.

How to determine if you have a network adapter

Many newer computers have a network adapter built in thatyou can use to connect to a wired network. If you want to install awired network adapter and aren't sure whether your computer

already has one, look for a network port on the back of the computer. Networkports resemble phone jacks, but they are slightly larger and have eight pinsinside.

To see what kind of network adapters may already be installed in yourcomputer.

1. Click the Start, and then click Control Panel

2. Under or pick a Control Panel icon, click Network Connections

3. Microsoft Windows XP displays your network adapters. If an adapterhas a red X over it, it is disconnected. If the Network Connectionswindow is blank, your computer doesn't have a network adapter.

4. If you already have a network adapter, you are ready to configure yournetwork.

How to install a wired USB network adapter

Once you have the adapter

If your USB network adapter came with software, insert the CD or

floppy disk into your computer, and follow the manufacturer'sinstructions to install the software.

Find an available USB port on your computer.

Note: If you need to move your computer to reach the USBports, you should shut down Windows to avoid damaging your

computer. If you can easily reach a USB port, you need notshut down your computer.

INFORMATION SHEET 3.2-2Procedure in Checking the Faults or Problems

Learning objectives

After reading this information sheet, you must be able to demonstrate theprocedures in checking the faults or problems of computer.

Today's computers have faster microprocessors, more memory and biggerhard drives. When you think about the differences between a Pentium 4 and 386,

you have to conclude the improvement is astounding! But when error attacks ourcomputer we have to do something for the computers to survive. Here are some ofthe common faults and problems that we may encounter:

1. Why computer becomes slow?

You need more memory.

Don't overlook the obvious. Up until recently not having enough memorywasn't a problem. With the price of RAM becoming very affordable, most peoplewere filling their computers with more than enough memory to do the job. If yourcomputer is slow and it has lower capacity of RAM, you need to add morememory to speed it up.

Spyware and viruses

Spyware. It is a software program that intentionallyinstalled on the computer by the user to monitor or spy onwhat the other users of the same computer is doing.

you do realize for them to be effective, you have to keep up todate. By up to date, it means up to the minute.

Virus. A software program, macro or script that has beendesigned to infect, destroy, modify or cause other problemswith computer or software program.

Background programs

When you install new software on your computer, often times you install it torun in the background every time you start up. Most times you do this withoutknowing it. Look at the bottom right hand side of your screen.

If you see several icons there, you have extra programs running and stealingresources. Right click on these and see if you have the option of closing them.Many times, you can open the program and choose an option to keep theseprograms from starting automatically.

Corrupted registry

Any changes you make to your computer effects and actually, it corrupts yourregistry even when you do something positive like remove spyware and you endup with a corrupted registry.

After months of corrupting your registry, it will becomegood. This will, in its early stages, cause your computer to slow

down. In its advanced stages, it will freeze and crash and domore mysterious and troublesome things.
