Intro to Pc Operating System Chapter1

2. Which of the following is an example of the hardware component of an information system?

Operating Systems are complex pieces of software that are designed for powerful hardware, easily capable of running many programs at once, the prioritize hardware task requests known as ‘system calls’ and allocate them memory space or processing time as needed.

Input: An input is when a computer receives data from external hardware such as a mouse, keyboard

19. Some hardware can be added to the computer without having to restart or power down the computer. After a short period of time the device driver automatically loads and the hardware is available to applications and the user. This type of hardware is considered compatible with what type of technology?

Symmetric multiprocessing treats all processors similarly. I/O can be processed on any processor. The processors interconnect with each other as needed. It allows many processes to be run at once without corrupting performance. Symmetric multiprocessing treats all processors similarly. I/O can be processed on any processor. The processors interconnect with each other as needed. It allows many processes to be run at once without corrupting performance. Three advantages of multiprocessing are: Increased throughput - with more processors, more work can be accomplished in less time; Economy of scale - peripheral devices may be shared amongst multi-processor systems; increased reliability - if one processor crashes, then the others may continue to operate. One disadvantage of a multi-processing system is the added difficulty in operating system and possibly application software. Another limitation of SMP is that as microprocessors are added, the shared bus get overloaded and becomes a performance bottleneck. Symmetric Multiprocessor Master-slave multiprocessor is not reliable as if the master processor fails the whole system goes down.

1.1) Give 5 types of hardware resources and five types of data or software resources that

In centralized computer or minicomputer frameworks the assets like memory, stockpiling of information and system data transfer capacity ought to be managed carefully.

a. The CPU tells the RAM which address holds the data that the CPU wants to

assign process identification, allocate address space, initialize process control block, set appropriate linkage, create or expand data structure

4. Applications where various of machines can be doled out for each to do a task e.g every processing a single file

5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of the following is true about the process of read data. As described in the chapter?

a. The Input / Output Process - simply put anything that puts input into the computer is an Input device, such as a keyboard or mouse. Output is what comes out such as typing on the keyboard will give you output on your display monitor and some things do both such as a hard drive.

Assembly language uses a mnemonic to represent each low-level machine operation or opcode. Some opcodes require one or more operands as part of the instruction, and most

When a CPU is composed of two or more processors, each one is referred to as a(n) ________.

This is a basic view of standard interrupt handling. Additional or alternative solutions continue to be developed and added across many different platforms. Here are some additional approaches.
