Answer:
5 MB.
Explanation:
1 foot = 12 inches
2400/9=266.66 feet per track
1 track excluding, remaining 8 track =2400 - 266.66 = 2133.33 feet
so, space available to store data = 2133.33 feet
now, 2133.33 feet = 25600 inches
total data that can be stored = 25600 * 1600 = 40960000 bits
= 46080000/8 = 5120000 Bytes
= 5120000/1000000 = 5.12 MB = 5 MB (approx.)
Answer:
A motherboard will require DDR3 type of memory.
Explanation:
In the motherboard, we use DDR3 RAM. It stands for "Double Data Rate 3" full name of this ram is DDR3 SDRAM where SDRAM stands for "Synchronous Dynamic Random-Access Memory". It was firstly implemented in the 1970s.
- DRAM is not clock-controlled.
- The DRAM is asynchronous RAM i.e. with no Synchronous replication of external stimulus.
Answer:
By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.
By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.
The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.
