PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.
The CPU flag for AMD-V is "svm". This may be checked in BSD derivatives via dmesg or sysctl and in Linux via /proc/cpuinfo. [19] Instructions in AMD-V include VMRUN, VMLOAD, VMSAVE, CLGI, VMMCALL, INVLPGA, SKINIT, and STGI. With some motherboards, users must enable AMD SVM feature in the BIOS setup before applications can make use of it. [20]
The computer first executes a relatively small program stored in the boot ROM, which is read-only memory (ROM, and later EEPROM, NOR flash) along with some needed data, to initialize hardware devices such as CPU, motherboard, memory, storage and other I/O devices, to access the nonvolatile device (usually block device, e.g., NAND flash) or ...
The PlayStation 5 is powered by a custom system on a chip (SoC) designed in tandem by AMD and Sony, [45] integrating a custom 7 nm AMD Zen 2 CPU with eight cores running at a variable frequency capped at 3.5 GHz. [46] Zen 2 is a 64-bit x86-64 instruction set CPU microarchitecture.
Collisions have occurred when manufacturers assign a default UUID to a product, such as a motherboard, and then fail to over-write the default UUID later in the manufacturing process. For example, UUID 03000200-0400-0500-0006-000700080009 occurs on many different units of Gigabyte -branded motherboards.
A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys.
