Just to the right of the CPU are a couple support chips. Prominently, one of the chips is covered with a copper "heatsink".. Here the mechanism is released so the CPU can be picked up.

The fingernail sized CPU is packaged underneath this metal cover which helps conduct the heat from the CPU up to its heatsink. The gray stuff on the metal chip cover is "thermal paste", a material which helps conduct heat from the chip housing to its not shown heatsink. CPU chip in metal package Heatsink has been removed Bottom of package.. Each pad is connected by a very fine wire to a spot on the silicon chip.

Here is a picture of another chip, but with the top packaging removed. You see the pinky-fingernail silicon chip at the center with the tiny transistor details etched onto it. At the chip edge, see the very fine wires connecting parts of the chip to outside pads CC licensed attribution sharealke 3.

Introduction to Computer Hardware Part 1.pdf

This is a standard disk size to use inside a desktop computer. Laptop computers use 2. This is also known as a "thumb drive" or "USB key".

It is essentially a USB jack connected to a flash storage chip with some support electronics: Flash drive the other type of persistent storage i.

This chip can store about 1 billion bits.. One of the oft seen topics in Computers is Hardware. Basic Computer Hardware questions are easy to remember and can count for easy marks. Download as PDF for revision later.

Parts that were once hand made at a cost of thousands of man-hours are now mass produced for a fraction of a rupee. Computer parts can be divided into two groups, hardware and software.

Hardware is any part of the computer that you can touch. The seeming miles of wires that get tangled on your desk, the CD drive, the monitor are all hardware.

Software is a set of electronic instructions consisting of complex codes Programs that make the computer perform tasks. Windows is a software, so is any other program that runs on your computer. While there are thousands of parts even in the smallest computers that make up its hardware, you are not required to know them all. You only need to know about basic computer hardware. Basic computer hardware consists of the following parts: 1.

It performs all types of data processing operations, stores data, intermediate results and instructions program. It controls the operation of all parts of computer. A CPU has 3 components as listed below. The ALU thinks in bits i. It is made up of a group of memory locations built directly into the CPU called registers.

These are used to hold the data binary information that are being processed by the current instruction. C Memory Primary memory is memory that is part of the computer itself and necessary for its functioning. As soon as the machine is switched off, data is erased.

RAM is volatile. Volatile means that the data stored in memory is lost when we switch off the computer or if there is a power failure. There are different types of RAM available. Some of them are described below.

Persistent Storage, Newer Technology: Flash "Flash" is a transistor-like persistent storage technology "solid state" - no moving parts -aka "Flash drive" -aka "Flash memory" -aka "SSD": Solid State Disk Flash is better than a hard drive in every way but cost - faster, more reliable, less power Flash is more expensive per byte Formats: usb key, SD card in camera, flash storage built into a phone or tablet or computer Flash used to be very expensive, so most computers used hard disks Flash is getting cheaper Moore's law However per-byte, hard drives are still substantially cheaper Not to be confused with "Adobe Flash", a proprietary media format Warning: flash does not persist forever.

It may not hold the bits past 10 or 20 years. Nobody knows for sure Persistent storage - long term storage for bytes as files and folders. Persistent means that the bytes are stored, even when power is removed.

A laptop might use a spinning hard drive also known as "hard disk" for persistent storage of files. The hard drive reads and writes magnetic patterns on a spinning metal disk to store the bytes, while flash is "solid state": no moving parts, just silicon chips with tiny groups of electrons to store the bytes.

In either case, the storage is persistent, in that it maintains its state even when the power is off.

A flash drive is faster and uses less power than a hard disk. However, per byte, flash is significantly more expensive than hard drive storage. Flash has been getting cheaper, so it may take over niches at the expense of hard drives. Note that Adobe Flash is an unrelated concept; it is a proprietary media format.

Flash storage is what underlies USB thumb drives, SD cards for use in cameras, or the built-in storage in a tablet or phone. File System How are the bytes in persistent storage organized? Bytes on a flash drive?

Typically the hard disk or flash disk is formatted with a "file system" which organizes the bytes into the familiar pattern of files and directories, where each file and directory has a somewhat useful name like "resume. When you connect the drive to a computer, the computer presents the drive's file system to the user, allowing them open files, move file around, etc. Essentially, each file in the file system refers to a block of bytes, so the "flowers.

The file system in effect gives the user a name and probably an icon for a block of data bytes, and allows the user to perform operations on that data, like move it or copy it or open it with a program.You see the pinky-fingernail silicon chip at the center with the tiny transistor details etched onto it.

An SSD emulates a hard disk drive, thus easily replacing it in any application. In the recent period more and more people are interested in taking computer hardware courses and tutorials.
