NO Technology

What would happen to the world if there's NO Technology

Just imagine a day at school without technology. How would you contact with your friend, teacher or family at another location? Can you access, build, revise or repair without computer or power supply? Can you run tests, analyze data or control variables without a single technological tool? How did you get to learn in school with not heat or light to begin with?

This scenario may seem ridiculous, but I want to make it clear that technology have already affects every aspect of our life. It makes it possible for the work that we do to be more accurate, more efficient, more effective and more supportable.

If we're staying in the house with no TV, no Internet, No phone, no fan or air- conditional, no refrigerator and etc., what will happen to us? We will become lazy, uneducated and useless.

If we go by this, we would only survive at the level of animals. We would not even be able to use rocks to cut flesh open, since that is also a technology. Spears, bows and arrows, hammers and even slingshots would not be used since it is a technology. We would not be able to survive if we went back to before the Neolithic age (New stone era), when we had a technology. We would probably just kill small animals with our bare fists and eating them raw without cook it since fire is a technology and sleeping in the ground and so on. If we cannot even use the six simple machines, then the humanity is doomed to eventual destruction since humans are prepared for survival with mental capability and not physical capability.

Today, we will collaborate using technology to share information that impacts our decisions offline. And we collaborate to consume, we collaborate to entertain ourselves, we collaborate for experiences, for learning, for exercise, for causes, for experiments, for business and for living. Some technologies have been around for a while. Others have only recently been developed.

Technology has always been focused on improving our lives but more recently the technology has made real-time, location-based collaboration possible. Specifically, mobile technology now allows us to interact with online communities from anywhere at any time. It has allowed us to experience the world around us not only through our own knowledge and resources, but through the knowledge and resources of the people around us.

Think about what the world could look like as collaborative technology continues to grow. What will the world look like when you can rely on normal human beings instead of big businesses to provide you with what you need? Not only will the economy be more efficient, but our lives will be enriched because we’re connecting with real people who are all part of one global, collaborative community.

In other word preventive maintenance saves time and money, improves productivity and secures data from exposure to hackers and viruses from internet use. These activities can include regular inspection along with solving any discovered problems and regularly schedules parts changes. In other word preventive maintenance saves time and money, protects your data, improves computer performance and prolongs computer life.  Preventive maintenance can be divided into 3 maintenance.

• ·         Mechanical maintenance

• ·         Electrical maintenance

• ·         Software or hardware disk maintenance.

Next is how to do a PC preventive maintenance. Here I will give the PC preventative maintenance checklist.

Straight Through & Cross Over

28th April 2012, We were given our second activity which involved with making RJ45 (Twisted Pair) cable into Straight Through and Cross Over cable.

Twisted pair is A type of cable that consists of two independently insulated wires twisted around one another. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. While twisted-pair cable is used by older telephone networks and is the least expensive type of local-area network (LAN) cable, most networks contain some twisted-pair cabling at some point along the network.

After we finish with rearrange the color, we need to connect the wires with the clip.

World War 1 Technology

Big Bertha

The Big Bertha was a German initiative put into action before and during the First World War, where artillery started becoming more mobile than in previous wars. the name itself "Big Bertha" is usually associated with many World War 1 large caliber guns.

The female name "Bertha" comes from the descendant of Krupp steel which an arms manufacturer. The Big Bertha could lob 2,200lb shells over 9 miles. The Big Bertha took a crew of 200 men over six hours to assemble and disassemble the weapon.

Its most notable action was against a series of undefeatable Belgium forts. the Big Bertha's lay waste to the forts, demoralizing the allied forces and convincing the Germans to continue exploration into more mobile and more powerful howitzers which included the "Paris Gun where though highly inaccurate which the mighty howitzer that terrorized Parisians from over 70 miles away showing French countrymen that their country was not safe from the war.

This was so effective, the Big Bertha fire killed hundreds and thousands of men. It also blew the ground, which made hiding much more difficult.

Technical Data

•     Caliber: 420mm (16.5 in)
•     Range: 12.5Km (7.7 miles)
•     Projectile Weight: 1763 lbs
•     Muzzle Velocity: 400 meters/second
•     Length: 6.72 meters
•     Crew: 285 men
•     Fire speed: 8 rounds per hour

Our Third HT Assignment

Assignment 3

 Here, We been given our third assignment. On this assignment assignment, we were required to do 2 task. Our first task is we need to do a CLASS ACTIVITIES which given by our instructor, Sir Ahmad Muzhaffar. For this Class activities, we were required to work as a group to assembling and disassembling of CPU. This Class Activities was held on 14th April 2012. As you know, I from One Brunei group along with Akmal Hafizh, Sarinah and Fiona.

Class Activities- Assembling and Disassembling the CPU component 

Each group can choose only one CPU

Front VIew

Back View

We using PC tools to assembling and disassembling all the component in the CPU. The PC tools was provided by college. I will explain the uses of each tools in next post.

PC tools

First, we open the CPU case by removing all the screw that attach in the CPU case with provided tools. We open the CPU on the table so that make our work more easier by remove all the component inside the CPU except Motherboard and Power supply.

View from inside the CPU

Before we take out the component, make sure you take picture all the component inside the CPU so that it we wont forget where to connect the component. Because it will make you confuse just looking at cable. After that we remove the 5 component inside the CPU.

 Here is the component that we already take out from the CPU.

Floppy Disk Drive

CD Drive

Harddisk

Heat Sink

CPU Fan

 Next, after all the component been take out, we need to assembling back the component into the CPU.

 

Finally, after we assembling all the component in right order, we need to check either it work or not.
