Pictures related to CSC 134

Salam,...  This morning I would like to post pictures that relate to CSC134 from Chapter 1 until Chapter 5.  It just random...



Chapter 5 CSC134: TYPES OF UTILITY PROGRAMS AND OPERATING SYSTEMS

Salam, this is the last chapter of CSC134 that I'm going to post.  First of all, I start of with definition of system software. 

 

System software consists of the programs that control or maintain the operations of the computer and its devices.  System software have two types.

1. Operating systems (OS)
2. Utility programs

1)  An operating system (OS) is a set of programs containing instructions that work together to coordinate all the activities among computer hardware resources. 

Fuction of OS are:

• start and shut down a computer
• provide a user interface
• manage programs
• manage memory
• control a network
• coordinate tasks

The process of starting or restarting a computer called booting.  There are two type of booting; cold boot and warm boot.

 

Types of operating systems:

• Stand-alone Operating Systems
• Server Operating Systems
• Embedded Operating Systems

2)  A utility program is a type of system software that allows a user to perform maintenance-type tasks.

-A file manager is a utility that performs functions related to file management.  A search utility is a program that attempts to locate a file on your computer based on critiria you specify.

-A disk cleanup utility searches for and removes unnecessary files.

-A disk defragmenter reorganizes the files and unused space on a computer's hard disk so that the operating syatem accesses data more quickly and programs run faster.

 

Hot! Take not! hehe

1. A virus describes a potentially damaging computer program that affects a computer negatively.
2. A worm copies itself repeatedly in memory or over a network.
3. A Trojan horse hides within or looks like a legitimate program.
4. An antivirus program protects a computer against virusses.

Chapter 4 CSC134: TYPE OF STORAGE

Salam, today I want to update on CSC134 of Chapter 4: Type of storage.

Let begin with definition of storage.  Storage holds data, instructions and information for future use.  A storage medium is the physical material on which a computer keeps data, instuctions and information.  Capacity is the number of bytes a storage medium can hold.

• kilobyte (KB):  1 thousand
• megabyte (MB):  1 million
• gigabyte (GB) : 1 billion
• terabyte (TB):  1 trillion
• petabyte (PB):  1 quadrillion
• exabyte (EB):  1 quintillion
• zattabyte (ZB):  1 sextillion
• yottabyte (YB):  1 septillion

The list of storage are:

1. hard disks
2. flash memory storage
3. cloud storage
4. optical dics
5. other type of storage (tape, magnetic stripe card, smart card, microfilm, microfiche

Characteristics of a hard disk include:

• capacity
• platters
• read/writes heads
• cylinders
• transfer rate
• access time

A memory card is a removable flash memory device that you insert and remove from a slot in a computer, mobile device, or card reader/writer.

 

Cloud storage is an Internet service that provides storage to computer users.  Advantages of cloud storage are:

• access files from any computer
• storage large files instantaneously
• allow others to access their files
• store offsite backups
• view time-critical data and images immediately
• provide data center functions

An Optical disc consists of a flat, round, portable disc made of metal, plastic and lacquer that is written and read by a laser.  It typically store software, data, digital photos, movies, and music.

• CD-ROM
• CD-R
• CD-RW
• DVD-ROM
• Blue-ray Disc-ROM (BD-ROM)
• DVD-RW, DVD+RW, DVD+RAM

Tape is a magnetically coated ribbon of plastic capable of storing large amounts of data and information.

 

A magnetic stripe card contains a magnetic stripe that stores information.

 

A smart card stores data on a thin microprocessor embedded in the card.

 

Microfilm and microfiche store microscopic images of documents on a roll or sheet film.

 

 

 

Chapter 3 CSC134: UNDERSTANDING INPUT & UNDERSTANDING OUTPUT

Salam, again today I want to share some knowledge from what I have learn this chapter 3.  Chapter 3 is devide into two, that is 1) Understanding Input, 2) Understanding Output.

1) Understanding Input
Input is any data and instructions entered into the memory of a computer.  An instuctions can be entered into the computer in the form of programs, commands, and user responses.

