Programming Languages and Software Development Steps
Programming Languages and Their Evolution
When a specific number of steps (k) must be followed, as well as the order in which they must be carried out to perform any activity, we are specifying what is defined as an algorithm. An algorithm can be defined as the sequence of steps that should be taken when there is a problem to be perfectly resolved. Programming is the branch of computer science that allows you to create your own programs to solve various problems.

Troubleshooting Common PC Hardware Problems
Power Supply Issues
Electrical Problems
- Peaks: High-voltage fluctuations in a short period.
- Blackouts: Complete loss of power.
- Surges: Increased voltage during a half period.
- Voltage dips: Opposite of a surge, although the peak is rapidly eliminated.
Power Problems Symptoms
- The PC freezes or restarts for no apparent reason.
- Failures occur on the hard drive, typing errors, file access errors, etc.
- Errors occur when transmitting data between nodes on a network.
- Some internal components fail.
- The lights dim,
Algorithms and Optimization Techniques: Analysis and Applications
Comparing Prim’s and Kruskal’s Algorithms
This section compares Prim’s and Kruskal’s algorithms based on their approach, implementation, and time complexities.
Prim’s Algorithm
- Approach: A greedy algorithm that grows a Minimum Spanning Tree (MST) by adding edges connected to the current MST.
- Efficiency: Works efficiently for dense graphs.
- Implementation:
- Starts from any arbitrary vertex and adds edges connected to the growing MST.
- Selects the smallest edge connecting a vertex in the MST to a vertex not
Assembly Language Operations: 16-bit and 32-bit Processing
Bit Multiplication
1. Move the 16-bit value at memory address 3000 to AX.
MOV AX, [3000] loads the 16-bit value from memory address 3000 into the AX register.
2. Move the 16-bit value at memory address 3002 to BX.
MOV BX, [3002] loads the 16-bit value from memory address 3002 into the BX register.
3. Multiply AX by BX.
MUL BX performs the multiplication of AX and BX. The result is a 32-bit product in the DX:AX register pair, where DX holds the high word and AX holds the low word.
4. Move the low word of

Read MoreProxy Servers: Centralizing Internet Traffic
A proxy server centralizes traffic between the internet and a local network. This way, each computer on your local network does not need a direct internet connection. It is used to control unauthorized access from the internet to the local network.
How Does It Work?
The proxy transforms input and output directions. When a local network computer makes a web application request, the proxy intercepts and processes it. This hides the real IP address of the computer
Euclid’s Algorithm and Convex Hull Computation
Euclid’s Algorithm for Finding the Greatest Common Divisor
Euclid’s algorithm is an efficient method for finding the greatest common divisor (GCD) of two integers. The GCD of two numbers a and b is the largest integer that divides both a and b without leaving a remainder.
Steps of Euclid’s Algorithm
- Base Case: If b=0, then GCD(a,b)=a.
- Recursive Step: If b≠0, replace a with b and b with a mod b (the remainder when a is divided by b).
- Repeat the process until b=0, at which point a is the GCD.
