However, data access in disk caching is slower in comparison to memory caching.ĭisk cache sizes can range from 128 MB in normal hard disks to 1 GB in solid-state disks (SSDs). Caching in RAM is referred to as memory caching, while caching in a hard disk is referred to as disk caching.ĭisk caching is advantageous because cached data in the hard disk isn’t lost if the system crashes. It can exist in either RAM or a hard disk. zero capacity: buffer memory size is zero, blocks all senders until the data is receivedĬache memory is a fast, static random access memory (SRAM) that a computer chip can access more efficiently than the standard dynamic random access memory (DRAM).unbounded capacity: buffer memory size is unlimited, accepts any amount of data from senders.

bounded capacity: buffer memory size is limited, blocks senders if full.If the application changes the buffer data before the system call returns, copy semantics offers a version of the data at the time of the last system call.īuffers are executed in three capacities: Let’s assume an application has a buffer to write to the hard disk and that it executes the write() system call. On the receiver’s end, the system creates a buffer that collects the fragmented packets of data and reassembles them to their original format.īuffering supports copy semantics for an application’s input or output (IO). From the sender’s side, the system breaks down a large chunk of data into small packets and sends them over the network. In computer networking, buffers are useful in data fragmentation and reassembly. The system automatically creates a buffer and fills it with the document’s data so that it doesn’t have to wait for the printer before processing the next page. When you have some spare time, take a look at the /proc filesystem on your Linux system for other system information you can find, including /proc/loadavg, /proc/vmstat, and much more.Buffers are useful when printing long documents. I hope these Linux processor and memory commands have been helpful. Summary: Linux processor and memory commands When I issue the Linux memory information command, I see the following output:Īs you can see, my current Linux system has 2 GB RAM, with all the additional memory information shown there.

Model name : Intel(R) Pentium(R) 4 CPU 3.00GHzįlags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe constant_tsc pni monitor ds_cpl cid xtprįrom that output I can see my current system is a two-processor Intel system, with additional information about the Intel CPU (CPUs, actually).

When I issue that Linux processor information command on my current hardware system, I see this output: (See below for sample output.) Linux processor command output To see your Linux memory information and memory stats use this command:

How to show Linux memory information To see what type of processor/CPU your computer system has, use this Linux command:Īs you can see, all you have to do is use the Linux cat command on a special file on your Linux system.
