Cyber Midterm
1. Who is considered the "father of the computer" and what was the name of the computer he
designed?: Charles Babbage is considered the father of the computer for his work on the
difference engine.
2. How did the invention of transistors impact the evolution of computers?: - Transistors were
smaller, burnt out much less frequently, were more powerful, and faster in comparison to the
vacuum tubes used previously.
3. Briefly explain the significance of the "Moore's Law" mentioned in the video: Moore's Law is the
idea that computer power would exponentially increase every 2 months, the costs would get
lower, and computers would get so small that they could be easily implemented in everyday
life.
4. What role did ARPANET play in the development of computer network- ing?: Arpanet was the
first public switched computer network. It was essentially a prototype of the internet that
humanity uses today.
5. In what decade did personal computers become more accessible to the general public?: Personal
computers became known to the general public in 1977
6. Why is it important to ensure that the computer you choose meets or exceeds the minimum
requirements for the OS you are installing?: Its impor- tant to know that the computer you have
meets the requirements because if the requirements are not met, you may not be able to
install the product correctly.
7. How can you verify that the hardware of a computer without an OS installed is functioning
correctly?: The computers BIOS, which depends on the mother- board, displays information
about the hardware can be accessed without the OS installed.
8. What is the purpose of an ISO file in the context of OS installation, and how can it be used to
install an OS?: ISO files can download large files such as software and operating systems that
would otherwise require a disk to install.
9. When might you need to install additional device drivers during the OS in- stallation process, and
what type of devices do they typically relate to?: Device drivers are usually required for hardware
components of a computer.
10.Why is it usually advisable to choose the default storage configuration during OS installation,
and what is the significance of this choice?: It's usually advisable to choose the default
configuration to ensure that no mistakes are made during the installation and that a clean
install is performed.
11.Explain the significance of providing an initial username and password during OS installation
and how this relates to user accounts.: Providing an initial username and password
combination is important to ensure only certain people have access to the system.
12. Why is it recommended to have knowledge of the network environment when installing an OS,
and what specific network information should you be
1/
, Cyber Midterm
aware of before installation?: It's important to have knowledge of the network environment
that you're installing an OS onto to ensure that the OS can install properly
13.What are some advantages of installing an OS on a virtual machine compared to a physical
computer, and what unique steps are involved in setting up a virtual machine for OS installation?: A
physical computer can have multipurpose use, while a virtual machine can be moved between
hosts, but each has more limited use.
14. What is the minimum CPU requirement for Windows Server, and why is
it important to consider CPU architecture for server hardware selection?: 1.4 GHz is the minimum
requirement for Windows Server. It's important to consider CPU architecture to ensure that the
operating system that you want is able to be installed.
15.Compare and contrast SATA and SAS disks in terms of performance and reliability for server use.
What factors should you consider when choosing be- tween them?: SAS-based hard drives are faster
and more reliable than SATA-based hard drives, but SATA drives have a much larger storage
capacity
16.What are the minimum RAM requirements for Windows Server, and how does server RAM differ
from desktop RAM in terms of features? Why is ample RAM important for server performance?:
Windows Server 2022 requires at least 800MB of RAM. Server RAM supports error correction
code, while desktop RAM does not and is meant for more personal usage. RAM is important
because it temporarily stores data of all applications and processes running.
17. Explain the significance of hot-add memory, hot-replace memory, and
hot-add disk features in server hardware. What benefits do they offer in terms of server maintenance
and uptime?: Hot-add and hot-replace memory, as well as hot-add disk features allow the system
to continue a process without shutting down. This mainly comes in use when the system is
running low on memory.
18.Provide a brief definition of what an operating system (OS) is: Major pro- grams within the
computer program when the system boots up. They act as a way to launch all the other
subsequent programs. A computer typically only has one main OS.
19.Explain the key role that an OS plays in a computer system.: To manage all of the software on
a single computer
20.List the four main functions that an operating system performs.: Ï Storage Management
Ï Process and Service Management Ï
Memory Management
Ï Security and Resource Protection
