Hi! I have been troubleshooting and building PCs all my life and I find it very important to know the the internal core components of a PC and how they function that way when errors occur you can attempt to fix the problem.
Ex1: Lets say your BIOS identifies a problem with a RAM slot you would be able to know that your RAM slot is either shorted or there is a problem with the RAM stick you inserted.
Ex2: Now your monitor is flashing and turning colors randomly. You could make an inference that either your monitor is prongs are broken, your cable prongs could be bent, your cable might not be plugged in all the way, or your external or integrated GPU is toast.
Hope this might've showed you something

Answer:
(D) Network Standard.
Explanation:
Networking standards ensures the ability of networking technologies by defining the guidelines of communication that specify way computer access the medium they are attached.Network standards also defines which type of transmission transmission to use wireless or wired,which media to use etc.
Answer:
a. 2^6, or 64 opcodes.
b. 2^5, or 32 registers.
c. 2^16, or 0 to 65536.
d. -32768 to 32768.
Explanation:
a. Following that the opcode is 6 bits, it is generally known that the maximum number of opcodes should be 2^6, or 64 opcodes.
b. Now, since the size of the register field is 5 bits, we know that 2^5 registers can be accessed, or 32 registers.
c. Unsigned immediate operand applies to the plus/minus sign of the number. Since unsigned numbers are always positive, the range is from 0 to 2^16, or 0 to 65536.
d. Considering that the signed operands can be negative, they need a 16'th bit for the sign and 15 bits for the number. This means there are 2 * (2^15) numbers, or 2^16. However, the numbers range from -32768 to 32768.
Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
