Different way of answer:
Question 2 (Marks=5)
Differentiate Between Static RAM and Dynamic RAM in Tabular form. ANY TWO Differences
( 2.5 + 2.5 = 5)
SRAM (static RAM). This type of memory maintains data in storage as long as it is powered. Because it is faster and more reliable and expensive than DRAM, SRAM is most often used as cache memory. Earlier forms of SRAM were classified as Async or Sync RAM if they were synchronized with the system clock. The most common type of SRAM today is pipeline burst SRAM, which can operate at higher bus speeds.
DRAM (dynamic RAM). This type of RAM retains its data by being continuously rewritten every few milliseconds. Like SRAM, the data in storage is volatile, meaning it is lost when the system is not powered. DRAM is the most common type of expandable company memory in workstations and servers today, but there are several different types of DRAM.
Static RAM (SRAM)
1. 4 times more expensive
2. Very low access time
3. Can store ¼ as much
4. Information stored on RS flip-flops
5. No need for refreshing
Dynamic RAM (DRAM)
1. Low cost
2. Consumes less power
3. Can store 4 times as much
4. Information stored on FET transistors
5. Needs to be refreshed
STATIC RAM vs DYNAMIC RAM
Firstly we anxious with static RAM
1)it does not loose signal strength.
3)They made of transistors.
Where as Dynamic RAM
1)looses its signal 1 becomes 0
2)periodic refreshing of memory is needed.
3)These are mostly made of capacitors.
(Please select any two difference according to question no 2)
Tabular form (Tabular form means yours answer must have in table format.)
Like this:Static RAM
1)Difference no1 Difference no1
2)Difference no2 Difference no2