The example of Input device are:

1. The keyboard is an input device that contains keys users press to enter data and instructions into a computer. There are two types of keyboard. One is wired keyboards (eg: USB port) and the another one is wireless keyboards (eg: bluetooth and IrDA).
2. The ponting device is an input device taht allows a user to control a pointer on the screen.  A mouse is a pointing device that fits under the palm of your hand  comfortably.  Most widely used pointing device on desktop computer and a mouse can be wired or wireless.  Other ponting device are: Trackball, Touchpad, and Pointing Stick.
3. Video games and computer games use a Game controller as the input device that directs movements and actions of on screen objects.  Example of game controller are:  Gamepads, Joysticks & Wheels, Light guns, Dance pads and Motion-sensing controllers.
4. Voice input is the process of entering input by speaking into a microphone.  Voice recognition is the computer's capability of distinguishing spoken words.
5. Audio input is the process of entering any sound into the computer.  Examples are speech, music, and sound effects.
6. Video input is the process of capturing full-motion images and storing them on a computer's storage medium.
7. Touch screens and Touch-sensitive pads
8. Pen input
9. Digital cameras
10. Scanners and Reading Devices
11. Biometric Input

2) Understanding Output
Output is the data that has been processed into a useful form.  Examples text, graphics, audio, and video.  An output device is any type of hardware component that conveys information to one or more people.  Example of output device are:

• display devices; eg: LCD monitors, Plasma monitors & CRT monitor
• printers; eg: A nonimpact printer:- Ink-jet printers, photo printers, laser printers.  An impact printers:- dot-matrix printer, Line printer.
• speakers, headphones, & earbuds
• data projectors
• interactive whiteboards
• force-feedback game controllers
• tactile output

Chapter 2 CSC134: SYSTEM UNIT COMPONENT

Salam, today again I want to post about what I have learn and understand in Chapter 2 of CSC134 subject.
In this chapter 2, it discuss about system unit component of computer.  The system unit itself is a case that contains electronic component of the computer used to process data.   The inside of the system unit on a desktop personal computer includes:

• drive bay(s)
• power supply
• sound card
• video card
• processor
• memory

The 'motherboard' is the main circuit board of the system unit.  A computer chip contain integrated circuits.  The processor, also called the central processing unit (CPU), interprets & carries out the basic instructions that operate a computer.  The control unit is the component of the processor that directs & coordinates most of the operations in the computer.  The arithmetic logic unit (ALU) performs arithmetic, comparison & other operations.

In this chapter 2, I also learned 2 types of memory; volatile memory and nonvolatile memory.
Memory consist of electronic components that store instuctionss waiting to be executed by the processor, data needed by those instructions, and the results of processing the data.  Memory store 3 basic categories of item; 1)  the operating system & other system software. 2)  application programs.   3) data being processed & the resulting information. 

• Volatile memory:  Loses its containts when power is turned off.  Example:  RAM.
• Nonvolatile memory:  Does not lose contents when power is removed.  Examples:  ROM, flash memory &  CMOS.

I also learned about port & connectors.  A port is the point at which a peripheral attaches to or communicates with a system unit (sometimes reffered to as a jack).  A USB port can connect up to 127 diffefent peripheral together with a single connector.  Type of ports are:

• firewire port
• bluetooth port
• SCSI port
• eSATA port
• IrDA port
• serial port
• MIDI port

A connector joins a cable to a port.  On a notebook computer, the ports are on the back, front, and/or sides.  The port types are:

• audio in
• cable tv
• HDMI port
• serial
• speaker
• USB
• Network
• monitor
• firewire
• mouse

In addition, a bluetooth port adapter converts a USB port into a Bluetooth port.  Buses allow the various device both inside & attached to the system unit to communicate with each other. There are 2 types of Buses; 1)  Data bus,  2)  Address bus.

Chapter 1 CSC134: BASIC INTRODUCTION TO COMPUTERS

Salam, today I want to post abaout what I've understand in CSC134 for Chapter 1:  Basic Introduction to Computers.

First of all is the definition of computer.  A computer is an electronic device, operating under the control of instruction strored in its own memory.  A computer contains many electric. electronic, and mechanical components known as 'Hardware'.  The components of a computer are:

• Input device:  Allow you to enter data and instructions into a computer.  Examples: printer, web cam, scanner, microphone, mouse and keyboard.
• Output device:  Hardware component that conveys information to one or more people.  Examples:  monitor/screen and printer.
• System unit:  Case that contains the electronic components of the computer that are used to process data.
• Storage device:  Records (writes) and/or retrieves (reads) items to and from storage media.  Examples:  optical disc device, memory card and USB device.
• Communication device:  Enables a computer to send and receive data, instructions, and information to and from one or more computers or mobile devices.

A computer must have advantages and disadvantages of using it.  The advantages are speed, reliability, consistency, storage and communications.  The disadvantages are health risks, violation of privacy, public safety, impact of labour force and impact of environment.

