The system unit is a case that contains electronic components 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 contains integrated circuits

The processor, also called the central processing unit (CPU), interprets and carries out the basic instructions that operate a computer
- Contain a control unit and an arithmetic logic unit (ALU)
   - Multi-core processor
   - Dual-core processor
   - Quad-core processor

The control unit is the component of the processor that directs and coordinates most of the operations in the computer
The arithmetic logic unit (ALU) performs arithmetic, comparison, and other operations
For every instruction, a processor repeats a set of four basic operations, which comprise a machine cycle

Most current personal computers support pipelining
- Processor begins fetching a second instruction before it completes the machine cycle for the first instruction

The Internet is a worldwide collection of networks that links millions of businesses, government agencies, educational institutions, and individuals

The Internet originated as ARPANET in September 1969 and had two main goals:
- Allow scientists at different physical locations to share information and work together
- Function even if part of the network were disabled or destroyed by a disaster

Each organization is responsible only for maintaining its own network
- The World Wide Web Consortium (W3C) oversees research and sets guidelines and standards

Internet2 connects more than 200 universities and 115 companies via a high-speed private network

Many home and small business users connect to the Internet via high-speed broadband Internet service

An access provider is a business that provides individuals and organizations access to the Internet free or for a fee

Tugas-1 Algoritma & Pemrograman II

Untuk para pemirsa yang telah bersedia mampir ke blog ini, sebelumnya saran kritik sangat saya harapkan, so pasti yaa gimana lg, masuk pertama kali eeeh langsung kasih tugas.

Pada tugas Algoritma dan Pemrograman kali ini, saya menitik beratkan pada fungsi string. Yang mana fungsi string ini saya mengkondisikan melalui perulangan IF.

Apabila dalam pernyataan yang berada diatas sama atau masuk salah satu dalam perulangan tersebut, maka eksekusi akan dilaksanakan.

Berikut adalah scriptnya :

• uses wincrt;
• var
• tulisan:string[9];
• i,j,keterangan:string;
• begin
• write('Input Nama Mahasiswa : ');readln(i);
• write('tuliskan NIM Anda    : ');readln(tulisan);
• write('Isikan Alamat anda   : ');readln(j);
• writeln;
• if (length(tulisan)>9) then
• keterangan:='NIM apa ini'
• else
• if(copy(tulisan,3,2)='11') then
• keterangan:='anda Mahasiswa S1'
• else
• if(copy(tulisan,3,2)='31') then
• keterangan:='anda Mahasiswa D3'
• else
• keterangan:='Maaf, anda Bukan Mahasiswa UNISLA';
• clrscr;
• begin
• writeln('Input Biodata Mahasiswa : ');
• writeln('---------------------------');
• writeln;
• writeln('Nama anda  : ',i);
• writeln('Dengan NIM : ',tulisan);
• writeln('Alamat     : ',j);
• writeln;
• writeln('Keterangan : ',keterangan);
• end
• end.

Semoga bermanfaat untuk semua .....

Tabel Konversi Decimal ke Octal Pascal

Pada kiriman yang sebelumnya tentang Tabel Konversi yang dalam bentuk Pdf. Kali ini saya mencoba untuk membuat Tabel Konversi dalam bentuk Pascal.

Ya meskipun gak seluruhnya hasil pemikiran, tapi gak ada salahnya kalau dapat membagi rasa pada anda. Yang tentunya hanya untuk dapat membuahkan manfaat.

Berikut adalah scriptnya...

• uses wincrt;
• var dec,bin,i:integer;
• var a:array[1..100]of integer;
• begin
•       readln(dec);
•       writeln('Angka Decimal : ',dec,' bila di konversi ke octal :');
•       i:=0;
•       repeat
•       i:=i+1;
•       a[i]:=dec mod 8;
•       dec:=dec div 8;
•       until(dec = 0);
•          writeln;
•          for i:=i downto 1 do
•             begin
•             write(a[i]);
•             end;
• readln;
• end.

Gak lupa, apabila ada saran, jangan sungkan...

Sistem Digital ke-2

                                                                   Sistem Bilangan

1. Bilangan Desimal

2. Bilangan Biner

3. Desimal ke Biner

4. Aritmatika Biner

5. Komplemen 1 dan 2

6. Sign Bit

7. Operasi aritmatik dengan sign bilangan

8. Bilangan Hexadesimal

9. Bilangan Oktal

10. Binary Code Decimal (BCD)

11. Digital Code & Parity

Signed Numbers

Sistem digital harus mampu menangani kedua bilangan positif dan bilangan negatif. Sign bilangan biner ditentukan oleh sign dan mangitude

Sign menetukan tanda positif dan negatif sedangkan magnitude mentukan nilai dari bilangan.

Ada tiga bentuk sign integer yang dapat direpresentasikan :
1.Sign-magnitude
2.Complement 1
3.Complement 2
Yang paling penting adalah complement 2 sedangkan Sign- Magnitude yang paling sering digunakan Yang bukan integer dan angka yang sangat besar atau bilangan yang kecil diexpresikan dengan Floating-point format.

Aritmatika Biner
1. Penjumlahan
2. Pengurangan
3. Perkalian
4. Pembagian

Penjumlahan bilangan biner
0 + 0 = 0 Hasil 0 Simpanan 0
0 + 1 = 1 Hasil 1 Simpanan 0
1 + 0 = 1 Hasil 1 Simpanan 0
1 + 1 = 10 Hasil 0 Simpanan 1
