1. 3 times the light voltage, ie., 3*0.5 = 1.5V
2. Total R = 3*25 = 75Ω, V=1.5V, I = V/R = 1.5/75 = 20 mA
3. A 1.5V battery (e.g., an AA battery) with a charge of at least 20mAh. AA batteries should be able to handle this easily.
Answer:
T(n)=n(n+1)/2
Explanation:
See the attached picture for detailed explanation.
5GL or the fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. Fifth Generation Programming or Visual programming language, is also known as natural language. It provides a visual or graphical interface, called a visual programming environment, for creating source codes.
Answer: Switch, router, firewall
Explanation:
The function of the switch is to distribute the network to different networks similar in functioning to that of the hub but it performs filtering of the traffic present in the network using various traffic filtering algorithms.
The router whose main function is to route packets across the network is also used to connect between LANs and between LAN and a WAN.
The firewall is typically installed on systems or in servers or in routers with it most important function to filtering the traffic and minimize the packet delivery delay in LANs.
Answer:
False
Explanation:
The transport layer is found in both OSI and TCP/IP suite model. It segments and propagates packets across a network. TCP and UDP are protocols in this layer.
UDP is a connectionless protocol, that is to say, it needs no connection for transmission to take place. UDP transfer is unreliable as packets lost are not retransmitted. Unlike the TCP, it's header is smaller and it is faster in transmission, and links to destinations are random and not determined by the source.