A computer have seven (7) categories.

1. Personal computers:  A personal computer can perform all of its input, processing, output, & storage activities by itself.
2. Mobile computers & mobile devices:  Mobile computer is personal computer you can carry from place to place.  Examples:  notebook computers, laptop computers, netbooks, and Tablet PCs.  Mobile devices is computing device small enough to hold in your hand.  Examples:  smart phones, PDAs, e-book readers, handheld computer, portable media player an digital cameras.
3. Game consoles:  A geme consoles is a mobile computing device designed for single-player or multiplayer video games.
4. Servers:  A server controls access to the hardware, software & other resources on a network.
5. Mainframes:  A mainframe is a large, expensive, powerful computer that can handle hundreds or thaousands of connected users simultaneously.
6. Supercomputers:  A supercomputers is the fastest, most powerful computer.  Fastest supercomputers are capable of processing more than one quadrillion instructions in a single second.
7. Embedded computers:  An embedded computers is a special-purpose computer that functions as a component in a large product.

Ok, this is the simplest understanding that I could share.  Other or more than this, I must refer back to CSC134 book.  :)

Animation Widget

Dear friend..

If you want to put some cute animation for your blog, you all can go to this link:  http://animaxwidget.blogspot.com/

They have a various choices to choose. 

And this link is the tutorial that can be use as guide for us:
http://bicarafarah.blogspot.com/p/blog-tutorial_1005.html

I know I am still new with blog but I do some research and study; by watch tutorials on youtube, read other's blog and ask my lecturer and friends.

Good luck ^.^'

Laskar Pelangi

 

Hye everyone.. :) 
Tonight I want to share one of my favourite song.  Listen to music is a relaxing and every person have their own way when listening to music.  Some people feel comfortable listen music by using speakers, headphones, or earbuds.  Anyway, the reason why I choose this song is because it is a motivation song.  It can be seen by the lyric.  The song is Laskar Pelangi performed by Nidji.

 

As we can see above here is the lyric.
In my opinion, this song means everyone can dream and have a dream.  There are no limitation for a person to dream, either to be positive or negative person.  This song also means we have to appreciate what we have, keep motivated and positive, and then one day we will gain success.

Below here is the video.  Hope you can understand the meaning of this song by viewing the lyric and video.

Just saying...

Hye, Good Afternoon..  ^-^

At this moment I know my blog is still new and bored, I'm in process to improve it.  Last night till this morning, I've tried to do some changes in my blog but some of it are success but some are not.
I already try to add some music, fancy cursor, and animation, but I remove it back.  It look not suitable and very weird in my blog.

I will learn more about how to decorate these blog and I will practise it in my own blog.  Hope you all can can be patient and love it soon.  Hehehe...

Have a nice day :)

My Worries...

You know what, why  I keep on posting in this blog for all night long till this morning.. I CANT SLEEP!!!
I drank too much coffee just now.  I think that the reason why but it is okay...

Soon I have to get back to college.  Holiday time is very short, just one week.   Not forgotten, even though now is the eid mubarak celebration,  I still remember and think about the tasks given by the lecturer before the holiday.  And also after this holiday, there were lot of  quizes and test waiting for us.
Oh my!  Do you know how it feel?  During holiday you keep on thinking about homeworks, assignments, quizes and tests... 
At the same time, I didn't show my worries toward my family and friends.  I just kept it on my own.  I don't want to  interfere their happiness.  Maybe afterthis I just want to share my problem with my beloved mom :)

Ok, now time shows 3:46 am.. I still cannot sleep and I think I keep on posting in this blog,hehe..
Happy reading.. :)

Raya, Facebook dan Instagram

Wow!!!  Raya, Facebook dan Instagram..

Itulah saya.  Sepanjang bulan Ramadhan dan Syawal ini, saya sering melayari akaun facebook dan instagram saya.  Ini kerana musim perayaan ini ramai kawan-kawan akan memuat naik video, gambar, dan membuat status.  Ia amat menarik untuk dibaca dan dilihat.

Seperti yang kita ketahui, gambar-gambar, video yang sudah dimuat naik di facebook atau instagram pasti tidak akan pernah hilang.  Facebook dan Instagram ini ialah salah satu contoh kepada Cloud storage.  Antara contoh Cloud storage yang lain ialah Youtube, Picasa, Flickr, Gmail, Yahoo! mail ataupun MySpace.

