Answer:
Explanation:
When programming in an OOP language classes are created to represent real-life objects, people, places etc. from the real world. Programming in the general allows you to cut down your code and making it more efficient by applying the same necessary functions to all of the objects that classify under the same category. For example by programming "in the general" and creating an Animal class you can create all of the functions/behaviors that animals tend to have. Then you can apply these functions/behaviors to various animals such as a Cat, Dog, Horse, etc. But if you program in the specific you cannot apply a Cat class to a Dog since they are not the same thing.
Answer:
TRUE
Explanation:
Cache memory is a computer component that help to retrieve data from the computer's memory by acting as a temporary storage area where the computer's processor can retrieve data easily. The temporary storage area is known as cache and is more readily available to the processor than the computer's main memory source.
Although Cache memory is a smaller type of a computer memory that provides high-speed data access to a processor and stores which frequently used computer programs, applications and data.
Cache memory is used to reduce the average time to access data from the Main memory and they stores data so that future requests for that data can be served faster.
Answer:
1. PANs uses Star Topology.
2. LAN uses four topology (Bus, Ring, Star and Tree).
3. MAN uses Star Topology.
4. WAN uses Bus topology.
Explanation:
1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.
2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.
3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.
4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.
