True and False(Total points: 10) 1. The CPU is responsible for moving the data between the peripheral devices that it controls
and its local buffer storage.
2. A linker is used to load the binary executable fle into memory, where it is eligible to run on a
CPU core.
3. When a process creates a new process, it must wait until its child has terminated.
4. TLS data are visible across function invocations but can not be accessed by other threads in the same
process.
5. The multilevel queue scheduling algorithm allows a process to move between queues.
6. The main disadvantage of mutex is that it requires busy waiting.
7. The resource-allocation-graph algorithm is applicable to a resource allocation system with multiple
instances of each resource type.
8. In virtual memory page replacement, increasing the number of frames always decreases the page-fault
rate.
9. DMA can release the CPU from the burden of transferring data between memory and disks, but it is
applicable only when the memory addresses are contiguous.
10. To improve I/O efficiency, I/O transfers between memory and mass storage are performed in units of
blocks, which is usually multiple of 512 bytes.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.

Database uses the approach of programming while both the data and the processing instructions are stored in the database.
