Software

Assalamualaikum...

Hai!! Software is the third topic in this subject. We have learned this topic in week 3. Software is  a collection of instructions that enable user to interact with computer or have the computer perform specific tasks for them.

Software has divided into 3 categories which are system software, application software and programming language. System software is a type of computer program that is design to run a computer's hardware and application programs. There are 2 types of software which are operating system and utility program.

There are so many sub-topic in this topic. When I read this topic I feel like I'm going to vomit because there are so many things that confusing me. Also, I felt so tired and my brain couldn't absorb what have I read. However the topic is too many but I have tried to understand and finish reading until the end of the topic.


In class, Mr. Azamuddin has shown us the video about system backup and system restore. Actually, I didn't get what the video is all about because I'm not pretty good in listening.

Assalamualaikum..

Hai!! For this post, I'm going to continue about the previous post which is Computer Hardware. But today, I'm going to focus more on computer rather than hardware.


Computer has 5 generation. The first generation (1940-1956) is Vacuum Tube. Second generation (1956-1963) is Transistor while the third (1964-1971) is integrated circuits or micro chip. The fourth generation (1971-present) is microprocessor and the last one (present and beyond) is artificial intelligence.


Computer architecture is the art that specifies relations and parts of a computer system. It consists of processor, memory( RAM/ ROM ), input, output, datapaths and control.  There are 6 categories of computers which are embedded computer, mobile computer, personal computer, midrange servers, mainframe computer and supercomputer.


System units is a box-like case housing the electronic components of a computer that used to process data. In a simple word system units is the main part of a desktop computer. It includes motherboard, CPU, RAM and other components. The components are processor, memory module, cards, ports and connectors. System units also known as 'tower' or 'chassis'.

The examples of system units and it components

Overall, I think this topic is so simple but there are so many components and the terms that made me confuse. But all the confusion were disappear after I've done wrote this topic. Hehe!! See you in the next post.

Computer Hardware 1

Assalamualaikum...

Hai!! This is my second trimester in foundation. So, for ICT course, I chose to study Computer Internet in this trimester. Actually, I have taken Literacy for this trimester but when I came to class, I realized that many students have taken the subject and the class was seem very crowd. Then, I came to Computer Internet class to see the situation and it was cool and more relaxed.

Before Mr. Azzamudin teach us the first topic in Computer Internet. We had been briefed about computer by him. Computer is a programmable machine that perform tasks or calculations according to a set of instructions or programs. Also, Mr. Azzamudin explained to us about components of computer (hardware and software) and the elements of computer (input, output, storage, communication, and processing). 

Computer processing cycle

Next, Mr. Azzamudin taught us about computer data representation and numbering system. Data representation is a methods used internally to represent information stored in computer. Computers store lots of different types of information such as texts and numbers. Computers work with a binary number system that consists of only two digits which are 1 and 0. One digit in binary number system is called 'bit' and a combination of 8 bits is called byte. There are 4 types of number system which are binary, octal, hexadecimal and decimal.

Characteristics of each numbering systems

Conversion from decimal into binary

Conversion from others numbering system number into decimal

This topic is quite easy but I got confused about numbering system at first. I got confused how to convert them into others number system. However, Mr. Azzamudin gave us many exercises how to convert the numbering system. Lastly, I didn't get confused at all.
