INTERNET . :)

INTERNET

- The Internet is a globalnetwork connecting millions of computers. More than 100 countries are linked into exchanges ofdata, news and opinions.
-  According toInternet World Stats, as of December 31, 2011 there was an estimated 2,267,233,742 Internet users worldwide. This represents 32.7% of the world's population.

- Unlike online services, which are centrally controlled, the Internet is decentralized by design. Each Internet computer, called a host, is independent. Its operators can choose which Internet services to use and which local services to make available to the global Internet community. Remarkably, this anarchy by design works exceedingly well. 
- There are a variety of ways toaccess the Internet. Most online services offer access to some Internet services. It is also possible to gain access through a commercial Internet Service Provider (ISP).

Network

Assalamualaikum,

This week I would share about what I've have been learn about computer network. It is simply a group of interconnected computers. Two or more computers are connected via hardware or software, and able to communicate with each other.

Network computer is a major components of a computer network, for example;

1. Communication
2. Media
3. Interconnecting Devices
4. Computers
5. Networking

The data transmission characteristics is :

• Bandwidth (rate of transmission)
• Analog or Digital (type of signal)
• Serial or Parallel (order of bits)

Communication Channel

-To send data through the channel requires some type of transmission media, which may be either physical or wireless.

Network Medium

- Computers share access to common network medium that carries signals from one computer to another.

- Medium may be physical cable, such as twisted pair, coaxial, or fiber-optic.

- Medium may also be wireless.

PHYSICAL MEDIA

WIRELESS MEDIA

•       Microwave system – transmits data via high-frequency radio signals through the atmosphere

•       Satellite system – receive transmitted signals, amplify them, and then transmit the signals to the appropriate locations

•       Cellular technology – uses antennae resembling telephone towers to pick up radio signals within a specific area (cell)

•       Infrared technology – transmits data as infrared light waves from one device to another, providing wireless links between PCs and peripherals

3 TYPES OF NETWORK :)

•   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)

•   Network spread geographically (Country or across Globe) is called WAN (Wide Area Network)

Peer-to-Peer Networking Advantages

•       Easy to install and configure

•       No dedicated server

•       Users control own shared resources

•       Inexpensive to purchase and operate

•       No additional equipment or software

•       No dedicated administrators

•      Works best with 10 or fewer users

Peer-to-Peer Networking Disadvantages

•       Security applies to single resource at a time

•       Users may have many different passwords

•       Must back up each machine individually

•       Machine sharing resources may suffers reduced performance

•       No centralized organization scheme to locate or control access to data

•       Does not usually work well with more than

10 users

that s all that i can share in network topic . theres a lot information to complete this topic, but just this all i can share . see again . :)

Computer 2 ~ SOFTWARE ~

Software is set of instructions or program in computer.

-is a collection of computer programs together that related to the data.

-there's have 3 categories software that system software, application software and programming software.

SOFTWARE LAYER.

Computer users

Application

Operating system

Device driver

System software

Computer Hardware

•  APPLICATION.

Word processing,email,internet and so on.

• OPERATING SYSTEM

A set of program that coordinates all activities among computer hardware resources.

OS receive order from the user via application program.

• DEVICE DRIVER

Device driver are very low level instruction to a device like, the printer and the hard driver.

It also allow OS directly accesses  hardware resources.

• PROGRAMMING LANGUAGE

Is a language designed to communicate, instruction to a machine,particularly a computer.In there have 2 important things that we have to remember:

Low level language

That is closer to the hardware than are high level programming language,which are closer to human language.Have two types in there:

-Machine language =the first generation PL

It's use series of binary digits( 1s-0s) or combination of numbers and letter that represent binary digits.

-Assembly language =the second generation PL

Programming is written using symbolic instruction codes  called mnemonic.

Also use symbolic memory address.

THIRD GENERATION LANGUAGE

Third generation language is (3GLS))are the first to use true English phrasing ,making them easier to use than previous language.It's also known as Procedural Language like FORTRAN AND COBOL.

FOURTH GENERATION

Is (4GLs)are even easier to use than 3GLs.Also known as non-procedural language.4GLs use a text based environment like 3GLs.The following 4GLs is Visual Basic(VB),Visual Age and Authoring Environment.

FIFTH GENERATION

5GLs are issue of debate in the programming community Fifth generation are designed to make a computer solve a problem without the programmer.These high language would use artificial intelligence  to create software,and making 5GLs extremely difficult to develop.

thats all that i can share in this topic . see again :)

Computer 1 ~ Hardware

assalamualaikum.

this week, i have learn about computer hardware. i would like to share what information that i get with the reader of my blog. :) Actually , computer have 2 component that is hardware & software.

Hardware is a physical part of computer.
-computer hardware include ; input device, output device, system unit, storage device, and communication device.

Computer hardware basics ; comp history, architecture, motherboard, CPU & etc.

• Person's who invent computer

                1- Blaise Pascal (1642)

                2- Gottfried Leibniz 

                3- Josept - Marie Jacquacd

                4- Charles Babbage.

• Computer Architecture is the field of study of selecting and interconnecting hardware components to create computers that satisfy functional performance and cost goals. 

• Motherboard also called system board. Contains chips, integrated circuits, and transistors.

• CPU = memory + processor. (CENTRAL PROCESSING UNIT)

That is just what i can share . but theres a lot that i didnt include in this post, such as RAM, hard disk, storage, I/O device , and etc. that's all from me. will continue with another post . :)

Generation and Categories of Computer

Salam ,

Today , i would like to share what i've learn about this topic. All computer have hardware and software. First of all, i've learn the generation of computer, computer have 5th generation . 

The first generation is vacuum tube, second is transistor, third one is Integrated circuit or as known as IC, fourth is VLSI/ULSI, and the last is Artificial Intelligence.

GENERATION OF COMPUTER

1. Vacuum tube
2. Transistor
3. Integrated Circuit (IC)
4. VLSI/ULSI
5. Artificial Intelligence.

Besides that, computer also was categories into 6 based on size,capability and price. The categories of computer is :

1. Embedded computers