Cloud storage ini mempunyai banyak kebaikan; daripada kita hanya menyimpan gambar dan video di telefon bimbit.  Antara kebaikan cloud storage ini ialah kita boleh melihat gambar dan video yang sudah dimuat naik  pada bila-bila masa. Keduanya, gambar dan video itu tidak akan pernah hilang dan kekal disimpan di cloud storage.  Ketiga, cloud storage boleh menampung saiz fail yang besar.

Sudah tiga hari Syawal ini, banyak kenangan yang telah saya rakamkan dan digambar.  Sesudah ini akan saya buat backup untuk gambar-gambar dan video ini.  Selain disimpan di cloud storage, ada banyak cara lain untuk saya menyimpan kenangan ini.  Saya akan buat salinan dan simpan di pendrive dan memory card atupun burn dalam CD.

Saya rasa anda juga akan buat perkara yang sama seperti saya.  Raya, Facebook, dan Instagram.. :)
Selamat Hari Raya..

Salam Lebaran dari Azrina Azman

Selamat Hari Raya!

Tahun ini ialah tahun pertama kami beraya tanpa nenda yang disayangi.  Hanya kenangan bersamanya yang dapat dibawa semasa lebaran kali ini... Hampir setahun nenda pergi meninggalkan kami semua.  Al-Fatihah...  Biarpun nenda telah meninggalkan kami semua, tetapi segala pesanan, tunjuk ajar, dan kenangan bersama, takkan kami lupakan.

Alhamdulillah, raya tahun ini segalanya dalam keadaan baik-baik sahaja.  Dengan kesempatan ini, saya ingin memohon maaf sekiranya ada kata-kata saya megguris hati dan atas segala kesilapan saya.  Hari ini ialah hari raya ketiga dan suasana di sini sungguh meriah sekali. Saya merayakan Hari Kemenangan ini di Kuching, Sarawak bersama-sama keluarga tersayang.

Seperti yang kita boleh lihat, sempena Hari Raya ini banyak rancangan menarik disiarkan di televisyen.  Untuk mendapat hasil kualiti gambar yang baik, itu bergantung kepada 'resolution', 'brigthness', 'dot pitch', atau 'contrast ratio'.
Bagi diri saya sendiri, kami menggunakan televisyen LCD iaitu Liquid Crystal Display.  Hasil gambar yang ditayangkan juga memuaskan serta menarik.  LCD menggunakan bahan cecair untuk menyampaikan maklumat pada peranti paparan.  Ibu bapa saya amat berpuas hati dan kadang kala kami menikmati masa kami bersama dengan menonton rancangan kegemaran kami.

Baiklah, saya rasa sudah banyak yang saya kongsikan pada pagi ini dan sekarang saya juga tengah menonton televisyen sambil minum segelas neslo panas buatan sendiri dan melayari laman sosial.
Sekali lagi, SELAMAT HARI RAYA AIDILFITRI.. MOHON MAAF ZAHIR & BATIN :) 

Learn and Improve; CSC 134

I still in a learning process and I hope what I have learned in CSC134 subject can be practise in my daily life.  Now my blog is still look like very very new...pity me have to do a new one.  My friends mybe already have a lot of stories or posts to be shared.

Before I forgoten CSC134 is stand for COMPUTER AND INFORMATION  PROCESSING.  For my 3rd semester, we have been introduce to this interesting subject.  We learned about categories of computer, element of an Information System, the system unit, types of memory, storage, the input and output devices, and also system software.

Maybe to some people it sound bored or weird, but to me it is interesting to know new things.  As a student, we must show an interest to a subject so that it be easier for us to understand and memorise the things. :)
As muslim said it more 'berkat' (blessing).

Ok, hopefully I can get an excellent result again for this semester.  Amin. :)

My NEW blog :)

So sad and frustrating when I want to update my old blog today and it can not be opened. Therefore, I have to make a new blog account for CSC134 subjects that I learned now in semester 3 in Diploma Office Management and Technology (BM118).

First of all, in this my new blog I will intro about myself a little bit.  As everyone can see, my name is Azrina Binti Azman and I am studying at Universiti Teknologi Mara (UiTM) Campus Samarahan.
Today I thought to update my old blog but there are problems on the old blog. Without wasting time, I continue to make new blog by the name Azrina's story.  In this new blog I will share some of my daily story... :)

I'm in a process to improve my English.  Hope you all enjoy viewing my blog and sorry for my bad English.
