CS101 Assignment # 1 Solution
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.
Another Solution:-
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
Another Solution:-
STATIC RAM vs DYNAMIC RAM
Firstly we anxious with static RAM
1)it does not loose signal strength.
2)no refreshing.
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

CS101 Assignment # 4 Solution
Solution:Pseudocode:
The following can help explain the concept of algorithms in relation to programming.
Problem: Calculate the average of three given numbers.
Let the given numbers be a, b, c
Step 1: Set aside memory for all values (a, b, c,)
Step 2: Assign the values to a memory location (the given numbers)
Step 3: Calculate the average of the values using the formula (a+b+c)/3
Step 4: Display the answer in the proper format, in this case the average.
The problem statement is programmatically solved with the use of four steps in the algorithm.
Problem:Find the gain or loss of an item, as the case may be, and compute the gain or loss percentage, given the cost price and the selling price.
Gain = S.P. (sell price) - C.P (cost price).
Gain % = (Gain * 100)/C.P.
Loss = C.P. - S.P.
Loss % = (Loss * 100)/C.P.
(Percentage gain or loss is calculated on the C.P.)
Algorithm:
Step 1: Obtain the values of S.P. and C.P. Set aside memory for S.P. and C.P., gain percent and loss percent.
Step 2: Assign values to memory location.
Step 3: Perform mathematical computations.
Step 4: Display results in the proper format.
If C.P. = S.P, then
Declare "There is neither gain nor loss in the transaction"
Stop
If S.P. > C.P., then
Calculate Gain = S.P - C.P
Calculate Gain % = (Gain * 100)/C.P
Write "Answer: Gain is $" followed by value of Gain
Write "Answer: Gain % is" followed by value of Gain %
Stop
Else
Calculate Loss = C.P. - S.P
Calculate Loss % = (Loss * 100)/C.P.
Write "Answer: Loss is $" followed by value of Loss
Write "Answer: Loss % is" followed by values of Loss %
Stop
The algorithm is executed in order, starting with Step 1:
In step 1, we set aside memory locations for S.P. and C.P
In step 2, we assign the numerical values of S.P. and C.P. to the memory locations.
In step 3, the answer to the phrase If C.P. - S.P. could be yes or no. If the answer is yes, then only the instructions following the word "then" are executed.
In step 3, if the answer to the phrase S.P. > C.P. is yes, then steps to a to e before else are executed. If the answer to S.P. > C.P. is no, implying that C.P. >= S.P., steps a to e after else are executed.
Step 4 is the last in the process. The result of the computations is displayed and the algorithm is terminated after its execution.
Words such as "IF", "THEN", and "ELSE are used to emphasize their distinctive nature in executing the algorithm.
Flowcharts
When thinking of a Flowchart think of a visual representation of how a process works, depicting the sequence of steps at a minimum. A flowchart offers many advantages including the following.
Helps locate the key elements of a process. It draws clears lines between the end of one process and the start of another.
Brings clarity and improvement to a process.
Helps identify appropriate areas for improvement in a program.
The following shows a format of a sample flowchart that identifies the starting and ending points of a sequential process with decision points.
Pseudocode, aka false code, is an informal language for relating problem solving steps. The steps used in pseudocode are simple and can be implemented with ease into any programming language. Pseudocode uses a combination of English words, mathematical notations, and a set of capitalized keywords such as BEING, END, READ, PRINT, FREAD, FPRINT, IF, ELSE, ELSEIF, ENDIF, WHILE, DO and ENDWHILE.
Pseudocode consists of:
Fundamental control structures such as Sequence, Selection and Repetition.
Three other types of statements, which include Input, Output and Assignment.
Subroutines or small programs that can be added to modularize pseudocode. The subroutines are also written using the pseudocode notation.
Here is an example of pseudocode.
Begin procedure
Input Widget Price
Flowcharts depict different types of actions and steps in a process through special shapes. The sequence of steps and the relationships between these steps is shown using arrows. The following is a list of the different shapes in a flow chart and what they represent.

Cyber Crime:-
Cyber crime is criminal activity done using computers and the Internet. This includes
anything from downloading illegal music files to stealing millions of dollars from online
bank accounts. Cyber crime also includes non-monetary offenses, such as creating and
distributing viruses on other computers or posting confidential business information on
the Internet.
OR
Issues surrounding computer crime have become high-profile, particularly those
surrounding hacking, copyright infringement, child pornography, and child grooming.
There are also problems of privacy when confidential information is lost or intercepted,
lawfully or otherwise.
Two Types of Cyber Crime…
Computer crime encompass a broad range of potentially illegal activities. Generally,
however, it may be divided into one of two types of categories:
(1) crimes that target computer networks or devices directly;
(2) crimes facilitated by computer networks or devices, the primary target of which is
independent of the computer network or device.
Examples of crimes that primarily target computer networks or devices would include,
• Malware (malicious code)
• Denial-of-service attacks
• Computer viruses
Examples of crimes that merely use computer networks or devices would include,
• Cyber stalking
• Fraud and identity theft
• Phishing scams
• Information warfare
More Examples…..
*Fraud achieved by the manipulation of computer records.
* Spamming wherever outlawed completely or where regulations controlling it
are violated.
* Deliberate circumvention of computer security systems.
* Unauthorized access to or modification of
o programs (see software cracking and hacking).
o data.
* Intellectual property theft, including software piracy.
* Industrial espionage by means of access to or theft of computer materials.
* Identity theft where this is accomplished by use of fraudulent computer
transactions.
* Writing or spreading computer viruses or worms.
* Salami slicing is the practice of stealing money repeatedly in extremely small
quantities
* Denial-of-service attack, where company websites are flooded with service
requests and their website is overloaded and either slowed or crashes completely
* Making and digitally distributing child pornography
Now take Examples which one u like and give very briefly
the methods that can be used to minimize the ill effects of
listed crimes.

Definition of Distance Learning:
"Distance learning or education is a field of education that focuses on the pedagogy and andragogy, technology and instructional systems design that aim to deliver education to students who are not physically "On site"
WEB TECHNOLOGY ROLE IN DISTANCE LEARNING:
"Distance learning has received a boost due to the low price of internet communication and the availability of web-based interactive content."
The students who want to continue their jobs with their current jobs this is very convenient option available to them. Physical locating is less of hindrance now. We are turning more and more toward online resources of information
Example:
VU institute is the best example and it better explains the web technology role in distance learning because:
.
VU student are not take lectures through physically teacher presence.
.All their dealings, papers, assignments, quizzes are taken from the student through web technology.
.Students can interact with the other students and the teachers with the help of internet which is actually web technology.
