WEEK 1: ice breaking session and computer
This first class was an ice breaking session which was about a briefing
on computer internet and trying to introduce this new subject to the
students.During this introduction we have learn the objective of this
topic and also we have been given the rules of the class and the program
about all the assessments components and exams and the method how the
class will be given: face to face lecturer,group activity,on line
activity and the presentations.To be honest this first meeting has been
very helpful for me. because for the first time i was a little bit frightened about what i heard from my friends, after all i have noticed that this subject have not any difficult face but it has a similarities with information technology which subject i took during the previous trimester.
After the class session we had a tutorial class in the lab which was to test our typing skill to know the number of word that we can type in a minute we have been asked reach at least 40 words in a minute which I reached after many tentative.
In conclusion during this first week,we did not do many things but we knew some basics things about computer internet and which are very important and helpful.

In conclusion during this first week,we did not do many things but we knew some basics things about computer internet and which are very important and helpful.
Talking about information processing cycle we have been shown that a computer converts data to become information and the processing requires a group of instructions for example programs and software.
The components of computer are:hardware(the physical part),software(programs) and others(people,data/information).
Computer Hardware Basics(Number systems-Decimal,Binary,octal,hexadecimal)
WEEK 2: The basic computer hardware architecture
After learning all the basic of computer internet, we started to reach the important side of the course which was about computer hardware architecture.During this second week my feeling was so different from the previous week because here i was aware and i knew much about the subject,we learned about the pre- computers and the early computers that the ancient civilization had the ability to count and compute and abacus the earliest recorded calculating devices. Computer has been invented by many people saying that it has not be invented in one time. computer has been made with different inventor such as french mathematician invented a calculating machine, German mathematician invented the first true multiplying calculator in 1670. So based on french mathematician machine, french silk weaver invented the jacquard loom that weaved complex designs in 1801 and an English mathematician, philosopher, mechanical engineer originated the idea of a programmable computer in 1820 all these five efforts have given birth to computer .
Talking about computer we can enumerate five generations: eniac, transistor, integrated circuit, single-chip processor and the artificial intelligence.
in a computer we have five components like processor, memory, input and output system and data-path and control with the communication, collection, of parallel wires or control signal and the center of manipulation.We have learn about the six categories of computer such as embedded, personal computers, mid range servers, main frame, and supercomputers. In this session class for week 3 we have seen about system unit that is a case it contains electronic components, for instance processor, memory module, expansion card and ports, connectors. We have learn about the CPU it's act like a brain of any computer system. The registers is a special purpose, high speed, temporary storage and located inside CPU. After this, we have been talking about main memory that is consist of two types are RAM and ROM. Ram mean that any word in the memory can access without go through into all the order word and it can loose its contents when the power is turned off, but for Rom the contents can only read and write the data on the chip so it has volatile memory.
After all, we learned about input devices, output and storage devices. Input is any data and instructions entered into the memory of a computer and also the hardware components that allows users to enter data for example, the keyboard, pointing device, pointers, game controllers, digital camera, voice input, video input, scanners, bio-metric input and terminal, that are Post, ATM and DVD kiosk. About the output device is a data that has been processes into a useful form. It's any type of hardware component that conveys information to one or more people like, display devices, printers etc. At the end the types of storage we have hard disks, flash memory storage, optical discs and the other types like tape, magnetic cards, smart cards etc. So, storage is the physical material on which a computer keeps data, instructions and information.
WEEK 3: Describe the role of computer software
hello again welcome to our new topic!!! for this week 3 we have learnt about software. most of us use computer, but they don't know what is software. For that we can define Software as an intangible part of a computer that it tell what a computer supposed to carry out, drives the hardware and collected the related data. It is divided into 3 types such as system software , application software , and programming language, therefore it layers from the user until the computer hardware. Also, the type of software we have operating system and utility programs that can stand alone OS to complete on a computer such as DOS , windows , Hac Os , Unix, Linux, server OS that supports a network for example windows NT, Unix , Linux , Solaris , wetware and embedded OS to built in on Rom chip mainly for mobile like windows CE, palm OS , blackberry and android. For utility programs just that most users buy additional programs manage , search, install, view, backup and the protecting of your computer.
we learned also about the programming language which is a set of words, abbreviations that enables a programmer to communicate instruction to a computer. We need a programming language for the development process by the high level language compiler to assembly language and to the machine language.
Thus, in the higher-level language the evolution are more powerful than assembly language. There are three generations, third, fourth and fifth. The third one is the first one to use trough English, the fourth is easier to use than 3GLS it may use a text based environment,using graphical tools and the last is used in issue of debate in the programming community.There are many HLL such as :procedural, functional,object-oriented and rule-based the most important for the language depends on how humans best think about the problem and also some of the other considerations like efficiency, compatibility with existing code and availability of translators. We have interpreting and compile but their difference is like compilation can be expensive the programs run faster but interpretation more ability to perform their diagnostic at run time.
Finally, at the end of this week we have been studying about the application software which is just a consisting of programs designed to make users more productive. This application is available in a variety for instance in a forms of package software to custom software in web application to open source until public domain software and the application was specify in proprietary software and off the self software. Thus, software has many applications such as work group, enterprise, business graphic multimedia, home and communication.
