Software Compatibility

A lot of softwares are been developed to enhance the effective use of computers. Nevertheless, we need to enquire about the compatibility of this softwares.
Some of the things to consider are:
1. Minimum memory size.
2. Minimum processor speed
3. Screen resolution requirement.
4.Sofware bit version. e.g you should not install a 64-bit software on a 32-bit Operating system.
. . . amongst others.

System Maintenance

Hello Everyone, i will like to remind you of the importane of maintaing your computers. this should be a routine if you care or/and value your computer system(s).
Some of the activities involved are:

1. Running Disk Defragmentation at least once a week.
2. Cleaning unused icons once a while.
3. Backing up your disk content at least once a week.
4. Updating your Anti virus software.

 I've got to go, see you all later.

WhatZz up?

Wow! It's been a long time i blogged; I haven't really gotten the time.
How are you doing? And how was your day? It is Nice to be back!

I noticed that most people do not bother to exploit the Interactivity of this site. Come on! your comments, opinions, and suggestions are needed to make the initiative behind this planet effective and vectorial.
I'm willing to be of any help to you concerning Computer Engineering.
Hope to get your reply soon.

SOFTWARE INSTALLATIONS

The table below contains the minimum system requirements for various operating systems. study carefully:

MINIMUM HARDWARE REQUIREMENTS FOR INSTALLATION OF COMMON OPERATING SYSTEM.

Operating system	Hard disk capacity	RAM	Processor speed
Windows 98/ME	2GB	32mb	100mhz
Window 2000	3GB	64Mb	150Mhz
Window XP professional/unlimited	5GB	128Mb	300Mhz
Windows Vista	5GB	512Mb	1GHz

Memory units

It is very important that this is known and understood; Memory units are used in measuring the storage capacity of computer storage devices.
They are as follows;
1 bit (a binary digit i.e 0 or 1)
8 bits = 1 byte 1024 bytes = 1 kilobyte(KB)
1024 kilobytes = 1 megabyte(MB)
1024 megabytes = 1 gigabyte(GB)
1024 gigabytes = 1 terabyte(TB)
1024 terabytes = 1 petabyte(PB)

Sizes in "bytes" Kilobyte (KB) = 1,024
Megabyte (MB) = 1,048,576
Gigabyte (GB) = 1,073,741,824
Terabyte (TB) = 1,099,511,627,776
see ya!

SYSTEM TROUBLESHOOTING

TROUBLE-SHOOTING: this is the process of inserting a problem, so as to pin-point the real cause. To be an effective troubleshooter, you must approach the problem in an organized manner. There are five phases of troubleshooting.

•     Define the problem
•     Zero –in on the cause
•     Conduct the repair 
•     Confirm the result
•    Document the result

Defining the problem: for you to be able to tackle the snag, listen to the client and co-worker i.e. the computer user.

He/she is your source of information. Don’t assume you know.

Questions such as the following can be asked:

•  Was the computer working properly?
• When did you first notice the problem? 
• Was the computer moved recently?
• Have you made any changes to the hardware or software?
• Can you reproduce the problem?
• What does the error look like?
• Were there any error messages?
• Are there current back-up of the system and data files available?

Zero –in on the cause : this involves the process of insolating the problem the best method in this regard is to eliminate any obvious problem and work fro the simplest problem to the more complex.

Repair or replace: after locating the problem, you can either repair or replace the defect. If the problem is software related, be sure to record the “before” and “after” changes

Confirm result: no repair is complete without confirmation that the job is done. Confirmation includes two steps;

1. Make sure that the problem do no longer exist and ask the user to test the solution and confirm the client’s satisfaction
2. Make sure that the fix did not create other problems.

Voltage Distribution on a computer system

The power supply unit of a computer system unit can be defined as the unit which energizes the circuit of the system.

There are basically two types of power supply unit in a computer system.

AT [advanced technology]

 This refers to the computer supply type which makes use of two pin connector [P8 and P9]. The two pins are attached directly to the motherboard to supply a  d.c to the motherboard. The AT power supply makes use of manual switching circuit.

When 220/240v a.c is supplied via the wall socket into the computer system, the power supply unit of the computer system step-down and converts the voltage to 12v d.c.

NOTE: when installing the connectors on the motherboard, the two black wires [from the P8 and P9],must face each other.

Direct current [D.C]: This refers to current that flows in one direction

Alternating current [A.C]: this refers to current that flow in a sinusoidal way

ATX Power Supply Pinout

ATX [advanced technology extension]: this is the power supply unit type which is found on most modern systems. It supplies 12v d.c into the motherboard which is then distributed evenly   as outlined below. The two connectors are joined together unlike that of AT in which the two connectors are separated.

Below is a table displaying the voltage distribution on a Typical Computer System.
