Explanation / Answer
Ans:
[6]
Network Bandwidth: Network Bandwidth is the capacity of a network communications link (wired or wireless network) to transmit those greatest sum of information from one perspective to another workstation system alternately over a computer network in a given amount of time.
Network Topology: A network topology is the course of action of a network or we can call it the arrangements of networks, including its hubs and interfacing lines. There are two approaches of characterizing network geometry: the physical topology and the signal topology. The physical topology of a system is the real geometric design of workstations. There are several common physical topologies, as satar, mesh, bus , etc.

Security of the data and information from unauthorized user is a major task that every company faces in todays time. The advancement of the hackers made it even more difficult for them. In order to prevent this, the company needed to apply some security measures:
{1} Basic System Security Measures: The computers at the workstation should be equipped with basic features of security which provide initial support to the company's data and information. These features include:
1. Strong Passwords: The computers should be password protected with strong password so that it can't be hacked easily.
2. Firewall Protection: Firewall provides security from the unauthorized sites and network interference to the computer. It only allows those incoming connections necessary to fulfill the business need.
3. Malware Protection: The system should be updated with latest malware protection.
{2} Intermediate Security Measures: The system should have intermediate security measures which varies from high level to critical level security. They are as follows:
1. Authorization and Authentication: The user can access the system only after Authorization and Authentication process of the company.

A machine cycle comprises of the steps that a computer’s processor executes whenever it receives a machine dialect direction instruction. Those four steps which the CPU carries out to each machine dialect instruction are: fetch, decode, execute, and store. These steps are performed by the control unit.
1. Fetch: The CU requests the instructions from the primary memory as indicated by the program counter or instruction counter.
2. Decode: Gained info would decoded in the instruction register. This includes breaking those operand field under its parts dependent upon those instruction’s operation code (opcode).
3. Execute: This includes the instruction’s opcode as it tags the CPU operation obliged. The system counter demonstrates the instruction arrangement to machine. These info are orchestrated under those instruction register
4. Store: After all the process the information is stored in the memory.
