Explanation:
The flowchart is pretty straightforward since there are no decisions to make.
Answer:
VPN is the only solution where Renee can connect to the office network were wan technology is configured.
Explanation:
VPN connections are made through internet connection. To establish the connection at both ends we need the internet.
At one side especially at the office end if any STATIC IP is available it is easy to establish the connection.
Normally if one end is STATIC IP then VPN connection speed depends on STATIC IP speed. Suppose at both end VPN CONNECTION is made by dynamic address then maximum speed is achieved only 484 kbps. It is nothing but the speed of USB.
Answer:
Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.
