A large building with many computers combined together, making a home for computers in UTM. There were lots of data; whether visually or listening, to process, making the energy drink we have gotten before the amazing tour, worth it.

We first started off with a group photo. The students from faculty of Management and Computer were present at that time. Followed after the group photo, we have gotten a tour of the old computer components. The person who has given us the touring, gave us details of each of the computer parts. He made us understand more of how big the difference and how much, us humans advanced in technology. What surprises me most is, how much they used to give lots of inputs to only have a little output. A memory back then was around 1.44MB, while currently we go to terabytes/petabytes. It is not surprising if we look on their point of view as they do not have much data to store to begin with and as well do not have the right tools for it.

  

After the historical tour, we have gone to the high-tech computers. From small to big, from graphic tablets to a closed sound proof room. I have tried one of their computer (Macintosh) one day and they work pretty well and using adobe illustrator to do logo designs is a visually pleasant sight.

 The high tech computers we had seen and many other we were not able to see; have each of their own purposes. It supports the students and staff members. Every data that has been recorded inside UTM, has been stored in that building and that is the reason to why it is called CICT: center for information & communication technology.

I am happy that I had joined this tour and hopefully be able to see the other rooms that I could not go to one day.

Cpu...Brain of the computer

A CPU or so called the central processing unit, is a part in a pc that does the main calculations, meaning it is the most important element in a computer.

Within the brain, there are two components; the arithmetic unit which does the calculations with normal mathematical operations and the control unit. The control unit is the one which touches the memory unit and does the execution.

The memory unit has three parts; ROM, RAM and cache. RAM is the forgetful part of the memory(volatile), which loses all the data when there is no electricity connected.

ROM is the more memorable part of the memory(non-volatile), where if there is no electricity, it still does not lose the data given.

Cache memory acts like a catalyst, reducing the time taken to receive data from storage/memory.

The programming language generations

Generation languages were used to classify the difficulty of understanding of the language. The newer generations of languages have become very simple and easy to understand

1st generation language 

Is the machine language which consist of 0s and 1s, which gives instruction to work on for hardwares such as processors.

2nd generation language 

Also called assembly language which converts the statements into machine language

e.g

ADD 9,16

3rd generation language 

This generation is the "high level" programming language, such as Java , C or C++

A compiler will change this type of language to machine ones.This generation needs a  decent amount of  knowledge in programming.

4th generation language 

This generation looks more familiar to natural languages and is used for databases.

e.g

EXTRACT ALL CUSTOMERS WHERE "PREVIOUS PURCHASES" TOTAL MORE THAN $1000

5th generation language 

Uses visual interface to create source language that is usually compiles with 3GL or 4GL. Microsoft uses 5gl languages to visualize .eg C# 

Internet of things

Meaning

Is the connection of many of devices with internet. That includes smart phones, washing machines to cars and anything else you can imagine of.

Why is it used?

To make things easier for us and get things done more effectively.

Who uses it and how is it used for?

Devices in homes (Smart Homes)

companies like google make devices that are connected with the internet and make things simpler by touching a button and multiple things turn on/off, e.g lamps.

Wearable devices

wearable devices such as smart watches and smart jackets, do use internet and make things simpler for us.They can be used such as getting news while being outdoors.

Big Data

Description

Big data is a large volume of data, whether organized or unorganized that is being recorded on a daily e.g business day to day basis. The usefulness of these large data is dependent on the organizers or the ones who have the privileges to use those data. It can be used to analyse for looking at patterns and bring out forth a better strategic plan e.g for a business marketing.

Big data comes in many formats such as from emails,videos or financial transactions.

Big data can also be complex, when it come from many different resources, but also helps to make a pattern or connect relationships and so on.

Who uses it and how it is used for?

Manufacturing companies

Data coming from reviewers or many customers, can boost the quality of the manufacturers' products and reduce waste's to minimize the output and maximize their output. That is a key, especially for today's highly competitive market.

Health Care

When data is coming from Patient records, treatment plans and others, and used it very effectively; then they could do things more accurately or sometimes find things that were hidden and could improve the patients care.

Where does it come from?

The sources for big data comes generally from those three categories;

streaming data,social media data and publicly available resources.

My favorite custom made PC

This build is just my for a demonstration for what I wished I would have in the future.
Let us start with the cpu; it is the new AMD Ryzen 7 1800X ; has;
-3.6 Ghz boost to 4ghz
-8cores/16threads
-cashe 4mb/16mb (L2/L3)
-AM4 type
https://www.amd.com/en/products/cpu/amd-ryzen-7-1800x
it is good for multitasking and games

Next is the motherboard which is MSI X370 GPC ATX AM4;

And now we will go with the main attraction and that is the Gpu; EVGA Geforce Titan X 12gb and also it will be two of them and a SLI bridge will connect both of those GPus

Going to RAM , it will be the kingston hyperX fury black 16gb DDR4 memory

https://pcpartpicker.com/product/xhM323/kingston-memory-hx421c14fbk216

Coming next is the storage which would be a SSD 500gb and a HDD of 1TB

https://pcpartpicker.com/product/MwW9TW/western-digital-internal-hard-drive-wd10ezex

The case is an RGB Corsair Crystal mid tower range and the power supply si an EVGA superNova 850watt

https://pcpartpicker.com/product/vbL7YJ/corsair-cc-9011101-ww-atx-mid-tower-case-cc-9011101-ww
This Monster is good for gaming and multitasking such as video rendering and so on.

HDD and SSD , What to choose?

HDD and SSD are both storage drivers, which stores data files or accessing little data transactions.
HDD or also called hard disk drive, has a moving disk which moves like a CD. It stores a lot of data compared to SSD, but usually wears off/breaks when using a long period of time.
SSD also called solid state drive, is a chip that can run software faster than HDDs. It is faster and does not have a disk like HDD, however it is expensive as 500gb of storage is around 150 dollars in present day and also writing on them heavily can also wear the drive.
Both of the drives are reliable and HDDs are being recommended if you store a lot of files while SSDs are used to access software much more faster i.e adobe photoshop.
