What is loop control in C? Different between while () loop and do while () loop with suitable example.

What is loop control in C? Different between while () loop and do while () loop with suitable example. Answer: - Loops are used to repeat a block of code. Being able to have your program repeatedly execute a block of code is one of the most basic but useful tasks in programming - many... Continue Reading →

Why array is different from pointer explain with example?

Why array is different from pointer explain with example? Answer: - Bothe array and pointer allocate memory previously before storage data in memory location both arrays and pointers are used to store large amount of same data in memory location. Arrays are used in C programming for static memory allocation. It allocate memory at compile... Continue Reading →

What do you mean by wireless communication system? Explain about microwave and radio wave communication system.

What do you mean by wireless communication system? Explain about microwave and radio wave communication system. Answer: - Wireless communication is the transfer of information or power between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as... Continue Reading →

What do you mean by guided and unguided media? Describe about various type of cable?

What do you mean by guided and unguided media? Describe about various type of cable? Answer: - Telecommunication links can broadly be classified into two categories, namely, guided media (wired) and unguided media (wireless).

What are universal gates? Explain with suitable example.

What are universal gates? Explain with suitable example. Answer: - The NAND gate and nor gate are universal gate because its repeated use can produce other logic gates. The table below show how NAND gates can be connected to produce inverter (i.e., NOT gate) AND gate and OR gate. (1) NOT gate from NAND gate:... Continue Reading →
