NETWORK

Network from system of data communications to involve one or more system computer which to connect with line transmission of communication to form one system. With network, computer which one can use the data which to get on other computer. Network to form the way of very good for integrating system information and to channel the information current from one area to other area. To form a system network, required a special software communication, that is protocol.

Component from a network is node and link. Node is dot which can accept the data input into network or yield the output information. Node can be in the form of a printer or appliance print other, or a PC or micro computer until big mainframe computer.

Link is channel or transmission line or carrier for the current of information or data of among node. Link can be in the form of the cable , microwave system, laser of system or satellite system. Network which is each located node in location which far one with other and use the link in the form of transmission line of long distance that is WAN (Wide of Area Network). While network which is each separate node in distance which local and use the link in the form of transmission line cable that is LAN ( Local Area Network).

Asking & Answering Questions

1. Asking & answering questions

• Yes / No Questions (Do or did)

Dou you like play football?
Yes, I do

Football very liked by everybody and all circle. Many people liked football. Because this sport playable by many people. In a team have eleven player to play at field, and there are some player as reserve player, and in a match there are referee and referee assistant.

COMPUTER SYSTEM

So that computer applicable to process data, hence have to the in form of system computer. System is network from at elements which interact. Forming one union to execute target from the system.

Target from system computer is data process to yield the information. An the fundamental target executed, hence elements there must be supporting. Elements from system computer is software, hardware, and brainware.

• Hardware is equipments of system computer which physically seen and can be touched.

• Software is containing program govern to processing data.

• Brainware is human being in concerned in operating and also arrange the system computer.

Third of the element system computer to have interact and form one union. Hardware without existence of software, hence will not function such as those which expected, only in the form of dead object. Software to operate the hardware. Hardware done supported by software nor will function except that there is human being operating.

Meaning Assembler

Assembler is language computer which position among language of machine and high language level for example Language of C or Pascal. Language of C or Pascal told as high language level because hence easy statement and words understood by human being, though a long way off differ from the real human being language. Machine language is binary code representing instruction which deflect run by computer. Program in language assembler consisted of by some code operate(op code) and pseudo ops. Op Code is command to be executed (usually written in mnemonic), while can be consisted of the source and address target. Pseudeo Operation ( pseudo op) is a command to assembler to announce what must be done to data, conditional branching, govern the macro and listing.

REGISTER IN ASSEMBLER

Register represent some of microprocessor which can be accessed with the very high speed. Register divided to become 5 shares that is :

1. Segment Register, consisted of the register CS(CODE Segment), DS(DATA Segment), ES(EXTRA Segment) and SS(STACK Segment).
   
2. Pointer And Index Register, consisted of the register SP(Stack Pointer), BP(Base Pointer), SI(Source Index), DI(Destination Index).
   
3. General Purpose Register, consisted of the register AX, BX, CX, and DX. This Register each representing register 16 bit which can be disjointed to become 2 shares, where each shares consisted of 8 bit, that is register AH, AL, BRA, BL, CH, CL, DH, DL.
   
4. Index of Pointer Register, consisted of the register IP. this Register IP paired by register CS ( CS:IP).
   
5. Flags Register.

INPUT, OUTPUT and LOOPING IN ASSEMBLER

INPUT AND OUTPUT CHARACTER

• Input Character use the interrupt 21h and service 01h.
  
• Output Character use the interrupt 21h and service 02h.

INPUT AND OUTPUT SENTENCE

• Input Sentence use the interrupt 21h and service 0ah.
  
• Output Sentence use the interrupt 21h and service 09h.

LOOPING
Looping executed in register CX as counter to the number of looping to be executed.

Linus Torvalds

Linus Benedict Torvalds (lahir 28 Desember 1969 di Helsinki, Finlandia) adalah rekayasawan perangkat lunak Finlandia yang dikenal sebagai perintis pengembangan kernel Linux. Ia sekarang bertindak sebagai koordinator proyek tersebut.
Linux terinsipirasi oleh Minix (suatu sistem operasi yang dikembangkan oleh Andrew S. Tanenbaum) untuk mengembangkan suatu sistem operasi mirip-Unix (Unix-like) yang dapat dijalankan pada suatu PC. Linux sekarang dapat dijalankan pada berbagai arsitektur lain.
