Hello, kawan-kawan...
Tahukah kawan-kawan bahawa kadang-kadang kita mudah terlupa dengan pelajaran atau apa juga ilmu serta perkara yang baru kita pelajari sama ada di sekolah atau di rumah. Tahukah kawan-kawan bahawa
ANDA LUPA KERANA...
1)kurang tumpuan
2)kurang teliti
3)kurang minat
4)fikiran melayang atau berkhayal ketika membaca
5)sudah lama berlalu dan tidak diulangkaji
6)dan lain-lain lagi.
Betul ke tak?? Bila dah tau punca, bagaimana kita nak atasinya??...
Caranya ialah :
1) tumpukan sepenuh perhatian ketika melaksanakan sesuatu tugas
2) tingkatkan minat terhadap pelajaran
3) mengulangkaji pelajaran secara berterusan dan bersistematik
4)dan lain-lain lagi.
Jangan asyik belajar sepanjang masa. Amalkan juga makanan yang seimbang dan bersenam pada setiap hari. Ingat, kesihatan badan juga perlu dijaga.LAGIPUN, bukankah badan yang cergas menghasilkan minda yang cerdas! Dari blog http://juniorsixlove.tripod.com/id4.html

SISTEM KOD
Binary Coded Decimal Numbers
Another number system that is encountered occasionally is Binary Coded Decimal. In this
system, numbers are represented in a decimal form, however each decimal digit is encoded
using a four bit binary number.
For example: The decimal number 136 would be represented in BCD as follows:
136 = 0001 0011 0110
1 3 6
Conversion of numbers between decimal and BCD is quite simple. To convert from decimal to
BCD, simply write down the four bit binary pattern for each decimal digit. To convert from BCD to decimal, divide the number into groups of 4 bits and write down the corresponding decimal digit for each 4 bit group.
There are a couple of variations on the BCD representation, namely packed and unpacked. An
unpacked BCD number has only a single decimal digit stored in each data byte. In this case, the
decimal digit will be in the low four bits and the upper 4 bits of the byte will be 0. In the packed
BCD representation, two decimal digits are placed in each byte. Generally, the high order bits of
the data byte contain the more significant decimal digit.
An example:
The following is a 16 bit number encoded in packed BCD format:
01010110 10010011
This is converted to a decimal number as follows:
0101 0110 1001 0011
5 6 9 3
The value is 5693 decimal
Another example:
The same number in unpacked BCD (requires 32 bits)
00000101 00000110 00001001 00000011
5 6 9 3
The use of BCD to represent numbers isn’t as common as binary in most computer systems, as it
is not as space efficient. In packed BCD, only 10 of the 16 possible bit patterns in each 4 bit unit
are used. In unpacked BCD, only 10 of the 256 possible bit patterns in each byte are used.
BCD Digits
0 ................ 0000
1 ................ 0001
2 ................ 0010
3 ................ 0011
4 ................ 0100
5 ................ 0101
6 ................ 0110
7 ................ 0111
8 ................ 1000
9 ................ 1001
Ok.. That's entry for today, I'll bee continue topic addition and subtraction for next entry..
