anyone can help me with this binary question please?

Question

Binary & Denary Conversions



A. DENARY SYSTEM

This is a base ‘10’ system, where if you work in columns, the value of the next column along is “10 times” that of the one to its right ie, the number ‘1729’ would be represented as follows :-


ThousandsHundredsTensUnits

1729



B. BINARY SYSTEM

This is a base ‘2’ system, so the binary number 1011 in columns would be as follows :-


(MSB)(LSB)
EightsFoursTwosOnes

1011


MSB=Most Significant Bit
LSB=Least Significant Bit


Thus in denary the binary number ‘1011’ would become :-

(1 x 8) + (0 x 4) + (1 x 2) + (1 x 1)=11







Binary Data Activity


From your basic understanding of Digital signals & binary information, attempt all of the following questions :-



1. You read in the small ads of a Computer Magazine that a supplier is offering an old 486-SX PC, with 640 Kbytes of memory, together with a 320 Kbytes memory upgrade for the price of £100.00

However another supplier is offering a similar specification 486-SX PC, but with 1 Million bytes of memory for a price of £120.00

Which is the better deal ?, and remember to show all calculations & workings.

Answer 1

Here you must remember that 1 Kbyte isn't 1000 bytes, but is 2^10 = 1024 bytes.

First computer: mem = (640 + 320) * 1024bytes = 983040 bytes

Second computer: mem = 1000000 bytes



First computer has about 2% less memory for about 16% less price

and therefore is the better deal.

Answer 2

I'm making good profit with penny stock

Many new investors are lured to the appeal of a penny stock due to the low price and potential for rapid growth which may be as high as several hundred percent in a few days. Similarly, severe loss can occur and many penny stocks lose all of their value in the long term. Accordingly, the SEC warns that penny stocks are high risk investments and new investors should be aware of the risks involved but you can even make very big money. These risks include limited liquidity, lack of financial reporting, and fraud. A penny stock is a common stock that trades for less than $5 a share. While penny stocks generally are quoted over-the-counter, such as on the OTC Bulletin Board or in the Pink Sheets, they may also trade on securities exchanges, including foreign securities exchanges. In addition, penny stocks include the securities of certain private companies with no active trading market. Although a penny stock is said to be "thinly traded," share volumes traded daily can be in the hundreds of millions for a sub-penny stock. Legitimate information on penny stock companies can be difficult to find and a stock can be easily manipulated.