Moreover, we need to buy some software if we want to get it for example online, through catalogs, at auction and also the license of software if it is an agreement between the user and the software company,
So that we need to install it by following the instruction which will appear in the screen after installing the software disc.After all the installation completed ,most of the time we need to restart the computer to be able to use the application.
WEEK 4: The typical ways of networking computers
In the beginning of this week i have learnt so many things in this ICT subject. Now my lecturer continue to teach with the basic networking concepts. As the picture show, i can see how computer do its' network. It seem so busy and hardworking thing more then people. Here is a sorts of what computer network is. It is simply a group of interconnected computers. It must has two or more computers are connected via hardware or software, and able to communicate with each other. The most important that network may be nearby to each other or at different geographic locations. Such as the internet, ATM, school network, e-banking, home network and etc. I still remember, when my lecturer show his example in this topic. But the topic give me more understanding in signal side.
I have learnt` network medium, physical medium, and wireless medium. I am sort interest on medium word so let me give my opinion in network medium it's a computer that share access to common network medium that carries signals from one computer to another computer. Medium may also be physical cable (twisted pair, coaxial, or fiber-optic) and wireless. Next, let we move to physical medium. Actually this subtopic easy to understand. May in your mind set physical is the appearance of something that we can touch and see, such as open wire, copper wire and etc. When talk about wireless, it can bring us to the world and easy to communicate in this world. Its' work without wired but can use at every part of this world as long it has the signal. Such as mobile phone and internet.
I think this topic will not complete without going through in types of network. They are, network in small geographical area (room, building or a campus) is called LAN (Local Area Network), network in a city is call MAN (Metropolitan Area Network), and network spread geographically(Country or across Globe) is called WAN (Wide Area Network). Actually wired give a huge help to connect the computer going on.
WEEK 5: Demonstrate the application of MS Windows computer operating system
All my life i was asking myself about the secret or the hidden side of windows operating system. In this week 5 we have learned all about windows operating system, how its works and its components
his week almost in the end of the lecture. Actually, i cannot say more about this topic because all we have learn were more practical.
WEEK 6: Word Processing Skills: MS Word Basic
Salam !!! welcome,in this week 6 we have been leaning about Microsoft word ,what is microsoft word and how to use Microsoft Word.during this week had an amazing face to face lecturer because all the classes were moderating by our lecturer in charge but he was choosing randomly the student to come in front and use microsoft word.while using micrsoft word our lecturer was explaining and showing us all the element and the system of this application,the aim of choosing the student was to give us more chance to understant the topic and apply it.They are some of its components such as, document window, ribbon, mini toolbar, quick access toolbar,shortcut menus, key tips, text basic, basic text operation, basic tasks,and formatting. How ever, it make me more expert in order to use the Microsoft word. In conclusion i am happy to say that now i know all the secret of microsoft word and i can use it without any difficulty.
WEEK 7: : Microsoft Excel basic
Here we are again !!! in this week number 7, after learning Microsoft word we are now with Microsoft excel which is an electronic spreadsheet program that can be used for storing, organizing and manipulating data.
As we know,preadsheets are often used to store financial data. Formulas and functions that are used on this type of data include:
- Performing basic mathematical operations such as summing columns and rows of figures.
- Finding values such as profit or loss.
- Calculating repayment plans for loans or mortgages.
- Finding the average, maximum, or minimum values in a specified range of data. By the way, i can say that Microsoft excel is an important tool which is very helpful
WEEK 8: : Microsoft Power Point Basic
In this week the class was about microsoft power point we said that,Microsoft PowerPoint is an application used to create presentations,
such as those for business and academic environments. You can understand
PowerPoint by realizing that it's a tool for one person or a team to
clearly communicate key points to many other people. The exact way
PowerPoint is applied depends on the goals for the presentation in the
workplace, classroom or other setting.Now in AIU most of our courses are on power point and all the presentation of the students are on it.
After all, even if i had some knowledge about this tool, i have learn more during this week.
WEEK 9: The Internet : History and the Underlying Technologies
hello!!! In this week we just learned about the history of the internet , we have been saying that internet is the largest network in the world that connects hundreds of thousands of individual networks all over the world. We have use the internet for many application such as sending emails, upload or receive files, surfing the web etc. And at the end its about the firewall is a security system that acts as a protective boundary between a network and the outside world now everywhere internet is a fundamental tools: education,health,finance,sport and so on we are seeing the advantage of internet. Finally i can conclude this week by saying that i was really happy for learning about this amazing network.
WEEK 10: Group assessment
Hi! in this week 10 we didn't had any real class all we had was a group assement. we have been separated into a group of 3 or 4 student and givent a sheet of paper which was contening a number of question those questions were about all the 9 previous topic we have been studying this assessment was to see the level of understanding of the students.After this first teaching day of the week, we had a lab test which was about power point,creating slides and applying some applications asked by the lecturer.
CONCLUSION:
In conclusion i can say that during this trimester i have learn may things which are very interesting and helpful for me. This trimester, i remember my feeling was so down when i started the class but now i can say that i have got 80% all the things taught in class and it is a success for me.
At the end i would like to thanks Mr AZZAMOUDINE for all is efforts,but also all my classmates.
THANK YOU!!!!!!
