Homework 4 – Computer Memory

1. A bootstrap loader is a program that runs before any other program can run. It is stored in ROM so it can be used when the computer has been switched on and off. It gives the processor instructions on how to find the operating system.
2.
3. Bootstrap loader.
4. The use of the cache memory makes the processor more efficient by reducing the time it takes to get instructions from main memory. This in turn makes the computer faster.
5.
6.

Homework 5 – Performance

1. Cache memory cuts the time it takes for the processor to get instructions from main memory thus making the processor faster and more efficient.

2. No it is not, several TEACHER UR A DIK DO U EVN LIFT?
3. ther factors such as processor speed and memory capacity need to be assessed.

4. Measuring the number of FLOPS is a better approach than measuring MIPS as it can take up to 5 seconds to carry out an instruction.

4. They measure the time to do set tasks which gives a clear indication of how good a computer is compared to others.

5. So that the computer can print etc smoothly and not have to wait too long.

6. It might not have a big enough address bus thus not be able to use the big data bus to its full potential.

7. The bigger the word size, the higher number you can represent through binary.

8. MIPS affects system performance by determining how many million instructions a computer can carry out in a second.

9. A cache makes the computer run smoother by making it quicker to get instructions

Computer and Memory Essay

efficient design and allow computers to perform multiple functions rather than being used for one specific purpose. The Von Neumann model uses memory, system buses, and Boolean operators to communicate programs and perform functions. The computer is an electronic device that operates under the control of instructions that are stored in memory. The idea of storing memory or instructions within the computer came from John Von Neumann. Von Neumann architecture can be described as a stored program design. A…

Also known as the CPU (Central Processing Unit). It is the brain of the computer. You can have different types of cores stored in the processor. You can have single core, dual core and a quad core, the bigger you have the better it is. Its main job is to receive input and give the appropriate output. The processor can handle trillions of calculations per second. (Random Access Memory) It is a computer data storage that allows information to be stored and accessed any time and from different locations…

What is CPU? CPU is short for Central Processing Unit. It was first developed at Intel with the help of Ted Hoff in the early 1970’s. It’s commonly known as the brain of the computer as it does anything instructed from any type of hardware, such as your keyboard and mouse. CPUs process commands it receives from decoding the code in programs and many other files. A CPU has four primary functions: fetch, decode, execute, and writeback.

Computer Architecture Essay

architecture on June 30, 1945. The central processing unit (CPU), the memory, and the input/output devices (I/O) are the main three building blocks of the Von Neumann computer systems connected using the system bus. The components of the model are composed of memory, arithmetic logic unit (ALU), input/output, and the control unit. The memory is where all the data information is stored, in present computers it is call the RAM. The ALU is where the calculation and processing of information take place. The…
